Description

Technical Field

[0001] The invention relates to the technical field of leather laser cutting machines, in particular to a laser cutting device for leather processing. Background Art

[0002] In the industrial production process of leather products, the laser cutting machine body has become the core equipment to replace traditional knife die cutting due to its significant advantages such as high cutting precision, no burnt edges, and no damage to leather fibers. It uses high-energy laser beams to instantly melt or vaporize leather materials, and can quickly complete the cutting process of complex patterns. It is especially suitable for the mass production of personalized leather products such as shoe uppers, luggage, and clothing. When using the laser cutting machine body to cut leather, the leather needs to be placed on the grid plate of the laser cutting machine body.

[0003] However, the cutting area of ​​the traditional laser cutting machine body completely overlaps with the loading and unloading area, and both are located in the cutting chamber. After each cutting is completed, it is necessary to wait for the laser cutting component to stop working, extend the arm or upper body into the cutting chamber, remove the cut finished leather from the grid plate one by one, peel off the waste edges, and re-lay the whole piece of leather to be cut. During this process, the laser cutting equipment is in a completely shut down state, and the loading and unloading operations and the cutting process form a rigid time superposition, resulting in extremely long equipment downtime, which seriously restricts the efficiency of mass production. In terms of operational safety, the internal space of the cutting chamber is small, and there are protruding structures such as the laser cutting head, guide slides, and transmission components. When the operator reaches into the body to pick up and place materials, it is easy to collide with these components, and the risk of scratches and bumps is significantly increased, resulting in poor operational safety.

[0004] In terms of cleaning and maintenance of the grid plate, as the core component that supports leather, leather debris, melt residue and other dirt will gradually accumulate on its surface and hollow gaps. If these dirt are not cleaned in time, it will not only affect the flatness of the leather laying (causing cutting offset), but may also cause the grid plate to deform due to high temperature accumulation. The existing grid plate is fixed to the workbench surface with multiple bolts. When disassembling and assembling, the operator needs to hold a wrench and go deep into the cutting cavity to tighten the bolts one by one in the narrow space. Frequent disassembly and assembly operations not only waste working hours, but also cause bolt thread slippage and threaded hole wear due to repeated tightening, reducing the service life of the equipment.

[0018] 3) The fixed structure enables the grille plate to be quickly disassembled, making it easier to clean. When leather of different thicknesses needs to be cut, the position of the laser cutting head can be quickly adjusted by turning the knob, ensuring the cutting effect of leather of different thicknesses.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-10 The present invention provides a technical solution: a laser cutting device for leather processing, comprising a laser cutting machine body 1, two vertical plates 2 fixedly connected to the laser cutting machine body 1, a driving structure 3 provided on the vertical plates 2, two second guide seats 10 fixedly connected to one side of the vertical plates 2, a same movable frame 5 slidably connected between the two opposite second guide seats 10, a grid plate 11 provided on the top side of the movable frame 5, a transposition structure 4 provided on the vertical plates 2, a movable structure 6 provided on the movable frame 5, and a cutting structure 7 provided on the movable structure 6; The transposition structure 4 includes a rotating shaft 401 and a gear 402. The rotating shaft 401 is rotatably connected to the vertical plate 2, and the gear 402 is slidably connected to the rotating shaft 401. Two racks 403 are fixedly connected to the movable frame 5. The two sides of the gear 402 are meshed with the two adjacent racks 403. A sliding sleeve 404 is fixedly connected to one side of the gear 402. The sliding sleeve 404 is slidably connected to the rotating shaft 401. A first plug rod 405 is slidably connected to the sliding sleeve 404. The outer sleeve of the first plug rod 405 is provided with a first spring 406. One end of the first spring 406 is fixedly connected to the first plug rod 405, and the other end of the first spring 406 is fixedly connected to the sliding sleeve 404. Two slots 407 are provided on the rotating shaft 401, and one end of the first plug rod 405 is engaged with one of the slots 407.

