Technical field
The present invention relates to screw for injection molding machine device, relate in particular to a kind of planet screw head that mixes.
Background technology
Be accompanied by the growing of plastic cement industry, the screw head field that has a very wide range of applications.But the requirement for screw head is also more and more higher, the endoporus of the check ring in current existing master screw head is through-type, mesopore is not to be with mix R groove and pin, screw head stage casing is column type, also not with the pin that mixes, the punishment in advance R slot standard type of screw head front end is three or four punishment in advance R grooves, and standard type meson is do not mix pin and the R groove that mixes, thus existing standard type screw head be do not mix function or the DeGrain that mixes.
Summary of the invention
In view of current screw head above shortcomings, the object of the present invention is to provide a kind of plastics that can make molten condition to interweave fully to mix, the toner diffusion in plastics evenly, the effect of mixing is high and the high screw head of melt index plastics.
For achieving the above object, embodiments of the invention adopt following technical scheme:
A kind of planet screw head that mixes, comprise screw head, check ring and meson, described screw head comprises the R groove two that mixes, latitude annulus, longitude mix R groove and the pin one that mixes, wherein, the described R of mixing groove two is positioned at the front end of described screw head, described latitude annulus is positioned at the punishment in advance position, stage casing of described screw head, described longitude mixes the milling of R groove on described latitude annulus, the described pin one that mixes is positioned at two described longitudes and mixes in the middle of R groove, the interior ring of described check ring comprises latitude R groove, longitude R groove and the pin two that mixes, the points of tangency of described latitude R groove and the described longitude R groove pin two that mixes described in being.
According to one aspect of the present invention, the quantity of described latitude annulus is 1 to 20.
According to one aspect of the present invention, on the external diameter of described meson, have the R of mixing groove one and three, two of the pins that mix to mix in the middle of R groove one be the pin three that mixes.
According to one aspect of the present invention, described in mix R groove one for a plurality of.
According to one aspect of the present invention, described in mix R groove two for a plurality of.
According to one aspect of the present invention, described check ring is fixed, and described screw head can rotate relative to described check ring, in the middle of described screw head mix pin one with shown in together with the pin two that mixes in the interior ring of check ring mixes the material of melten gel state.
According to one aspect of the present invention, the material of described collosol state is plastic cement.
Advantage of the invention process: by changing the shape and structure of screw head, check ring, meson, the plastics that make molten condition are during by meson, check ring, three parts of screw head, interweave and mix fully, reach the toner diffusion making in plastics even, improve the effect of mixing, further improve the melt index of plastics.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the mix structural representation of screw head of planet of the present invention;
Fig. 2 is the structural representation of screw head of the present invention;
Fig. 3 is the structural representation of check ring of the present invention;
Fig. 4 is the structural representation of meson of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, it shows the mix concrete structure of screw head of planet of the present invention, as can be seen from the figure, it comprises screw head 1, check ring 2 and meson 3, described check ring 2 and meson 3 are arranged on the screw rod of screw head 1 through screw head 1 one end, screw head 1 wherein comprises the R groove 2 13 that mixes, latitude annulus 8, longitude mix R groove 7 and the pin 1 that mixes, the R groove 2 13 that mixes is positioned at the front end head of screw head 1, described latitude annulus 8 is positioned at the punishment in advance position, stage casing of screw head 1, longitude mixes 7 millings of R groove on described latitude annulus 8, the described pin 1 that mixes is positioned at the mix centre of R groove 7 of two longitudes.
As shown in Figure 3, it is the structural representation of check ring in the present invention, and the interior ring of check ring 2 comprises latitude R groove 11, longitude R groove 9 and the pin 2 10 that mixes, and latitude R groove 11 is the pin 2 10 that mixes with the points of tangency of longitude R groove 9.
As shown in Figure 4, it is the structural representation of neutretto of the present invention, has the R of mixing groove 1 and the pin 3 12 that mixes on the external diameter of meson 3, in the middle of two R grooves 1 that mix, is the pin 3 12 that mixes.
When screw head of the present invention is used, material is to mix under molten condition, and material comprises plastics, toner etc.The plastics of take now describe as the material under molten condition, first, plastics are by meson 3, the R groove 1 that mixes on meson 3 cylindricals is divided into some equal portions with the pin 3 12 that mixes by plastics, then plastics enter the endoporus of check ring 2, and by the mixing of the latitude R groove 11 on the endoporus of check ring 2, longitude R groove 9 and the pin 2 10 that mixes, make plastics reach certain effect of mixing, in addition on the one hand, check ring 2 is fixing and non-rotary, screw head 1 relatively check ring 2 is rotated, thereby by mixing pin 1 together with the pin 2 10 that mixes in check ring 2 endoporus is fully interweaved the plastics under melten gel state and mixes in the middle of screw head 1, through rotation relatively, plastics are carried out to anastomose and shunting, and then reach the effect of dynamically mixing, plastics are finally by the R groove 2 13 that mixes of screw head 1, arrive the front end of screw head 1, therefore, plastics are by these interleaving process of screw head process of the present invention, finally reach the splendid effect of mixing.
In actual applications, on the external diameter of meson, there are the R of mixing groove 1 and the pin 3 12 that mixes, in the middle of two R grooves 1 that mix, it is the pin 3 12 that mixes, mix R groove 1 for a plurality of, when plastics enter planet and mix screw head, by a plurality of R grooves 1 that mix, plastics are shunted and entered in check ring.
In actual applications, in screw head 1 punishment in advance position, stage casing, be provided with latitude annulus 8, its quantity can be carried out rational spread configuration according to the size of screw head 1, minimum one, can arrange at most 20.Generally, latitude annulus 8 quantity are more, the number of times that plastics mix is just more, and the R groove 2 13 that mixes is at the front end of screw head, is plastics by the mix final unit of screw head of planet, the R groove two that mixes is set to a plurality of, plastics are carried out thinner separately flowing out, the shunting of mixing that interweaves of one-level one-level, the index of melting further gets a promotion, toner more uniform diffusion in plastics, thus the quality of product improved.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, the technical staff of any skilled is in technical scope disclosed by the invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
