Description
Technical field
The present invention relates to a kind of dispenser piezo electric valve jet port anti-block apparatus.
Background technology
The piezo electric valve jet port used at present on dispenser belongs to precision manufactureing, is driven by piezo-activator inside it
One group of movable plate activity in valve road, gel quantity is controlled by the gradient of movable plate folding.Compared to pneumatic operated valve, although piezo electric valve goes out
Glue control accuracy higher, reaction are also sensitiveer, but bring expensive, the problem of maintenance cost is high at the same time.Actually using
During need extreme care.
But in known dispensing operation process, piezo electric valve jet port is often blocked because glue solidifies（Such as point
The glue gap replacement product time is more long, or human negligence）, need to dredge it for this.Dredging mode traditional at present
Dredged for contact, i.e., the colloid of piezo electric valve jet port is manually removed using metal thimble or like instrument, shortcoming is easily broken
Bad valve road built-in component, or valve road inner wall is dampened, cause the operating accuracy of piezo electric valve to be greatly reduced；And manually dredge efficiency
It is low, also increase human cost.
The content of the invention
The present invention seeks to：A kind of dispenser piezo electric valve jet port anti-block apparatus is provided, which is dredged using contactless
Logical mode blocks to eliminate, and compared to known technology, can effectively prevent the destruction to piezo electric valve jet port, and without manually joining
With can greatly improve production efficiency to a certain extent.
The technical scheme is that：A kind of dispenser piezo electric valve jet port anti-block apparatus, including valve body, in valve body
Valve road and the jet port positioned at valve road bottom；It is characterized in that the valve road is fixed with electricity on the inner wall of bottom jet port
Backing, also supports between the electric heating piece and valve road inner wall and sets a pressure sensor, the pressure sensor and driving electric heating piece break-make
Controller be electrically connected.
Further, heretofore described valve road inner wall is equipped with groove, and the electric heating piece is in the groove, institute
Pressure sensor is stated to support between the wall of the electric heating piece and groove.
Further, heretofore described groove is annular groove, and the electric heating piece is matched with the annular groove
Annular electric heating piece.Annular electric heating piece is beneficial to the thermally equivalent of gel, can accelerate glue flowing, make jet port faster unimpeded.
Preferably, the piezo electric valve jet port of blocking is checked for the ease of worker, present invention additionally comprises with electric heating piece
The LED of series connection, the LED are provided separately with electric heating piece, and the mounting hole for LED insertions is provided with the valve road inner wall.It is for example, real
When border is assembled, LED can be located at the side of electric heating piece, or can also be located at electric heating piece（For annular electric heating piece）'s
It is upper and lower.
Alternatively, in another embodiment, the LED can be arranged on and be embedded in the groove of electric heating piece and positioned at electricity
On the inside of backing, it is provided with the electric heating piece for the LED openings stretched into or through hole.Opening and through hole purpose is set to be easy for LED hairs
The light gone out can be appeared to valve road.
Further, it is that the electric heating piece for ensuring to add does not interfere the valve road internal diameter of piezo electric valve in itself, the electricity in the present invention
Inner wall surface of the backing towards the inner wall surface of the surface of valve road and valve road flush or below valve road.
Further, heretofore described controller is PLC or PC.
The operation principle of the present invention is as follows：
When the solidification of piezo electric valve jet port glue causes to block, pressure increase in valve road, the pressure is through on valve road inner wall
Electric heating piece reaches pressure sensor, and when more than default critical value, pressure sensor sends signal to controller, then by controlling
Device sends drive signal driving electric heating piece circuit closed conducting.Glue in electric heating piece heating valve road so that glue mobility strengthens,
So as to smooth outflow.After series LED on electric heating piece, while controller driving electric heating piece heats, also LED is driven to send
Illumination, has the permeability in valve road easy to worker and intuitively detects.
Certainly it is to be appreciated that electric heating piece, pressure sensor, LED and its connection control technology involved in the present invention are
Routine techniques, is well known to those skilled in the art, therefore this is no longer described in detail in the present invention.
It is an advantage of the invention that：
1. apparatus of the present invention are blocked using contactless dredging mode to eliminate, compared to known technology, can effectively prevent
Destruction to piezo electric valve jet port, and without manually participating in, the degree of automation is high, can greatly improve life to a certain extent
Produce efficiency.
2. apparatus of the present invention introduce the LED to connect with electric heating piece in the scheme of optimization, electricity is driven when jet port blocks
When backing heats, LED can also be automatically opened up, and had easy to worker to the permeability in valve road and intuitively detected.
