PVC is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers and other aspects.

[0003] The cooling equipment for strip-shaped plastics extruded by a modified plastic extruder with the Chinese patent number CN220113974U involves the technical field of plastic cooling, especially the cooling equipment for strip-shaped plastics extruded by a modified plastic extruder. It includes a support frame, a water collection tank, a motor, a cooling device, a water pump and a pipeline. Regarding the problem of cooling the strip-shaped plastics, the use function is more reasonable, the overall support of the support frame is firm, the operation is simple in actual use, and the water cooling effect inside the water collection tank is good, improving the work efficiency.

[0004] When the hollow pipe strip body penetrates through the cooling water tank, the cooling water liquid only has a large-area cooling effect on the outer wall of the hollow pipe strip body, and it is not easy to uniformly cool and lower the temperature at the inner wall position of the hollow pipe strip body. Therefore, it is necessary to design a rapid cooling device for PVC plastic extrusion strips with inner wall cooling treatment to solve the above problems.

[0005] Therefore, a rapid cooling device for PVC plastic extrusion strips is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a rapid cooling device for PVC plastic extrusion strips to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A rapid cooling device for PVC plastic extrusion strips includes a cooling water tank, a refrigeration tank is fixedly connected to the front end of the cooling water tank, a cold air pipe is fixedly connected to the right end of the refrigeration tank, a number of cold transfer balls are filled in the inner end of the refrigeration tank, a material distribution storage tank is fixedly connected to the front end of the refrigeration tank, a horizontal screen is arranged in the middle of the inner end of the material distribution storage tank, a number of pores are formed on the surface of the horizontal screen, and the pores cooperate with the cold transfer balls. A plurality of guide roller shafts are connected between the left and right inner walls of the cooling water tank, and the hollow pipe strip body penetrates through the inner ends of both the cooling water tank and the refrigeration tank.

[0008] Further preferably, the hollow pipe strip body is located directly above a plurality of guide roller shafts, and through holes for passing materials are formed at both the front and rear ends of the cooling water tank and the refrigeration tank.

[0009] Further preferably, a plurality of material-passing inner holes are in a mutually connected state, and a plurality of cold-transferring small balls penetrate to the inner side of the hollow tube strip body.

[0010] Further preferably, a displacement suction pipe is fixedly connected to one end of the material distribution storage tank close to the refrigeration tank, and a pump is externally connected to the displacement suction pipe.

[0011] Further preferably, vertical grooves are symmetrically formed at the front and rear ends of the material distribution storage tank, and vibrators are installed at the inner ends of the vertical grooves.

[0012] Further preferably, vibration cross plates are symmetrically fixedly connected to the front and rear ends of the transverse screen, and the output ends of the vibrators are connected to the corresponding vibration cross plates.

[0013] Further preferably, a refrigerator is externally connected to the cold air duct, and a cold accumulation coating is fixedly connected to the surface of the cold-transferring small balls.

[0014] Further preferably, a number of cooling water liquids are filled in the inner end of the cooling water tank, and a cutting knife is externally connected to the material distribution storage tank.

[0015] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0016] 1. In this solution, a refrigeration tank is arranged between the cooling water tank and the material distribution storage tank. The refrigerator outside the cold air duct fills cold air into the refrigeration tank. A number of cold-transferring small balls in the refrigeration tank can be filled into the hollow tube strip body during the process of penetrating the hollow tube strip body. The cold air emitted by the cold-transferring small balls is in contact with the inner wall of the hollow tube strip body, and the inner wall position of the hollow tube strip body is also evenly cooled. The cooling effect on the hollow tube strip body is better. After the hollow tube strip body is output from the refrigeration tank, the hollow tube strip body is cut into small sections by cutting equipment and then falls on the material distribution storage tank for collection and temporary storage.

[0017] 2. After the displacement suction pipe is cut, the cold-transferring small balls inside it will then break away from the outside of the hollow tube strip body. The cold-transferring small balls can fall onto the lower inner wall of the material distribution storage tank through the transverse screen, and are drawn back into the refrigeration tank through the displacement suction pipe for repeated use. At the same time, vibrators can be arranged in the material distribution storage tank. The vibrators provide vibration force for the transverse screen, so that the cold-transferring small balls located in the hollow tube strip body in the material distribution storage tank can smoothly break away and fall to the lower side position of the transverse screen, making the separation effect better.

