Intelligent miniature metering screw valve of special dispensing and conveying equipment

Abstract

The invention discloses an intelligent miniature metering screw valve of special dispensing and conveying equipment, and relates to the technical field of liquid quantitative conveying. The intelligent miniature metering screw valve of the special dispensing and conveying equipment aims at solving the problems that an existing liquid outlet needle is rotationally installed through threads, threadsare abraded after being replaced and used for a long time, the connection tightness is caused to be affected, thereby the glue soluting conveying accuracy is caused to be reduced, a needle head installed in a threaded mode is short in service life and the like, the following solution is provided, the intelligent miniature metering screw valve of the special dispensing and conveying equipment comprises a brushless motor and a motor sleeve, wherein the brushless motor is fixedly installed on the inner wall of the top of the motor sleeve, the output end of the brushless motor is fixedly connected with a coupler, a driving shaft is arranged below the coupler, a connecting rod is arranged at the bottom of the driving shaft, and the bottom of the connecting rod is fixedly connected with a screwrotor. The intelligent miniature metering screw valve of the special dispensing and conveying equipment is simple and novel in structure, small in size, high in conveying precision, the needle head can be conveniently installed and replaced, high in connection stability, capable of improving discharging stability and prolonging the service life of the needle head and suitable for popularization.

Description

technical field

[0001] The invention relates to the technical field of liquid quantitative delivery, in particular to an intelligent micro metering screw valve of special equipment for dispensing and delivery. Background technique

[0002] The screw valve uses the rotation of the screw rotor to suck and discharge liquid. Multiple sealing spaces are formed between the screw rotor and the rubber stator. As the screw rotor and the stator rotate and mesh, these sealing spaces are continuously formed at the suction end of the pump, and the liquid in the suction chamber is sealed in it, and at the same time along the screw rotor axis Continuously moving to the discharge end, the liquid in the closed space will be continuously discharged, thus completing the liquid delivery process. The intelligent micro-metering screw valve has the advantages of small size, light weight, high precision, stable flow, no pulsation, fast back-suction response, and no wire drawing. Replacing the use...
