Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser cutting device for metal coils. Background Technology

[0002] Metal coils are core raw materials in automobile manufacturing, home appliance production, building decoration, and electronic information industries. Their processing efficiency and precision directly determine the quality and production capacity of downstream products. Before the popularization of laser technology, the cutting of metal coils relied on traditional mechanical processing methods for a long time. However, with the upgrading of the manufacturing industry's demand for "high precision, high flexibility, and high efficiency", laser cutting technology has gradually become the mainstream.

[0003] Patent CN117484198A discloses an automatic laser cutting and welding device for metal coils. The device includes an operating table. A conveying mechanism is fixed to one end of the top surface of the operating table. A cutting mechanism is fixed to the top surface of the operating table above the conveying mechanism. A welding mechanism is slidably connected to the top surface of the operating table on one side of the cutting mechanism. A winding mechanism is provided at the other end of the top surface of the operating table. A pressing mechanism is fixedly connected to the top surface of the operating table above the winding mechanism. In this device, two cylinders drive a roller to move downwards, pressing the cut coil into small segments into a U-shaped structure. Then, through… Four movable arc-shaped plates sliding within two support seats can bend the U-shaped sheet material along the outer wall of the circular roller until the sheet material is wrapped around the outer wall of the circular roller under the action of the four arc-shaped plates. This can realize the winding of sheet material cut into small sections into a cylindrical structure. Although this device can clamp and fix the workpiece through a clamping mechanism, improving the overall stability of cutting, the device is prone to causing material bending and deformation during fixing, making it difficult to eliminate stress during the cutting process, resulting in cutting errors and reducing cutting accuracy. Therefore, a laser cutting device for metal coils is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a laser cutting device for metal coils, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a laser cutting device for metal coils, including a cutting table, a processing coil disposed on the front side of the cutting table, an electric slide rail fixedly connected to the top of the cutting table, a movable slide rail mounted on the output end of the electric slide rail, a fixed rod fixedly connected to the bottom of the movable slide rail, a pulley mounted on the side of the fixed rod away from the electric slide rail, a guide plate slidably connected to the top of the cutting table, fixed housings fixedly connected to the front and rear sides of the guide plate, a pressure roller rotatably connected to the inner wall of the fixed housing, a positioning cylinder fixedly connected to the front side of the cutting table, and an mounting platform mounted on the front side of the movable slide rail, the mounting platform having openings on both sides... A rotating plate is hinged to a torsion spring, and a flattening cylinder is rotatably connected to the inner wall of the rotating plate. A sliding laser cutting head is installed on the front side of the mounting platform, and connecting rods are hinged to both sides of the sliding laser cutting head. When laser cutting the processing roll material, the moving slide rail moves, driving the pressure roller to move in conjunction with the positioning cylinder to flatten and tighten the processing roll material passing through the middle. Automatic flattening and tightening of the material helps to eliminate internal stress in the material, making the material flatter and thus improving the cutting quality. After uncoiling, the leveling machine flattens the metal plate and eliminates the stress in the plate during the leveling process, making the plate material flatter and suitable for cutting. This helps to reduce cutting errors caused by uneven material, improve cutting accuracy and yield. The top of the electric slide rail is equipped with a graphite coating mechanism for applying graphite powder. The inner wall of the graphite coating mechanism is equipped with an anti-clogging mechanism to prevent clogging. The processing roll material contacts the top of the cutting table. The inner wall of the guide plate has a C-shaped guide groove, and the circumferential surface of the pulley contacts the guide groove on the inner wall of the guide plate. The guide plate will move along the trajectory of the pulley. The circumferential surface of the pressure roller contacts the top of the processing roll material, the circumferential surface of the positioning cylinder contacts the bottom of the processing roll material, and the circumferential surface of the flattening cylinder contacts the top of the processing roll material. The front side of the rotating plate is hinged to the rear side of the connecting rod. Simultaneously, when pressed, the flattening cylinder will be driven by the moving slide rail to spread and flatten the area to be cut by the sliding laser cutting head to both sides, thereby improving the flatness of the metal sheet, simplifying the production process, improving production efficiency and product quality, ensuring the stability and consistency of the material during the cutting process, and thus improving the quality of the final product.

