A rubber uniform crushing device

Abstract

The invention belongs to the technical field of crushing machinery, and discloses a uniform crushing device for rubber. The uniform crushing device for rubber comprises a machine body, wherein a firstcrushing bucket, a second crushing bucket and a receiving bucket are arranged in the machine body, a first rotary shaft and a second rotary shaft are rotationally connected in the first crushing bucket, and a crushing roll knife is arranged on each of the first rotary shaft and the second rotary shaft; a third rotary shaft is rotationally connected in the second crushing bucket, and vertical to the first rotary shaft; a sleeve is arranged on the third rotary shaft, a plurality of through holes are formed in the sidewall of the sleeve, and a first shearing knife and a spring are arranged in each through hole; two material-stopping plates are further arranged in the second crushing bucket, a compression spring is arranged between each of the two material-stopping plates and the second crushing bucket, and a second shearing knife is arranged on each material-stopping plate; and a strip-shaped magnet is arranged in each of the first shearing knife and the second shearing knife. The uniform crushing device for rubber solves the problems that the crushed rubber particles are non-uniform in particle size, and the rubber particles with large particle sizes need to be crushed again, so that the crushing time is long, in the prior art.

Description

technical field The invention belongs to the field of crushing machinery, in particular to a rubber uniform crushing device. Background technique Rubber, a highly elastic polymer material with reversible deformation, is commonly used to make tires. Tires are usually installed on metal rims to support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving safety of the vehicle. The quality of tires will directly determine the safety performance of the car during driving. Therefore, the requirements for tire preparation are relatively high, and the rate of defective products in the tire production process is also high. However, in order to reduce the waste of raw materials, defective tires are usually Will be recycled for reprocessing. Tire recycling and reprocessing requires the tires to be shredded into rubber granules, and then the rubber granules are processed into tires. Existing rubber crushing devices usually include ...
