Problems solved by technology

The existing screw valve is generally composed of a motor, a motor seat, a coupling, a screw, a stator, and a glue outlet. However, when the motor of the existing screw valve rotates, there is no guarantee for the coaxiality between the screw and the valve body, so that the outlet of the entire screw valve cannot be guaranteed. Glue precision

Embodiment Construction

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] See Figure 1-9 , the high-precision screw valve of the present invention includes a driving device a, an anti-movement mechanism 5, an integrated rotor 1, a valve body seat b, a valve body 2, a glue discharging device c and a feeding device d, and the driving device a is used for feeding The integrated rotor 1 provides power, and the anti-movement mechanism 5 is used to transitionally connect the driving device a and the integrated rotor 1. The anti-movement mechanism 5 drives the integrated rotor 1 to rotate in the valve body 2, and the integrated rotor 1 is use...

Abstract

The invention discloses a high-precision screw valve, which comprises an integral rotor and a valve inner cavity and a screw inner cavity coaxially arranged on the valve body. The screw rod of the rotor is equipped with a coaxial rotating bearing with the cavity of the screw rod, and the integrated rotor is directly assembled on the valve body through the rotating bearing. The high-precision screw valve ensures the installation coaxiality between the screw and the screw inner cavity by matching and installing the rotating bearing in the valve inner cavity, and correspondingly ensures the installation clearance between the screw and the screw inner cavity, improving Assembly accuracy, and thus higher dispensing accuracy.

Description

technical field [0001] The invention relates to the technical field of screw valves, in particular to a high-precision screw valve. Background technique [0002] With the gradual maturity of automatic dispensing technology, the dispensing process has higher and higher requirements for dispensing accuracy, especially for the dispensing process of high-viscosity fluids and fluids with tiny solid particles. Screw dispensing for such fluids Valve accuracy requirements are becoming more and more stringent. The existing screw valve is generally composed of a motor, a motor seat, a coupling, a screw, a stator, and a glue outlet. However, when the motor of the existing screw valve rotates, there is no guarantee for the coaxiality between the screw and the valve body, so that the outlet of the entire screw valve cannot be guaranteed. glue precision. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior...
