[0002] The laser cutting machine uses a high-power focused laser to irradiate the sheet material, and the instantaneous high temperature of the laser causes the material in the irradiated area to evaporate, thereby achieving the cutting of the sheet material. The existing laser cutting machine for warning sign sheets has fixed cutting parameters, that is, the sheet material is cut using preset cutting parameters during the cutting process. Existing warning plates made of various metal materials are generally cut by laser, such as existing power warning signs.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention rotates the one-way screw, the cross rail slides along the side rail, the movement of the shaft rod causes the inner support plate and the outer push plate to slide along the plug plate, and at the same time the length of the inner two-way telescopic plate and the outer two-way telescopic plate becomes longer, the two-way screw rotates, and the two moving seats cooperate with the two-way screw to slide along the inside of the cross rail. Because the moving seat is connected to the inner support plate and the outer support plate on the same side through a connecting rod, and the outer two-way telescopic plate is connected to the outer support plate through a connecting plate and a vertical plate, the inner two-way telescopic plate and the inner support plate are connected by the fourth electric push rod to keep synchronous movement, and can be adjusted simultaneously. The spacing between the inner and outer bidirectional telescopic plates, that is, the width of the cut warning sign, is determined by the sliding engagement of the rotating sleeve with the convex strip of the shaft rod, so the rotating sleeve can slide along the shaft rod with the inner and outer support plates and maintain the rotational force of the shaft rod on it, thereby adjusting the inner and outer wrapping range of the limit assembly, and adjusting it according to different warning sign processing needs. Because the inner and outer support plates are connected by a connecting rod and a rotating seat, the spacing between the four sides of the inner and outer bidirectional telescopic plates is always the same and can be adjusted synchronously.

[0017] 2. The present invention drives the connecting plate of the outer bidirectional telescopic plate to slide along the vertical plate through the third electric push rod, so as to cooperate with the outer support plate to clamp and fix the plate, and can clamp and send out the cut scraps. The fourth electric push rod is inserted into the inner support plate. When the inner support plate adjusts its position along with the driving component, the inner bidirectional telescopic plate can be adjusted synchronously. In the process of feeding the plate for cutting, the fourth electric push rod needs to be retracted to avoid interference in cutting.

[0018] 3. The present invention connects the outer end of the plug-in plate of the inner support plate to the first electric push rod, and the outer end of the plug-in plate of the outer support plate is connected to the support column through a ball, so as to maintain the stability of the inner and outer support plates in supporting the plates after they are placed. The support column is installed inside the moving frame and can be automatically adjusted along with the movement of the outer push plate. The outer support plate is inserted into the top of the support column through the ball. When the outer push plate is flipped upward by the action of the shaft rod, it will not be interfered by the support column.

[0019] 4. The present invention connects the fixed plate with the fixed side of the inner two-way telescopic plate through the second electric push rod. The second electric push rod can drive the entire inner two-way telescopic plate to descend and cooperate with the inner support plate to clamp the cut part of the warning sign. It can also squeeze downward and cooperate with the folding and contraction of the inner support plate driven by the first electric push rod to rotate the cut part of the warning sign downward and send it out. Because the shafts of the inner support plate and the outer support plate are rotatably connected by gears, the outer support plate will push the cut scraps to flip upward, which is convenient for quickly separating the warning sign and the scraps.

[0020] 5. The present invention inserts the laser welding device into the cutting seam of the limiting assembly through the cylinder of the slide. At this time, the guide wheel slides and is clamped on the guide belt. The length of the guide belt can be installed according to the length of the space enclosed by the inner two-way telescopic plate. Guided by the guide wheel, the laser cutting device moves along the cutting seam for cutting, and the slide slides along the inside of the slide frame. The rebound effect is maintained by the first spring. The first motor drives the rotation of the turntable, so that the laser welding device moves through the entire cutting seam for laser cutting.

[0021] 6. Compared with the prior art, the limiting assembly of the present invention can clamp and fix warning signs of different sizes, and the adjustment is convenient. Moreover, by adjusting the position of the inner two-way telescopic plate and the outer two-way telescopic plate, a cutting gap is left for the cutting device to move, and the laser cutting device is guided and limited. After cutting, the warning sign and scraps are separated and transported to two directions, which is convenient for manual removal of the required warning sign and improves processing efficiency.
