Filling machine

Abstract

The invention discloses a filling machine. The filling machine comprises a filling station located on a machine frame. The filling station comprises a plunger pump, a filling device and a pneumatic corner valve, wherein a pump body of the plunger pump is fixed to a rotary base plate, and a piston rod of the plunger pump is connected with a first lifting device; a filling nozzle of the filling device is aligned with a bottle opening of a preparation bottle; the pneumatic corner valve comprises an inlet and two outlets, the inlet is communicated with a high-position liquid storage tank, one outlet is communicated with an opening in the pump body of the plunger pump, and the other outlet is communicated with the filling nozzle. Liquid medicine is sucked in and pressed out through the plunger pump, the requirement for the preparation bottle is not strict, and the filling machine can be adaptive to most preparation bottles; the quantity of liquid medicine sucked in and discharged by the plunger pump can be accurately controlled by adjusting the expansion amount of the piston rod, so that the filling quantity is accurately controlled. By controlling the lifting frequency of the first lifting device, the first lifting device can be matched with other equipment on a production line, the production speed is guaranteed, and production efficiency is improved. Moreover, the filling machine is simple in structure, convenient to disassemble, wash and maintain, and low in manufacturing and using cost.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a filling machine. Background technique [0002] At present, the preparation liquid is generally filled into the preparation bottle through the filling machine, and after the filling is completed, it enters the next station for the plugging process. [0003] In the prior art, the more commonly used filling machines generally include linear filling, rotary reciprocating tracking filling or rotary self-flowing time pressure control filling according to the filling method. For some preparations, such as syrup preparations, when filling, the linear filling speed is relatively slow and the requirements for the preparation bottle itself are relatively standard, especially the mouth of the preparation bottle, which has poor applicability; the rotary reciprocating tracking filling Vibration is large, dripping is easy to occur, resulting in noise and waste; self-flowing time-pr...
