Technical Field
[0001] This utility model belongs to the field of packaging film cutting technology, specifically relating to a rust-proof and antistatic packaging film cutting device. Background Technology
[0002] A packaging film slitting device is a piece of equipment used to slit rolls of packaging film into multiple narrow rolls of packaging film according to specific sizes and requirements. It is widely used in industries such as packaging material processing, food, medicine, and daily necessities. It cuts wide packaging film raw materials (such as polyethylene, polypropylene and other plastic films, or composite films, aluminum foil films, etc.) into smaller rolls of film to meet the needs of different packaging scenarios (such as small packaging bags, label films, stretch films, etc.).
[0003] Some packaging films are cut into smaller parts of different specifications after being rolled up using a cutting device. Current cutting devices mainly place the rolled-up packaging film between two rollers and then cut it according to requirements. However, these cutting devices lack a positioning mechanism at both ends that can adapt to the actual length of the packaging film. This makes it impossible to effectively set up positioning mechanisms at both ends when dealing with packaging films of different lengths, resulting in inaccurate cutting lengths. Utility Model Content
[0004] The purpose of this invention is to provide a rust-proof and anti-static packaging film slitting device. This device addresses the problem that some packaging films, after being rolled up, are cut into smaller parts of different specifications using a cutting device. Current slitting devices primarily place the rolled-up packaging film between two rollers and then cut it according to requirements. However, these slitting devices lack a positioning mechanism at both ends that can adapt to the actual length of the packaging film. This makes it impossible to effectively set positioning mechanisms at both ends when dealing with packaging films of different lengths, resulting in inaccurate slitting lengths.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust-proof and antistatic packaging film cutting device, including a workbench, on which two mounting strips are symmetrically welded, one side of which is connected to a ground wire, and the other end of which is connected to the ground.
[0006] Two rollers are installed parallel to each other between the two mounting strips on opposite sides. A rectangular groove is formed through the worktable surface between the two rollers. Two positioning plates are movably installed in the middle of the rectangular groove. The bottom of the positioning plates is mounted on a screw. The two ends of the screw are respectively welded to the outer wall of one side of a fixing plate. The top side of the fixing plate is welded to the outer wall of the worktable. A slide is welded to the worktable surface on one side of the rollers. A cutting machine is movably installed on the surface of the slide.
[0007] In order to adjust the distance between the two positioning plates so that they can position and limit the ends of packaging films of different lengths, the rust-proof and antistatic packaging film cutting device of this utility model preferably has a bottom head welded to the bottom of the positioning plate, a through groove opened through the outer wall of the bottom head, a limiting cavity opened inside the through groove, an internal threaded sleeve movably installed inside the bottom head, the internal threaded sleeve being threaded onto the outer wall of the screw, and a positioning ring welded to the outer wall of the internal threaded sleeve;
[0008] The positioning ring is movably installed inside the limiting cavity, and the maximum diameter of the positioning ring is greater than the diameter of the through groove.
[0009] In order to enable the cutting machine to be positioned at different positions on the slide, as the rust-proof and antistatic packaging film cutting device of this utility model, preferably, a notch is provided on the outer wall of the slide away from the roller, a side plate is movably installed inside the notch, and the top of the side plate is welded to the outer wall of the cutting machine chassis.
[0010] An upper sliding groove is horizontally opened through one side of the outer wall of the side plate, and a lower sliding groove is also opened on the outer wall of the side plate below the upper sliding groove. The opening on one side of the upper sliding groove is aligned with the opening on one side of the recess.
[0011] A fixing button is threaded through the side plate of the upper slide groove. One end of the fixing button abuts against the inner wall of the recess. The lower slide groove is movably connected to one end of the L-shaped strip. The bottom of the L-shaped strip is welded to the surface of the worktable.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, adjust the two positioning plates to the two ends of the rectangular groove, and then place the packaging film to be cut between the two rollers. Next, move the positioning plates by adjusting the two internal threaded sleeves on the adjusting screw. This effectively moves the two positioning plates to the two ends of the packaging film to be cut, thus limiting the ends of the film during the cutting process and ensuring stability. The two positioning plates in this solution can be adjusted to fit the length of the packaging film, improving the positioning requirements for cutting packaging films of different lengths and thus enhancing the accuracy of the cut.

[0022] 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.
[0023] Please see Figure 1-6 The present invention provides the following technical solution: a rust-proof and anti-static packaging film cutting device, including a workbench 1, on which two mounting strips 2 are symmetrically welded on the surface of the workbench 1, one side of which is connected to a ground wire 10, and the other end of the ground wire 10 is connected to the ground.
[0024] When using the product, place the roll of packaging film with the cutting tool on the two rollers 3, then start the cutting machine 5 and pull the cutting part of the cutting machine 5 downwards, so that the cutting machine 5 can cut the roll.
