Description

Technical Field

[0001] The utility model relates to the technical field of quantitative intercepting devices for film processing, and particularly relates to a quantitative intercepting device for film processing. Background Technique

[0002] The quantitative intercepting device for film processing is a device used in the process of film material processing, and its main function is to accurately cut and intercept the film material. This device is usually applied in industries such as electronics, packaging, optoelectronics, etc., and involves the processing of various film materials such as thin films, protective films, magnetic stripe films, etc. There are still some defects in the existing devices; for example;

[0003] For example, a quantitative intercepting device for brightening film processing with the publication number of CN219114204U, when it is used, includes an operating table. On both sides of the top surface of the operating table, side plates are respectively fixed. Arc-shaped openings are respectively formed on the side surfaces of the two side plates. First clamping grooves are respectively formed at the top and bottom of the inner side walls of the arc-shaped openings. Limiting components are respectively arranged in the two first clamping grooves. A flattening roller is rotatably connected between the two side plates. Fixed rods are respectively fixed at both ends of the top surfaces of the two side plates; the utility model enables the flattening roller to smooth the surface of the brightening film, so that the brightening film can be evenly laid on the top surface of the air collecting plate, which is convenient for the intercepting knife to intercept the brightening film. There are some problems with the above device. Although the device can be well applied when in use to complete the interception of the film, usually during the interception process, after the film is adsorbed on the air collecting plate by an air suction pump, the intercepting knife descends for interception. Since there are multiple ventilation holes on the surface of the air collecting plate and negative pressure is generated by an air extraction pump, part of the film will be sucked into the ventilation holes, resulting in the inability to be intercepted, making the use effect of the intercepting device difficult to reach the established expectation. Therefore, we propose a quantitative intercepting device for film processing to solve the above-mentioned problems. Content of the Utility Model

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution, a quantitative cutting device for film processing, including a body 1, the inside of the body 1 is fixedly connected to a first motor 2, and the first motor 2 is connected to a guide shaft 3, and the guide shaft 3 is connected to a first gear 4. Both the first gear 4 and the second gear 5 are connected to the guide shaft 3, and one end of the guide shaft 3 is rotatably connected to the inside of the body 1. The first gear 4 and the second gear 5 are meshed;

[0020] When in use, after passing the film through the middle position between the two guide shafts 3, the first motor 2 drives the guide shaft 3 to rotate, and at the same time drives the first gear 4 to rotate. Since the first gear 4 and the second gear 5 are meshed, the guide shafts 3 on both sides are driven to rotate synchronously at this time. While conveying the film through the guide shaft 3, the surface of the film can be smoothed;

[0021] Inside the machine body 1, a lead screw 6 is provided. The lead screw 6 is symmetrically arranged about the center of the first transmission belt 7. Above the lead screw 6, sliders 8 are connected. The sliders 8 are respectively fixedly connected to both sides of the moving plate 9. The lead screw 6 is connected to the first transmission belt 7, and the lead screw 6 is in threaded connection with the slider 8. The slider 8 is fixedly connected to the moving plate 9. The moving plate 9 is connected to the cutting knife 17 through a moving mechanism. The moving mechanism includes a second motor 10, a second transmission belt 11, a rotating shaft 12, a third gear 13, a first rack 14, a slide bar 15, a connecting rod 16, and a cutting knife 17. The second motor 10 is fixedly connected inside the moving plate 9. The second motor 10 is connected to the second transmission belt 11, and the second transmission belt 11 is connected to the rotating shaft 12. The rotating shaft 12 is rotatably connected inside the moving plate 9. The rotating shaft 12 is connected to the third gear 13, and the third gear 13 meshes with the first rack 14. The first rack 14 is slidably connected to the slide bar 15, and the slide bar 15 is fixedly connected inside the moving plate 9. The front end of the first rack 14 is fixedly connected to the connecting rod 16. The connecting rod 16 is slidably connected inside the moving plate 9. The front end of the connecting rod 16 is connected to the cutting knife 17. The first rack 14 is symmetrically arranged about the center of the third gear 13. The front ends of the first rack 14 are both connected to the connecting rod 16, and the front ends of the connecting rod 16 are both connected to the cutting knife 17. Above the machine body 1, a fixing mechanism is provided. The fixing mechanism includes a third motor 18, a fourth gear 19, a second rack 20, a pressing plate 21, and a fixing block 22. Above the machine body 1, it is fixedly connected to the fixing block 22. Inside the fixing block 22, the third motor 18 is fixedly connected. The third motor 18 is connected to the fourth gear 19. The fourth gear 19 meshes with the second rack 20. The second rack 20 is slidably connected inside the fixing block 22. The front end of the second rack 20 is fixedly connected to the pressing plate 21;

