Description

Independent brush driving mechanism for screw machine

Technical Field

The invention relates to a screw feeder, in particular to an independent brush driving mechanism for a screw feeder.

Background

At present, most screw feeding machines in the industry adopt a roller and brush linkage mode to carry out feeding and screening. At the in-process that the brush swing was sieved the material, the material loading cylinder also can last the operation, leads to the screw to pile up too much and causes the operation unsmooth. Referring to fig. 1, the conventional screw feeder is configured such that a cam 1 'is installed at a driving shaft end of a driving roller, the cam 1' pushes a brush driving shaft 2 'to move upward, and when the cam 1' operates to a low point, the brush driving shaft 2 'is pulled back to the low point by a return spring 3' to move downward. When the motor is running, the roller starts feeding at the same time, which may cause excessive screw accumulation on the rail to form material jamming.
