Plastic emitting and suction collagen reason：
During plastic emitting, moulding piston 41 moves towards the direction of gum outlet 121, produces compression and forms pushing force, due to entering glue
In the presence of check valve 3, caused pushing force direction is identical with the elastic force direction for entering the back-moving spring 22 in glue check valve 3,
Valve element 21 is pressed against on valve port 23, now, the valve port 23 for entering glue check valve 3 is closed.And the glue in plastic emitting passage 12 is then
Moved to the direction of gum outlet 121, in moving process, glue promotes the valve element 21 on plastic emitting check valve 2, it is overcome plastic emitting list
Moved to the elastic force of the back-moving spring 22 of valve 2 to away from the direction of valve port 23, so that the valve port 23 of plastic emitting check valve 2 is beaten
Open, glue flows out from gum outlet 121.
When entering glue, moulding piston 41 moves to away from the direction of gum outlet 121, produces negative pressure and forms suction, due in plastic emitting
In the presence of check valve 2, caused suction direction is identical with the elastic force direction of the back-moving spring 22 in plastic emitting check valve 2, i.e.,
Valve element 21 is pressed against on valve port 23, now, the valve port 23 of plastic emitting check valve 2 is closed.And due to suction direction and glue feeding channel
The elastic force of back-moving spring 22 in 13 is in opposite direction, therefore that the elastic force of back-moving spring 22 can be overcome to drive is unidirectional into glue for suction
Valve element 21 on valve 3 moves to away from the direction of valve port 23, so that the valve port 23 for entering glue check valve 3 is opened, glue is from entering glue
Mouth 131 enters, and is pumped into plastic emitting passage 12.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in the scope of protection of the utility model by Patent Law.
