Description

Technical Field

[0001] The utility model relates to a dust removal device for a laser cutting machine, belonging to the technical field of laser cutting machines. Background Art

[0002] A laser cutting machine emits laser from a laser generator, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of a workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is finally formed in the material, thereby achieving the purpose of cutting.

[0003] Existing laser cutting machines generally do not have a dust removal device. When cutting workpieces, the slag generated by laser cutting will fly everywhere, polluting the working environment. In view of the above deficiencies, the utility model proposes a dust removal device for a laser cutting machine. Summary of the Utility Model

[0020] Please refer to Figures 1 - 5, the present utility model provides a schematic technical solution of a dust removal device for a laser cutting machine: including a frame 1, a laser cutter 2 arranged on the right side of the top surface of the frame 1, a rotary fixture 3 arranged beside the left rear end of the laser cutter 2, and a dust removal device 4 arranged in the left slot of the frame 1. The laser cutter 2 is horizontally aligned with the right end of the dust removal device 4. The left side of the dust removal device 4 extends to the upper part of the left side of the frame 1. The dust removal device 4 includes a moving mechanism 41, an angle adjustment mechanism 42 arranged on the top surface of the moving mechanism 41, and a suction nozzle group 43 hinged to the angle adjustment mechanism 42. The lower end of the suction nozzle group 43 meshes with the middle part of the angle adjustment mechanism 42. The left side of the suction nozzle group 43 is connected with an air suction hose 44, and the other end of the air suction hose 44 is connected with a vacuum cleaner 45. A suction nozzle moving groove 11 is opened on the left side of the top surface of the frame 1, and a suction hose through hole 12 is opened on the left side surface of the frame 1. The moving mechanism 41 includes a sliding seat 411, a slider 412 movably sleeved in the chute on the top surface of the sliding seat 411, and an adjustment screw rod group 413 horizontally threadedly connected to the left side of the sliding seat 411. The adjustment screw rod group 413 is composed of a screw rod and a rotating seat. The right side of the rotating seat is connected to the left side surface of the sliding seat 411. The angle adjustment mechanism 42 includes a rotating base 421, an adjustment rotating shaft 422 horizontally arranged at the lower end of the rotating base 421, and a tooth disc 423 embedded in the left side of the shaft body of the adjustment rotating shaft 422. An adjustment rotating shaft fixing nut 424 is threadedly connected to the right side shaft body of the adjustment rotating shaft 422. The left side surface of the adjustment rotating shaft fixing nut 424 is movably abutted against the right side surface of the rotating base 421. The suction nozzle group 43 includes a suction nozzle 431, a movable base 432 arranged on the bottom surface of the suction nozzle 431, and a semi-circular tooth disc 433 arranged in the cavity at the lower end of the movable base 432. An air outlet 434 is arranged at the left end of the suction nozzle 431. The lower end of the semi-circular tooth disc 433 meshes with the upper end of the tooth disc 423. The suction nozzle 431 is in a semi-circular shape. The suction nozzle 431 is made of stainless steel. The suction nozzle 431 is movably sleeved in the suction nozzle moving groove 11.

[0021] Working principle:

[0022] Before processing, first adjust the distance between the dust suction nozzle 431 and the left end of the laser cutter 2 according to the size of the workpiece to be processed, and adjust the left and right rotation of the dust suction nozzle 431 so that the semi-circular dust suction port at the right end of the dust suction nozzle 431 can semi-wrap the workpiece at the left end, so that the slag generated during the cutting of the laser cutter 2 at the right end can be completely sucked away by the dust suction nozzle 431. By rotating the adjusting screw group 413 at the left end of the sliding seat 411, the slider 412 moves left and right in the chute on the top surface of the sliding seat 411, and the dust suction nozzle group 43 moves left or right in the dust suction nozzle movable groove 11 through the angle adjusting mechanism 42, so as to adjust the distance from the left end of the laser cutter 2. Then, by rotating the adjusting rotating shaft 422, the gear disk 423 is driven to rotate. Through the meshing of the gear disk 423 and the semi-circular gear disk 433, the dust suction nozzle group 43 swings left or right on the rotating base 421, so as to realize the angle adjustment of the dust suction nozzle 431. Then, by tightening the fixing nut 424 of the adjusting rotating shaft, the adjusting rotating shaft 422 is fixed, and the adjustment of the dust suction nozzle group 43 to adapt to the size of the workpiece is completed.

[0023] During cutting, the workpiece to be processed is installed on the rotary fixture 3, and then the laser cutter 2 performs cutting. At this time, the rotary fixture 3 rotates in cooperation, the vacuum cleaner 45 is started, and the slag generated by cutting will be completely sucked away by the left dust suction nozzle 431 and flow into the vacuum cleaner 45 through the suction hose 44.
