Summary of the invention
The utility model mainly provides a kind of can in time the unlatching and the closed glue rifle glue-spraying spout of beating, is sealing existing technical problem when welding crack to solve present stage with beating the glue mode.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of glue rifle glue discharging mouth of beating comprises: rifle pin, rifle cap, and described rifle pin is divided into shank section and needle point section, and the afterbody of bar is provided with screw thread.The needle point section is divided into cylinder part and circular cone body, and circular cone body cone tip part is designed to the spanner otch.Described rifle cap divides spanner otch section and thread segment, and two sections coaxial, and axially extending bore is opened at described rifle cap center, and described rifle pin circular cone body inserts axially extending bore from described rifle cap thread section end face.Screw thread is set rifle pin shank afterbody and the sharp spanner otch that is designed to of awl can allow the rifle pin being connected between the glue rifle control system interface not only stablizing firmly but also make the transposing of rifle pin very convenient with whole beating.Rubber-storing cylinder during thread segment on the same rifle cap can make the rifle cap and beat glue rifle high-pressure system is connected, and spanner otch Duan Ze being threaded to strengthen both bonding strengths between rifle cap and the rubber-storing cylinder that be used for screwing up with a wrench is set on the rifle cap.Rifle pin needle point section be arranged to cone and rifle cap center open axially extending bore and rifle pin needle point section insert the axially extending bore of rifle cap then can make both form glue-spraying spout and by change rifle pin and the relative position of rifle cap control the unlatching of rifle mouth and closure and gel quantity how much.
As preferably, described rifle pin needle point section cone base diameter is greater than described rifle cap through-hole diameter, 10 °＜A of described rifle pin needle point section circular cone body cone angle＜15 °.The cone of rifle pin bottom is straight toward greater than rifle cap axially extending bore diameter, has guaranteed that the rifle pin inserts behind the rifle cap can form the rifle mouth between the needle point conical surface and rifle cap axially extending bore inwall.Gel quantity what by the gap decision between rifle pin needle point section cone surface and the rifle cap axially extending bore inwall, cone angle is excessive cause the rifle pin at certain stroke lower cone the excesssive gap between the surperficial and rifle cap inwall, be difficult to control the glue amount of glue discharging mouth.
As preferably, described rifle cap inwall and thread segment end face intersection are provided with arc transition.Through-hole wall and rifle cap thread section end face intersection adopt arc transition can effectively reduce the damage that the rifle mouth causes the surface owing to the mutual bump between rifle pin and the rifle cap when unlatching and closure.
Eventually the above, the utility model improves the existing glue rifle gun mouth structure of beating, by rifle pin stretching back and forth in the rifle cap, the unlatching that has realized the rifle mouth is with closed, rifle mouth spray glue is in by state (closure or openness) decision of rifle mouth, solved dexterously to beat that the glue rifle is exerted pressure and there is nonsynchronous technical problem in plastic emitting in spray glue process.
