Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to an automated cutting equipment and cutting method for color film production. Background Technology

[0002] Colored film is a new type of tempered glass decorative material. It breaks away from the traditional process of using tempered photo-printing materials as glass decoration, and thus replaces tempered photo-printing materials to dominate the market for glass sliding doors, glass cabinets, glass background walls and other glass decorative materials.

[0003] In the current technology for processing color film, the color film needs to be cut into the corresponding size according to the usage requirements. In the process of cutting the color film, a cutter is usually used to press and cut the color film. During the pressing and cutting process, the cutter will squeeze and cut the color film. The squeezing and cutting will cause the edges of the cut color film to be stretched, and the edges of the color film are prone to curling after cutting, thus affecting subsequent use. Summary of the Invention

[0004] The purpose of this invention is to provide an automated cutting device and cutting method for color film production, so as to solve the problems mentioned in the background art.

[0008] As a further embodiment of the present invention, the lifting mechanism includes a first groove, which is formed on the surface of the workbench. The first groove is located below the cutting blade and has the same shape as the cutting blade. The left and right sides of the first groove extend through the workbench to the fixed seat. Telescopic plates are hinged to the surface of both sides of the first groove. The ends of the telescopic plates on both sides are hinged to a lifting plate. The lifting plates on both sides extend to the fixed seat. The fixed seat has a second sliding groove corresponding to the lifting plate. A lifting block is elastically slidably connected in the second sliding groove. The lifting block extends into the first groove and is located below the lifting plate. The end of the lifting block near the lifting plate is inclined. An L-shaped extrusion plate is fixedly connected to the surface of the mounting plate. The bottom of the extrusion plate is inclined. The extrusion plate is located above the second sliding groove. The side of the lifting block near the extrusion plate is inclined.

[0009] As a further embodiment of the present invention, the flattening mechanism includes a pressing plate, which is square in shape with the same shape as the cutting blade. The pressing plate is fixedly connected to the bottom of the mounting plate, and the bottom of the pressing plate is flat. The pressing plate is located outside the fixed plate, and a third sliding groove is provided on the bottom of the pressing plate, in which the cutting blade slides elastically.

[0010] As a further embodiment of the present invention, the limiting mechanism includes a limiting groove, which is formed on the inner wall surface of the third sliding groove. A limiting block is elastically slidably connected in the limiting groove. The end of the limiting block is inclined. The limiting block is used to limit the cutting blade. A fourth sliding groove is formed on the inner wall surface of the third sliding groove near the fixed plate. The fourth sliding groove penetrates the fixed plate. A sliding rod is slidably connected in the fourth sliding groove. The sliding rod is located below the limiting block. The end of the sliding rod near the limiting block is inclined. A clearance groove is formed on the upper end of the cutting blade corresponding to the sliding rod position. A toggle block is fixedly connected to the surface of the sliding plate near the sliding rod. A through groove is formed on the surface of the fixed plate corresponding to the toggle block position. The toggle block is located in the through groove.

[0011] As a further embodiment of the present invention, a cleaning brush is fixedly connected to the inner wall surface of the third chute.

[0012] As a further embodiment of the present invention, the fixed base and the surface of the worktable are provided with a plurality of second grooves, and a pull rod is elastically slidably connected in the second groove. The upper end of the pull rod extends to the upper end of the telescopic cylinder, and the telescopic cylinder will drive the pull rod to move when it is fully extended.

[0013] As a further embodiment of the present invention, a U-shaped jacking rod is fixedly connected to the bottom of the pull rod, the end of the jacking rod near the pull rod passing through the second groove, and the end of the jacking rod away from the pull rod passing through the worktable.

[0014] An automated cutting method for color filter production, the specific steps of which are as follows:

[0015] Step 1: Use the winding and conveying equipment to transport the colored film to the surface of the worktable, and start the cutting equipment;

[0016] Step 2: Then the telescopic cylinder retracts, causing the mounting plate and cutting blade to move downwards;

[0017] Step 3: The stretching mechanism will then stretch the color film to keep it flat, and the pressing mechanism will then press the color film firmly.

