Description
Technical Field
[0001] This utility model relates to the field of PVC film processing technology, and in particular to a double-sided embossing device for PVC film. Background Technology
[0002] PVC film is widely used in packaging, building materials, decoration and other fields due to its good flexibility, corrosion resistance and cost advantages.
[0003] Based on a comparison with existing technologies, most existing PVC film double-sided embossing devices adopt a design where two motors drive the upper and lower embossing rollers separately. This not only results in high energy consumption and complex structure, but also easily leads to misalignment of embossing textures due to asynchronous speeds of the two motors, affecting product quality. At the same time, the adjustment of the embossing roller gap in traditional devices mostly relies on direct bolt tightening. The adjustment process requires repeated machine stops for calibration, which is cumbersome and has low precision. It is difficult to adapt to the embossing requirements of PVC films of different thicknesses, thus reducing production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a double-sided embossing device for PVC film, which can achieve precise adjustment of the gap between the embossing rollers and is equipped with a highly efficient and synchronous recycling mechanism. This solves the problems of high energy consumption, cumbersome adjustment, and easy wrinkling during recycling of existing devices, thereby improving the quality and production efficiency of double-sided embossing of PVC film.
[0005] To achieve the above objectives, a double-sided embossing device for PVC film is provided, comprising a box body, an adjustment mechanism provided on the side of the box body, and a recycling device provided inside the box body; The adjustment mechanism includes a fixed plate, a motor fixedly connected to the lower end of the fixed plate, a rotating column fixedly connected to the upper end of the motor output shaft, a bevel gear one fixedly connected to the surface of the rotating column, an embossing roller one rotatably connected inside the housing, a bevel gear two fixedly connected to the side of the embossing roller one, a sliding groove one opened on the surface of the rotating column, a bevel gear three slidably connected inside the sliding groove one, a hollow column fixedly connected to the upper end of the bevel gear three, a sliding groove two opened on the side of the housing, a moving frame slidably connected inside the sliding groove two, an embossing roller two rotatably connected inside the moving frame, a bevel gear four fixedly connected to the side of the embossing roller two, a self-locking knob provided at the upper end of the housing, and a threaded rod fixedly connected to the lower end of the self-locking knob.
[0006] The recycling device includes a first conveyor wheel, which is connected to a second conveyor wheel via a transmission belt. A recycling roller is fixedly connected to the side of the second conveyor wheel.
[0007] The second bevel gear is positioned above the first bevel gear. The second bevel gear meshes with the upper end of the first bevel gear. Through the meshing of the second bevel gear with the upper end of the first bevel gear, when the first bevel gear rotates, it simultaneously drives the second bevel gear to rotate as well.
[0008] The fourth bevel gear is positioned at the lower end of the third bevel gear. The fourth bevel gear meshes with the lower end of the third bevel gear. Through the meshing of the fourth bevel gear with the lower end of the third bevel gear, when the third bevel gear rotates, it simultaneously drives the fourth bevel gear to rotate as well.
[0009] The hollow column is positioned inside the movable frame and is rotatably connected to the interior of the movable frame. This rotatable connection allows the hollow column to move up and down.
[0010] The threaded rod is positioned inside the movable frame and is threadedly connected to the inside of the movable frame. This threaded connection allows workers to easily adjust the gap of the embossing rollers.
[0011] The recycling roller is located inside the housing and is rotatably connected to the inside of the housing. This rotatable connection between the recycling roller and the inside of the housing makes the device operate more stably.
[0012] This utility model has the following beneficial effects: 1. Compared with existing technologies, the synchronous operation of the two embossing rollers is achieved through a motor and bevel gear transmission structure. At the same time, the adjustment mechanism adopts a combination design of "self-locking knob, threaded rod and moving frame". The operator only needs to turn the self-locking knob to drive the moving frame to slide up and down along the second sliding groove, thereby adjusting the gap between the second embossing roller and the first embossing roller. During the adjustment process, the third bevel gear can move synchronously along the first sliding groove, always maintaining the meshing state with the fourth bevel gear, ensuring uninterrupted power transmission and eliminating the need for repeated machine stops for calibration. This improves both the gap adjustment accuracy and production efficiency.