[0006] Preferably, the graphite coating mechanism includes a storage box, with an ink outlet fixedly connected to the bottom of the storage box. A movable column is slidably connected to the inner wall of the storage box via a spring, and a baffle is fixedly connected to the top of the movable column. When the processed roll material passes between the pressure roller and the positioning cylinder, the guide plate moves up to open the ink outlet, thereby enabling the equipment to achieve automatic powder dispensing. Graphite powder has good lubricity and high temperature resistance, which helps to reduce friction between the material and the tool during the cutting process, thereby reducing wear and improving processing efficiency. The lubricity of graphite powder remains good at high temperatures, which may help reduce thermal damage and material deformation during laser cutting. At the same time, the indirect automatic powder dispensing reduces the cost of cutting. A rotating cylinder is rotatably connected to the inner wall of the ink outlet. A pulley assembly is fixedly connected to the left side of the rotating cylinder; the top of the electric slide rail is fixedly connected to the bottom of the storage box; the front pulley shaft of the pulley assembly is fixedly connected to the left side of the pressure roller; the bottom of the moving column contacts the top of the guide plate. As the processing roll material is fed in, the rotation of the pressure roller drives the pulley assembly to rotate and coat graphite powder, thereby forming a thin and uniform graphene coating on the substrate. Rotary coating has certain application value in material processing and coating preparation, and can achieve a uniform coating effect.

[0007] Preferably, the anti-clogging mechanism includes a reciprocating lead screw, with gears two fixedly connected to both sides of the reciprocating lead screw, a scraper movably connected to the circumferential surface of the reciprocating lead screw, and gear one fixedly connected to the circumferential surface of the rotating cylinder. When graphite is applied, the rotation of the rotating cylinder will drive the scraper to clean the powder remaining on its circumferential surface, avoiding the rotating cylinder from clogging the transfer of graphite powder, helping to maintain a clean working environment, reducing the impact on the environment and the health of operators, not only helping to improve the service life of the equipment, but also improving the quality of processed products and reducing processing errors caused by equipment wear; A cam is fixedly connected to the right side of the rotating cylinder, a connecting rod is hinged to the right side of the cam, and a fixed plate is hinged to the rear side of the connecting rod. A long plate is slidably connected to the rear side of the ink outlet, and a pressing plate is fixedly connected to the bottom of the long plate. The rear side of the ink outlet is rotatably connected to the circumferential surface of the reciprocating lead screw. The circumferential surface of gear one meshes with the circumferential surface of gear two. The inner wall of the scraper contacts the circumferential surface of the rotating cylinder. The top of the long plate is fixedly connected to the bottom of the fixed plate. While applying graphite powder, the rotation of the rotating cylinder drives the pressing plate to reciprocate and flatten the applied graphite powder, further improving the coating effect of the graphite powder and making the graphite powder coating more uniform. This can improve the operating efficiency of the equipment, reduce downtime caused by equipment failure, and thus improve the overall production efficiency.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This laser cutting equipment for metal coils, through the coordinated operation of a cutting table, processing coil, electric slide rail, moving slide rail, mounting table, sliding laser cutting head, fixed rod, pulley, guide plate, fixed shell, pressure roller, positioning cylinder, connecting rod, rotating plate, and flattening cylinder, enables laser cutting of the processing coil. During laser cutting, the moving slide rail moves, driving the pressure roller to move in conjunction with the positioning cylinder to flatten and tighten the processing coil passing through the center. Automatic flattening and tightening of the material helps eliminate internal stress, making the material flatter and thus improving cutting quality. After uncoiling... The leveling machine flattens the metal sheet and eliminates stress during the leveling process, making the material flatter and more suitable for cutting. This helps reduce cutting errors caused by uneven material, improving cutting accuracy and yield. Simultaneously, after clamping, the moving slide rail drives the flattening cylinder to spread and flatten the area to be cut by the sliding laser cutting head to both sides, further improving the flatness of the metal sheet, simplifying the production process, increasing production efficiency and product quality, ensuring the stability and consistency of the material during cutting, and ultimately improving the quality of the final product.

