And a third part 13 is arranged along the circumferential direction of the second part 12, the third part 13 is in a circular ring shape, an external thread structure is arranged on the outer wall surface of the third part, and the arrangement of the external thread structure is convenient for realizing the threaded connection between the glue injection gun head and other structures on the glue injection machine. Optionally, the gun head body 1 is made of copper, and the gun head body 1 made of copper is high in strength and corrosion resistant.
The glue flow passages 2 are arranged inside the gun head body 1, the number of the glue flow passages 2 is multiple, for example, two, three or more glue flow passages can be provided, and the specific number of the glue flow passages 2 is determined according to the number of the component glues to be mixed. At least part of the glue flow channels 2 have different lengths, which specifically means that when the number of the glue flow channels 2 is two, the lengths of the two glue flow channels 2 are different; when the number of the glue flow channels 2 is more than two, the lengths of the glue flow channels 2 may be different, or may be partially the same or partially different. Through setting up many glue runners 2 in rifle head body 1 to make the length of glue runner 2 different, thereby can make the component glue that has different viscosity have even pressure of glue of going out after through different glue runners 2, be favorable to improving the quality of the multicomponent glue that a plurality of component glues mix the formation after going out to glue from the injecting glue rifle head. In this embodiment, since the multi-component glue is formed by mixing the component a glue and the component B glue, two glue flow channels 2 are provided for illustration.
Specifically, in this embodiment, the number of the glue flow channels 2 is two, the two glue flow channels 2 are respectively a first flow channel 21 and a second flow channel 22 which are arranged side by side, the length of the first flow channel 21 is greater than that of the second flow channel 22, the first flow channel 21 is used for flowing the a-component glue with lower viscosity, and the second flow channel 22 is used for flowing the B-component glue with higher viscosity. Optionally, the first flow passage 21 and the second flow passage 22 are both circular holes, and the inner diameter of the first flow passage 21 is larger than the inner diameter of the second flow passage 22. In the present embodiment, the inner diameter of the first flow channel 21 is 4mm, and the inner diameter of the second flow channel 22 is 3mm, although in other embodiments, the shapes of the first flow channel 21 and the second flow channel 22 may also be oval, rectangular, etc., but in order to avoid the component glue remaining, it is preferable to use a circular hole or an oval hole without significant corners and dead corners as the glue flow channel 2. In addition, the aperture of the first flow channel 21 and the second flow channel 22 can be adjusted to other data according to the requirement.
Further alternatively, in this embodiment, the glue flow channel 2 is a straight channel. The glue flow channel 2 is arranged to be a straight line channel, so that the glue flow channel 2 has no corners and dead angles, the component glue residue phenomenon can be avoided to the maximum extent, and the improvement on the flowing smoothness of the component glue is facilitated.
In order to enable component glue to enter and exit the glue flow passage 2, one end of the glue flow passage 2 forms a glue injection hole in the gun head body 1 or on the outer surface of the gun head body 1, and the other end of the glue flow passage forms a glue outlet hole on the outer surface of the gun head body 1. When a glue injection hole is formed at one end of the glue flow channel 2 in the gun head body 1, a connecting channel 3 needs to be arranged in the gun head body 1, so that a glue injection pipeline can inject glue into the glue injection hole through the connecting channel 3; and when one end of the glue flow channel 2 directly forms a glue injection hole on the outer surface of the gun head body 1, the glue injection pipeline can be directly communicated with the glue injection hole, and at the moment, a connecting channel 3 does not need to be arranged inside the gun head body 1.
In this embodiment, in order to improve the stability of the glue injection pipeline during glue injection, a glue injection hole is formed in the gun head body 1 at one end of the glue flow channel 2, and the connection channel 3 is arranged in the gun head body 1. At the moment, the glue injection hole is positioned in the first part 11 of the gun head body 1, and the glue outlet is positioned on the second part 12.
