Description
Technical field
This utility model relates to glue dispensing valve, especially a kind of negative pressure feedback resorption ejector pin type glue dispensing valve.
Background technology
Glue dispensing valve is most important work execution unit on point gum machine.Point gum machine is a kind of to be controlled by glue dispensing valve convection cell, and by fluid drop,
It is coated on the automatic machinery of product surface or interiors of products.Along with the development of technology, point gum machine is widely used in electronic manufacturing industry, industry
Electrically, photovoltaic, architectural engineering etc., market application is the most universal.Equipment has manual, semi-automatic and full-automatic at present.Automatization's journey
Spend more and more higher.
The application of point gum machine is enriched constantly and develops, and glue dispensing valve it is also proposed various forms of requirement.Existing point in some glue industry market at present
Glue valve style more than 30 is planted.Contact and contactless can be divided into by plastic emitting mode glue dispensing valve.Contactless glue dispensing valve is the most just to have grown up
New technique, similar inkjet printing principle, there is speed fast, the advantage that glue point is little, but technology is not the most the most ripe, very sensitive to the viscosity of glue；
And conventional contact glue dispensing valve because it is simple and reliable for structure, stable performance, applied widely, length in service life and be used widely.Common are:
Ejector pin type glue dispensing valve, plunger type glue dispensing valve, diaphragm type dispensing valve, AB biliquid glue dispensing valve, the most rotary glue dispensing valve etc..
The most popular resorption ejector pin type glue dispensing valve, glue enters from top to down, and when closed, movable valve is quickly lifted up valve,
A negative pressure can be produced at valve chamber inner chamber, in time the sizing material of " pulling " downward water clock, thus realize moment and break glue, preferably solve plastic emitting time delay
With wire drawing weeping.But during valve fast lifting, now glue has downward movement velocity, negative pressure occurs at valve, just produces air
Bubble or vacuum packet；And valve moves downward during common ejector pin type glue dispensing valve closedown, not having resorption function, disconnected colloidality can be slightly worse, pushes up during valve to be opened
Pin fast lifting, glue is moved into from top to bottom in glue valve body, owing to the glue direction of motion is contrary with thimble opening direction, opens moment at needle-valve
Top there will be negative pressure of vacuum equally, the most also can produce air bubble or vacuum packet.
Summary of the invention

Beneficial effect: this utility model enters glue mode under by the enterprising glue of change being, increases collection chamber and negative pressure feedback room, the plastic emitting of Novel adhesive dispensing valve
Seriality and moment colloidality of breaking can be significantly improved.It is in particular in the following aspects:
1. controlled valve opening size by gauge microsize, can precise fine-adjustment gel quantity, in the case of glue quality and operating pressure are stable, it can be ensured that
Go out accuracy and the seriality of flow adhesive；
2. glue is the most actively to enter valve, flow direction and valve opening direction one to, all move upward, be not likely to produce true
Empty；
3. set up collection chamber, can collect owing to pipeline air exhaust water is clean when starting working, or remaining bubble in glue and work produce
Gas；Set up negative pressure chamber, elastic diaphragm be connected with collection chamber, and with piston upper chamber pipeline communication, formed negative pressure chamber.In the descending closedown of needle-valve
Time, chamber, squeezing valve indoor, now on piston, indoor cavity pressure can drastically decline simultaneously, by pipeline negative pressure is delivered to negative pressure chamber, and make elastic every
Film deforms, and causes collection chamber volume to synchronize to expand, and collection chamber internal volume extensive magnitude is greater than that needle-valve is descending causes valve chamber smaller volume amount, can be true
Protecting the pressure moment of valve chamber inner chamber when needle-valve is closed reduces, and produces, to going out sebific duct, glue effect of inhaling, thus realizes moment and break glue；
4. due to the existence of collection chamber, during continuous plastic emitting, the effect of steady operation pressure can be played, make plastic emitting more steady, coherent；
5. valve is normally closed type, prevents hang-up and water clock；
6. needle-valve end uses spherical structure, has automatic centering, and the speed closed and open is more shorter than traditional cone structure required time, and control glue is more
Accurately.
