Description

Technical Field

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

[0002] Optical film is a thin film material with specific optical properties, which 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 anti-reflection film, reflective film, filter film, etc. For the cutting of optical films, its material properties, precision requirements, size and protection of optical properties must be comprehensively considered. Different optical film substrates may have different hardness, brittleness or toughness, which directly affects the choice of use method. For example, for optical films that are very thick or composed of multiple layers of different materials, traditional mechanical cutting may cause problems such as edge burrs, cracks or delamination; while laser cutting has difficulty in achieving uniform energy distribution due to thickness problems, which may lead to incomplete cutting or material damage. In this case, the use of water jet becomes the best choice.

[0003] Water jet cutting is a technology that uses high-speed water 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 materials, thus ensuring the quality and accuracy of the cutting. However, when processing certain special materials, such as composite optical films on automotive glass or high-strength protective films for industrial use, a simple water jet may not be enough to provide sufficient cutting force. In order to improve cutting efficiency and quality, it is usually necessary to add an appropriate amount of abrasive to the high-speed water stream.

[0004] Although adding abrasives can significantly enhance cutting capabilities, optical films of different materials have different requirements for 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 brittle materials, finer abrasives should be used to reduce the impact on the material surface. Therefore, in order to ensure the best cutting effect, the corresponding abrasive particle size needs to be changed according to the specific material during the operation. However, this process is relatively cumbersome and difficult to quickly adapt to the diverse needs in actual production, which increases the complexity of the operation and time cost.

[0016] A method for using an optical film cutting device, the method comprising the following steps: S1: Connect the water inlet pipe to the external high-pressure water supply equipment, and add the required abrasive into the sealed tank through the feeding pipe. At this time, start the external high-pressure water supply equipment, so that the high-pressure water flows from the water inlet pipe into the sealed tank and flows downward through the circulation pipe; S2: The high-pressure water flow impacts the blades inclined at a 45-degree angle set on the inner wall of the gear blade disc, generating sufficient torque to drive the gear blade disc to rotate, so that the meshing gear sleeve seat drives the gear sleeve seat to rotate synchronously, and then the support tube rotates.

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) This scheme is provided with a support mechanism, a driving mechanism, and a grinding mechanism. When in use, the grinding mechanism located at the bottom of the support tube can adjust its movement intensity according to the change of water flow pressure; when the water flows into the sealed tank, its flow rate directly affects the rotation speed of the gear blade disk, thereby changing the working intensity of the grinding mechanism. 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; and after the abrasive is properly ground and mixed with the high-speed water flow, it is sprayed out through the nozzle 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.

[0018] (2) By setting up a jet mixing mechanism, when the high-pressure water flows into the sealed tank from the water inlet pipe and flows downward through the circulation pipe, the impact force of the water flow is used to rotate the impeller. The rotation of the impeller not only achieves efficient mixing of abrasive and water, but also significantly improves the quality and efficiency of optical film cutting. At the same time, in the process of jet cutting using the mixed high-speed water flow, the reasonable layout of the delivery pipe and the buffer pipe and the continuous stirring action of the impeller effectively prevent abrasive accumulation and pipe blockage, thereby ensuring the long-term stable operation of the system.

[0019] (3) By providing a grinding mechanism, during the rotation of the support tube, the fixed disk is rotated synchronously by the first connecting rod, and the first grinding roller is driven to rotate on the partition by the L-shaped support rod, so that the first grinding roller grinds the abrasive on the partition, and the first scraper can scrape the ground abrasive into the discharge port, ensuring that the abrasive smoothly enters the subsequent mixing and injection process; and during the rotation of the fixed disk, since the outer diameter of the blocking block is larger than the outer diameter of the discharge port, the abrasive can be prevented from falling directly into the buffer tube through the discharge port without being processed, ensuring that all abrasives can be ground.

