A kind of emptying type mixing encapsulating head
Technical field
The utility model relates to encapsulating machine field, relates in particular to a kind of head of potting machine that is used in the encapsulating machine.
Background technology
Because the encapsulating machine is to be specifically designed to convection cell control on the existing market; And be used for liquid dropping; Cover; The automated machine that embedding product surface or product are inner, encapsulating machine are divided into one pack system and two component encapsulating machines, and wherein two component encapsulating machines need be realized fully mixing in proportion of two kinds of component fluids could realizing final coagulation result.
Two kinds of liquid independently advance separately on the adhesive dispenser from two groups respectively and enter into hybrid chamber through advancing the control of glue control valve on the head of existing bi-component encapsulating machine, this advance the glue control valve commonly used be needle-valve, also can be path spheres.Two groups of liquid mix the back from the gum outlet plastic emitting in hybrid chamber.Following problem in use appears in this encapsulating machine: the one, and two kinds of liquid residence times are shorter in the hybrid chamber, and degree of mixing is good inadequately, influences adhesivity; The 2nd, hybrid chamber and gum outlet generally right long-pending have the mixing colloid in that not plastic emitting is former, in case for a long time need not, will produce and solidify, have a strong impact on the life-span of encapsulating head.
The utility model content
The purpose of the utility model provides a kind of emptying type mixing encapsulating head that is applicable to the encapsulating machine, and it is good inadequately to solve two groups of liquid mixing degree, and hybrid chamber and gum outlet exist hydrops to influence the technical problem in head of potting machine life-span.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
A kind of emptying type mixing encapsulating head; Comprise that two groups are advanced adhesive dispenser; Advance adhesive dispenser and connect the glue hybrid chamber through advancing the glue control valve; The glue hybrid chamber is communicated with gum outlet, it is characterized in that: in the described glue hybrid chamber stirring vane is arranged, described stirring vane is driven by the stirring motor that is installed in glue hybrid chamber top; Described glue hybrid chamber also is connected with evacuation chamber through the emptying control valve, and described evacuation chamber connects vavuum pump through tracheae.
As a kind of preferred, described emptying control valve is that internal path is 180 degree " I " type path spheres.
As a kind of preferred, described emptying control valve is the electromagnetism on-off valve.
In sum, the utlity model has following beneficial effect:
1, because the utility model has stirring vane in the glue hybrid chamber; This stirring vane is by the stirring motor driving work that is installed in glue hybrid chamber top; Therefore when two groups of liquid get into hybrid chamber; Stirring motor can drive stirring vane and stir the liquid in the hybrid chamber is auxiliary, improves the quality of plastic emitting.
2, the emptying control valve that also is provided with owing to the glue hybrid chamber is connected with outside evacuation chamber; This evacuation chamber connects vavuum pump; Under the effect of vavuum pump, can make evacuation chamber keep vacuum,, then can open the emptying control valve if the encapsulating machine needs long-time the shutdown; Make the mixed liquor that accumulates in hybrid chamber and gum outlet be emptied to evacuation chamber, avoid the obstruction of encapsulating head.

The specific embodiment
As shown in Figure 1; A kind of emptying type mixing encapsulating head comprises that two groups are advanced adhesive dispenser 1, advances adhesive dispenser and connects glue hybrid chamber 5 through advancing glue control valve 2; This advances glue control valve 2 is path spheres, can control the amount that glue gets into glue hybrid chamber 5 through the rotation of controlling this path spheres.Glue hybrid chamber 5 is communicated with gum outlet 6, and stirring vane 3 is arranged in the glue hybrid chamber 5, and this stirring vane 3 is driven through drive link by the stirring motor that is installed in glue hybrid chamber 5 shell upper 4.Therefore when two groups of liquid got into hybrid chamber, stirring motor can drive stirring vane and stir the liquid in the hybrid chamber is auxiliary, improves the quality of plastic emitting.
As shown in Figure 2, glue hybrid chamber 5 also is connected with evacuation chamber 7 through the emptying control valve.This emptying control valve is that internal path is 180 degree " I " type path spheres 8.The cavity top of evacuation chamber 7 also is provided with a pneumatic fitting 9, and this pneumatic fitting 9 can be a quick pipe joint, when tracheae inserts pneumatic fitting 9, just can be used to connect evacuation chamber 7 and vavuum pump.Vavuum pump can vacuumize state to evacuation chamber 7; When the encapsulating machine needs long-time the shutdown; Then can open the emptying control valve; Promptly rotation " I " type path spheres 8 makes that path is communicated with between glue hybrid chamber 5 and the evacuation chamber 7, makes the mixed liquor that accumulates in hybrid chamber and gum outlet under the pull of vacuum effect of evacuation chamber, be emptied to evacuation chamber, avoids the obstruction of encapsulating head.
The utility model: emptying type mixing encapsulating head advance glue control valve and emptying control valve except the path spheres among the embodiment, can also be that application valve body such as solenoid electric valve is realized into glue and emptying control.
