For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of mixing glue spraying head that is used for battenboard PU edge sealing; The mixing glue spraying head body that comprises column extends internally on the end face of mixing glue spraying head body and is provided with air inlet, and extending internally on another end face of mixing glue spraying head body is provided with discharging opening; Air inlet is communicated with discharging opening; Be laid with plural charging aperture on the side face of said mixing glue spraying head body, each charging aperture all is communicated with discharging opening with the place that is communicated with of air inlet at discharging opening, and the cross-sectional area of said air inlet inner segment is less than the cross-sectional area of outer section.
Said air inlet is the little shoulder hole of the outer section big inner segment diameter of diameter.
Said discharging opening is the big inner segment diameter of outer section diameter little shoulder hole, the axis of discharging opening and the dead in line of air inlet.
The diameter of the inner segment of said discharging opening is greater than the diameter of the inner segment of said air inlet.
Described mixing glue spraying head body is the little ladder post of the big two ends of mid diameter diameter, and said charging aperture all is in the major diameter part of the centre of mixing the glue spraying head body.
Be provided with the plane with its parallel axes on the described mixing glue spraying head body in each charging aperture place, the external port that goes out charging aperture is on each self-corresponding plane.
Described charging aperture is two.
The outer peripheral face that said mixing glue spraying head body is provided with an end of air inlet is provided with and is used for the external screw thread that is connected with tracheae.
The outer peripheral face that said mixing glue spraying head body is provided with an end of discharging opening is provided with and is used for the external screw thread that is connected with static mixer.
The inwall of said charging aperture is provided with and is used for the internal thread that is communicated with feed pipe.
The air inlet of the mixing glue spraying head body of the utility model is interconnected with discharging opening and is separately positioned on the two ends of mixing the glue spraying head body; Plural charging aperture is laid on the side face that mixes the glue spraying head body; Each charging aperture all is communicated with discharging opening at the position that discharging opening is communicated with air inlet, because the cross-sectional area of air inlet inner segment is less than the cross-sectional area of outer section, the air inlet bore of air inlet from large to small; Air-flow from the coarse to fine; Make that getting into the flow velocity that mixes the intrinsic gas of glue spraying head accelerates gradually, form low-pressure area, will suck from the raw material of charging aperture at air inlet and discharging opening place; High velocity air is extruded raw material again by discharging opening; Make raw material in time to spray by mixing in the glue spraying head body, prevent that raw material from stopping up glue spraying head, having solved battenboard PU edge sealing of the prior art can't the quantity-produced problem because mix the glue spraying head body to stop up.
