Rubber and plastic plasticizing and toughening machine

Abstract

The invention relates to the field of rubber and plastic machining and aims to provide a plasticizing and toughening machine for rubber-plastic materials. The plasticizing and toughening machine for the rubber-plastic materials comprises a machine frame and further comprises a plasticizing and toughening device and a filtering device. The filtering device comprises a rotary disc base with a round cavity, rotary discs which are located in the round cavity and provided with a plurality of filtering hole sets uniformly distributed in the circumferential direction and a rotary disc driving device connected with the machine frame; the rotary disc base is provided with a plurality of through holes corresponding to the filtering hole sets in a one-to-one correspondence mode; the rear ends of the first through holes communicate with the outlet end of the plasticizing and toughening device; and the rear ends of the other through holes are each provided with a through cover which is provided with an air inlet valve and connected with the rotary disc base. The rubber-plastic materials prepared through the plasticizing and toughening machine are small in impurity and good in toughness. Impurities mixed in the rubber-plastic materials are filtered through the filtering hole sets so that the purity degree can be further increased. The multiple filtering hole sets are used alternately, the filtering hole sets which are not in using positions are cleaned through compressed air, and thus the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of rubber and plastic processing, in particular to a plasticizing and toughening machine for rubber and plastic. Background technique [0002] The invention of Chinese patent application number CN201310170828.7 discloses a plasticizing device, which includes a motor, a transmission device, a transmission shaft, a plasticizing front plate supported on the front end of the transmission shaft by a deep groove ball bearing, and a plasticizing front plate supported by a self-aligning roller bearing. On the plasticized rear plate at the rear end of the drive shaft, the plasticized rear plate extends upwards to have a motor fixing plate for fixing and installing the motor. The front end of the motor is provided with a positioning boss for fixing. The transmission device includes a small pulley fixedly installed on the output shaft of the motor, a large pulley fixedly installed on the transmission shaft, and a timing belt con...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages that the rubber and plastic impurities produced by the current plasticizing device use waste rubber and plastic as raw materials and have poor toughness, and to provide a rubber and plastic material with less impurities and less toughness. Good rubber and plastic plasticizing and toughening machine
