Description

Technical Field

[0001] The present invention relates to the technical field of optical film processing, and more specifically, to a cutting device for an optical film and a method for using the same. Background Art

[0002] An optical film is a thin film material with specific optical properties and is widely used in various fields. It can be a single-layer or multi-layer structure and can be designed into different types of films according to application requirements, such as an antireflection film, a reflection film, a filter film, etc. For the cutting of an optical film, it is necessary to comprehensively consider its material properties, precision requirements, size, and protection of optical performance. Different optical film substrates may have different hardness, brittleness, or toughness, which directly affects the choice of the usage method. For example, for very thick or multi-layer optical films composed of different materials, traditional mechanical cutting may cause problems such as edge burrs, cracks, or delamination; while laser cutting is difficult to achieve uniform energy distribution due to thickness problems, which may result in incomplete cutting or material damage. In this case, the water jet usage method becomes the best choice.

[0003] Water jet cutting is a technology that uses a high-speed water flow as a cutting tool. It can cut without generating heat, not only providing enough energy to penetrate thicker materials but also not applying excessive thermal stress to the material, thus ensuring the quality and precision of cutting. However, when dealing with some special materials, such as composite optical films on automotive glass or high-strength protective films for industrial use, pure water jets may not be sufficient to provide enough cutting force. To improve cutting efficiency and quality, it is usually necessary to add an appropriate amount of abrasive to the high-speed water flow.

[0004] Although adding abrasive can significantly enhance the cutting ability, different materials of optical films have different requirements for the abrasive particle size. For example, when facing thicker or harder materials, it is more appropriate to choose a slightly larger particle size; while for thinner or more brittle materials, finer abrasives should be used to reduce the impact on the material surface. Therefore, to ensure the best cutting effect, it is necessary to replace the corresponding abrasive particle size according to the specific material during the operation process. However, this process is rather cumbersome, difficult to quickly adapt to the diverse needs in actual production, and increases the operation complexity and time cost. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a cutting device for an optical film and a method for using the same, aiming to solve the above technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

And the outer circular surface of the gear sleeve seat is in threaded connection with the receiving sleeve.

[0010] As a further scheme of the present invention: The first fixing ring and the second fixing ring together form a first activity groove for the movement of the first support plate. The inner walls of the first fixing ring and the second fixing ring are both fixedly connected with filter meshes for filtering impurities in the abrasive.

[0011] As a further scheme of the present invention: The jet mixing mechanism includes a buffer pipe fixedly communicated with the bottom of the circulation pipe. The outer circular surface of the circulation pipe is surrounded by a second support plate, and the second support plate is movably connected in the second activity groove. The buffer pipe penetrates through the partition board and the sealed tank and is fixedly connected with a nozzle. A conveying pipe fixedly communicated with the buffer pipe is arranged directly below the material discharging port. A fixed sleeve seat is fixedly connected to the outer circular surface of the buffer pipe.

[0012] As a further scheme of the present invention: A rotating rod is arranged inside the buffer pipe. At both ends of the rotating rod, limit sleeve seats fixedly connected with the inner wall of the buffer pipe are provided. An impeller for further mixing the abrasive and water is fixedly connected to the outer circular surface of the rotating rod.

[0013] As a further solution of the present invention: the inner wall of the gear blade disc is provided with blades that form an inclination angle of 45 degrees with the horizontal plane of the support seat, and the blades are used to drive the gear blade disc to rotate by the impact of water flow. The outer circular surface of the gear blade disc is in the shape of a gear, and the inner wall of the gear sleeve seat is provided with a tooth disc that meshes with the gear blade disc. The bottom end of the outer circular surface of the gear sleeve seat is provided with a threaded ring that is threadedly connected to the support pipe for subsequent disassembly and cleaning.

[0014] As a further solution of the present invention: the grinding mechanism includes a fixed disc arranged at the bottom of the support pipe. The fixed disc and the support pipe are fixedly connected with a first connecting rod. Both sides of the bottom of the fixed disc are fixedly connected with blocking blocks. The bottom of the fixed disc is fixedly connected with an L-shaped support rod. The outer surface of the L-shaped support rod is rotatably connected with a first grinding roller. The bottom of the fixed disc is fixedly connected with a second connecting rod. The fixed disc is fixedly connected with a first scraping plate through the second connecting rod.

