[0002] A plastic film is a plastic product with a certain thickness, width and infinite length, which is made of a high molecular synthetic material as the main raw material and evenly mixed with other auxiliary raw materials in a certain proportion, and formed on plastic forming machinery and equipment with a flat, smooth and soft surface. The main components of the plastic film include resins such as polyethylene, polypropylene, polyvinyl chloride, polyester, polystyrene, polyvinylidene chloride, polyamide, polyvinylidene fluoride, polycarbonate and polyurethane.

[0003] Plastic films are widely used in many fields. In the prior art, during the plastic film processing, it is necessary to cool it down first before the next step of processing. Cooling requires the use of a cooling and forming roller. The current cooling and forming roller has a single structure and poor cooling effect, which cannot meet the rapid forming requirements of plastic films and has insufficient practicability. Therefore, it is necessary to design a cooling and forming roller for plastic film processing to solve the above problems. Summary of the Utility Model

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-5 , a plastic film processing and cooling forming roller, including a base 1, a plurality of moving wheels 2 are fixedly installed on the bottom wall of the base 1, two cooling rollers 4 are rotatably installed on the upper end surface of the base 1 through two fixed plates 3. The cooling roller 4 is a roller through which cooling water is passed, mainly used to reduce the deformation caused by the shrinkage of the hot material during cooling. Annular cooling plates 5 are fixedly installed on the inner walls of the two cooling rollers 4. A first motor 6 is fixedly installed on the outer wall of the rotating shaft of one of the cooling rollers 4. Cooling water pipes 7 are rotatably installed on the outer walls of the two cooling rollers 4. Gears 8 are fixedly installed on the outer walls of the two cooling water pipes 7. A hair dryer 10 is fixedly installed on the upper end surface of the base 1 through a support mechanism. The support mechanism includes a support plate 9 fixedly installed on the upper end surface of the base 1. The hair dryer 10 is fixedly installed on the upper end surface of the support plate 9. An air blowing pipe 11 is fixedly installed on the outer wall of the outlet pipe of the hair dryer 10. Air blowing openings communicating with the inside are opened on the outer wall of the air blowing pipe 11. A pressing roller 13 is rotatably installed on the upper end surface of the base 1 through an installation mechanism. The installation mechanism includes two mounting plates 12 fixedly installed on the upper end surface of the base 1. The pressing roller 13 is rotatably installed between the two mounting plates 12.

[0023] A screw 15 is rotatably installed on the outer wall of the base 1 through a support frame 14. A second motor 16 connected to the screw 15 is fixedly installed on the upper end surface of the support frame 14. A moving sleeve 18 is threadedly installed on the outer wall of the screw 15 through a limiting mechanism. The limiting mechanism includes a limiting rod 17 fixedly installed on the inner wall of the support frame 14. The limiting rod 17 slidably penetrates through the moving sleeve 18. The limiting rod 17 can play a limiting role on the moving sleeve 18, so that the moving sleeve 18 can only axially move along the outer wall of the screw 15. A connecting frame 20 is fixedly installed on the outer wall of the moving sleeve 18 through a connecting mechanism. The connecting mechanism includes a connecting rod 19 fixedly installed on the outer wall of the moving sleeve 18. The end of the connecting rod 19 is fixedly connected to the outer wall of the connecting frame 20. An upper pressing roller 21 is rotatably installed on the inner wall of the connecting frame 20. A third motor 22 connected to the outer wall of the rotating shaft of the upper pressing roller 21 is fixedly installed on the outer wall of the connecting frame 20.

[0024] When the utility model is in use, the base 1 can be conveniently moved through a plurality of moving wheels 2. Before the plastic film is cooled and formed, the uncooled plastic film is first placed between two cooling rollers 4. Subsequently, the first motor 6 drives one of the cooling rollers 4 to rotate. When one of the cooling rollers 4 rotates, it can drive the other cooling roller 4 to rotate through the engagement of two gears 8, thereby extruding and cooling the plastic film. Cooling water is poured into the two cooling rollers 4 through the cooling water pipe 7, and the poured cooling water can quickly cool the plastic film through the cooperation with the annular cooling plate 5, thereby increasing the cooling effect on the plastic film. Then, during the winding process of the cooled plastic film, the hair dryer 10 can blow cold air through its outlet pipe to the air duct 11, and the cold air can be blown out through the air outlet in the air duct 11, thereby blowing the plastic film. Through the transfer of temperature, the forming speed of the plastic film can be accelerated;

[0025] Meanwhile, many wrinkles will appear after the plastic film is cooled and formed. The second motor 16 drives the screw 15 to rotate. The screw 15 drives the moving sleeve 18 to move through the cooperation with the limiting rod 17. The moving sleeve 18 then drives the connecting frame 20 to move downward through the cooperation with the connecting rod 19. When the connecting frame 20 moves, it can drive the upper pressing roller 21 inside it to move downward. Subsequently, the third motor 22 drives the upper pressing roller 21 to rotate and makes the upper pressing roller 21 approach the lower pressing roller 13 to roll the plastic film, thereby flattening the wrinkles of the plastic film and avoiding affecting the production effect of the plastic film, thus preventing the trouble of subsequent winding work.

[0026] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
