Technical Field
[0001] The utility model relates to the technical field of heat shrinkable film slitting, in particular to a light-controlled precision slitting machine for producing POF heat shrinkable films. Background Art
[0002] POF heat-shrinkable film is a packaging film made from polyolefins. It boasts high transparency, uniform shrinkage, and is non-toxic and environmentally friendly. It is widely used in the packaging of food, medicine, cosmetics, and electronic products. The use of a light-controlled precision slitting machine during production ensures that the film roll maintains precise width and neat edges during the high-speed slitting process. Photoelectric sensors monitor the film roll's position and edges in real time, and the control system adjusts the slitting parameters to improve slitting accuracy and efficiency, ensuring consistent product quality.
[0003] The existing POF heat shrink film light-controlled precision slitting machine is mainly composed of a frame, a reeling device, a photoelectric sensor, a slitting tool, a transmission device, a reeling device and a control system. The film roll is installed on the reeling device, and the film roll is driven to move by the transmission device. The photoelectric sensor detects the position and edge of the film roll in real time, and the control system adjusts the position of the slitting tool according to the sensor feedback to ensure accurate slitting. However, some existing POF heat shrink film light-controlled precision slitting machines do not take into account the problem that the POF heat shrink film lacks restrictions during the cutting process, which may cause deviation and affect cutting. Therefore, a light-controlled precision slitting machine for producing POF heat shrink film is proposed to solve the above problem. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a light-controlled precision slitting machine for producing POF heat shrinkable film, aiming to improve the problem in the prior art that the POF heat shrinkable film lacks restrictions during cutting, which may cause deviation and thus affect cutting.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A light-controlled precision slitting machine for producing POF heat shrink film, comprising a frame, a workbench fixedly connected to the interior of the frame, a limit assembly provided inside the workbench, the limit assembly being used to limit other components, a hydraulic rod 1 fixedly connected to the lower surface of the workbench, a lifting plate fixedly connected to the output end of the hydraulic rod 1, a cross-connection seat fixedly connected to the upper surface of the lifting plate, a connecting rod rotatably connected to the interior of the cross-connection seat, a rotating plate rotatably connected to the side wall of the connecting rod, a groove provided inside the rotating plate, a connecting block fixedly connected to the upper surface of the rotating plate, a fixing pin provided inside the connecting block, and a pressure wheel provided on the lower surface of the fixing pin;

The above structure improves the flexibility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Reference Figure 1-Figure 3 , The utility model provides an embodiment: a light-controlled precision slitting machine for producing POF heat shrink film, comprising a frame 1, a workbench 2 fixedly connected to the frame 1, a limit assembly provided inside the workbench 2, the limit assembly being used to limit other components, a hydraulic rod 5 fixedly connected to the lower surface of the workbench 2, a lifting plate 6 fixedly connected to the output end of the hydraulic rod 5, a cross-connection seat 7 fixedly connected to the upper surface of the lifting plate 6, a connecting rod 8 rotatably connected to the cross-connection seat 7, a rotating plate 9 rotatably connected to the side wall of the connecting rod 8, a groove 10 is provided inside the rotating plate 9, a connecting block 11 fixedly connected to the upper surface of the rotating plate 9, a fixing pin 12 is provided inside the connecting block 11, a pressure wheel 13 is provided on the lower surface of the fixing pin 12, a limit assembly comprising a limit shaft 3 and a limit ring 4, a side wall of the limit shaft 3 fixedly connected to the inside of the workbench 2, a side wall of the limit shaft 3 slidably connected to the inside of the groove 10, a side wall of the limit ring 4 fixedly connected to the side wall of the limit shaft 3, and the limit ring 4 fits with the side wall of the rotating plate 9;
[0031] When using the equipment to work, the operator needs to first evenly lay the POF heat shrink film on the top of the workbench 2, and then start the hydraulic rod 5 to push the lifting plate 6 to move downward. During the descent of the lifting plate 6, the rotating plate 9 is pulled to move by the connecting rod 8. At this time, the rotating plate 9 will slide on the limit shaft 3 through the groove 10 opened inside it. As the connecting rod 8 continues to pull, the rotating plate 9 gradually deflects and finally turns to a vertical position. During this process, the pressure wheel 13 will generate pressure on the surface of the POF heat shrink film, effectively restricting it to ensure that it can be firmly fixed after the rotating plate 9 turns to a vertical state.
