Specific embodiment

Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure It is fully disclosed to those skilled in the art.

Embodiment one:

Referring to Fig. 1 to Fig. 3, a kind of tubular products inner circle point plastic pin provided by the embodiment of the utility model is shown in figure Head comprising the first end 11 of needle tubing 1 and syringe needle 2, needle tubing 1 connects glue dispensing valve, opposite 12 connecting needle 2 of the second end, Syringe needle 2 is specifically as follows tapered needle, is detachably connected between needle tubing 1 and syringe needle 2, and what formation was connect with needle tubing 1 in syringe needle 2 dissipates Jet stream glue channel 3, scattering gummosis channel 3 extend to the direction of the end of syringe needle 2 21 and form multiple plastic holes 31.

Wherein, referring to Fig. 1 to Fig. 3, needle tubing 1 is specifically as follows the mixing tube of a variety of glue, specifically may include mixing tube With hybrid blade, it is sufficiently mixed A glue with B glue, glue dispensing valve then controls A glue and B glue, and ratio carries out plastic emitting as desired.

Again wherein, referring to Fig. 1 to Fig. 3, the first end 11 of needle tubing 1 forms flaring connection end, carries out with glue dispensing valve Connection.

Specifically, referring to Fig. 1 to Fig. 3, the junction of syringe needle 2 and needle tubing 1 forms scattering gummosis channel 3, syringe needle 2 have with The chock plug 22 that needle tubing 1 connects, the outer wall of chock plug 22 form first slope 221, and the inner wall of the second end 12 is formed and first slope Second slope 121 of 221 cooperations, forms multiple along the circumferentially equidistant of chock plug 22 between first slope 221 and the second slope 121 The plastic emitting channel 222 of arrangement, the end in plastic emitting channel 222 extend to the outer wall of syringe needle 2, and multiple plastic emitting channels 222 constitute scattering Gummosis channel 3.

Specifically, it referring to Fig. 1 to Fig. 3, is carried out a little by 12 semicircle orifices (i.e. plastic hole) being distributed on chock plug circumference Glue A glue and B glue pass through feeler valve according to a certain percentage into glue, and are adequately mixed in mixing tube, then by going out Packing element is flowed out by going out the crack of packing element and plug from 12 semicircle apertures of plug surrounding, and manipulator is by tubular workpiece set Work outside herein, at the uniform velocity extracts out, the dispensing time can be greatly saved in the uniform dispensing of tubular workpiece inner wall, is subsequent The assembling reserved sufficient time.

A kind of tubular products inner circle dispensing needle head provided by the present embodiment, by the scattering gummosis channel of setting, so that Multiple plastic holes can form the uniform plastic emitting at syringe needle, to can make the dispensing of tube-like piece inner wall compared to the prior art more Be it is uniform, guarantee the connectivity robustness of tube-like piece.

Thus, it also has the advantage that compared to the prior art

1) circular pipe workpiece inner circle dispensing problem can not be put by solving common dispensing needle head；
