Description

Technical Field

[0001] This utility model relates to the technical field of composite film processing equipment, and in particular to a composite film cutting device that facilitates preventing film shrinkage and rewinding. Background Technology

[0002] Composite membranes are thin films made by combining two or more different materials through a composite process. Their basic structure usually includes a support layer and one or more functional layers. This structure gives composite membranes a variety of superior properties. However, composite membranes need to be cut and processed according to the actual situation before use.

[0003] Composite films, as a material with many excellent properties, have been widely used in food packaging, electronic materials, medical supplies, and other fields. Cutting is an essential process in the production and processing of composite films. However, existing composite film cutting devices have many problems in practical applications. Composite films are usually made of multiple materials. During the cutting process, due to the release of internal stress and the influence of environmental factors such as temperature and humidity, the film is prone to shrinkage and rewinding. For example, when using traditional cutting devices to cut composite films, the edges of the cut film often shrink and rewind, resulting in inaccurate film dimensions that cannot meet packaging requirements. This not only wastes a lot of raw materials but also increases production costs. To address these issues, we propose a composite film cutting device that prevents film shrinkage and rewinding. Utility Model Content

[0004] The purpose of this invention is to provide a composite film cutting device that facilitates the prevention of film shrinkage and rewinding, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite film cutting device for preventing film shrinkage and rewinding includes a cutting table, a square cylinder fixedly connected to the back of the cutting table, a driving component installed on the inner wall of the square cylinder, a cutting component fixedly connected to the front of the square cylinder, two transmission rods mounted on the driving component above the cutting table, a square plate fixedly connected to the outer surface of each transmission rod, a U-shaped pressure frame fixedly connected to the outer surface of each of the two square plates, and the cutting component located between the two U-shaped pressure frames, with two protrusions fixedly connected to the outer surface of each U-shaped pressure frame.

[0007] In a further embodiment, a first electric cylinder is fixedly installed on the inner wall of the square cylinder, and a square horizontal plate is fixedly connected to the output end of the first electric cylinder. Both the left and right ends of the square horizontal plate extend to the outside of the square cylinder, and the outer surface of each transmission rod is fixedly connected to the outer surface of the square horizontal plate.

[0008] In a further embodiment, a bottom frame is fixedly connected to the bottom surface of the cutting table. Two sliding rods and an electric push rod are fixedly connected to the inner wall of the bottom frame. A movable plate is fixedly connected to the output end of the electric push rod. An I-beam is slidably connected to the outer surfaces of the two sliding rods. Two sets of connecting rods are fixedly connected to the outer surface of the I-beam. A pressure plate is fixedly connected to the top end of each set of connecting rods. Two round rods are fixedly connected to the upper surface of the movable plate. The top end of each round rod penetrates the bottom frame and is fixedly connected to the bottom surface of the I-beam.

[0009] In a further embodiment, the cutting component includes a sliding cylinder fixedly installed on the outer surface of the square cylinder. A sliding rod is slidably connected inside the sliding cylinder. An L-shaped connecting rod is fixedly connected to the bottom surface of the sliding rod. A square frame is fixedly connected to one end of the L-shaped connecting rod. A second electric cylinder is fixedly connected to the inner wall of the square frame. A cutting blade is fixedly connected to the output end of the second electric cylinder. A third electric cylinder is fixedly connected to the upper surface of the sliding cylinder. A block is fixedly connected to the output end of the third electric cylinder, and the outer surface of the block is fixedly connected to the outer surface of the sliding rod.

[0010] In a further embodiment, the bottom surface of the cutting table is fixedly connected to two support bases, and the outer surface of each support base is provided with multiple mounting holes.

[0011] In a further embodiment, the upper surface of the cutting table is provided with a cutting groove, and the cutting groove is located directly below the cutting blade.

[0012] In a further embodiment, the outer surface of the square tube has two square openings, and the square horizontal plate is slidably connected to the square openings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses a drive unit to move a transmission rod, a square plate, and a U-shaped pressure frame. Before cutting, it presses and fixes the composite film near the cutting position. The protrusions on the U-shaped pressure frame increase the friction with the film, further preventing the film from shrinking and curling back during the cutting process due to factors such as the release of internal stress. This ensures accurate film dimensions after cutting, reduces raw material waste and production costs, and ensures that the U-shaped pressure frame can tightly press the film during the cutting process, making the edges of the cut film flat and the dimensions meeting packaging requirements.

[0015] This device achieves precise cutting through the design of the cutting components. The structure, including the support cylinder, sliding rod, and third electric cylinder, allows for flexible adjustment of the cutting position. The second electric cylinder controls the cutting action of the cutting blade, which, together with the blade groove on the cutting table, improves cutting efficiency and quality.

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.

[0025] Please see Figures 1-5 In this utility model, a composite film cutting device for preventing film shrinkage and rewinding includes a cutting table 1. A square cylinder 2 is fixedly connected to the back of the cutting table 1. A driving component 7 is installed on the inner wall of the square cylinder 2. A cutting component 3 is fixedly connected to the front of the square cylinder 2. Two transmission rods 8, which are installed on the driving component 7, are arranged above the cutting table 1. A square plate 9 is fixedly connected to the outer surface of each transmission rod 8. A U-shaped pressure frame 10 is fixedly connected to the outer surface of each of the two square plates 9. The cutting component 3 is located between the two U-shaped pressure frames 10. Two protrusions 11 are fixedly connected to the outer surface of each U-shaped pressure frame 10. The driving component 7 drives the U-shaped pressure frame 10 to move through the transmission rods 8, thereby pressing the film and constructing a basic structure to prevent the film from shrinking and rewinding and to cut it. The cutting component 3 is located between the two U-shaped pressure frames 10, which facilitates the cutting of the film. With the help of the protrusions 11, it effectively prevents the film from shrinking and rewinding.

