Abstract
The invention provides a dispensing valve. The dispensing valve comprises an air cylinder shell, a piston rod, valve cores, a glue inlet valve body and a glue outlet valve body; the piston rod perpendicularly penetrates through the upper half part of the air cylinder shell; the valve cores comprise a first valve core and a second valve core which is identical to the first valve core, and both the first valve core and the second valve core are connected to the lower end of the piston rod and symmetric to each other in the lateral direction of the piston rod; a first combined coil, a second combined coil, a third combined coil and a fourth combined coil are arranged in the glue inlet valve body. The dispensing valve has the beneficial effects that the sealing performance of contact surfaces of the valve cores and glue is improved by adopting the combined coils, and the failure of the dispensing valve caused by the entry of the glue into the valve cores can be avoided; the combined coils are matched with the valve cores, so that a valve effect is realized; in addition, the sealing performance of the valve is improved through the combined coils, gas leaking from the air cylinder is prevented from entering the glue inlet valve body, and when the valve is closed, the glue entering the glue inlet valve body is prevented from flowing into the glue outlet valve body; each combined coil is simple in structure, easy to install and convenient to replace.
Description
Technical field
The present invention relates to a kind of glue dispensing valve, particularly relate to a kind of glue dispensing valve that two component water is mixed automatically.
Background technology
Point gum machine, also known as glue spreader, adhesive dripping machine, adhesive supplier etc., is control fluid specially, and by fluid drop, the automatic machinery being coated on product surface or interiors of products.Point gum machine is mainly used in glue, paint and other liquid Accurate Points in Product Process, note, painting, point drip to each product exact position, can be used for that realization is got ready, setting-out, round or camber.
Glue dispensing valve is parts very important in point gum machine, and glue dispensing valve is generally divided into pneumatic and electronic two kinds.Operationally, compressed air sends into glue bottle to pneumatic glue dispensing valve, glue laminated is entered in the service pipe be connected with piston chamber, when piston is in upstroke, fills up glue in piston chamber, and when needle head is dripped in cold downward propelling of living, glue extrudes from pin mouth.The glue amount oozed is determined by the distance of piston undershoot, can manual adjustment, also can control in software, the pass glue of pneumatic glue dispensing valve adopts updraft type to close plastic structure, make to stop glue simultaneously moment resorption to break glue, reduce the cull that remaining syringe needle is foretold, make a glue not produce the phenomenon such as drip, wire drawing.
In prior art, cylinder is when driving glue dispensing valve point glue, cylinder easily leaks gas, and the gas spilt in cylinder easily enters into into glue valve body, thus the problem causing the some glue such as wire drawing, water clock, glue point cavity and glue point weight change inconsistent, therefore be necessary to prevent the gas in cylinder from entering into into glue valve body; In addition, when piston rod promotes valve core movement, the glue entered in glue valve body also likely enters in spool, and cause glue dispensing valve fault and quit work, therefore, the sealing that spool is entering glue valve inner and glue-contact face is of crucial importance.
Summary of the invention
The object of the present invention is to provide the glue dispensing valve of strong, the low fault of a kind of sealing property, solve gas that cylinder in prior art spills and to enter into into glue valve body thus Influential cases colloid amount, the glue entered in glue valve body enter the problem that spool causes glue dispensing valve fault.
Technical scheme of the present invention is achieved in that
A kind of glue dispensing valve, it comprises cylinder shell, piston rod, spool, enters glue valve body and plastic emitting valve body; Described piston rod vertically runs through the described cylinder shell first half; Described spool comprises the first spool and second spool identical with described first spool, and described first spool and described second spool are all connected to described piston-rod lower end and symmetrical along described piston rod; Describedly enter to be provided with the first built-up coil, the second built-up coil, the 3rd built-up coil and the 4th built-up coil in glue valve body, described second built-up coil, described 3rd built-up coil, described 4th built-up coil are all identical with described first built-up coil.
Further, described first built-up coil and described second built-up coil are enclosed within described first spool, described 3rd built-up coil and described 4th built-up coil are enclosed within described second spool, described first built-up coil is connected respectively with bottom described cylinder shell with described 3rd built-up coil, and described second built-up coil is connected with described plastic emitting body top respectively with described 4th built-up coil.
Further, described first built-up coil is made up of O type circle and seal washer, and described O type snare is in described seal washer.
Beneficial effect of the present invention is:
The setting of the first built-up coil, the second built-up coil, the 3rd built-up coil and the 4th built-up coil enhances the sealing in spool and glue-contact face, and avoiding glue to enter in spool affects cylinder operation, causes glue dispensing valve fault.
First built-up coil and the 3rd built-up coil, enhance spool and the sealing entering glue valve body junction valve, effectively prevent the gas spilt from cylinder from entering in glue valve body; When piston rod promotion spool moves up and down, second built-up coil and the cooperation of the first spool, the 4th built-up coil and the second spool coordinate, play unlatching and the closure function of valve, in addition, second built-up coil and the 4th built-up coil enhance the sealing into glue valve body and plastic emitting valve body junction valve, when valve closes, prevent from further flowing into plastic emitting valve body into the glue in glue valve body.
Built-up coil is made up of in seal washer O type snare, and structure is simple, is easy to install, and is convenient to change.
