Description
Technical field
Automatic dispensing machine field is the utility model is related to, more particularly, to a kind of screw rod glue dispensing valve.
Background technology
It is commonly used with glue, the demand of spot gluing equipment more extensively and variation, the requirement to spot gluing equipment
More and more higher, at present, the automatic dispensing machine that in the market occurs use independent dispensing controller more in plastic emitting control aspect, mainly
It is divided into two classes：Syringe plastic emitting and glue dispensing valve plastic emitting.Syringe according to volume size have successively 3ml, 5ml, 10ml, 30ml, 50ml,
300ml, 330ml etc., its mode of action are that have dispensing controller to control the inflation/deflation of syringe, plastic emitting after inflating pressure, row
Stop glue after gas pressure release, dispensing machinery hand can generally be coupled, switch controlling signal is sent by manipulator to control plastic emitting.Glue dispensing valve control
Glue mode is totally divided into two kinds：That is firing pin type and resorption type, Main Basiss manner of execution, when close glue action, valve element is past
The mode that gum outlet is blocked in preceding action is firing pin type, generally directed to low viscosity glue；Resorption type valve i.e. carry out close glue action when,
It is resorption type that valve element acts and blocks the mode at glue inlet end backward, generally directed to the glue that viscosity is higher.And both of which is by rear
Portion's pressure promotes plastic emitting, without metering unit.
The weak point of above-mentioned two classes plastic emitting mode is respectively.During syringe plastic emitting, due to the compressive characteristics of air, lead
Cause switch glue time lag, that is, when coming unglued can not horse back plastic emitting, close glue be to stop immediately, and its with packing element air hold
Long-pending change Slack time changes therewith, when the more big this phenomenon of air volume is obvious all the more, also has and is reduced using certain methods
It influences, such as：Reduce air tubing length, overstriking tracheae, increase air valve latus rectum etc., but a part can be improved at most, in principle
Its plastic emitting shakiness is determined.Comparatively speaking, controlled using glue dispensing valve, time-delay can be avoided, but work as some glue pair
Temperature is more sensitive, such as epoxy glue, and the height of temperature is very big on the influence of its mobility, when pressure measuring cylinder bestows same pressure, because
Viscosity B coefficent plastic emitting speed difference is very big, therefore more difficult accurate plastic emitting；Some glue are volatile or easily deposit wall built-up, now passage
Resistance changes therewith, and plastic emitting flow velocity also can not control；And existing glue dispensing valve easily has bubble at gum outlet so that
Glue drop does not come out.
Utility model content
In view of this, technical problem to be solved in the utility model is：There is provided a simple in construction and can realize out
Glue speed can quantified controlling, glue dispensing valve be easy to exclude the screw rod glue dispensing valve of bubble, plastic emitting not water clock.
In order to achieve the above object, the utility model adopts the following technical scheme that to realize：
A kind of screw rod glue dispensing valve is (also known as：Screw rod measures glue dispensing valve), including valve body, the valve body top is equipped with electricity
Machine, the valve body is interior to be provided with the screw rod for connecting the motor, and the screw jacket is equipped with the stator for being fixed on valve body, described
Stator sleeve is set with outside stator, valve body is fixed in the stator sleeve threaded connection, and the middle section of the valve body is flexibly connected
Feeding device, the front end of the valve body are provided with gum outlet；Motor connection integrated with screw rod, ensure that rotating zero clearance reduces mistake
Difference；
The rotation of motor driven screw rod, screw rod glue dispensing valve match somebody with somebody hop controller, and the number of turns rotated by motor can be accurate
Calculate gel quantity.
Further, the motor top is provided with motor rotating disk, and the motor rotating disk is provided with and stirs groove；Motor translator turns
Disk, can intuitively observe motor operating state, also can manual toggle motor rotating disk test screw rod glue dispensing valve plastic emitting state.
Further, the motor is Pulse Width Control motor；Motor driven screw rod rotates, gel quantity needed for strict control,
It is high using pulse control mode, plastic emitting precision；The rotating speed of motor is controllable and has positive and negative rotating function, ensures plastic emitting effect not water clock.
Further, the feeding device is provided with feeding mouth, and the feeding mouth connects the stator.Feeding device activity is even
Be connected to valve body, achievable feeding mouth can 360 degree of Arbitrary Rotations, be easy to screw rod dispensing valve exhaust operation.
Further, sealed between the screw rod and the stator；Ensure plastic emitting effect not water clock.
Further, the upper end of the stator sleeve of the valve body is provided with nut, the external diameter of the nut and general syringe point
The syringe external diameter of glue is consistent, is easy to replace syringe operation.
Further, the upper end of the stator sleeve of the valve body is provided with nut, the external diameter of the nut and general syringe point
The syringe external diameter of glue is inconsistent.
As shown from the above technical solution, the beneficial effects of the utility model are：
The rotation of motor driven screw rod, the number of turns rotated by motor can accurately calculate gel quantity, and plastic emitting is accurate；
Feeding mouth can realize that screw rod dispensing valve exhaust operation is easy in 360 degree of rotations；Motor translator rotating disk, it can intuitively observe operation shape
State, also can manual toggle test screw rod glue dispensing valve plastic emitting state.
