The utility model content
The technical problem that the utility model will solve is that the manual air-operated of discharging in the glue dispensing valve of present glue dispensing valve is loaded down with trivial details; And processing, disassembly, cleaning, replacing sealing ring etc. are also inconvenient; Processing cost is than higher, provide for this reason a kind of can automatic vent and the glue dispensing valve of easy accessibility.
The technical scheme of the utility model is: glue formula glue dispensing valve is told in a kind of injection; It comprises the branch pump housing and the main pump body that is fixed in branch pump housing top; Have the slideway that supplies injection rod to move up and down in the said main pump body; Main pump body one side is connected with the exhaust bubble piece that has steam vent, and the pump housing one side was connected with and the liquid inlet joint of dividing the pump housing to be connected in said minute, and said liquid inlet joint is communicated with the sebific duct that fills colloid.Divide pump housing bottom to be connected with and the draining connector that divides the pump housing to be connected, divide in the pump housing adaptive have play that the control branch pump housing is communicated with draining connector or the core assembly of cutting action.
The improvement of such scheme is that said core assembly comprises and has the spool and the valve pocket that can rotate relative to valve pocket that be communicated with to divide passage between the pump housing and the draining connector, and said valve core housing is located in the valve pocket.
The further improvement of such scheme is that said core assembly is a ceramic component.
Further improving again of such scheme is to be connected with pump gland between said minute pump housing and the main pump body.
Further improving of such scheme is that injection rod and the exhaust on said exhaust bubble piece top steeped on the injection rod of piece bottom and be tightly connected with sealing ring through injection rod with main pump body.
Further improving again of such scheme is that said injection rod is connected with stepper motor.
The beneficial effect of the utility model is to realize emptying airway dysfunction in the valve pocket through the colloid that repeatedly extracts in the sebific duct; Adopt the injection rod mode to tell glue simultaneously; Injection rod is by step motor driven, can realize that high accuracy tells glue, meets the manufacturing technique requirent of LED simultaneously; Be convenient to dismounting and cleaning, easy to maintenance.
Description of drawings
Fig. 1 is the utility model organigram;
Fig. 2 is the utility model scheme of installation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Like Fig. 1, shown in Figure 2; Glue formula glue dispensing valve is told in a kind of injection; It comprises the branch pump housing 4 and the main pump body 7 that is fixed in the branch pump housing 4 tops, has the slideway that supplies injection rod 12 to move up and down in the said main pump body 7, and main pump body 7 one sides are connected with the exhaust bubble piece 8 that has steam vent; The pump housing 4 one sides were connected with and the liquid inlet joint of dividing the pump housing 4 to be connected in said minute, and said liquid inlet joint is communicated with the sebific duct that fills colloid.Divide the pump housing 4 bottoms to be connected with and the draining connector that divides the pump housing 4 to be connected, dividing adaptively in the pump housing 4 has the control played minute pump housing 4 to be communicated with draining connector or the core assembly of cutting action.
The preference of the utility model is to be connected with pump gland 9 between the branch pump housing 4 and the main pump body 7; Pass through injection rod with sealing ring 10 with main pump body 7 respectively on the injection rod 12 of the injection rod 12 on exhaust bubble piece 8 tops and exhaust bubble piece 8 bottoms; 11 are tightly connected; Core assembly comprises and has the spool and the valve pocket that can rotate relative to valve pocket that be communicated with to divide passage between the pump housing 4 and the draining connector, and said valve core housing is located in the valve pocket, and spool and valve pocket all are ceramic materials; Strengthen sealing through valve core seal ring 5 between spool and the valve pocket, injection rod 12 is connected with stepper motor.
As shown in Figure 2, be connected with the syringe needle of being with the pin mouth under the draining connector of the branch pump housing bottom of the utility model, syringe needle is connected the branch pump housing 4 lower ends through pin mouth fixed cover 6, and all sides of draining connector are provided with the external screw thread of M6 in order to pin mouth fixed cover 6 to be installed.Injection rod 12 is installed on the drive division 1 that has stepper motor through injection rod fixed block 2.The hole of dividing pin hole that diameter 4mm is arranged on the pump housing 4 and the diameter 9mm that valve pocket is installed is fixed through two screws as the location of the pump housing on drive division again.One end of spool is provided with the square groove that makes valve core rotation.The square groove that only needs rotational valve core; Make valve core rotation, the passage in this moment spool departs from the passage in the valve pocket mutually, and then the passage in the spool no longer is connected with passage in the valve pocket; Thereby make valve pocket be in closed state, also be valve pocket and draining connector the two be in dissengaged positions.Sebific duct is installed on the injection seat 3.Divide the pump housing 4 to be connected with drive division 1 through screw.
When using the utility model; At first make valve core rotation and make valve pocket and draining connector the two be in dissengaged positions; Move on on the injection rod then and break away from the injection rod sealing ring 10 be arranged in exhaust bubble piece bottom and suck valve pocket to the colloid that is stored in sebific duct, after repeatedly, just have in the aperture of colloid from the exhaust bubble piece and flow out; The colloid that flows out is contained in the exhaust bubble piece cup; Till not containing bubble in the colloid that in the aperture of seeing from the exhaust bubble piece, flows out, this process approximately needs 5-10 time, and after this injection rod no longer breaks away from and is positioned at the injection rod sealing ring that the piece bottom is steeped in exhaust; Above step is also not have colloid in the valve pocket when being installed on the driver for pump through cleaning; Be full of the action that the bubble-free colloid first step is accomplished in the pump housing in order to make, normal point glue does not need to carry out above operation again as long as pump is not lifted down cleaning, has been full of bubble-free colloid because of operating in the pump housing of back through this.Then make valve core rotation switching-over so that valve pocket and draining connector the two be in connected state, press down by the step motor driven injection rod again, spue colloid through the pin mouth that links to each other with draining connector; After colloid spues and accomplishes; Spool once more Rotation With Changing to, at this moment valve pocket and sebific duct communicate once more, the injection rod return; Suck colloid once more in the valve pocket, to accomplish actuation cycle one time.
