The working principle of each component of the hot melt adhesive coating machine (4).

Automatic compensation control system: hot melt adhesive coating machine introduction, with output signal control solenoid valve, the compressed air controlled by the solenoid valve drives the work of the gun body to control the opening and closing of the glue. And output 0-10V DC voltage control inverter to drive the motor to rotate. The output voltage is proportional to the speed of the line being measured. Introduction of hot melt adhesive coating machine, which can adjust the glue level, breaking length and tracking voltage online. Check Devices for measuring the speed of production lines include proximity switches, rotary encoders, etc. Hot melt adhesives are collectively known in the industry room, in fact, there are many types of hot melt adhesives, including EVA, PA, PES, PUR, pressure sensitive adhesives and so on.
