Description

Technical Field

[0001] This utility model relates to the technical field of cooling equipment for plastic products, and in particular to a cooling pool for plastic products. Background Technology

[0002] Plastic pollution is a global environmental problem. Plastics are not easily degraded and may take hundreds of years to decompose in the natural environment, causing long-term impacts on soil, water sources and ecosystems. Therefore, recycling plastics from waste is beneficial to reducing plastic pollution to the environment.

[0003] In the process of recycling and reusing plastic waste, it needs to go through sorting, crushing, melting, and extrusion molding. The extrusion molding process requires an extruder, which melts the crushed plastic fragments and then extrudes them from the extrusion nozzle to form thin strips. The strips are then granulated in subsequent processes to make the thin strips into smaller granules. Granular recycled plastic products are beneficial for subsequent product reprocessing.

[0004] After the extruder extrudes the material into shape, the temperature of the material is high at this time. If the extruded material is not cooled in time, it is easy for the material to undergo excessive deformation, which will affect the quality of subsequent products. Utility Model Content

[0005] In order to cool the extruded strip from the extruder so that the strip can be quickly shaped, this application provides a cooling tank for plastic products.

[0006] This application provides a cooling tank for plastic products, employing the following technical solution:

[0007] A cooling tank for plastic products, including

[0008] A water-cooled pool, with an inlet at one end and an outlet at the other, the inlet being used to receive the extrusion port of the extruder, and the interior of the water-cooled pool being used to hold cooling water.

[0009] A water filter tank is located outside the outlet end of the water cooling tank and is independent of the water cooling tank. Both the water cooling tank and the water filter tank are placed along the material conveying direction.

[0010] The water-cooling pool is equipped with a guide roller assembly, which is submerged in cooling water and used to guide the material strips to be transported in the cooling water.

[0011] The water filter tank is equipped with a water filter roller assembly, which is higher than the top end face of the water filter tank. The water filter roller assembly is used to raise and convey the material strips transported from the water cooling tank.

[0012] Furthermore, the guide roller assembly includes at least one horizontally placed guide roller, both ends of which are rotatably connected to the inner wall of the water-cooling pool. The guide roller is used to press the material strip into the cooling water.

[0013] Furthermore, the outer wall of the guide roller is provided with a plurality of guide grooves spaced apart along its own length direction. The opening width of the guide grooves is slightly larger than the outer diameter of the material strip. The guide grooves are opened circumferentially along the guide roller, and the number of guide grooves is used to correspond to the number of material strips.

[0014] Furthermore, the filter roller assembly includes at least one filter roller, which includes a housing and a suction cylinder arranged coaxially. A gap is left between the housing and the suction cylinder. The housing is fixed to the top of the filter tank, and the suction cylinder is rotatably connected inside the housing. The top and bottom of the housing are respectively provided with a communicating opening and a drainage groove. The outer wall of the suction cylinder is covered with a water-absorbing element, and the top part of the suction cylinder extends out from the opening to allow the water-absorbing element to contact the material strip.

[0015] Furthermore, the inner wall of the outer shell is provided with a water-squeezing block, and the side wall of the water-squeezing block facing the water-absorbing cylinder is the water-squeezing surface. Along the rotation direction of the water-absorbing cylinder, the distance between the water-squeezing surface and the outer wall of the water-absorbing cylinder gradually decreases.

[0016] Furthermore, the squeezing block is slidably connected to the outer shell along the radial direction of the suction cylinder. The inner wall of the outer shell is provided with a sliding groove for the squeezing block to slide. An elastic element is provided in the sliding groove, and the two ends of the elastic element abut against the squeezing block and the outer shell, respectively.

[0017] Furthermore, the inlet end of the water-cooled pool is provided with a horizontal receiving roller for receiving the strip extruded from the extruder.

[0018] Furthermore, a horizontal transition roller is provided between the water cooling pool and the water filtration pool. The transition roller is located above the water cooling pool and is used to smoothly transport the material strip from the water cooling pool to the water filtration pool.

[0019] In summary, this application has the following beneficial effects:

[0020] By using a water-cooling tank filled with cooling water, the extruded strip enters the water-cooling tank under the guidance of the guide rollers. The cooling water in the tank can cool and shape the extruded strip in time, reducing its deformation. After cooling and shaping, the strip is lifted by the filter rollers and conveyed to the top of the filter tank for filtration. During the conveying process, the water-absorbing components on the suction cylinder come into contact with the strip and absorb the moisture on the surface of the strip, further removing the moisture and facilitating subsequent operations.

