Abstract

The utility model discloses a tetramerus synchronous rotor calendaring chamber of plastic pressure kneading machine which solves the problems that the rotor structure in the prior calendering chamber is two-edged, the transmission is asynchronous, the efficiency is low during the calendering, the materials are unevenly distributed and the unit energy consumption is high. The lower end of an upper top bolt in the calendaring chamber takes the shape of an inverse hill character; each rotor is provided with four prisms, namely two long prisms and two short prisms. The utility model has the advantages that the capability of receiving materials is strong; the shearing to the materials is enforced, and the upper top bolt taking the shape of the inverse hill character is adopted, so the storage dead angle is avoided and the dispersion of the materials and the simple mixing are improved. The synchronism of the two rotors ensures the discharged materials have an evenly distributed temperature and almost same physical performance and rheological performance on all points. With the improvement of the shearing, the calendaring time is shortened, the production efficiency is improved, and the unit energy consumption is decreased.

Description

The mixing chamber of plastics pressure initial refining machine four rib synchronous rotors

(1) technical field:

The utility model is the mixing chambers of a kind of plastics adding pressure type kneading four rib synchronous rotors.

(2) background technology:

Rotor structure in the mixing chamber of existing plastics pressure initial refining machine is digonous, and transmission is asynchronous, and efficient is low in mixing process, and material disperses uneven, the specific energy consumption height.

(3) summary of the invention:

The purpose of this utility model is to solve above-mentioned existing problem, provides a kind of and can change the refinement mode, raises the efficiency, and increases the material dispersiveness, reduces the mixing chamber of plastics pressure initial refining machine four rib synchronous rotors of specific energy consumption.

The present invention is achieved in that the bottom of the floating weight in mixing chamber is the font of falling the mountain; Each rotor has four rib bodies, i.e. two long rib bodies, two short rib bodies.

The utility model has the advantages that: 1, owing to the phase relation that is fit to, the similar a pair of roller of two rotors, thereby the material feeding ability is strong; 2, because the appropriate arrangement between the rib of two rotors to the shearing enhancing of material, has been adopted the font of falling mountain floating weight simultaneously, remove the material stock dead angle, strengthened material dispersed and simple immixture.3, two rotors are synchronous, thereby make the material temperature of discharging be evenly distributed, and everywhere physical property and rheological property are of slight difference.4, because shear action strengthens, shorten mixing time, enhanced productivity, reduced specific energy consumption.

(4) description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is 2 synchronous rotor profile outlines;

Fig. 3 is that synchronous rotor rib body is arranged expanded view;

(5) specific embodiment:

Describe in detail below in conjunction with accompanying drawing: as shown in the figure, the bottom of the floating weight 2 in mixing chamber 1 is the font of falling the mountain; Each rotor 3 has four rib bodies, i.e. two long rib bodies, two short rib bodies; The speed ratio of two rotors is 1: 1.

During work, the font of falling mountain floating weight 2 drives to rise by vapour and puts in place, opens gallery ports, main electric motor starting, two synchronous rotors 3 rotate relatively, after the end that feeds intake, the font of falling mountain floating weight puts in place for 2 times, closes gallery ports, and instrument such as the observation scheduled time or temperature show, after reaching technological requirement, the word of falling mountain floating weight 2 rises and puts in place, and mixing chamber 1 is by the switching mechanism 140 ° of dischargings of tumbling, discharging finishes, by switching mechanism, original position is got back in mixing chamber 1, carries out next process work.