[0032] Reference Figure 1-Figure 3, the frame 1 is fixedly connected to a hydraulic rod 2 14, the output end of the hydraulic rod 2 14 is fixedly connected to a moving frame 15, a turntable 19 is provided inside the moving frame 15, a photoelectric sensor 20 is provided on the lower surface of the turntable 19, a driving component is provided on the upper surface of the moving frame 15, and the driving component is used to drive the turntable 19 to rotate, a sliding rod 21 is fixedly connected to the inside of the moving frame 15, a slider 22 is slidably connected to the side wall of the sliding rod 21, a cutter 23 is provided on the lower surface of the slider 22, a fixed block 24 is fixedly connected to the upper surface of the slider 22, and a connecting plate 26 is rotatably connected to the side wall of the fixed block 24. The plate 26 is internally rotatably connected to a fixed block 25, and the upper surface of the fixed block 25 is rotatably connected to the lower surface of the turntable 19. The driving assembly includes a motor 16, a worm 17 and a worm wheel 18. The side wall of the motor 16 is fixedly connected to the upper surface of the moving frame 15, the side wall of the worm 17 is fixedly connected to the output end of the motor 16, and the worm wheel 18 is rotatably connected to the inside of the moving frame 15. The worm wheel 18 is engaged with the worm 17, and the photoelectric sensor 20 is electrically connected to the motor 16. The side wall of the turntable 19 passes through the side wall of the moving frame 15 and extends to the top. The side wall of the turntable 19 is fixedly connected to the lower surface of the worm wheel 18.
[0033] The photoelectric sensor 20 is a well-known technology that uses the photoelectric effect to detect and measure parameters such as the position, distance, and shape of an object. We will not elaborate on this in detail. After the POF heat shrink film is shrink-limited, the photoelectric sensor 20 determines the width of the POF heat shrink film to be cut. This information is then immediately transmitted to the motor 16. Upon receiving the signal, the motor 16 activates, driving the worm 17 to rotate. The rotation of the worm 17, in turn, drives the worm gear 18 to rotate synchronously. As the worm gear 18 rotates, the turntable 19 also rotates. This series of actions causes the fixed block 25 to begin moving. When the fixed block 25 begins to move, it also drives one side of the connecting plate 26 to move. At this time, the other side of the connecting plate 26 rotates on the fixed block 1 24, pulling the slider 22 to slide on the slide bar 21. This sliding process adjusts the distance between the cutter 23 and the cutter 23. After the adjustment is completed, the hydraulic rod 2 14 is activated, causing it to drive the moving frame 15 to descend, and the POF heat shrink film is finally cut by the cutter 23.
[0034] Working principle: When using this equipment to work, first lay the POF heat shrink film on the surface of the workbench 2, then start the hydraulic rod 5 to push the lifting plate 6 to move downward. When the lifting plate 6 moves downward, the connecting rod 8 will pull the rotating plate 9 to move. The rotating plate 9 will slide on the limit shaft 3 through the groove 10 at this time, and gradually deflect and turn to a vertical state, and make the pressing wheel 13 press on the surface of the POF heat shrink film to limit it. After the restriction is completed, the photoelectric sensor 20 is used to determine the width of the POF heat shrink film to be cut, and then send a signal to the motor 16 and When it is started, the motor 16 will drive the worm 17 to rotate and drive the worm wheel 18 to rotate. When the worm wheel 18 rotates, it further drives the turntable 19 to rotate, so that the fixed block 25 moves. When the fixed block 25 moves, it will drive one side of the connecting plate 26 to move. At this time, the other side of the connecting plate 26 will rotate on the fixed block 1 24 while pulling it to slide on the slide bar 21, thereby changing the distance between the cutters 23. After the distance is determined, the hydraulic rod 2 14 is started again to drive the moving frame 15 to descend, and the POF heat shrink film is cut by the cutter 23.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
