Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 1 and Fig. 2, a kind of minitype pneumatic glue dispensing valve for automatic welding device of the present embodiment, including sleeve
10, suction nozzle 20, piston 30, spring 40, into glue mouth 50 and go out needle head 60, the sleeve 10 includes air inlet successively from left to right
Portion 11, cylinder body 12, into glue portion 13 and storage glue portion 14；Wherein, the suction nozzle 20 is connected to the intake section 11, described into glue
Mouth 50 be connected to it is described into glue portion 13, it is described go out needle head 60 be connected to the storage glue portion 14, the piston 30 and spring 40 are placed in institute
It states in cylinder body 12, the spring 40 is sleeved on the piston 30, the movement for limiting piston 30, and is provided back to piston 30
The power of bullet.
Wherein, suction nozzle 20 squeezes into glue portion 13 and storage glue for providing initial driving force, piston under gas pressure effect
Colloid in portion 14 makes colloid pass through and the output of needle head 60.When there is gas pressure effect, piston 30 is pressed into from cylinder body 12
Into glue portion 13, glue portion 14 will be stored up into the colloid indentation in glue portion 13, further by going out 60 plastic emitting of needle head, at this point, spring 40
