Sawing machine provided with high-precision saw blade positioning device

Abstract

The invention discloses a sawing machine provided with a high-precision saw blade positioning device. The sawing machine comprises a saw blade, a saw blade transmission device and the saw blade positioning device, the saw blade positioning device abuts on the saw blade to enable a saw blade cutting area to be vertical, and comprises an upper positioning wheel and a lower positioning wheel, and the upper positioning wheel and the lower positioning wheel with wheel faces abutting on the saw blade are arranged at the upper end and the lower end of a support frame respectively. The sawing machine is simple in structure, the positioning device is high in precision, rolling friction force of the saw blade and the upper and lower positioning wheels is small, the upper and lower positioning wheels are free of wear and shaking after long-time use, the saw blade in the cutting area is in an optimal vertical tensioning state constantly, left-right eccentricity can be avoided during operation of the saw blade, sawn wood lines hardly have any deviation, and the sawing machine is more obvious in advantages particularly when used for making veneers, and is cost-saving and high in production efficiency.

Description

technical field [0001] The invention relates to the field of wood processing equipment, in particular to a sawing machine provided with a high-precision saw blade positioning device. Background technique [0002] At present, the positioning of the saw blade of the wood sawing machine is mainly carried out by positioning the positioning block against the upper and lower ends of the saw blade cutting area. When the sawing machine is running, the saw blade constantly rubs against the positioning block, because the sliding friction between the two is large. With the wear and tear of the positioning blocks, the positioning gap continues to increase, and the saw blade will be eccentric when running, resulting in a large deviation in the sawing wood line, resulting in unnecessary waste, so new positioning blocks must be replaced frequently. If the waste is greater when making thin boards, for example, if you want to make a finished wooden board with a thickness of 4mm, you need t...

AI Technical Summary

Problems solved by technology

[0002] At present, the positioning of the saw blade of the wood sawing machine is mainly performed by the positioning block against the upper and lower ends of the cutting area of ​​the saw blade. When the sawing machine is running, the saw blade is constantly rubbing Positioning blocks, because the sliding friction between the two is large, with the wear of the positioning blocks, the positioning gap will continue to increase. Necessary waste, so it is necessary to replace new positioning blocks from time to time

If the waste is greater when making thin boards, for example, if you want to make a finished wooden board with a thickness of 4mm, you need to make a 7mm rough blank, and leave an extra 3mm of material as a margin, which accounts for 42% of the finished product, especially expensive wood. , it's a pity to waste so much
