Abstract
The utility model provides a plunger pump used for producing soft capsules. The plunger pump comprises a plunger rod and a plunger sleeve that are mutually matched. A holding space is formed between the plunger rod and the plunger sleeve and the plunger sleeve is provided with a liquid inlet and a liquid outlet which are communicated with the holding space. The plunger rod is provided with a gap, when the gap opens the liquid inlet with the rotation of the plunger rod, the plunger rod closes the liquid outlet, or when the plunger rod closes the liquid inlet, the gap opens the liquid outlet. With the linear reciprocating movement between the plunger rod and the plunger sleeve, the holding space periodically reaches a maximum volume value and a minimum volume value. The opening and closing control of the liquid inlet and the liquid outlet of the plunger pump is completely realized by the self structure of the plunger without adding a reversing structure. The circulation space of liquid medicine is relatively closed, thus greatly reducing the link of liquid medicine leakage and ensuring the accuracy and stability of loading capacity.
