Description

Technical Field

[0001] This utility model relates to the field of plastic protective film production technology, specifically to a calendering equipment for producing plastic protective film. Background Technology

[0002] Plastic protective film is a film-like material that protects the surface of other materials. It is mainly made of polyolefins and is used for surface protection of various products with high surface condition requirements to prevent surface scratches, contamination and wear during handling, processing, storage and installation. This helps maintain the good appearance of the products and improves the product grade and yield.

[0003] In the prior art, in order to increase the production of plastic protective film, calendering equipment is used, and the production of plastic protective film can be increased by stretching equipment.

[0004] Utility Model Publication No. CN214926383U discloses a rubber sheeting calendering device, including a base. Two support columns are symmetrically welded to the top wall of the base. A top plate is welded to the top wall of the two support columns. A fixed roller is connected to both support columns. A groove is formed on one corresponding side of each support column. A cavity is formed inside the top plate. A thickness adjustment device is installed in the groove. A limit device is provided on the top plate. The thickness adjustment device includes two threaded blocks, which are slidably connected to the side wall of the groove. A threaded rod is threaded through each threaded block. This utility model, by setting up a synchronous pulley and synchronous belt, enables the two threaded rods to rotate synchronously through the action of the synchronous pulley and synchronous belt. This, in turn, drives the movable roller to move stably to a suitable position through the two threaded blocks, thereby adjusting the thickness of the calendered product.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example 1

[0025] This utility model provides, for example Figures 1-5As shown, a calendering equipment for producing plastic protective film includes: a support base 1, a winding mechanism 2 on the surface of the support base 1, a movable frame 3 on the surface of the support base 1, a reciprocating electric push rod 4 inside the movable frame 3, and a striking plate 5 on the lifting end of the reciprocating electric push rod 4; a vertical plate 6, a fixed roller 7 inserted inside the vertical plate 6, a lifting plate 8 on the side of the vertical plate 6, a lifting screw 9 screwed into the lifting plate 8, a first bearing 10 sleeved on the surface of the lifting screw 9, a positioning plate 11 on the outer ring surface of the first bearing 10, a drive motor 12 on the side of the positioning plate 11, a support rod 13 on the side of the positioning plate 11, a second bearing 14 sleeved at one end of the support rod 13, and a calendering roller 15 on the side of the second bearing 14;

[0026] First, the plastic protective film can be calendered by the cooperation of the fixed roller 7 and the calendering roller 15. Then, it is wound up by the winding mechanism 2. During the calendering process of the plastic protective film, the plastic protective film is first passed through the moving frame 3. Then, the reciprocating electric push rod 4 can be activated to make the striking plate 5 strike the surface of the plastic protective film, thereby reducing the hardness of the rubber before calendering and making it easier to calender the material using the fixed roller 7 and the calendering roller 15 in the future.

[0027] Example 2: Figures 1-3 As shown, a striking plate 5 is provided to facilitate the tapping of rubber to reduce its hardness. A rotating rod 16 is provided on the side of the moving frame 3. A traction wheel 17 is sleeved on the surface of the rotating rod 16. There are two sets of traction wheels 17, which are symmetrically distributed about the moving frame 3. The striking plate 5 is fixedly connected to the lifting end of the reciprocating electric push rod 4. A protective pad 18 is provided at the bottom of the striking plate 5.

[0028] More specifically, the friction between the material and the inside of the moving frame 3 can be reduced by rotating the two sets of traction wheels 17. Then, the reciprocating electric push rod 4 can be started to make the striking plate 5 reciprocate, so that the striking plate 5 can strike the rubber surface to reduce the hardness. The protective pad 18 can prevent the striking plate 5 from damaging the plastic protective film.

[0029] Example 3: Figure 4 and Figure 5As shown, a lifting screw 9 is provided to facilitate the calendering of plastic protective films of different thicknesses. The fixed roller 7 is rotatably connected to the upright plate 6. The upright plate 6 is fixedly connected to the surface of the support base 1. One end of the support rod 13 is fixedly connected to the inner ring surface of the second bearing 14. The transmission end of the drive motor 12 is fitted with a first gear 19. The surface of the lifting screw 9 is fitted with a second gear 20 and a first sprocket 21. The first gear 19 and the second gear 20 mesh and drive each other. There are two sets of lifting screws 9. The two sets of lifting screws 9 are symmetrically distributed about the fixed roller 7. The first sprocket 21 is fitted on both sets of lifting screws 9. The two sets of first sprockets 21 are chain driven by the chain 22. The lifting screw 9 is fixedly connected to the inner ring surface of the first bearing 10. The drive motor 12 is fixedly connected to the side of the positioning plate 11.

[0030] More specifically, the drive motor 12 can be started to drive the first gear 19 to rotate, and the meshing of the first gear 19 and the second gear 20 can drive the lifting screw 9 to rotate. Then, in conjunction with the chain 22 and the first sprocket 21, the two sets of lifting screws 9 can be driven to rotate, which can facilitate the downward movement of the calendering roller 15 and adjust the distance between the calendering roller 15 and the fixed roller 7, thus facilitating the calendering of plastic protective films of different thicknesses. Finally, the winding mechanism 2 is used to wind the film.
