Air inlet, the piston can slide up and down in cylinder, and the spring one end connects piston, and the other end connects cylinder bottom
Portion, the spring inner sleeve are taken over a job stopper rod, and the piston rod upper end connects piston, and the piston-rod lower end is passed through into glue valve
In plastic emitting valve, the piston rod is slidably matched with into glue valve, and the piston-rod lower end is equipped with sealing-plug, nature
Lower sealing-plug is bonded with into glue valve bottom end, described to be equipped with glue-feeder into glue valve side wall, it is described into be connected to inside glue valve into
Jiao Kou is equipped with annular channel, and the annular channel lower end is connected to plastic emitting valve, and the plastic emitting valve bottom is equipped with glue-spraying spout.
The utility model compared with prior art the advantages of be: by the flexible liter to adjust cylinder of electric pushrod
Drop, convenient for improving precision, air inlet makes piston move down compressed spring to cylinder intake, while driving piston rod, to make piston
The sealing-plug of bar bottom end connection is detached from into glue valve bottom end, is introduced into glue from glue-feeder and is flowed through annular channel and enters in plastic emitting valve,
It is discharged from plastic emitting valve bottom glue-spraying spout, when cylinder interior gas is discharged, spring force drives piston rod to move up, and makes under linkage effect
Sealing-plug be bonded with into glue valve bottom end again, because moving up for sealing-plug is born to what is generated in plastic emitting valve while stopping into glue
Pressure is so that glue-spraying spout glue resorption, it is therefore prevented that the situations such as water clock, the design of glue-spraying spout also further improve plastic emitting precision.
As an improvement, described be tightly connected into glue valve and plastic emitting valve, prevent glue from leaking.
As an improvement, the plastic emitting valve bottom is the arc of evagination, glue is facilitated to assemble to gum outlet.
As an improvement, the sealing-plug is round table-like, the convenient liquid inputted by glue-feeder that upper end is small, lower end is big
It is fallen into plastic emitting valve along sealing element circumferential surface.
As an improvement, the glue-spraying spout be it is coniform, further increase plastic emitting precision.
As an improvement, the junction of the glue-spraying spout and plastic emitting valve is arc lead angle, glue is facilitated to flow into glue-spraying spout.
Detailed description of the invention
Fig. 1 is a kind of high-precision controllable lift suck back valve structural schematic diagram of the utility model.
It is as shown in the figure: 1, electric pushrod, 2, cylinder, 2.1, piston, 2.2, spring, 2.3, air inlet, 2.4, piston rod, 3,
Into glue valve, 3.1, glue-feeder, 3.2, annular channel, 4, plastic emitting valve, 4.1, glue-spraying spout, 5, sealing-plug, 6, lead angle.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with Fig. 1, a kind of high-precision controllable lift suck back valve, including electric pushrod 1, the cylinder set gradually from bottom to top
2, into glue valve 3, plastic emitting valve 4, the lower end of the electric pushrod 1 is fixedly connected with 2 top of cylinder, is equipped in the cylinder 2
Piston 2.1 and spring 2.2, the top that piston 2.1 is located on 2 side wall of cylinder are equipped with air inlet 2.3, the piston
2.1 can slide up and down in cylinder 2, and described 2.2 one end of spring connects piston 2.1, and the other end connects 2 bottom of cylinder, institute
2.2 inner sleeve of spring stated is taken over a job stopper rod 2.4, and 2.4 upper end of piston rod connects piston 2.1,2.4 lower end of piston rod
It is set in plastic emitting valve 4 across into glue valve 3, the piston rod 2.4 is slidably matched with into glue valve 3,2.4 lower end of piston rod
Equipped with sealing-plug 5, sealing-plug 5 is bonded with into 3 bottom end of glue valve under natural conditions, described to be equipped with glue-feeder into 3 side wall of glue valve
3.1, described to be equipped with annular channel 3.2 into connection glue-feeder 3.1 inside glue valve 3,3.2 lower end of annular channel is connected to out
Glue valve 4,4 bottom of plastic emitting valve are equipped with glue-spraying spout 4.1.
Described is tightly connected into glue valve 3 and plastic emitting valve 4, and the piston rod 1.4 is connect with 8 bearing of valve rod, described
It is round table-like that sealing element 8.1 is that upper end is small, lower end is big.
In the specific implementation, by the flexible lifting to adjust cylinder 2 of electric pushrod 1, be fixed to needs the utility model
The height wanted, air inlet 2.3 makes piston 2.1 move down compressed spring 2.2 to 2 air inlet of cylinder, while driving piston rod 2.4, thus
The sealing-plug 5 for connecting 2.4 bottom end of piston rod is separated with into 3 bottom end of glue valve, is introduced glue from glue-feeder 3.1 and is flowed through annular channel
3.2 enter in plastic emitting valve 4, are discharged from 4 bottom glue-spraying spout 4.1 of plastic emitting valve, when gas in cylinder 1 is discharged, 2.2 elastic band of spring
Piston bar 2.4 moves up, and linkage effect is lower so that sealing-plug 5 be bonded with into 3 bottom end of glue valve again, while stopping into glue because of
Moving up for sealing-plug 5 makes 4.1 glue resorption of glue-spraying spout to the negative pressure generated in plastic emitting valve 4, it is therefore prevented that the situations such as water clock.