[0022] After one end of the film is conveyed to the lower part of the fixed block 22 on the right side of the machine body 1, the third motor 18 drives the fourth gear 19 to rotate. Since the fourth gear 19 meshes with the second rack 20, at this time, the second rack 20 slides inside the fixed block 22, and the second rack 20 drives the pressing plate 21 to descend. At this time, after the pressing plate 21 cooperates with the machine body 1 to fix the film, the position of the cutting knife 17 can be adjusted according to the required length to be intercepted. At this time, the lead screw 6 can be rotated, so that the lead screw 6 drives the first transmission belt 7 to rotate, making the lead screws 6 on both sides rotate synchronously. At this time, the lead screw 6 drives the slider 8 to move, and at the same time, the slider 8 drives the moving plate 9 to move. After moving the moving plate 9 to the specified position, the second motor 10 inside the moving plate 9 can be driven to drive the second transmission belt 11 to rotate. At this time, the second transmission belt 11 drives the rotating shaft 12 to rotate, so that the rotating shaft 12 drives the third gear 13 to rotate. Since the third gear 13 meshes with the first rack 14, the first racks 14 on both sides mesh. At this time, after the first rack 14 slides above the slide bar 15, the first rack 14 drives the connecting rod 16 to slide inside the moving plate 9. At this time, the connecting rod 16 drives the cutting knives 17 on both sides to move towards the middle to intercept the film.

[0023] Working principle: When using the quantitative intercepting device for membrane processing, during use, pass the membrane through the middle position between the two guiding shafts 3. Then, drive the guiding shafts 3 to rotate through the first motor 2, and at the same time drive the first gear 4 to rotate. Since the first gear 4 meshes with the second gear 5, at this time, drive the guiding shafts 3 on both sides to rotate synchronously. While transporting the membrane through the guiding shafts 3, the surface of the membrane can be smoothed. At this time, one end of the membrane is transported to the lower part of the fixed block 22 on the right side of the machine body 1. Then, drive the fourth gear 19 to rotate through the third motor 18. Since the fourth gear 19 meshes with the second rack 20, at this time, the second rack 20 slides inside the fixed block 22, and the second rack 20 drives the pressing plate 21 to descend. At this time, the pressing plate 21 cooperates with the machine body 1 to fix the membrane. At this time, the position of the intercepting knife 17 can be adjusted according to the required intercepted length. At this time, the lead screw 6 can be rotated, so that the lead screw 6 drives the first transmission belt 7 to rotate, making the lead screws 6 on both sides rotate synchronously. At this time, the lead screw 6 drives the slider 8 to move, and at the same time the slider 8 drives the moving plate 9 to move. After moving the moving plate 9 to the specified position, the second motor 10 inside the moving plate 9 can be driven to drive the second transmission belt 11 to rotate. At this time, the second transmission belt 11 drives the rotating shaft 12 to rotate, so that the rotating shaft 12 drives the third gear 13 to rotate. Since the third gear 13 meshes with the first rack 14, the first racks 14 on both sides mesh. At this time, the first rack 14 slides above the slide bar 15, and the first rack 14 drives the connecting rod 16 to slide inside the moving plate 9. At this time, the connecting rod 16 drives the intercepting knives 17 on both sides to move towards the middle to intercept the membrane, thus completing a series of operations.
