Abstract
Description
Technical Field
[0001] This utility model relates to the field of tension slitting machine technology, and in particular to a tension slitting machine for multilayer functional films. Background Technology
[0002] In the film processing industry, multilayer functional films, due to their composite properties, are increasingly widely used in electronics, packaging, optics, and other fields. To meet production demands, tension slitting machines have become key equipment in the processing of multilayer functional films. These machines require precise control of film tension while achieving high-precision slitting to ensure that the physical properties and dimensional specifications of the films meet standards. With the industry's growing demand for diversified and refined film products, higher requirements are being placed on the performance and adaptability of tension slitting machines.
[0003] A slitting machine tension mechanism is disclosed in publication number CN206384605U. This utility model relates to the field of rubber V-belt equipment and aims to provide a slitting machine tension mechanism. The slitting machine tension mechanism includes a base, a motor reducer, a drive shaft, an auxiliary roller, an auxiliary roller bearing seat, and a polyurethane roller. The drive shaft is rotatably mounted on the base via bearings, with both ends extending out of the base. One end of the drive shaft is connected to the motor reducer, and the other end is fitted with the polyurethane roller. A front bearing cover is installed at the connection between the end of the drive shaft with the polyurethane roller and the base, and the front bearing cover has two mounting holes. The advantages of this utility model are: using a polyurethane roller with good elasticity for wire blank tube transport, and adding a rotatable auxiliary roller to the side of the polyurethane roller, which can spread the wire blank tube to both sides, greatly improving the tension of the wire blank tube and improving the cutting effect. However, because the tension roller height is fixed, it is difficult to conveniently adjust the tension when processing functional films of different specifications. Functional films of different thicknesses and materials have different tension requirements. A tension roller of fixed height cannot flexibly adapt to the optimal tension required by various functional films by changing the contact angle between the film and the roller surface, the path length, etc. Therefore, a tension slitting machine for multilayer functional films is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a tension slitting machine for multilayer functional films, which aims to improve the problem that the existing technology cannot conveniently adjust the tension of functional films of different specifications.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tension slitting machine for multilayer functional films includes a support frame, an unwinding roller and a roll are provided on the outer wall of the support frame, a slitting knife is provided on the outer wall of the support frame, a tension roller is provided inside the support frame, an adjustment component is provided on the outer wall of the tension roller, and a disassembly component is provided inside the slitting knife.

This solves the problem that existing methods of disassembling and adjusting the slitting blade require multiple tools and are not easy to disassemble, thus improving the convenience of the device.

[0033] 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. Example 1:
[0034] Reference Figures 1-3 This utility model provides an embodiment of a tension slitting machine for multilayer functional films, comprising a support frame 1. The support frame 1, as the main support structure of the equipment, is welded from high-strength steel and treated with rust prevention. It can stably bear the weight of each component of the equipment and the stress generated during operation, ensuring the stability of the equipment operation. An unwinding roller 5 is provided on the outer wall of the support frame 1. The unwinding roller 5 is used to carry the unslit multilayer functional film raw material roll. The raw material roll is quickly loaded and unloaded through an air-expanding shaft structure, which can adapt to film rolls with different inner diameters and ensure a smooth and stable unwinding process. A roll 2 and a slitting knife 3 are provided on the outer wall of the support frame 1. A tension roller 6 is provided inside the support frame 1, which is a key component for controlling the tension of the film. The outer wall of the tension roller 6 is covered with a rubber anti-slip layer, which can increase the friction with the film and prevent the film from slipping during transmission. An adjustment component is provided on the outer wall of the tension roller 6, and a disassembly component is provided inside the slitting knife 3.
[0035] The adjustment assembly includes a transmission block 9, the outer wall of which is set at one end of the tension roller 6. A limiting groove 4 is opened inside the support frame 1 to limit the movement direction of the tension roller 6 and ensure its stable sliding in the vertical direction. The outer wall of the tension roller 6 is slidably connected inside the limiting groove 4. A fixed outer shell 7 is fixedly connected to the outer wall of the support frame 1. A transmission belt 8 is rotatably connected inside the fixed outer shell 7. The transmission block 9 is fixedly connected to the outer wall of the transmission belt 8. The rotation of the transmission belt 8, combined with the guiding effect of the limiting groove 4 on the tension roller 6, drives the transmission block 9 and the tension roller 6 to slide inside the limiting groove 4, thereby achieving precise adjustment of the height of the tension roller 6 to meet the tension requirements of different specifications of functional films.
