Description
Technical Field
[0001] This invention relates to the field of film production, and more particularly to an in-wall embossing and winding device for accordion film. Background Technology
[0002] Film machines typically produce smooth, unpatterned films. To add patterns, an embossing mechanism is needed for roll forming.
[0003] Patent application number CN202222218736.9 discloses a film embossing transmission structure, including a frame, a top beam fixedly mounted on the top of the frame, a base fixedly mounted on the bottom of the frame, rollers mounted on the bottom of the base, a release frame vertically fixed on one side of the front of the frame, the release frame being a smooth metal rod, a take-up frame vertically rotatably mounted on the other side of the front of the frame, the take-up frame being a metal rod with external splines on its surface, a take-up motor fixedly mounted on the back of the frame, the output end of the take-up motor being fixedly connected to the take-up frame, an embossing table horizontally mounted slightly above the release frame and the take-up frame, the embossing table being a metal table, the embossing table being fixedly connected to the frame, a heating device fixedly mounted on the bottom surface of the embossing table, an electric telescopic rod fixedly mounted in the middle of the top beam, and an embossing device mounted on the output end of the electric telescopic rod. However, this type of embossing involves embossing the film bag from the outside in, and the embossed pattern protrudes from the inside of the film bag, resulting in a lower coefficient of friction on the outer surface of the film bag. This makes it inconvenient to handle and stack. Furthermore, the film roll may deviate to some extent after production and winding. Directly embossing the wound film roll can easily lead to the scrapping of the packaging bags after production.
[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an accordion film in-mold embossing and winding device.
[0006] This invention can be achieved through the following technical solutions: This invention discloses an embossing and winding device for accordion film, comprising a frame, a traction turntable fixed at the bottom of the frame, a bracket rotatably connected to the traction turntable on the traction turntable, the bracket being driven to rotate by a rotary motor, an unwinding shaft placed on the bracket, a traction motor fixed on the bracket, a traction light roller fixed at the output end of the traction motor, a traction rubber roller on a bracket on one side of the traction light roller, an A-frame fixed on the frame above the bracket, an accordion tube fixed inside the A-frame, positioning rollers symmetrically arranged on both sides of the frame below the A-frame, an embossing device between the two positioning rollers, the embossing device comprising two symmetrical positioning plates, two support shafts fixed between the two positioning plates, and two support... Multiple support rollers are evenly arranged on the support shaft. An embossing shaft is fixed between two positioning plates below the support shaft. Multiple embossing rollers are evenly arranged on the embossing shaft. Embossing protrusions are evenly arranged on the embossing rollers. A connecting rod is fixed between the two positioning plates. A connecting plate is fixed on the connecting rod. A connecting shaft is fixed at both ends of the connecting plate. A connecting roller is arranged on each connecting shaft. A main conveyor roller is also arranged on the frame above the A-frame. The main conveyor roller is driven to rotate by a conveyor motor. A secondary conveyor roller is also arranged on the frame on one side of the main conveyor roller. A friction roller is also arranged on the frame. The friction roller is driven to rotate by a take-up motor. Limiting plates are arranged on the frames on both sides of the friction roller. A take-up shaft is placed between the two limiting plates.The unwinding spool of the wound film roll is placed on the support. After the film is pulled from the roll, it passes between the traction light roller and the traction rubber roller. Then, the cylindrical film passes between two positioning rollers. The embossing device is placed inside the cylindrical film. The positioning rollers, positioned between the support roller and the embossing roller, restrict the embossing device between the two positioning rollers. After passing through the embossing device, the film passes through the inside of the bellows barrel. The film with bellows folded at both ends continues to pass between the main conveyor roller and the secondary conveyor roller. The end of the film is fixed to the take-up spool. The take-up motor drives the friction roller to rotate, which in turn drives the take-up spool to rotate, ensuring that the film is evenly wound onto the take-up spool. When the film passes through the embossing device, the embossing roller is inside the cylindrical film. As the film passes through the embossing roller, it pulls the embossing roller to rotate, achieving the desired embossing effect. The embossing roller evenly presses patterns onto the inner wall of the film. When the film shifts, a sprocket is driven by a rotary motor to rotate. Because the sprocket meshes with the chain, the support rotates as the sprocket rotates, adjusting the position of the film roll pulled out. This ensures that the same position on the cylindrical film passes the embossing roller and that both ends of the same position on the film reach the gusseted tube position, ensuring that the gusseted position is consistent after edge insertion. This guarantees the quality of the packaging bags produced later and avoids the scrapping of packaging bags. This device uses an embossing shaft to perform embossing operations on the inner surface of the cylindrical film, ensuring that the embossed pattern protrudes from the inside of the film bag to the outside, thereby effectively increasing the friction coefficient of the outer surface of the film bag, facilitating the handling and stacking of the film bags. Furthermore, by rotating the support position, the consistency of the embossed and gusseted positions on the film bag is ensured, guaranteeing the quality of the film bag and preventing its scrapping.
