Description

Solvent-free compound machine capable of automatically cleaning inner wall of cooling roller

Technical Field

The invention relates to the technical field of food bag processing, in particular to a solvent-free compound machine capable of automatically cleaning the inner wall of a cooling roller.

Background

In the production process of the food bag, the solvent-free compounding machine plays a critical role, the equipment coats glue by means of a glue roller, so that food films of two different materials are bonded, then the food films enter a heating and pressing process, in the process, the glue can be activated by heating operation, good bonding effect between the food films is guaranteed, meanwhile, cooling operation can be carried out, the glue can be quickly solidified, a compounded structure is stabilized, and finally the compound food films are orderly rolled up by utilizing a rolling device, so that the whole process is efficient and orderly, and the quality requirement of the food bag can be fully guaranteed.

However, the existing solvent-free compound machine has some problems that firstly, in the cooling process, the circulation mode of the cooling medium in the cooling roller is from one end to the other end, and although the prior art adopts the mode of changing the medium flow to move in a spiral fluid mode, the cooling uniformity is improved to a certain extent, but the defect still exists.

As the spiral fluid continuously flows in the cooling roller and absorbs heat, the capacity of the spiral fluid for absorbing heat gradually decreases, when the spiral fluid moves to the other end of the cooling roller, the capacity of the spiral fluid for absorbing heat is greatly reduced due to the fact that excessive heat is absorbed in the front stage, the condition can directly lead to uneven cooling, for the production of the food bag, uneven cooling can lead to uneven cooling speed of different parts of the food bag composite film, further cause incomplete solidification of glue at certain parts and premature solidification at other parts, further influence the tightness and the integral structural strength of the food bag, in addition, in the cooling process, the two sides of the cooling roller can have allowance, namely, the food film cannot completely cover the cooling roller, and the two sides of the cooling roller are directly contacted with the outside due to the fact that the food film is not covered, so that the heat exchange area of the cooling roller is relatively large, the cooling speed of the two ends of the cooling roller is uneven, the cooling speed of the two ends of the food bag composite film is too high when the food bag composite film passes through the cooling roller, the cooling speed of the middle part is relatively slow, stress difference is generated in the composite film, the composite film is easy to generate stress difference, and the composite film is easy to deform, and the composite film is easy to influence the physical deformation, such as the thermal deformation strength, the tensile strength and the like.

Secondly, when the cooling medium circulates in the cooling roller, the cooling medium absorbs heat, so that the temperature difference is generated between the water inlet and the water outlet, the temperature difference can influence the cooling effect, the temperature difference problem is solved by adopting the push plate to rotate in the prior art, the cooling water in the roller body moves along the axial direction of the roller body and is turned over to be uniformly mixed in the rotating process of the push plate, however, the mode has a plurality of defects, the turning effect of the push plate only carries out reciprocating motion while revolving, the condition that a cleaning dead angle is necessarily formed on a complete circumferential surface is determined, in the circular motion process, the push plate cannot completely cover all areas in the cooling roller, the cooling medium in some areas cannot be sufficiently stirred and mixed, so that the temperature difference in the areas is difficult to be eliminated, meanwhile, when the push plate reciprocates, the two sides at the stroke end are in a motion coincidence phenomenon, the cooling effect on the other side is weaker, and therefore, under the long-term action of the unequal motion mode, impurities are easy to gather in the areas with weaker cooling effect, and dirt is easier to adhere to the inner wall of the cooling roller.

Meanwhile, as the push plate is arranged inside the cooling roller, when the inner wall of the cooling roller is flushed by using the high-pressure water gun and other modes, the cleaning effect of the push plate can be reduced, the push plate can block the water flow path of the high-pressure water gun, so that the water flow can not directly flush certain areas of the inner wall of the cooling roller, dirt is difficult to thoroughly clean, more time is required for cleaning, the downtime of equipment is increased, more time is required for operators to spend on cleaning equipment, and the cleaning frequency and cost of the equipment are further increased.

Therefore, the invention provides a solvent-free compound machine capable of automatically cleaning the inner wall of the cooling roller.

Compared with the prior art, the spiral fluid has the beneficial effects that 1, due to the expansion design of the outer side of the circular thread cavity, the spiral angle of the spiral fluid is gradually enlarged in the flowing process, the spiral fluid starts from a small angle and ends from a large angle, and finally the spiral fluid precisely acts on the middle part of the inner wall of the heat exchange roller, in the process, two spiral fluids impact each other and are fully mixed, when the two spiral fluids collide with each other, the two spiral fluids firstly contact with the middle part of the inner wall of the heat exchange roller and then move reversely with each other under the action of impact mixing force, and under the guidance of the thread grooves, the mixed fluids form a water film structure surrounding the inner wall of the heat exchange roller along the track of the thread grooves and continuously move downwards gradually, so that the spiral structure is formed again, and a more uniform cooling effect is realized.

Unlike the prior art in which spiral fluid absorbs heat gradually from one end to the other end, the bidirectional spiral impact assembly enables two spiral fluids to collide and mix in the middle, so that the problem of cooling capacity reduction caused by excessive heat absorption of the fluids is effectively avoided, and the middle impact mixing ensures that the cooling medium maintains higher heat exchange efficiency in the whole cooling roller, thereby improving cooling uniformity.

