[0002] A screw feeder is a mechanical device that uses rotating spiral blades to transport materials upward. It is widely used in the chemical, food, building materials and other industries. It is mainly used to transport powdered, granular or small block materials from low places to high silos, hoppers or equipment. Its working principle is based on the spiral rotation driving the material forward. The motor drives the spiral blades to rotate, so that the material moves forward with the blades and finally reaches the discharge port of the equipment. However, due to the material conveying, the screw feeder often produces large vibrations when the motor-threaded conveying shaft rotates. Long-term use will cause the conveying shaft and the frame to not fit together, affecting the feeding efficiency, and there may be a situation where the material overturns.
