Abstract

The invention discloses a spiral quantitative feeding device and a stable feeding method. The spiral quantitative feeding device comprises a horizontal spiral conveyor, an automatic feeding adjustment device, a control motor, a drive system, a rotation angle sensor and a single chip microcomputer measurement and control system, wherein the spiral conveyor comprises a spiral shaft, spiral blades, a cylindrical feeding barrel and the like. On one hand, the stable feeding method for the spiral quantitative feeding device reduces the influence on the feeding stability of the spiral feeding device caused by material height change on a storage bin by arranging the automatic feeding adjustment device and eliminates a transient overload phenomenon caused by the extrusion of a material in a spiral material barrel when the device is started next time, on the other hand, the rotating speed and the rotation angle of the motor are controlled by detecting the rotation angle of the spiral shaft by the rotation angle sensor so as to realize accurate quantitative work of the material. The device and the method can be widely used in the transportation, the batching and the packaging production of bulk materials in agriculture, industry, chemical industry and food processing industry.

Description

technical field [0001] The invention relates to a screw quantitative feeding device and a stable feeding method, which belong to the technical field of material conveying devices and can be applied in food, chemical, agricultural and other industries to realize batching production or packaging production of stable quantitative feeding of powder granular materials. Background technique [0002] The screw feeding device has good controllability and stability for the transportation of powder and granular materials, and is widely used in the transportation, batching and packaging production process of industrial minerals, agricultural materials, chemical and food processing raw materials and finished products. The screw feeding device has the characteristics of simple and compact structure, reliable operation, convenient operation and maintenance, and airtight working environment. By controlling the screw rotation speed and time, the feeding amount can be controlled. It is suitab...
