The invention discloses a permanent magnet drive same-direction meshing-type rotor internal mixer which mainly comprises a power device, a transmission device, a feeding-pressurizing mechanism, an internal mixing device and an intelligent control device, wherein a permanent magnet synchronous alternating-current motor capable of achieving the low rotational speed and the high torque is adopted asthe power device; an eccentric upper jacking bolt is adopted by the feeding-pressurizing mechanism to control a feeding port, so as to resolve the feeding difficulty; the air cylinder control is adopted for the lifting of the upper jacking bolt as well as the mold opening and closing of an internal mixing room; a front-rear combined detachable plate-type structure is adopted by the internal mixingroom; a drill hole flow cooling means is adopted for the middle of the internal mixing room; the internal mixing device comprises the internal mixing room and synchronous same-direction meshing-typerotors; the PLC control is adopted by the intelligent control device; and accordingly, the parallel operation of intelligent programmed automatic mixing and manual mixing can be achieved. By adoptionof the permanent magnet drive same-direction meshing-type rotor internal mixer disclosed by the invention, the mixing efficiency and quality can be greatly improved, the circumstances of material leakage and non-uniform mixing can be reduced, and the elongational flow of a rubber material can be improved.

Description

technical field [0001] The invention relates to the field of internal mixers, in particular to a permanent magnet driven co-direction meshing rotor internal mixer. Background technique [0002] Internal mixer is a commonly used polymer processing machine in the field of rubber and plastic machinery and equipment, especially in the processing of composite materials, improved masterbatches, and rubber products. It is the best and indispensable mechanical equipment at this stage. However, there are some shortcomings in the internal mixer at this stage. The internal mixer is intermittent mixing, and the working process requires uninterrupted parking, unloading, cooling, loading, etc., so the production efficiency is low; because the internal mixer cannot be absolutely sealed , It is easy to cause powder materials such as carbon black to fly, which seriously pollutes the working environment and damages the health of the operator of the internal mixer; and the internal mixer mixes...

Problems solved by technology

In the article, the mixing mechanism and experimental research of the same speed and the same direction rotor internal mixer, the mixing mechanism of the same speed and the same direction rotor is deeply studied. In the process, the internal mixer platform for the test was developed and carried out. According to the corresponding experimental research, the mixing mechanism of "shear-extrusion-stretch three-mechanical comprehensive action" was proposed, and the shear and extrusion compactness of the rubber was analyzed when the rubber was in the elastic and viscoelastic "like solid state". The effect of compounding on rubber mixing, and the meshing characteristics of co-rotating twin-screw rotors In this paper, through the analysis of the motion of a pair of rotors rotating in the same direction, applying the principle of meshing, the meshing characteristics of the rotor profile are obtained, and the screw is discussed. However, none of the above documents discloses the favorable influence of the rotor on the silanization reaction of silica rubber at a certain angle, so that it can adapt to heat-sensitive materials and high-speed mixing processes, and improve the internal mixing process. The technical solution for the feeding capacity and mixing effect of the machine; and it does not solve the problem that the general shearing rotor heats up quickly, and the shearing efficiency of the meshing rotor is low. Most meshing rotors can only rotate in opposite directions, otherwise interference will occur technical issues
