[0025] Referring to Figure 1 -3, the present utility model provides a PE protective film coater, including:

[0026] The processing unit 100 includes a base 101. In the middle of the upper surface of the base 101, a processing box assembly 102 is fixedly connected. On one side inside the processing box assembly 102, a tensioning assembly 103 is provided. Inside the processing box assembly 102, a coating roller shaft 104 is rotatably connected. Inside the base 101, a liquid storage tank 108 is fixedly connected. On the upper surface of the liquid storage tank 108, a water pump 109 is fixedly connected. The output end of the water pump 109 is fixedly connected to one end of the coating roller shaft 104. On the other side inside the processing box assembly 102, a dryer 106 is fixedly connected. On the outer surface of one side of the processing box assembly 102, an extension plate 110 is fixedly connected. On the outer surface of the extension plate 110, a fan 111 is fixedly connected. On one side of the upper surface of the base 101, a winding assembly 112 is provided. The PE film first passes through the tensioning assembly 103 to ensure that the material is flat and free of wrinkles before entering the coating area. The coating roller shaft 104 extracts the coating from the liquid storage tank 108 through the water pump 109 and evenly coats it on the PE film passing through the coating area. The coated film enters the dryer 106 for rapid drying to ensure the curing of the coating. The fan 111 on the extension plate 110 helps with heat dissipation and accelerates the drying process. The processed PE film is wound by the winding assembly 112 for easy storage and subsequent use.

[0027] Among them, the processing box assembly 102 includes a box body 102a. The lower surface of the box body 102a is fixedly connected to the upper surface of the base 101. Inside the box body 102a, a partition 102b is fixedly connected. Openings 102c are formed on the outer surfaces of both sides of the box body 102a and the partition 102b. Inside the openings 102c, auxiliary wheels 102d are rotatably connected. On the upper surface of the box body 102a, an exhaust gas processor 107 is fixedly connected. The input end of the exhaust gas processor 107 is fixedly connected to the inside of the box body 102a. On the inner bottom wall of the box body 102a, a waste box 105 is fixedly connected. The waste box 105 is arranged below the coating roller shaft 104. The auxiliary wheels 102d are installed in the openings 102c of the processing box assembly 102 to guide and stabilize the movement of the PE film, ensuring that the film maintains the correct position and tension during the coating process. The exhaust gas processor 107 is used to collect and process harmful gases and volatile organic compounds generated during the coating process, absorbing the exhaust gas from the inside of the box body 102a through the input end, reducing the impact on the working environment and the health of operators. The waste box 105 collects the waste and spilled coating generated during the coating process, keeping the working area clean and facilitating the recycling and treatment of the waste.

[0028] Further, the tensioning assembly 103 includes an electric guide rail 103a. The outer surface of the electric guide rail 103a is fixedly connected to the inner wall of the box body 102a. A moving roller 103b is slidably connected to the outer surface of the electric guide rail 103a. A fixed roller 103c is arranged on one side of the electric guide rail 103a. Both ends of the fixed roller 103c are rotatably connected to the inner wall of the box body 102a. A plurality of tensioning assemblies 103 are provided and distributed on both sides of the coating roller 104. The electric guide rail 103a adjusts the position of the moving roller 103b to control the tension of the PE film. During the coating process, the electric guide rail 103a can move precisely, so that the moving roller 103b applies an appropriate tension to the PE film, thereby maintaining the flatness and tension consistency of the film material. The fixed roller 103c serves as a support point to ensure the stable transmission of the film material during the coating process. A plurality of tensioning assemblies are distributed on both sides of the coating roller 104 and work together to maintain the uniform distribution of the width and tension of the film, improving the coating quality.

[0029] Furthermore, the winding assembly 112 includes a fixed bracket 112a. The lower end of the fixed bracket 112a is fixedly connected to the upper surface of the base 101. An upper part of the outer surface of the fixed bracket 112a is fixedly connected with a driving motor 112b. The output end of the driving motor 112b is fixedly connected with a winding roller 112c. The winding roller 112c is arranged on one side of the opening 102c. The driving motor 112b is used to control the rotation of the winding roller 112c, thereby realizing the automatic winding of the PE film. The fixed bracket 112a provides a stable installation platform to ensure the stability of the driving motor 112b and the winding roller 112c during operation. The output end of the driving motor 112b is mechanically connected to the winding roller 112c to drive the winding roller 112c to rotate and wind up the processed PE film, which is convenient for subsequent processing and transportation.

[0030] During use, first place the protective film inside the box body 102a, start the electric guide rail 103a to drive the moving roller 103b to cooperate with the fixed roller 103c to tension the protective film. Then start the water pump 109 to pump the paint inside the liquid storage tank 108 into the inside of the coating roller 104 and apply it to the protective film through the discharge port. Further, during drying, the waste gas generated during drying can be treated by the waste gas processor 107. When the dried protective film exits the box body 102a, it is cooled by the fan 111, which is convenient for the winding roller 112c to wind up.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