[0015] As a further solution of the present invention: the outer diameter of the blocking block is larger than the outer diameter of the feeding port. The outer surfaces of the first scraping plate and the first grinding roller are both attached to the upper surface of the partition plate.

[0016] As a further solution of the present invention: a cleaning mechanism is arranged on the outer circular surface of the support pipe. The cleaning mechanism includes an annular pipe arranged on one side of the outer circular surface of the support pipe. The annular pipe is fixedly connected with a support column on the side close to the support pipe. The annular pipe is rotatably connected with a second grinding roller on the side close to the sealed tank.

[0017] As a further solution of the present invention: the cleaning mechanism further includes a vertical plate arranged on the other side of the outer circular surface of the support pipe. Both ends of the inner side of the vertical plate are provided with connecting plates fixedly connected with the support pipe. Cleaning brushes for cleaning the filter screen are fixedly connected to both ends of the vertical plate. A second scraping plate for cleaning the dirt on the inner wall of the sealed tank is fixedly connected to the outer side of the vertical plate.

[0018] A usage method of a cutting device for an optical film, the usage method includes the following steps:

[0019] S1: Connect the water inlet pipe to an external high-pressure water supply device, and add the required abrasive into the sealed tank through the feeding pipe. At this time, start the externally connected high-pressure water supply device, so that the high-pressure water flow flows into the sealed tank from the water inlet pipe and flows downward through the circulation pipe;

[0020] S2: The high-pressure water flow impacts the blades with a 45-degree inclination angle set on the inner wall of the gear disk, generating sufficient torque to drive the rotation of the gear disk. As a result, the engaged gear sleeve seat drives the gear sleeve seat to rotate synchronously, and then the support pipe rotates. With the rotation of the support pipe, the abrasive on the partition is milled by the first milling roller to ensure that all abrasives can be fully milled. The first scraper scrapes the milled abrasives into the feed opening to ensure that the abrasives smoothly enter the subsequent mixing and spraying processes.

[0021] S3: The abrasives are fed into the sealed tank through the feed pipe and fall into the buffer pipe through the feed opening on the partition. Under the action of the water flow impact force, the rotating rod and the impeller rotate, further enhancing the turbulence effect of the water flow and enabling the abrasives to be strongly mixed with the water.

[0022] S4: The mixed abrasives and the high-speed water flow are ejected through the nozzle at the bottom of the buffer pipe, and the nozzle is used to efficiently cut the optical film.

[0023] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0024] (1) In this solution, a support mechanism, a driving mechanism, and a milling mechanism are provided. During use, the milling mechanism located at the bottom of the support pipe can adjust its movement intensity according to the change of the water flow pressure. When the water flow enters the sealed tank, its flow rate directly affects the rotation speed of the gear disk, and then changes the working intensity of the milling mechanism. By controlling the water pressure of the external high-pressure water supply device, the milling degree of the abrasives can be flexibly adjusted to meet the cutting requirements of optical films with different thicknesses or materials. After being appropriately milled, the abrasives are mixed with the high-speed water flow and ejected through the nozzle to achieve efficient cutting of the optical film. The whole process does not require frequent replacement of abrasives, greatly improving the operation convenience and work efficiency.

[0025] (2) By setting up a jet mixing mechanism, when the high-pressure water flow enters the sealed tank from the water inlet pipe and flows downward through the circulation pipe, at this time, using the impact force of the water flow, the impeller rotates. The rotation of the impeller not only realizes the efficient mixing of the abrasives and the water, but also significantly improves the quality and efficiency of the optical film cutting. At the same time, during the process of jet cutting with the mixed high-speed water flow, the reasonable layout of the conveying pipe and the buffer pipe and the continuous stirring effect of the impeller effectively prevent the accumulation of abrasives and pipeline blockage, ensuring the long-term stable operation of the system.

[0026] (3) By providing a grinding mechanism, during the rotation of the support tube, the fixed disk is synchronously rotated by means of the first connecting rod, and the first grinding roller is driven by the L-shaped support rod to rotate on the partition plate, so that the first grinding roller grinds the abrasive on the partition plate. The first scraper can scrape the ground abrasive into the material discharge port, ensuring that the abrasive smoothly enters the subsequent mixing and spraying processes. And during the rotation of the fixed disk, since the outer diameter of the blocking block is larger than the outer diameter of the material discharge port, it can prevent the abrasive from directly falling into the buffer tube through the material discharge port without being processed, ensuring that all the abrasive can undergo grinding treatment.

