Finite place piece 10 is set in the second main body 2, and the effect of locating part 10 is the stroke for controlling pedestal, so that pedestal
The extreme lower position of downlink is the top end surface of locating part 10.Its object is to avoid pedestal from excessively moving downward, lead to bellows
It is excessively compressed for a long time, reduced lifetime.
As shown in Figure 1, glue pipe fitting 9 is equipped at the corresponding glue-feeder of the second main body 2, for connecting with extraneous tube of glue
It connects, glue is transported in the second cavity.
As shown in Figure 1, causing the first cavity due to gas compression when gas enters the first cavity from air inlet
Air pressure increases, and sealed envelope part 5 shrinks and drives the pedestal 4 that is arranged on sealed envelope part 5 to Forward under the promotion of air pressure
Dynamic, to open gum outlet 8, simultaneously because also there is storage cavity inside sealed envelope part 5, (the storage cavity is by gas compression
When can become smaller), the glue of part is contained, when sealed envelope device is shunk under the action of the air pressure of the first cavity, so that
Pressure increase in two cavities and storage cavity, the second cavity and the glue for storing cavity can be sprayed outward by gum outlet 8
Out.When not needing to pump out glue, no longer to the first cavity air inlet, and sealed envelope part 5 is in spring or the effect of air pressure
Under return to original position, when storage cavity also returns to original size, the pressure reduction of glue chamber, glue is automatically flowed into or is inhaled
Enter inside cavity, supplements glue to the second cavity and storage cavity.It should be understood that the design of gum outlet 8 may not in the present embodiment
For vertically downward, glue can not just flow out automatically by gravity under normal circumstances in this way.
Although can also achieve in the present embodiment not against spool it should be understood that joined spool in Fig. 1 and Fig. 2
Control the technical effect of glue disengaging.
Embodiment 2
Unlike the first embodiment, in order to which the outflow for preferably controlling glue adds in this programme as depicted in figs. 1 and 2
Enter spool 11, on the pedestal 4 for being threaded in sealed envelope device of the spool 11, passes through pressure control sealed envelope part 5
It stretches to drive spool 11 mobile to open and close gum outlet 8.
In order to enable spool 11 can move without left and right offset along fixed-direction and often strike at hair mouth (i.e. gum outlet
8), so that the case where avoiding stuck or leak adhesive appearance, sealed envelope device further include for 11 direction of motion of guide spool
Guide pad, the guide pad are arranged on the first main body 1, the second main body 2 or sealed envelope part 5, it is arranged in the present embodiment
In the second main body 2.In order to realize guiding role, guide pad is equipped with the second guiding to match with spool 11 in the present embodiment
Through-hole, the cross section of second guide through hole are circle.
In order to better ensure that spool 11 will not roll at valve nozzle, this programme is equipped at gum outlet 8 and spool
The rear end of 11 the first guide through hole to match, spool 11 is moved at gum outlet 8 along fixed track along the first guide through hole
It is dynamic.The cross section of first guide through hole is circle.
When gas enters the first cavity from air inlet, the air pressure of the first cavity is caused to increase due to gas compression,
Sealed envelope part 5 shrinks and drives the pedestal 4 being arranged on sealed envelope part 5 and spool 11 mobile under the promotion of air pressure,
To open gum outlet 8.When not needing to pump out glue, no longer to the first cavity air inlet, sealed envelope device in spring or
It is resetted under the action of air pressure, and moves back to original position with movable valve plug 11, block gum outlet 8, so that glue can not be to outflow
Out.This programme avoids sealing element 3 (i.e. existing by fixing and by sealed envelope device sealing element 3 come the band movement of movable valve plug 11
Have the structures such as piston and the diaphragm of technology) friction occurs with the inner wall of the first main body 1 or the second main body 2 when moving and is ground
Damage, avoids the first cavity from being connected to the second cavity since sealing element 3 is worn, guarantees the sealing performance of this programme.It should be understood that
Telescopic device, which does not need to be resisted against on the inner wall of the first main body 1 or the second main body 2, in this programme realizes sealing.
Embodiment 3
It is not both that the front end of the sealed envelope device is resisted against in the first main body 1, so that sealed envelope with embodiment 1
Third cavity, the third cavity and the first cavity and the second cavity are formed between device, the first main body 1 and sealing element 3
Mutually isolation.More precisely, pedestal 4 is resisted against in the first main body 1, and pedestal 4, sealed envelope part 5, the first main body 1 with
And third cavity is formed between sealing element 3.Since third cavity and the first cavity and the second cavity mutually completely cut off, hold first
The third cavity of isolation is set between chamber and the second cavity, and what the air for further decreasing the first cavity entered the second cavity can
Energy property, improves the air-tightness of device.
Embodiment 4
Unlike the first embodiment, in the present embodiment, driving device is to reset motor, and the reset motor is described multiple
Position motor is fixed in the first main body and output end is connect with the front end (i.e. pedestal) of sealed envelope device, for band dynamic sealing packet
The pedestal wrapped up on device is mobile relative to sealing element, so that the expansion of storage cavity or contraction.
In order to allow the pressure of the first cavity to keep constant, gas outlet or air inlet, institute can be set in the first main body
Gas outlet and air inlet is stated to be connected to the first cavity.
Embodiment 5
As shown in figure 3, the first main body Yu the second main body of rubber injecting valve are integrally formed in the present embodiment, but it is also classified into the first appearance
Chamber and the second cavity, it should be noted that in the second main body be equipped with the first guide through hole 12, by the first guide through hole 12 come
The movement of guide spool 11.And in the second main body, it also is provided with venthole by the first guide through hole 12, is mainly used to allow
Two cavities are communicated with the atmosphere, and guarantee that the pressure in the second cavity is equal with atmospheric pressure.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
