Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a CPP film pretreatment device: it includes a main body 1 and a mounting frame 15. A water tank 12 is mounted on the mounting frame 15, and a pump body 11 is mounted on the water tank 12. A conveying pipe 21 is connected to the water tank 12. The end of the conveying pipe 21 away from the water tank 12 is connected to a water spray block 22. The pump body 11 drives the water inside the water tank 12 to spray water and rinse the film through the cooperation of the conveying pipe 21 and the water spray block 22. The outer wall of the water spray block 22 is connected to the inner wall of the mounting frame 15. A first motor 16 is mounted on the mounting frame 15.

The cleaning roller 23 is rotatably connected to the inner wall of the mounting frame 15. The first motor 16 drives the cleaning roller 23 to rotate, thereby cleaning the film.

[0019] Furthermore, a water leakage plate 17 is connected to the inner wall of the main body 1 of the device. The water leakage plate 17 can guide the cleaned water flow to the inside of the guide frame 18. The bottom surface of the main body 1 of the device is connected to the guide frame 18, and a filter box 20 is connected to the guide frame 18. A filter plate 19 is connected to the inner wall of the filter box 20. The filter box 20 and the filter plate 19 work together to filter the water flow. The filter box 20 and the outer wall of the water tank 12 are connected to a circulation pipe 10.

[0020] Furthermore, a support frame 4 is connected to the main body 1 of the device. Two fixing rings 29 are rotatably connected to the inner wall of the support frame 4. A second motor 3 is installed on the support frame 4. The output end of the second motor 3 is fixedly connected to one end of one of the fixing rings 29. The film can be fixed for pretreatment by using the fixing rings 29.

[0021] Furthermore, each fixing ring 29 is rotatably connected to a locking ring 30 via a pin, and each locking ring 30 is rotatably connected to a locking block 26 via a connecting rod. Each locking block 26 is adapted to the locking groove on the fixing ring 29. The film can be quickly fixed and removed through the cooperation of the locking ring 30 and the locking block 26.

[0022] Furthermore, a mounting frame 24 is connected to the main body 1 of the device, and an electric push rod 25 is mounted on the mounting frame 24. The output end of the electric push rod 25 is connected to a support frame 27, and a tension roller 28 is rotatably connected to the inner wall of the support frame 27. Through the cooperation of the electric push rod 25 and the tension roller 28, tension can be applied to the film to ensure that the film is in a taut state.

[0023] Furthermore, a second mounting frame 13 is connected to the main body 1 of the device. Two corona treatment rollers 14 are rotatably connected to the inner wall of the second mounting frame 13. A high voltage generator 8 is installed on the second mounting frame 13. Through the cooperation of the high voltage generator 8 and the corona treatment rollers 14, an electric spark is generated in the air and discharged through corona. This high-energy corona will bombard the surface of the CPP film, forming countless tiny pits that are invisible to the naked eye, increasing the surface area and roughness, thus facilitating subsequent painting and printing.

[0024] Furthermore, a collection frame 5 is connected to the main body 1 of the device, and a collection roller 7 is rotatably connected to the inner wall of the collection frame 5. A No. 3 motor 6 is installed on the collection frame 5.

[0026] The working principle of this utility model is as follows: First, the operator places the pre-treated film roll into the fixing ring 29. Then, the film roll is fixed by rotating the locking ring 30 and using the cooperation of the clip 26. Then, the tension of the film is increased by the cooperation of the electric push rod 25 and the tension roller 28 connected to the inner wall of the support frame 27. First, the cleaning roller 23 is driven by the first motor 16 to rotate and brush the film surface. Then, the water in the water tank 12 is driven by the pump body 11 and the water spray block 22 to rinse the film. Finally, the film is dried by the dryer set inside the mounting frame 15. The film is dried, and then, through the cooperation of high-voltage generator 8 and corona treatment roller 14, an electric spark is generated in the air. Through corona discharge, this high-energy corona bombards the surface of the CPP film, forming countless tiny pits that are invisible to the naked eye, increasing the surface area and roughness. Finally, the processed film is collected by the cooperation of motor 6 and collection roller 7. The rinsed water flows through the drain plate 17 into the guide frame 18, and then is filtered by the cooperation of the connected filter box 20 and filter plate 19. Finally, the filtered water is transported to the water tank 12 through the circulation pipe 10.