However, this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation mode

[0046] The following will describe in detail an optical film cutting device and its usage method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0047] As Figures 1 to 7 shown, the embodiments of the present invention provide an optical film cutting device and its usage method, including a sealed tank 1. The top of the sealed tank 1 is threadedly connected with a sealed cover 2. The middle of the top of the sealed cover 2 is fixedly communicated with a water inlet pipe 3. One side of the top of the sealed cover 2 is provided with a feed pipe 4 for delivering abrasive. The middle of the inside of the sealed tank 1 is provided with a circulation pipe 7. The inner wall of the sealed tank 1 is provided with a support mechanism 5 for supporting the circulation pipe 7. The bottom end of the inner wall of the sealed tank 1 is fixedly connected with a partition plate 6. Both sides of the inside of the partition plate 6 are provided with material discharge openings 61. The bottom of the circulation pipe 7 is provided with a jet mixing mechanism 8 for jetting high-pressure water flow containing abrasive. The top of the circulation pipe 7 is provided with a driving mechanism 11;

[0048] Among them, the support mechanism 5 includes a support pipe 54 arranged inside the sealed tank 1. At both ends of the outer cylindrical surface of the support pipe 54, there are a first fixing ring 51 and a second fixing ring 52 fixedly connected to the inner wall of the sealed tank 1. At both ends of the outer cylindrical surface of the support pipe 54, there are fixedly connected first support plates 55 for support. At the top of the support pipe 54, there is fixedly connected a receiving sleeve 56. At the bottom of the support pipe 54, there is a grinding mechanism 12 for abrasive processing.

[0049] Among them, the driving mechanism 11 includes a support seat 111 fixedly connected to the middle of the inner top wall of the flow pipe 7. Inside the support seat 111, there is a rotatably connected support rod 112. On the outer cylindrical surface of the support rod 112, there is a rotatably connected gear blade disc 113. On the outer cylindrical surface of the gear blade disc 113, there is a meshing connection with a gear sleeve seat 114. And the outer cylindrical surface of the gear sleeve seat 114 is in threaded connection with the receiving sleeve 56.

[0050] As Figure 1 , Figure 2 shown, the first fixing ring 51 and the second fixing ring 52 together form a first moving groove for the movement of the first support plate 55. The inner walls of the first fixing ring 51 and the second fixing ring 52 are both fixedly connected with filter meshes 53 for filtering impurities in the abrasive. At the inner bottom of the support pipe 54, there are fixedly connected two third fixing rings 57, and the two third fixing rings 57 together form a second moving groove.

[0051] In order to solve the problem that the existing optical film cutting equipment needs to change the corresponding abrasive particle size according to the specific material during operation, which makes the operation process cumbersome and takes a long time, and it is difficult to quickly adapt to the diversified needs in actual production, increasing the complexity of operation and time cost, the above technical solution is now adopted to solve the problem. The above technical solution is mainly composed of a support mechanism 5, a driving mechanism 11, and a grinding mechanism 12. When in use, the water inlet pipe 3 is connected to the external high-pressure water supply equipment, and the required abrasive is added to the sealed tank 1 through the feeding pipe 4. The top of the sealed tank 1 is threadedly connected with a sealing cover 2 to ensure the sealing and stability of the entire system. Start the external high-pressure water supply equipment, so that the high-pressure water flow flows from the water inlet pipe 3 into the sealed tank 1. The impact force of the water flow causes the gear blade disc 113 to rotate, driving the gear sleeve 114 to rotate synchronously. Since the gear sleeve 114 is threadedly connected to the receiving sleeve 56, the rotation of the gear sleeve 114 will cause the receiving sleeve 56 and the support pipe 54 to rotate together. This rotation mechanism ensures the smooth operation of the support tube 54, and enhances the stability of the overall structure through the movement of the first support plate 55 in the first movable groove. During the above operation, the grinding mechanism 12 located at the bottom of the support tube 54 can adjust its movement intensity according to the change of the water flow pressure. When the water flow enters the sealed tank 1, its flow rate directly affects the rotation speed of the gear blade disk 113, thereby changing the working intensity of the grinding mechanism 12. By controlling the water pressure of the external high-pressure water supply equipment, the grinding degree of the abrasive can be flexibly adjusted to meet the cutting requirements of optical films of different thicknesses or materials. After the abrasive after appropriate grinding treatment is mixed with the high-speed water flow, it is sprayed out through the jet mixing mechanism 8 to achieve efficient cutting of the optical film. The whole process does not require frequent replacement of the abrasive, which greatly improves the convenience of operation and work efficiency.