[0009] 2. This laser cutting equipment for metal coils, through the coordinated operation of the storage box, moving column, baffle, and ink outlet, allows the guide plate to move upward and open the ink outlet when the processed coil passes between the pressure roller and the positioning cylinder, thereby enabling the equipment to achieve automatic powder dispensing. Graphite powder has good lubricity and high temperature resistance, which helps to reduce friction between the material and the tool during the cutting process, thereby reducing wear and improving processing efficiency. The lubricity of graphite powder remains good at high temperatures, which may help reduce thermal damage and material deformation during laser cutting. At the same time, the indirect automatic powder dispensing reduces the cutting cost.

[0010] 3. This laser cutting equipment for metal coils, through the coordinated operation of a rotating drum and a pulley assembly, allows the processing coil to be fed in while the pressure roller rotates, driving the pulley assembly to rotate and coat graphite powder, thereby forming a thin and uniform graphene coating on the substrate. Rotary coating has certain application value in material processing and coating preparation, and can achieve a uniform coating effect.

[0011] 4. This laser cutting equipment for metal coils, through the coordinated operation of gear one, gear two, reciprocating lead screw, and scraper, allows the rotating drum to clean the powder remaining on its circumference while graphite is being applied. This prevents the rotating drum from clogging the graphite powder transfer, helps maintain a clean working environment, reduces the impact on the environment and the health of operators, not only helps to extend the service life of the equipment, but also improves the quality of processed products and reduces processing errors caused by equipment wear.

[0012] 5. This laser cutting equipment for metal coils, through the coordinated operation of the cam, connecting rod, fixed plate, long plate, and pressure plate, while applying graphite powder, the rotating cylinder drives the pressure plate to reciprocate and flatten the applied graphite powder, further improving the coating effect of graphite powder, making the graphite powder coating more uniform, improving the operating efficiency of the equipment, reducing downtime caused by equipment failure, and thus improving the overall production efficiency.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-9 One embodiment of the present invention is: a laser cutting device for metal coils, including a cutting table 1, a processing coil 2 is provided on the front side of the cutting table 1, an electric slide rail 3 is fixedly connected to the top of the cutting table 1, a movable slide rail 4 is installed at the output end of the electric slide rail 3, a fixed rod 9 is fixedly connected to the bottom of the movable slide rail 4, a pulley 10 is installed on the side of the fixed rod 9 away from the electric slide rail 3, a guide plate 11 is slidably connected to the top of the cutting table 1, a fixed shell 12 is fixedly connected to the front and rear sides of the guide plate 11, a pressure roller 13 is rotatably connected to the inner wall of the fixed shell 12, a positioning cylinder 14 is fixedly connected to the front side of the cutting table 1, an installation platform 5 is installed on the front side of the movable slide rail 4, a rotating plate 16 is hinged to both sides of the installation platform 5 by a torsion spring, a flattening cylinder 17 is rotatably connected to the inner wall of the rotating plate 16, a sliding laser cutting head 6 is installed on the front side of the installation platform 5, and a connecting rod 15 is hinged to both sides of the sliding laser cutting head 6; When laser cutting the processing roll 2, first install the processing roll 2 into the corresponding position. Then, start the electric slide rail 3. The electric slide rail 3 will drive the moving slide rail 4 to move through its output end. The movement of the moving slide rail 4 will move the fixed rod 9, which in turn will drive the pulley 10 to move. The pulley 10 will then contact the inner wall of the guide plate 11 through its circumferential surface. At this time, the guide plate 11 will move downwards through the C-shaped guide groove on its inner wall according to the movement of the pulley 10. The moving fixed shell 12 moves, which drives the pressure roller 13 to move. The movement of the pressure roller 13, together with the positioning cylinder 14, flattens and tightens the processing coil 2 passing through the middle. Automatic flattening and tightening of the material helps to eliminate the internal stress of the material, making the material flatter and thus improving the cutting quality. After uncoiling, the leveling machine flattens the metal plate and eliminates the stress of the plate during the leveling process, making the plate material flatter and suitable for cutting. This helps to reduce the cutting error caused by uneven material and improve the cutting accuracy and yield. The top of the electric slide rail 3 is provided with a graphite coating mechanism 7 for applying graphite powder. The inner wall of the graphite coating mechanism 7 is provided with an anti-clogging mechanism 8 to prevent clogging. The processing roll 2 is in contact with the top of the cutting table 1. The inner wall of the guide plate 11 is provided with a C-shaped guide groove, and the circumferential surface of the pulley 10 is in contact with the guide groove on the inner wall of the guide plate 11. The guide plate 11 will move through the movement trajectory of the pulley 10. The circumferential surface of the pressure roller 13 is in contact with the top of the processing roll 2. The circumferential surface of the positioning cylinder 14 is in contact with the bottom of the processing roll 2. The circumferential surface of the flattening cylinder 17 is in contact with the top of the processing roll 2. The front side of the rotating plate 16 is hinged to the rear side of the connecting rod 15. Simultaneously, after clamping, the mounting table 5 will be moved to the corresponding cutting position via the sliding slide rail 4. At this time, the sliding laser cutting head 6 will be moved down for calibration via the output end of the mounting table 5. At this time, the downward movement of the rotating plate 16 will drive the connecting rod 15 to move down through the hinge point. The downward movement of the connecting rod 15 will drive the rotating plate 16 to move to both sides through the hinge point. The movement of the rotating plate 16 to both sides will drive the flattening cylinder 17 to move to both sides, so that the flattening cylinder 17 will flatten the part that the sliding laser cutting head 6 needs to cut to both sides, thereby improving the flatness of the metal sheet, simplifying the production process, improving production efficiency and product quality, ensuring the stability and consistency of the material during the cutting process, and thus improving the quality of the final product.