[0007] Preferably, the bottom of the bellows tube has a circular opening, and the top of the bellows tube has a square opening. The two sides of the square opening have recessed rib structures extending from the square opening towards the circular opening. When the cylindrical film passes through the bellows tube, it is initially filled with gas. Due to the action of the main and secondary conveying rollers, the gas remains in the film below the bellows tube, expanding the film into a cylindrical shape. As the cylindrical film passes through the bellows tube, because one end of the bellows tube has a circular opening and the other end has a square opening, and because the inner wall of the bellows tube has ribs, the two ends of the film are folded into a bellows shape.
[0008] Preferably, a chain is fixed on the traction turntable, and a sprocket is fixed at the output end of the rotary motor, with the sprocket meshing with the chain.
[0009] Preferably, limit cylinders are fixed on the supports on both sides of the traction roller, and limit blocks are fixed to the piston rods of the limit cylinders. The limit blocks are set on the sides of the traction roller at corresponding positions and are rotatably connected to the limit blocks. After the film passes between the traction light roller and the traction roller, the limit cylinders are activated, the piston rods on the limit cylinders extend, and the traction roller pushes the film against the traction light roller.
[0010] Preferably, a gear is fixed to one side of the unwinding shaft, and a brake magnetic powder motor is also fixed to the bracket. A gear is also fixed to the output end of the brake magnetic powder motor, and the two gears mesh with each other. By setting up the brake magnetic powder motor, a constant tension is maintained during the unwinding of the film roll, preventing the film from breaking or loosening.
[0011] Preferably, multiple guide rollers are also provided on the frame between the main conveyor roller and the friction roller.
[0012] Compared with existing technologies, the present invention has the following advantages: This device uses an embossing shaft to perform embossing on the inner surface of a cylindrical film, ensuring that the embossed pattern protrudes from the inside of the film bag outwards. This effectively increases the coefficient of friction on the outer surface of the film bag, making it easier to handle and stack. Furthermore, by rotating the support position, it ensures that the embossing and accordion positions on the film bag are consistent, guaranteeing the quality of the film bag and preventing it from being scrapped.

[0014] like Figures 1 to 4As shown, this invention discloses an embossing and winding device for accordion film, including a frame 1. A traction turntable 2 is fixed at the bottom of the frame 1. A bracket 4 is rotatably connected to the traction turntable 2 on the traction turntable 2. The bracket 4 is driven to rotate by a rotary motor 7. A unwinding shaft 6 is also placed on the bracket 4. A traction motor 9 is also fixed on the bracket 4. A traction light roller 10 is fixed at the output end of the traction motor 9. A traction rubber roller 13 is also set on the bracket 4 on one side of the traction light roller 10. An A-frame 14 is also fixed on the frame 1 above the bracket 4. An accordion tube 15 is fixed inside the A-frame 14. Positioning rollers 19 are symmetrically arranged on both sides of the frame 1 below the A-frame 14. An embossing device 20 is also arranged between the two positioning rollers 19. The embossing device 20 includes two symmetrical positioning plates 21. Two support shafts 22 are fixed between the two positioning plates 21. Both support shafts 22 are also equipped with... Multiple support rollers 23 are evenly arranged. An embossing shaft 24 is fixed between two positioning plates 21 below the support shaft 22. Multiple embossing rollers 25 are evenly arranged on the embossing shaft 24. Embossing protrusions are evenly arranged on the embossing rollers 25. A connecting rod 26 is fixed between the two positioning plates 21. A connecting plate 27 is fixed on the connecting rod 26. A connecting shaft 28 is fixed at both ends of the connecting plate 27. A connecting roller 30 is arranged on the connecting shaft 28. A conveying main roller 32 is also arranged on the frame 1 above the herringbone frame 14. The conveying main roller 32 is driven to rotate by a conveying motor 31. A conveying secondary roller 33 is also arranged on the frame 1 on one side of the conveying main roller 32. A friction roller 35 is also arranged on the frame 1. The friction roller 35 is driven to rotate by a winding motor 36. A limit plate 37 is arranged on the frame 1 on both sides of the friction roller 35. A winding shaft 38 is placed between the two limit plates 37.The unwinding shaft 6, with the