[0052] like Figure 1 , Figure 3 , Figure 4 As shown, the injection mixing mechanism 8 includes a buffer tube 81 fixedly connected to the bottom of the circulation tube 7, a second support plate 10 is arranged around the outer circumferential surface of the circulation tube 7, and the second support plate 10 is movably connected to the second movable groove, the buffer tube 81 passes through the partition 6, the sealing tank 1 is fixedly connected with a nozzle 82, a delivery pipe 83 fixedly connected to the buffer tube 81 is arranged directly below the discharge port 61, and the outer circumferential surface of the buffer tube 81 is fixedly connected to a fixed sleeve 9.

[0053] like Figure 4 As shown, a rotating rod 84 is disposed inside the buffer tube 81 , and both ends of the rotating rod 84 are provided with limiting sleeves 86 fixedly connected to the inner wall of the buffer tube 81 , and the outer circumferential surface of the rotating rod 84 is fixedly connected to an impeller 85 for further mixing the abrasive and water.

[0054] When high-pressure water flow enters the sealed tank 1 from the water inlet pipe 3 and flows downward through the circulation pipe 7. At this time, the abrasive is fed into the sealed tank 1 through the feeding pipe 4 and falls into the buffer pipe 81 through the material discharge port 61 on the partition plate 6. Under the action of the water flow impact force, the abrasive and water start to be preliminarily mixed. Since a rotating rod 84 is arranged inside the buffer pipe 81, and its two ends are fixedly connected to the inner wall of the buffer pipe 81 through the limit sleeve seats 86, ensuring the stability and rotational freedom of the rotating rod 84. When the high-pressure water flow passes through the buffer pipe 81, the kinetic energy of the water flow drives the rotating rod 84 and the impeller 85 to rotate. The rotation of the impeller 85 not only enhances the turbulent effect of the water flow but also further strongly mixes the abrasive and water, ensuring their uniform distribution, improving the mixing efficiency and quality. The mixed abrasive and high-speed water flow are ejected through the nozzle 82 at the bottom of the buffer pipe 81. By setting the nozzle 82, the concentration and high pressure of the water flow are ensured, thus realizing the efficient cutting of the optical film. At the same time, the conveying pipe 83 directly below the material discharge port 61 is fixedly communicated with the buffer pipe 81, ensuring that the abrasive can smoothly enter the buffer pipe 81 for mixing and avoiding the occurrence of blockage. And during the above operation process, since the outer circumferential surface of the circulation pipe 7 is surrounded by the second support plate 10, and this support plate is movably connected to the second movable groove formed by the third fixing ring 57, thus ensuring the stability of the circulation pipe 7 and its related components during the working process. And the fixing sleeve seat 9 is used to further enhance the mechanical strength and stability of the entire jet mixing mechanism 8, preventing vibration or displacement caused by the high-pressure water flow.

[0055] As Figure 2 , Figure 3 shown, the inner wall of the gear vane disc 113 is provided with blades that form an inclined angle of 45 degrees with the horizontal plane of the support seat 111, and the blades are used for the water flow to impact and drive the gear vane disc 113 to rotate. The outer circumferential surface of the gear vane disc 113 is gear-shaped, and the inner wall of the gear sleeve seat 114 is provided with a tooth disc that meshes with the gear vane disc 113. The bottom end of the outer circumferential surface of the gear sleeve seat 114 is provided with a thread ring that is threadedly connected to the support pipe 54 for subsequent disassembly and cleaning.

[0056] As Figure 1 , Figure 5 shown, the grinding mechanism 12 includes a fixed disc 121 arranged at the bottom of the support pipe 54. The fixed disc 121 and the support pipe 54 are jointly fixedly connected with a first connecting rod 122. Both sides of the bottom of the fixed disc 121 are fixedly connected with blocking blocks 123. The bottom of the fixed disc 121 is fixedly connected with an L-shaped support rod 124. The outer surface of the L-shaped support rod 124 is rotatably connected with a first grinding roller 125. The bottom of the fixed disc 121 is fixedly connected with a second connecting rod 126. The fixed disc 121 is fixedly connected with a first scraping plate 127 through the second connecting rod 126.

