Problems solved by technology

In the previous sawing part bearing configuration, the bearings at both ends of the bearing housing adopt deep groove ball bearings. Due to the inherent axial clearance of about 0.18mm ~ 0.30mm inside the deep groove ball bearings, the high-speed rotating saw blade Axial movement occurs when the board is sawed, resulting in corrugated lines, chipping and burnt phenomenon on the edge of the board after sawing, which seriously affects the appearance quality and product qualification rate of the finished board

Abstract

The match corner joint contact ball bearing for board cutting applies small axle direction lash 0.022-0.03mm match corner contact ball bearing as the bearing of the fastening end of the spanner cutting section to improve the appearance of the final product. It improves the sawing quality, with improved cosmetics and pass rate of the product.

Description

technical field [0001] The invention relates to a sawing machine technology, in particular to a sawing part bearing arrangement technology for cutting wood-based panels and secondary laminated panels. Background technique [0002] The sawing machine is one of the important auxiliary machines on the production line of wood-based panels and secondary veneers. Its function is to cut the pressed or pasted panels according to certain specifications. The sawing part is the core of the sawing machine, and its structural design directly affects the sawing quality and qualification rate of the finished board. In the previous sawing part bearing configuration, the bearings at both ends of the bearing housing adopt deep groove ball bearings. Due to the inherent axial clearance of about 0.18mm ~ 0.30mm inside the deep groove ball bearings, the high-speed rotating saw blade Axial movement occurs when the board is sawed, resulting in corrugated lines, chipping and burnt phenomenon on the...
