DETAILED DESCRIPTION
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution: a film winding device for facilitating tension adjustment, including: a bottom plate 1, a motor 2, a vertical plate 3, a rotating roller 4, a winding drum 5, a connecting block 6, a fixed frame 7, an adapter block 8, a clamping block 9, a first spring 10, a first connecting plate 11, an upper cleaning roller 12, a lower cleaning roller 13, a slider 14, a second spring 15, a mounting plate 16, a second connecting plate 17, an adjusting cylinder 18, an adjusting rod 19, a third spring 20, a lead screw 21, a moving block 22, a limiting rod 23 and a baffle 24.
[0030] When using the film winding device for facilitating tension adjustment, first as Figure 1 , Figure 2 and Figure 3 shown, the motor 2 is fixedly installed on the upper surface of the left end of the bottom plate 1, the vertical plate 3 is installed on the upper side of the left part of the bottom plate 1, and there are two vertical plates 3 symmetrically arranged along the central axis of the bottom plate 1. The front vertical plate 3 is fixed to the upper end of the bottom plate 1, and the rear vertical plate 3 moves above the bottom plate 1. The lower end of the rear vertical plate 3 is fixedly connected to the connecting block 6, and the connecting block 6 is slidably connected to the cavity opened in the rear section of the bottom plate 1. Circular through grooves are symmetrically opened on the inner sides of the left and right parts of the connecting block 6, and the clamping block 9 is snap-connected to the inside of the connecting block 6. The upper end of the clamping block 9 is fixedly connected to the lower end inside the adapter block 8, and the clamping block 9 is slidably connected to the bottom plate 1. The lower end of the outside of the adapter block 8 is fixed to the bottom plate 1 through the first spring 10, and the adapter block 8 is slidably connected to the inside of the fixed frame 7 fixedly connected to the bottom plate 1;
[0031] Slide the winding drum 5 along the semi-cylindrical groove fixed on the outside of the rotating roller 4, which can improve the connection stability between the winding drum 5 and the rotating roller 4. Lift the adapter block 8 upward, at this time the first spring 10 undergoes elastic deformation, then move the rear vertical plate 3 to the left, and then move the vertical plate 3 forward. At this time, the vertical plate 3 is sleeved on the outside of the rear end of the rotating roller 4. Release the adapter block 8 so that the first spring 10 restores elastic deformation to drive the clamping block 9 to snap into the inside of the connecting block 6, completing the fixation of the vertical plate 3 to the bottom plate 1. When starting the motor 2, drive the rotating roller 4 to rotate by the belt drive on its outside. At this time, the rotating roller 4 drives the winding drum 5 to rotate inside the vertical plate 3 to wind the film. Among them, the disassembly and assembly process of the winding drum 5 is simple and fast, greatly saving the working time and energy.
[0032] As Figure 1And Figure 5 As shown in Figure 5 , the first connecting plate 11 is fixedly installed on the upper right side of the bottom plate 1. The upper inner side of the first connecting plate 11 is rotatably connected with an upper cleaning roller 12. A lower cleaning roller 13 is arranged below the upper cleaning roller 12. The front and rear ends of the lower cleaning roller 13 are rotatably connected to the inner side of the slider 14. The slider 14 is slidably connected to the inner side of the first connecting plate 11. The lower end of the slider 14 is connected to the first connecting plate 11 through a second spring 15;
[0033] Pull the lower cleaning roller 13 downward to cause elastic deformation of the second spring 15. Pass the film through between the upper cleaning roller 12 and the lower cleaning roller 13. Release the lower cleaning roller 13 to make the second spring 15 recover elastic deformation and push the slider 14 upward. At this time, the upper cleaning roller 12 and the lower cleaning roller 13 are respectively attached to the upper and lower surfaces of the film. When the film moves, the upper cleaning roller 12 and the lower cleaning roller 13 rotate, and the fluff on their outer surfaces adsorbs the dust on the film.
[0034] As Figure 1 And Figure 4 As shown in Figure 4 , the mounting plate 16 is fixedly installed on the upper end of the bottom plate 1. The upper right side of the mounting plate 16 is fixedly connected to the second connecting plate 17. The adjusting cylinder 18 is rotatably connected to the outer middle part of the adjusting rod 19. The front and rear ends of the adjusting rod 19 are slidably connected to the inner side of the second connecting plate 17. Third springs 20 are sleeved on the outer sides of the front and rear ends of the adjusting rod 19. The upper and lower ends of the third spring 20 are respectively fixedly connected to the second connecting plate 17 and the adjusting rod 19;
[0035] Pass the film through below the adjusting cylinder 18. The surface of the adjusting cylinder 18 is attached to the upper surface of the film. When the film is wound up, the adjusting cylinder 18 and the adjusting rod 19 move up and down through the elastic action of the third spring 20 to ensure that the film is always pressed by the adjusting cylinder 18 to maintain a tensioned state, and the film tension can be automatically adjusted according to the progress of the film winding, avoiding wrinkles on the outer side of the winding cylinder 5, protecting the integrity of the film surface, and facilitating the subsequent access to the formed winding cylinder 5;
[0036] The lead screw 21 is rotatably connected to the inner side of the mounting plate 16. The moving block 22 is rotatably connected to the outer side of the lead screw 21. The upper end of the moving block 22 is fixedly connected to the baffle 24. The left and right parts of the moving block 22 are slidably connected to the outer side of the limiting rod 23. Both ends of the limiting rod 23 are fixedly connected to the mounting plate 16;
[0037] Before the film is wound up, observe the width of the film. Rotate the lead screw 21 to control the two side moving blocks 22 to move towards each other, so that the baffle 24 is attached to the side of the film. At this time, the limiting rod 23 restricts the movement direction of the moving block 22, restricting the film to be wound in the middle of the winding cylinder 5, improving the aesthetics of the formed winding cylinder 5, and facilitating the subsequent storage and access of the film.
