The circular hole of central authorities, this spring base 292 is located among this pan feeding joint 260, this pan feeding spring 293 one end
It is butted on this spring base 292 other end and is butted on this pearl plug 291, it is possible to provide elastic force makes this pearl plug 291 clog this rubber
The circular hole of glue O 290 central authorities.
As it is shown in figure 5, when pan feeding first or when finding there is gas in raw material, this electric cylinder 30 can drive this
Push rod 22 rises to the position making this plunger 220 higher than this aerofluxus flash mouth 27, so fills when this pan feeding
Putting and sent into liquid raw material by this feeding mouth 26, this raw material will open this unidirectional pan feeding non-return valve 29
And making raw material enter among this stack shell 21, feed pressure can make the air in stack shell 21 by this aerofluxus flash
Mouthfuls 27 discharge, and because being not enough to open this unidirectional discharging non-return valve 28, and can make the raw material of injection can only court
On be filled with this stack shell 21, and when this raw material is full of the inside of this stack shell 21, the air in raw material can quilt
Extruded to avoid air cumulative effect discharging stable (air is compressible) by this aerofluxus flash mouth 27, and should
Raw material unnecessary in stack shell 21 also can be derived by this aerofluxus flash mouth 27.
As shown in Figure 6, when being full of raw material in this stack shell 21, this electric cylinder 30 can drive this push rod 22
Declining, the raw material among stack shell 21 will be pushed downwards by this plunger 220, now this unidirectional pan feeding check
Valve 29 can be cut out by the feed pressure within stack shell 21 and cannot countercurrently go out feeding mouth 26, this stack shell simultaneously
Feed pressure among 21 can open this unidirectional discharging non-return valve 28, and makes raw material flow into this syringe needle 23, then
It is injected to desired position.And after having injected, electric cylinder 30 can drive this push rod 22 to rise to make this
Plunger 220 is less than the position of this aerofluxus flash mouth 27, and this feeding device can be sent by this feeding mouth 26 simultaneously
Enter liquid raw material to filling up among this stack shell 21, then stop pan feeding, then make this electric cylinder 30 drive
This push rod 22 dynamic declines to push downwards the raw material among stack shell 21, so repeats above-mentioned to make this push rod
22 rise to make this plunger 220 less than the position of this aerofluxus flash mouth 27 and pan feeding and stop pan feeding also simultaneously
The action making this push rod 22 decline just can reach the most automatic injecting fluid and is precisely controlled the purpose of injection volume.
And, when in above-mentioned duplicate injection action when finding to have in raw material gas or be intended to it is cleaned
During operation, this push rod 22 just can be made again to rise to the position making this plunger 220 higher than this aerofluxus flash mouth 27
Put, with the air extruded in raw material or utilize this aerofluxus flash mouth 27 as cleaning time reflux cycle hole
So that cleaning operation.
The accurate liquid dispensing apparatus of trace provided by the utility model, this unidirectional pan feeding non-return valve 29 available with
The pressure of this unidirectional discharging non-return valve 28 and coordinate this aerofluxus flash mouth 27, when making pan feeding, raw material only can only be by
This feeding mouth 26 flows into and fills up the inside of this stack shell 21 without being flowed out by this discharging opening 24, and at note
When penetrating raw material the most only can only by this discharging opening 24 flow out without by feeding mouth 26 adverse current, and by should
Electric cylinder 30 also can be precisely controlled the propelling movement amount of this push rod 22, and then can therefore reach automatic feeding
And injection is to be precisely controlled injection volume, significantly saving manpower and to improve the purpose of work efficiency.And, should
Aerofluxus flash mouth 27 not only can derive the air in raw material to avoid the stable (air of air cumulative effect discharging
Compressible), and especially can be as reflux cycle hole during cleaning to increase the convenience of cleaning.
These are only preferred embodiment of the present utility model, be not limited to this utility model, right
For those skilled in the art, this utility model can have various modifications and variations.All in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection domain of the present utility model.
