The course of work of the present embodiment glue dispensing valve is as follows：Glue loads packing element, using air pressure, glue is pressed into packing element and connect
In head, then the cavity volume by entering valve head enter glue transfer block, glue can be adjusted by glue amount vernier knob in this process
The gel quantity of cylinder；When glue dispensing valve is not required to glue spraying, magnetic valve is in the normally open of dead electricity, and no air pressure passes through entering on cylinder
Stomata enters cylinder, and now because no pressure upstream is acted on piston, piston can not move up, and thimble is under the pressure of the spring
Closed with the spray orifice of glue spraying head, colloid can not flow out in the spray orifice of glue spraying head, glue dispensing valve not glue spraying；When glue dispensing valve needs glue spraying
When, give magnetic valve one signal, piston of the magnetic valve in the closure state being powered, first drive cylinder up moves, as
After being more than the pressure of spring with the thrust on piston, piston moves up, and then drives thimble synchronously to move up between spray orifice
Certain gap is formed, at this moment glue can be flowed into spray orifice by gap, and then solenoid-driven piston moves downward, and driven
Thimble during impact, promotes glue spouting from the spray orifice of glue spraying head, in the process, spring also can be to work downwards
Plug applies pressure, piston and thimble is faster resetted, a kind of acceleration shock power is produced during resetting at, and accelerates
The dispensing speed of glue dispensing valve, the compaction degree of spring can be adjusted by stroke fine adjustment screw, and compaction degree is bigger, and piston is applied
Reset pressure it is bigger, piston reset speed is faster, so that dispensing speed is faster, highest dispensing speed can reach per second 200
The dispensing speed of point, drastically increases operating efficiency.
The size of injection glue amount need to such as be changed in the present embodiment, can be adjusted by following methods：The glue amount that first comes loose is prevented
Loosen the screw a little, change the gap between glue amount fine setting nut and stroke fine adjustment screw, i.e., when turning stroke adjustment clockwise, glue amount
The gap finely tuned between nut and stroke fine adjustment screw reduces, and makes regulating rod deeper into cylinder, so that the sky that piston moves up
Between reduce, the space between thimble and spray orifice also reduces therewith, now when in packing element promote glue pressure it is certain in the case of,
By the glue amount in space than being reduced before it in same time, the glue amount thus ejected can also reduce；Otherwise when counterclockwise
When turning glue amount fine setting nut, the glue amount ejected can increase；During adjusting herein, it can also pass through the glue on packing element joint
The gel quantity of vernier knob control packing element is measured, in the case of promoting glue pressure certain in packing element, the packing element gel quantity of control
It is bigger, it is bigger by the glue amount in space in same time, on the contrary the packing element gel quantity of control is smaller, passes through in same time
The glue amount in space is smaller；The gel quantity of glue spraying head can more accurately be controlled by finely tuning nut and the cooperation of glue amount vernier knob by glue amount,
Gel quantity number can determine to spray the size of glue point, so as to improve precision for dispensing glue, reduce defective products rate and reduce being produced into
This.
The technical scheme provided above the utility model embodiment is described in detail, used herein specifically
Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in embodiment and application, in summary, this specification content should not be construed as
To limitation of the present utility model.