[0026] A first electric cylinder 701 is fixedly installed on the inner wall of the square cylinder 2. A square horizontal plate 702 is fixedly connected to the output end of the first electric cylinder 701. Both ends of the square horizontal plate 702 extend to the outside of the square cylinder 2. The outer surface of each transmission rod 8 is fixedly connected to the outer surface of the square horizontal plate 702. By operating the first electric cylinder 701 and moving the transmission rod 8 through the square horizontal plate 702, the position of the U-shaped pressure frame 10 is adjusted, which is convenient to adapt to composite diaphragms of different sizes. The power output is stable, ensuring the pressing effect on the diaphragm. When the first electric cylinder 701 is started, the square horizontal plate 702 moves the transmission rod 8 and the U-shaped pressure frame 10 to the appropriate position to press and fix the diaphragm.

[0027] A base frame 4 is fixedly connected to the bottom surface of the cutting table 1. Two sliding rods 16 and an electric push rod 13 are fixedly connected to the inner wall of the base frame 4. A moving plate 14 is fixedly connected to the output end of the electric push rod 13. An I-beam 17 is slidably connected to the outer surfaces of the two sliding rods 16. Two sets of connecting rods 18 are fixedly connected to the outer surface of the I-beam 17. A pressure plate 19 is fixedly connected to the top of each set of connecting rods 18. Two round rods 15 are fixedly connected to the upper surface of the moving plate 14. The top of each round rod 15 penetrates the base frame 4 and connects to the bottom frame 4. The bottom surface of the I-beam frame 17 is fixedly connected to the structure consisting of the bottom frame 4, the sliding rod 16, the electric push rod 13, the moving plate 14, the I-beam frame 17, the connecting rod 18, and the pressure plate 19. This structure can support the bottom of the composite film and assist in pressing the top. The electric push rod 13 pushes the moving plate 14, causing the I-beam frame 17 and the pressure plate 19 to rise or fall, pressing the bottom of the composite film onto the cutting table 1. This ensures that the film remains stable during the cutting process. For example, when cutting thin and easily deformable composite films, this structure can effectively assist in fixing the film.

[0028] The cutting component 3 includes a sliding cylinder 301 fixedly installed on the outer surface of the square cylinder 2. A sliding rod 304 is slidably connected inside the sliding cylinder 301. An L-shaped connecting rod 305 is fixedly connected to the bottom surface of the sliding rod 304. A square frame 306 is fixedly connected to one end of the L-shaped connecting rod 305. A second electric cylinder 307 is fixedly connected to the inner wall of the square frame 306. A cutting blade 308 is fixedly connected to the output end of the second electric cylinder 307. A third electric cylinder 302 is fixedly connected to the upper surface of the sliding cylinder 301. A block 303 is fixedly connected to the output end of the third electric cylinder 302, and the outer surface of the block 303 is flush with the sliding rod 304. The outer surface of the cutting table 1 is fixedly connected. The sliding cylinder 301, sliding rod 304, and third electric cylinder 302 in the cutting component 3 can flexibly adjust the cutting position. The second electric cylinder 307 controls the cutting depth of the cutting blade 308, which can meet the cutting requirements of different composite films and improve cutting accuracy and quality. The bottom surface of the cutting table 1 is fixedly connected to two support seats 5. Each support seat 5 has multiple mounting holes 6 on its outer surface. The support seats 5 provide stable support for the cutting table 1. The mounting holes 6 make it easy to fix the cutting device on the worktable, ensuring that the device will not shake during the cutting process, which is conducive to improving cutting accuracy and ensuring the stability of the cutting table 1.

[0029] The upper surface of the cutting table 1 is provided with a cutting groove 20, which is located directly below the cutting blade 308. The cutting groove 20 cooperates with the cutting blade 308 to provide cutting space for the cutting blade 308 during cutting, preventing the cutting blade 308 from damaging the cutting table 1. At the same time, it can make the edge of the cut film more neat and improve the cutting quality. The outer surface of the square cylinder 2 is provided with two square openings 12. The square horizontal plate 702 is slidably connected to the square openings 12. The square openings 12 provide a channel for the movement of the square horizontal plate 702, ensuring the smoothness of the first electric cylinder 701 driving the transmission rod 8 and the U-shaped pressure frame 10 through the square horizontal plate 702, so as to make the device operate stably.

[0030] The working principle of this utility model is as follows:

[0031] After securing the device and connecting it to the power supply, place the composite film to be cut on the cutting table 1. Start the electric push rod 13 to move the moving plate 14 and the round rod 15, which in turn move the I-beam frame 17 and the pressure plate 19 downwards to initially press and position the composite film. Next, start the first electric cylinder 701 to move the square horizontal plate 702, which in turn moves the transmission rod 8, the square plate 9, and the U-shaped pressure frame 10, thereby enabling the two U-shaped pressure frames 10 and the protrusions 11 to align. The film is pressed again, so that the U-shaped pressure frame 10 and the protrusion 11 are located on both sides of the cutting position, which avoids shrinkage and rewinding after cutting. Then, the second electric cylinder 307 can be started to push the cutting blade 308 downward and adjust the cutting blade 308 to a suitable position. Finally, the third electric cylinder 302 is started to push the block 303 and the sliding rod 304 to slide in the support cylinder 301, which can move the sliding rod 304, the L-shaped connecting rod 305 and the cutting blade 308 back and forth to cut the fixed composite film.
