The specific embodiment
The utility model provides a kind of injecting type glue dispensing valve, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The embodiment of the utility model injecting type glue dispensing valve; As shown in Figure 1; Comprise cylinder 100, be communicated with said cylinder 100 striker 110, be arranged at striker 110 lower ends nozzle 120, advance adhesive dispenser 250 and inlet duct 260; Said nozzle 120 is arranged in the nozzle fixed cap 130, and the upper end of said striker is connected with piston 170 and spring 160, and said cylinder 100 upper ends are connected with last fixed cap 150; Saidly enter the both sides that adhesive dispenser 250 and inlet duct 260 are arranged at cylinder 100, be provided with between said striker 110 and the nozzle 120 one be used to reduce striker and nozzle wear packing ring 140.
Specifically; Said injecting type glue dispensing valve is to carry out a glue operation with certain air pressure propelling fluid through nozzle 120, be provided with between said striker 110 and the nozzle 120 one be used to reduce striker and nozzle wear packing ring 140, as shown in Figure 3; This packing ring 140 can adopt the rubber-like material; To have good use elasticity, this packing ring 140 generally can adopt O type packing ring, with better adaptive striker 110 and nozzle 120.This packing ring 140 can avoid the striker 110 of metal material and nozzle 120 to collide the wearing and tearing that cause repeatedly effectively, thereby significantly prolongs the service life of striker 110 and nozzle 120; In addition, this packing ring 140 also can effectively remedy the gap between striker 110 and the nozzle 120, has guaranteed good sealing property, and upwards string is moving and influence the normal operation of glue dispensing valve when having avoided glues in the nozzle 120 to reset along with striker 110.In addition, also can striker 110 and the tip below promptly, the bottom of nozzle 120 be set to the structure of arc, this structure has certain cushioning effect; Compare with turbination structure commonly used; Increased the contact zones of striker 110 and nozzle 120, thereby reduced element precision and assembly difficulty, made striker 110 and nozzle 120 under the situation that non-high accuracy cooperates; Two contact-making surfaces also can compensate mismatch error automatically; Realize good sealing effectiveness, also can eliminate the problem easy to wear that original turbination structure is brought in addition, thereby prolong the service life of equipment.
Further, said cylinder 100 can adopt external screw thread to be connected with last fixed cap 150, and is as shown in Figure 1; Cylinder 100 was connected with the accurate fine thread of last fixed cap 150 general employings in the past, and this connected mode is more shallow because of connecting, often the words of work; Be prone to cause wearing and tearing, influence the life-span, the utility model adopts external screw thread to be connected with last fixed cap 150 in cylinder 100; This connected mode connects darker, not easy to wear, and can satisfy the purpose of regulating calibration loop.Can adopt accurate fine thread to be connected between said in addition cylinder 100 and the nozzle fixed cap 130; What guarantee that nozzle fixed cap 130 can be stable is fixed on outside the cylinder 100, and certainly, cylinder 100 also can adopt external screw thread to be connected the service life with prolongation cylinder 100 and nozzle fixed cap 130 with nozzle fixed cap 130; In addition; The screens of spanner also can be set, to be used under the stuck situation of the screw thread between nozzle fixed cap and the cylinder, also can carrying out dismounting through spanner in the periphery of nozzle fixed cap 130; Thereby under the assurance fortuitous event, can carry out work through simple maintenance.
Further; Be provided with piston between said spring 160 and the piston 170 and hit pad 180; As shown in Figure 1, said spring 160 is used for the return of striker 110, and this piston hits pad 180 and can be used for hard contact the between buffer spring 160 and the piston 170; Can reduce the generation of piston 170 and spring 160 loose contact situation, thereby strengthen the stability of the utility model injecting type glue dispensing valve.
Further, also be provided with the temperature control system of heater and control heater in the periphery of nozzle fixed cap 130, heater and temperature control system thereof are used for the heating of glue, make glue have good mobility.Said advance adhesive dispenser 250 comprise glue inlet tube 190 and be connected with said glue inlet tube 190 advance glue adapter 200; As depicted in figs. 1 and 2; A said end that advances glue adapter 200 is connected with cylinder 100; Said inlet duct 260 comprises air inlet pipe 210 and the air inlet adapter 220 that is connected with said air inlet pipe 210, and an end of said air inlet adapter 220 is connected with cylinder 100, also can be used to control the break-make of air pressure at the solenoid directional control valve that an end of inlet duct 260 is furnished with a two-position three way.Calibration loop 240 and adjusting screw(rod) 230 also can be set above striker 110 in addition, be used for regulating exactly into glue amount.
The course of work of the utility model injecting type glue dispensing valve is following: enter into from glue inlet tube 190 in the cavity volume of nozzle 120 when air pressure promotes colloid, glue is preheating in nozzle 120 cavity volumes just, to strengthen the flowability of glue.When glue dispensing valve need not spray glue; The solenoid directional control valve of two-position three way is in the normally open of dead electricity; Do not have Pneumatic pipe cleaner to cross inlet duct 260 this moment, owing to there is not pressure to act on the piston 170, the sealing cone that piston 170 makes striker 110, nozzle 120 cooperatively interact under the pressure of spring 160 is closed; Glue can not be from 120 li outflows of nozzle, and glue dispensing valve does not spray glue.When glue dispensing valve need spray glue, the closure state that the solenoid directional control valve of two-position three way is in electricly, Pneumatic pipe cleaner were crossed inlet duct 260 and are got in the cylinder; Behind the pressure of thrust that acts on the piston 170 greater than spring 160, on beginning, moves in piston 170, and on rising to after the fixed cap 150; Piston 170 moves on just stopping, and in piston 170 uphill process, can drive striker 110 and rise synchronously; Sealing cone forms certain gap between striker 110 and the nozzle 120 at this moment, and glue just flow in the spray orifice of nozzle 120 through the space, and the solenoid directional control valve of two-position three way is in the normally open of dead electricity then; Air pressure breaks off; Striker 110 resets under the effect of spring 160 and cylinder 100 internal gas pressures fast, and striker 110 produces a kind of impulsive force at high speed in reseting procedure, thereby impels glue from the spray orifice of nozzle 120, to spray fast and go out.
In sum; The utility model injecting type glue dispensing valve since between striker and nozzle, be provided with one be used to reduce striker and nozzle wear packing ring; The wearing and tearing of effectively having avoided striker and nozzle repeated friction to cause; Thereby prolonged the service life of striker and nozzle, this packing ring has also effectively remedied the gap between striker and the nozzle, has guaranteed good sealing property.
Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims.
