The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, injecting type glue dispensing valve of the present utility model, comprise nozzle 2, striker 3, cylinder 4, be furnished with into glue connects and sells 13 in the cylinder 4 and the centre of nozzle 2, be provided with the nozzle fixed cap 1 that is used for fixing nozzle 2 and striker 3 in the lower end of cylinder 4, cylinder 4 is connected locking with helicitic texture with nozzle fixed cap 1, and piston 5 places the upper end of striker 3, locks with helicitic texture with lock piston jack panel 6 between it.Between return spring 8 and piston 5, be lined with piston hit the pad 7, stroke adjustment 9 push down return spring 8 and with helicitic texture be connected at cylinder 4.Stud with stroke corrector loop 10 in the lower end of stroke adjustment 9, be furnished with into glue adapter 12 respectively in the left and right sides of cylinder 4, air inlet adapter 15 connects locking with helicitic texture.
The utility model cylinder 4 and nozzle fixed cap 1 since adopt be accurate fine thread structure carry out each other the location be connected, because accurate fine thread structure self has self-locking and locking effect, therefore cylinder 4 is difficult for getting loose with nozzle fixed cap 1 after locking.The outer annular knurl structure that is with at nozzle fixed cap 1, in the assembling process, frictional resistance between hand and the mouth fixed cap 1 increases, be difficult for sliding hand, therefore do not need to use again any auxiliary assembly tool, merely just can be cylinder 4 and 1 locking of nozzle fixed cap with hand, clear Xian is simple and convenient for assembling, dismounting, the efficient height.
As shown in Figure 3 and Figure 4, is furnished with the heating that heater and temperature control system thereof are used for colloid in the utility model in the periphery of nozzle fixed cap 1.Are furnished with one 2 the 3 ventilation break-makes of solenoid directional control valve at an end of air inlet pipe 14 in order to control air pressure.Is furnished with barrel so that the splendid attire colloid externally passes to air pressure at barrel colloid is flowed at an end of glue inlet tube 11.
In the utility model the glue for preparing in proportion (the glue brand be power still, A glue model is EB400A, B glue model is EB400B, the phosphor powder brand is huge, model is BG-20, the fluorescent powder particle diameter is 0.01mm.Mixed proportion is: A glue: B glue: phosphor powder=1: 0.9: 0.5, its sticking 1700cps. that is scheduling to after glue mixes) stir and pour in the barrel afterwards, and pass to air pressure.
The injection diameter of the utility model nozzle 2 is between 0.1mm～1mm.In an embodiment of the present utility model, nozzle 2 injection diameters are 0.18mm, and the air pressure that flows in order to the control colloid is 0.35MPa, is 0.6MPa in order to control piston 5 reciprocating air pressure.
The course of work of the utility model injecting type glue dispensing valve is as follows: when certain air pressure promote colloid from glue inlet tube 11, enter in the cavity volume of nozzle 2 preheating in cavity volume of colloid this moment advance glue adapter 12, advance glue connecting pin 13.When glue dispensing valve need not spray glue, 23 logical solenoid directional control valves are in the normally open of dead electricity, there is not Pneumatic pipe cleaner to cross air inlet pipe 14 and air inlet adapter 15, this moment is not owing to there is pressure to act on the piston 5, piston 5 can not on move, striker 3 under the pressure of return spring 8 with the nozzle closure, colloid can not flow out in the spray orifice of nozzle, glue dispensing valve does not spray glue.When glue dispensing valve need spray glue, the closure state that 23 logical solenoid directional control valves are in electricly, Pneumatic pipe cleaner is crossed the cavity volume that air inlet pipe 14 and air inlet adapter 15 enter cylinder 4, behind the pressure of thrust that acts on the piston 5 greater than return spring 8, move on the piston 5, move synchronously thereby drive striker 3, form certain space between striker 3 and the nozzle 2 this moment, and colloid flow in the spray orifice of nozzle 2 by the gap.This moment is when advancing the normally open that 23 logical solenoid directional control valves are in dead electricity, air pressure disconnects, striker 3 resets under the pressure effect of return spring 8 fast, produces a kind of acceleration shock power during the course resetting, thereby impels colloid spouting from the spray orifice of nozzle 2.
Change the size of spraying glue point as need in the utility model, can be by regulating: change stroke adjustment 9 and hit the gap of filling up between the piston 7 with following method, promptly when turning stroke adjustment 9 clockwise, hit the pad 7 and stroke adjustment 9 between or the gap reduce, thereby the space of moving on the piston 5 dwindles, space between striker 3 and the nozzle 2 also reduces thereupon, this moment is when promoting under the certain situation of colloid pressure, the glue amount by the space in the identical time compare before reduce, the glue point that ejects thus also reduces.Otherwise when turning stroke adjustment 9 counterclockwise, the glue point that ejects can increase.
The Pneumatic controller of injecting type glue dispensing valve periphery of the present utility model, can adopt the control mode of conventional baric systerm, the compressed air that uses needs through little mist separator wherein moisture content, oil stain filtration with separate, to guarantee compressed-air actuated quality, improve the service life of pneumatic element and injecting type glue dispensing valve.Aspect the type selecting of 23 logical solenoid directional control valves, the reflection time of solenoid directional control valve should lack, and it is fast that commutating frequency is wanted, and the Cv value of solenoid directional control valve will reach more than 0.2, so that adapt to the requirement that the injecting type glue dispensing valve sprays glue fast.
