Abstract
Description
Technical Field
[0001] This invention belongs to the field of aluminum composite panel coating technology, specifically relating to an online automatic film tearing and winding method for an aluminum composite panel coating machine. Background Technology
[0002] In the continuous production process of aluminum composite panels, a protective film is usually applied to the surface of the panels to protect them. When product specifications change, the film material ages, or customers raise new requirements for the performance of the protective film, the original protective film on the surface of the aluminum composite panel needs to be removed and a new film that meets the requirements needs to be applied. Currently, this film removal and re-coating operation is mainly done manually.
[0003] Specifically, when the protective film needs to be replaced on the production line, operators must manually peel off the original protective film from the surface of the running aluminum composite panel and pull it continuously to separate it from the panel. More importantly, after the aluminum composite panel is manually peeled off, it needs to undergo a re-coating process, that is, it is transported to the inlet of the coating machine for a second coating. This intermittent operation mode of "peeling first, then transporting, then coating" has significant drawbacks: on the one hand, during the transport and reloading process, the surface of the aluminum composite panel frequently comes into contact with the roller conveyor, guide device, and operating environment, which can easily cause scratches, embossing, and other surface damage, seriously affecting the appearance quality and pass rate of the finished product; on the other hand, the entire process requires additional manual film peeling positions and transport and loading auxiliary personnel, which is labor-intensive, has low production efficiency, and is difficult to match with the speed of the continuous production line at the front end, causing the production line cycle to be interrupted.
[0004] Therefore, this invention proposes an integrated device and its usage method that can automatically remove and collect old film from aluminum composite panels online and directly connect them to subsequent lamination processes, in order to solve the problems of low efficiency, easy scratching of the panel surface, and the need for secondary lamination of existing manual film removal.

The top of the connecting rod 15 is threaded with a nut sleeve 17, and the top end of the connecting rod 15 passes through the frame 2. The top end of the nut sleeve 17 is rotatably connected to the frame 2.
[0023] In order to achieve automated and precise length cutting of the film material after lamination, and improve the cutting accuracy and work efficiency, in this embodiment, preferably, the film cutting assembly includes a mounting plate 18.

The slider 22 is slidably connected to the bottom of the mounting plate 18. A cutting blade 23 is fixed at the bottom of the slider 22.
[0024] In order to automatically correct and limit the aluminum composite panels during the conveying process and correct the problems of misalignment and deviation of the conveyed panels, in this embodiment, preferably, limit components are symmetrically installed at the feed end of the roller conveyor 1. The limit components include an adjusting cylinder 25 and a bracket 26. A guide cylinder 27 is fixed to the top of the bracket 26 near the roller. A connecting rod 24 is fixed to the output end of the adjusting cylinder 25. A push-pull rod 28 is fixed to the top of the connecting rod 24. The push-pull rod 28 passes through the guide cylinder 27 and a limit plate 29 is fixed to its end. Before step S1, a correction step is also included: the limiting plate 29 is driven to move towards each other by the adjusting cylinder 25 to center and limit the aluminum composite panels during conveying.
[0025] In summary, the overall equipment of this invention uses roller conveyor 1 as the conveying base and frame 2 as the overall mounting and supporting frame. Through the coordinated operation of the film-tearing assembly, film-coating assembly, film-cutting assembly integrated on the top of frame 2 and the limiting assembly at the feeding end of roller conveyor 1, it realizes the integrated continuous operation of the entire process of aluminum composite panel online automatic correction, old film removal, waste material winding, new film coating, and fixed-length film cutting. It requires no manual intervention and secondary handling of the panels, and can perfectly match the operating rhythm of continuous aluminum composite panel production lines. The specific working principle is as follows: During continuous production of aluminum composite panels, the first step is to correct the deviation: the panels are fed into the equipment's working area by the feed end of roller conveyor 1. Automatic deviation correction and positioning are achieved first through symmetrically arranged limiting components at the feed end. The limiting components are fixedly supported by bracket 26, with adjusting cylinder 25 as the driving power source. The output end of adjusting cylinder 25 is connected to a transmission rod, and a push-pull rod 28 is fixedly attached to the top of the rod. The push-pull rod 28 slides through the guide cylinder 27 at the top of bracket 26. The guide cylinder 27 provides precise guidance and prevents deviation during the extension and retraction of the push-pull rod 28. During operation, two sets of symmetrically distributed adjusting cylinders 25 extend and retract synchronously, driving the push-pull rod 28 to reciprocate linearly along the guide cylinder 27. This causes the fixed-end limiting plates 29 to finely adjust their spacing, clamping and limiting the aluminum composite panels during transport. This effectively corrects deviation and ensures that the aluminum composite panels are always transported stably and centered, providing a precise workstation foundation for subsequent film peeling and laminating processes, and guaranteeing subsequent processing accuracy.
