[0002] At present, screw feeder in industry mostly adopts the way of roller and brush linkage to load and screen material. In the process of screening material by brush swing, loading roller also continuously runs, causing excessive accumulation of screw and running disorder. Referring to Figure 1 , the existing screw feeder is by installing a cam 1' at the end of the transmission shaft of driving roller, the cam 1' pushes the brush driving shaft 2' to move upward, when the cam 1' runs to the low point, the brush driving shaft 2' is pulled back to the low point by reset spring 3' to move downward. When motor runs, the roller starts loading at the same time, which may cause excessive accumulation of screw on track and form material jam. SUMMARY