[0017] Working principle: When laser cutting the processing coil 2, the moving slide rail 4 moves, driving the pressure roller 13 to move in conjunction with the positioning cylinder 14 to flatten and tighten the processing coil 2 passing through the middle. Automatic flattening and tightening of the material helps to eliminate internal stress in the material, making the material flatter and thus improving the cutting quality. This helps to reduce cutting errors caused by uneven material, improve cutting accuracy and yield. At the same time, after being tightened, the moving slide rail 4 drives the flattening cylinder 17 to spread and flatten the area to be cut by the sliding laser cutting head 6 to both sides, which is used to improve the flatness of the metal sheet, simplify the production process, and improve production efficiency and product quality.

[0018] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the graphite coating mechanism 7 includes a storage box 71, an ink outlet 74 is fixedly connected to the bottom of the storage box 71, a movable column 72 is slidably connected to the inner wall of the storage box 71 by a spring, and a baffle 73 is fixedly connected to the top of the movable column 72. When the processing roll 2 passes between the pressure roller 13 and the positioning cylinder 14, the storage box 71 will be filled with graphite powder by the operator. At this time, the sliding laser cutting head 6 is not in the cutting state and is in the initial position. At this time, the pulley 10 will drive the guide plate 11 to move upward. The guide plate 11 will contact the bottom of the moving column 72 through the top, thereby driving the moving column 72 to move upward. The moving column 72 will drive the baffle 73 to move upward. The baffle 73 will open the powder outlet of the storage box 71, allowing the powder to enter the ink outlet 74. When cutting begins, the moving column 72 will be driven to reset by the spring between it and the storage box 71. The moving column 72 will drive the baffle 73 to reset, thereby enabling the equipment to achieve automatic powder dispensing. Graphite powder has good lubricity and high temperature resistance, which helps to reduce friction between the material and the tool during the cutting process, thereby reducing wear and improving processing efficiency. The lubricity of graphite powder remains good at high temperatures, which may help reduce thermal damage and material deformation during laser cutting. At the same time, the indirect automatic powder dispensing reduces the cutting cost. A rotating cylinder 75 is rotatably connected to the inner wall of the ink outlet 74. A pulley assembly 76 is fixedly connected to the left side of the rotating cylinder 75; the top of the electric slide rail 3 is fixedly connected to the bottom of the storage box 71, the front pulley shaft of the pulley assembly 76 is fixedly connected to the left side of the pressure roller 13, and the bottom of the moving column 72 contacts the top of the guide plate 11. As the processing roll 2 is fed in, the pressure roller 13 rotates upon contact with the processing roll 2. The rotation of the pressure roller 13 drives the front pulley of the pulley assembly 76 to rotate. The front pulley of the pulley assembly 76 drives the rear pulley to rotate via a belt. The rear pulley of the pulley assembly 76 drives the rotating cylinder 75 to rotate via its shaft. This causes the pulley assembly 76 to rotate and apply graphite powder, thereby forming a thin and uniform graphene coating on the substrate. Rotary application has certain application value in material processing and coating preparation, and can achieve a uniform coating effect.

