Example 1

Referring to Fig. 1 to Fig. 3 and Fig. 10, the first embodiment of the utility model provides a plastic protective net leveling machine, which includes a base 100 for supporting the entire device to make the entire device more stable when in use, the base 100 is provided with two groups of brackets 200 arranged on the base 100, used to support the leveling component 500 to flatten the folds of the polypropylene plastic biaxially stretched net, a support plate 300 arranged between the bases 100, used to cooperate with the leveling component 500 to flatten the folds of the polypropylene plastic biaxially stretched net, and a standing board 400 arranged on the base 100, used for people to stand, conveniently operate the leveling component 500, and improve the safety performance during use;

The flattening component 500 may include a power component 501 arranged on the bracket 200, which is used to generate power for the entire device to operate; an angle steel 502 arranged on the power component 501, which is used to cooperate with the support plate 300 to flatten the wrinkles of the polypropylene plastic biaxially stretched net. The bent part of the angle steel 502 is fixedly connected to the output end of the power component upward, and the two sides of the angle steel 502 are provided with flat angles downward to increase the contact area with the polypropylene plastic biaxially stretched net and avoid damaging the polypropylene plastic biaxially stretched net during flattening; a pulling component 503 arranged below the power component 501, which is used to pull the polypropylene plastic biaxially stretched net, and pull the wrinkles of the polypropylene plastic biaxially stretched net to the bottom of the angle steel 502 for flattening as the power component 501 moves.

The power assembly 501 includes a hydraulic pusher 501a disposed on the bracket 200, which is the power source of the entire device and is used to output the power to operate the entire device. A control rod is disposed on the side of the hydraulic pusher 501a close to the station board 400 to facilitate personnel to control the movement of the hydraulic pusher 501a, a connecting rod 501b disposed on the hydraulic pusher 501a, which is used to drive the movable sleeve 501c to move up and down with the movement of the hydraulic pusher 501a, and a connecting rod 501b disposed at both ends of the connecting rod 501b and slidably disposed on the bracket 200. The movable sleeve 501c on the bracket 200 is used to move on the bracket 200 and output power to the transmission member 501e. The limit block 501d arranged on the bracket 200 and abutting against the upper part of the movable sleeve 501c is used to limit the position of the movable sleeve 501c to avoid the problem of over-extension of the transmission member 501e causing failure of transmission. The transmission member 501e arranged below the movable sleeve 501c is used to convert the falling force of the movable sleeve 501c into a lateral force, so that the pulling component 503 moves back and forth on the base 100.

Furthermore, the transmission member 501e includes a pressure rod 501e-1 arranged under the movable sleeve 501c, a limiting groove 501e-2 opened at the end of the pressure rod 501e-1 away from the movable sleeve 501c, which is used to limit the rotation direction of the movable rod 501e-3 to the side close to the locking pulling assembly 503, the movable rod 501e-3 arranged in the limiting groove 501e-2, and a pushing rod 501e-4 arranged at the end of the movable rod 501e-3 away from the pressure rod 501e-1. The pressure rod 501e-1 is used to press the movable rod 501e-3 downward through the movement of the movable sleeve 501c, so that the lower end of the movable rod 501e-3 moves toward the side close to the pulling assembly 503, driving the pushing rod 501e-4 to make the entire pulling assembly 503 start to move.

During use, when the polypropylene plastic biaxially stretched net needs to be flattened, the device is placed on flat ground, and the staff places the polypropylene plastic biaxially stretched net to be flattened on the side of the device away from the pulling component 503. At this time, the staff pulls one end of the polypropylene plastic biaxially stretched net through the stand plate 400 and the support plate 300, and pulls it under the pulling component 503. At this time, the staff stands on the stand plate 400 and controls the hydraulic push slide 501a to fall through the control rod. At this time, the movable sleeve 501c squeezes the pressure rod 501e-1 downward, and the movable rod 501e-3 drives the push rod 501e-3 to push the push rod 501e-3. Rod 501e-4 controls the movement of the pulling component 503. At this time, the pulling component 503 grabs the polypropylene plastic biaxially stretched net. As the hydraulic push slide 501a falls, the pulling component 503 pulls the polypropylene plastic biaxially stretched net to the side away from the hydraulic push slide 501a. When the pulling component 503 moves into place, the angle steel 502 just presses the folds of the polypropylene plastic biaxially stretched net. After pressing for a period of time, the hydraulic push slide 501a is controlled to move up. At this time, the pulling component 503 releases the polypropylene plastic biaxially stretched net and moves quickly toward the direction close to the hydraulic push slide 501a.

Example 2

1 to 7 and 9, a second embodiment of the present utility model is shown, which is different from the first embodiment in that the hydraulic push slide 501a moves a very small distance to allow the pulling teeth 503e-4 to pull the polypropylene plastic biaxially stretched net a large distance.