[0024] When in use, when the cutting structure 7 cuts the leather on one of the grid plates 11 at a higher position, the other leather to be cut can be laid on the other grid plate 11 at a lower position. When the leather on one of the grid plates 11 is cut, the driving structure 3 can drive the rotating shaft 401 to rotate, and the rotation of the rotating shaft 401 drives the gear 402 to rotate. The rotation of the gear 402 drives the two racks 403 to move in opposite directions. The two racks 403 move at the same time to drive the movable frame 5 to move, and the movable frame 5 drives the grid plates 11 to move synchronously, so that one of the grid plates 11 moves from the inside of the laser cutting machine body 1 to the outside of the laser cutting machine body 1, and the other grid plate 11 moves from the outside of the laser cutting machine body 1 to the inside of the laser cutting machine body 1. Therefore, when cutting the leather on one grid plate 11, the leather can be placed on the other grid plate 11, thereby shortening the downtime and improving the production efficiency. At the same time, since the grid plate 11 is located outside the laser cutting machine body 1 and has a larger space when placed, it can avoid collision, thereby improving the safety of use, and the other grid plate 1 During the movement, the cutting structure 7 is driven to move by the moving structure 6. Since the two grid plates 11 have a certain height difference, the laser cutting head 712 can be kept at a distance from the two grid plates 11 by moving the cutting structure 7, thereby ensuring the cutting effect. When the laser cutting machine body 1 is not needed or only a single or small amount of cutting is required, the first rod 405 can be pulled, and the first spring 406 can be extended. When the first rod 405 is not engaged with one of the slots 407, the gear 402 can be pushed on the rotating shaft 40 1, as the gear 402 moves, the first spring 406 will contract and drive the first insertion rod 405 to engage with the other slot 407. At this time, the gear 402 is not engaged with the rack 403. When the two gears 402 are not engaged with the rack 403, the lower one of the mobile racks 5 can be pushed into the interior of the laser cutting machine body 1, so that the lower one of the mobile racks 5 can be stored, thereby reducing the space occupied and improving the efficiency of space utilization. By setting two second guide seats 10, the mobile rack 5 can be guided in motion.

[0025] A clamping block 408 is fixedly connected to the sliding sleeve 404 , and a clamping seat 409 is provided at the top of the rotating shaft 401 . The clamping seat 409 is fixedly connected to the moving frame 5 .

[0026] During specific use, when the first insertion rod 405 is engaged with another slot 407, the block 408 will be engaged with the base 409, thereby limiting the other movable rack 5 at a higher position, thereby preventing it from moving during single or small batch cutting.

[0027] The cross section of one end of the rotating shaft 401 is a circular structure, and the cross section of the other end of the rotating shaft 401 is a rectangular structure.

[0028] During specific use, when the shaft 401 rotates, it can drive the gear 402 to rotate together.

[0029] The driving structure 3 includes a support plate 301 and a first motor 302. The support plate 301 is fixedly connected to the vertical plate 2, and the first motor 302 is installed on the support plate 301. One of the first synchronous wheels 303 is fixedly connected to the output shaft of the first motor 302, and another first synchronous wheel 303 is fixedly connected to the rotating shaft 401. The same first synchronous belt 304 is wound around the two first synchronous wheels 303.

[0030] During specific use, by starting the first motor 302, the output shaft of the first motor 302 rotates to drive one of the first synchronous wheels 303 to rotate, and one of the first synchronous wheels 303 drives the other first synchronous wheel 303 to rotate through the first synchronous belt 304, and the rotation of the other first synchronous wheel 303 drives the rotating shaft 401 to rotate.

[0031] The movable structure 6 includes a connecting block 601 and a guide shaft 602, wherein two connecting blocks 601 are fixedly connected to one movable frame 5, a guide shaft 602 is fixedly connected to the connecting block 601, two first guide seats 605 are fixedly connected to the vertical plate 2, and the same movable plate 604 is slidably connected between the two first guide seats 605, a guide groove 603 is provided on the movable plate 604, and the guide shaft 602 extends to the inside of the guide groove 603.

