[0020] At the corresponding positions of the top of the support beam 2 to the positions of the conveyor rollers 3, there are grooves to prevent interference between the conveyor rollers 3 and the support beam 2 when the conveyor rollers 3 drop below the top of the support tooth plate 4; an anti-slip protective layer made of rubber material is provided on the outer surface of the conveyor rollers 3 to further improve the protection effect on the plates and ensure the convenience of loading and unloading. In addition, according to actual usage requirements, the rubber material can also be replaced with graphite material to increase its service life; rotary bearings are provided between the support frame 1 and the first rotating shaft 5, between the first rotating shaft 5 and the rotary support plate 7, and between the second rotating shaft 9 and the fixed mounting plate 8 to facilitate the smooth rotation of the first rotating shaft 5 and the second rotating shaft 9; the rotary support plate 7 is connected to the support frame 1 by means of bolt connection to facilitate later maintenance and repair; the telescopic device 13 is electrically connected to the laser cutting machine control center to facilitate controlling the working state of the telescopic device 13, and the telescopic device 13 is one of a cylinder or an electric telescopic rod.

[0021] Working principle: When the plate needs to be loaded onto the workbench, by controlling the telescopic device to work, the connection position between the telescopic device and the driving arm is at the highest point. During the process of the telescopic device driving the driving arm to move, the first rotating shaft will rotate accordingly. With the cooperation of the swing support seat, the fixed mounting plate, the second rotating shaft and the rotary bearing, the top of the conveyor roller will rise above the top of the support tooth plate when the connection position between the telescopic device and the driving arm is at the highest point. Then the plate can be placed on the upper part of the conveyor roller. Under the conveyance of the conveyor roller, the plate is pushed to the designated position. After the position is adjusted, the telescopic device can be controlled to work in the reverse direction. According to the above steps, finally, the highest point of the conveyor roller is lower than the highest point of the support plate. After the plate processing is completed, control the telescopic device to start working, so that the conveyor roller drives the plate to leave the support tooth plate, and then under the conveyance of the conveyor roller, the plate is removed from the workbench.
