Description

Technical Field

[0001] This utility model relates to the technical field of composite film production equipment, and in particular to a slicing device for high-transparency and fold-resistant composite films. Background Technology

[0002] High-transparency, fold-resistant composite film is a novel thin-film material combining high transparency and excellent fold resistance, widely used in packaging, electronics, and medical fields. It employs a multi-layer composite process, combining a high-transparency substrate with a fold-resistant reinforcing layer to balance visual appeal and mechanical strength requirements. In fields such as electronic display protective films, food and pharmaceutical packaging, and flexible circuit boards, high-transparency, fold-resistant composite film effectively improves product protection and lifespan while meeting environmental recycling requirements, representing an important direction for the upgrading of modern industrial materials.

[0003] For example, Chinese Patent No. CN202320509867.4 discloses a composite film cutting machine, which includes a frame and a conveyor belt mounted on the frame. The conveyor belt is used to drive the composite film to move. A top plate is provided on the top of the frame. A sliding frame is installed on the frame. Gear teeth are evenly distributed on both sides of the inner circle of the sliding frame. A toothed gear is installed inside the sliding frame. When the toothed gear rotates one revolution, it drives the sliding frame to move up and down on the frame once. A connecting column is connected to the bottom of the sliding frame. A connecting plate is connected to the bottom of the connecting column. The bottom of the connecting plate is elastic. The device is equipped with a cutter. A conveyor belt moves the composite film, while a toothed gear rotates, driving a sliding frame to move up and down. Each rotation of the toothed gear causes the sliding frame to reciprocate once. When the sliding frame reaches its lowest point, the cutter also reaches its lowest point, cutting the composite film on the conveyor belt to the required size. This improves cutting accuracy and work efficiency. However, in actual use, due to prolonged continuous cutting, the cutter generates heat, which can cause the composite film to stick together during cutting, affecting subsequent cutting results. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a slicing device for high-transparency, fold-resistant composite films, comprising a conveyor belt, a cutting device fixedly installed above the conveyor belt, a first movable groove inside the cutting device, a cutting device movably installed inside the first movable groove, a second movable groove on the side of the cutting device, a pressing plate movably installed inside the second movable groove, a slot between the second movable groove and the first movable groove, a third movable groove on the side of the pressing plate near the cutting device, a fixed post fixedly installed inside the third movable groove, a spring surrounding the fixed post, a first connecting block movably sleeved around the fixed post, the first connecting block being located at one end of the spring, and one end of the first connecting block being fixedly connected to the side of the cutting device, a limiting groove inside the second movable groove, a second connecting block movably installed inside the limiting groove, and the second connecting block being fixedly connected to the side of the pressing plate.

[0005] As an improvement to the above technical solution, several movable slots are provided on both sides above the conveyor belt. Movable blocks are movably installed inside the movable slots. Sliding grooves are provided on both sides inside the movable slots. Sliding blocks are movably arranged inside the sliding grooves, and the sliding blocks are fixedly connected to the side of the movable blocks. A stop block is fixedly installed at the higher end of the movable block, and a bolt is movably arranged on the surface of the lower end of the movable block.

[0006] As an improvement to the above technical solution, a rubber pad is fixedly installed at the lower end of the pressing plate.

[0007] As an improvement to the above technical solution, the length of the movable groove is greater than the length of the groove opening.

[0008] As an improvement to the above technical solution, the initial height of the pressing plate is lower than that of the cutter.

[0009] The beneficial effects of this utility model are as follows: A second movable groove is opened on the side of the cutter, and a pressing plate is movably installed inside. A groove is opened between the second movable groove and the first movable groove. A third movable groove is opened on the side of the pressing plate near the cutter.

A limiting groove and the second connecting block are fixedly connected to the side of the pressing plate on the inner side of the second movable groove. This allows the pressing plate to press down on the composite film in advance when the cutter cuts it, preventing displacement during the cutting process and ensuring cutting accuracy. It also prevents the cutter from sticking to the composite film, thus preventing it from affecting subsequent cutting. The spring provides the pressing plate with a certain elastic buffering effect, avoiding damage to the composite film due to excessive pressure. The pressing plate can move flexibly with the movement of the cutter, ensuring the stability and reliability of the entire cutting process and improving the quality and efficiency of the slices.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a slicing device for a high-transparency, fold-resistant composite film, including a conveyor belt 10, a cutting device 11 fixedly installed above the conveyor belt 10, a moving groove 12 inside the cutting device 11, a cutting blade 13 movably installed inside the moving groove 12, a moving groove 20 on the side of the cutting blade 13, a pressing plate 21 movably installed inside the moving groove 20, a slot 22 between the moving groove 20 and the moving groove 12, a moving groove 3 23 on the side of the pressing plate 21 near the cutting blade 13, a fixing post 24 fixedly installed inside the moving groove 3 23, a spring 25 around the fixing post 24, a connecting block 26 movably sleeved around the fixing post 24, the connecting block 26 being located at one end of the spring 25, and one end of the connecting block 26 being fixedly connected to the side of the cutting blade 13, a limiting groove 27 inside the moving groove 20, a connecting block 28 movably installed inside the limiting groove 27, and the connecting block 28 being fixedly connected to the side of the pressing plate 21.