[0032] During specific use, when one of the movable frames 5 in the lower position moves, the two connecting blocks 601 will be driven to move. The movement of the connecting block 601 will drive the guide shaft 602 to move inside the guide groove 603. While the guide shaft 602 moves inside the second section of the guide groove 603, the movable plate 604 will slide on the two first guide seats 605. The simultaneous movement of the two movable plates 604 will change the position of the cutting structure 7. Since the two grid plates 11 have a certain height difference, the moving cutting structure 7 can keep the laser cutting head 712 at an appropriate distance from the two grid plates 11 during cutting, thereby ensuring the cutting effect.

[0033] The guide groove 603 has three sections. The directions of the first and second sections are perpendicular to the movement direction of the movable plate 604 . There is a certain angle between the direction of the second section and the movement direction of the movable plate 604 .

[0034] During specific use, when the guide shaft 602 moves inside the first section of the guide groove 603, the movable plate 604 will not move, thereby avoiding collision and damage between the laser cutting head 712 and the grid plate 11. Before the guide shaft 602 moves inside the second section of the guide groove 603, the grid plate 11 will deviate from the bottom end of the laser cutting head 712, so the laser cutting head 712 will not collide with the grid plate 11 during the movement. When the guide shaft 602 moves inside the third section of the guide groove 603, the laser cutting head 712 will not move. At this time, the distance between it and the grid plate 11 is kept at an appropriate distance, thereby ensuring the effect of cutting leather of different thicknesses.

[0035] The cutting structure 7 includes a first connecting seat 701 and a second motor 702. The first connecting seat 701 is fixedly connected to the top side of the movable plate 604. A second connecting seat 705 is slidably connected between the two first connecting seats 701. The second motor 702 is installed on the first connecting seat 701. Two second synchronous wheels 703 are rotatably connected to the first connecting seat 701. The two second synchronous wheels 703 are wrapped with the same second synchronous belt 704. One side of the second connecting seat 705 is fixedly connected to the two second synchronous belts 704. The output shaft of the second motor 702 is fixedly connected to one of the second synchronous wheels 703. Two third synchronous wheels 707 are rotatably connected to the second connecting seat 705. The two third synchronous wheels 707 are wrapped with the same third synchronous belt 708. The third motor 706 is installed on the second connecting seat 705. The output shaft of the third motor 706 is fixedly connected to one of the third synchronous wheels 707. A movable seat 709 is slidably connected to the second connecting seat 705, and the third synchronous belt 708 is fixedly connected to the movable seat 709.

[0036] During specific use, the leather can be cut by moving the laser cutting head 712. When the laser cutting head 712 needs to be moved forward and backward, the two second motors 702 can be started at the same time. The rotation of the output shaft of the second motor 702 will drive one of the second synchronous wheels 703 to rotate, and the rotation of one of the second synchronous wheels 703 will drive the second synchronous belt 704 to move. The simultaneous movement of the two second synchronous belts 704 will cause the second connecting seat 705 to move in the forward and backward directions. When the laser cutting head 712 needs to be moved left and right, the third motor 706 can be started. The rotation of the output shaft of the third motor 706 will drive one of the third synchronous wheels 707 to rotate, and the rotation of one of the third synchronous wheels 707 will drive the third synchronous belt 708 to move. The movement of the third synchronous belt 708 will drive the moving seat 709 to move, and the movement of the moving seat 709 will drive the laser cutting head 712 to move left and right. Therefore, the laser cutting head 712 can be moved in all directions, which is convenient for cutting leather into specific shapes.

[0037] A guide block 710 is fixedly connected to the movable seat 709, a sliding frame 711 is slidably connected to the guide block 710, a laser cutting head 712 is installed on one side of the sliding frame 711, a screw rod 714 is rotatably connected to the sliding frame 711, one end of the screw rod 714 is fixedly connected to a knob 713, and the screw rod 714 and the guide block 710 are threadedly connected.

[0038] During specific use, when it is necessary to cut leather of different thicknesses, the knob 713 can be turned. The rotation of the knob 713 will drive the screw rod 714 to rotate. As the screw rod 714 rotates, the slide frame 711 will slide on the guide block 710, and the laser cutting head 712 will move with the slide frame 711, thereby realizing rapid adjustment of the position of the laser cutting head 712 to ensure the cutting effect.

