Abstract
The utility model relates to a displacement piston pump for a pneumatic unidirectional valve, which relates to a material feeding system specially used for matching with a packaging machine. The utility model is composed of a main pump, a middle cylinder body, a sealing sleeve, an oil cup, a lubricating device, a material feeding device, a material discharging device, an oil injecting device, an oil receiving device and a quantitative system, wherein the sealing sleeve, the oil cup, the lubricating device, the material feeding device, the material discharging device, the oil injecting device and the oil receiving device are arranged on the middle cylinder body. The main pump body is respectively provided with an air inlet pipe and an air exhaust pipe which are connected with a reversing solenoid valve. The utility model adopts the compressed air as motive power to push the cylinder to complete reciprocating movement. A piston rod of a main cylinder drives a material pushing plunger to complete the reciprocating action of pushing and sucking materials. Two unidirectional valves are used for complete the conversion of material sucking and material pushing, so intermittent material feeding can be realized. The utility model can realize on-line adjustment without stop, and the adjusting degree is accurate. Therefore, the utility model has the advantages of high precision of the material injection, rapid adjustment, simpleness and reliability. The precision can reach +/-0.15 ml in the range of 30 ml.