[0018] Step 4: Then the lifting mechanism will lift the part of the colored film that needs to be cut, and then the cutting blade will cut the colored film;

[0019] Step 5: After cutting is completed, the limiting mechanism will release the limiting effect on the cutting blade;

[0020] Step Six: The flattening mechanism flattens the edges of the cut color film.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the process of cutting colored film, this invention utilizes a sliding plate, a rotating column, and a telescopic block to stretch and flatten the colored film before pressing it. This helps maintain the flatness of the colored film during cutting, preventing wrinkles from forming during transport and affecting the cutting process. Furthermore, a lifting plate raises the cutting position of the colored film during cutting, allowing the cutter to lift the film and providing a certain amount of cutting allowance. This prevents the cutting position from being squeezed and stretched, which could cause curling at the edges of the cut film and affect subsequent use. A pressure plate then promptly flattens the edges of the cut film, ensuring flatness and preventing curling caused by squeezing and stretching during the cutting process from being left untreated and affecting the subsequent use of the colored film.

[0023] 2. In the process of cutting the colored film, after the cutting is completed, the cutting blade will move into the third slide groove. When the cutting blade moves into the third slide groove, the cleaning brush will clean the debris attached to the surface of the cutting blade, ensuring the cleanliness of the cutting blade surface, which is beneficial to the subsequent cutting of the colored film and avoids the debris attached to the surface of the cutting blade during the cutting process, which would cause uneven cutting or failure to cut smoothly.

[0024] 3. In this invention, after the color film is cut, the telescopic cylinder extends and drives the mounting plate to move upward. When the telescopic cylinder is fully extended, it will act on the pulling rod to move upward. The bottom of the pulling rod will pull up the edge of the remaining color film after cutting, which helps to separate the cut color film from the lifting plate, ensuring the transport of the color film, so as to facilitate subsequent cutting of the color film.

[0040] The clamping mechanism includes multiple telescopic blocks 6, all of which are fixedly connected to the bottom of the mounting plate 4, with the telescopic blocks 6 located on the inner side of the cut.

[0041] The stretching mechanism includes four fixed plates 7, which are arranged in a square and fixedly connected to the bottom of the mounting plate 4. The telescopic block 6 is located between the four fixed plates 7. The four fixed plates 7 are located inside the cutting blade 5. The bottom of each of the four fixed plates 7 is bent towards the middle of the mounting plate 4. A first groove 8 is provided on the surface of the fixed plate 7 away from the mounting plate 4. The first groove 8 is inclined. A sliding plate 9 is elastically slidably connected in the first groove 8. A rotating column 10 is rotatably connected to the bottom of the sliding plate 9. The bottom of the rotating column 10 is lower than the bottom of the telescopic block 6.

[0042] The lifting mechanism includes a first groove 11, which is formed on the surface of the workbench 2. The first groove 11 is located below the cutting blade 5 and has the same shape as the cutting blade 5. The left and right sides of the first groove 11 extend through the workbench 2 to the fixed seat 1. The two side walls of the first groove 11 are hinged with telescopic plates 12. The ends of the telescopic plates 12 on both sides are hinged with lifting plates 13. The lifting plates 13 on both sides extend to the fixed seat 1. The fixed seat 1 is provided with a second slide groove 14 corresponding to the lifting plate 13. A lifting block 15 is elastically slidably connected in the second slide groove 14. The lifting block 15 extends into the first groove 11 and is located below the lifting plate 13. The end of the lifting block 15 near the lifting plate 13 is inclined. An L-shaped extrusion plate 16 is fixedly connected to the surface of the mounting plate 4. The bottom of the extrusion plate 16 is inclined. The extrusion plate 16 is located above the second slide groove 14. The side of the lifting block 15 near the extrusion plate 16 is inclined.

