Description

Catalyst carrier processing and cutting device

Technical Field

The invention relates to the technical field of catalyst carrier cutting, in particular to a catalyst carrier processing and cutting device.

Background Art

Catalyst carrier, also known as support, is one of the components of supported catalysts and the skeleton of the active components of the catalyst. It is used to support the active components and disperse the active components. It can also increase the strength of the catalyst. The hollow columnar alumina catalyst carrier is a catalyst carrier with a special shape. This alumina carrier is widely used in petrochemical, hydrodesulfurization, low-transformation catalyst carrier and other fields.

The Chinese utility model patent with publication number CN216831201U provides a slitting device for a hollow cylindrical alumina catalyst carrier production line. The upper end of the workbench of the device is slidably connected with a front baffle and a rear baffle at the front and rear ends, respectively. The front baffle and the rear baffle respectively block and limit the front and rear of the hollow cylindrical alumina catalyst carrier, thereby increasing the stability of the hollow cylindrical alumina catalyst carrier and preventing the hollow cylindrical alumina catalyst carrier from shaking during slitting and affecting the slitting work.

However, the above-mentioned slitting device does not limit the end face of the hollow cylindrical alumina catalyst carrier, which makes the hollow cylindrical alumina catalyst carrier prone to axial sliding during cutting, resulting in low cutting accuracy. In addition, in order to enable the front baffle and the rear baffle to block and limit the cylindrical surfaces of the hollow cylindrical alumina catalyst carriers of different diameters, the front baffle and the rear baffle are straight-faced structures, so that the front baffle and the rear baffle can only make line contact with the cylindrical surface of the hollow cylindrical alumina catalyst carrier. When using this contact method, in order to obtain a better limiting effect, the front baffle and the rear baffle are required to apply a larger clamping force to the hollow cylindrical alumina catalyst carrier, and the larger clamping force is likely to cause the hollow cylindrical alumina catalyst to deform, thereby affecting the quality of the product.

DETAILED DESCRIPTION

The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

Referring to Figures 1, 2 and 6, a catalyst carrier processing and cutting device includes a base plate 1, a feeding hole is opened in the middle of the base plate 1, support frames 2 are fixedly installed on the left and right sides of the base plate 1, a limiting mechanism 3 for supporting the carrier is arranged on the upper part of the base plate 1, and a cutting mechanism 4 for cutting the carrier to a fixed length is arranged between the two support frames 2.

When the hollow cylindrical alumina catalyst carrier needs to be cut, the operator first inserts the hollow cylindrical alumina catalyst carrier into the cutting mechanism 4, and makes the lower end surface of the hollow cylindrical alumina catalyst carrier rest against the limiting mechanism 3, and then uses the cutting mechanism 4 to continuously cut the hollow cylindrical alumina catalyst carrier into fixed lengths.

Referring to Figures 1, 2, 3, 4 and 5, the limiting mechanism 3 includes a supporting assembly 31 arranged on the upper part of the base plate 1, a fixing block 32 is arranged on the supporting assembly 31, a fixing pipe 33 is fixedly installed on the upper part of the fixing block 32, the supporting assembly 31 includes two mounting frames 311 fixedly installed on the left and right sides of the upper part of the base plate 1, the upper parts of the two mounting frames 311 are staggered up and down, a sliding plate 312 is slidably arranged on the mounting frames 311, a notch is provided on one side of the sliding plate 312 close to the middle part of the base plate 1, a sliding plate 313 slidably plugged with the fixing block 32 is fixedly installed inside the notch of the sliding plate 312, and a locking portion 314 is provided inside the sliding plate 312 for fixedly connecting it to the fixing block 32.

Referring to Figures 2, 3 and 4, the locking portion 314 includes a latch 3141 symmetrically arranged front and back inside the sliding plate 312, a ramp block is arranged on the side of the latch 3141 close to the middle of the base plate 1, and an active tension spring is arranged between the two latches 3141 on the same sliding plate 312 away from the middle of the base plate 1.