Detailed implementation manners

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figures 1-5As shown in the figure, an embodiment of the utility model provides a rapid cooling device for PVC plastic extrusion strips, which includes a cooling water tank 1. A refrigeration tank 5 is fixedly connected to the front end of the cooling water tank 1. A cold air duct 4 is fixedly connected to the right end of the refrigeration tank 5. A number of cold transfer balls 9 are filled in the inner end of the refrigeration tank 5. A material distribution storage tank 7 is fixedly connected to the front end of the refrigeration tank 5. A transverse screen 8 is arranged in the middle of the inner end of the material distribution storage tank 7. A number of pores are formed on the surface of the transverse screen 8, and the pores cooperate with the cold transfer balls 9. A plurality of guide roller shafts 2 are connected between the left and right inner walls of the cooling water tank 1. A hollow tube strip body 3 penetrates through the inner ends of both the cooling water tank 1 and the refrigeration tank 5.

[0030] The hollow tube strip body 3 is located directly above a plurality of guide roller shafts 2. Through holes 12 are formed at both the front and rear ends of both the cooling water tank 1 and the refrigeration tank 5. The plurality of through holes 12 are interconnected. A number of cold transfer balls 9 penetrate to the inner side of the hollow tube strip body 3. A displacement suction pipe 6 is fixedly connected to one end of the material distribution storage tank 7 close to the refrigeration tank 5. The displacement suction pipe 6 is externally connected to a pump.

[0031] Embodiment 2

[0032] In one embodiment, vertical grooves are symmetrically formed at both the front and rear ends of the material distribution storage tank 7. Vibrators 11 are installed at the inner ends of the vertical grooves. Vibration transverse plates 10 are symmetrically and fixedly connected to both the front and rear ends of the transverse screen 8. The output ends of the vibrators 11 are connected to the corresponding vibration transverse plates 10.

[0033] A refrigerator is externally connected to the cold air duct 4. A cold accumulation coating is fixedly connected to the surface of the cold transfer balls 9. A number of cooling water liquids 13 are filled in the inner end of the cooling water tank 1. A cutting knife is externally connected to the material distribution storage tank 7.

[0034] When the utility model works: in this solution, the hollow pipe strip body 3 penetrates through the inside of the cooling water tank 1. The cooling water liquid 13 contacts the hollow pipe strip body 3 to play a shaping and cooling role on the outer wall surface of the hollow pipe strip body 3, and then it is transported above the material distribution storage tank 7 for slitting operation by a cutting knife. When the hollow pipe strip body 3 penetrates through the cooling water tank 1, the cooling water liquid 13 only has a large-area cooling effect on the outer wall of the hollow pipe strip body 3, and it is not easy to uniformly cool down the inner wall position of the hollow pipe strip body 3. Therefore, a refrigeration tank 5 is arranged between the cooling water tank 1 and the material distribution storage tank 7. The refrigeration tank 5 is filled with cold air by a refrigerator outside the cold air pipe 4. A number of cold air transfer balls 9 in the refrigeration tank 5 can be filled into the hollow pipe strip body 3 during the process of the hollow pipe strip body 3 penetrating through. The cold air emitted by the cold air transfer balls 9 contacts the inner wall of the hollow pipe strip body 3, and the inner wall position of the hollow pipe strip body 3 is also uniformly cooled down, so that the cooling effect on the hollow pipe strip body 3 is better. After the hollow pipe strip body 3 is output from the refrigeration tank 5, the hollow pipe strip body 3 is cut into small sections by a cutting device and then falls on the material distribution storage tank 7 for collection and temporary storage. After the displacement suction pipe 6 is cut, the cold air transfer balls 9 inside it will fall out of the hollow pipe strip body 3. The cold air transfer balls 9 can fall onto the inner wall of the lower part of the material distribution storage tank 7 through the transverse screen 8 and be sucked back into the refrigeration tank 5 through the displacement suction pipe 6 for repeated use. At the same time, a vibrator 11 can be arranged in the material distribution storage tank 7. The vibrator 11 provides a vibration force for the transverse screen 8, so that the cold air transfer balls 9 located in the hollow pipe strip body 3 in the material distribution storage tank 7 can be smoothly separated and fall to the lower side position of the transverse screen 8, making the separation effect better.

[0035] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered by the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
