[0005] The working process and working principle of the above structure are as follows: The plate conveying mechanism starts to work and the first driving assembly drives the movable frame to move horizontally along the guide rail on the fixed support frame. After moving to the top of the foam plate to be transported, the lifting driving device drives the lifting frame to move downward, and the lifting frame drives the suction pipe frame to move downward. The suction cup contacts the foam plate to be moved, and the negative pressure machine works to transmit negative pressure through the corrugated hose and the suction pipe frame, so as to firmly adsorb the plate. The lifting driving device drives the lifting frame to move upward again. After moving to the rated position, the first driving assembly drives the movable frame to continue to move horizontally along the guide rail to transport the plate to the processing position. The lifting driving device drives the lifting frame to move downward, and the negative pressure machine stops working, so that the suction cup and The sheets are detached to realize the sheet conveying operation. The overall automation degree is high, the transportation efficiency is high, and the damage of the foam sheets is reduced. After the cutting height of the heating wire is adjusted on the column, the heating wire is energized, the first reduction motor works, and the first ball screw makes the column move horizontally along the slide rail. The heating wire cuts the foam sheet to realize the cutting operation. When the cutting height needs to be adjusted, it is only necessary to move the mounting seat in the slide slot to adjust the cutting height. When it is necessary to cut an inclined surface, it is only necessary to adjust the mounting seats on the two columns to different heights. By rotating the adjustment roller and releasing a certain length of the heating wire, the height of the two mounting seats can be adjusted and a certain angle can be formed, thereby facilitating bevel cutting, making the cutting function more comprehensive.

[0006] Furthermore, a connecting power cord is arranged on the inner side of the column, and the connecting power cord is connected to the heating wire on the mounting seat. A sliding seat is arranged at the tail end of the mounting seat. The middle part of the sliding seat has the same width as the slide groove, and the width of the part of the sliding seat located inside the slide groove is greater than the slide groove.

[0011] In order to ensure the synchronous lifting and lowering of the four connection positions, the bidirectional drive motor is connected to the commutator through the first transmission shaft. The commutator changes the transmission direction and transmits the power to the reversing seat through the second transmission shaft. The second drive gear in the reversing seat is engaged with the gear rod, driving the gear rod to move up and down, thereby realizing the stable lifting of the lifting frame.

[0012] Furthermore, the suction pipe rack includes a horizontally arranged suction main pipe and a plurality of suction branch pipes, wherein the suction branch pipes are evenly spaced on the suction main pipe and are connected to the suction main pipe, the suction port of the suction branch pipe is downwardly arranged and connected to a suction cup, and the middle part of the upper surface of the suction main pipe is connected to a corrugated hose.

[0013] By setting the suction main pipe and the suction branch pipe, the negative pressure suction force can be evenly distributed to each suction cup, so that the plate can be grasped more firmly.

[0015] Through two lifting motors and two second ball screws, the sliding seat can drive the mounting seat to move in the slide groove, so as to facilitate the synchronous adjustment of the two mounting seats, thereby adjusting the height of the heating wire. When the height of the heating wire needs to be adjusted, the winding roller is rotated to release the length of the heating wire, and the lifting motor is operated at a slow speed to drive the position of the mounting seat to adjust the cutting angle.

[0016] Beneficial effect: The present invention places the foam sheet to be processed on the feed inlet end of the workbench, at which time the sheet conveying mechanism starts to work, and the first driving component drives the moving frame to move horizontally along the guide rail on the fixed support frame. After moving to above the foam sheet to be transported, the lifting driving device drives the lifting frame to move downward, and the lifting frame drives the suction pipe frame to move downward, the suction cup contacts the foam sheet to be moved, the negative pressure machine works, and the negative pressure is transmitted through the corrugated hose and the suction pipe frame, so that the sheet is firmly adsorbed, and the lifting driving device drives the lifting frame to move upward again, and after moving to the rated position, the first driving component drives the moving frame to continue to move horizontally along the guide rail to transport the sheet to the processing position, and the lifting driving device drives the lifting frame to move downward, and the negative pressure machine stops working. Thereby, the suction cup is separated from the plate, and the plate conveying operation is realized. The overall automation degree is high, the transportation efficiency is high, and the damage of the foam plate is reduced. After the cutting height of the heating wire is adjusted on the column, the heating wire is energized, the first reduction motor works, and the first ball screw makes the column move horizontally along the slide rail.
