The principle and material receiving method of spiral dispensing machine

Principle of spiral dispensing valve:
The screw dispensing valve is a new type of valve body that is composed of a rotor and stator that mesh with each other to form a regular geometric capacity body, which can be used for dispensing metering. The main working components are an eccentric screw and a fixed sleeve (rubber material). Due to the special geometric shape of these two components, separate sealed cavities are formed, and the medium is uniformly pushed and flows through the meshing of the rotor and stator. The internal flow rate is low, the volume remains unchanged, and the pressure is stable, so there will be no vortex or agitation. Mainly used in the high-precision fluid dispensing industry.
The spiral dispensing valve is suitable for high viscosity fluids such as solder paste dispensing, silicone, UV glue, flux, silver glue, etc.
Compared with conventional dispensing methods, spiral dispensing valves have the following main advantages:
1. Precise dispensing and accurate measurement
2. Not easily clogged, ensuring stable and reliable glue production, with unparalleled advantages compared to conventional glue valves. For high viscosity and high auxiliary slurry, such as copper powder slurry and nickel slurry, it can also easily produce glue.
3. There is a sealed cavity structure inside, ensuring accurate measurement while also adapting to colloids with multiple fillers or particles.
The specific feeding method of the spiral dispensing valve is as follows:
1. Matching glue cylinder: 5ml/10ml is used for silver paste gluing, and 30ml/50ml can be used for larger quantities of glue such as tin paste, red glue, black glue, and UV glue. 300ml glue cylinder can be selected.
2. Equipped with a pressure bucket and a pressure plate bucket, the rubber material is pressed out from the bottom through air pressure, and the discharge port is connected to a spiral dispensing valve to measure the rubber output. It is generally used for high viscosity or contact variants. For example: lubricating grease, nickel slurry, copper slurry, silicone ester, etc., use this combination to accurately measure and reduce waste.
