further, the road of valve described in the present invention inwall is provided with groove, and described electric heating piece is flush-mounted in described groove, and described pressure sensor is between the wall being located at described electric heating piece and groove.
further, groove described in the present invention is annular groove, and described electric heating piece is the annular electro backing mated with described annular groove.Annular electro backing is beneficial to the thermally equivalent of gel, can accelerate glue flowing, make jet unimpeded sooner.
preferably, check the piezo electric valve jet of blocking for the ease of workman, the present invention also comprises the LED connected with electric heating piece, and described LED and electric heating piece are provided separately, and described valve road inwall has the installing hole embedded for LED.Such as, during practical set, LED can be positioned at the side of electric heating piece, or also can be positioned at the upper and lower of electric heating piece (for annular electro backing).
or, in another embodiment, be positioned at inside electric heating piece in the described groove that described LED can be located at setting-in electric heating piece, described electric heating piece have the opening or through hole that stretch into for LED.Arranging opening and through hole object is be convenient to the light that LED sends can appear in valve road.
further, for guaranteeing that the electric heating piece set up does not interfere the valve road internal diameter of piezo electric valve itself in the present invention, described electric heating piece flushes towards the surface in valve road with the inner wall surface in valve road or lower than the inner wall surface in valve road.
further, controller described in the present invention is PLC or PC.
operation principle of the present invention is as follows:
when piezo electric valve jet glue solidify cause blocking time, in valve road, pressure increases, the electric heating piece of this pressure on valve road inwall reaches pressure sensor, when exceeding default critical value, pressure sensor sends signal to controller, then sends the conducting of drive singal driving electric heating piece circuit closed by controller.Glue in electric heating piece heating valve road, makes glue mobility strengthen, thus can smooth and easyly flow out.When after series LED on electric heating piece, controller also orders about LED and sends illumination while driving electric heating piece heating, and being convenient to workman has the permeability in valve road and to detect intuitively.
certainly need to illustrate, the electric heating piece related in the present invention, pressure sensor, LED and connection control technology thereof are routine techniques, be well known to those skilled in the art, therefore the present invention no longer describe in detail this.
advantage of the present invention is:
1. apparatus of the present invention adopt contactless dredging mode to eliminate blocking, compare known technology, effectively can prevent the destruction to piezo electric valve jet, and without the need to artificial participation, automaticity are high, can enhance productivity greatly to a certain extent.
2. apparatus of the present invention introduce the LED that connect with electric heating piece in the scheme optimized, and order about electric heating piece when jet blocking when heating, LED also can open automatically, and being convenient to workman has the permeability in valve road and individually to detect intuitively.