[0013] 2. Compared with existing technologies, the embossed PVC film is first smoothly conveyed by conveyor wheel one and conveyor belt, and then synchronously wound up by conveyor wheel two driving the recycling roller. The planar support of the conveyor belt can effectively prevent the film from wrinkling or shifting during the transmission process, and the rotational connection between the recycling roller and the box ensures the stability of the winding process. No manual assistance is required, which reduces labor costs, reduces the risk of film scratches, and improves product yield. Attached Figure Description

[0019] Reference Figure 1-4 This utility model embodiment provides a double-sided embossing device for PVC film, which includes a box body 1, an adjustment mechanism 2 provided on the side of the box body 1, and a recycling device 3 provided inside the box body 1. The adjusting mechanism 2 includes a fixed plate 21. A motor 22 is fixedly connected to the lower end of the fixed plate 21. A rotating column 23 is fixedly connected to the upper end of the output shaft of the motor 22. A bevel gear 24 is fixedly connected to the surface of the rotating column 23. An embossing roller 25 is rotatably connected inside the housing 1. A bevel gear 26 is fixedly connected to the side of the embossing roller 25. The bevel gear 26 is positioned above the bevel gear 24 and meshes with the upper end of the bevel gear 24. Through the meshing of the bevel gear 26 with the upper end of the bevel gear 24, the rotation of the bevel gear 24 simultaneously drives the bevel gear 26 to rotate. A sliding groove 27 is provided on the surface of the rotating column 23. A bevel gear 28 is slidably connected inside the sliding groove 27. A hollow column 29 is fixedly connected to the upper end of the bevel gear 28. The hollow column 29 is positioned inside the moving frame 211 and rotatably connected to the interior of the moving frame 211. A rotating connection is used to move the hollow column 29 up and down. A sliding groove 210 is provided on the side of the housing 1. A movable frame 211 is slidably connected inside the sliding groove 210. An embossing roller 212 is rotatably connected inside the movable frame 211. A bevel gear 213 is fixedly connected to the side of the embossing roller 212. The bevel gear 213 is positioned at the lower end of the bevel gear 28. The bevel gear 213 meshes with the lower end of the bevel gear 28. The lower end of the three gears 28 meshes, so that when the three bevel gears 28 rotate, they simultaneously drive the four bevel gears 213 to rotate as well. The upper end of the housing 1 is provided with a self-locking knob 214, and the lower end of the self-locking knob 214 is fixedly connected to a threaded rod 215. The threaded rod 215 is located inside the moving frame 211 and is threadedly connected to the inside of the moving frame 211. Through the threaded connection between the threaded rod 215 and the inside of the moving frame 211, it is convenient for the staff to adjust the gap of the embossing roller.
[0020] The recycling device 3 includes a first conveyor wheel 31, which is connected to a second conveyor wheel 32 via a transmission belt 33. A recycling roller 34 is fixedly connected to the side of the second conveyor wheel 32. The recycling roller 34 is located inside the housing 1 and is rotatably connected to the inside of the housing 1. This rotatable connection between the recycling roller 34 and the inside of the housing 1 makes the device operate more stably.
[0021] In use, first rotate the self-locking knob 214 at the top of the housing 1. Since the self-locking knob 214 is fixedly connected to the threaded rod 215, and the threaded rod 215 is threadedly connected to the inside of the moving frame 211, rotating the self-locking knob 214 can drive the threaded rod 215 to rotate synchronously, thereby pushing the moving frame 211 to slide up and down along the sliding groove 210. When the moving frame 211 slides, the hollow column 29 rotatably connected inside it will drive the bevel gear 28 to move synchronously along the sliding groove 27 on the surface of the rotating column 23, ensuring that the bevel gear 28 is always engaged with the bevel gear 213 on the side of the embossing roller 212, until the embossing roller 212 and the embossing roller 25 are engaged. When the gap is adjusted to match the film thickness, stop rotating the self-locking knob 214, and then start the motor 22 at the lower end of the fixed plate 21. The output shaft of the motor 22 drives the rotating column 23 to rotate, and the bevel gear 24 on the surface of the rotating column 23 rotates synchronously. Since the bevel gear 24 meshes with the bevel gear 26 on the side of the embossing roller 25, the bevel gear 24 will drive the bevel gear 26 and the embossing roller 25 to rotate. At the same time, the rotating column 23 drives the bevel gear 28 to rotate through the sliding groove 27. The bevel gear 28 then drives the embossing roller 212 to rotate through meshing with the bevel gear 213, realizing the synchronous reverse rotation of the embossing roller 25 and the embossing roller 212. The film is fed between two embossing rollers, and the patterns on the surfaces of the two embossing rollers are used to emboss both sides of the film. After embossing, the PVC film is output between the two embossing rollers and enters the conveyor belt 33 of the recycling device 3. The first conveyor wheel 31 drives the conveyor belt 33 to smoothly transport the film and avoid wrinkles. When the film is transported to the second conveyor wheel 32, the second conveyor wheel 32 drives the recycling roller 34 fixedly connected to the side to rotate, and synchronously rolls the embossed film onto the recycling roller 34, thus completing the entire embossing process.