Referring to Figures 1, 2 and 3, the support assembly 31 also includes a power unit 315 arranged on the upper front side of the base plate 1, and the power unit 315 includes a pushing plate 3151 that is slidable left and right on the upper front side of the base plate 1, and a pushing rod 3152 is fixedly installed on the left side of the pushing plate 3151 corresponding to the left sliding plate 312 and on the right side of the pushing plate 3151 corresponding to the right sliding plate 312. A spiral tension spring is arranged between the left and right sides of the pushing plate 3151 and the sliding plate 312 at the corresponding position, and a No. 1 electric push rod 3153 is fixedly installed on the right side of the front of the base plate 1, and the telescopic section of the No. 1 electric push rod 3153 is fixedly connected to the pushing plate 3151.

In the initial state, the telescopic section of the No. 1 electric push rod 3153 drives the push plate 3151 to be located in the middle of the base plate 1, so that the push plate 3151 pulls the sliding plates 312 on both sides toward the middle of the base plate 1 through the elastic force of the spiral tension springs on both sides, so that the sliding plate 312 drives the sliding plug plate 313 thereon to be inserted into the interior of the fixed block 32, thereby locking the upper and lower positions of the fixed block 32, and at this time, the notch of the sliding plate 312 is sleeved on the outside of the fixed block 32, thereby blocking the forward and backward movement of the fixed block 32, and then limiting the forward and backward movement of the fixed block 32.

When the sliding plate 313 is fully inserted into the interior of the fixed block 32, the sliding plate 312 on the right side drives the left end of the latch 3141 thereon to move to the left side of the fixed block 32, and at the same time, the sliding plate 312 on the left side drives the right end of the latch 3141 thereon to move to the right side of the fixed block 32, and the elastic force of the active tension spring pulls the two latches 3141 inside the same sliding plate 312 closer to each other, and the latch 3141 is pressed against the side of the fixed block 32 through the straight section of the inclined block thereon, thereby locking the left and right positions of the fixed block 32 through the latch 3141 and the sliding plate 312, so that the fixed block 32 drives the fixed pipe 33 to be located at the center position of the upper part of the base plate 1.

Referring to Figures 1, 2 and 5, the limiting mechanism 3 also includes a moving assembly 34 arranged on the outside of the fixed pipe 33, a roller frame 35 is arranged on the moving assembly 34, and the moving assembly 34 includes a No. 1 connecting rod 341 hinged at the lower part of the fixed pipe 33 at equal intervals along the circumference of the fixed pipe 33, and a moving ear seat 342 is arranged on the upper part of the fixed pipe 33 for sliding up and down, and a No. 2 connecting rod 341 corresponding to the No. 1 connecting rod 341 is hinged at equal intervals along the circumference of the fixed pipe 33 on the outside of the moving ear seat 342. 43, the No. 1 connecting rod 341 is rotatably connected to the middle part of the No. 2 connecting rod 343 at the corresponding position, the upper end of the No. 1 connecting rod 341 is hinged with a follower slide 344, the follower slide 344 is slidably connected to the upper side of the roller frame 35 close to the fixed pipe 33, the lower end of the No. 2 connecting rod 343 is hinged to the lower side of the roller frame 35 close to the fixed pipe 33, and a threaded rod 345 is rotatably arranged inside the fixed pipe 33, and the threaded rod 345 is threadedly connected to the movable ear seat 342.

2 and 5 , the limiting mechanism 3 further includes an anti-deformation assembly 36 disposed on the roller frame 35 . The anti-deformation assembly 36 includes a rotating roller 361 which is symmetrical up and down and rotatably disposed on the side of the roller frame 35 away from the fixed pipe 33 . The rotating roller 361 has a structure with a large diameter in the middle and small diameters at both ends. An anti-slip belt 362 is commonly wound around the two rotating rollers 361 on the same roller frame 35 .

When the hollow cylindrical alumina catalyst carrier needs to be cut, the operator sleeves the hollow cylindrical alumina catalyst carrier from top to bottom on the outside of the fixed pipe 33, and at the same time makes the lower end surface of the hollow cylindrical alumina catalyst carrier rest against the upper side of the upper sliding plate 312. At this time, the hollow cylindrical alumina catalyst carrier cover is arranged on the outside of all anti-slip belts 362. Then the operator manually rotates the threaded rod 345, and the threaded rod 345 drives the movable ear seat 342 to move downward, and the movable ear seat 342 drives the upper end of the No. 2 connecting rod 343 to move downward synchronously, so that the No. 2 connecting rod 343 and the No. 1 connecting rod 341 are combined into a scissors-type structure, and then the No. 2 connecting rod 343 and the No. 1 connecting rod 341 drive the roller frame 35 to gradually move away from the fixed pipe 33.

