Reciprocating glue dispenser dispensing switch

Abstract

A reciprocating glue dispenser dispensing switch includes a switching device main body, a needle holding base, a sliding wear-resistant plate, and a driving 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 sliding wear-resistant plate is installed between the switching device main body and the needle holding base, and the sliding wear-resistant plate is equipped with a sliding wear-resistant plate opening. The driving device is utilized to move the sliding wear-resistant plate. A mixed double-liquid glue passes through the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet to dispense a mixed double-liquid glue while the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet are overlapped.

What is claimed is: 
     
         1 . A reciprocating glue dispenser dispensing switch, comprising:
 a switching device main body having a double liquid inlet;   a needle holding base having a mixed glue outlet;   a sliding wear-resistant plate equipped between the switching device main body and the needle holding base, the sliding wear-resistant plate having a sliding wear-resistant plate opening; and   a driving device moving the sliding wear-resistant plate, wherein a mixed double-liquid glue passes through the double liquid inlet, the sliding wear-resistant plate opening and the mixed glue outlet to dispense the mixed double-liquid glue when the double liquid inlet, the mixed glue outlet and the sliding wear-resistant plate opening are overlapped.   
     
     
         2 . The reciprocating glue dispenser dispensing switch of  claim 1 , further comprising a needle fixed to the mixed glue outlet of the needle holding base. 
     
     
         3 . The reciprocating glue dispenser dispensing switch of  claim 1 , further comprising a driving rod connecting to the driving device and the sliding wear-resistant plate. 
     
     
         4 . The reciprocating glue dispenser dispensing switch of  claim 1 , further comprising a chute formed between the switching device main body and the needle holding base. 
     
     
         5 . The reciprocating glue dispenser dispensing switch of  claim 1 , wherein the sliding wear-resistant plate comprises a polytetrafluoroethylene sliding wear-resistant plate. 
     
     
         6 . The reciprocating glue dispenser dispensing switch of  claim 1 , wherein the driving device comprises a pneumatic cylinder. 
     
     
         7 . The reciprocating glue dispenser dispensing switch of  claim 1 , wherein the driving device comprises a hydraulic cylinder.
