Flour processing vibrating screen

Abstract

The invention provides a flour processing vibrating screen. The flour processing vibrating screen comprises a rack, a screening assembly, a planetary gear set, springs I, a circular ring, protruding parts, telescopic rod assemblies and baffles, wherein a supporting frame in the screening assembly is arranged on the planetary gear set through the springs I, a filter cloth type screen is arranged onthe supporting frame, the circular ring is located below the planetary gear set, the protruding parts are arranged on the upper end face of the circular ring, the telescopic rod assemblies movably installed in the planetary gear set in the axis direction of a revolution component, and the telescopic ends of the telescopic rod assemblies make contact with the bottom of the supporting frame. Through revolution of planet wheels in the planet gear set along the circle center of a sun wheel, when the baffles make contact with the protruding parts, the telescopic ends in the telescopic rod assemblies can be driven to ascend, then the supporting frame can be pushed to ascend, when the baffles break away from the protruding parts, the supporting frame descends, then cyclic rotation can drive thescreening assembly to shake, and the position of the telescopic ends relative to the supporting frame is changed constantly, so that the shaking direction is correspondingly changed, and the vibrationeffect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flour processing, in particular to a vibrating sieve for flour processing. Background technique [0002] In the processing and production of pasta food, the filtering and screening of flour is an essential process. The vibrating sieve uses a vibrating machine to drive the flour to vibrate continuously on the sieve, so that the flour with a smaller particle size passes through the sieve. To achieve the purpose of filtering, and when wheat is used to make flour, it is necessary to remove impurities and sort wheat. During the process of removing impurities and sorting, it is necessary to make the wheat "boiling", and then also need to use a vibrating screen. [0003] Publication No. CN208786878U provides a new type of vibrating screen for flour mills for wheat flour, including a top cover, a sieve box, a base and a shock absorber. The base is fixedly arranged, the shock absorbing device is fixedly arranged ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art uses a motor to drive the vibrating screen to achieve the screening effect, but the vibration frequency and driving position of the motor are fixed, so the vibrating screen only realizes rising and shaking during operation, so it is easy to accumulate when processing materials, resulting in screening not effectively
