DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4As shown, a copper-plastic strip composite processing equipment comprises a first unwinding device 1, a second unwinding device 2, a winding device 3, a gluing device 4 and a rolling device, a copper strip roll 5 is placed on the first unwinding device 1, a film roll 6 is placed on the second unwinding device 2, the winding device 3 is used to wind up a copper-plastic strip composited with a copper strip and a film and wind it into a copper-plastic strip roll 7, the gluing device 4 is used to apply an adhesive to the upper surface of the copper-plastic strip, the rolling device comprises an operating table 8, and guard plates 9 are symmetrically arranged on the upper surface of the operating table 8, the second unwinding device 2 is arranged on two guard plates 9, and support plates 10 are also arranged on the two guard plates 9 of the operating table 8, a steering roller 11 is arranged between the two support plates 10, and a guard plate 9 is arranged on the upper surface of the operating table 8 and between the two guard plates 9. A holding frame 12 is provided with a roller pressing cylinder 13, and a first motor 14 for controlling the rotation of the roller pressing cylinder 13 is provided on the outer surface of the operating table 8. An oblique scraping assembly is symmetrically provided on the upper surface of the holding frame 12, and the oblique scraping assembly includes an extension plate 15, one end of the extension plate 15 is fixedly connected to the holding frame 12 by a bolt 16, a through groove is provided on the extension plate 15, and a scraper 17 is slidably connected inside the through groove, and a frame 18 is provided on the upper surface of the extension plate 15. A top block 19 is symmetrically provided on the upper end of the scraper 17, and a vertical rod 20 is provided on the upper surface of the top block 19. The vertical rod 20 passes through the frame 18, and the upper ends of the two vertical rods 20 are connected by a cross bar and a cross plate 21. A spring 22 is sleeved on the vertical rod 20, and the spring 22 is located between the frame 18 and the top block 19.

[0019] The first unwinding device 1, the second unwinding device 2 and the winding device 3 can respectively control the unwinding and winding of the copper strip roll 5, the film roll 6 and the copper plastic strip roll 7. The gluing device 4 applies glue to the upper surface of the copper strip through a gluing roller arranged in the gluing box, and can also spray the glue on the upper surface of the copper strip through a nozzle. The second winding device 3 controls its rotation through a second motor 24. Since the first unwinding device 1, the second unwinding device 2, the winding device 3 and the gluing device 4 are all existing technologies, the specific structure and function are not repeated here.

[0020] When the copper strip is on the operating table 8, the upper surface of the copper strip is coated with a glue layer, and the film released by the second unwinding device 2 is in contact with the upper surface of the copper strip, and then the film and the copper strip are pressed together by the rolling cylinder 13. At the same time, the rolling cylinder 13 is located in the middle of the operating table 8, and the distances between the two ends of the rolling cylinder 13 and the two side guard plates 9 are equal. When the rolling cylinder 13 presses the film and the copper strip together, the pressure between the film and the copper strip on both sides of the rolling cylinder 13 is small, and the film below the rolling cylinder 13 and the copper strip are The air will move to both sides of the roller cylinder 13. The length of the roller cylinder 13 is smaller than the width of the copper belt, which reduces the moving distance of the air between the film and the copper belt, so as to avoid the existence of air between the film and the copper belt passing through the roller cylinder 13 as much as possible. When the air moves to the film on both sides of the roller cylinder 13 and between the copper belt, the air moved to both sides of the roller cylinder 13 and between the film and the copper belt is squeezed out to the outside of the copper belt and the film through the inclined scraper 17, thereby reducing the probability of bubbles between the film and the copper belt.

[0021] The angle between the scraper 17 and the roller cylinder 13 can be adjusted. When the angle of the scraper 17 needs to be changed, it is only necessary to loosen the bolts 16 that fix the extension plate 15 and the retaining frame 12, and then adjust the angle of the scraper 17 to a suitable angle, and then tighten the bolts 16 to complete the position adjustment of the scraper 17. The lower end face of the scraper 17 is provided with an arc surface for reducing the friction between the scraper 17 and the film. The scraper 17 is made of nylon material.

[0022] The spring 22 on the vertical rod 20 is always in a compressed state. The elastic force of the spring 22 can cause the top block 19 to move downward, thereby driving the scraper 17 to move downward. When it is necessary to place the copper tape and film on the operating table 8, it is only necessary to pull the cross plate 21 upward to further compress the spring 22, so that the lower end of the scraper 17 can be moved away from the bottom surface of the operating table 8.

[0023] Furthermore, a re-pressing roller 23 is provided on the operating table 8, and the re-pressing roller 23 is rotatably connected to the operating table 8. After the copper strip and the film are pressed together by the rolling cylinder 13 and the scraper 17, the re-pressing roller 23 can further improve the bonding firmness and flatness between the film and the copper strip.

[0024] Furthermore, the film between the steering roller 11 and the rolling cylinder 13 is perpendicular to the copper belt on the operating table 8, so that when the film and the copper belt pass through the rolling cylinder 13, the gap between the film and the copper belt is large enough to facilitate the air between the film and the copper belt to be quickly squeezed and escaped by the rolling cylinder 13, which is beneficial to improving the quality of the copper-plastic belt.

[0025] Working principle: When in use, the first unwinding device 1 unwinds the copper tape, and the second unwinding device 2 unwinds the film. After the copper tape passes through the glue coating device 4, a glue layer can be coated on the upper surface of the copper tape. The copper tape and the film on the operating table 8 are close to each other, and then the first motor 14 controls the roller cylinder 13 to rotate. The roller cylinder 13 first rolls the film and the middle position of the copper tape, and while pressing the film and the copper tape, the air between the film and the copper tape is squeezed to the sides of the roller cylinder 13. Subsequently, the scraper 17 continues to squeeze the air moved to the sides of the roller cylinder 13 and between the film and the copper tape to the outside of the film, completing the pressing of the copper tape and the film, and then the re-pressing roller 23 further makes the copper tape and the film firmly bonded, and the winding device 3 winds up the pressed copper-plastic tape.

[0026] The device can first press the middle part of the film and the copper strip through the roller 13 and the scraper 17, and then press the side parts of the film and the copper strip, thereby extending the pressing time of the film and the copper strip at the same position, so that the air between the film and the copper strip at the same position has sufficient time to escape, thereby reducing the probability of bubbles appearing during the pressing process of the film and the copper strip, which is beneficial to improving the quality of the copper plastic strip.
