Detailed description of the invention
According to hereafter by reference to the accompanying drawings to the detailed description of the specific embodiment of the invention, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present invention more.
Current glue-injection machine all has glue injecting head 100, but for existing glue-injection machine, inventor is in the process used, and glue injecting head 100 of the prior art, after stopping injecting glue, has a certain amount of glue and continues drippage.Through researching and analysing, inventor thinks that the reason producing this phenomenon is, due to the effect of inertia of glue-injection machine glue, when stopping injecting glue, glue can continue motion and go out glue injecting head 100.For this reason, the present inventor proposes following technical scheme:
Fig. 1 is a kind of according to an embodiment of the invention glue injecting head 100 for glue-injection machine, comprises glue head body 20.Especially, in glue head body 20, can glue injection channel be limited with, and the pressure port 21 be communicated with the upper end of glue injection channel, pressure port 21 is configured to be communicated with the pressure apparatus of glue-injection machine, with under the effect of pressure apparatus, makes the upper end of glue injection channel form negative pressure.Particularly, pressure apparatus is configured to open during a Preset Time when stopping injecting glue or after stopping injecting glue, negative pressure is formed to make the upper end of glue injection channel, like this under the effect of external atmospheric pressure, glue effect of inertia and self gravitation effect can be overcome, make glue be positioned at glue injection channel, thus prevent glue from continuing drippage.
In some embodiments of the invention, what glue head body 20 also offers at least one is communicated with glue injection channel enters glue passage, enters glue passage and is communicated with glue feeding tube by the glue feeding opening 25 on glue head body 20.Preferably, the quantity entering glue passage is at least two, and the glue feeding opening 25 on glue head body 20 is also two, is oppositely arranged.Glue injection channel can comprise hybrid chamber 31 and the adhesive pouring nozzle 32 being communicated with hybrid chamber 31.Each enter glue passage be all communicated with hybrid chamber 31.
In embodiments of the present invention, glue injection channel also can comprise the upper cavity 33 being positioned at and being communicated with above hybrid chamber 31 and with hybrid chamber 31, and pressure port 21 is communicated with upper cavity 33.Pressure port 21 is communicated with via this upper cavity 33 with hybrid chamber 31.
In some embodiments of the invention, glue head body 20 also offers the flushing channel that hybrid chamber 31 is communicated with, to clean hybrid chamber 31 and adhesive pouring nozzle 32.Inventor is in the process of research, also find owing to will repeatedly sweep along cleaning agent to clean hybrid chamber 31 with pressure-air in injecting glue process, in this process, a large amount of colloids can be broken through reinforced seal and entered the upper cavity 33 of glue injecting head 100 thus cause a series of problem.The reason producing this phenomenon is, because the space in hybrid chamber 31 is narrower and small, disperse everywhere after gas-liquid mixture and the mixing of residual glue, thus a large amount of colloids can be broken through upper cavity 33 that reinforced seal enters glue injecting head 100, cause the parts damages of glue-injection machine.Inventor passing into air with after making to form malleation in upper cavity 33 in this pressure port 21, when again sweeping along cleaning agent to clean with pressure-air, find that all materials can only spray from the adhesive pouring nozzle 32 of glue injection channel, can ensure that the glue mixed can not be converse to upper cavity 33.By design pressure hole 21 on glue injecting head 100, not only can prevent when stopping injecting glue glue from continuing drippage, and contribute to the cleaning to glue injecting head 100, make to present invention produces unexpected technique effect.
In some embodiments of the invention, as depicted in figs. 1 and 2, glue head body 20 can comprise glue injection part 22, connecting portion 23 and spacer portion 24.Hybrid chamber 31 and adhesive pouring nozzle 32 is limited with in glue injection part 22.Connecting portion 23 is configured to other parts glue injecting head 100 being installed on glue-injection machine, is limited with upper cavity 33 in it.Pressure port 21 can be opened on connecting portion 23.At least one glue feeding opening 25 also can be opened on connecting portion 23, and such as glue feeding opening 25 is two, is arranged on two opposite flanks of connecting portion 23 and (illustrate only the glue feeding opening 25 of side in figure).Spacer portion 24 is arranged between glue injection part 22 and connecting portion 23, it offers the intercommunicating pore being communicated with upper cavity 33 and hybrid chamber 31.Glue injecting head 100 also can comprise agitating device 40, is arranged in hybrid chamber 31, mixes to make at least two kinds of materials entered in hybrid chamber 31.Agitating device 40 is spiral agitator.Having agitating device 40 can make glue injecting head 100 be applied to mixing and glue injection technical field, especially A/B polyurethane adhesive mixing and glue injection field.
The embodiment of the present invention additionally provides a kind of glue-injection machine, and it comprises glue injecting head 100 in above-mentioned any embodiment and pressure apparatus, and pressure apparatus is communicated with the pressure port 21 on the glue head body 20 of glue injecting head 100.Particularly, pressure apparatus is configured to open, to make to form negative pressure in glue injection channel during a Preset Time when stopping injecting glue or after stopping injecting glue.Further, pressure apparatus also can be configured to open when cleaning glue injecting head 100, makes to form malleation in glue injection channel.
In some embodiments of the invention, the connecting portion 23 of glue injecting head 100 can be installed in the travel mechanism of glue-injection machine, drives glue injecting head 100 to carry out injecting glue or encapsulating according to predetermined gluing route to make travel mechanism.Travel mechanism is also provided with and drives the agitating device 40 in glue injecting head 100 to carry out the driving mechanism rotated.Driving mechanism can comprise motor and transmission mechanism, and the rotary motion of motor can be passed to agitating device 40 by transmission mechanism.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present invention is illustrate and described herein detailed, but, without departing from the spirit and scope of the present invention, still can directly determine or derive other modification many or amendment of meeting the principle of the invention according to content disclosed by the invention.Therefore, scope of the present invention should be understood and regard as and cover all these other modification or amendments.