[0024] The following is a detailed description of an optical film cutting device and a method of using the optical film provided by the present invention in combination with the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 7 As shown, an embodiment of the present invention provides an optical film cutting device and a method for using the same, comprising a sealed can 1, a sealed cover 2 is threadedly connected to the top of the sealed can 1, a water inlet pipe 3 is fixedly connected to the middle of the top of the sealed cover 2, and a feeding pipe 4 for conveying abrasive is arranged on one side of the top of the sealed cover 2; a flow pipe 7 is arranged in the middle of the inside of the sealed can 1, a supporting mechanism 5 for supporting the flow pipe 7 is arranged on the inner wall of the sealed can 1, a partition 6 is fixedly connected to the bottom end of the inner wall of the sealed can 1, and both sides of the inside of the partition 6 are provided with a feed opening 61, a spray mixing mechanism 8 for spraying a high-pressure water flow containing abrasive is arranged at the bottom of the flow pipe 7, and a driving mechanism 11 is arranged at the top of the flow pipe 7; The support mechanism 5 includes a support tube 54 disposed inside the sealed tank 1, a first fixing ring 51 and a second fixing ring 52 fixedly connected to the inner wall of the sealed tank 1 are disposed at both ends of the outer circumferential surface of the support tube 54, a first support plate 55 for support is fixedly connected to both ends of the outer circumferential surface of the support tube 54, a receiving sleeve 56 is fixedly connected to the top of the support tube 54, and a grinding mechanism 12 for abrasive processing is disposed at the bottom of the support tube 54; Among them, the driving mechanism 11 includes a support seat 111 fixedly connected to the middle of the inner top wall of the circulation pipe 7, the support seat 111 is internally rotatably connected to a support rod 112, the outer cylindrical surface of the support rod 112 is rotatably connected to a gear impeller 113, the outer cylindrical surface of the gear impeller 113 is meshingly connected to a gear sleeve seat 114; and the outer cylindrical surface of the gear sleeve seat 114 is threadedly connected to the receiving sleeve 56.

[0026] like Figure 1 , Figure 2 As shown, the first fixed ring 51 and the second fixed ring 52 jointly form a first movable groove for the first support plate 55 to move, the inner walls of the first fixed ring 51 and the second fixed ring 52 are fixedly connected with a filter 53 for filtering impurities in the abrasive, and two third fixed rings 57 are fixedly connected to the bottom of the support tube 54, and the two third fixed rings 57 jointly form a second movable groove.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] When the 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 feed pipe 4 and falls into the buffer tube 81 through the discharge port 61 on the partition 6. Under the impact of the water flow, the abrasive and water begin to mix preliminarily. Since a rotating rod 84 is provided inside the buffer tube 81, its two ends are fixedly connected to the inner wall of the buffer tube 81 through the limit sleeve 86, ensuring the stability and rotational freedom of the rotating rod 84. When the high-pressure water flow passes through the buffer tube 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 that the two are evenly distributed, and improving the mixing efficiency and quality. The mixed abrasive and high-speed water flow are sprayed out through the nozzle 82 at the bottom of the buffer tube 81. By setting the nozzle 82, the concentration and high pressure of the water flow are guaranteed, thereby achieving efficient cutting of the optical film. At the same time, the delivery pipe 83 located directly below the discharge port 61 is fixedly connected to the buffer pipe 81, ensuring that the abrasive can smoothly enter the buffer pipe 81 for mixing, avoiding the occurrence of blockage. In addition, during the above operation, since the outer circumferential surface of the circulation pipe 7 is surrounded by a second support plate 10, the support plate is movably connected to the second movable groove formed by the third fixed ring 57, thereby ensuring the stability of the circulation pipe 7 and its related components during operation. The fixed sleeve 9 is used to further enhance the mechanical strength and stability of the entire injection mixing mechanism 8 to prevent vibration or displacement caused by high-pressure water flow.

[0031] like Figure 2 , Figure 3 As shown, the inner wall of the gear impeller 113 is provided with blades which are inclined at an angle of 45 degrees to the horizontal plane of the support seat 111, and the blades are used to drive the gear impeller 113 to rotate due to the impact of water flow. The outer cylindrical surface of the gear impeller 113 is gear-shaped, and the inner wall of the gear sleeve 114 is provided with a toothed disk meshing with the gear impeller 113. The bottom end of the outer cylindrical surface of the gear sleeve 114 is provided with a threaded ring which is threadedly connected to the support tube 54 to facilitate subsequent disassembly and cleaning.