Through middle impact mixing and reverse rotation design, the problem of low self heat exchange efficiency caused by heat absorption of the cooling medium in the flowing process is avoided, and more uniform distribution and more efficient heat exchange of the cooling medium in the whole cooling roller are realized through strong mixing and guiding, so that the cooling uniformity is remarkably improved.

Under the continuous flushing of the spiral fluid, the inner wall of the heat exchange roller can be cleaned to a certain extent, and the adhesion of dirt and impurities is reduced.

The spiral fluid is contacted with the two sides of the heat exchange roller at last, and the sufficient mixing and heat exchange are realized in the flowing process, so that the temperature gradient of the two sides and the middle of the heat exchange roller can be effectively balanced, and the situation that the food composite film has a raised edge is reduced.

Compared with the prior art, the fluid vortex generating assembly not only realizes the cleaning effect without dead angles, but also has the effect of mixing cooling medium, thereby ensuring that the temperature gradient can not generate great difference.

The screwing directions of the fixed fin and the sliding fin are opposite, and the thread grooves are also opposite, so that the fixed fin and the sliding fin are easier to drive in the process of reversing movement of spiral fluid, and the movement of the fluid can drive the fixed fin and the sliding fin to rotate.

Specifically, the operator starts through external controller electrical control water tank 27, refrigeration component, equipment power and external drive equipment, and external drive equipment will drive first unreel roller, second unreel roller, tension roller, wind-up roll, heating roller and heat transfer roller 13 rotation this moment, and the material on the second unreel roller is in the same place through tension roller and glue film complex on the rubber roll and is formed combined material three simultaneously under tension roller's rotation, and combined material one and combined material three are heated after the heating roller and are formed combined material four, and finally combined material four is finally rolled up to the wind-up roll after the heat transfer roller 13 cooling.

In this process, after the water pump 28 is started, the cooling water stored in the water pump is kept in a low temperature state under the action of the refrigerating element, and then the cooling water is led into the inner space of the spiral ring 21 along the first water distribution pipe 29, and a closed loop cooling water circulation system is formed due to the connection of the discharge pipe 26 and the second water distribution pipe 210, so that the cooling water can only continue to flow through the circular thread cavity 24 when entering the heat exchange roller 13, and the circular thread cavity 24 causes a strong spiral flow effect when the cooling water flows.

Specifically, the round thread cavity 24 utilizes the fluid dynamics principle, one side of the round thread cavity near the center of the heat exchange roller 13 is gradually expanded to form a small-angle and large-angle flow channel shape, the design ensures that when cooling water flows through the round thread cavity 24, the speed is accelerated, the flowing direction is continuously changed, so that strong spiral fluid is generated, two spiral fluids with opposite directions are formed because the inside of the round thread cavity 24 on two sides simultaneously enters the cooling water, the two spiral fluids meet in the middle part of the inner wall of the heat exchange roller 13 and collide, and the collision process has multiple benefits that firstly, the excessive heat absorption of the cooling water on a single path is avoided, and the overall cooling efficiency of the cooling water is maintained; and secondly, the collided cooling water is fully mixed, so that the temperature is more uniform, and the cooling effect is further improved.

The two fluid bodies after collision have opposite movement trend due to mutual impact and mixing, and still keep certain spiral movement characteristics while interacting, under the action of fluid dynamics and the influence of centrifugal force of continuous rotation of the heat exchange roller 13, the fluid bodies can be subjected to strong guiding action when contacting the thread grooves 25, so that spiral fluid bodies moving reversely along the thread direction of the thread grooves 25 are formed, the process not only enhances the heat exchange efficiency of cooling water and the inner wall of the heat exchange roller 13, but also enables the cooling water to be more uniformly distributed on the surface of the inner wall of the whole heat exchange roller 13, and in addition, the cooling water with the spiral movement trend can play a certain role in cleaning the inner wall of the heat exchange roller 13.

In addition, the reverse spiral fluid can ensure that hotter cooling water can finally contact and cool two sides of the heat exchange roller 13 in the flowing process, so that the temperature distribution inside the heat exchange roller 13 is effectively balanced, in addition, as the part of fluid continuously flows inside the heat exchange roller 13, the kinetic energy of the fluid gradually disappears and finally moves to the bottom of the inner wall of the heat exchange roller 13, at the moment, the water pump 28 recovers the cooling water which has absorbed a certain amount of heat through the water distribution pipe II 210 again, and sends the cooling water into the refrigerating element for cooling again, so that the recycling of the cooling water is realized.

In the second embodiment, as shown in fig. 5 and 9, a fluid vortex generating assembly 3 for cleaning the inner wall of the cooling roller is disposed on the outer side of the discharge pipe 26, the fluid vortex generating assembly 3 includes two limiting convex rings 31, the two limiting convex rings 31 are symmetrically and fixedly connected to the outer wall of the discharge pipe 26, the outer surfaces of the limiting convex rings 31 are rotationally connected with rotating rings 32, a plurality of fixing fins 33 are fixedly connected to the outer wall of the limiting convex rings 31 in an annular equidistant arrangement, and the rotating directions of the fixing fins 33 on the two sides are opposite.

