Translation mechanism comprises joystick and spring; The lower end of joystick is provided with the mounting blocks of parallelogram, and mounting blocks is articulated on valve body; The middle part of spool is provided with annular projection, and spring housing is connected on outside spool and is compressed between the lower end and valve body of annular projection, and the upper end of annular projection is withstood in the lower end of mounting blocks; When pressing the free end of joystick, mounting blocks pushes up annular projection downwards, the downward translation of band movable valve plug; During release on control handle, spring is annular projection top upwards, the translation that makes progress of band movable valve plug.
Sense switch is miniature approach switch; When pressing joystick, joystick detection trigger switch.
Suck back valve comprises into the glue chamber; The lower end of valve body is socketed on into the upper end in glue chamber, and the upper end of valve head is socketed on into the lower end in glue chamber; The lower end of spool arranges the seal head with the spool translation, and seal head withstands or away from the gum outlet that enters lower end, glue chamber and arrange.
The inside of glue discharging mouth, the inside of valve head, the inside of entering the glue chamber are communicated with successively, enter the glue chamber and a gumming pump joins by pipeline, and gumming pump and a glue tank join by pipeline; Sense switch is electrically connected to gumming pump.
Be provided with the resorption chamber in valve head.
Valve body is equipped with the limited block of convex, and spool is provided with the stopper slot of the indent of above-below direction extension, and limited block is stuck in stopper slot; During the upper end in contact of limited block and stopper slot, to the spool lower limit; During the lower end in contact of limited block and stopper slot, to the spool upper limit.
Valve body with enter the glue chamber and connect by the internal and external threads fit, valve head and enter the glue chamber by the connection of internal and external threads fit.
Glue discharging mouth is connected the internal and external threads fit and connects with valve head.
Generally speaking, the utlity model has following advantage:
1. profile is small and exquisite, and is convenient mobile in a glue process; Simple in structure, making and easy for installation.
2. press joystick and can realize opening suck back valve and open gumming pump for the dual-use function of glue, reduce workman's manipulation strength.
3. sense switch is set controls the gumming pump action, prevent that sebific duct pressure that cause is excessive or the sebific duct Decrepitation Phenomena for glue is asynchronous with the valve startup, increases equipment life.
4. during valve closing, because spool and seal head reduce in the suck back valve inner volume, less volume is replenished by glue, therefore realizes the resorption function, avoids glue discharging mouth to drip the glue situation and occurs.After the resorption chamber is set, strengthen the resorption effect.
Description of drawings
Fig. 1 is broken away view of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is along the cutaway view of A-A direction in Fig. 2.
Wherein, 1 is valve body, and 2 is valve head, and 3 is glue discharging mouth, and 4 is spool, and 5 is spring, and 6 is joystick, and 7 is sense switch, and 8 for entering the glue chamber, and 9 is seal head, and 10 is annular projection, and 11 is the resorption chamber, and 12 is mounting blocks, and 13 is limited block, and 14 is stopper slot.
The specific embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is to shown in Figure 3, and a kind of novel manual is controlled suck back valve and comprised: valve body 1, valve head 2, glue discharging mouth 3, spool 4, spring 5, joystick 6, sense switch 7, advance glue chamber 8, seal head 9.
The center of valve body 1 arranges and shape and spool 4 corresponding cavity volume that pass for spool 4.The sidewall of valve body 1 is provided with opening, is used for the installation of joystick 6 and the installation of sense switch 7.Valve body 1 is equipped with the limited block 13 of convex near the inwall of upper end.
Valve head 2 is fixed on the lower end of valve body 1, is provided with resorption chamber 11 in valve head 2.
Sense switch 7 is miniature approach switch; When pressing joystick 6, the detection trigger switch.Sense switch 7 starts and advances the glue action into the glue pump by detecting the suck back valve opening.
Enter glue chamber 8 and be provided with external screw thread, the screw-internal thread fit of the first half and spool 4, both fits connect; The screw-internal thread fit of the latter half and spool 4, both fits connect.The lower end of entering glue chamber 8 is provided with gum outlet.The inside of advancing glue chamber 8, valve head 2 and glue discharging mouth 3 communicates with each other.Enter glue chamber 8 and join by pipeline and a gumming pump, gumming pump joins by pipeline and a glue tank, and sense switch 7 is electrically connected to gumming pump.
During use, press joystick 6, mounting blocks 12 promotes annular projections 10 and moves down, and moves down thereby spool 4 drives seal heads 9, and seal head 9 leaves into the glue chamber 8 gum outlet, and suck back valve is opened; Simultaneously, joystick 6 is because pressing detection trigger switch 7, and sense switch 7 transmits control signal and controls gumming pump and open; Glue from the glue tank flow through successively gumming pump, advance glue chamber, valve head, flow out from glue discharging mouth at last.When handle 6 was pressed in relieving, annular projection 10 moved under the effect of spring 5, thereby spool 4 drives on seal heads 9 and moves, and seal head 9 withstands into the glue chamber 8 gum outlet, and suck back valve is closed; Simultaneously, joystick 6 leaves sense switch 7, and sense switch 7 transmits control signal and controls gumming pump and cut out; When suck back valve was closed, the volume in valve head 2 reduced due to spool 4 and seal head 9, and the volume that reduces is filled by glue, added the effect in resorption chamber 11, and glue resorption when suck back valve is closed is avoided 3 glue of glue discharging mouth.
Above-described embodiment is the better embodiment of utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