Compared with the first embodiment, the pulling assembly 503 further includes a pneumatic member 503a disposed at the end of the push rod 501e-4 away from the movable rod 501e-3, a moving rod 503b disposed at the output end of the pneumatic member 503a for controlling the movement of the movable rod 501e-3 to balance the pressure, and used to move with the movement of the pneumatic member 503a, a vertical rod 503c disposed at the end of the moving rod 503b away from the pneumatic member 503a, which plays a connecting role, and a pull rod 503d disposed at the end of the vertical rod 503c away from the moving rod 503b, used to move the vertical rod 503c through the vertical rod 503c. 3c is connected to the movable rod 501e-3, synchronizes the movement of the movable rod 501e-3, and the elastic member 503e arranged at the end of the pull rod 503d away from the vertical rod 503c is used to control the clamping of the polypropylene plastic biaxially stretched net and pull the polypropylene plastic biaxially stretched net. The movable groove 503f arranged in the base 100 and cooperating with the elastic member 503e is used to enable the elastic member 503e to loosen and clamp the polypropylene plastic biaxially stretched net as the hydraulic push slide 501a rises and falls, so as to facilitate continuous operation and improve work efficiency.

Among them, the pneumatic part 503a includes a first movable plug 503a-1 arranged at one end of the push rod 501e-4 away from the movable rod 501e-3, a first air cavity 503a-2 arranged in the base 100 and matching the first movable plug 503a-1, a second air cavity 503a-3 opened in the base 100 and connected with the first air cavity 503a-2, and a second movable plug 503a-4 arranged in the second air cavity 503a-3. The first movable plug 503a-1 and the second movable plug 503a-4 are both cylindrical, and the diameter of the first movable plug 503a-1 is much larger than the diameter of the second movable plug 503a-4. When the first movable plug 503a-1 moves a shorter distance, the second movable plug 503a-4 can move a longer distance.

Among them, one end of the movable rod 501e-3 is fixedly connected to the second movable plug 503a-4, the movable rod 501e-3 moves and passes through the second air cavity 503a-3 to the outside of the base 100, and the second movable plug 503a-4 moves quickly through the first movable plug 503a-1, driving the movable rod 501e-3 to move quickly outward, so that the elastic member 503e pulls the polypropylene plastic biaxially stretched net to move quickly outward.

The elastic member 503e includes a first pull plate 503e-1 disposed at one end of the pull rod 503d away from the vertical rod 503c, the first pull plate 503e-1 is slidably disposed on the base 100 and is used to pull the polypropylene plastic biaxially stretched net, a spring 503e-2 disposed on the first pull plate 503e-1, and a second pull plate 503e-3 disposed on one end of the spring 503e-2 away from the first pull plate 503e-1, and a second pull plate 503e-3 disposed on the second pull plate 503e-3. The pulling tooth 503e-4 on the pulling plate 503e-3 is used to pull the polypropylene plastic biaxially stretched net. The pulling tooth 503e-4 moves and passes through the first pulling plate 503e-1 and the connecting column 503e-5 set on the lower surface of the second pulling plate 503e-3, and is used to connect the movable block 503e-6. The movable block 503e-6 set under the connecting column 503e-5 is used to move in the movable groove 503f to guide the first pulling plate 503e-1 to move back and forth on the base 100.

Among them, the movable block 503e-6 is movably arranged in the movable groove 503f, the connecting column 503e-5 is movable and passes through the first pull plate 503e-1 and the base 100, and a movable groove 600 cooperating with the connecting column 503e-5 is opened on the base 100 for the movement of the connecting column 503e-5, and the movable groove 600 passes through the movable groove 503f.

During use, when it is necessary to flatten the polypropylene plastic biaxially stretched net, the device is placed on flat ground, and the staff places the polypropylene plastic biaxially stretched net to be flattened on the side of the device away from the pulling component 503. At this time, the staff pulls one end of the polypropylene plastic biaxially stretched net through the station plate 400 and the support plate 300, and pulls it to the bottom of the first pull plate 503e-1. At this time, with the fall of the hydraulic push slide 501a, the push rod 501e-4 drives the movable plug to move to the side close to the second air cavity 503a-3. At this time, the second movable plug 503a-4 drives the movable rod 501e-3 to move outward. At this time, the pull rod 503d moves the first pull plate 503e-1 to the side away from the hydraulic thruster. At this time, the first pull plate 503e-1 pulls the connecting column 503e-5. At this time, the movable block 503e-6 enters the lower part of the movable groove 503f under the action of gravity and tension. At this time, the second pull plate 503 e-3 is pressed down with the movement of the movable block 503e-6. At this time, the spring 503e-2 contracts and accumulates force, and the pulling tooth 503e-4 moves downward to pull the polypropylene plastic biaxially stretched net. At this time, as the first movable plug 503a-1 continues to move, the pulling tooth 503e-4 pulls the polypropylene plastic biaxially stretched net quickly to the side away from the hydraulic push slide 501a. When the first pull plate 503e-1 moves into place, the angle steel 502 just presses the polypropylene plastic. The folds of the biaxially stretched net of the material are pressed for a period of time, and then the hydraulic push slide 501a is controlled to move upward. At this time, the pulling tooth 503e-4 loosens the polypropylene plastic biaxially stretched net, and the spring 503e-2 is released. At this time, the movable block 503e-6 enters the upper part of the movable groove 503f. As the hydraulic push slide 501a moves upward, the first pull plate 503e-1 drives the second pull plate 503e-3 to move quickly in the direction close to the hydraulic push slide 501a for the next flattening.

