[0030] Example:

[0031] This embodiment provides a thin film coating machine, referring to Figure 1 , including a coating module 1, the coating module 1 belongs to the existing equipment, the coating module 1 can perform coating processing on the surface of the film, a cover shell 2 is installed at the inlet and outlet of the coating module 1, and the film can be wrapped before entering the coating module 1 for processing, and a partition 5 is embedded and installed in the middle of the cover shell 2. The partition 5 divides the internal space of the cover shell 2 into two parts, and the film passes through the upper space of the cover shell 2. At the same time, a roller 6 is arranged on the inner side of the cover shell 2 above the partition 5. The roller 6 can support the film, guide the film, and prevent the film from falling down The pendant contacts the partition 5, and the roller 6 can rotate to avoid wearing the film. When the film passes through, an air outlet pipe 3 is arranged between the rollers 6 on the inner side of the cover shell 2. The air outlet pipe 3 can clean the film, and the air outlet pipe 3 includes a pipe 31. The pipe 31 can provide a clean airflow. The pipe 31 is located at one end of the inner side of the cover shell 2 and a nozzle 33 is installed. The nozzle 33 discharges air in the direction of the film to clean the surface of the film. The nozzle 33 is arranged perpendicular to the roller 6, so that the film can be supported by the roller 6 while the film is stable during air outlet cleaning.

[0032] In a further embodiment, referring to Figure 3A cleaning gap 8 is formed between the cover shell 2 and the partition 5. The cleaning gap 8 facilitates the smooth passage of the film. Two nozzles 33 are provided. The nozzles 33 are symmetrically arranged on both sides of the film. This can ensure that the forces of the exhaust gas acting on the film offset each other and avoid deformation of the film. Both sides of the film can be cleaned at the same time to improve the cleaning efficiency. The two nozzles 33 are stacked up and down in the cleaning gap 8, and cleaning can be performed under the wrapping of the cover shell 2 to avoid the internal and external environment affecting the cleaning effect.

[0033] In a further embodiment, referring to Figure 2 An air outlet 7 is formed at the inclined plate 52 and the end of the cover shell 2 away from the coating module 1. The airflow ejected from the nozzle 33 carries away the debris on the surface of the film and can be ejected from the cover shell 2 from the air outlet 7 to ensure the cleanliness of the internal space of the cover shell 2. At the same time, a roller 6 is provided on the cover shell 2 at the air outlet 7 to support the film to prevent the air outlet 7 from wearing the film surface.

[0034] In a further embodiment, referring to Figure 4 Two inclined surfaces are respectively arranged at the opposite ends of the two nozzles 33, and the inclined surfaces are tilted toward the front and the rear respectively, so that air can be discharged to the front and the rear at the same time, so that the film can be cleaned efficiently. The two inclined surfaces intersect at the middle of the nozzle 33, and can form an intersecting airflow in the middle of the film, ensuring that the surface of the film can be covered by the airflow, thereby achieving the effect of thoroughly cleaning the surface of the film.

[0035] In a further embodiment, referring to Figure 3 The partition 5 includes a flat plate 51. The distance between the flat plate 51 and the cover shell 2 is large, which provides a larger installation space for the nozzle 33 to ensure normal cleaning. The flat plate 51 is lifted up at one end away from the coating module 1 to form an inclined plate 52. The inclined plate 52 can reduce the diameter of the air outlet 7. The reduced diameter at the position of the air outlet 7 can form an airflow with a higher flow rate, which can perform the first stage of cleaning of part of the dust on the surface of the film, reduce the amount of dust entering the inside of the cover shell 2, and improve the cleaning effect.

[0036] In a further embodiment, referring to Figure 3 The air outlet pipe 3 also includes a filter box 32, which can filter the airflow in the pipe 31 to obtain clean air. The air inlet end of the pipe 31 is arranged at the end of the filter box 32. The filter box 32 is provided with a fan 4 at one end away from the pipe 31. The fan 4 can continuously transport the external airflow into the filter box 32, so that the nozzle 33 can continuously spray clean airflow. The filter box 32 is located below the partition 5, making full use of the internal space of the cover shell 2. The inclined plate 52 is tilted upward, which is convenient for disassembly and maintenance of the filter box 32.

[0037] In a further embodiment, referring to Figure 4The rollers 6 are arranged in groups of two, and each group of rollers 6 is stacked up and down. The film can be clamped by the rollers 6 to ensure that the film can pass horizontally and avoid the film from shaking up and down. A material passing gap is formed between the two rollers 6 to ensure that the film can pass through the rollers 6 stably.

[0038] The fan and coating module involved in the embodiment are existing products customized and produced by the manufacturer, and their supporting control systems, solenoid valves, control switches and circuit pipelines can also be provided by the manufacturer. In addition, the power supply module, circuit and electronic components and control module involved in the utility model are all existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
