Industrial Glue Applicators works:
Compressed air is sent into the plastic bottle, and the glue is pressed into the feeding tube connected to the piston chamber. When the piston is in the upstroke, the piston chamber is filled with glue. When the piston pushes the glue dropping the needle down, The glue is pushed out of the needle. The amount of glue dropped is determined by the distance of the piston undershooting, which can be adjusted manually or automatically controlled in software.
High speed, low sensitivity to adhesive viscosity.
It can increase the dispensing speed, improve the dispensing environment, and improve the quality of dispensing.
