DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] First Embodiment

[0027] As attached Figure 1 Appendix Figure 2 With appendix Figure 3 As shown: A uniform embossing device includes a base plate 1, a conveying roller 2 and an embossing roller 3 disposed above the base plate 1. The conveying roller 2 can be used to convey the film, and the film will pass under the embossing roller 3, and the embossing roller 3 will complete the embossing work on the film.

[0028] The unfolding assembly 4, located to the left of the conveying roller 2 and the embossing roller 3, includes a set of U-shaped plates 401 positioned above the base plate 1 and an unfolding structure mounted on the U-shaped plates 401 for opening the pleated film. The unfolding structure of the unfolding assembly 4 includes a worm gear 402 mounted rotatably connected to each U-shaped plate 401. A motor 403 is mounted on the front side of each U-shaped plate 401, and the output end of each motor 403 is connected to one end of the worm gear 402. Two worm gears are engaged on each worm gear 402. The worm gear 404 has a rotating shaft 405 fixedly connected to one side. Each rotating shaft 405 has a rubber roller 406 fixedly connected to its outer surface. When the motor 403 is working, it drives the worm 402 to rotate, which in turn drives the worm gear 404 to rotate. The worm gear 404, through the transmission of the rotating shaft 405, causes the corresponding rubber rollers 406 located on the upper and lower sides of the film to rotate in opposite directions. The rotating rubber rollers 406 will stretch the wrinkled film, thereby flattening it before it enters the embossing process.

[0029] Each shaft 405 has a hanging plate 407 at its other end and on its outer surface. The ends of the two sets of hanging plates 407 that are far apart from each other are connected to the sides of the two U-shaped plates 401 that are close to each other. The hanging plates 407 can be used to hold and fix the shaft 405 and the worm gear 404, so that the worm gear 404 and the worm 402 can be stably meshed, thereby ensuring the smooth rotation of the rubber roller 406.

[0030] Each worm 402 has a reinforcing plate 408 on its outer surface. The ends of the two reinforcing plates 408 that are far apart from each other are respectively connected to the sides of the two U-shaped plates 401 that are close to each other. The reinforcing plates 408 can be used to reinforce the worm 402 and improve the stability of the worm 402 when it rotates.

[0031] Second Embodiment

[0032] As attached Figure 1 With appendix Figure 4As shown, based on the first embodiment: Adjustment component 5 is set on the front and rear sides of a set of U-shaped plates 401, used to adjust the distance between the U-shaped plates 401 to suit films of different thicknesses. Adjustment component 5 includes a set of motors 501 mounted on the upper surface of the base plate 1. The output end of each motor 501 is fixedly connected to a positive and negative threaded rod 502. The outer surface of each positive and negative threaded rod 502 is threaded with two moving blocks 503. The ends of each set of moving blocks 503 that are close to each other are respectively connected to the front and back of each U-shaped plate 401. By controlling the motors 501 to work synchronously, the moving blocks 503 on the positive and negative threaded rods 502 will synchronously drive the U-shaped plates 401 to move. The U-shaped plates 401 will then drive the rubber rollers 406 to move closer or further apart, thereby adjusting the spacing of the rubber rollers 406 to suit films of different thicknesses.

[0033] The top ends of the two positive and negative threaded rods 502 are jointly provided with a stabilizing plate 504. The stabilizing plate 504 can be used to connect the top ends of the positive and negative threaded rods 502, thereby enhancing the stability of the positive and negative threaded rods 502 when rotating.

[0034] A set of stabilizing rods 505 are fixedly connected to both the left and right sides of the stabilizing plate 504. A set of stabilizing blocks 506 are slidably connected to the outer surface of each stabilizing rod 505. The ends of each set of stabilizing blocks 506 that are close to each other are respectively connected to the front and back of each U-shaped plate 401. By using the cooperation of the stabilizing rods 505 and the stabilizing blocks 506, the U-shaped plate 401 can be stabilized, and the wobbling of the U-shaped plate 401 can be prevented when it moves.

[0035] Third Embodiment

[0036] As attached Figure 1 As shown: Based on the first and second embodiments, two holding rollers 6 are provided above the base plate 1. Both holding rollers 6 are located on the left side of the unfolding component 4. The holding rollers 6 can support the film and ensure the smooth movement of the film during the conveying process, avoiding any possible deviation, which is beneficial to the subsequent embossing process of the film.

[0037] Working principle: During use, the film is passed sequentially through the gap between the holding roller 6 and the channel between the conveying roller 2 and the embossing roller 3. As the conveying roller 2 conveys the film, the embossing roller 3 simultaneously completes the fine embossing work on the film. If wrinkles appear in the film during the conveying process, simply start the two motors 403 to make them run synchronously. The driving force of the motors 403 will drive the worm gear 402 to rotate, which in turn drives the worm wheel 404 to rotate. At the same time, the worm wheel 404, through the transmission of the rotating shaft 405, causes the corresponding rubber rollers 406 located on the upper and lower sides of the film to rotate in opposite directions. The rotating rubber rollers 406 will stretch the wrinkled film, thereby flattening it before it enters the embossing process, thus ensuring uniform embossing of the film.
