Description

Scrap removing device for feed roll of square wood multi-blade saw

Technical Field

The utility model relates to a timber processing field especially relates to a feed roll of square timber multi-blade saw removes bits device.

Background

The square wood multi-blade saw has the advantages of smooth feeding, fine processing, no saw blade burning, high work efficiency, low material consumption, safety, environmental protection and the like. Square lumber multi-blade saws are widely used in various lumber processing plants. At present the conveyer of square timber multiple blade saw generally is many feed rolls of arranging along direction of transfer, and in order to increase the frictional force between feed roll and the square timber, feed roll surface interval is equipped with arch and recess. In-process that saw cuts is carried out at the square timber, the saw-dust that the saw bit produced can splash the back and drop, the saw-dust that drops on the feed roll surface can remain on the feed roll, fill up the recess on feed roll surface, the frictional force with the square timber that leads to the feed roll reduces, and saw cut the in-process, the saw bit can produce the effort backward to the square timber, this effort is overcome by the frictional force between square timber and the feed roll, in case the backward effort of saw bit to the square timber can't be overcome to frictional force, will lead to the square timber to skid on the feed roll, the process time has been prolonged, and the in-process that traditional square timber saw cut can splash, be full of workman's operational environment, harm workman's health.