[0039] The movable frame 5 is provided with a fixed structure 8, which includes a connecting shaft 801 and a stop block 802. The movable frame 5 is rotatably connected to the connecting shaft 801, and the stop block 802 is fixedly connected to the connecting shaft 801. The stop block 802 conflicts with one side of the grille plate 11. The connecting shaft 801 is fixedly connected to a rocker arm 803, and a second plug rod 804 is slidably connected to the rocker arm 803. One end of the second plug rod 804 is engaged with the movable frame 5. A second spring 805 is provided on the outside of the second plug rod 804. One end of the second spring 805 is fixedly connected to the second plug rod 804, and the other end of the second spring 805 is fixedly connected to the rocker arm 803. Two sockets 807 are fixedly connected to the movable frame 5, and two positioning shafts 806 are fixedly connected to the other side of the grille plate 11. The positioning shaft 806 is engaged with the adjacent sockets 807, and the grille plate 11 conflicts with the sockets 807.

[0040] During specific use, when the grille plate 11 needs to be disassembled and cleaned, the second plug rod 804 can be pulled, and the second spring 805 will extend. When the second plug rod 804 is not engaged with the movable frame 5, the rocker arm 803 can be rotated, and the rotation of the rocker arm 803 drives the connecting shaft 801 to rotate, and the rotation of the connecting shaft 801 drives the stop block 802 to rotate. When the stop block 802 does not resist the grille plate 11, the grille plate 11 can be pulled to disengage the positioning shaft 806 and the socket 807. At this time, the grille plate 11 can be quickly disassembled, thereby shortening the disassembly time and facilitating the cleaning and maintenance of the grille plate 11.

[0041] A limiting structure 9 is provided on the vertical plate 2, and the limiting structure 9 includes a limiting block 901 and a limiting groove 902. The limiting block 901 is fixedly connected to the vertical plate 2, and two limiting grooves 902 are provided on the movable frame 5. One end of the limiting block 901 extends to the inside of the adjacent limiting groove 902.

[0042] During specific use, the limit block 901 will move inside the limit groove 902 during the movement of the mobile frame 5. The movement of the limit block 901 inside the limit groove 902 can limit the movement range of the mobile frame 5, thereby preventing the mobile frame 5 from detaching from the inside of the second guide seat 10.

[0043] Working principle: The laser cutting head 712 can be controlled to move in all directions through the second motor 702 and the third motor 706. The laser cutting head 712 can cut the leather during the movement. When leather of different thicknesses needs to be cut, the position of the laser cutting head 712 can be adjusted by turning the knob 713.

[0044] When the laser cutting head 712 is cutting the leather on one of the higher grid plates 11, the other leather to be cut can be laid on the other lower grid plate 11. When the leather on one of the grid plates 11 is cut, the first motor 302 can be started. Under the action of the first motor 302, the other grid plate 11 can be moved from the outside of the laser cutting machine body 1 to the inside of the laser cutting machine body 1. When one of the grid plates 11 moves from the inside of the laser cutting machine body 1 to the outside of the laser cutting machine body 1, the vertical position of the laser cutting head 712 changes during the movement of the other grid plate 11 to ensure that the distance between it and the grid plate 11 remains unchanged during the cutting process.

[0045] When the first rod 405 is engaged with one of the slots 407, the gear 402 will mesh with two adjacent racks 403. When cutting is not required, the first rod 405 can be engaged with the other slot 407. At this time, the gear 402 will not mesh with the rack 403. Then, one of the lower movable racks 5 can be pushed into the interior of the laser cutting machine body 1. When the first rod 405 is engaged with the other slot 407, the base 409 will be engaged with the block 408, so that the other higher movable rack 5 can be limited and fixed.

[0046] When the grille plate 11 needs to be disassembled and cleaned, the second plug rod 804 can be pulled. When the second plug rod 804 is not engaged with the movable frame 5, the rocker arm 803 can be rotated. The rotation of the rocker arm 803 drives the connecting shaft 801 to rotate. The rotation of the connecting shaft 801 drives the stop block 802 to rotate. When the stop block 802 does not resist the grille plate 11, the grille plate 11 can be pulled to disengage the positioning shaft 806 and the socket 807.