film roll wound up, is placed on the support 4. After the film is pulled out from the film roll, it passes between the traction light roller 10 and the traction rubber roller 13. Then, the barrel-shaped film passes between the two positioning rollers 19, and the embossing device 20 is placed inside the barrel-shaped film. The positioning rollers 19, positioned between the support roller 23 and the embossing roller 25, restrict the embossing device 20 between the two positioning rollers 19. After passing through the embossing device 20, the film passes through the inside of the bellows barrel 15. The film is folded at both ends by the bellows inside the bellows barrel 15. The film with folded ends continues to pass between the main conveyor roller 32 and the secondary conveyor roller 33. The end of the film is fixed on the take-up shaft 38. The take-up motor 36 drives the friction roller 35 to rotate, which in turn drives the take-up shaft 38 to rotate, so that the film is evenly wound on the take-up shaft 38. When the film passes through the position of the embossing device 20, the embossing roller 25 is inside the barrel-shaped film. The film passes through the embossing roller 20. At 5 o'clock, the film pulls the embossing roller 25 to rotate, so that the embossing roller 25 can evenly press the pattern on the inner wall of the film. When the film deviates, the sprocket 8 is driven to rotate by the rotary motor 7. Since the sprocket 8 is engaged with the chain 3, when the sprocket 8 rotates, the bracket 4 rotates to adjust the position of the film pulled out of the film roll. This ensures that the same position on the cylindrical film passes the embossing roller 25 and that both ends of the same position on the film reach the position of the gusset tube 15. This ensures that the gusset position after the edge is inserted is consistent, thereby ensuring the quality of the packaging bags produced in subsequent production and avoiding the scrapping of packaging bags. This device sets the embossing shaft 24 to perform embossing operations on the inner surface of the cylindrical film, ensuring that the embossed pattern protrudes from the inside of the film bag to the outside, thereby effectively increasing the friction coefficient of the outer surface of the film bag, making it easier to pick up and stack the film bags. Furthermore, by rotating the position of the bracket 4, the embossing and gusset positions on the film bag are consistent, ensuring the quality of the film bag and avoiding the scrapping of the film bag.
[0015] The bellows tube 15 has a circular opening 16 at the bottom and a square opening 17 at the top. The two sides of the square opening 17 have recessed ribs 18 extending from the square opening 17 towards the circular opening 16. When the cylindrical film passes through the bellows tube 15, it is initially filled with gas. Due to the action of the main conveying roller 32 and the secondary conveying roller 33, the gas remains in the film below the bellows tube 15, expanding the film into a cylindrical shape. As the cylindrical film passes through the bellows tube 15, because one end of the bellows tube 15 has a circular opening 16 and the other end has a square opening, and because the inner wall of the bellows tube 15 has ribs 18, the two ends of the film are folded into a bellows shape.
[0016] Among them, a chain 3 is fixed on the traction turntable 2, and a sprocket 8 is fixed at the output end of the rotary motor 7. The sprocket 8 meshes with the chain 3.
[0017] In this system, limit cylinders 11 are fixed on the brackets 4 on both sides of the traction roller 13. Limit blocks 12 are fixed to the piston rods of the limit cylinders 11. Limit blocks 12 are set on the limit blocks 12 at corresponding positions on both sides of the traction roller 13 and are rotatably connected to the limit blocks 12. After the film passes between the traction light roller 10 and the traction roller 13, the limit cylinders 11 are activated, the piston rods on the limit cylinders 11 extend, and the traction roller 13 pushes the film against the traction light roller 10.
[0018] Among them, multiple guide rollers 34 are also provided on the frame 1 between the main conveyor roller 32 and the friction roller 35. Example
[0019] This embodiment discloses an accordion film in-wall embossing and winding device. Based on the structure and principle of Embodiment 1, this embodiment has a gear fixed on one side of the unwinding shaft 6, and a brake magnetic powder motor 5 fixed on the bracket 4. A gear is also fixed to the output end of the brake magnetic powder motor 5, and the two gears mesh with each other. By setting the brake magnetic powder motor 5, a constant tension is maintained during the unwinding of the film roll, preventing the film from breaking or loosening.
[0020] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