[0019] Working principle: When the processing roll 2 passes between the pressure roller 13 and the positioning cylinder 14, the guide plate 11 moves upward to open the ink outlet 74, thereby enabling the equipment to automatically dispense powder. The graphite powder has good lubricity and high temperature resistance, which helps to reduce friction between the material and the tool during the cutting process, thereby reducing wear and improving processing efficiency. As the processing roll 2 is fed in, the rotation of the pressure roller 13 will drive the pulley group 76 to rotate and apply graphite powder, thereby forming a thin and uniform graphene coating on the substrate. Rotary application has certain application value in material processing and coating preparation, and can achieve a uniform coating effect.

[0020] The anti-clogging mechanism 8 includes a reciprocating lead screw 83, gear 2 82 fixedly connected to both sides of the reciprocating lead screw 83, a scraper 84 movably connected to the circumferential surface of the reciprocating lead screw 83, and gear 1 81 fixedly connected to the circumferential surface of the rotating cylinder 75. While graphite is being applied, the rotation of the rotating cylinder 75 drives the first gear 81 to rotate. The rotation of the first gear 81 meshes with the second gear 82 through its circumferential surface, thereby driving the second gear 82 to rotate. The rotation of the second gear 82 drives the reciprocating screw 83 to rotate. The rotation of the reciprocating screw 83 contacts the inner wall of the scraper 84 through the reciprocating groove on its circumferential surface, thereby driving the scraper 84 to move back and forth. The reciprocating movement of the scraper 84 cleans the powder remaining on the circumferential surface of the rotating cylinder 75, preventing the rotating cylinder 75 from clogging the transfer of graphite powder. This helps to maintain a clean working environment, reducing the impact on the environment and the health of operators. It not only helps to extend the service life of the equipment, but also improves the quality of the processed products and reduces processing errors caused by equipment wear. A cam 85 is fixedly connected to the right side of the rotating cylinder 75. A connecting rod 86 is hinged to the right side of the cam 85. A fixed plate 87 is hinged to the rear side of the connecting rod 86. A long plate 88 is slidably connected to the rear side of the ink outlet 74. A pressing plate 89 is fixedly connected to the bottom of the long plate 88. The rear side of the ink outlet 74 is rotatably connected to the circumferential surface of the reciprocating screw 83. The circumferential surface of gear 1 81 meshes with the circumferential surface of gear 2 82. The inner wall of the scraper 84 contacts the circumferential surface of the rotating cylinder 75. The top of the long plate 88 is fixedly connected to the bottom of the fixed plate 87. While the graphite powder is being applied, the rotating cylinder 75 rotates, causing the cam 85 to rotate. The rotation of the cam 85 drives the connecting rod 86 to reciprocate through the hinge point. The reciprocating movement of the connecting rod 86 drives the fixed plate 87 to move up and down through the hinge point. The fixed plate 87 drives the long plate 88 to move up and down, and the long plate 88 drives the pressing plate 89 to move up and down. Thus, the pressing plate 89 reciprocates and flattens the applied graphite powder, further improving the application effect of the graphite powder and making the graphite powder more evenly applied. This can improve the operating efficiency of the equipment, reduce downtime caused by equipment failure, and thus improve the overall production efficiency.

[0021] Working principle: While applying graphite, the rotating drum 75 rotates, which drives the scraper 84 to clean the powder remaining on its circumference. This prevents the rotating drum 75 from clogging the graphite powder transfer, helps maintain a clean working environment, and reduces the impact on the environment and the health of operators. This not only helps to extend the service life of the equipment but also improves the quality of the processed products. At the same time as applying graphite powder, the rotation of the rotating drum 75 drives the pressure plate 89 to reciprocate and flatten the applied graphite powder, further improving the coating effect of the graphite powder and making the graphite powder more evenly applied, which can improve the operating efficiency of the equipment.
