[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-6 A laser cutting mobile platform includes a support frame 1, a longitudinal gantry 8 with the bottom ends on both sides sliding longitudinally along the top of the support frame 1, a transverse base 9 moving transversely along the top of the longitudinal gantry 8, a laser cutting machine 10 fixed on the transverse base 9, and a plurality of toothed strips 2 with the front and rear ends vertically fixed to the front and rear walls of the inner cavity at the top of the support frame 1. Among them, a plurality of side shafts 1.1 are mounted on the two side walls of the top of the support frame 1. That is, when the laser cutting operation is performed on the plate, the plate is supported on the toothed strips 2, and the longitudinal gantry 8 moves back and forth along the top of the support frame 1. The transverse base 9 carries the laser cutting machine 10 to move transversely to facilitate the laser cutting machine 10 to cut the plate.

[0032] The slag cleaning mechanism 3 includes a plurality of cutting members 3.1 arranged in the transverse direction and extending in the longitudinal direction respectively, and a plurality of cross bars 3.2 arranged in the longitudinal direction and extending in the transverse direction respectively. The top of the cross bar 3.2 is fixedly connected to the bottom end of the cutting member 3.1, and the middle part of the cutting member 3.1 is provided with a groove cavity 3.1.1 that is slidably engaged with the tooth plate strip 2. Among them, the top of the cutting member 3.1 is located on both sides of the groove cavity 3.1.1, and a blade plate 3.1.2 is respectively provided. That is, the tooth plate strip 2 is respectively mounted in the corresponding groove cavity 3.1.1, and the vertical depth of the groove cavity 3.1.1 is greater than the height of the tooth plate strip 2. When the cutting member 3.1 moves upward, the blade plate 3.1.2 respectively scrapes the two side walls of the tooth plate strip 2 to remove the residue on the top of the tooth plate strip 2. Since the residue is formed after the melt generated during the laser cutting process flows, the melt on the top of the tooth plate strip 2 is often connected together in the form of strip-like protrusions. When the blade 3.1.2 scrapes both sides of the tooth plate strip 2, the residue will be taken away as a whole, that is, the residue on the front and rear sides of the tooth tip at the top of the tooth plate strip 2 will be taken away when the residue on both sides of the tooth tip is scraped away.

[0033] The bottom end of the shift fork 4 is rotatably connected to the ends of the crossbar 3.2, and the middle portion of the shift fork 4 is rotatably connected to the side walls of the support frame 1. The bottom end of the shift fork 4 is provided with a bottom hole 4.1 that rotatably connects to the end of the crossbar 3.2, and the middle portion of the shift fork 4 is provided with a center hole 4.2 that rotatably connects to the side shaft 1.1. The top portion of the middle portion of the shift fork 4 is provided with a U-shaped notch 4.3.

[0034] The piston cylinder of the telescopic cylinder 6 is fixed to the rear ends of the two side walls of the top of the support frame 1.

[0035] The linkage 5 comprises longitudinal beams 5.1, mounted on either side of the top of the support frame 1 and extending longitudinally, and a connecting block 5.2, secured to the rear and outer sides of the longitudinal beams 5.1 and securely socketed with the front end of the piston rod of the telescopic cylinder 6. The outer ends of the stub shafts 5.3 are socketed onto the inner sidewalls of the longitudinal beams 5.1, and the inner ends of the stub shafts 5.3 slide and engage within the corresponding U-shaped notches 4.3.

[0036] A bottom groove 7 is provided at the bottom of the inner cavity of the support frame 1, and a slag discharge hole 7.1 is provided at the bottom end of the front wall of the bottom groove 7.

[0037] In summary, when the laser cutting machine 10 performs laser cutting on the plate supported on the tooth plate strip 2, the melt will flow and solidify at the top tooth tip of the tooth plate strip 2. After the laser cutting operation on the plate is completed, the telescopic cylinder 6 pushes and pulls the longitudinal beam 5.1 through the connecting block 5.2, and the short shaft 5.3 drives the fork 4 through the U-shaped notch 4.3 to swing with the side shaft 1.1 as the rotation axis. The bottom of the fork 4 swings upward, thereby pushing the cutting piece 3.1 upward through the cross bar 3.2. The cutting piece 3.1 moves upward relative to the tooth plate strip 2, that is, the blade 3.1.2 scrapes off the residue solidified on the top of the tooth plate strip 2. The scraped residue falls downward and is collected in the bottom trough 7. The residue collected in the bottom trough 7 can be further cleared and emptied through the slag discharge hole 7.1.

[0038] At the inner tops of both ends of the crossbar 3.2 are triangular prisms 3.2.1, and at the bottom of the cutting element 3.1 are corresponding slots 3.1.3 that engage with the triangular prisms 3.2.1. This ensures that residue removed by the blade 3.1.2, when it falls downward, flows smoothly into the bottom groove 7, bypassing the tops of the triangular prisms 3.2.1 and avoiding stagnation at the top of the crossbar 3.2. Furthermore, the secure engagement between the triangular prisms 3.2.1 and the slots 3.1.3 increases the strength and rigidity of the overall connection between the cutting element 3.1 and the crossbar 3.2.
