Abstract
The utility model relates to a five-screw rod extruding machine, wherein the five screw rods are divided into an upper conjugate set and a lower conjugate set, one screw rod is centered and is jointly used for the upper conjugate set and the lower conjugate set, and every two of the other four screw rods are regarded as one set to be respectively and symmetrically arranged above and under the screw rod. Due to six meshing regions, the five-screw rod extruding machine is better in flow bypassing effect and more in cutting process, i.e. is better in distributing mixture and spreading mixture. As for the five-screw rod extruding machine, the times for cutting the material are manyfold higher compared with a double-screw rod extruding machine, each component of the material can be easily homogenized and palletized, and the material on a plurality of layer surfaces in space can abundantly switch and flow, thus achieving a good plastifying and spreading effect; in addition, stable charging and conveying of the material can be guaranteed, and the five-screw rod extruding machine is applied to various extruding equipment for machining the plastic.
Description
Technical field
The utility model belongs to the plastic processing machinery field, particularly relates to a kind of extruder, specifically a kind of five screw extruders.
Background technology
Along with the continuous development of modern plastic cement industry, the extensive use of especially high filling, high dispersive material, and to improving constantly that aspects such as low energy consumption require, the rubber and plastic process equipment develops to diversification, multiscrew direction gradually.But at present in the plastics field that is mixed, the extruder that generally uses is the parallel double-screw formula, its transmission is parallel two shaft types output, and the double-screw type extruder of this quasi-tradition has only one because of its region of engagement, therefore the mobile exchange rate of material is low relatively, participation plastifies, mixing rate is low, thereby influences the performance of finished product material.
The utility model content
The technical problems to be solved in the utility model; be to overcome above shortcomings in the prior art; a kind of five screw extruders with good plasticizing dispersion effect are provided; its five screw rods arrangement mode makes the region of engagement increase to six; this extrusion system has better shunting effect and shear history more frequently with respect to the traditional double screw extruder; that is to say that having better distribution mixes and disperse mixing; the shearing number of times that material stands therein will be higher than twin-screw exponentially; each component is easy to obtain homogenising and micronize; material is fully exchanged on a plurality of aspects in space; flow; reach good plasticizing dispersion effect, also can guarantee in addition to feed in raw material and carry highly stable.
For solving above-mentioned technical problem, the technical scheme that the utility model adopted is as follows:
A kind of five screw extruders, its special feature are that the screw rod quantity in its screw-rod structure is five, and described this five screw rods branch has upper and lower two conjugation groups; Wherein a screw rod is placed in the middle, for two conjugation groups are shared up and down; All the other four screw rods are located at two by one group its top, below respectively symmetrically,
Screw rod placed in the middle is formed with the two screw rods of its top and is gone up the conjugation group, the equilateral triangle distribution that their axle center is down, and the screwing element on each screw rod meshes with the screwing element conjugation of other two screw rods respectively;
Correspondingly, screw rod placed in the middle is formed conjugation group down with the two screw rods of its below, and their axle center is equilateral triangle and distributes, and the screwing element on each screw rod meshes with the screwing element conjugation of other two screw rods respectively.
Described five screw rods are driven by the output shaft of decelerator, and described output shaft is corresponding one by one with five screw rods.
The utility model is owing to adopted above-mentioned structure; it compared with prior art; obtained technological progress is: screw rod placed in the middle is for the conjugation group is shared up and down; extrusion system has six region of engagements; compare a region of engagement of traditional double screw-type extruder; have better shunting effect and shearing more frequently; promptly have better distribution and mix and disperse mixing; the shearing number of times that material stands therein will be higher than twin-screw at double; each component is easy to obtain homogenising and micronize; material on a plurality of aspects in space fully exchange flow, reach good plasticizing dispersion effect, reinforced and carry also highly stable.The utility model is suitable for the extrusion equipment of doing various plastic processings.
The utility model below in conjunction with Figure of description with and the specific embodiment be described in further detail.
Description of drawings
Fig. 1 is a radially-arranged structural representation between the screw rod of five screw extruders of the utility model embodiment.
Among the figure: 1-5 is respectively screw rod, and 12-52 is screwing element (shadow region is represented).
The specific embodiment
Embodiment
A kind of five screw extruders, the screw rod 1-5 quantity in its screw-rod structure is five.
As shown in Figure 1, this five screw rod 1-5 divides upper and lower two conjugation groups; Wherein a screw rod 3 is placed in the middle, for two conjugation groups are shared up and down; 1,2,4,5 two one group of all the other four screw rod ground (as among the figure 1 and 2 one group, 3 and 4 one groups) be located at top, the below of screw rod 3 placed in the middle respectively symmetrically.
Screw rod 3 placed in the middle is formed with the two screw rods 1,2 of its top and is gone up the conjugation group, and the equilateral triangle that their axle center is down distributes, and the screwing element 12-32 on each screw rod 1-3 meshes with the screwing element conjugation of other two screw rods respectively;
Correspondingly, screw rod 3 placed in the middle is formed conjugation group down with the two screw rods 4,5 of its below, and their axle center is equilateral triangle and distributes, the screwing element 32-52 on each screw rod 3-5 respectively with the screwing element conjugation engagement of other two screw rods.
Five screw rod 1-5 are driven by the output shaft of decelerator, and output shaft is corresponding one by one with five screw rod 1-5.
The structure of other parts of present embodiment is identical with extruder of the prior art.