[0036] Specifically, when slitting multi-layer functional films, operators can activate the transmission belt 8 when dealing with functional films of different thicknesses and materials. Driven by a motor, the transmission belt 8 rotates at a stable speed, using strong friction to drive the transmission block 9 to achieve precise lifting and lowering along a predetermined track. The transmission block 9 is closely connected to the tension roller 6. Driven by the transmission block 9, the tension roller 6 can slide smoothly and steadily within the limiting groove 4. By adjusting the height of the tension roller 6, the wrap angle and contact path between the functional film and the tension roller 6 can be changed, thereby flexibly adjusting the tensile tension to perfectly match the specifications of the current functional film. Whether it is an ultra-thin optical film or a thicker packaging film, just the right tension control can be achieved. After adjustment, the functional film will enter the next process, where it will be cut by a sharp and precise slitting blade 3, cutting the entire roll of functional film into the required width. Finally, the cut functional film is wound up under the traction of the roll 2. The entire process is completed in one go, significantly improving the equipment's processing capacity and production efficiency for functional films of different specifications, and greatly expanding the application range of the equipment. Example 2:
[0037] Reference Figure 1 , Figures 4-6 The assembly and disassembly components include a retaining ball 19, which, as a key positioning component, is made of high-hardness stainless steel with a polished surface, exhibiting good wear resistance and smoothness. It is positioned inside the slitting blade 3 and engages with the retaining groove 12 to position and fix the slitting blade 3. The retaining ball 19 is located inside the slitting blade 3. A transmission roller 10 is installed inside the support frame 1, with a moving groove 11 and a retaining groove 12 inside the transmission roller 10. The outer wall of the retaining ball 19 is slidably connected to the retaining groove 12. A connecting block 13 is fixedly connected to the outer wall of the slitting blade 3. The connecting block 13 contains... The connecting housing 14 is fixedly connected to the connecting housing 14. A pull rod 15 is slidably connected inside the connecting housing 14. The pull rod 15 is made of stainless steel and the surface is treated with anti-rust. A limit post 21 is fixedly connected to the bottom of the pull rod 15. A conical post 17 is fixedly connected to the bottom of the limit post 21. A limit post 16 is fixedly connected to the bottom of the conical post 17. A sliding groove 18 is opened inside the connecting housing 14. The outer wall of the retaining ball 19 is slidably connected to the inside of the sliding groove 18. A spring 20 is sleeved on the outer wall of the pull rod 15. The top of the spring 20 is fixedly connected to the inner wall of the connecting housing 14, and the bottom of the spring 20 is fixedly connected to the top of the limit post 21.
[0038] Specifically, in the slitting operation of multi-layer functional films, slitting is often required at different locations according to production needs. The operator pulls the lever 15, which acts like a start button for a precision mechanical system, causing the second limiting post 21 to slide smoothly along a predetermined track inside the connecting housing 14. During this process, the spring 20 is compressed, accumulating elastic potential energy. As the second limiting post 21 moves, the conical post 17 connected to it also moves. Utilizing the unique inclined structure of the conical post 17, it cleverly pushes the first limiting post 16 to slide, thereby causing the retaining ball 19 to slide flexibly within the groove 18. At this time, the connecting block 13 is freed from the restraint of the retaining ball 19 and can slide freely on the outer wall of the transmission roller 10. After the operator moves the connecting block 13 to a suitable position that meets the slitting requirements, he releases the pull rod 15. The compressed spring 20 instantly releases its elastic potential energy and rebounds, causing the limit post 21 to return to its original position. This pushes out the locking ball 19 and precisely engages it inside the locking groove 12, firmly fixing the connecting block 13 in place. This allows the slitting blade 3 to be quickly adjusted to the required slitting position, efficiently completing slitting tasks at different positions.
[0039] Working principle: When slitting multi-layer functional films, the transmission belt 8 can be started, which drives the transmission block 9 to rise and fall. Then, the transmission block 9 drives the tension roller 6 to slide inside the limiting groove 4, thereby adjusting the tensile tension and improving the performance of functional films of different specifications. Finally, the films are slit by the slitting knife 3 and wound up by the roll 2, improving the applicability of the device.
[0040] Additionally, when cutting at different positions, the pull rod 15 can be pulled, causing the second limiting post 21 to slide inside the connecting housing 14, compressing the spring 20. Then, the second limiting post 21 drives the conical post 17 to move, and the conical post 17 drives the first limiting post 16 to slide, allowing the ball 19 to slide inside the groove 18, and the connecting block 13 to slide on the outer wall of the transmission roller 10. Once the ball 19 is in the appropriate position, the pull rod 15 is released, and the spring 20 rebounds, causing the second limiting post 21 to return to its original position, pushing the ball 19 out and engaging it inside the slot 12, thus fixing the connecting block 13 and cutting at different positions.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
