Two-sided trimmer for logs

Abstract

The invention relates to the field of log processing equipment and particularly relates to a two-sided trimmer for logs. The two-sided trimmer comprises a machine frame, wherein a cutting device is arranged on the machine frame and comprises a cutting knife shaft which is mounted on the machine frame through a bearing seat, the middle part of the cutting knife shaft is connected to a first motor through a first driving wheel and a first transmission belt, and cutting knives matched with log plates are arranged at the two ends of the cutting knife shaft. The two-sided trimmer for the logs, provided by the invention, has the aims that the cutting device is designed to have two parallel cutting knives, and meanwhile, the gap between the cutting knives is controlled to be consistent with a log required size, so that both sides of each log plate can be trimmed in one time, the cutting efficiency is greatly increased, the cutting time is saved, and the dimensional error of one-time cutting is reduced compared with that of two-time cutting.

Description

technical field [0001] The invention relates to the field of log processing equipment, in particular to a log double-side trimming machine. Background technique [0002] As paper is used more and more widely, the production of logs is also increasing. Most of the logs used in papermaking must first be made into log boards, and then the log boards are trimmed according to the specific size requirements. [0003] Most of the existing log trimming uses a cutting device. It is necessary to first draw a cutting line on the original wood board, and then use the cutting device to trim the original wood board, and then cut out the required size of the original wood board. Trimming in this way The efficiency is low, and the length or width needs to be cut twice, which greatly consumes the cutting time, and the two cuts will produce a little error, which will lead to a large size error of the cut original wood board.
