902, it is then fixed in lower valve body 700 with locking nut 903 again, then respectively in the first inlet suction port 400, the second air inlet connecting
First 600 and corresponding pressure pipeline is connected into cemented joint 800.When the first inlet suction port 400 supplies, and the second inlet suction port 600
When not supplying, gas enters in the second upper cavity 121 from the first inlet suction port 400, thus compression retracteding position spring 300, so that
Piston 200 moves upwards, to drive needle 201 to move upwards, so that needle 201 is detached from gum outlet, at this time into cemented joint 800
Interior colloid, which just passes through third cavity 702 and is flowed on a plastic pin 902, carries out dispensing, when needing to adjust gel quantity, Ke Yitong
It crosses and manually adjusts gauge microsize 10 to adjust gel quantity, meanwhile, also it can also make to bring about the desired sensation by supplying in the second inlet suction port 600
Body enters the first upper cavity 111 from the second inlet suction port 600, in this way since the pressure of gas acts on, so that piston 200 is downward
Movement, the distance between needle 201 and gum outlet become smaller, to reduce its gel quantity.When needing to suspend dispensing, the first air inlet
Connector 400 stops power supply, and return spring 300 releases energy elongation, drives piston 200 to move downward, so that needle 201 is withstood out
Jiao Kou quickly stops plastic emitting, ensure that accuracy for dispensing glue.
In conclusion the invention discloses a kind of ejector pin type glue dispensing valve, the glue dispensing valve can arbitrarily with charging pump or storing
Pressure pot link uses, and can assemble the operation simultaneously of several glue dispensing valves simultaneously, save the production time, reduce consumption, compressed air is
Power, fluid seal structure reduce the frequency of replacement sealing element, and maintenance is quick, meanwhile, it is capable to replace a variety of different dispensings
Needle, gluing is accurate, prolongs its service life.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations all should belong to the guarantor of appended claims of the present invention
Protect range.