[0043] The flattening mechanism includes a flat plate 17, which is square in shape with the same shape as the cutting blade 5. The flat plate 17 is fixedly connected to the bottom of the mounting plate 4. The bottom of the flat plate 17 is flat. The flat plate 17 is located outside the fixed plate 7. A third sliding groove 18 is provided at the bottom of the flat plate 17. The cutting blade 5 slides elastically in the third sliding groove 18.

[0044] The limiting mechanism includes a limiting groove 19, which is formed on the inner wall surface of the third slide groove 18. A limiting block 20 is elastically slidably connected in the limiting groove 19. The end of the limiting block 20 is inclined. The limiting block 20 is used to limit the cutting blade 5. A fourth slide groove 21 is formed on the inner wall surface of the third slide groove 18 near the fixed plate 7. The fourth slide groove 21 penetrates the fixed plate 7. A sliding rod 22 is slidably connected in the fourth slide groove 21. The sliding rod 22 is located below the limiting block 20. The end of the sliding rod 22 near the limiting block 20 is inclined. A clearance groove 23 is formed on the upper end of the cutting blade 5 corresponding to the position of the sliding rod 22. A toggle block 24 is fixedly connected on the surface of the sliding plate 9 near the sliding rod 22. A through groove 25 is formed on the surface of the fixed plate 7 corresponding to the position of the toggle block 24. The toggle block 24 is located in the through groove 25.

[0045] During the production and processing of the colored film, the film moves to the surface of the worktable 2 under the action of the winding conveyor. Then, the winding conveyor stops, and the telescopic cylinder 3 retracts, causing the mounting plate 4 to move closer to the surface of the worktable 2. When the mounting plate 4 moves above the worktable 2, the bottom of the rotating column 10 first contacts the colored film and presses it down. Then, the mounting plate 4 continues to move downwards, and the sliding plate 9 slides into the first chute 8 under the pressure of the mounting plate 4 and the worktable 2. The sliding plate 9 moves along with the rotating column 10, which moves away from the center of the colored film, thus stretching the colored film in four directions. This helps keep the colored film flat during cutting and prevents wrinkles from forming during transport, which would affect its performance. After cutting, the telescopic block 6 contacts the color film surface and presses it firmly, which helps the stretched color film remain stable during cutting. Then, the extrusion plate 16 moves downward to the second slide groove 14. The extrusion plate 16 causes the lifting block 15 to move closer to the lifting plate 13. The lifting block 15 lifts the lifting plate 13 from the bottom, and the telescopic plate 12 extends. The rotating column 10 gradually moves closer to the lifting plate 13 under the action of the sliding plate 9. Then, the cutter moves to the lifting plate 13 and cuts the color film on the surface of the lifting plate 13 along the lifting plate 13. This helps the cutter lift the color film during cutting, providing a certain amount of cutting allowance and preventing the color film from being damaged during cutting. The cutting position is squeezed and stretched, causing the edges of the colored film to curl after cutting, affecting subsequent use. During the cutting process of the cutting blade 5, the sliding plate 9 will drive the actuating block 24 to move together. Then, the actuating block 24 will move closer to the sliding rod 22 in the through groove 25. The actuating block 24 will cause the sliding rod 22 to move closer to the limiting block 20. After the cutting is completed, the sliding rod 22 will cause the limiting block 20 to move into the limiting groove 19. The limiting block 20 will release the limiting of the cutting blade 5. The mounting plate 4 continues to move downward, the cutting blade 5 will move into the third sliding groove 18, and the sliding rod 22 will move into the relief groove 23. Then, the bottom of the pressure plate 17 will move to the surface of the lifting plate 13. The bottom of the pressure plate 17 will... Flattening the edges of the cut film after cutting helps to ensure its flatness and prevents curling caused by compression and stretching during the cutting process, which could affect its subsequent use. After cutting, the telescopic cylinder 3 extends, the mounting plate 4 moves upward, the extrusion plate 16 moves upward along with it, the lifting plate 13 and the telescopic plate 12 move back into the first groove 11, the sliding plate 9 gradually moves out of the first slide groove 8, the cutting blade 5 moves out of the third slide groove 18, and then the limiting block 20 moves out of the limiting groove 19, which again limits the cutting blade 5 to facilitate subsequent cutting.