When the roller frame 35 moves, the rotating roller 361 thereon drives the anti-slip belt 362 at the corresponding position to move synchronously. When the anti-slip belt 362 moves to abut against the inner side surface of the hollow columnar alumina catalyst carrier, the anti-slip belt 362 arranged along the circumference of the fixed pipe 33 pushes the hollow columnar alumina catalyst carrier to the coaxial position of the fixed pipe 33, and the inner side surface of the hollow columnar alumina catalyst carrier can be supported by the tight contact of the anti-slip belt 362 to prevent the hollow columnar alumina catalyst carrier from deforming when clamped externally.

It should be noted that the anti-slip belt 362 is made of rubber material, so that when the anti-slip belt 362 is wrapped around the rotating roller 361 with a large diameter in the middle and small diameters at both ends, the anti-slip belt 362 can adapt to the shape of the rotating roller 361, so that when the anti-slip belt 362 contacts the inner side surface of the hollow cylindrical alumina catalyst carrier of different diameters, the anti-slip belt 362 itself can make surface contact with the inner side surface of the hollow cylindrical alumina catalyst carrier, thereby increasing the support range, and the anti-slip belt 362 itself can also absorb the vibration when cutting the hollow cylindrical alumina catalyst carrier through the elasticity of the anti-slip belt 362, thereby improving the cutting effect.

Referring to Figures 1, 6, 7 and 8, the cutting mechanism 4 includes a sliding pipe rack 41 that is slidably arranged between two support plate racks 2 along the up and down directions. The sliding pipe rack 41 is provided with clamping blocks 42 at equal intervals along its circumference. The clamping blocks 42 are slidably connected to the sliding pipe rack 41 along the radial direction. Two fixed ring racks 44 are fixedly installed in the middle part between the two support plate racks 2. The two fixed ring racks 44 are arranged up and down, and a fixed ring 45 is fixedly installed inside the upper fixed ring rack 44.

Referring to Figures 1, 6 and 7, the cutting mechanism 4 also includes a pushing assembly 43 arranged between the two support plate frames 2, and the pushing assembly 43 includes a pushing ring 431 that is slidably arranged between the two support plate frames 2 along the up and down directions. The middle part of the pushing ring 431 is slidably sleeved on the outer side of the sliding pipe frame 41, and a return push spring is arranged between the pushing ring 431 and the sliding pipe frame 41. A side of the clamping block 42 away from the axis of the sliding pipe frame 41 is provided with an inclined surface that gradually inclines from top to bottom away from the axis of the sliding pipe frame 41, and the inner side surface of the pushing ring 431 is slidably connected with the inclined surfaces of all the clamping blocks 42. A No. 2 electric push rod 432 is fixedly installed on the lower side of the top wall of the support plate frame 2 on the right side, and a fixing part 433 for limiting the sliding pipe frame 41 is provided on the support plate frame 2.

Continuing to refer to Figures 1, 6 and 7, the fixed part 433 includes a damping telescopic rod 4331 fixedly installed on the lower side of the top wall of the left support plate frame 2, the telescopic section of the damping telescopic rod 4331 is fixedly connected to the sliding pipe frame 41, and a return tension spring is arranged between the sliding pipe frame 41 and the left support plate frame 2, and an unlocking plate 4332 is fixedly installed at the lower end of the telescopic section of the No. 2 electric push rod 432, and the right side of the unlocking plate 4332 is a pointed structure, and a 匚-shaped part 4333 is arranged on the middle part of the right support plate frame 2 for sliding left and right, and the left side of the 匚-shaped part 4333 is an inclined structure which gradually tilts toward the left side from top to bottom, and a pushing spring is arranged between the 匚-shaped part 4333 and the right support plate frame 2.

When the lower end face of the hollow cylindrical alumina catalyst carrier abuts against the upper side of the upper sliding plate 312, the hollow cylindrical alumina catalyst carrier passes through the two fixed ring frames 44, so that the hollow cylindrical alumina catalyst carrier is inserted into the fixed circular ring 45. After the anti-slip belt 362 supports the hollow cylindrical alumina catalyst carrier in a centering manner, the hollow cylindrical alumina catalyst carrier is located at a coaxial position inside the fixed circular ring 45.