[0057] As Figure 1 , Figure 5As shown, the outer diameter of the blocking block 123 is larger than that of the blanking port 61, and the outer surfaces of the first scraping plate 127 and the first grinding roller 125 are both in contact with the upper surface of the partition plate 6.

[0058] High-pressure water flow enters the sealed tank 1 from the water inlet pipe 3 and flows downward through the circulation pipe 7. The water flow impacts the blades with an inclined angle of 45 degrees arranged on the inner wall of the gear disk 113, generating sufficient torque to drive the rotation of the gear disk 113. Since the outer circular surface of the gear disk 113 is gear-shaped and meshes with the gear disk arranged on the inner wall of the gear sleeve seat 114, when the gear disk 113 rotates, it drives the gear sleeve seat 114 to rotate synchronously. At the same time, since a thread ring is arranged at the bottom end of the outer circular surface of the gear sleeve seat 114 and is threadedly connected to the support pipe 54, it ensures that the rotation of the gear sleeve seat 114 can be effectively transmitted to the support pipe 54. And this threaded connection design not only facilitates subsequent disassembly and cleaning but also enhances the stability and reliability of the system. During the rotation of the support pipe 54, the fixed disk 121 is driven to rotate synchronously by the first connecting rod 122, and the first grinding roller 125 is driven to rotate on the partition plate 6 by the L-shaped support rod 124, and the first grinding roller 125 grinds the abrasive on the partition plate 6. The first scraping plate 127 can scrape the ground abrasive into the blanking port 61 to ensure that the abrasive smoothly enters the subsequent mixing and spraying processes. During the rotation of the fixed disk 121, since the outer diameter of the blocking block 123 is larger than that of the blanking port 61, it can prevent the abrasive from directly falling into the buffer pipe 81 through the blanking port 61 without being processed, ensuring that all the abrasive can undergo grinding treatment.

[0059] As Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 shown, a cleaning mechanism 13 is arranged on the outer circular surface of the support pipe 54. The cleaning mechanism 13 includes an annular pipe 131 arranged on one side of the outer circular surface of the support pipe 54. A support column 132 is fixedly connected to the side of the annular pipe 131 close to the support pipe 54, and a second grinding roller 133 is rotatably connected to the side of the annular pipe 131 close to the sealed tank 1.

[0060] As Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 shown, the cleaning mechanism 13 further includes a vertical plate 134 arranged on the other side of the outer circular surface of the support pipe 54. Connecting plates 135 fixedly connected to the support pipe 54 are arranged at both ends inside the vertical plate 134. Cleaning brushes 137 for cleaning the filter screen 53 are fixedly connected to both ends of the vertical plate 134, and a second scraping plate 136 for cleaning the dirt on the inner wall of the sealed tank 1 is fixedly connected to the outside of the vertical plate 134.

[0061] After the abrasive enters the sealed tank 1, it is filtered through multiple layers of filter screens 53, removing other larger impurities in the abrasive, ensuring the purity of the abrasive used in the subsequent grinding and cutting processes, and improving the cutting effect. Due to the long-term use of the filter screen 53, its holes are prone to being blocked and need to be cleaned regularly to ensure its normal use. Therefore, when the high-pressure water flow drives the gear vane disc 113 to rotate, the entire support pipe 54 and its attached cleaning mechanism 13 rotate synchronously. Thus, when the support pipe 54 rotates, the annular pipe 131 rotates with it, driving the second grinding roller 133 to further grind the passing abrasive. At the same time, the support pipe 54 drives the cleaning brush 137 and the second scraper 136 to rotate simultaneously through the connecting plate 135 and the vertical plate 134, respectively. As a result, the cleaning brush 137 cleans the filter screen 53 inside the first fixing ring 51 and the second fixing ring 52. Specifically, when the support pipe 54 rotates, the cleaning brush 137 moves along with it, continuously cleaning the filter screen 53 to prevent impurities from blocking the holes of the filter screen 53 and ensuring the smooth passage of water flow and abrasive. As the support pipe 54 rotates, the second scraper 136 slides along the inner wall of the sealed tank 1, effectively removing the deposits on the inner wall, keeping the inside of the sealed tank 1 clean, and preventing dirt from affecting the normal operation of the system. Due to the continuous cleaning action of the cleaning brush 137 and the second scraper 136, the blockage of the filter screen 53 and the accumulation of dirt on the inner wall of the sealed tank 1 are prevented, the maintenance frequency is reduced, and the service life of the equipment is extended.

