Description

A high-precision adjustable half-cut slitting device for privacy films Technical Field

[0001] This utility model relates to the field of privacy film production technology, and in particular to a high-precision adjustable half-cut slitting device for privacy films. Background Technology

[0002] Semi-slitting devices are used for processing flexible materials such as films and paper. By precisely controlling the cutting depth of the blades, they cut only through the surface layer or part of the structure of the material (without cutting through the bottom layer) and simultaneously cut the material into strips of a specified width. They are characterized by high precision and strong adjustability and are widely used in industries such as electronics, optics, and packaging to meet the process requirements of semi-slitting flexible materials. Semi-slitting devices are particularly widely used in the production of privacy films.

[0003] In the existing technology, when the blade is adjusted in the semi-sliding device, the blade can slide freely in the position of the shaft and be fixed with bolts after being adjusted to the required width. However, when the blade is adjusted laterally, the fine adjustment of the blade position requires a rubber hammer to tap and adjust it, and it is not easy to adjust it to the precise position. At the same time, the adjustment of the blade with additional tools increases the workflow and is inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision adjustable half-cut slitting device for privacy films.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision adjustable slitting device for privacy films includes a device body. A mounting plate is fixedly connected to the top center of the device body. Bearing seats are fixedly connected to both sides of the top of the mounting plate. Rollers are fixedly connected to the two ends of the inner center of the two bearing seats. Roller bodies are fixedly connected to the adjacent side of the two rollers. Roller rests are fixedly connected between the two roller bodies. A common main shaft is fixedly connected between the two roller rests. A rectangular groove is opened at the top of the main shaft, and a common guide rod is fixedly connected between the two ends of the rectangular groove. Slider blocks are slidably sleeved at both ends of the guide rod. Circular holes adapted to the guide rods are opened at the bottom of the two sliders. Rectangular holes are opened in the middle of the two sliders. Locking mechanisms for locking the sliders are provided in the two rectangular holes.

[0007] Preferably, the locking mechanism includes four rectangular side blocks fixedly connected to both ends of the rectangular hole. Each rectangular side block has a U-shaped rod slidably fitted inside it, and each rectangular side block has a round hole adapted to the U-shaped rod. The same pressing block is fixedly connected to the outer side of the two U-shaped rods at the same end. Multiple anti-slip strips are fixedly connected to the sides of the two pressing blocks that are far apart from each other. Fixed plates are fixedly connected to the sides of the two pressing blocks that are close to each other, and the two fixed plates are staggered. Both fixed plates have oblique holes with opposite directions. The locking mechanism facilitates cooperation with the rubber pad to lock the slider and the cutter.

[0008] Preferably, each slider is slidably fitted with a T-shaped pull rod at the top of the rectangular hole, and both sliders have square holes adapted to the T-shaped pull rods. Both bottom sides of the two T-shaped pull rods are fixedly connected with protruding rods, and each protruding rod is slidably connected in adjacent oblique holes. The top of the T-shaped pull rod has a horizontal hole. The locking mechanism is controlled by raising and lowering the T-shaped pull rod.

[0009] Preferably, a driving mechanism is provided at the top of the two sliders near the horizontal hole. The driving mechanism includes an N-shaped plate fixedly connected to the top of the slider near the horizontal hole. A rotating rod is rotatably sleeved on the N-shaped plate near the bottom. The two ends of the rotating rod are fixedly connected to the same U-shaped push rod. A limiting wheel is fixedly sleeved in the middle of the rotating rod, and multiple slots are opened on the circumferential surface of the limiting wheel. The two ends of the bottom of the U-shaped push rod are fixedly connected to the same driving rod, and the driving rod is slidably connected in the adjacent horizontal holes.