Then, the telescopic section of the No. 2 electric push rod 432 is extended, so that the telescopic section of the No. 2 electric push rod 432 drives the unlocking plate 4332 to move downward. When the lower side of the unlocking plate 4332 abuts against the pushing ring 431, the unlocking plate 4332 pushes the pushing ring 431 to move downward synchronously. At this time, since the tension of the return tension spring is greater than the thrust of the return push spring, the pushing ring 431 moves downward relative to the sliding tube rack 41 and compresses the return push spring, and the tension of the return tension spring pulls the sliding tube rack 41 to remain unchanged.

When the pushing ring 431 moves downward relative to the sliding tube rack 41, the pushing ring 431 pushes the clamping block 42 along the radial direction of the sliding tube rack 41, so that the clamping block 42 approaches the axial position of the sliding tube rack 41, so that the clamping block 42 is pressed against the outer surface of the hollow columnar alumina catalyst carrier, and the positions of the clamping block 42 and the anti-slip belt 362 correspond one by one, and then the hollow columnar alumina catalyst carrier is clamped and supported inside and outside by the clamping block 42 and the anti-slip belt 362, thereby further increasing the stability of the hollow columnar alumina catalyst carrier during cutting.

When the clamping block 42 is pressed against the outer surface of the hollow cylindrical alumina catalyst carrier, the telescopic section of the No. 2 electric push rod 432 continues to be extended to push the pushing ring 431 downward. At this time, since the clamping block 42 can no longer move to the axial position close to the sliding tube rack 41, the pushing ring 431 drives the clamping block 42 and the sliding tube rack 41 to move downward synchronously, and at the same time stretches the return spring, and the clamping force of the clamping block 42 on the hollow cylindrical alumina catalyst carrier causes it to have a tendency to move downward, so that the lower end face of the hollow cylindrical alumina catalyst carrier is pressed against the upper side of the upper sliding plate 312, thereby limiting the axial position of the hollow cylindrical alumina catalyst carrier, further preventing the shaking of the hollow cylindrical alumina catalyst carrier during cutting.

When the sliding tube rack 41 moves downward until it contacts the inclined surface of the inclined surface structure of the 匚-shaped piece 4333, the sliding tube rack 41 pushes the 匚-shaped piece 4333 to the right, so that the 匚-shaped piece 4333 cannot block the sliding tube rack 41 from moving downward, and the 匚-shaped piece 4333 compresses the pushing spring while moving to the right. When the lower end surface of the sliding tube rack 41 abuts against the fixed ring 45, the telescopic section of the No. 2 electric push rod 432 stops extending. At the same time, the sliding tube rack 41 moves to the lower side of the 匚-shaped piece 4333, and then the pushing spring pushes the 匚-shaped piece 4333 to the left to the initial position through its own elastic force, so that the 匚-shaped piece 4333 blocks the sliding tube rack 41 through its lower side, thereby locking the position of the sliding tube rack 41.

Referring to Figures 1, 6, 7 and 8, the cutting mechanism 4 also includes a cutting knife 46 arranged at equal intervals along the circumference of the fixed ring 45 on its lower side, and the cutting knife 46 is slidably connected to the fixed ring 45 in a direction parallel to the tangent of the fixed ring 45. A driving assembly 47 for driving the cutting knife 46 is arranged on the lower fixed ring frame 44. The driving assembly 47 includes an active rotating ring 471 rotatably arranged inside the lower fixed ring frame 44. The active rotating ring 471 is provided with pushing grooves corresponding to the cutting knife 46 at equal intervals along its circumference. The cutting knife 46 slides inside the pushing grooves at the corresponding positions on the active rotating ring 471 through the follower column on the lower side. A No. 3 electric push rod 472 is hinged between the rear left side of the lower fixed ring frame 44 and the active rotating ring 471.

When the hollow cylindrical alumina catalyst carrier is located at the coaxial position of the fixed ring 45, the hollow cylindrical alumina catalyst carrier is also located at the coaxial position inside the active rotating ring 471. When the lower end surface of the sliding tube rack 41 abuts against the fixed ring 45, the telescopic section of the No. 3 electric push rod 472 is extended to drive the active rotating ring 471 to rotate. The active rotating ring 471 moves all the cutting knives 46 through the pushing groove thereon, so that the cutting knives 46 move in a direction parallel to the tangent of the fixed ring 45, and then all the cutting knives 46 jointly perform ring cutting on the hollow cylindrical alumina catalyst carrier, and the blade of the cutting knife 46 does not need to move to the axial position of the hollow cylindrical alumina catalyst carrier to cut off the hollow cylindrical alumina catalyst carrier.

