[0017] The following will be combined with the attached Figure 1-10 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-10 The present invention discloses a multifunctional production device for high-gloss matte excimer treatment of PET film, comprising a frame 1, a surface of which is mounted with a plurality of groups of horizontal rollers 6 arranged at equal distances, a mounting box 2 is fixed above the frame 1, and a plurality of groups of excimer lamps 5 are mounted inside the mounting box 2; A cooling assembly 3 is provided on one side of the surface of the frame 1.

A first material guide roller 34 is rotatably connected between two groups of first fixed frames 31. A cooling cylinder 32 is provided above the first material guide roller 34. A first connecting seat 37 and a second connecting seat 315 are provided on both sides of the cooling cylinder 32. A cooling pipe 312 with a U-shaped structure is fixedly connected inside one of the second connecting seats 315, and both ends of the cooling pipe 312 are respectively connected to a water outlet pipe 38 and a water inlet pipe 39 fixed on one side of the first connecting seat 37. A water tank 311 is fixedly connected to a side of the first fixed frame 31 close to the water inlet pipe 39. A water pump 310 is installed above the water tank 311, and the output end and the input end of the water pump 310 are respectively connected to the water inlet pipe 39 and the water tank 311, and the water outlet pipe 38 is connected to the inside of the water tank 311 through a connecting pipe. When processing the PET film, the PET film is transported by multiple groups of horizontal rollers 6. When passing through the installation box 2, multiple groups of excimer lamps 5 emit high-energy ultraviolet light to perform high-gloss or matte treatment on the PET film. After the excimer treatment, the surface temperature of the PET film will increase, and then when passing through the first guide roller 34, the heat at the film is transferred to the cooling cylinder 32, and the cooling medium inside the cooling tube 312 absorbs the heat on the surface of the cooling cylinder 32. Subsequently, the cooling water inside the water tank 311 is pumped out by the water pump 310 and transported to the inside of the cooling tube 312. The heat is taken away by the flow of the cooling medium inside the cooling tube 312, thereby reducing the temperature of the film. Rapid cooling helps to fix the treated microstructure of the PET film surface, making its gloss or matte effect more stable.

By setting the roller 316, when the cooling cylinder 32 rotates, it can drive the roller 316 to roll on the surfaces of the first connecting seat 37 and the second connecting seat 315, thereby improving the rotation stability of the cooling cylinder 32, and the roller 316 is arranged at an angle, so that when the cooling cylinder 32 is disassembled, the cooling cylinder 32 can be separated from the first connecting seat 37 and the second connecting seat 315.

One end of the second guide roller 46 passes through the side of the second fixed frame 41 and is connected to the second gear 410 arranged on one side of the second fixed frame 41. A transmission gear 49 is rotatably connected to the side of the second fixed frame 41 close to the first gear 48, and the transmission gear 49 is meshed and connected with the first gear 48 and the second gear 410 respectively. Before the excimer treatment, the PET film is pressed between the second guide roller 46 and the pressure wheel 47 by the pressure wheel 47, so that the movement of the PET film will drive the second guide roller 46 to move synchronously, and then the first gear 48 is driven to rotate by the second gear 410 and the transmission gear 49. The cleaning roller 45 is fixed with a brush, and the dust, debris and other large particles of impurities on the surface of the PET film are cleaned by the rotation of the cleaning roller 45, and the rotation direction of the cleaning roller 45 is opposite to the film movement direction, so as to improve the cleaning effect of the film. At the same time, the dust hood 44 is sucked by the dust suction fan 43 to remove the dust cleaned by the cleaning roller 45 to prevent it from adhering to the film surface again, so that the surface of the PET film remains clean to ensure the consistency of the treatment effect, and then the dust impurities absorbed by the dust suction fan 43 are collected by the dust collecting box 42. By moving the PET film as the power for the rotation of the cleaning roller 45, resistance can be generated to the movement of the cleaning roller 45, so as to ensure that the PET film remains in a tensioned state, avoid the PET film from being loosened during the transmission process, and ensure the accuracy of subsequent processing.

[0023] The present invention provides a multifunctional production device for high gloss matte excimer treatment of PET film through improvement, and its working principle is as follows; Before the excimer treatment, the PET film is pressed between the second guide roller 46 and the pressure wheel 47 by the pressure wheel 47. The movement of the PET film drives the second guide roller 46 to move synchronously, and then drives the first gear 48 to rotate through the second gear 410 and the transmission gear 49. The dust cleaning roller 45 rotates to clean the large particles of impurities such as dust and debris on the surface of the PET film. Then, the dust cleaning roller 45 is sucked away by the dust suction fan 43 to prevent the dust from being attached to the film surface again, so that the surface of the PET film is kept clean to ensure the consistency of the treatment effect. As the multiple groups of horizontal rollers 6 transport the PET film, in the process of passing through the installation box 2, the multiple groups of excimer lamps 5 are used to highlight or Matte treatment, after excimer treatment, the cooling cylinder 32 will absorb the heat on the surface of the film to reduce the temperature of the film. Rapid cooling helps to fix the treated microstructure of the PET film surface, making its gloss or matte effect more stable. During this period, the flow of cooling medium inside the cooling tube 312 will absorb and transport the heat on the surface of the cooling cylinder 32 to improve the cooling effect. The roller 316 is provided to facilitate the rotation of the cooling cylinder 32.
