Description
Technical field
The invention belongs to the plastic emitting valve arrangement technical field of improvement of dispenser, and in particular to a kind of AB dispensers plastic emitting screw rod
Injection valve.
Background technology
AB dispensers, namely two-fluid glue dispenser, compared with general single-component glue water dispenser, can adapt to two-component
Glue mixing match dispensing, is spot gluing equipment more mature at present.In this kind of dispenser, plastic emitting valve is more crucial portion
Part, the valve port on its valve body top are used to connect glue bucket, and the valve port of lower part is connected with dispensing needle head, while air admission hole is provided with valve body
The internal valve road of connection and exterior air pump equipment, for providing air pressure with plastic squeeze, while easy to control out flow adhesive.It is but known
The plastic emitting valve exposes following problem in practice：
1）Valve road in valve body is straight pipeline, and dispensing gap is even residual in idle state not with air pressure capable of being increased, valve road
Glue is also easily flowed out from lower part valve port under the effect of gravity, and most the jet port through syringe needle drips to outside afterwards, causes environment and product
Pollution, influence beauty, while add manual cleaning cost；
2）The not state that is mixed thoroughly when AB glue is inputted to valve by respective glue bucket respectively, by valve during plastic emitting
Pressurize in road to accelerate turbulent fluctuation inside glue, play certain immixture.But because valve road is straight pipeline, glue can not be provided
With enough loading ends and air pressure coordinative role, therefore the effect mixed is not satisfactory.
3）The equipment such as external air pump and air inlet pipeline are needed, it is cumbersome, and to pay attention at the moment balancing in valve road during pressurization
Pressure, prevent valve break down and can not dispensing, work unreliability improve；
4）Known valve body is made by PP materials, and when glue temperature is higher, valve body expands with heat and contract with cold substantially, cause valve road and
Valve port deformation is more, can not control out flow adhesive well, substantially reduce accuracy of spray.
The content of the invention
The present invention seeks to：For deficiency existing for the existing plastic emitting valve involved in background technology, and provide a kind of AB points
Glue machine plastic emitting screw rod injection valve, it being capable of effectively preventing from cementing leakage phenomenon, and help greatly to improve AB glue liquid in valve road
Mixed effect.
The technical scheme is that：A kind of AB dispensers plastic emitting screw rod injection valve, including valve body and perforation valve body are perpendicular
Straight valve road, outlet is gum outlet under the valve road of body base；It is characterized in that it is provided with what is be connected with valve road on the valve body
Glue feeding opening, further includes servomotor and the screw rod by servomotor driving rotating, and the screw rod passes through positioned at body top
Valve road upper outlet stretch into valve road, formed together with valve road and drive glue to be ejected from the jet port on the dispensing needle head
Screw press room.
Further, the ratio of the pitch s and major diameter d of heretofore described screw rod are 1/3 ~ 1.
Further, the ratio of heretofore described screw rod major diameter d and valve road internal diameter D is 3/4 ~ 4/5.
Further, heretofore described valve road inner wall surface is that the rough surface of protrusion is distributed with, and rough surface can
More preferable drag is provided, preventing from cementing leakage phenomenon occurs.And during screw rod rotary presser, coarse valve road inner wall surface is again
The frictional impact with glue particle can be increased, further improve mixed effect.
It is more highly preferred to, heretofore described valve road inner wall surface is uniform and continuous ripple.
Further, heretofore described valve body is metal valve body, such as iron valve body, copper valve body, stainless steel body, aluminium valve
Body etc..Metal valve body can reduce the change expanded with heat and contract with cold and brought caused by glue temperature, it is ensured that plastic emitting flow control it is steady,
Improve dispensing precision.
Further, heretofore described glue feeding opening is connected with A, B glue bucket at the same time through Y shape injected rubber hose.With routine techniques one
Sample, A, B glue bucket are respectively used to store different glues, during specific works, A, B glue bucket open at the same time by Y shape injected rubber hose and into
Glue hole injecting glue into valve road.
Further, sealing ring is equipped between heretofore described screw rod and valve road upper outlet, it is ensured that glue will not pass through
Valve road upper outlet overflows and pollutes servomotor.
Further, bearing block is equipped between heretofore described servomotor and body top, set is equipped with bearing block
The bearing being placed on screw rod.The setting purpose of bearing is to ensure that the stationarity and fluency of screw rod rotation.
In actual use, the present invention is the same with routine techniques, the gum outlet connection dispensing needle head of body base, on valve body
Glue feeding opening connects A, B glue bucket through Y shape injected rubber hose.A, B glue bucket lower valve door latter two glue are opened through Y shape injected rubber hose and glue feeding opening
Flow into valve road.At this time, start servomotor driving screw rod to rotate forward, it becomes with the volume in valve road inner wall gap when rotating because of screw rod
Change and produce extrusion pressure（Screw press room effect）, glue is squeezed into dispensing needle head, finally from the jet port spray on dispensing needle head
Go out to implement dispensing operation.In screw rod rotary course, glue is stirred, the effect of mixing is actually also functioned to, substantially increases
A, B glue mixed effect.
After one product dispensing, servomotor driving screw rod inverts, and glue is oriented because being driven by screw rod inside valve road
The trend of upper movement, therefore gravity can be overcome to be dripped without gum outlet from below, effective preventing from cementing leakage phenomenon occurs.When product more
Change and finish, servomotor driving screw rod, which rotates forward, to be repeated to implement dispensing operation.
It is an advantage of the invention that：
1）This AB dispensers plastic emitting screw rod injection valve provided by the invention, it introduces screw rod composition in the valve road of valve body
Screw press room, is rotated forward by Serve Motor Control screw rod and is pressurised into glue and provides injection power, and while inverting then produces drive
The trend that glue moves upwards so that glue is not easy to drip under the effect of gravity, therefore the leak adhesive that effectively prevent dispensing gap shows
As.Cleaning and the beauty of environment and product are not only ensured, while has saved glue and manual cleaning cost.
2）During Serve Motor Control screw rod rotary presser in the present invention, because stirring glue, actually also function to
The effect of mixing, substantially increases the mixed effect of A, B glue, helps further to improve dispensing product quality.
3）Heretofore described valve body is metal valve body, and metal valve body can reduce the band that expands with heat and contract with cold caused by glue temperature
The change come, it is ensured that steady, the raising accuracy of spray of plastic emitting flow control.
4）Heretofore described valve road inner wall surface is that the rough surface of protrusion is distributed with, and rough surface is capable of providing more preferably
Drag, preventing from cementing leakage phenomenon occur.And during screw rod rotary presser, coarse valve road inner wall surface can increase again with
The frictional impact of glue particle, further improves mixed effect.
5）The present invention is rotated forward by Serve Motor Control screw rod compared to conventional dispensing valve and is pressurised into glue offer injection
Power, eliminates the installation and debugging of the equipment such as air pump and air inlet pipeline, simplifies operation, is put down without the pressure in worry valve road
Weighing apparatus problem, reduces failure rate, improves functional reliability.
