Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, specifically a slitting equipment for film material production. Background Technology

[0002] Wine labels are tags affixed to wine bottles to identify relevant information about the wine. They are like the wine's "identity card," carrying a wealth of information to help consumers understand key details such as the wine's variety, origin, brewing process, and alcohol content. They are of great significance for consumers in selecting, tasting, and collecting wines. Most wine labels are made of PET film, PP film, or PVC film. Among them, labels made of PET film are widely favored by companies because of their advantages such as high tensile strength, high temperature resistance, high transparency, and good stability. After the PET film for wine labels is produced, it needs to be slit first, and then cut into appropriate sizes to facilitate the subsequent production of wine labels. Slitting equipment is required for this cutting process. Existing slitting equipment mostly requires manual collection of PET film after slitting. This means that manual collection is time-consuming and labor-intensive when performing batch cutting, and it also greatly increases the labor intensity of the workers. Summary of the Invention

[0009] Preferably, the limiting roller assembly consists of a driving roller and a driven roller. The driven roller is rotatably connected to the fixed frame.

[0011] Compared with the prior art, this utility model provides a slitting device for film material production, which has the following beneficial effects: 1. This utility model, when slitting PET film, uses a drive mechanism to drive the take-up roller to rotate, thereby conveying the PET film to the cutting table. Then, a pusher component drives the cutter to move laterally, cutting the PET film on the cutting table. Simultaneously, as the cutter moves, the rack follows the cutter. After the rack reaches the flipping component, the cutter finishes cutting the PET film on the cutting table. At the same time, the rack drives the flipping component to rotate, causing the cutting table to rotate 180 degrees. The slitting PET film on the cutting table then flips with the cutting table and falls off the cutting table under gravity. The pusher component then drives the cutter to return to its original position. During this process, the rack drives the flipping component to rotate in the opposite direction, causing the flipping component to return the cutting table to its original position. Then, through the cooperation of the drive mechanism and the take-up roller, the PET film on the take-up roller is fed back to the cutting table. This achieves the simultaneous slitting of PET film and automatic unloading of the cut PET film, greatly improving practicality and ease of use.

[0012] 2. In this utility model, when the push assembly drives the cutter to move, the lower pressure roller moves with the cutter. When the lower pressure roller moves, the spring presses down on the lower pressure roller. When the lower pressure roller moves, the lower pressure roller transmits the pressure force transmitted by the spring to the PET film on the cutting table. At this time, the PET film is pressed tightly, thereby improving the cutting effect of the cutter on the PET film.

[0013] 3. In this utility model, when the drive mechanism is running, the limiting mechanism can tension and limit the PET film on the take-up roller, thereby improving the cutting effect of the cutter on the PET film. At the same time, the limiting roller group in the limiting mechanism can also drive the PET film on the take-up roller to move towards the cutting table, thereby improving the smoothness of the PET film movement.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a slitting device for membrane material production.

[0018] Example 1: Please refer to Figures 1-6 A slitting device for film production includes a fixed frame 1, on which a plurality of staggered take-up rollers 2 are arranged. The fixed frame 1 is also equipped with a drive mechanism 3, a limiting mechanism 4 and a slitting mechanism 5. The drive mechanism 3 is used to drive the limiting mechanism 4 and the take-up rollers 2 to rotate. The slitting mechanism 5 includes a cutter 51, a cutting table 52, a pushing assembly 53, and several pressure rollers 54. The PET film on the take-up roller 2 passes through the limiting mechanism 4 and is distributed on the cutting table 52. The cutter 51 is used to cut the PET film on the cutting table 52. The pushing assembly 53 is used to drive the cutter 51 to cut the PET film laterally. The pressure rollers 54 are equipped with springs 542 and are used to press the PET film tightly when the cutter 51 is cutting. The cutting table 52 is also equipped with a flipping mechanism 6, which includes a rack 61 and a flipping component 62. When the cutter 51 moves, it can drive the rack 61 to move. When the rack 61 moves to the flipping component 62, the flipping component 62 can drive the cutting table 52 to flip 180 degrees.