[0032] like Figure 1 , Figure 5 As shown, the grinding mechanism 12 includes a fixed plate 121 arranged at the bottom of the support tube 54, the fixed plate 121 and the support tube 54 are fixedly connected to a first connecting rod 122, both sides of the bottom of the fixed plate 121 are fixedly connected to blocking blocks 123, the bottom of the fixed plate 121 is fixedly connected to an L-shaped support rod 124, the outer surface of the L-shaped support rod 124 is rotatably connected to a first grinding roller 125, the bottom of the fixed plate 121 is fixedly connected to a second connecting rod 126, and the fixed plate 121 is fixedly connected to a first scraper 127 via the second connecting rod 126.

[0033] like Figure 1 , Figure 5As shown, the outer diameter of the blocking block 123 is larger than the outer diameter of the feed opening 61 , and the outer surfaces of the first scraper 127 and the first grinding roller 125 are both in contact with the upper surface of the partition 6 .

[0034] The 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 inclined at an angle of 45 degrees set on the inner wall of the gear blade disc 113, generating sufficient torque to drive the gear blade disc 113 to rotate. Since the outer cylindrical surface of the gear blade disc 113 is gear-shaped and meshes with the toothed disc set on the inner wall of the gear sleeve seat 114, when the gear blade disc 113 rotates, the gear sleeve seat 114 is driven to rotate synchronously. At the same time, since the bottom end of the outer cylindrical surface of the gear sleeve seat 114 is provided with a threaded ring threadedly connected to the support tube 54, it is ensured that the rotation of the gear sleeve seat 114 can be effectively transmitted to the support tube 54. This threaded connection design is not only convenient for subsequent disassembly and cleaning, but also enhances the stability and reliability of the system. In the process of the rotation of the support tube 54, the first connecting rod 122 is used to make the fixed disk 121 rotate synchronously, and the L-shaped support rod 124 is used to drive the first grinding roller 125 to rotate on the partition 6, and the first grinding roller 125 is used to grind the abrasive on the partition 6. The first scraper 127 can scrape the ground abrasive into the discharge port 61, ensuring that the abrasive smoothly enters the subsequent mixing and spraying process. During the rotation of the fixed disk 121, since the outer diameter of the blocking block 123 is larger than the outer diameter of the discharge port 61, the abrasive can be prevented from directly passing through the discharge port 61 and falling into the buffer tube 81 without being processed, ensuring that all abrasives can be ground.

[0035] like Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, a cleaning mechanism 13 is provided on the outer circumferential surface of the support tube 54, and the cleaning mechanism 13 includes an annular tube 131 arranged on one side of the outer circumferential surface of the support tube 54, and a support 132 is fixedly connected to the side of the annular tube 131 close to the support tube 54, and a second grinding roller 133 is rotatably connected to the side of the annular tube 131 close to the sealing tank 1.

[0036] like Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the cleaning mechanism 13 also includes a vertical plate 134 arranged on the other side of the outer circumferential surface of the support tube 54, and connecting plates 135 fixedly connected to the support tube 54 are arranged at both ends of the inner side of the vertical plate 134, and cleaning brushes 137 for cleaning the filter 53 are fixedly connected at both ends of the vertical plate 134, and a second scraper 136 for cleaning dirt on the inner wall of the sealed tank 1 is fixedly connected to the outer side of the vertical plate 134.

[0037] After the abrasive enters the sealed tank 1, it is filtered by the multi-layer filter 53 to remove other larger impurities in the abrasive, thereby ensuring the purity of the abrasive used in the subsequent grinding and cutting process and improving the cutting effect. However, due to the long-term use of the filter 53, its holes are easily blocked and need to be cleaned regularly to ensure that it does not affect normal use. Therefore, when the high-pressure water flow drives the gear blade 113 to rotate, the entire support tube 54 and its attached cleaning mechanism 13 rotate synchronously. As a result, when the support tube 54 rotates, the annular tube 131 rotates with it, driving the second grinding roller 133 to further grind the passing abrasive. At the same time, the support tube 54 drives the cleaning brush 137 and the second scraper 136 to rotate simultaneously through the connecting plate 135 and the vertical plate 134, so that the cleaning brush 137 cleans the filter 53 in the first fixed ring 51 and the second fixed ring 52. Specifically, when the support tube 54 rotates, the cleaning brush 137 moves accordingly, continuously cleaning the filter 53, preventing impurities from clogging the holes of the filter 53, and ensuring smooth passage of water and abrasives. As the support tube 54 rotates, the second scraper 136 slides 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. Due to the continuous cleaning action of the cleaning brush 137 and the second scraper 136, the filter 53 is prevented from being blocked and dirt is accumulated on the inner wall of the sealed tank 1, reducing the maintenance frequency and extending the service life of the equipment.

