Detailed Implementation
[0019] 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.
[0020] See Figures 1-3 In this embodiment of the present invention, a corona discharge mechanism for a coating machine includes a housing 1, with a placement opening 2 on one side of the housing 1. A fixed platform 3 is fixedly connected inside the housing 1, and a first sliding groove 4 is provided inside the fixed platform 3. A first fixed rod 5 is fixedly connected inside the first sliding groove 4, and a slider 6 is slidably connected to the first fixed rod 5. An insulating plate is fixedly connected to the slider 6 through the first sliding groove 4. A movable groove 8 is provided inside the fixed platform 3, and a conductive rod 9 is provided inside the movable groove 8. One end of the conductive rod 9 passes through the insulating plate and is fixedly connected to a discharge plate 10, and the other end of the conductive rod 9 is fixedly connected to... The system includes a capacitor 11. A mounting bracket 16 is fixedly connected to the outer wall of the chassis 1. A mounting frame 17 is fixedly connected to the mounting bracket 16. A second fixing rod 18 is fixedly connected inside the mounting frame 17. A sliding frame 19 is slidably connected to the second fixing rod 18. A mounting plate 24 is fixedly connected to the sliding frame 19. Multiple sets of equidistantly distributed discharge cones 25 are fixedly connected to the mounting plate 24. Each of the mounting plate 24 and the capacitor 11 is connected to a set of terminals 23. A first driving assembly is provided inside the fixed platform 3. A second driving assembly is provided inside the mounting frame 17.
[0021] This invention first attaches the film to be processed onto a discharge plate 10 and connects it to a high-voltage circuit via two sets of terminals 23. Then, by setting up a capacitor, electrons in the discharge plate 10 flow into the capacitor, at which point the discharge plate 10 carries a high voltage positive charge. Then, the high-voltage circuit injects electrons into multiple sets of discharge cones 25, at which point the discharge cones 25 carry a high voltage negative charge. Then, when the voltage between the discharge plate 10 and the discharge cones 25 is large enough, a discharge occurs between the discharge plate 10 and the discharge cones 25. A large number of electrons flow from the discharge cones 25 through the air and into the discharge plate 10. During this process, electrons pass through the film, thereby corona-electrocuting the film. At the same time, this invention can drive the insulating plate to move through the first drive component, and drive the sliding frame 19 to move back and forth through the second drive component. At this time, the relative positions of the discharge points between the films move uniformly, thereby achieving uniform corona-electrocuting of the film.
[0022] In one instance of this embodiment, please refer to Figures 1-3 Multiple sets of equidistant arc-extinguishing grids 26 are provided below the discharge cone 25. The present invention accelerates the elimination of high-voltage arc between the discharge plate 10 and the discharge cone 25 by setting the arc-extinguishing grids 26.
[0023] In one instance of this embodiment, please refer to Figures 1-3 The first drive assembly includes a second slide groove 12 disposed in the fixed platform 3, a first screw 13 rotatably connected in the second slide groove 12, a drive block 14 threadedly connected to the first screw 13, the drive block 14 fixedly connected to the insulating plate, a first motor 15 fixedly connected to the outer wall of the chassis 1, and the output shaft of the first motor 15 fixedly connected to the drive end of the first screw 13.
[0024] The first drive assembly drives the first screw 13 to rotate via the first motor 15, and then converts the rotational motion of the first screw 13 into the linear motion of the drive block 14 via the threaded connection between the first screw 13 and the drive block 14, which in turn drives the insulating plate to move linearly.
[0025] In one instance of this embodiment, please refer to Figures 1-3 The second drive assembly includes a second screw 20 rotatably connected within the mounting bracket 17, a drive cylinder 21 threadedly connected to the second screw 20, the drive cylinder 21 being fixedly connected to the sliding bracket 19, a second motor 22 being fixedly connected to the mounting bracket 17, and the output shaft of the second motor 22 being fixedly connected to the drive end of the second screw 20.
[0026] The second drive assembly drives the second screw 20 to rotate via the second motor 22. The screw 20 is then connected to the drive cylinder 21 via a thread, converting the rotational motion of the screw 20 into the linear motion of the drive cylinder 21. The drive cylinder 21 drives the sliding frame 19 to move linearly. The reciprocating forward and reverse rotation of the second motor 22 is used to drive the drive cylinder 21, thereby achieving the reciprocating linear motion of the sliding frame 19.
