What are the characteristics of the single tube precision screw valve glue supply series
source：www.numie.cn | Release time：2025年12月16日1. High precision and strong stability of adhesive supply: Its core adopts an eccentric spiral screw and stator structure, coupled with DC servo motor drive, which can achieve quantitative adhesive output by correctly controlling the number of screw rotations. Some models can achieve a dispensing volume of up to 0.0005ml, with an accuracy of ± 0.0002ml and a repeatability of over 99%. Even if the viscosity of the adhesive changes or contains small particles, it can ensure consistent dispensing volume every time, avoiding the problem of decreased product yield caused by uneven dispensing volume.
2. Wide range of fluid adaptability: Compared with the limitations of traditional dispensing equipment on fluid viscosity, this series has extremely strong adaptability and can handle low, medium, and high viscosity fluids in the range of 0-500000 CPS. Whether it is high viscosity fluid such as solder paste, heat dissipation paste, thermal conductive gel, or medium viscosity fluid such as silica gel, or special fluid with additives, UV glue, epoxy resin, etc., it can be transported smoothly, which solves the pain points of traditional equipment in handling high viscosity glue that is easy to break and is unstable.
3. Good anti drip and anti wire drawing effect: The equipment can achieve the suction function by controlling the motor to rotate forward and backward. When the glue supply is stopped, the screw rotates slightly in the opposite direction to instantly cut off the glue wire, and at the same time, the residual glue liquid at the suction valve port is sucked back, effectively avoiding the problems of wire drawing and dripping after glue dispensing. This feature can keep the workbench clean and prevent the glue from contaminating the product, ensuring the cleanliness of the dispensing process.
Easy maintenance and long service life: adopting modular design, the screw components can be quickly disassembled and assembled, without the need to remove the entire valve body from the equipment, and maintenance operations such as cleaning and replacing parts can be completed, greatly reducing maintenance workload. The core screw components are mostly made of superhard alloy or SUS304 titanium plated material, and the stator is made of corrosion-resistant FFKM material, which has strong wear resistance and corrosion resistance. It can not only adapt to fluids containing particles, but also extend the service life of the equipment and reduce long-term maintenance costs.
4. Flexible and efficient adaptation scenarios: This series of valve bodies has a compact structure and is lightweight, making it easy to install in different types of automated production lines. Some models can also operate in narrow gaps of 0.2mm. At the same time, by adjusting parameters such as motor speed and air pressure, the dispensing amount can be flexibly adjusted, and operations such as variable dispensing width and complex trajectory dispensing can also be achieved. Its efficient screw conveying mode can quickly complete the glue supply task without consuming compressed air. Compared with pneumatic valves, it can save 30% glue, improve production efficiency, and reduce consumable costs.