[0038] The method of use provided by the present invention is as follows: S1: Connect the water inlet pipe 3 to the external high-pressure water supply equipment, and add the required abrasive into the sealed tank 1 through the feeding pipe 4. At this time, start the external high-pressure water supply equipment, so that the high-pressure water flows from the water inlet pipe 3 into the sealed tank 1 and flows downward through the circulation pipe 7; S2: The high-pressure water flow impacts the blades inclined at a 45-degree angle arranged on the inner wall of the gear blade disk 113, generating sufficient torque to drive the gear blade disk 113 to rotate, so that the meshing gear sleeve 114 drives the gear sleeve 114 to rotate synchronously, and then the support tube 54 rotates. As the support tube 54 rotates, the abrasive on the partition plate 6 is ground by the first grinding roller 125 to ensure that all the abrasive can be fully ground, and the first scraper 127 scrapes the ground abrasive into the discharge port 61 to ensure that the abrasive smoothly enters the subsequent mixing and injection process; 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 port 61 on the partition 6. Under the impact of the water flow, the rotating rod 84 and the impeller 85 are driven to rotate, further enhancing the turbulent effect of the water flow, so that the abrasive and water are strongly mixed; S4: The mixed abrasive and high-speed water flow are ejected through the nozzle 82 at the bottom of the buffer tube 81 , and the optical film is cut efficiently by the nozzle 82 .

[0039] When the present invention is in use, the water inlet pipe 3 is first connected to an external high-pressure water supply device, and the required abrasive is added to the sealed tank 1 through the feed pipe 4. After the external high-pressure water supply device is started, the high-pressure water 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 inclined at a 45-degree angle set on the inner wall of the gear blade disk 113, generating sufficient torque to drive the gear blade disk 113 to rotate. The outer cylindrical surface of the gear blade disk 113 is gear-shaped, meshing with the toothed disk set on the inner wall of the gear sleeve 114, driving the gear sleeve 114 to rotate synchronously. Since the bottom end of the outer cylindrical surface of the gear sleeve 114 is provided with a threaded ring threadedly connected to the support tube 54, its rotation can be effectively transmitted to the support tube 54. As the support tube 54 rotates, the first grinding roller 125 grinds the abrasive on the partition 6 to ensure that all abrasives can be ground. The fixed plate 121 is fixedly connected to the first scraper 127 through the second connecting rod 126, which is used to scrape the ground abrasive into the discharge port 61 to ensure that the abrasive smoothly enters the subsequent mixing and spraying process. After the abrasive is fed into the sealed tank 1, it falls into the buffer tube 81 through the discharge port 61 on the partition 6. Under the impact of the water flow, the rotating rod 84 and the impeller 85 are driven to rotate, further enhancing the turbulent effect of the water flow, and the abrasive and water are strongly mixed, thereby improving the mixing efficiency and quality. The mixed abrasive and high-speed water flow are sprayed out through the nozzle 82 at the bottom of the buffer tube 81, and the nozzle 82 ensures the concentration and high pressure of the water flow, thereby achieving efficient cutting of the optical film. At the same time, the delivery pipe 83 located directly below the discharge port 61 is fixedly connected to the buffer tube 81, ensuring that the abrasive can smoothly enter the buffer tube 81 for mixing, avoiding the occurrence of blockage. In addition, during the rotation of the support tube 54, the cleaning brush 137 moves accordingly, continuously cleaning the filter screen 53 to prevent impurities from clogging the holes of the filter screen 53, ensuring smooth passage of water and abrasives. The second scraper 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.