[0018] In this embodiment, a second movable groove 20 is opened on the side of the cutter 13, and a pressing plate 21 is movably installed inside it. A groove 22 is opened between the second movable groove 20 and the first movable groove 12. A third movable groove 23 is opened on the side of the pressing plate 21 near the cutter 13. A fixing post 24 is fixedly installed inside the pressing plate 21, and a spring 25 and a movably sleeved connecting block 26 are provided on the outside. The connecting block 26 is fixedly connected to the side of the cutter 13. A limiting groove 27 and a connecting block 28 are provided on the inner side of the second movable groove 20 and are fixedly connected to the side of the pressing plate 21. This allows the pressing plate 21 to press down on the composite film in advance when the cutter 13 cuts the composite film, preventing it from shifting during the cutting process and ensuring the accuracy of the cutting. At the same time, it can also prevent the cutter 13 from sticking to the composite film and affecting subsequent cutting. The spring 25 gives the pressing plate 21 a certain elastic buffering effect, avoiding damage to the composite film due to excessive pressure. The pressing plate 21 can move flexibly with the movement of the cutter 13, ensuring the stability and reliability of the entire cutting process and improving the quality and efficiency of the slices.

[0019] Specifically, several moving grooves 30 are provided on both sides above the conveyor belt 10. Moving blocks 31 are movably installed inside the moving grooves 30. Sliding grooves 32 are provided on both sides inside the moving grooves 30. Sliding blocks are movably installed inside the sliding grooves 32, and the sliding blocks are fixedly connected to the side of the moving blocks 31. A stop block 33 is fixedly installed at the higher end of the moving blocks 31, and a bolt 34 is movably installed on the surface of the lower end of the moving blocks 31.

[0020] In this embodiment, several movable grooves 30 are opened on both sides of the upper part of the conveyor belt 10, and movable blocks 31 are movably installed inside them. Slide grooves 32 are opened on both sides inside the movable grooves 30. Slider blocks fixed to the side of the movable blocks 31 are movably set in the slide grooves 32. A stop block 33 is fixedly installed at the higher end of the movable block 31, and a bolt 34 is movably set on the surface of the lower end. This allows the movable block 31 to move flexibly within the movable grooves 30. The cooperation between the slider and the slide groove 32 ensures the smoothness and accuracy of the movement of the movable block 31. The stop block 33 can limit the movement of the composite film on the conveyor belt 10, preventing the composite film from deviating during the conveying process and ensuring that the composite film can accurately reach the position of the cutter 13 for cutting. The bolt 34 facilitates the fixing and adjustment of the position of the movable block 31. The position of the movable block 31 can be flexibly adjusted according to the width of the composite film of different specifications, which improves the versatility and adaptability of the device and can meet the slicing requirements of composite films of various specifications.

[0021] Specifically, a rubber pad 29 is fixedly installed at the lower end of the pressing plate 21.

[0022] In this embodiment, a rubber pad 29 is fixedly installed at the lower end of the pressing plate 21, giving the rubber pad 29 good elasticity and softness. When the pressing plate 21 presses down on the composite film, the rubber pad 29 can better fit the surface of the composite film, increasing the contact area with the composite film, thereby providing more uniform pressure and further improving the fixing effect on the composite film. This effectively prevents wrinkles or displacement of the composite film during the cutting process. At the same time, the rubber pad 29 can also play a buffering role, reducing the impact force of the pressing plate 21 on the composite film, avoiding damage to the surface of the composite film due to excessive pressure, ensuring the quality and integrity of the composite film, and improving the quality of the slices.

[0023] Specifically, the length of the movable slot 23 is greater than the length of the slot 22.

[0024] In this embodiment, the length of the movable groove 23 is greater than that of the groove 22, so that the longer movable groove 23 provides more room for movement of components such as the fixed column 24, spring 25 and connecting block 26, so that the pressing plate 21 has a larger range of travel during movement, which can better adapt to composite films of different thicknesses and materials, and ensure that the pressing plate 21 can always effectively press the composite film.

[0025] Specifically, the initial height of the pressing plate 21 is lower than that of the cutter 13.

[0026] In this embodiment, by setting the initial height of the pressing plate 21 lower than that of the cutter 13, during the slicing process, when the composite film is conveyed to the position of the cutter 13, the pressing plate 21 first contacts and presses down on the composite film, and then the cutter 13 cuts the composite film. This method of pressing before cutting ensures that the composite film is firmly fixed before cutting, avoiding the displacement or wrinkling of the composite film caused by the cutter 13 contacting the composite film first, and greatly improving the cutting accuracy and quality.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