The following description presents a preferred embodiment among several possible embodiments of this application, intended to provide a basic understanding of the application, but not intended to identify key or decisive elements of the application or to limit the scope of protection sought.

The content protected by this application does not involve any improvement to the internal structure and method.

[0029] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] An embodiment of this application provides a cooling tank for plastic products, referring to... Figure 1 The plastic product cooling tank includes a water cooling tank 1 and a water filtration tank 2. The water cooling tank 1 is used to cool and shape the material strip 3, while the water filtration tank 2 is used to remove moisture from the surface of the cooled material strip 3. After removing the surface moisture, the material strip 3 is easier to carry out subsequent operations or processes.

[0031] Both the water-cooling tank 1 and the filter tank 2 are rectangular in shape. They are independent tanks and are placed along the conveying direction of the material strip 3. One end of the water-cooling tank 1 along its length is the inlet end 11, and the other end is the outlet end 12. The inlet end 11 of the water-cooling tank 1 is placed corresponding to the extrusion port of the extruder, and can receive and cool the material strip 3 extruded from the extruder.

[0032] The filter tank 2 is placed at the outlet end 12 of the water-cooled tank 1, and can receive the material strips 3 from the water-cooled tank 1 and perform water removal operation on the material strips 3. In other embodiments of this application, the water-cooled tank 1 and the filter tank 2 may be the same tank, but a partition plate is used to separate the water-cooled tank 1 and the filter tank 2 into two independent cavity spaces.

[0033] The water-cooling tank 1 is filled with cooling water 13, which can be tap water at room temperature or slightly below room temperature. A horizontal receiving roller 14 is fixed to the top of the inlet end 11 of the water-cooling tank 1. The length direction of the receiving roller 14 is perpendicular to the conveying direction of the material strip 3, and both ends of the receiving roller 14 can be rotatably connected to the water-cooling tank 1 via support frames. The receiving roller 14 can receive the material strip 3 extruded from the extruder and guide it into the water-cooling tank 1, preventing the material strip 3 from contacting the tank body or other objects before entering the cooling water 13, thus reducing deformation caused by collision.

[0034] Reference Figure 1 and Figure 2 A guide roller assembly is installed inside the water-cooling tank 1, and the guide roller assembly is submerged in cooling water 13. The guide roller assembly includes at least one horizontally placed guide pressure roller 15. In this embodiment, two guide pressure rollers 15 are provided, and the two guide pressure rollers 15 are placed at intervals along the conveying direction of the material strip 3. Both guide pressure rollers 15 are submerged in cooling water 13, and both guide pressure rollers 15 are rotatably connected to the inner wall of the water-cooling tank 1. In other embodiments of this application, the number of guide rollers can be increased or decreased according to the actual length of the water-cooling tank 1.

[0035] During use, two guide rollers 15 jointly press the strip 3 down into the cooling water 13, allowing the strip 3 to be continuously cooled in the cooling water 13 under the action of the guide rollers 15, which is beneficial for the rapid shaping of the strip 3. To prevent the strip 3 from tangling together during cooling, multiple guide grooves 151 are spaced apart along the length of the outer wall of the guide roller 15. The guide grooves 151 are opened circumferentially along the guide roller 15, and the number of guide grooves 151 corresponds to the number of strips 3 extruded. The opening 511 of the guide groove 151 is slightly wider than the outer diameter of the strip 3, allowing the strip 3 to be embedded in the guide groove 151 for conveying. While the strip 3 is being cooled, the guide grooves 151 also play a shaping role for the strip 3, reducing the deformation of the strip 3 during conveying.

[0036] Reference Figure 1 and Figure 3 A horizontal transition roller 4 is installed between the water cooling tank 1 and the water filtration tank 2. The transition roller 4 is located above the water cooling tank 1 and can be rotatably connected to the top of the water cooling tank 1 or the water filtration tank 2 via a support frame. The transition roller 4 can receive the material strips 3 conveyed from the water cooling tank 1 to the water filtration tank 2, preventing the material strips 3 from bumping or colliding during conveying.

[0037] The water filter tank 2 is equipped with a set of 5 filter rollers, each set including at least one filter roller 5. In this embodiment, two filter rollers 5 are provided and are spaced apart along the conveying direction of the material bar 3. In other embodiments of this application, the number of filter rollers 5 can be increased or decreased according to the actual length of the water cooling tank 1. Both filter rollers 5 are higher than the top end face of the water filter tank 2, and the filter rollers 5 can also be rotatably connected to the water filter tank 2 via a support frame.

