Abstract

The invention relates to the technical field of rubber processing equipment, and discloses an efficient rubber plastifying device. The device comprises a box body, wherein a crushing box is fixedly connected to the top of the box body, two sets of rotating shafts are rotationally installed in the crushing box, crushing rollers are fixedly installed on the outer sides of the two sets of rotating shafts respectively, one end of each rotating shaft penetrates through the side wall of the crushing box and is fixedly provided with a chain wheel, and the two chain wheels are in transmission connection through a conveying chain. A transmission shaft is rotationally installed at the top of the box body, a plurality of discharging holes are formed in the top of the box body and annularly distributed around the transmission shaft, a rotating plate is fixedly installed at the upper end of the transmission shaft, the bottom end of the transmission shaft extends into the box body, a large gear is fixedly installed at the bottom end of the transmission shaft, and a plurality of through grooves are formed in the middle of the large gear. Crushed rubber particles are sequentially scraped off from the discharging holes and the through grooves through rotation of the rotating plate, discharging is quantitatively controlled, scattering is avoided, and the plastifying efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of rubber processing equipment, in particular to a high-efficiency rubber plasticating device. Background technique: [0002] Mastication refers to a process of rubber processing, which refers to the use of mechanical or chemical methods to reduce the molecular weight and viscosity of raw rubber to improve its plasticity and obtain appropriate fluidity to meet the needs of further processing of mixing and molding. The plasticating process is a process in which the rubber macromolecular chain is broken, and the molecular chain is changed from long to short to make the molecular weight distribution uniform. There are two main factors that lead to the breakage of macromolecular chains in the plasticizing process: one is mechanical destruction; the other is thermal oxidative degradation. During low-temperature mastication, it is mainly due to mechanical destruction, and macromolecules undergo chain scission un...
