[0011] Among them, the first motor is connected to the tool changing assembly, the shearing knife is connected to the tool changing assembly, the second motor is connected to the screw rod, the screw rod is matched with the fixed assembly, and the third motor is connected to the fixed assembly.

[0012] In the present technical scheme, a cutting mechanism and a position adjustment mechanism are arranged in the device body, and a first motor, a knife changing assembly and a shearing knife are arranged in the cutting mechanism. The first motor is connected to the knife changing assembly, and the shearing knife is connected to the knife changing assembly. When the staff cuts the plastic cup cover on the device body, by controlling the rotation of the first motor, the shearing knife can rotate along the edge of the plastic cup cover, and the plastic cup cover can be quickly cut out. The cutting efficiency is high, and there is no need to adjust the position of the plastic cup cover multiple times, thereby improving the cutting accuracy. A second motor, a third motor, a screw rod and a fixing assembly are arranged in the position adjustment mechanism. The second motor is connected to the screw rod, the screw rod cooperates with the fixing assembly, and the third motor is connected to the fixing assembly.