[0038] The two filter rollers 5 can rotate synchronously through belt drive, and one end of one of the filter rollers 5 is equipped with a drive motor. The output shaft of the drive motor is coaxially fixed with the end of the filter roller 5. The filter roller 5 can be actively rotated by the drive motor, so that the filter roller 5 can be raised and transport the material strip 3 transported from the water cooling pool 1. When the material strip 3 enters the filter pool 2, the water on its surface can fall into the filter pool 2 by its own gravity.

[0039] Specifically, the filter roller 5 includes a coaxially arranged outer shell 51 and a water suction cylinder 52. The outer shell 51 wraps around the water suction cylinder 52, and a gap is left between the outer shell 51 and the water suction cylinder 52. The outer shell 51 is fixed to the top of the filter tank 2, and the water suction cylinder 52 is rotatably connected inside the outer shell 51. One end of the water suction cylinder 52 is connected to the output shaft of the drive motor. The top and bottom of the outer shell 51 are respectively provided with a communicating opening 511 and a drainage groove 512. The outer wall of the water suction cylinder 52 is covered with a water-absorbing element 53. In this embodiment, the water-absorbing element 53 can be a water-absorbing sponge. The top part of the water suction cylinder 52 extends from the opening 511, so that the water-absorbing element 53 can contact the material strip 3 when the filter roller 5 is conveying the material strip 3. At this time, the water-absorbing element 53 can actively absorb excess water on the material strip 3 and accelerate the removal of water from the surface of the material strip 3.

[0040] Furthermore, a water-squeezing block 54 is provided on the inner wall of the outer shell 51. The side wall of the water-squeezing block 54 facing the water-absorbing cylinder 52 is the water-squeezing surface 541. Along the rotation direction of the water-absorbing cylinder 52, the distance between the water-squeezing surface 541 and the outer wall of the water-absorbing cylinder 52 gradually decreases.

[0041] During the absorption of water, the absorbent component 53 gradually expands. As it rotates with the absorbent cylinder 52, the expanded absorbent component 53 comes into contact with the squeezing surface 541. Because the distance between the squeezing surface 541 and the outer wall of the absorbent cylinder 52 gradually decreases, the squeezing surface 541 gradually squeezes the expanded absorbent component 53 as it rotates, thereby squeezing out excess water from inside the absorbent component 53. This excess water can then fall from the drain trough 512 into the filter tank 2, allowing the absorbent component 53 to continuously absorb water. In this embodiment, the squeezing surface 541 is a smoothly transitioned arc surface. Alternatively, the squeezing surface 541 can also be a smoothly transitioned inclined surface, as long as the condition that the distance between the squeezing surface 541 and the outer wall of the absorbent cylinder 52 gradually decreases along the rotation direction of the absorbent cylinder 52 is met.

[0042] Furthermore, in order to reduce the rigidity of the squeezing block 54 during actual use, the squeezing block 54 is slidably connected to the outer shell 51 along the radial direction of the suction cylinder 52, and the inner wall of the outer shell 51 is provided with a sliding groove 513 for the squeezing block 54 to slide. An elastic element 55 is provided in the sliding groove 513. In this embodiment, the elastic element 55 can be a compression spring, and the two ends of the elastic element 55 abut against the squeezing block 54 and the outer shell 51 respectively.

[0043] When the water-absorbing component 53 absorbs water and expands, it will come into contact with the water-squeezing block 54, and the water-squeezing surface 541 will squeeze the water-absorbing component 53. During this process, the water-squeezing block 54 will be subjected to the squeezing force applied by the water-absorbing component 53, thereby pushing the water-squeezing block 54 into the slide groove 513. After being pushed, the water-squeezing block 54 will compress the elastic component 55. The elastic component 55 will generate a restoring force under pressure, pushing the squeezing block out of the slide groove 513. In this way, the squeezing block can change its position by moving when squeezed by the water-absorbing component 53, so that the squeezing block can dynamically adjust its position according to different pressures, and better squeeze out the water in the water-absorbing component 53.

[0044] The implementation principle of a plastic product cooling tank in this application embodiment is as follows: After extrusion, the strip 3 enters the water cooling tank 1 under the guidance of the guide roller group. The cooling water 13 in the water cooling tank 1 can cool and shape the extruded strip 3 in time, reducing the deformation of the strip 3. Subsequently, the strip 3 after cooling and shaping is raised under the guidance of the filter roller group 5 and transported to the top of the filter tank 2 for filtration. The water suction element 53 on the water suction cylinder 52 contacts the strip 3 and can absorb the water on the surface of the strip 3, further removing the water on the surface of the strip 3, which facilitates the subsequent operation of the strip 3.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
