When working, place the piece to be cut on the support bar 12, then turn on the motor 9, the motor 9 drives the first threaded rod 10 to rotate, and the left and right threaded parts are used to drive the two clamping seats 33 to move toward each other, thereby treating the Both ends of the cutting piece are clamped and fixed, and when the two clamping bases 33 move toward each other, the outer end of the clamping block 36 first contacts the to-be-cut piece, and then the to-be-cut piece presses the clamping block 36 so that the The toothed plate 35 squeezes the third spring 37 and moves toward the drive cavity 34, thereby driving the driving gear 39 to rotate, and the driving gear 39 drives the second threaded rod 38 to rotate, so that the second threaded rod 38 drives the pressure plate 40 to move down, Realize the pressing of the workpiece to be cut, so as to realize the limit fixation in the horizontal and vertical directions of the workpiece to be cut, and then turn on the robotic arm 6 and the laser cutting head 7 to cut the workpiece to be cut, and simultaneously turn on the fan 16 to remove the waste gas generated by cutting. The waste gas is filtered and purified by the dust filter screen 31 and the activated carbon adsorption screen 15 through the collection net 22, the first through groove 19 and the second through groove 25. At the same time, the waste generated by cutting passes through the guide plate 14 When the collecting net 22 is impacted by the waste, the first spring 20 will drive the sliding frame 21 to oscillate up and down, and the sliding frame 21 will pass through the first spring 20. The second sliding rail 29 and the second sliding groove 28 drive the sliding seat 27 to oscillate up and down, and the sliding seat 27 drives the dust filter screen 31 to oscillate up and down through the connecting frame 30, so as to shake off the particles under the dust filter screen 31, so that the collecting net 22 is in the buffer At the same time, the dust filter screen 31 can be cleaned, so that the device can work normally and the service life of the device can be prolonged.

To sum up, through the structural arrangement of the clamping structure, the functions of protecting the collecting net 22 and cleaning the dust filter net 31 by the impact force of the dropping of the scrap are realized when the scrap is collected.