Referring to Figures 2, 3 and 4, the locking portion 314 also includes a T-shaped plate 3142 that is slidably arranged inside the sliding plate 312 along the left and right directions. Straight grooves are provided on the front and rear sides of the longitudinal section of the T-shaped plate 3142. The two straight grooves on the same T-shaped plate 3142 are far away from each other at one end close to the middle of the base plate 1, and the two straight grooves on the same T-shaped plate 3142 are close to each other at one end away from the middle of the base plate 1. The side of the fastener 3141 away from the middle of the base plate 1 slides in the straight groove at the corresponding position of the T-shaped plate 3142 through a raised column, and a support rod 3143 is fixedly installed on the side of the transverse section of the T-shaped plate 3142 away from the middle of the base plate 1.

After the cutting knife 46 cuts off the hollow cylindrical alumina catalyst carrier, the telescopic section of the No. 1 electric push rod 3153 is retracted, so that the No. 1 electric push rod 3153 drives the push plate 3151 to move to the right, and the push plate 3151 pushes the right support rod 3143 to move right synchronously through the right push rod 3152, and the right support rod 3143 drives the right T-shaped plate 3142 to move to the right, so that the T-shaped plate 3142 pulls the two right buckles 3141 away from each other through the linear groove on it. , so that the two snap fasteners 3141 on the right side move to the inside of the sliding plate 312 on the right side, and then the snap fasteners 3141 no longer block the fixed block 32, and then the support rod 3143 on the right side drives the sliding plate 312 on the right side to move to the right side of the hollow columnar alumina catalyst carrier through the T-shaped plate 3142 on the right side and the two snap fasteners 3141 on the right side, so that the hollow columnar alumina catalyst carrier after cutting at the bottom falls onto the sliding plate 312 at the bottom under the action of gravity.

When a section of the hollow cylindrical alumina catalyst carrier falls onto the lower sliding plate 312 after being cut, the telescopic section of the No. 1 electric push rod 3153 is extended to drive the sliding plate 312 on the right to reset, so that the sliding plate 312 on the right is connected and locked on the fixed block 32 again, and then the telescopic section of the No. 1 electric push rod 3153 pushes the sliding plate 312 on the left to move left to the left side of the hollow cylindrical alumina catalyst carrier through the left push rod 3152. The specific principle is the same as above, so that the section of the hollow cylindrical alumina catalyst carrier after being cut falls from the inside of the unloading hole of the base plate 1 to the outside thereof under the action of gravity, thereby completing the unloading, and then the telescopic section of the No. 1 electric push rod 3153 is retracted to drive the push plate 3151 to move to the middle position of the base plate 1 again, so that the sliding plates 312 on both sides are connected and locked on the fixed block 32 again.

Then, the telescopic section of the No. 2 electric push rod 432 is retracted to drive the unlocking plate 4332 to move upward synchronously, so that the unlocking plate 4332 no longer pushes the pushing ring 431 downward. At this time, the sliding tube rack 41 is blocked by the 匚-shaped part 4333 and cannot move, so that the pushing ring 431 moves relatively toward the sliding tube rack 41 under the push of the elastic force of the return push spring, and then the pushing ring 431 drives the clamping block 42 to no longer clamp the hollow cylindrical alumina catalyst carrier. After that, the unlocking plate 4332 moves upward until it contacts the 匚-shaped part 4333, so that the unlocking plate 4332 pushes the 匚-shaped part 4333 to the right through the pointed structure on its right side, so that the 匚-shaped part 4333 no longer blocks the sliding tube rack 41, and then the return tension spring drives the sliding tube rack 41 to slowly move upward to the initial position through its own tension and the slow compression of the damping telescopic rod 4331.

By resetting the clamping block 42 first and then moving the sliding tube rack 41, it is possible to prevent the hollow columnar alumina catalyst carrier from moving upward through the clamping block 42 when the sliding tube rack 41 moves upward, thereby avoiding the distance between the lower end surface of the hollow columnar alumina catalyst carrier and the upper sliding plate 312 being too large, thereby affecting the length of the hollow columnar alumina catalyst carrier when it is cut again.

