Anti-strip-running wood cutting equipment using inertia and static to remove sawdust

Abstract

The invention discloses anti-strip-running wood cutting equipment using inertia and static to remove sawdust. The wood cutting equipment structurally comprises an upper saw wheel box, a tightening handwheel, a movable backer plate, a saw blade, a workbench, a suction sawdust removal pipe, a foot brake plate, an anti-strip-running device and a machine base. According to the wood cutting equipment,a driving shaft drives a rotating wheel to rotate, and a brush head with positive electricity is driven to rotate through a conductive ring, so that the sawdust adhering to the inner surface of a sawblade is centrifugally thrown out in the tangential direction of the brush head under the scraping inertia force of the brush head, and the situation that the damp sawdust adheres to the inner side surface of the saw blade, and then the sawdust is accumulated on the contact surface between the saw blade and the rotating wheel, so that strip running is caused to the saw blade, and the saw is proneto being stretched and broken is prevented; and meanwhile, an upper rotating plate and a lower rotating plate are staggered to be with negative electricity under the action of a generator and a conductive rod so as to attract the sawdust which is blown by an air injection gun and is positively charged, then the sawdust is collected, then, a low-temperature environment is formed by utilizing a cooling cavity and a circulating cavity so as to cool the saw blade penetrating thereinto, then the saw blade is prevented from being stretched and broken due to high temperature, meanwhile, electric charges are conducted through a static removing pad, the static on the saw blade is removed, and then a lower saw wheel is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of wood processing, more precisely, it is a wood cutting device using inertial electrostatic chip removal and anti-running strips. Background technique [0002] With the improvement of mechanical automation and living standards, the use of boards is increasing. The boards are obtained by cutting logs with a band saw machine and then processing them. At present, the wood chips generated during cutting are concentrated and removed by fan suction. The existing traditional Technical considerations are not comprehensive and have the following disadvantages: [0003] The log pine wood is easy to be affected by moisture. After a long period of storage, its outer circle absorbs water and moisture, and the pine wood itself contains relatively rich oil. The sawdust produced by cutting is wet and oily and has strong adhesion. The saw blade cannot be completely cleaned only by the suction of the fan. The sawdust is put on, so th...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a wood cutting device using inertial electrostatic chip removal and anti-running strips, so as to solve the problem that the log pine in the prior art is easy to be affected by moisture. Pine wood itself is rich in oil, and the wood chips produced by cutting are moist and oily and have strong adhesion. Only the suction of the fan cannot completely clean the wood chips on the saw blade, so that the wet wood chips continue to accumulate on the inside of the saw blade and the lower saw wheel. The gap surface in contact not only increases the gap between the saw blade and the saw wheel to cause strip running, but also makes the saw blade continuously tightened, resulting in the defect that the saw blade is prone to vibration and breakage during sawing
