Multi-stage series coaxial wheel type mixing and extrusion device

Abstract

The invention relates to a multi-segment series connection coaxial wheel type mixing extrusion device. The multi-segment series connection coaxial wheel type mixing extrusion device comprises a special-shaped machine barrel, a heat-resisting sealing ring, a conical threaded rod, an extrusion machine head, a first radial bearing set, a second radial bearing set, a third radial bearing set, a hopper, a baffle, a first transmission mechanism, a second transmission mechanism, a first motor, a second motor, a transition gear, a base, a first gear, a second gear, a third gear, a first thrust bearing, a second thrust bearing and a third thrust bearing. The mixing extrusion device is characterized by further comprising a first rotary wheel, a second rotary wheel and a third rotary wheel; a center screw channel set is arranged on a conical wheel of the conical threaded rod, an end face screw channel set is arranged on the left end face of the first rotary wheel, and a first outer circumference screw channel set, a second outer circumference screw channel set and a third outer circumference screw channel set are arranged on screw wheels of the first rotary wheel, the second rotary wheel and the third rotary wheel respectively; the first outer circumference screw channel set, the second outer circumference screw channel set and the third outer circumference screw channel set are sequentially in series connection; the right end of the third outer circumference screw channel set is communicated with the hopper, and the left end of the first outer circumference screw channel set is communicated with the end face screw groove set; the end face screw groove set is communicated with the center screw groove set, and the left end of the center screw groove set is communicated with a through hole of the extrusion machine head; and thus, smashing, grinding, extruding, mixing and conveying passageways for materials are formed. The plastifying performance, the mixing capacity and the grinding and pressing capacity of the device are high, and the plastifying and mixing quality and the yield of the materials are improved.

Description

technical field [0001] The invention relates to a multi-stage series coaxial wheel-type mixing and extruding device, which is used for grinding, mixing, crushing and extruding equipment for various inorganic materials, polymer materials and their fillers, belonging to material crushing, Mixing and extrusion molding equipment technical field. Background technique [0002] In the field of processing rubber, plastics and some inorganic materials, crushing, mixing, grinding, reaction extrusion and extrusion molding are important process links. Ordinary screw extruders have limited functions for crushing, shearing and grinding materials, especially when the materials are subjected to strong grinding, this shortcoming is even more prominent. [0003] In order to overcome the deficiencies of the screw machine, some machines use a disc structure to achieve the purpose of crushing and extrusion. The Chinese patent with the publication number CN03102852 discloses "a disc-type high-s...

AI Technical Summary

Problems solved by technology

[0010] Although the above conical screw extruders have overcome the shortcomings of ordinary screw extruders, they all have the problems of weak plasticizing performance, mixing ability, and grinding and pressing ability, which ultimately affect the quality and efficiency of plasticizing extrusion.
