Description
Technical field
The utility model relates to a kind of striker valve, particularly relates to a kind of striker 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, the striker 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 striker valve mainly contains plunger type striker valve, striker formula striker valve and striker valve.Plunger type striker valve is to utilize the motion of plunger to realize the switch of valve, the striker 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 the striker 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 striker valve, and striker and 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 the striker 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.The striker 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.Because diaphragm seal valve head and piston are directly to link together, and therefore, following drawback are arranged: the one, diaphragm seal valve head movable part position is very thin, glue valve of every open and close, the diaphragm seal valve head all does relative motion with piston, of long duration after, diaphragm seal valve head motive position ruptures easily; The 2nd, the direct and fluid slot bump of diaphragm seal valve head, the diaphragm seal valve head weares and teares 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.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of striker valve is provided, and has the processing and fabricating of being easy to, and cost of manufacture is low, long service life, the characteristics that volume is little.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of striker valve, comprise a upper valve body, valve body once, described upper valve body is arranged on the described top of valve body down, the two connects by jockey, one driving mechanism is set in described upper valve body, described driving mechanism, comprise cylinder body, piston, the cylinder body bottom is connected with the top of cutting agency, and piston is movably arranged in the cylinder body, piston tip connects a spring, spring withstands between cylinder body inside top and the piston tip, is provided with cavity in the middle of the bottom of cylinder body, is used for ejector ram and moves upward, the sidepiece of cylinder body is provided with at least one air admission hole, and air admission hole is connected with the cavity of cylinder body; In the valve body blanking mechanism is set under described, described cutting agency comprises a striker, one glue feeding opening, one nozzle, a fluid bore, the upper end of described striker closely links to each other with the piston lower end, and the lower end of described striker and has nozzle and closely cooperates, and between described striker and the described cavity sealing device is set at least, the lower surface of nozzle abuts in the top of valve body and is covered in described fluid bore and plastic hole, and glue feeding opening is connected with fluid bore.
Described a kind of striker valve, wherein, hold-down nut of the outer setting of described nozzle.
Described a kind of striker valve, wherein, between described striker and the air cavity, described piston and and cylinder body between, a Y-shaped ring is set respectively at least.
