[0006] Preferably, the base is connected to the worktable and the frame by welding, and the frame is connected to the pressing device by screws.
[0007] Preferably, the workbench includes a tabletop, with a pressing groove on one side of the top of the tabletop and a filter plate on the other side of the top of the tabletop.

[0009] Preferably, the electric actuator and the push plate are connected by screws, one end of the push plate is arc-shaped, and the arc of the actuator is consistent with the outer arc of the barrier ring.
[0010] Preferably, the pressing device includes a control motor, the control motor is equipped with a control system and a pressure sensor, the bottom of the control motor is equipped with a pressure rod, the bottom of the pressure rod is equipped with a punch, the bottom of the pressing device is equipped with a pressing groove, and the diameter of the punch is the same as the diameter of the pressing groove.
[0011] Preferably, the top of the collection box is open, a handle is provided on one side of the collection box, and a slot is provided on one side of the workbench, with the collection box disposed inside the slot.
[0012] Beneficial effects
[0013] This invention employs a pressing device, which consists of an electric pressing rod, a pressure sensor, and a control system. The electric pressing rod serves as the power source for applying pressure, and its stroke and thrust can be precisely controlled by the control system. The pressure sensor monitors the pressure value during the pressing process in real time and feeds the signal back to the control system, forming a closed-loop control system to achieve precise pressure adjustment. When pressure needs to be increased, the control system drives the electric pressing rod to extend, thereby increasing the pressure. When the pressure reaches the preset value, the electric pressing rod stops moving.
[0014] In this invention, a pusher plate and a filter plate are used. After pressing, the second motor causes the push rod to push out the tablets, and the first motor causes the electric push rod to move, so that the pusher plate pushes the barrier ring, the tablets inside, and the extruded powder to the filter plate. The powder and tablets are guided into the filter plate through the inclined guide surface, and the medicine is suspended on the filter plate, while the powder enters the collection box at the bottom through the filter plate. This facilitates the collection and reuse of the powder. Attached Figure Description