[0010] Preferably, the driving mechanism further includes a T-shaped rod slidably sleeved at the middle of the top of the N-shaped plate. The top of the N-shaped plate has a square hole adapted to the T-shaped rod. The bottom of the T-shaped rod is fixedly connected to the T-shaped plate, and the bottom of the T-shaped plate is adapted to the groove of the limiting wheel. A spring is sleeved on the T-shaped rod at the bottom of the N-shaped plate. Through the cooperation between the T-shaped plate and the limiting wheel, the U-shaped push rod is locked to prevent it from loosening during operation.

[0011] Preferably, the inner wall of the rectangular groove is provided with strip grooves on both sides, and a rubber pad is fixedly connected in each strip groove, and the rubber pad is adapted to the anti-slip strip.

[0012] Preferably, both ends of the main shaft are slidably fitted with cutters, each cutter has a fixing hole at its top, each fixing hole is provided with a fastening bolt, and each fastening bolt is screwed to the adjacent slider. Each slider has a threaded hole at its top that matches the fastening bolt. The fastening bolts facilitate the fixing and disassembly of the cutter and the slider.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing a locking mechanism, T-shaped pull rod, U-shaped push rod, drive rod, and rubber pad, the U-shaped push rod controls the T-shaped pull rod to operate the locking mechanism, thereby controlling the separation and compression of the anti-slip strip and the rubber pad. This allows the cutter to move and be fixed quickly and easily with the slider, eliminating the need for additional tools. This effectively solves the problem of inconvenient cutter position adjustment mentioned in the background technology, achieving rapid and convenient adjustment and stable fixing of the cutter position. This significantly improves the operating efficiency and flexibility of the slitting device. At the same time, the compression and fixing of the anti-slip strip and the rubber pad enhances the stability of the cutter during operation, ensuring slitting accuracy, reducing manual adjustment costs, and meeting the requirements of high-precision slitting processes for rapid response and precise control of the equipment.

[0015] 2. Through the cooperation of T-shaped plate, limit wheel and T-shaped rod, the U-shaped push rod will not loosen on its own when there is no manual operation, ensuring the stability of the cutter and slider during operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Referring to Figures 1-7, a high-precision adjustable half-cut slitting device for privacy films includes a device body 1. A mounting plate 2 is fixedly connected to the top center of the device body 1. Bearing seats 3 are fixedly connected to both sides of the top of the mounting plate 2. Roller shafts 4 are fixedly connected to both ends of the inner center of the two bearing seats 3. Roller bodies 501 are fixedly connected to the sides of the two roller shafts 4 that are close to each other. Roller rests 5 are fixedly connected between the two roller bodies 501. A single main shaft 6 is fixedly connected between the two roller rests 5. A rectangular opening is formed at the top of the main shaft 6. The rectangular groove 601 is fixedly connected to the same guide rod 603 at both ends. Slider 7 is slidably sleeved at both ends of the guide rod 603. The bottom of each slider 7 is provided with a round hole that matches the guide rod 603. The middle of each slider 7 is provided with a rectangular hole 701. A locking mechanism 8 for locking the slider 7 is provided in each of the two rectangular holes 701. Through the compression deformation of the anti-slip strip 804 of the locking mechanism 8 and the rubber pad 602, the slider 7 will not slide in its position.

[0026] In this utility model, the locking mechanism 8 includes four rectangular side blocks 801 that are respectively fixedly connected to both ends of the rectangular hole 701. Each rectangular side block 801 is slidably fitted with a U-shaped rod 802. Each rectangular side block 801 has a round hole that matches the U-shaped rod 802. The same pressing block 803 is fixedly connected to the outer side of the two U-shaped rods 802 at the same end. Multiple anti-slip strips 804 are fixedly connected to the side of the two pressing blocks 803 that are far apart from each other. A fixing plate 805 is fixedly connected to the side of the two pressing blocks 803 that are close to each other. The two fixing plates 805 are staggered. An oblique hole 806 is opened on each of the two fixing plates 805, and the two oblique holes 806 are in opposite directions.

