BAND-SAW CLEANING MECHANISM FOR BAND SAW MACHINE

摘要

A band-saw cleaning mechanism includes a cleaning unit having a steel brush, a first motor having a driving shaft, and a linking rod connected between the steel brush the driving shaft; a torque sensor mounted to the driving shaft for sensing the torque of the driving shaft and for emitting a sensing signal; a regulation unit having a second motor and a regulation screw having two ends connected with the second motor and the linking rod, respectively; and the control unit connected with the torque sensor and the second motor for controllably making the second motor regulate the regulation screw for prolongation according to the sensing signal. While the regulation screw is prolonged, the linking rod can be pushed to change the contact distance between the steel brush and the band saw for proper contact therebetween.