[0062] The usage method provided by the present invention is as follows:

[0063] S1: Connect the water inlet pipe 3 to an external high-pressure water supply device, and add the required abrasive into the sealed tank 1 through the feeding pipe 4. At this time, start the externally connected high-pressure water supply device, so that the high-pressure water flow flows into the sealed tank 1 from the water inlet pipe 3 and flows downward through the circulation pipe 7;

[0064] S2: The high-pressure water flow impacts the blades with an inclined angle of 45 degrees arranged on the inner wall of the gear vane disc 113, generating sufficient torque to drive the gear vane disc 113 to rotate. As a result, the engaged gear sleeve seat 114 drives the gear sleeve seat 114 to rotate synchronously, and then the support pipe 54 rotates. As the support pipe 54 rotates, the first grinding roller 125 is used to grind the abrasive on the partition plate 6 to ensure that all the abrasive can be fully ground. The first scraper 127 scrapes the ground abrasive into the discharge opening 61 to ensure that the abrasive smoothly enters the subsequent mixing and spraying processes;

[0065] S3: The abrasive is fed into the sealed tank 1 through the feeding pipe 4 and falls into the buffer pipe 81 through the discharge opening 61 on the partition plate 6. Under the action of the water flow impact force, the driving rod 84 and the impeller 85 rotate, further enhancing the turbulent effect of the water flow, and enabling the abrasive to be strongly mixed with water;

[0066] S4: The mixed abrasive and high-speed water flow are ejected through the nozzle 82 at the bottom of the buffer pipe 81, and the optical film is efficiently cut using the nozzle 82.

[0067] When the present invention is in use, first, the water inlet pipe 3 is connected to an external high-pressure water supply device, and the required abrasive is added into the sealed tank 1 through the feeding pipe 4. After starting the externally connected high-pressure water supply device, the high-pressure water flow flows into the sealed tank 1 from the water inlet pipe 3 and flows downward through the circulation pipe 7. The high-pressure water flow impacts the blades with an inclination angle of 45 degrees provided on the inner wall of the gear vane disc 113, generating sufficient torque to drive the rotation of the gear vane disc 113. The outer circumferential surface of the gear vane disc 113 is gear-shaped and meshes with the tooth disc provided on the inner wall of the gear sleeve seat 114, driving the gear sleeve seat 114 to rotate synchronously. Since a thread ring threadedly connected to the support pipe 54 is provided at the bottom end of the outer circumferential surface of the gear sleeve seat 114, its rotation can be effectively transmitted to the support pipe 54. As the support pipe 54 rotates, the first grinding roller 125 grinds the abrasive on the partition plate 6 to ensure that all the abrasive passes through the grinding process. The fixed disc 121 is fixedly connected with a first scraping plate 127 through the second connecting rod 126, which is used to scrape the ground abrasive into the feeding port 61 to ensure that the abrasive smoothly enters the subsequent mixing and spraying processes. And after the abrasive is fed into the sealed tank 1, it falls into the buffer pipe 81 through the feeding port 61 on the partition plate 6. Under the action of the water flow impact force, the driving rod 84 and the impeller 85 rotate, further enhancing the turbulence effect of the water flow, strongly mixing the abrasive and water, and improving the mixing efficiency and quality. The mixed abrasive and high-speed water flow are ejected through the nozzle 82 at the bottom of the buffer pipe 81, and the nozzle 82 ensures the concentration and high pressure of the water flow, thereby realizing the efficient cutting of the optical film. At the same time, the conveying pipe 83 located directly below the feeding port 61 is fixedly communicated with the buffer pipe 81, ensuring that the abrasive can smoothly enter the buffer pipe 81 for mixing and avoiding the occurrence of blockage. And during the rotation of the support pipe 54, the cleaning brush 137 moves accordingly, continuously cleaning the filter screen 53 to prevent impurities from blocking the holes of the filter screen 53 and ensuring the smooth passage of the water flow and the abrasive. And the second scraping plate 136 is driven by the vertical plate 134 to slide along the inner wall of the sealed tank 1, effectively removing the sediment on the inner wall, keeping the inside of the sealed tank 1 clean, and preventing dirt from affecting the normal operation of the system.
