Abstract
The present invention relates to a calendering head device for an extrusion cylinder of an injection machine, which is characterized in that the present invention is composed of a calendering rotor which can be butted with a screw rod, and a calendering sleeve which can be butted with the outlet end of a feed barrel, wherein the calendering sleeve is movably sheathed with the calendering rotor and pits which are interlaced backwards and forwards are equably distributed on the circumambient wall of the calendering rotor and the inner circumambient wall of the calendering sleeve. The slippage of the pits arranged on the outer wall of the calendering rotor or on the inner circumambient wall of the calendering sleeve causes the still pits of the calendering sleeve and the steel cutting edges of the pits of the calendering rotor to form shearing, and because the pits are equably distributed on the surfaces of the calendering sleeve and the calendering rotor, a plurality of shearing edges are formed. The shearing edges can cut melting tremellose plastics in the feed barrel in a multiple channel method, and thus, improving the calendering capability of the distribution and the dispersion of the tremellose plastics. The present invention can be combined with the existing screw rod type feed barrel extruding machine, can improve the plasticizing quality and the output of the injection machine and is especially suitable for processing moulding products with more additives.
Description
Technical field
What the present invention relates to is the injection machine recipient, especially a kind of mixing mechanism of injection machine recipient.
Technical background
Injection molding machine of plastic is an industrial circle equipment commonly used, and they comprise: injection machine, inflation film manufacturing machine, plastic granulator machine, plastic cement ginseng look machine, plastic cement reclaiming machine.With the extrusion cylinder mechanism of extruding after the raw material mixing is the important component part of the said equipment, the pressing mechanism of injection machine is made up of barrel and the screw rod that sets within it usually, its course of work is: plastic raw materials constantly enters barrel, by the screw rod that rotates the graininess plastic raw materials is pushed and to be moved forward, be subjected to the heating of the peripheral electric heater unit of barrel, graininess plastics in the barrel are dissolved agglutination, and molten refining under the screw acting that rotates, be injected into different die cavity rush at the extrusion of barrel with the spiral line after.This shows that the performance quality of pressing mechanism can directly influence the plasticizing quality and the output of injection machine.For this reason, people are carrying out various improvement and trial around the shape of screw rod, attempt to improve by the improvement to screw rod the performance of pressing mechanism.As three-stage screw, exactly screw rod is divided into feeding section, compression section and metering section, the molten refining of strengthening gluey plastics in the barrel by the sudden change or the gradual change of core diameter of thread on the screw rod.But because it still rests on the extrusion process between molten material, therefore, its molten refining effect still can not reach fully and be complete.
Summary of the invention
The objective of the invention is deficiency, a kind of plasticizing quality and output that can improve injection machine greatly is provided, be applicable to the mixing head device of injection moulding muchine extrusion cylinder that various pressing mechanisms are equipped at above-mentioned existence.
Mixing head device of injection moulding muchine extrusion cylinder of the present invention is characterized in that: be made up of a mixing rotor that can dock with screw rod and a mixing cover that can dock with the barrel port of export, mixing cover and mixing rotor activity are nested; Mixing rotor perisporium and mixing cover internal perisporium are evenly equipped with the pit that anteroposterior position interlaces respectively.
The design principle of mixing head device of injection moulding muchine extrusion cylinder of the present invention is: throw off the improved thinking of screw rod, utilization is arranged on the mixing rotor outer wall pit or the mutual changing of the relative positions of mixing cover internal perisporium pit, make to form between the rigidity cutting edge of mixing rotor pit of static mixing cover pit and rotation and shear, because therefore mixing cover and mixing rotor surface are uniform multiple tracks pit has formed numerous sheared edges.These sheared edges can be to fusion in the barrel gluey plastics carry out the multiple tracks cutting, thereby improve distribution and dispersion milling ability to gluey plastics.
Mixing head device of injection moulding muchine extrusion cylinder design science of the present invention, rational in infrastructure, simple, it is used in combination with existing screw barrel extruder, can improve the plasticizing quality and the output of injection machine greatly, is particularly useful for the high system of the moulding product processing of additive level.
The concrete structure of mixing head device of injection moulding muchine extrusion cylinder of the present invention is provided in detail by the following drawings and embodiment.

Fig. 3 is the mixing nested structure schematic diagram of mixing head device of injection moulding muchine extrusion cylinder shown in Figure 1;
Fig. 4 is the another kind of structural representation of mixing cover of mixing head device of injection moulding muchine extrusion cylinder shown in Figure 1;
Fig. 5 is that mixing head device of injection moulding muchine extrusion cylinder uses structural representation.
The specific embodiment
Embodiment 1: can be clear that from Fig. 1 mixing head device of injection moulding muchine extrusion cylinder is made up of a mixing rotor 1 that can dock with screw rod and a mixing cover 2 that can dock with the barrel port of export, mixing rotor 1 is plugged in the mixing cover 2,2 in mixing rotor 1 and mixing cover can relatively rotate, be evenly equipped with hemispherical dimples 11 (see figure 2)s around mixing rotor 1 perisporium, an end of mixing rotor 1 is provided with and is used for the screw 12 that it is connected with the screw rod end.Described mixing cover 2 internal perisporiums are provided with multiple tracks annular groove 21 (see figure 3)s, and an end of mixing cover 2 is provided with its thread head 22 that docks with the barrel port of export.The hemispherical dimples 11 that is arranged on the mixing rotor 1 interlaces with groove 21 front and back positions that are arranged on mixing cover 2 internal perisporiums.
The operation principle of this mixing head device of injection moulding muchine extrusion cylinder is seen Fig. 5: this mixing refining head device is docked with the injection machine recipient, and the mixing rotor 1 of mixing refining head device can rotate synchronously with screw rod.In the barrel 3 fusions gluey plastics through after the stirring of screw rod 4, promptly be squeezed into the mixing rotor 1 perisporium pit 11 or the mixing cover 2 internal perisporium grooves 21 of mixing refining head device, rotation along with screw rod 4, mixing rotor 1 is delivered to the gluey plastics in its perisporium pit 11 in the mixing cover 2 internal perisporium grooves 21 in rotary course, because mixing rotor 1 perisporium pit 11 or mixing cover 2 internal perisporium grooves 21 are staggeredly located and have relative motion, thereby cause the gluey plastics in this transmittance process will be by continuous cutting-off and continuous mixing again, as shown in Figure 1, gluey plastics are pressed between the groove 21 of the pit 11 of mixing rotor 1 and mixing cover 2
Direction is transmitted (see figure 1) successively, and its mixed performance is also along with the number of repetition of these processes forms doubly increase.
Embodiment 2: the basic structure of mixing head device of injection moulding muchine extrusion cylinder is identical with embodiment 1, difference is: mixing cover 2 internal perisporiums are evenly equipped with hemispherical dimples 23, and the hemispherical dimples 11 on the mixing rotor 1 interlaces with hemispherical dimples 23 front and back positions that are arranged on mixing cover 2 internal perisporiums.
Its operation principle is identical with embodiment 1.
