The single tube precision screw valve belongs to the volumetric single component glue supply valve body, which relies on servo driven screw stator engagement to form a closed cavity for conveying glue. Compared with time pressure dispensing valves and plunger valves, it has outstanding advantages in quantitative stability, fluid compatibility, process adaptation, installation and maintenance.

The entire production line is divided into six modules: glue supply metering system, vacuum defoaming chamber, conveying and transmission mechanism, heating and curing tunnel, vacuum pump system, and electrical control system. At the same time, it distinguishes between "daily inspection per shift" and "periodic maintenance", with risk warnings attached.

1、 Core advantages of measurement and proportioning Volumetric measurement, accuracy not affected by glue supply pressure or glue viscosity Single screw outputs a fixed volume per revolution; The adhesive output is only related to the rotation angle/speed of the motor. The fluctuation of upstream material bucket pressure, the increase and thinning of glue temperature, and the settlin

First, clarify the typical process flow of the equipment (turntable/straight line multi station): Loading → visual positioning → dispensing (fixing/reinforcing/sealing/soldering) → curing/preheating → soldering (laser soldering/constant temperature soldering iron soldering) → AOI visual inspection (adhesive path+solder joint) → NG sorting → good product unloading
