[0024] In this embodiment, a screw rod 9 is rotatably connected between the middle parts of the two support plates 3, and the screw rod 9 is threadedly penetrated through the screw plate 11. A threaded hole compatible with the screw rod 9 is opened in the middle of the screw plate 11. A motor 10 is fixedly connected to the outer side of one of the support plates 3. The output end of the motor 10 penetrates the support plate 3 and is fixedly connected to one end of the screw rod 9. The motor 10 is controlled by a PLC controller to realize forward and reverse rotation of the motor 10.

[0025] In this embodiment, a rectangular frame 5 is fixedly sleeved in the middle position of the top of the top plate 1, and a square hole matching the rectangular frame 5 is opened in the middle position of the top of the top plate 1. A plurality of placement bars 501 are fixedly connected at equal distances between the two sides of the inner wall of the rectangular frame 5, and a plurality of triangular grooves are opened on the top of each placement bar 501.

[0026] In this embodiment, racks 503 are fixedly connected to both sides of the outer side of the rectangular frame 5, and strip holes 502 are opened on both sides of the rectangular frame 5 at the top of the racks 503.

The YX moving mechanism 2 is a prior art, which enables the laser cutting mechanism 201 to move freely on the plane, facilitating cutting.

[0029] Working principle: A laser cutting device capable of collecting waste chips. When the YX moving mechanism 2 is cutting and waste chips are generated, the motor 10 is started to rotate the screw rod 9 and move the screw plate 11. The screw plate 11 drives the scraper 7 to move toward the sewage outlet 801, and the waste falling from the gap of the placement bar 501 is scraped into the sewage outlet 801. The waste is collected by the collection drawer 4. At the same time, when the screw plate 11 is close to the sewage outlet 801, the first stop rod 301 will contact the inclined rod 17. Due to the inclined setting of the inclined rod 17, the second right-angled trapezoidal block 15 is driven to approach the first right-angled trapezoidal block 14 until the second right-angled trapezoidal block 15 slides to the bottom of the first right-angled trapezoidal block 14. The scraper 7 rises as a whole, and when the scraper 7 goes back, it will not contact the bottom of the aggregate frame 8. Since the scraper 7 is adapted to the aggregate frame 8, the lifting and lowering of the scraper 7 is in a stable state and will not tilt. When the scraper 7 is close to the other side, the second baffle 302 contacts the inclined rod 17, so that the second right-angled trapezoidal block 15 is separated from the first right-angled trapezoidal block 14. At this time, the scraper 7 falls onto the aggregate frame 8, and the cycle operation is carried out to realize the scraping into the collection drawer 4. At the same time, when the scraper 7 is moving, the connecting rod 603 drives the rotating shaft 6 to move. The cooperation of the gear 601 and the rack 503 enables the wire brush 602 to sweep the gap of the placement strip 501 while moving, so that the scraps can all fall into the aggregate frame 8.
