Technical Field

[0001] This utility model relates to the field of polyester film technology, specifically to a corona treatment device for composite polyester films. Background Technology

[0002] Composite polyester films are film materials that combine polyester (usually PET) with other materials or coatings to enhance their specific properties. This composite technology aims to give the film more functionality and higher performance, making it suitable for a wider range of industrial applications.

[0003] Corona treatment of composite polyester films is a surface treatment technology mainly used to improve the surface properties of materials, especially to increase their surface energy, thereby improving the wettability and adhesion of the materials. Existing corona treatment equipment is relatively fixed in position with the material being treated, which limits its application to materials of different sizes and specifications. Moreover, loosening during treatment will affect the corona treatment effect. Therefore, we propose a corona treatment device for composite polyester films. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a corona discharge device for composite polyester film, including a working plate 1, a support frame 2 fixedly installed at the bottom of the working plate 1, two sets of mounting frames 3 fixedly installed at the top of the working plate 1, a corona discharge mechanism 5 for adjusting the corona discharge angle between the two sets of mounting frames 3, a corona discharge mechanism 5 for adjusting the position between the polyester film and the corona discharge limiting mechanism 4 between the two sets of mounting frames 3, and a tensioning mechanism 6 for tensioning the polyester film is provided at the top of the working plate 1 and on both sides of the mounting frames 3.

[0019] The two sets of tensioning mechanisms 6 ensure that the film to be processed is always in a taut state, thereby guaranteeing the accuracy of corona treatment. The corona limiting mechanism 4 ensures that the film can always pass through the corona treatment mechanism 4 for corona treatment. The corona limiting mechanism 4 can move up and down, thereby changing the distance with the corona treatment mechanism 5 when processing films of different thicknesses, making the corona treatment process more adaptable. In addition, the corona treatment mechanism 5 can be angled to ensure the normal corona treatment when directly collecting the material after corona treatment.

[0020] Please see Figure 1 The tensioning mechanism 6 includes a limiting sleeve 7, a sliding rod 8, a first fixed rod 9, a tensioning roller 10, and a spring 12. The limiting sleeve 7 is fixedly installed on the working plate 1. The sliding rod 8 is slidably connected inside the limiting sleeve 7. The first fixed rod 9 is fixedly connected to the sliding rod 8. The tensioning roller 10 is rotatably connected to the outer surface of the first fixed rod 9. The tensioning roller 10 is made of stainless steel. A fixing plate 11 is fixedly installed at the bottom of the sliding rod 8. A spring 12 is fixedly installed at the top of the fixing plate 11 and on the outer surface of the sliding rod 8. The top of the spring 12 is fixedly installed at the bottom of the working plate 1.

[0021] In this process, the film that needs to be corona treated passes through the top of the tensioning roller 10 and the bottom of the corona limiting mechanism 4. Then, during the film winding motion, the spring 12 can continuously push the slide bar 8, the first fixed rod 9 and the tensioning roller 10 to move along the inside of the limiting sleeve 7, so that the loose film can always be in a taut state.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The corona limiting mechanism 4 includes a sliding groove 13, a slider 14, a second fixed rod 15, a limiting roller 16, and a threaded rod 18. The mounting frame 3 has a sliding groove 13, and the slider 14 is slidably connected inside the sliding groove 13. The second fixed rod 15 is fixedly installed on the slider 14, and the limiting roller 16 is rotatably installed on the outer surface of the second fixed rod 15. A threaded sleeve 17 is fixedly installed on the top of the mounting frame 3, and the threaded rod 18 is threadedly connected inside the threaded sleeve 17. The bottom of the threaded rod 18 is rotatably connected to the slider 14.

[0023] Specifically, the upper and lower positions of the limiting roller 16 are adjusted according to the required thickness of the film to be corona treated. When adjusting the position of the limiting roller 16, the threaded rod 18 is rotated so that the threaded rod 18 moves up and down along the inside of the threaded sleeve 17. This can pull the slider 14 up and down, and the up and down movement of the slider 14 can make the second fixed rod 15 and the limiting roller 16 move up and down, thereby changing the distance between them and the corona treatment mechanism 5, making the corona treatment mechanism 4 more adaptable during corona treatment.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The corona mechanism 5 includes a mounting base 19, a corona plate 20, and an adjustment plate 21. The mounting frame 3 is rotatably connected to the mounting base 19 via a rotating shaft. The corona plate 20 is fixedly mounted on two sets of mounting bases 19. One set of rotating shafts is fixedly connected to the adjustment plate 21. The mounting frame 3 has multiple sets of positioning slots 22. The adjustment plate 21 is inserted with a pin 23 that is inserted into the positioning slot 22. Multiple sets of positioning slots 22 are provided, and the multiple sets of positioning slots 22 are interconnected.

[0025] When the film is directly wound up after corona treatment, the mounting base 19 and the corona plate 20 can be rotated to make them rotate along the rotation axis. After the angle adjustment is completed, the pin 23 is inserted into the positioning groove 22 to lock and fix the adjustment plate 21 and the rotation axis, so that there will be no deviation during the corona treatment. The positioning groove 22 is set to multiple interconnected sets so that the angle of the corona plate 20 can be adjusted more accurately.

[0026] Please see Figure 1 and Figure 2 The corona plate 20 is configured in an arc shape, which can fully cooperate with the film guided and limited by the limiting roller 16 to ensure better corona treatment of the film.

[0027] In use, firstly, the two sets of tensioning mechanisms 6 ensure that the film to be processed is always in a taut state, thus guaranteeing the accuracy of corona treatment. Secondly, the corona limiting mechanism 4 ensures that the film can always pass through the corona treatment mechanism 4 for corona treatment. The corona limiting mechanism 4 can move up and down, thus changing the distance from the corona treatment mechanism 5 when processing films of different thicknesses, making the corona treatment process more adaptable. Furthermore, the corona treatment mechanism 5 can be angled to facilitate proper corona treatment during direct film collection after treatment. The film to be corona treated is passed through the top of the tensioning roller 10 and the bottom of the corona limiting mechanism 4. Then, during the film winding motion, the spring 12 continuously pushes the slide bar 8, the first fixed rod 9, and the tensioning roller 10 to move along the inside of the limiting sleeve 7, thus ensuring that the loose film is always in a taut state. According to the requirements... To adjust the vertical position of the film thickness adjustment limiting roller 16 for corona treatment, rotate the threaded rod 18 while adjusting the position of the limiting roller 16. This causes the threaded rod 18 to move up and down along the inside of the threaded sleeve 17, which in turn pulls the slider 14 up and down. The up-and-down movement of the slider 14 causes the second fixed rod 15 and the limiting roller 16 to move up and down, thereby changing the distance between them and the corona treatment mechanism 5. This makes the corona treatment mechanism 4 more adaptable. When the film is directly wound up after corona treatment, the mounting base 19 and the corona plate 20 can be rotated to make them rotate along the rotating shaft. After the angle adjustment is completed, insert the pin 23 into the positioning groove 22 to lock and fix the adjusting plate 21 and the rotating shaft. This prevents deviation during corona treatment. The positioning groove 22 is set to be multiple interconnected sets, which allows for more precise angle adjustment of the corona plate 20.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
