DETAILED DESCRIPTION

[0029] 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. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] When it is necessary to cut the sheet, the worker first disassembles the second rectangular rod 20, and then places the stacked sheets on the placement table 21 through other auxiliary equipment, and then installs the second rectangular rod 20. Then the grabbing mechanism grabs the sheet on the placement table 21 and places it on the conveyor roller 4 to be conveyed to the feed port of the cutting machine 1, and then the sheet is cut by the cutting mechanism 2. When the grabbing mechanism grabs a sheet, the placement table 21 will move upward by the distance of a sheet to facilitate the grabbing under the grabbing mechanism. After the placement table 21 moves to a specific position, it will stop moving, and then it will automatically fall to the initial position and wait for the placement of the sheet, thereby realizing the automatic cutting of the sheet, which not only improves the cutting efficiency but also reduces the workload of the workers.
