Description

Technical Field

[0001] This utility model relates to the field of adhesive film winding technology, specifically to an adhesive film winding mechanism. Background Art

[0002] The take-up section of the roll material processing production line mechanically winds raw materials into rolls. It is widely used in paper rolls, cloth rolls, plastic rolls, and metal roll processing production lines. It is designed in various ways according to actual process requirements. Common types include simple winding machines and hydraulic winding machines. Winding machines generally have strict requirements on the inner diameter, outer diameter, thickness, and width of the roll material. After the production of adhesive-backed films is completed, a winding mechanism is also used to package the adhesive-backed films.

[0003] Currently, factories use winding mechanisms to produce adhesive-backed films. To prevent uneven winding, limit plates are installed on the winding rollers. Since factories produce adhesive-backed films of different sizes, winding rollers of different sizes need to be replaced. Installation takes time, which affects the winding efficiency of the adhesive-backed films. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 - Figure 3 As shown, in this embodiment, an adhesive film winding mechanism includes a mounting frame 1. An adjustment box 5 is fixedly connected to one side of the bottom of the mounting frame 1. A second drive motor 11 is fixedly mounted in the middle of the upper end of the adjustment box 5. A drive gear 13 is rotatably connected to the middle of the adjustment box 5. The upper surface of the drive gear 13 is fixedly connected to the output end of the second drive motor 11. Two racks 14 mesh with the outer surface of the drive gear 13. A slider 15 is fixedly connected to one side of each of the two racks 14. A storage box 16 is fixedly connected to the upper end of each of the two sliders 15. The inner surfaces of the two storage boxes 16... The wall is slidably connected with racks 17, and one end of each rack 17 is fixedly connected to a limit baffle 18. When the drive motor 11 is turned on, the drive gear 13 drives the two racks 14 to slide on the drive motor 21, thereby bringing the two limit baffles 18 closer together and reducing the distance between them. When the drive gear 13 rotates in the opposite direction, the two limit baffles 18 can be moved away from each other, increasing the distance between them. This allows the take-up roller 7 to take up each type of adhesive film, improving the versatility of the equipment and the efficiency of adhesive film take-up.

[0022] like Figure 1 - Figure 3 As shown, the inner wall of the adjustment box 5 has two sliding grooves 12. Each of the two racks 14 is fixedly connected to one side of a sliding strip 19. The inner walls of the two sliding grooves 12 are slidably connected to the outer walls of the two sliding strips 19 respectively. The sliding strips 19 are used to limit the sliding of the racks 14 and prevent the sliding direction of the racks 14 from tilting.

[0023] like Figure 3 and Figure 4As shown, a mounting plate 22 is fixedly connected to one side of the outer wall of the storage box 16. A drive motor 21 is fixedly installed on one side of the mounting plate 22. The output end of the drive motor 21 is connected to a lifting gear 20. The outer wall of the lifting gear 20 meshes with one side of the rack 17. When the drive motor 21 is turned on, the lifting gear 20 rotates, causing the rack 17 to slide inside the storage box 16, thereby realizing the lifting and lowering of the limit baffle 18. When the winding roller 7 finishes winding, it is convenient to remove the adhesive film from the winding roller 7, thus improving the efficiency of the adhesive film winding.

[0024] like Figure 1 and Figure 2 As shown, a drive motor 2 is fixedly installed on one side of the mounting frame 1. The output end of the drive motor 2 is connected to a take-up roller 7, which is used to take up the adhesive film.

[0025] like Figure 1 and Figure 2 As shown, a connecting rod 6 is fixedly connected to one side of the inner wall of the mounting frame 1. Two rotating frames 10 are rotatably connected to the inner wall of the connecting rod 6. A pressure roller 8 is rotatably connected between the two rotating frames 10. The outer surface of the pressure roller 8 is in contact with the outer surface of the take-up roller 7. The operator lifts the pressure roller 8, places the adhesive film on the take-up roller 7, and then lowers the pressure roller 8. The pressure roller 8 presses the adhesive film down to prevent the adhesive film from being too loose during take-up.

[0026] like Figure 1 and Figure 2 As shown, a tension roller 9 is provided below the connecting rod 6. The two ends of the tension roller 9 are rotatably connected to the inner wall of the mounting frame 1. The tension roller 9 is used to tighten the adhesive film.

[0027] like Figure 1 - Figure 4 As shown, support feet 4 are fixedly connected to the four lower ends of the mounting bracket 1. A control device 3 is fixedly installed on the other side of the mounting bracket 1. One side of the control device 3 is electrically connected to one side of the drive motor 2, the drive gear 13 and the drive motor 21 respectively. The control device 3 is used to control how the drive motor 2, the drive gear 13 and the drive motor 21 cooperate.

[0028] This utility model provides an adhesive film winding mechanism, the specific working principle of which is as follows:

[0029] When winding the adhesive-backed film, the operator first lifts the pressure roller 8, places the adhesive-backed film on the winding roller 7, and then lowers the pressure roller 8, pressing the adhesive-backed film down. The dimensions of the adhesive-backed film to be produced are then input into the control device 3, and the second drive motor 11 is activated. The drive gear 13 drives two racks 14 to slide on the third drive motor 21, thereby bringing the two limit baffles 18 closer together, reducing the distance between them. When the drive gear 13 rotates in the opposite direction, it moves the two limit baffles 18 further apart, increasing the distance between them. This allows the winding roller 7 to handle each type of film. The adhesive film is wound up. At the same time, drive motor 21 is turned on to make the lifting gear 20 rotate, and the rack 17 slides in the storage box 16, thereby realizing the lifting and lowering of the limit baffle 18. Drive motor 21 is turned on until the inner wall of the limit baffle 18 is placed on the take-up roller 7. Drive motor 21 is turned off and drive motor 2 is turned on again. The take-up roller 7 winds up the adhesive film. When the winding is completed, drive motor 21 is turned on in the opposite direction to remove the limit baffle 18 from the take-up roller 7. The wound adhesive film is then removed from the take-up roller 7. The above operation is repeated to wind up the adhesive film.

[0030] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
