Description
Technical field
The utility model relates to a kind of delicate metering valve, particularly relates to a kind of delicate metering valve, is used for improving accurate some glue accuracy.
Background technology
Point glue equipment is the equipment of a kind of bonding, perfusion that is used for product technology, coating, sealing, filling, drop, linear/arc/purposes such as circular gluing, metering valve then belongs to a vitals in the point glue equipment, ON/OFF control by valve can realize that convection current goes out colloid and controls.Existing metering valve mainly contains plunger type metering valve, striker formula metering valve and metering valve.The plunger type metering valve is to utilize the motion of plunger to realize the switch of valve, the metering valve of this structure, its plunger is provided with waney leading section, the end diameter that is plunger is bigger, termination medial segment diameter is less, and when the termination of plunger was engaged in the forward sealing portion of valve body, valve was in closed condition, do not communicate between charging hole and the discharge opening, sizing material can't flow out; When plunger travels forward and medial segment diameter less part in termination is matched with the forward sealing portion of valve body, because have the gap between the plunger of this moment and the forward sealing portion of valve body, valve is in open mode, therefore, be connected between charging hole and the discharge opening, sizing material flows out; When the past swivel motion of plunger, matched with the forward sealing portion of valve body in the bigger termination of diameter, valve closing so repeatedly, is realized the ON/OFF of glue valve.Because plunger needs back and forth movement, therefore, can produce wearing and tearing owing to rubbing mutually between the front and back ends sealing of plunger and valve body, cause these positions to seal, and then glue is leaked in generation.On the other hand, because during valve-off, plunger moves backward, sizing material can be pushed backward in the termination that diameter is bigger, makes sizing material spill and enter cylinder from the back-end sealing portion of valve body easily, and metering valve is damaged.It mainly is the effect of playing the open and close glue channel by striker bump striker seat for a striker formula metering valve, and striker and first piston are by the sealing of striker sealing gasket.Contain microparticle because of glue composition the inside, rub mutually between striker, striker seat and the glue microparticle three, after a period of time, striker damages easily.In addition, often put glue, then require striker in the endoporus of striker sealing gasket, to move back and forth, like this, often, can cause the endoporus wearing and tearing, it is big that the aperture becomes, and do not have sealing effectiveness, glue then can enter in the cylinder by endoporus, flows out from cylinder vent, and metering valve then damages.On the other hand, striker and striker sealing gasket are in zero basically and join the excessive or too small life-span that all can directly influence striker of processing dimension.Metering valve is to utilize barrier film to realize that the Z that opens of valve closes, when diaphragm seals during, valve closing in charging hole and discharge opening, and when barrier film leaves the position that is closed in charging hole and discharge opening, valve open.Since the head with first piston be directly to link together, therefore, following drawback is arranged: the one, a movable position is very thin, glue valve of every open and close, the head all do relative motion with first piston, of long duration after, a motive position ruptures easily; The 2nd, the direct and fluid slot bump of head, head is wearing and tearing easily; The 3rd, barrier film and valve head are one, and material is macromolecular material, because too thin, be difficult to injection moulding usually and process, but the car system of employing forms, and make difficulty of processing big, and the cost height.
Therefore, there is defective in prior art, needs to improve.
