The pneumatic injection glue dispensing valve of the utility model embodiment is described in detail with reference to the accompanying drawings.
Referring to figs. 1 to 4, according to pneumatic injection glue dispensing valve provided by the embodiment of the utility model, including valve body 10,
Injector head 20, striker 30 and regulating mechanism 40.
Specifically, injector head 20 is set to the bottom of the valve body 10.Striker 30 is slidably arranged in institute along the vertical direction
It states on valve body 10 and the injector head 20 is protruded into its lower end.That is, striker 30 can move along the vertical direction, wherein to
It can be hit inside injector head 20 when lower movement, so that the glue in injector head 20 sprays.
Regulating mechanism 40 includes pedestal 401, screw rod 403, thread bush 402 and elastic component 404, and the pedestal 401 is installed on
On the valve body 10, the pedestal 401 has through-hole 4011 perforative along the vertical direction, and the thread bush 402 is arranged in described
It is locked in through-hole 4011 and by locking member 41 with the pedestal 401.
403 screw thread of screw rod is socketed in the thread bush 402, and the upper end of the screw rod 403 is worn from the thread bush 402
Out, the lower end of the screw rod 403 and the upper end of the striker 30 have preset distance, to limit the stroke of the striker 30.
Elastic component 404 is set between the valve body 10 and pedestal 401, and the upper end of the elastic component 404 and the spiral shell
The lower end of line set 402 offsets, and the lower end of the elastic component 404 and the upper end of the striker 30 offset.
That is, thread bush 402 is threadedly coupled with screw rod 403, and thread bush 402 is by locking member 41 and base
Seat 401 is fixed, and locking member 41 can carry out elastic adjusting, and then thread bush 402 and pedestal 401 is fixed or release solid
It is fixed, when releasing fixed, thread bush 402 can be rotated.
Since the lower end of thread bush 402 and the upper end of elastic component 404 offset, so, it is transported by adjusting about 402 thread bush
Dynamic, then the initial length of adjustable elastic component 404, that is to say, which can be used for the initial of elastic component 404
What length was adjusted.Specifically, unclamping thread bush 402 by locking member 41, then by thread bush 402 around direction one by one
Rotation (counterclockwise), then thread bush 402 moves downward, and the lower end of thread bush 402 compresses downwards elastic component 404, so that spring
Initial length shorten;And by thread bush 402 around opposite direction rotation (clockwise), then thread bush 402 moves upwards, elastic component
404 gradually discharge, so that the initial length of spring extends.
Due to having preset distance between the lower end of screw rod 403 and the upper end of striker 30, the stroke of striker 30 can be limited
So being moved up and down by adjusting screw rod 403, then the stroke of adjustable striker 30, that is to say, which can be used for
The stroke of striker 30 is adjusted.Specifically, then screw rod 403 is transported downwards by screw rod 403 around the rotation (clockwise) of a direction
Dynamic, the distance between 403 lower end of screw rod and 30 upper end of striker reduce, at this point, the distance that striker 30 moves up and down reduces, play and subtract
The purpose of small stroke;And by screw rod 403 around opposite direction it is (counterclockwise) rotation, then screw rod 403 moves upwards, 403 lower end of screw rod with
The distance between 30 upper end of striker increases, at this point, the distance that striker 30 moves up and down increases, plays the purpose for increasing stroke.
According to pneumatic injection glue dispensing valve provided by the embodiment of the utility model, thread bush 402 is arranged in through-hole 4011 simultaneously
Be locked by locking member 41 and pedestal 401,403 thread bush 402 of screw rod is connected in thread bush 402, the lower end of screw rod 403 with
The upper end of the striker 30 has preset distance, to limit the stroke of the striker 30;Elastic component 404 is set to the valve body 10
Between pedestal 401, and the upper end and the lower end of the thread bush 402 offset, and lower end and the upper end of striker 30 offset, in this way,
Screw rod 403 can be made to move up and down by rotary screw 403, between 403 lower end of adjusting screw rod and the upper end of striker 30
Distance, and then the stroke of striker 30 is adjusted, it is locked between thread bush 402 and pedestal 401 furthermore, it is possible to be released by locking member 41
After state, rotation thread bush 402 makes thread bush 402 move up and down, to adjust the height and position of 402 lower end of thread bush, in turn
The initial length of elastic component 404 is adjusted, is adjusted as a result, by the initial length of the stroke adjustment of striker 30 and elastic component 404, it can
To realize out flow adhesive and spray the adjusting of pressure, meets dispensing needs, reach better dispensing effect.
Referring to shown in Fig. 2, in one embodiment of the utility model, pedestal 401 has to be communicated with the through-hole 4011
The first threaded hole 4012, first threaded hole 4012 coaxial arrangement is located at the top of the through-hole 4011, first spiral shell
The diameter of pit 4012 is less than the through-hole 4011, and the screw rod 403 is threadedly coupled with first threaded hole 4012, that is,
It says, screw rod 403 was both threadedly coupled with thread bush 402, can in this way, structure is more firm by being threadedly coupled with pedestal 401 again
It leans on, moreover, assembly is more convenient.
Advantageous, the outer peripheral surface of thread bush 402 is equipped with friction annular knurl 4021, and the side wall of the pedestal 401 is equipped with hollow out mouth
4013, the hollow out mouth 4013 is communicated with the through-hole 4011, to appear at least partly described friction annular knurl 4021.In this way,
When needing to adjust thread bush 402, it can be touched on the friction annular knurl 4021 that hollow out mouth 4013 goes out by finger, apply active force
The rotation of thread bush 402 can be driven, so that thread bush 402 moves up and down and realizes the adjusting of 404 initial length of elastic component,
Operation is adjusted to thread bush 402 convenient for user in it, meanwhile, it is simple and compact for structure.
More favorably, an adjusting knob 405 is stretched out from first threaded hole 4012 and be arranged in the upper end of screw rod 403,
The upper end of the adjusting knob 405 and the screw rod 403 is circumferentially fixed, to drive the screw rod 403 to rotate, in this way, needing
When adjusting screw rod 403, power drive screw rod 403 can be acted on by 405 application of adjusting knob and rotated, so that about 403 screw rod
It moves and realizes the adjusting of 30 stroke of striker, be convenient to user and operation is adjusted to screw rod 403, meanwhile, structure is simple
It is compact.
Shown in referring to Figure 2 to Figure 4, in some embodiments of the utility model, locking member 41 includes nut 412 and adjusts
Screw 411, the side wall of the pedestal 401 are equipped with the second threaded hole communicated with through-hole 4011,412 thread bush 402 of nut
Assigned on the adjusting screw 411, the adjusting screw 411 passes through 412 rear thread of nut and is connected to second screw thread
Hole.
In this way, stretching to the length on pedestal 401 in through-hole 4011 by the adjustable screw 411 of rotary screw, in turn
Thread bush 402 in through-hole 4011 is locked, after screw locks thread bush 402, by adjusting nut 412, so that nut
412 offset with pedestal 401, then can will adjust screw 411 and pedestal 401 is fixed, it is ensured that thread bush 402 is locked solid and reliable.
