Screw extrusion filtering type vacuum kneading machine

Abstract

The invention relates to the field of kneading machine, in particular to a screw extrusion filtering type vacuum kneading machine. The screw extrusion filtering type vacuum kneading machine comprises a base, a main motor, a speed reducer, a gear transmission mechanism and a stirring extrusion mechanism; the main motor is installed at the rear of the base; the front end of the main motor is in driving connection with the speed reducer; the front end of the speed reducer is in transmission connection with the gear transmission mechanism; the front end of the gear transmission mechanism is connected with the stirring extrusion mechanism; the stirring extrusion mechanism is installed at the upper end of the base; the front end of the stirring extrusion mechanism is provided with an extrusion filtering device. The screw extrusion filtering type vacuum kneading machine has the advantages of being compact in design and convenient to use, reducing labor, reducing operation sequences, achieving full-mechanized production, guaranteeing safe production, saving energy consumption and reducing production costs.

Description

technical field [0001] The invention relates to the field of kneaders, in particular to a screw extruding and filtering vacuum kneader. Background technique [0002] The kneader is an ideal equipment for kneading, mixing, vulcanization and polymerization of high-viscosity and elastic-plastic materials. The kneader can be used to produce silicone rubber, sealant, hot melt adhesive, food rubber base, pharmaceutical preparations, etc. At present, the production process is to mix the materials first, then divide the mixed materials manually, and send them to the extruder manually for extrusion molding. It is also necessary to manually press the materials so that the materials can be extruded from the discharge port. Materials that need to be filtered also need to be filtered, and then extruded after filtering. This process requires manual operation. For example, 2 workers are required for the rubber mixing operation, and 3-4 workers are required for the rubber tapping process ...

AI Technical Summary

Problems solved by technology

At present, there is still a problem with some mixing and extrusion machines, that is, during the mixing process, the extrusion screw needs to rotate in reverse, so that the material will not be extruded, so that it can be stirred repeatedly and mixed evenly, but the extrusion screw Reverse rotation will cause a reverse force on the material, which will push the material to the sealing contact position between the end of the screw and the mixing cylinder, which will cause the material to be squeezed out from the seal for a long time, and the seal will be damaged, resulting in the failure of the normal use of the equipment.
