[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] Reference Figure 1 and Figure 2 A plastic film processing and cleaning mechanism includes: a cleaning tank 1, a disinfection tank 2, a cleaning tank 3, an unwinding roller 4, a winding assembly 5, a guide roller assembly 6, a drying mechanism 7, and an air outlet mechanism 8. The disinfection tank 2 and the cleaning tank 3 are arranged adjacent to each other at the bottom of the cleaning tank 1. The unwinding roller 4 is horizontally arranged inside the cleaning tank 1, and the winding assembly 5 is horizontally arranged on one side of it. The drying mechanism 7 is arranged on one side of the cleaning tank 1 to blow hot air toward the rolled film. The air outlet mechanism 8 is arranged on one side of the cleaning tank 1 to guide the flow direction of the hot air blown by the drying mechanism 7. The guide roller assembly 6 is distributed inside the cleaning tank 1 to guide the rolled film into the disinfection tank 2 and the cleaning tank 3 and then into the winding assembly 5.

[0031] This application achieves the drying of plastic film by placing it on the unwinding roller 4, then on the guide roller assembly 6, and finally winding it into the take-up assembly 5. Disinfectant and cleaning liquids are then added to the disinfection tank 2 and the cleaning tank 3, and the take-up assembly 5 is activated to wind the film. The guide roller assembly 6 ensures that the plastic film is disinfected in the disinfection tank 2 before entering the cleaning tank 3 for cleaning. Simultaneously, the drying mechanism 7 blows hot air towards the plastic film to dry it. The air outlet mechanism 8 guides the flow of hot air to increase the contact area and time between the plastic film and the hot air, further improving the drying effect. This also reduces the internal temperature of the cleaning chamber 1, dissipating heat promptly and preventing excessive temperature from affecting the quality of the plastic film. Therefore, the plastic film is dried in a closed environment, improving the drying effect and reducing the footprint of the entire cleaning device.

[0032] Reference Figure 2 The drying mechanism 7 includes a drying box 701, a first electric fan 702, and a heating component. The drying box 701 is located on one side of the cleaning box 1 and is equipped with a heating component inside. The first electric fan 702 is located inside the drying box 701 and its air outlet faces the inside of the cleaning box 1.

[0033] Specifically, the heating component of this application can be achieved by setting a heating resistance wire inside the drying oven 701, and heating the heating resistance wire by energizing it. Then, the first electric fan 702 blows the outside air into the cleaning box 1 after it is heated by the heating resistance wire, thereby realizing the function of blowing hot air onto the plastic film.

[0034] Reference Figure 3 The air inlet and air outlet of the drying oven 701 are respectively equipped with filter screens 70101.

[0035] This application uses a filter 70101 to prevent external dust from being blown into the drying oven 701 by the first electric fan 702, which would cause the freshly washed plastic film to become dusty again.

[0036] Reference Figure 2 The air outlet mechanism 8 includes an air outlet box 801 and a second electric fan. The air outlet box 801 is located on one side of the cleaning box 1, and a second electric fan with an air outlet facing the outside of the cleaning box 1 is provided inside it.

[0037] By setting the air outlet mechanism 8, this application can maximize the contact area and time between hot air and plastic film to ensure that the plastic film can be dried, while preventing the internal temperature of the cleaning box 1 from being too high and affecting the quality of the plastic film.

[0038] Reference Figure 3 The winding assembly 5 includes a rotary motor 501 and a winding roller 502, wherein the winding roller 502 is horizontally rotatably mounted on one side of the unwinding roller 4 via the rotary motor 501.

[0039] This application achieves winding by placing a plastic film on a take-up roller 502 and then starting a rotary motor 501 to drive the take-up roller 502 to rotate.

[0040] Reference Figure 2 The guide roller assembly 6 includes a first guide roller 601, a second guide roller 602, and a tensioning assembly 605. The first guide roller 601 and the second guide roller 602 are respectively arranged horizontally in the disinfection tank 2 and the cleaning tank 3. The tensioning assembly 605 is located above the first guide roller 601 and the second guide roller 602.

[0041] The plastic film of this application is wound around the first guide roller 601, the tensioning component 605 and the second guide roller 602, so that it can enter the disinfection tank 2 and the cleaning tank 3 for disinfection and cleaning. At the same time, the tensioning component 605 can ensure that the plastic film remains taut.

[0042] Reference Figure 2 The cleaning box 1 is also horizontally equipped with a third guide roller 603 and a fourth guide roller 604 on the side near the drying mechanism 7 and the air outlet mechanism 8, to ensure that the film roll passes through the drying mechanism 7 and the air outlet mechanism 8.

[0043] This application, through its design, can further define the direction of hot air flow to ensure that the hot air comes into contact with the freshly cleaned plastic film, thereby drying the liquid on its surface.

[0044] Reference Figure 4The tensioning assembly 605 includes a lifting frame 60501, an elastic element 60503, and a fifth guide roller 60504. The lifting frame 60501 has several guide rods 60502 vertically arranged at its bottom and is vertically arranged above the first guide roller 601 and the second guide roller 602. Each guide rod 60502 is fitted with an elastic element 60503. The fifth guide roller 60504 is horizontally arranged on the lifting frame 60501.

[0045] When the plastic film is loose, the elastic element 60503 will drive the lifting frame 60501 to rise, thereby tightening the plastic film through the fifth guide roller 60504. When the plastic film is too tight, the elastic element 60503 will be compressed to drive the lifting frame 60501 to fall, thereby preventing the plastic film from breaking.

[0046] Reference Figure 2 and Figure 3 The disinfection tank 2 and the cleaning tank 3 are respectively provided with water inlets on one side and water outlets at the bottom of each.

[0047] This application connects the inlet to the corresponding disinfectant or cleaning liquid via pipes to supply liquid to the disinfection tank 2 and the cleaning tank 3; and connects the outlet to the drain via pipes to discharge liquid from the disinfection tank 2 and the cleaning tank 3.

[0048] Reference Figure 1 The side walls of the cleaning tank 3 and the disinfection tank 2 are respectively provided with liquid capacity viewing windows.

[0049] This application allows observation of the liquid volume and cleanliness of the disinfection tank 2 and the cleaning tank 3 through a liquid volume viewing window, thereby determining whether it is necessary to drain or add liquid.

[0050] In use, the device provided by this utility model involves placing the plastic film to be cleaned onto the unwinding roller 4, then onto the guide roller assembly 6, and finally winding it into the take-up assembly 5. Disinfectant and cleaning liquids are then added to the disinfection tank 2 and the cleaning tank 3. The take-up assembly 5 is then activated to wind the film. The guide roller assembly 6 ensures that the plastic film is disinfected in the disinfection tank 2 before entering the cleaning tank 3 for cleaning. Simultaneously, the drying mechanism 7 blows hot air towards the plastic film to dry it. The air outlet mechanism 8 guides the flow of hot air to increase the contact area and time between the plastic film and the hot air, further improving the drying effect. This also reduces the internal temperature of the cleaning chamber 1, dissipating heat promptly and preventing excessive temperature from affecting the quality of the plastic film. Thus, the plastic film is dried in a sealed environment, improving the drying effect and reducing the footprint of the entire cleaning device.

[0051] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0053] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