[0019] In use, the take-up roller 2 is mounted on the fixed frame 1, and the PET film on the take-up roller 2 passes through the limiting mechanism 4. Then, the take-up roller 2 is driven to rotate by the drive mechanism 3. At this time, the PET film on the take-up roller 2 is conveyed to the cutting table 52 by the drive mechanism 3 and the limiting mechanism 4. Then, the user drives the cutter 51 to cut the PET film on the cutting table 52 laterally by pushing the component 53. When the cutter 51 moves, it drives the rack 61 and the pressure roller 54 to move synchronously. When the pressure roller 54 moves, the spring 542 presses down on the pressure roller 54. After the pressure roller 54 moves to the surface of the PET film, the pressure roller 54 transmits the pressure of the spring 542 to the PET film on the cutting table 52, thus achieving the pressing of the PET film, thereby improving the cutting effect of the cutter 51 on the PET film. When the cutter 51 cuts the PET film, the rack 61 is driven by the cutter 51 to move to the flipping component 62. As the cutter 51 moves, the rack 61 drives the flipping assembly 62 to rotate. The rotation of the flipping assembly 62 drives the cutting table 52 to rotate 180 degrees. At this time, the PET film that has been cut on the cutting table 52 rotates with the cutting table 52. Then, under the action of gravity, the PET film falls off the cutting table 52. After that, the push assembly 53 drives the cutter 51 to return to its position. During this process, the rack 61 drives the flipping assembly 62 to rotate in the opposite direction. At this time, the flipping assembly 62 drives the cutting table 52 to return to its position. Then, through the cooperation of the drive mechanism 3 and the take-up roller 2, the PET film on the take-up roller 2 is sent back to the cutting table 52 to achieve the re-cutting of the PET film. This realizes that while cutting the PET film, it can also automatically unload the cut PET film. In addition, during the cutting process of the cutter 51, the PET film can also be pressed, thereby improving the cutting effect of the PET film.

[0020] Example 2: See Figures 1-6 Unlike Embodiment 1 described above, the flipping assembly 62 includes a base 621, which is fixedly connected to the mounting frame 1. A rotating shaft 622 is rotatably connected to the base 621, with both ends of the shaft extending out of the base 621. A worm gear 623 is fixedly connected to one end of the shaft 622, and a worm 624 meshes with the outer side of the worm gear 623. The worm 624 is rotatably connected to the base 621, and a drive gear 625 is fixedly connected to the outer side of the worm 624. The rack 61 moves to the drive... When the gear 625 is in position, it can drive the drive gear 625 to rotate. The cutting table 52 is fixedly connected to the rotating shaft 622. The pushing component 53 includes a slide rail 531, which is fixedly connected to the fixed frame 1. A pneumatic slider 532 is slidably connected to the slide rail 531. The cutter 51 is installed on the pneumatic slider 532. A fixed plate 511 is also fixedly connected to the outside of the base 621. A cutter groove 512 is opened on the top surface of the fixed plate 511. The position of the cutter groove 512 corresponds to the cutter 51. The movement of the pneumatic slider 532 drives the cutter 51 to move along the slide rail 531. The movement of the cutter 51 drives the rack 61 to move. After the cutter 51 moves, it cuts the PET film with the help of the cutting groove 512. Then, the rack 61 meshes with the drive gear 625. As the cutter 51 moves, the rack 61 drives the drive gear 625 to rotate in the forward direction. The rotation of the drive gear 625 drives the worm gear 624 to rotate. The rotation of the worm gear 624 drives the worm wheel 623 to rotate. The rotation of the worm wheel 623 drives the rotating shaft 622 to rotate. The rotation of the rotating shaft 622 causes the cutting table 52 to rotate 180 degrees. At this time, the PET film that has been cut on the cutting table 52 falls off under the action of gravity. Then, the pneumatic slider 532 drives the cutter 51 to return to its original position. At this time, the rack 61 drives the drive gear 625 to rotate in the reverse direction. Similarly, the drive gear 625 drives the cutting table 52 to reset and perform the next round of cutting.