[0026] After completing the alignment and positioning, the aluminum-plastic composite sheet is continuously conveyed forward by the roller conveyor 1 and enters the film-tearing step: the aluminum-plastic composite sheet enters the film-tearing assembly working area at the top of the frame 2. The film-tearing assembly consists of a passive unwinding roller 3, a first drive roller 4, and a waste material active winding roller 5 arranged sequentially along the conveying direction. The passive unwinding roller 3 and the waste material active winding roller 5 are fixedly installed on the top of the frame 2 by relying on the first bearing seat 13. Among them, the passive unwinding roller 3, the waste material active winding roller 5, and the subsequent passive unwinding roller 10 of the film material all adopt an assembly structure in which the roller body 11 and the end cover 12 are inserted and fastened with screws, which is convenient for disassembly and assembly, and facilitates the replacement of film rolls, equipment inspection and maintenance in the future. The end cover 12 at both ends of each roller body is equipped with a first bearing seat 13 on the outside, and is fixedly connected to the frame 2 through the first bearing seat 13 to ensure that each roller body rotates smoothly and runs stably without jamming. During the film removal operation, the passive unwinding roller 3 passively rotates to release the tape (ordinary film rolls and tapes are sufficient). Guided, tensioned, and driven by the first drive roller 4, the tape precisely adheres to the old protective film on the surface of the aluminum composite panel, utilizing the tape's adhesiveness to tightly bond with the old film. Simultaneously, the waste material active winding roller 5 provides a constant active winding tension, working in conjunction with the transmission of the first drive roller 4 to continuously and smoothly peel off the aged, expired, or non-compliant old protective film from the surface of the aluminum composite panel. The peeled old film waste is then uniformly wound up and stored by the waste material active winding roller 5, achieving a fully automatic and continuous old film removal operation.
[0027] After the old film is completely peeled off, the aluminum composite panel continues to be conveyed by roller conveyor 1 and enters the lamination step: the aluminum composite panel enters the lamination assembly work station to complete the automatic lamination operation of the new protective film; the lamination assembly consists of lamination pressing roller 6, second drive roller 7, and limit rod 8 arranged sequentially along the conveying direction; the top of the frame 2 is equipped with a passive unwinding roller 10 for releasing the new protective film; the new film material is passively unwound and output by the passive unwinding roller 10, and is guided, tensioned, and positioned by the second drive roller 7, smoothly conveying the film material to the working position of the lamination pressing roller 6; among them, the first drive roller 4, the lamination pressing roller 6, and the second drive roller 7 are all connected by a single drive roller 4. Both ends of the moving roller 7 are supported and installed via second bearing seats 14. A vertically arranged connecting rod 15 is fixed to the top of the second bearing seat 14. A spring 16 is sleeved on the body of the connecting rod 15, and a nut sleeve 17 is threaded onto the top end. The top end of the connecting rod 15 passes through the frame 2, and the nut sleeve 17 is rotatably connected to the frame 2. By rotating the nut sleeve 17, the extension and retraction height of the connecting rod 15 can be adjusted vertically. Combined with the elastic buffering effect of the spring 16, the elastic pressure of the film-coating roller 6 and the drive roller can be adaptively adjusted, so that the film material can be tightly and evenly bonded to the surface of the aluminum composite panel, avoiding problems such as wrinkling, blistering, and loose bonding, and ensuring the flatness and bonding accuracy of the film.
[0028] After the lamination process is completed, the film cutting step begins: the front end of the sheet material is conveyed to the film cutting assembly station to complete the automatic film cutting operation; the film cutting assembly uses the mounting plate 18 fixed at the bottom of the frame 2 as the supporting base. The bottom ends of the mounting plate 18 are respectively equipped with drive pulley 19 and driven pulley 20. A transmission belt 21 is fitted between the drive pulley 19 and the driven pulley 20. The transmission belt 21 is fixedly connected to the slider 22. The slider 22 slides with the bottom of the mounting plate 18. The cutting blade 23 is fixedly installed at the bottom of the slider 22. At the same time, the symmetrically arranged limiting rods 8 limit and constrain the two sides of the film material. The pressure rollers 9 at the bottom of the limiting rods 8 press and position the laminated film material to prevent the film material from shifting or loosening during the film cutting process.
[0029] During the film cutting operation, the drive pulley 19 rotates, driving the transmission belt 21 to circulate and drive the slider 22 to slide smoothly laterally along the bottom of the mounting plate 18, driving the cutting blade 23 at the bottom to move laterally at a uniform speed, and precisely cutting the film material after lamination, realizing independent lamination and cutting of a single aluminum composite panel, with high cutting accuracy and flat cut. The various processes of the overall equipment are arranged sequentially and seamlessly connected along the direction from the feed end to the discharge end of the roller conveyor 1. Through the coordinated linkage of each roller assembly, limiting assembly, and film cutting assembly, the online integrated continuous operation of aluminum composite panel correction, film tearing, winding, lamination, and film cutting is realized, without the need for machine stoppage or secondary handling of the board, perfectly adapting to the continuous production mode of the assembly line.