The remaining structures are the same as those of Example 1.

Example 3

4, and FIG. 6-FIG. 8, a third embodiment of the present utility model is shown, which is different from the second embodiment in that the pulling of the polypropylene plastic biaxially stretched net and the flattening action can be performed continuously.

Compared with the second embodiment, the movable groove 503f further comprises a first transverse groove 503f-1 provided in the base 100 and a second transverse groove 503f-2 provided in the base 100. The length of the second transverse groove 503f-2 is equal to the distance between two wrinkles on the biaxially stretched polypropylene plastic mesh, so that the pull teeth 503e-4 can pull the wrinkles of the biaxially stretched polypropylene plastic mesh to the bottom of the angle steel 502 each time. The length of the first transverse groove 503f-1 is equal to the distance between two wrinkles on the biaxially stretched polypropylene plastic mesh. In the second transverse groove 503f-2, the first inclined groove 503f-3 and the second inclined groove 503f-4 are opened between the first transverse groove 503f-1 and the second transverse groove 503f-2. The first inclined groove 503f-3 is used to guide the movable block 503e-6 from the first transverse groove 503f-1 into the second transverse groove 503f-2, and the second inclined groove 503f-4 is used to guide the movable block 503e-6 from the second transverse groove 503f-2 into the first transverse groove 503f-1.

Among them, the first transverse groove 503f-1 and the second transverse groove 503f-2 are parallel and centrally arranged, the first inclined groove 503f-3 and the second inclined groove 503f-4 are respectively located at the two ends of the first transverse groove 503f-1, the cross-section of the movable groove 503f is an inverted trapezoid, and the connecting part between the second inclined groove 503f-4 and the first transverse groove 503f-1 is provided with an oblique edge, which is directed upward to facilitate guiding the movable block 503e-6 from the second inclined groove 503f-4 into the first transverse groove 503f-1.

During use, when the polypropylene plastic biaxially stretched net needs to be flattened, the hydraulic push slide 501a is controlled to move downward, and the first movable plug 503a-1 moves to the side close to the second movable plug 503a-4. At this time, the second movable plug 503a-4 drives the pull rod 503d to pull the first pull plate 503e-1. The initial position of the movable block 503e-6 is located at the interface between the first transverse groove 503f-1 and the first inclined groove 503f-3. Under the action of gravity, the movable block 503e-6 is located at a larger position in the first inclined groove 503f-3. At this time, the movable block 503e-6 is located at the interface between the first transverse groove 503f-1 and the first inclined groove 503f-3. Under the pulling, the movable block 503e-6 enters the first inclined groove 503f-3. At this time, as the movable block 503e-6 moves in the first inclined groove 503f-3, the second pull plate 503e-3 begins to move downward. At this time, the spring 503e-2 contracts and accumulates force, and the pulling tooth 503e-4 moves down to pull the polypropylene plastic biaxially stretched net. When the movable block 503e-6 enters the second transverse groove 503f-2 from the first inclined groove 503f-3, the second pull plate 503e-3 falls into place. At this time, as the pull rod 503d continues to move, the pulling tooth 503e-4 pulls the polypropylene plastic biaxially stretched net to drive the first pull The plate 503e-1 moves in the direction away from the hydraulic push slide 501a. When the movable block 503e-6 moves to the mouth of the second inclined groove 503f-4, as the pull tooth 503e-4 continues to move, the movable block 503e-6 enters the second inclined groove 503f-4. At this time, as the movable block 503e-6 moves in the second inclined groove 503f-4, the spring 503e-2 is gradually released. When the movable block 503e-6 moves to the interface between the second inclined groove 503f-4 and the first transverse groove 503f-1, the spring 503e-2 is completely released, and the pull tooth 503e-4 is retracted, leaving the polypropylene plastic double When the folds of the polypropylene plastic biaxially stretched net are flattened for a period of time, the hydraulic pusher 501a is controlled to move upward, and the first movable plug 503a-1 retracts, and the second movable plug 503a-4 drives the pull rod 503d to move back. At this time, the pull rod 503d drives the first pull plate 503e-1 and the second pull plate 503e-3 to move back until the first pull plate 503e-1 returns to its original position. At this time, the next flattening action can be performed without the staff having to pull the polypropylene plastic biaxially stretched net again, which saves working time and improves work efficiency.

The remaining structure is the same as that of Example 2.
