Description

Technical Field

[0001] The utility model relates to the technical field of plastic films, in particular to a positioning and transmission device for HF type composite film processing. Background Art

[0002] There are two ways to laminate plastic films during production. One is to apply a coating on the film surface, which becomes a uniform coating after drying to obtain a laminated film. The other is to apply an adhesive on the film surface before laminating the multi-layer film, and then bond the two adjacent layers of film together. Both of the above-mentioned laminating methods require the film to be flattened and the coating or adhesive to be applied to the film during the directional transmission of the film.

[0003] The existing patent (Announcement No.: CN218988376U) discloses a positioning and transmission device for composite film production, which has the effect of quickly adjusting the relative positions of two film rolls.

The adjustment of the four shafts at the same time is cumbersome, affecting subsequent use. Secondly, when in use, it will drive the composite film to move, and the composite film is prone to warping up during movement, resulting in wrinkles. Utility Model Content

[0030] A return spring 11 is connected to the inner side of the fixed block 10, and a movable block 12 is connected to the inner side of the return spring 11. The return spring 11 allows the movable block 12 to move freely to adapt to composite films of different thicknesses. A protective block 13 is connected to the inner side of the movable block 12, and a second sliding block 14 is connected to the side of the movable block 12. The second sliding block 14 is used to limit the movable block 12 to prevent it from deviating from the motion trajectory.

[0031] See the attached drawings in the specification Figure 1-4 A rotating shaft is also connected to the inner side of the bracket body 1, and the rotating shaft is connected to the winding shaft 5 in a rotating manner, and a driving structure is arranged on both sides of the rotating shaft, so that the winding shaft 5 can quickly wind up the composite film through the cooperation between the rotating shaft and the driving structure.

[0032] See the attached drawings in the specification Figure 1-4 The cylinder 2 is installed in an integrated manner with the bracket body 1. The cylinder 2 forms a piston moving structure with the linkage plate 4 through the piston rod 3. The linkage plate 4 and the push plate 7 are connected by hot melt connection. The cylinder 2 is used to drive the push plate 7 to move. On the one hand, the moving distance can be accurately controlled without a scale, and on the other hand, it ensures convenient operation.

[0033] See the attached drawings in the specification Figure 1-4 The push plate 7 is installed in an integrated manner with the first sliding rod 9. The first sliding rod 9 forms a sliding structure with the winding shaft 5 through the sliding groove 6. The push plate 7 is symmetrically distributed on both sides of the winding shaft 5. The winding shaft 5 and the push plate 7 are connected by the first sliding rod 9 to ensure that the push plate 7 does not affect the rotation of the winding shaft 5 when driving it to move.

[0034] See the attached drawings in the specification Figure 1-4 The fixed block 10 is connected to the positioning plate 8 by hot-melt connection. The fixed block 10 forms a spring reset structure with the movable block 12 through the reset spring 11. The movable block 12 is a trapezoidal structure. The fixed block 10 cooperates with the reset spring 11 so that the movable block 12 can adapt to composite films of different thicknesses.

[0035] See the attached drawings in the specification Figure 1-4 The movable block 12 and the second sliding block 14 are installed in an integrated manner. The protective blocks 13 are evenly and equidistantly distributed on the inner side of the movable block 12.

[0036] Working principle: When in use, first, when the position of the positioning plate 8 needs to be adjusted, turn on the switch of the cylinder 2, and the rear cylinder 2 drives the linkage plate 4 to move through the piston rod 3. When the linkage plate 4 moves, it drives the push plate 7 to move. The rear push plate 7 pulls the positioning plate 8 through the first sliding rod 9, so that the positioning plate 8 moves along the winding shaft 5 until it reaches a suitable position, and at the same time adjusts the position of the positioning plate 8 on the other side. When in use, the winding shaft 5 rotates through the driving structures on both sides thereof. When the composite film is wound and released, the positioning plate 8 slides with the first sliding rod 9, so that the push plate 7 is always in a constant position.

[0037] As mentioned above, when the positioning plate 8 moves, it drives the fixed block 10 and the movable block 12 to move. Since the movable block 12 is provided with a conical structure in the center direction of the winding shaft 5, the movable block 12 will move toward the fixed block 10 when it contacts the composite film. Due to the presence of the reset spring 11, the movable block 12 fits the composite film, so that the reset film will not be wrinkled when the positioning plate 8 moves.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
