[0071] In some embodiments, a controller is also included.

[0072] After the first cup assembly is assembled on the main machine, the first cup assembly can apply a force to the first connecting rod assembly and the second upper limit connecting rod assembly; after the second upper limit connecting rod assembly is subjected to the force, it can act to drive the second upper limit micro switch to move in a direction away from the knife group assembly until the second upper limit micro switch is in a position where it does not contact the knife group assembly. At this time, the first connecting rod assembly just triggers the first micro switch; the first micro switch gives the controller a signal, the controller controls the motor to rotate forward, and the motor drives the knife group assembly to move upward along the axial direction to the trigger member to trigger the first upper limit micro switch; the first upper limit micro switch gives the controller a signal, the controller controls the motor to rotate reversely, and the motor drives the knife group assembly to move downward along the axial direction to the trigger member to trigger the lower limit micro switch, and the lower limit micro switch gives the controller a signal, and the controller controls the motor to stop running;

[0073] After the second cup assembly is assembled to the main machine, the second cup assembly can apply a force to the first connecting rod assembly and the second upper limit connecting rod assembly; so that the first connecting rod assembly triggers the first microswitch. At this time, the second upper limit connecting rod assembly does not drive the second upper limit microswitch to move in a direction away from the knife group assembly, and the second upper limit microswitch is in contact with the knife group assembly; the first microswitch gives the controller a signal, and the controller controls the motor to rotate forward, and the motor drives the knife group assembly to move upward along the axial direction to the trigger member to trigger the second upper limit microswitch; the second upper limit microswitch gives the controller a signal, and the controller controls the motor to reverse, and the motor drives the knife group assembly to move downward along the axial direction to the trigger member to trigger the lower limit microswitch, and the lower limit microswitch gives the controller a signal, and the controller controls the motor to stop running.

[0074] Specifically, the first upper limit micro switch and the second upper limit micro switch are connected in series, and when either one of them is triggered, the controller controls the motor to reversely drive, thereby preventing accidental damage caused by the second upper limit micro switch being in a position where it does not contact the knife assembly;

[0075] The outer wall of the first cup assembly is provided with two first trigger parts, and the two first trigger parts can act on the first connecting rod assembly and the second upper limit connecting rod assembly; the outer wall of the second cup assembly is provided with two second trigger parts, and the two second trigger parts can act on the first connecting rod assembly and the second upper limit connecting rod assembly; and the axial height of the first trigger part is greater than the axial height of the second trigger part; then, after the first cup assembly is assembled to the main machine, the distance that the first connecting rod assembly and the second upper limit connecting rod assembly can be driven to move downward is greater than the distance that the second cup assembly can be driven to move downward after being assembled to the main machine;

[0076] The second upper limit connecting rod assembly comprises a second upper limit connecting rod capable of linear motion along the axial direction, and a connecting rod elastic member capable of giving the second upper limit connecting rod a tendency to always move away from the second upper limit micro switch along the axial direction;

[0077] The main machine is provided with a buckle plate for installing the first connecting rod assembly and the second upper limit connecting rod assembly, the first microswitch and the second upper limit microswitch are relatively arranged below the buckle plate, the first connecting rod assembly and the second upper limit connecting rod assembly are relatively arranged above the buckle plate, and the first connecting rod and the second upper limit connecting rod can pass through the buckle plate to trigger the first microswitch and the second upper limit microswitch respectively; the main machine is also provided with a mounting frame for installing the second upper limit microswitch, an axis portion is provided below the buckle plate, the mounting frame is rotatably connected to the axis portion, and a torsion spring is provided between the mounting frame and the axis portion, the torsion spring gives the mounting frame a force tending to move toward the direction approaching the knife group assembly; and the surface where the second upper limit connecting rod and the mounting frame contact is an inclined surface, which can realize the downward movement of the second upper limit connecting rod to drive the mounting frame to rotate in the direction away from the knife group assembly, and drive the second upper limit microswitch away from the knife group assembly;

[0078] After the first cup assembly is assembled to the main machine, the first trigger part will give a downward force to the second link upper limit link, so that the first link and the second link lower limit link move downward, and the second link upper limit link and the mounting bracket are tilted and matched, and the mounting bracket is driven to rotate around the shaft, driving the second upper limit micro switch away from the knife group assembly, so that the axial up and down movement of the knife group assembly will not trigger the second upper limit micro switch, but trigger the first upper limit micro switch, so that the rising height of the knife group assembly is matched with the height of the first cup assembly; and after the first cup assembly is removed from the main machine, the link elastic part will give an upward force to the second link upper limit link, so that the second link upper limit link moves up and resets; and after the second link upper limit link moves up and separates from the mounting bracket, the mounting bracket moves toward the direction close to the knife group assembly and resets under the action of the torsion spring;

[0079] After the second cup assembly is assembled to the main machine, the second trigger part will give a downward force to the second connecting rod upper limit link, so that the first connecting rod and the second upper limit link move downward. Since the height of the second trigger part is not enough to drive the second upper limit link to drive the mounting frame, the second upper limit micro switch is in a position to contact the trigger part of the knife group assembly; after the knife group assembly moves upward along the axial direction, the second upper limit micro switch will be triggered, so that the rising height of the knife group assembly is to match the height of the second cup assembly.
