Abstract: A glue dispenser dispensing switch includes a switching device main body, a needle holding base, a wear-resistant plate, and a rotating device. The switching device main body is equipped with a double liquid inlet, the needle holding base is equipped with a mixed glue outlet, the wear-resistant plate is installed between the switching device main body and the needle holding base, and the wear-resistant plate is equipped with a wear-resistant plate opening. The rotating device is utilized to rotate the needle holding base or the wear-resistant plate. A mixed double-liquid glue passes through the double liquid inlet, the wear-resistant plate opening and the glue outlet to dispense a mixed glue while the double liquid inlet, the wear-resistant plate opening and the glue outlet are overlapped. In addition, a double liquid dispensing equipment is also disclosed herein.

Abstract: A glue dispensing device comprises a base, a pressure control unit, a quantitative glue supply unit and a glue dispensing needle. The base comprises a pressure control chamber and a glue tube body, the pressure control chamber is located inside the base, the glue tube body extends from one end of the base to the other end, and the glue tube body penetrates the pressure control chamber. The pressure control unit is coupled to the pressure control chamber. The quantitative glue supply unit is disposed at one end of the base body and is coupled to the glue tube body. The glue dispensing needle is disposed at the other end of the base and is coupled to the glue tube body. The glue dispensing device uses the pressure change of the pressure control chamber to deform the glue tube body, thereby achieving quantitative glue dispensing effect with accuracy and stability. In addition, a glue dispensing method is also disclosed.