When the sliding pipe rack 41 moves to the initial position, the telescopic section of the No. 3 electric push rod 472 is retracted to drive the cutting knife 46 to reset, so that the hollow columnar alumina catalyst carrier moves downward again under the action of gravity to rest against the upper side of the upper sliding plate 312, and then the telescopic section of the No. 1 electric push rod 3153 is extended again to press the lower end surface of the hollow columnar alumina catalyst carrier against the upper side of the upper sliding plate 312, thereby continuously cutting the hollow columnar alumina catalyst carrier to a fixed length.

It should be noted that by clamping the inner side of the hollow columnar alumina catalyst carrier through the rotating anti-skid belt 362, it can ensure that the hollow columnar alumina catalyst carrier can move smoothly downward under the action of gravity. At the same time, the anti-skid belt 362 is used to continuously center and limit the hollow columnar alumina catalyst carrier to ensure that the hollow columnar alumina catalyst carrier is always located at the center position of the upper part of the base plate 1.

When cutting the hollow cylindrical alumina catalyst carrier, the present invention also includes the following steps: In the first step, the operator sleeves the hollow cylindrical alumina catalyst carrier from top to bottom on the outside of the fixed pipe 33, and at the same time makes the lower end surface of the hollow cylindrical alumina catalyst carrier abut against the upper side of the upper sliding plate 312, and then the operator manually rotates the threaded rod 345 to drive the anti-slip belt 362 to abut against the inner side surface of the hollow cylindrical alumina catalyst carrier to support it.

In the second step, the telescopic section of the No. 2 electric push rod 432 is extended to drive the unlocking plate 4332 to move downward, so that the unlocking plate 4332 drives the clamping block 42 to press against the outer surface of the hollow cylindrical alumina catalyst carrier through the pushing ring 431, and then the hollow cylindrical alumina catalyst carrier is clamped and supported inside and outside by the clamping block 42 and the anti-slip belt 362, thereby further increasing the stability of the hollow cylindrical alumina catalyst carrier during cutting.

The third step is to continue to extend the telescopic section of the second electric push rod 432, so that the pushing ring 431 drives the lower end surface of the hollow columnar alumina catalyst carrier to press against the upper side of the upper sliding plate 312 through the clamping block 42, thereby axially limiting the hollow columnar alumina catalyst carrier, further preventing the hollow columnar alumina catalyst carrier from shaking during cutting.

The fourth step is to extend the telescopic section of the No. 3 electric push rod 472 to drive the active rotating ring 471 to rotate. The active rotating ring 471 moves all the cutting knives 46 through the pushing groove thereon, so that the cutting knives 46 move in a direction parallel to the tangent of the fixed ring 45, and then all the cutting knives 46 jointly perform ring cutting on the hollow cylindrical alumina catalyst carrier.

In the fifth step, the sliding plates 312 on both sides are pushed in turn by the No. 1 electric push rod 3153, so that a section of the cut hollow cylindrical alumina catalyst carrier falls from the inside of the unloading hole of the base plate 1 to the outside thereof under the action of gravity, thereby completing the unloading, and then the telescopic section of the No. 1 electric push rod 3153 is retracted to drive the push plate 3151 to move to the middle position of the base plate 1 again, so that the sliding plates 312 on both sides are connected and locked on the fixed block 32 again.

The sixth step is to retract the telescopic section of the No. 2 electric push rod 432 to drive the unlocking plate 4332 to move upward, so that the clamping block 42 no longer clamps the hollow cylindrical alumina catalyst carrier. Then the unlocking plate 4332 pushes the 匚-shaped part 4333 to the right, so that the return spring drives the sliding pipe rack 41 to move slowly upward to the initial position through its own tension and the slow compression of the damping telescopic rod 4331.

The seventh step is to retract the telescopic section of the No. 3 electric push rod 472 to drive the cutting knife 46 to reset, so that the hollow columnar alumina catalyst carrier moves downward again under the action of gravity to abut against the upper side of the upper sliding plate 312, and then extend the telescopic section of the No. 1 electric push rod 3153 again to press the lower end face of the hollow columnar alumina catalyst carrier against the upper side of the upper sliding plate 312, thereby continuously cutting the hollow columnar alumina catalyst carrier to a fixed length.