[0025] Two rollers 3 are installed parallel to each other between two mounting strips 2 on opposite sides. A rectangular groove 6 is cut through the surface of the worktable 1 between the two rollers 3. Two positioning plates 7 are movably installed in the middle of the rectangular groove 6. The bottom of the positioning plate 7 is installed on the screw 8. The two ends of the screw 8 are respectively welded to the outer wall of one side of a fixing plate 9. The top side of the fixing plate 9 is welded to the outer wall of the worktable 1. A slide 4 is welded to the surface of the worktable 1 on one side of the rollers 3. A cutting machine 5 is movably installed on the surface of the slide 4.
[0026] The core components in this solution are all made of stainless steel, and the outer walls of other parts are coated with a layer of anti-rust paint, so that the equipment will not rust during use. This also prevents rust from falling onto the packaging film;
[0027] In addition, the ground wire 10 on the device will be connected to the ground during use, so that the static electricity generated by the device during use will be effectively guided to the ground, thereby preventing static electricity from adhering to the packaging film.
[0028] Preferably, the bottom of the positioning plate 7 is welded with a bottom head 71, a through groove 72 is opened through the outer wall of the bottom head 71, a limiting cavity 73 is opened inside the through groove 72, an internal threaded sleeve 81 is movably installed inside the bottom head 71, the internal threaded sleeve 81 is threadedly sleeved on the outer wall of the screw 8, and a positioning ring 82 is welded to the outer wall of the internal threaded sleeve 81.
[0029] The positioning ring 82 is movably installed inside the limiting cavity 73, and the maximum diameter of the positioning ring 82 is greater than the diameter of the through groove 72.
[0030] In practical use, when the internal threaded sleeve 81 rotates, it will move and rotate inside the bottom 71. In this way, the internal threaded sleeve 81 will synchronously drive the positioning ring 82 to rotate inside the limiting cavity 73. When the internal threaded sleeve 81 moves along the threaded trajectory of the screw 8, the positioning ring 82 will pull the limiting cavity 73 to move. When the limiting cavity 73 is pulled by the positioning ring 82, it will further drive the positioning plate 7 to move through the bottom 71. In this way, the two positioning plates 7 can be adjusted inside the rectangular groove 6.
[0031] When in use, the above structure allows the two positioning plates 7 to be effectively adjusted at both ends of the cut roll-shaped packaging film;
[0032] Preferably, a notch 41 is provided on the outer wall of the slide block 4 away from the roller 3, and a side plate 51 is movably installed inside the notch 41. The top of the side plate 51 is welded to the outer wall of the chassis of the cutting machine 5.
[0033] An upper sliding groove 52 is horizontally opened through one side of the outer wall of the side plate 51. A lower sliding groove 53 is also opened on the outer wall of the side plate 51 below the upper sliding groove 52. The opening on one side of the upper sliding groove 52 is aligned with the opening on one side of the recess 41.
[0034] A fixing button 55 is threaded through the side plate 51 at the upper slide groove 52. One end of the fixing button 55 abuts against the inner wall of the recess 41. It is movably connected to one end of the L-shaped strip 54 in the lower slide groove 53. The bottom of the L-shaped strip 54 is welded to the surface of the worktable 1.
[0035] When in use, the position of the cutting machine 5 on the slide 4 can be adjusted according to the required cutting length. After the adjustment is completed, the fixing button 55 is passed through the thread on the side plate 51 and tightened. In this way, one end of the fixing button 55 will be pressed against the inner wall of the recess 41, thereby completing the positioning of the cutting machine 5.
[0036] In addition, when the cutting machine 5 moves, it will drive the side plate 51. When the side plate 51 moves, it will drive the sliding groove 53 to move along the trajectory of the L-shaped strip 54. This can improve the consistency of the trajectory when the side plate 51 moves.
[0037] In practical use, the two positioning plates 7 are adjusted to the two ends of the rectangular groove 6, and then the packaging film to be cut is placed between the two rollers 3. Next, the positioning plates 7 are moved by the two internal threaded sleeves 81 on the adjusting screw 8. As the internal threaded sleeves 81 rotate, they move along the threaded path on the screw 8. Simultaneously, the rotation of the internal threaded sleeves 81 causes the positioning ring 82 to rotate in place inside the limiting cavity 73. Thus, the internal threaded sleeves 81, when rotating, pull the bottom head 71 horizontally via the positioning ring 82, and the movement of the bottom head 71 causes the positioning plates 7 to move.
[0038] In this way, the two positioning plates 7 can be effectively moved to both ends of the packaging film to be cut, thereby limiting the two ends of the packaging film during the cutting process and ensuring the stability of the cutting process. The two positioning plates 7 of this solution can be adapted and adjusted according to the length of the packaging film to be cut, making the equipment more convenient to use.
[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
