[0002] Laser cutting machines focus the laser light emitted from a laser generator into a high-power density laser beam through an optical system. The laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] In the specification of a feeding device of a laser cutting machine in the prior art (Announcement No. CN213614857U), it is mentioned that "mounting frames are provided on both sides of the adjacent feed port of the frame, and the two mounting frames include a first mounting plate and a second mounting plate. The upper side surface of the first mounting plate and the bottom wall of the feed port are coplanar. A feeding trolley is mounted on the frame, and the feeding trolley includes a first feeding trolley and a second feeding trolley. The first feeding trolley is slidably provided on the two first mounting plates on both sides of the adjacent feed port respectively." However, after the workpiece is placed on the feeding device in the prior art, the feeding movement is not stable and is prone to shaking or skewing, which leads to skewed cutting, and the waste chips generated by the cutting fall on the feeding device and are difficult to clean, so it is not stable and practical. Utility Model Content

[0004] In order to overcome the defects of the existing technology, a laser cutting machine loading device is provided to solve the problem that after the workpiece is placed on the loading device in the existing technology, the feeding movement is unstable and prone to shaking or tilting, which leads to skewed cutting, and the waste chips generated by the cutting fall on the loading device and are difficult to clean, which is not stable and practical.

[0005] In order to achieve the above-mentioned purpose, a laser cutting machine feeding device is provided, including a frame, a chip receiving bin and a feeding structure, wherein support columns are provided at the four corners of the frame, and first Y linear guide rails are provided on the left and right sides of the upper end face of the frame, a lower platform is provided at the lower part of the frame, and a chip receiving bin is provided on the lower platform, first sliders are provided at both ends of the left and right ends of the feeding structure, and the first slider is slidably connected to the first Y linear guide rail on the same side, and a front splint and a rear splint are movably provided on the front and rear parts of the feeding structure, and a workpiece is clamped between the front splint and the rear splint.

[0006] Furthermore, a discharge port is provided at the rear end of the chip receiving bin, and side handles are fixed to the rear portions of the left and right sides of the chip receiving bin, and the chip receiving bin is detachably connected to the frame.

[0007] Furthermore, a scraper is installed in the front of the chip receiving bin, and two sets of pull rods are fixed on the rear side of the scraper. The rear of the pull rod is installed in the socket provided on the outer baffle, and a rear handle is provided at the rear end of the pull rod, and the scraper, outer baffle and chip receiving bin are split and connected.

[0008] Furthermore, multiple sets of railings are provided in the feeding structure, and the left and right parts of the feeding structure are provided with a second Y linear guide rail and a third Y linear guide rail, and the left and right parts of the front splint are provided with side fixing plates, and the lower end of the side fixing plate is provided with a second slider, the second slider is slidably connected to the second Y linear guide rail, and the left and right parts of the rear splint are slidably connected to the third Y linear guide rails on both sides.

[0009] Furthermore, two sets of mounting brackets are fixed to the front side surfaces of the side fixing plates to which the left and right parts of the front splint are fixed, and rubber extrusion blocks are installed in the mounting brackets, and the rubber extrusion blocks are extruded on the outer side surfaces of the workpiece.

[0010] Furthermore, the front plate and the rear plate are bilaterally symmetrical about the center line of the feeding structure, and the rear plate has the same structural arrangement as the front plate.

[0011] The beneficial effects of the present invention are:

[0012] 1. The chip bin of the utility model is placed on the lower platform on the lower side of the frame.

[0024] In this embodiment, a discharge port 20 is provided at the rear end of the chip receiving bin 2, and side handles 21 are fixed to the rear of the left and right sides of the chip receiving bin 2, and the chip receiving bin 2 and the frame 1 are split and connected; a scraper 22 is sleeved on the front of the chip receiving bin 2, and two sets of pull rods 23 are fixed on the rear side of the scraper 22, the rear part of the pull rod 23 is sleeved in the sleeve 26 provided on the outer baffle 24, and the rear end of the pull rod 23 is provided with a rear handle 25, and the scraper 22, the outer baffle 24 and the chip receiving bin 2 are split and connected.

[0025] As a preferred embodiment, the chip receiving bin 2 of the present invention is placed on the lower platform 12 on the lower inner side of the frame 1, so that when the loading structure 3 moves to the rear half of the first Y linear guide rail 11, the waste chips generated by the workpiece on the loading structure 3 during laser cutting will fall into the chip receiving bin 2, making it more convenient and hassle-free to receive the waste chips and dust.

[0026] When the scraper 22 is placed on the front side wall of the chip receiving bin 2, the outer baffle 24 is just blocked at the discharge port 20, which is convenient for removing waste chips. When regularly emptying the waste chips, the rear handle 25 can be pulled horizontally backward, which will drive the scraper 22 and the sleeve 26 to move backward together. At this time, the scraper 22 will scrape the waste chips in the chip receiving bin 2 to the rear side, and the waste chips moved backward will come out through the discharge port 20, which is easier and more convenient.

[0028] As a preferred embodiment, the feeding structure 3 of the utility model is slidably connected to the first Y linear guide rail 11 through the first sliders 30 at the left and right ends, which is convenient for feeding in and out of the upper part of the frame 1. When the workpiece 4 is placed on the feeding structure 3, the front clamping plate 33 moves backward on the second Y linear guide rail 32, and the rear clamping plate 34 moves forward on the third Y linear guide rail 39, so that the rubber extrusion blocks 38 on the front clamping plate 33 and the rear clamping plate 34 can be used to stably press on the front and rear sides of the workpiece 4, so that it can clamp the workpiece safely and firmly, thereby ensuring the cutting stability of the laser cutting machine and making it safer and more reliable to use.

[0029] The utility model can effectively solve the problems in the prior art that after the workpiece is placed on the loading device, the feeding movement is unstable and easily shakes or tilts, which leads to skewed cutting, and the waste chips generated by cutting fall on the loading device and are difficult to clean, which is unstable and impractical.
