The core principle of single tube precision screw valve (single component) is volumetric metering+screw stator sealing chamber pushing+servo closed-loop control. It is driven by a motor to rotate the screw, and the glue is squeezed out of the nozzle in a "quantitative, constant speed, and pulsation free" manner. It stops when stopped and reverses to suck back and prevent dripping and leakage.

In the packaging industry, the core of servo glue coating line is high-precision glue coating+automated connection+glue saving and efficiency improvement. It is mainly used in color boxes/gift boxes, cardboard boxes/corrugated boxes, paper plastic composites, labels/films, and sealing/sealing.

The maintenance core of the automatic gluing line for packaging boxes is to prevent blockage, leakage, lubrication, and accuracy. It is carried out in a graded manner of "daily → weekly → monthly → quarterly/annual", which can significantly reduce failures, extend lifespan, and ensure stable gluing quality.

The glue supply system (including dispensing/filling/coating) is the core process equipment of the entire electronic manufacturing process. By correctly controlling the flow rate, pressure, path, and temperature of the glue, it achieves functions such as bonding, packaging, sealing, thermal conductivity, waterproofing, and insulation of electronic components. It deeply covers sub fields such as se
