AI Technical Summary

Technical Problem

Existing rice noodle processing equipment cannot completely separate raw materials with high impurity content or large particle size differences, which easily leads to screen blockage. In addition, the screen plate fixing structure is complicated and inconvenient to maintain, affecting equipment operation and production efficiency.

Method used

A vibrating motor drives the screening shell to vibrate. Combined with an adjustable-angle support screw and a multi-layer screen plate structure, it uses airflow and vibration to separate rice noodles and stones. The screen plate installation is simplified by using a plug-in groove and a clamping handwheel. A transparent observation window and a buffer plate are set to improve separation efficiency and convenience.

Benefits of technology

It achieves efficient separation of rice noodles and stones, reduces screen clogging, improves equipment operating efficiency and maintenance convenience, and increases production efficiency.

Abstract

The utility model discloses a raw material stoning machine for rice noodle processing. The raw material stoning machine comprises a rack, a feeding barrel, an air suction barrel, a screening shell, an upper screening plate, a lower screening plate, a pressing hand wheel, a vibration motor and a supporting lead screw. The vibration motor is used for driving the screening shell to vibrate; the feeding barrel is used for feeding rice flour into the screening shell, the bottom of the air suction barrel is communicated with the containing cavity, the upper screening plate and the lower screening plate are obliquely arranged in the screening shell in parallel, the pressing plate abuts against the back of the upper screening plate and the back of the lower screening plate, and the pressing hand wheel is used for adjusting the pressure applied by the pressing plate. The vibration motor can drive the screening shell to vibrate, so that rice flour and stones jump and are layered on the screening surface, light rice flour suspends on the upper layer under the action of airflow and slides downwards to be discharged, and heavy stones gradually move upwards to a high-position stone discharging opening to be discharged; a user adjusts the pressure of the pressing plate by rotating the pressing hand wheel, so that the upper sieve plate and the lower sieve plate are rapidly fixed and prevented from loosening in vibration, and the operation efficiency and the maintenance convenience are effectively improved.
