Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 , an elastic buffer device for a laser cutting machine, comprising a machine platform 1, wherein the upper and lower side walls of the machine platform 1 are fixedly connected with a slider 101, and a slide rail 102 is provided on the surface of the slider 101, and further comprising:

[0025] Two plates 2 are slidably connected to the inner wall of the slide rail 102, a connecting plate 201 is fixedly connected to the side wall of the plate 2, a first spring 202 is fixedly connected between the connecting plate 201 and the machine 1, a sliding hole is opened in the inner cavity of the slider 101, a second spring 203 is fixedly connected to the inner wall of the sliding hole, and a support column 204 is fixedly connected to the side wall of the plate 2 inside the slide rail 102, and the support column 204 can extend to the inner cavity of the sliding hole;

[0026] The adjacent sides of the plate 2 are fixedly connected with magnetic stickers 205, and the bottom of the machine 1 is rotatably connected with a roller 206;

[0027] A fixing frame 3 is fixedly connected to both sides of the inner wall of the machine 1, a pressing plate 301 is slidably connected to the inner wall of the fixing frame 3, a third spring 302 is fixedly connected between the pressing plate 301 and the fixing frame 3, and a first threaded bolt 303 is threadedly connected to the top of the fixing frame 3;

[0028] It should be noted that when installing the material, the plate 2 is first slid toward the outside of the machine 1. At this time, the first spring 202 is stretched, and then the material to be cut is placed in the inner cavity of the fixing frame 3. The elastic force of the third spring 302 is used to drive the pressure plate 301 to position the material inside the fixing frame 3, and then the first threaded bolt 303 is rotated. The bottom end of the first threaded bolt 303 contacts the pressure plate 301, thereby fixing the material. When cutting is required, the elastic force of the first spring 202 is used to drive the plate 2 to move toward the center of the slider 101, and the support column 204 at the bottom of the plate 2 will first enter the inner cavity of the sliding hole. Since the inner cavity of the sliding hole is provided with a second spring 203, when the plate 2 slides in the inner cavity of the slide rail 102 opened on the surface of the slider 101, it will be buffered by the elastic force of the second spring 203, so as to avoid collision when the plate 2 is closed, causing the machine 1 to vibrate and the laser cutting line to bend. At the same time, the plate 2 will be attached to each other due to the magnetic stickers 205 provided on its side walls, so as to avoid impurities and cooling water from flowing out of the machine 1 during cutting.

[0029] Reference Figure 1-4 , sliding columns 304 are fixedly connected to both sides of the inner wall of the machine 1, and square blocks 305 are slidably connected to the outer wall of the sliding columns 304, and connecting columns 306 are fixedly connected between the square blocks 305;

[0030] The outer wall of the connecting column 306 is slidably connected to a controller 307, a laser cutting knife 308 is fixedly connected to the bottom of the controller 307, a motor 309 is fixedly connected to the top of the machine 1, and a connecting line 310 is fixedly connected between the motor 309 and the controller 307;

[0031] It should be noted that: when cutting, the motor 309 and the connecting line 310 are used to control the controller 307 to slide on the outside of the connecting column 306, and at the same time control the square block 305 to slide on the outer wall of the sliding column 304, thereby adjusting the cutting direction of the laser cutting knife 308, which is convenient for adjusting the cutting route.

[0032] Reference Figure 1-4 The side wall of the controller 307 is fixedly connected with a mounting frame 4, and the side wall of the mounting frame 4 is threadedly connected with a second threaded bolt 401;

[0033] The end of the second threaded bolt 401 is rotatably connected to a fixed plate 402, a water spray head 403 is clamped between the fixed plate 402 and the mounting frame 4, a water tank 404 is fixedly connected to the side wall of the machine 1, a water pump 405 is fixedly connected to the top of the water tank 404, and a water pipe 406 is fixedly connected between the water pump 405 and the water spray head 403;

[0034] A filter plate 407 is fixedly connected to the bottom of the inner wall of the machine 1, a connecting pipe 408 is fixedly connected between the water tank 404 and the machine 1, and a filter assembly 409 is fixedly connected to the outer wall of the connecting pipe 408;

[0035] It should be noted that: by rotating the second threaded bolt 401, the second threaded bolt 401 drives the fixed plate 402 to move, clamping the water spray head 403 in the middle, and the angle of the water spray head 403 can be adjusted so that the water spray head 403 can always be aligned with the cutting direction of the laser cutting knife 308, and the water pump 405 is used to drive the water in the inner cavity of the water tank 404 to flow to the water spray head 403 through the water pipe 406. During cutting, the water spray head 403 will move with the laser cutting knife 308, so that the water sprayed by the water spray head 403 can always be aligned with the cutting position, which can not only remove impurities generated by cutting, but also cool the material to prevent the material from overheating. Impurities and water flow to the filter plate 407 set on the inner wall of the machine 1, and the impurities are filtered, while the cooling water will be filtered from the connecting pipe 408 and flow to the inside of the water tank 404, so that it can be reused to save water.

[0036] Operation method: When installing the material, first slide the plate 2 to the outside of the machine 1, at this time the first spring 202 is stretched, and then the material to be cut is placed in the inner cavity of the fixing frame 3, and the elastic force of the third spring 302 is used to drive the pressing plate 301 to position the material inside the fixing frame 3, and then the first threaded bolt 303 is rotated. The bottom end of the first threaded bolt 303 contacts the pressing plate 301, so that the material is fixed. When cutting is required, the elastic force of the first spring 202 is used to drive the plate 2 to move toward the center of the slider 101, and the support column 204 at the bottom of the plate 2 will first enter the inner cavity of the sliding hole. Since the inner cavity of the sliding hole is provided with a second spring 203, when the plate 2 slides in the inner cavity of the slide rail 102 opened on the surface of the slider 101, it will be buffered by the elastic force of the second spring 203, so as to avoid collision when the plate 2 is closed, causing the machine 1 to vibrate and the laser cutting line to bend. At the same time, the plate 2 will be attached to each other due to the magnetic stickers 205 provided on its side walls, so as to avoid impurities and cooling water from flowing out of the machine 1 during cutting;

[0037] When cutting, the motor 309 and the connecting line 310 are used to control the controller 307 to slide on the outside of the connecting column 306, and the square block 305 is controlled to slide on the outer wall of the sliding column 304, thereby adjusting the cutting direction of the laser cutting knife 308, which is convenient for adjusting the cutting route. The second threaded bolt 401 is rotated, and the second threaded bolt 401 drives the fixed plate 402 to move, clamping the water spray head 403 in the middle, and the angle of the water spray head 403 can be adjusted so that the water spray head 403 can always be aligned with the cutting direction of the laser cutting knife 308, and the water spray head 403 can be adjusted by the water spray head 403. The pump 405 drives the water in the inner cavity of the water tank 404 to flow to the water spray head 403 through the water pipe 406. During cutting, the water spray head 403 will move with the laser cutting knife 308, so that the water sprayed by the water spray head 403 can always be aimed at the cutting position, which can not only remove impurities generated by cutting, but also cool the material to prevent the material from overheating. The impurities and water flow to the filter plate 407 set on the inner wall of the machine 1, and the impurities are filtered, while the cooling water will be filtered from the connecting pipe 408 and flow to the inside of the water tank 404, so it can be reused to save water.