Referring to fig. 9, the fluid vortex generating assembly 3 further includes a plurality of sliding chambers 34, the plurality of sliding chambers 34 are all arranged at equal intervals in an annular shape and are arranged on the outer surface of the rotating ring 32, the telescopic rods 35 are fixedly connected inside the sliding chambers 34, the sliding blocks 36 are fixedly connected with the output ends of the telescopic rods 35, the sliding blocks 36 are all connected inside the sliding chambers 34 in a sliding manner, the sliding fins 37 are fixedly connected to the outer surfaces of the sliding blocks 36, the sliding fins 37 on two sides are oppositely arranged in screwing direction, the fixing rods 39 are fixedly connected to one sides of the sliding blocks 36 far away from the telescopic rods 35, the limiting sliding rails 38 are symmetrically and fixedly connected to the outer surfaces of the discharge pipes 26, one sides of the limiting sliding rails 38 close to the limiting convex rings 31 are obliquely arranged, the inside of the limiting sliding rails 38 are hollow, one sides of the fixing rods 39 far away from the sliding blocks 36 are rotatably connected with the ball shafts 310, one sides of the ball shafts 310 far away from the fixing rods 39 are rotatably connected with the rotating seats 311, the inside the rotating seats 311 are rotatably connected with the bidirectional conical rods 312, two sides of the bidirectional conical rods 312 are gradually contracted, and the bidirectional conical rods 312 are slidably connected to the outer surfaces of the limiting sliding rails 38.

Specifically, in the first embodiment, after the two spiral fluids form the reverse spiral structure under the guidance of the thread groove 25, they not only promote the heat exchange between the cooling water and the inner wall of the heat exchange roller 13, but also additionally trigger the cleaning mechanism of the fluid vortex generating assembly 3.

Since the screwing direction of the fixed fin 33 and the sliding fin 37 is matched with the track of the screw groove 25, the impact force of the reverse spiral fluid and the self-contained rotational momentum are effectively converted into mechanical driving force, which first causes the fixed fin 33 to start rotating, thereby transmitting the rotational motion to the rest of the parts on the surface of the rotating ring 32 through the rotating ring 32.

Along with the rotation of the fixed fin 33, the rotating ring 32 synchronously rotates on the limiting convex ring 31, in this process, the telescopic rod 35, the sliding block 36 and the sliding fin 37 in the sliding chamber 34 also enter into a working state, the rotation of the sliding fin 37 not only responds to the impact of fluid, but also further drives the bidirectional conical rod 312 to move through the ball shaft 310 and the rotating seat 311 due to the fixed connection with the fixed rod 39, and it is worth noting that the two sides of the bidirectional conical rod 312 are designed to be in a tapered shape, and the design ensures that the bidirectional conical rod can be closely attached to the inclined surface of the limiting sliding rail 38 when sliding along the limiting sliding rail 38, so that the inner wall of the heat exchange roller 13 is comprehensively and uniformly cleaned.

It is noted that the compound motion of the sliding fin 37, which is a key element in the cleaning mechanism, not only rotates with the sliding block 36 in the sliding chamber 34, but also slides back and forth laterally due to the limiting action of the limiting slide rail 38, has a unique hydrodynamic effect in that, as the sliding fin 37 rotates and moves laterally, the surrounding fluid is agitated to form deflected fluid vortices, which are generated due to the shearing action of the sliding fin 37 on the fluid during rotation and the relative motion of the fluid between the surface of the sliding fin 37 and the inner space of the sliding chamber 34, and the forming position and angle of each fluid vortex are different from each other because the sliding block 36 and the sliding fin 37 are always in a laterally dynamic moving state during rotation, and this diversity enhances the stripping capability of the fluid vortex on the dirt on the inner wall of the cooling roller.

The fluid vortices have a tendency to turn over because they are subjected to various forces during formation, firstly, they are subjected to centrifugal forces generated by the rotation of the sliding fins 37, which promote outward diffusion of the fluid vortices, secondly they are also subjected to viscous forces of the surrounding fluid, which cause deformation and turning over of the fluid vortices during diffusion, and finally they peel off and carry away dirt on the inner wall in a powerful manner when they touch the inner wall of the heat exchanger roll 13, which tendency not only enhances the cleaning ability of the fluid vortices, but also promotes adequate mixing of the cooling water inside the cooling roll.

Therefore, the rotation of the fixed fin 33 not only directly drives the movement of the cleaning system, but also enhances the formation and cleaning effect of fluid vortex by generating rotational momentum, and the compound movement of the sliding fin 37 achieves the efficient cleaning of the inner wall of the heat exchange roller 13 by generating deflected fluid vortex, which not only peels off and takes away dirt on the inner wall in the process of overturning, but also promotes the thorough mixing of cooling water inside the heat exchange roller 13, thereby improving the cooling efficiency.
