[0023] like Figure 2 , 3As shown in Figures 4 and 5, the adjustment limiting assembly 9 includes a first limiting rod 901, a first sliding plate 905, and a second sliding plate 909. The first limiting rod 901 is fixedly installed between the top ends of two guide rollers 10. The two first sliding plates 905 are slidably installed in the middle of the guide rollers 10, and the second sliding plate 909 is slidably installed in the middle of the voltage roller 8. Each pair of first sliding plates 905 is connected by a second limiting rod 902. A bidirectional lead screw 903 is installed on the first limiting rod 901, and two lead screw sleeves 904 are sleeved in the middle of the bidirectional lead screw 903. The two lead screw sleeves 904 are respectively connected to the two second limiting rods 902. The first slide plate 905 has a first groove 910 on its circumference. A first rotating shaft 911 is rotatably installed between the inner walls of the two sides of the first groove 910. A first connecting rod 906 is fixedly installed on the circumference of the first rotating shaft 911. The second slide plate 909 has a second groove 912 on both sides of its circumference. A second rotating shaft 913 is rotatably installed between the inner walls of the two sides of the second groove 912. A second connecting rod 908 is fixedly installed on the circumference of the second rotating shaft 913. The first connecting rod 906... The top ends of the second connecting rod 908 are connected by a mounting shaft 907. By rotating the bidirectional lead screw 903, the two lead screw sleeves 904 can be driven to move towards or away from each other in the middle of the bidirectional lead screw 903. The first sliding plate 905 has a first groove 910 on its circumference, and a first rotating shaft 911 is rotatably mounted between the inner walls of the two sides of the first groove 910. The first connecting rod 906 is fixedly mounted on the circumference of the first rotating shaft 911. The second sliding plate 909 has second grooves 912 on both sides of its circumference.

At this time, the two first sliding plates 905 and the two second sliding plates 909 can be driven to move away from each other or closer to each other, adjusting the two first sliding plates 905 and the two second sliding plates 909 to a suitable distance from the film, so as to limit the film and prevent the film from shifting in position during winding after corona treatment, thus affecting the winding efficiency.

[0024] The working principle of a corona device for thin film surface treatment:

[0025] In use, when this device is needed for corona treatment, the output end of the hydraulic cylinder 5 is first extended or retracted, driving the slider 11 to slide inside the slide groove 3. Simultaneously, the servo motor 4 is driven to move downwards, and the voltage roller 8 is also driven downwards to adjust the distance between the voltage roller 8 and the high-voltage electrode 7. This allows for corona treatment of films of different thicknesses. The distances between the two first sliding discs 905 and the two second sliding discs 909, respectively, between the voltage roller 8 and the guide roller 10 are adjusted according to the width of the film. By rotating the bidirectional lead screw 903, the two lead screw sleeves 904 can be driven to move towards or away from each other in the middle of the bidirectional lead screw 903. Because the first sliding disc 905 has a first groove 910 on its circumference, and a first rotating shaft 911 is rotatably mounted between the inner walls of both sides of the first groove 910, the first rotating shaft 911... A first connecting rod 906 is fixedly installed on the surface of the second slide 909. Second grooves 912 are formed on both sides of the circumference of the second slide 909. A second rotating shaft 913 is rotatably installed between the inner walls of the two sides of the second groove 912. A second connecting rod 908 is fixedly installed on the circumference of the second rotating shaft 913. The top ends of the first connecting rod 906 and the second connecting rod 908 are connected by a mounting shaft 907. This allows the two first slides 905 and the two second slides 909 to move away from or towards each other, adjusting them to a suitable distance from the film to limit the film's position and prevent it from shifting during winding after corona treatment, thus affecting winding efficiency. After adjustment, the film to be corona treated passes sequentially between the guide roller 10 and the voltage roller 8, and is corona treated by the voltage roller 8 and the high-voltage electrode 7.

Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