[0046] After cutting, the surface of the cutting blade 5 is prone to being covered with cutting debris or other impurities, which can affect subsequent cutting. As a further solution of the present invention, a cleaning brush 26 is fixedly connected to the inner wall surface of the third groove 18.

[0047] During the cutting process of the colored film, after the cutting is completed, the cutting blade will move into the third slide groove 18. When the cutting blade 5 moves into the third slide groove 18, the cleaning brush 26 will clean the debris attached to the surface of the cutting blade 5, ensuring the cleanliness of the surface of the cutting blade 5, which is conducive to the subsequent cutting of the colored film and avoids the debris attached to the surface of the cutting blade 5 during the cutting process, which may cause uneven cutting or failure to cut smoothly.

[0048] After the color film is cut, the remaining color film needs to be transported to the surface of the workbench 2. However, during the cutting process, the cut position of the color film is easily attached to the surface of the lifting plate 13. As a further solution of the present invention, the surface of the fixed base 1 and the workbench 2 are provided with a plurality of second grooves 27. A pull rod 28 is elastically slidably connected in the second groove 27. The upper end of the pull rod 28 extends to the upper end of the telescopic cylinder 3. When the telescopic cylinder 3 is fully extended, it will drive the pull rod 28 to move.

[0049] After the color film is cut, the telescopic cylinder 3 extends and drives the mounting plate 4 to move upward. When the telescopic cylinder 3 is fully extended, it will move the pull rod 28 upward. The bottom of the pull rod 28 will pull the edge of the remaining color film after cutting upward, which helps to separate the cut color film from the lifting plate 13, ensuring the transport of the color film and facilitating subsequent cutting of the color film.

[0050] After the color film is cut, the edge of the cut color film will still stick to the surface of the lifting plate 13 under the action of the cutting knife 5 and the pressing plate 17, which is inconvenient to remove. As a further solution of the present invention, a U-shaped push rod 29 is fixedly connected to the bottom of the pull rod 28. The end of the push rod 29 near the pull rod 28 passes through the second groove 27, and the end of the push rod 29 away from the pull rod 28 passes through the worktable 2.

[0051] After the color film is cut, the telescopic cylinder 3 will fully extend and move the pull rod 28 upward. The upward movement of the pull rod 28 will drive the push rod 29 to move upward as well. The push rod 29, located at the bottom end of the color film, will lift the cut color film upward, which will help the color film to detach from the lifting plate 13 and facilitate the removal of the cut color film. This will prevent the cut color film from adhering to the surface of the lifting plate 13 and the worktable 2, which would cause wrinkles at the edge of the color film when it is removed, affecting the use of the color film.

[0052] An automated cutting method for color filter production, the specific steps of which are as follows:

[0053] Step 1: Use the winding and conveying equipment to transport the colored film to the surface of workbench 2, and start the cutting equipment;

[0054] Step 2: Then the telescopic cylinder 3 retracts, causing the mounting plate 4 and the cutting blade 5 to move downwards;

[0055] Step 3: The stretching mechanism will then stretch the color film to keep it flat, and the pressing mechanism will then press the color film firmly.

[0056] Step 4: Then the lifting mechanism will lift the part of the color film that needs to be cut, and then the cutting blade 5 will cut the color film;

[0057] Step 5: After the cutting is completed, the limiting mechanism will release the limiting mechanism on the cutting blade 5; Step 6: The flattening mechanism will flatten the edge of the cut color film.
