Abstract

The invention provides a spot gluing apparatus. The glue valve can control the velocity and adjust the flow rate. The glue valve comprises a hydraulic pressure needle valve device to control the flow rate of glue material and an air pressure piston device to control the spot gluing velocity. The needle valve device and the piston device combine appropriately to carry out the up and down reciprocal movement. The needle valve device is changeable. The flow rate of glue material in the hollow flow path of needle valve can be controlled by using at least one throttle contour of needle valve device when the needle valve device opens or closes in the air pressure piston device. The adjusting screw can control at least one switching velocity for needle valve device.
