A raw material screening device for producing sedimentary silicone rubber with good anti-blocking effect

Abstract

The utility model discloses a kind of raw material screening devices with good anti-blocking effect for precipitated silica rubber production, comprising: screening machine box, the screening machine box includes shell, the top of the shell is communicated with feed hopper, the bottom of the shell is provided with material receiving box, support seat, the support seat is set in the bottom of shell, anti-blocking mechanism, the anti-blocking mechanism includes motor, the motor is fixedly connected at the back of shell, the output end of the motor is fixedly connected with transmission frame, the top and bottom of transmission frame inside are slidably connected with push rod. The utility model is through the synergies of motor, transmission frame, push rod, plugging slide plate, cleaning cylinder, gear one and toothed plate in anti-blocking mechanism, so that cleaning cylinder can realize movement and rotation simultaneously, can clean screen in an all-round way, effectively avoid precipitated silica rubber raw material to block screen, reduce cleaning frequency of shutdown, improve screening efficiency, guarantee production continuity.