[0021] Example 3, see Figures 1-6 Unlike the second embodiment described above, the outer side of the pressure roller 54 is rotatably connected to the bracket 541. The pressure roller 54 is horizontally arranged inside the bracket 541. One end of the spring 542 is fixedly connected to the top of the bracket 541, and the other end of the spring 542 is fixedly connected to the pneumatic slider 532. The spring 542 is horizontally arranged on the top surface of the bracket 541. The top of the bracket 541 is also fixedly connected to the slide rod 543. The end of the slide rod 543 away from the bracket 541 extends out to the pneumatic slider 532. The slide rod 543 and the pneumatic slider 532 are slidably connected. The rack 61 is fixedly connected to the bracket 541. When the pneumatic slider 532 moves, it drives the cutter 51, the slide bar 543 and the bracket 541 to move. The movement of the bracket 541 drives the lower pressure roller 54 and the spring 542 to move. When the lower pressure roller 54 moves, the spring 542 presses the lower pressure roller 54 tightly onto the cutting table 52. After the lower pressure roller 54 moves onto the PET film, the spring 542 drives the lower pressure roller 54 to press the PET film tightly, thereby avoiding the problem of the PET film shifting when the cutter 51 cuts the PET film, which would affect the cutting effect.

[0022] Example 4, see Figures 1-6Unlike Embodiment 3 described above, the limiting mechanism 4 includes a limiting roller group 41, a lowering rod 42, an upper limiting roller 43, and a lower limiting roller 44. The limiting roller group 41, upper limiting roller 43, and lower limiting roller 44 are rotatably connected to the fixed frame 1 from left to right. The lowering rod 42 is mounted on the fixed frame 1 and is used to press down and tension the PET film. The limiting roller group 41 is spaced apart on the fixed frame 1 and consists of a driving roller 411 and a driven roller 412. The driven roller 412 is rotatably connected to the fixed frame 1. Supports 413 are rotatably connected to both ends of the driving roller 411, and the supports 413 are vertically slidably connected to the fixed frame 1. Tension springs 414 are fixedly connected to the sides respectively. The end of tension spring 414 away from support 413 is fixedly connected to the fixed frame 1. PET film is distributed between drive roller 411 and driven roller 412. Drive roller 411 and driven roller 412 can center and clamp PET film. Drive mechanism 3 includes motor 31. Motor 31 is fixedly connected to fixed frame 1. Gearbox 32 is fixedly connected to the output shaft of motor 31. Front transmission gear set 33 and rear transmission gear set 34 are respectively provided on the output shaft of gearbox 32. Front transmission gear set 33 is used to drive drive roller 411 in limit roller set 41 to rotate. Rear transmission gear set 34 is used to drive take-up roller 2 to rotate. After the take-up roller 2 is installed, the PET film on the take-up roller 2 is passed through the lower limit roller 44, the upper limit roller 43 and the limit roller group 41 in sequence. Then, the PET film is tensioned by the lower pressure rod 42. Then, the motor 31 drives the gearbox 32 to operate. The operation of the gearbox 32 drives the active roller 411 in the limit roller group 41 to rotate through the front transmission gear set 33. At the same time, the take-up roller 2 is driven to rotate synchronously through the rear transmission gear set 34. The rotation of the active roller 411 and the take-up roller 2, with the cooperation of the driven roller 412, transports the PET film on the take-up roller 2 to the cutting table 52, thereby completing the transport of the PET film. When the PET film passes through the limit roller group 41, the tension spring 414 can make the active roller 411 in close contact with the PET film, thereby improving the transport effect of the active roller 411 on the PET film.