[0027] In this utility model, each slider 7 is slidably fitted with a T-shaped pull rod 702 at the top of the rectangular hole 701. Both sliders 7 have square holes adapted to the T-shaped pull rods 702. Both sides of the bottom of the two T-shaped pull rods 702 are fixedly connected with protruding rods 703. Each protruding rod 703 is slidably connected in adjacent oblique holes 806. The top of the T-shaped pull rods 702 has a horizontal hole 704.

[0028] In this utility model, a driving mechanism is provided at the top of the two sliders 7 near the horizontal hole 704. The driving mechanism includes an N-shaped plate 9 fixedly connected to the top of the slider 7 near the horizontal hole 704. A rotating rod 902 is rotatably sleeved near the bottom of the N-shaped plate 9. The two ends of the rotating rod 902 are fixedly connected to the same U-shaped push rod 901. A limiting wheel 903 is fixedly sleeved in the middle of the rotating rod 902, and multiple slots are opened on the circumferential surface of the limiting wheel 903. The two ends of the bottom of the U-shaped push rod 901 are fixedly connected to the same driving rod 904, and the driving rod 904 is slidably connected in the adjacent horizontal holes 704.

[0029] In this utility model, the driving mechanism also includes a T-shaped rod 905 that is slidably sleeved at the top center of the N-shaped plate 9. The top of the N-shaped plate 9 has a square hole that matches the T-shaped rod 905. The bottom of the T-shaped rod 905 is fixedly connected to a T-shaped plate 907, and the bottom of the T-shaped plate 907 matches the slot of the limiting wheel 903. A spring 906 is sleeved on the T-shaped rod 905 at the bottom of the N-shaped plate 9. Through the cooperation between the T-shaped plate 907 and the limiting wheel 903, the U-shaped push rod 901 will not loosen without human operation, thus improving the stability of the cutter 604.

[0030] In this utility model, strip grooves are provided on both sides of the inner wall of the rectangular groove 601. A rubber pad 602 is fixedly connected in each strip groove, and the rubber pad 602 is adapted to the anti-slip strip 804. Through the cooperation of the rubber pad 602 and the locking mechanism 8, the slider 7 with the cutter 604 stays in a stable position and will not slide.

[0031] In this invention, cutters 604 are slidably sleeved at both ends of the main shaft 6. Each cutter 604 has a fixing hole at its top, and a fastening bolt 605 is provided in each fixing hole. Each fastening bolt 605 is screwed to the adjacent slider 7. Each slider 7 has a threaded hole at its top that matches the fastening bolt 605. An anti-loosening washer is provided between the fastening bolt 605 and the cutter 604 to improve the fixation of the cutter 604. At the same time, when the cutter 604 needs to be replaced, it can be disassembled and replaced by loosening the fastening bolt 605.

[0032] Working principle: When using this device, if the position of the cutter 604 needs to be adjusted, there is no need to tighten or loosen the bolts. Pull the top of the T-shaped rod 905 to separate the T-shaped plate 907 from the limiting wheel 903. Then, rotate the end of the U-shaped push rod 901 away from the drive rod 904 upwards. Through the cooperation of the drive rod 904 and the horizontal hole 704, the T-shaped pull rod 702 descends. With the cooperation of the convex rod 703 and the inclined hole 806, the two extrusion blocks 803 move closer to each other, causing the anti-slip strip 804 to separate from the rubber pad 602. At this time, the slider 7 and the cutter 604 can be moved along... The U-shaped push rod 702 slides along the rectangular groove 601. When it reaches the desired position, the T-shaped rod 905 is pulled, and the top of the U-shaped push rod 901 is pressed down. This causes the T-shaped pull rod 702 to rise along with the protruding rod 703. The protruding rod 703 drives the inclined hole 806 of the locking mechanism 8, causing the two pressing blocks 803 to separate from each other. This causes the anti-slip strip 804 to press against the rubber pad 602, fixing the slider 7 and preventing it from sliding. With the cooperation of the T-shaped plate 907 and the limiting wheel 903, the U-shaped push rod 901 is kept in a stable state, ensuring that the cutter 604 is in a stable state when the device is working.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
