With valve body lower case 2, valve body lower case 2 is equipped with striker hole, and sliding is equipped with striker 9 in striker hole, valve body lower case 2 be additionally provided with
The glue inlet tube road of striker hole connection, lower case external screw-thread are connected with limit swivel nut 1, and limit 1 bottom end of swivel nut is equipped with and striker hole
The nozzle 11 of connection, striker 9 and nozzle 11, which are hit, realizes glue spraying,
There is cavity inside valve body upper housing 3, lever 5 is installed in valve body upper housing 3, cavity top is fixed with piezo stack
Heap 6, striker 9 are deep into cavity inside and are fixed on one end of lever 5, and piezoelectric stack 6 is withstood on lever 5, is cased with outside striker 9
Elastic element, described elastic element one end are withstood on lever 5, and the elastic element other end is pressed on valve body upper housing 3；
The displacement sensor probe 7 for detecting 5 moving distance of lever is equipped in cavity.
As embodiment of the invention, piezoelectric stack 6 withstands on the position between 9 fixing end of 5 installation point of lever and striker,
Elastic element is spring 8, and spring 8 is compressed spring.
Ejecting adhesive dispenser further includes valve body controller 12, and signal is transmitted to valve body controller 12 by displacement sensor probe 7,
Valve body controller 12 controls piezoelectric stack 6 simultaneously, has on valve body controller 12 for showing displacement sensor probe 7 and lever
The display of distance between 5.
Lever 5 is mounted on valve body upper housing 3 by pin shaft 4.
Groove is equipped in valve body lower case 2 above striker hole, is fixed with sealing ring 10 in groove, 10 sets of sealing ring are being hit
On needle 9.
A kind of adjusting method of the ejecting adhesive dispenser of above-mentioned feedback regulation, comprising the following steps:
Step 1: being received after the signal that valve body controller 12 issues by displacement sensor probe 7, displacement sensor
Probe 7 detects the distance between lever 5, then feeds back to valve body controller 12, and valve body controller 12 is by receiving
Signal conversion processes be shown in controller display；
Step 2: in the bottom end just contact nozzle 11 of striker 9, displacement sensor probe 7 measures one away from lever 5
Spacing, being shown in is an initial value on valve body controller 12, adjusts limit swivel nut 1 and nozzle 11 is driven simultaneously to withstand thick stick by striker 9
Bar 5 is moved upwards up to the spacing of a normal injection, and displacement sensor probe 7 is measured another spacing away from lever 5 and is shown in
It is another spacing on valve body controller 12；
Step 3: the moving distance of nozzle 11 is shown by two pitch differences.
Working principle:
Valve body controller 12 issues pulse signal to the piezoelectric stack 6 in valve body 13, and piezoelectric stack 6 is upon receipt of the signals
Periodic expanding-contracting action is done according to pulse signal, while driving striker 9 does periodicity after the effect of the displacement equations of lever 5
It fast moves；Glue is by air pressure from the glue inlet tube road flow nozzle 11 in valve body lower case 2；In the feelings for normally forming injection
Under condition, striker 9 will receive the position limitation of nozzle 11 when being moved to least significant end；Since quickly moving back and forth up and down for striker 9 is hit
Nozzle 11 is hit, the glue in nozzle 11 to form injection by knocking out from the aperture of 11 bottom end of nozzle, this process needs are hit
Hit the adhesion strength that power is greater than glue itself.
