Band sawing machine for cutting long-strip-shaped timber

Abstract

The invention discloses a band-sawing machine for cutting long-strip-shaped timber, which comprises a machine shell, a driving mechanism arranged on one side of the machine shell and a workbench arranged on one side of the machine shell, the driving mechanism comprises a motor, one end of an output shaft of the motor is connected with a driving wheel, the upper part of the machine shell is provided with a driven wheel, and the driving wheel is connected with the driven wheel through a saw band; the saw belt penetrates through the workbench and is arranged in the middle of the workbench. A backer is arranged on one side of the upper portion of the workbench, sleeves are fixedly installed on the two sides of the lower portion of the workbench, telescopic rods are slidably installed in the sleeves, one ends of the two telescopic rods are connected through a supporting plate, and an end plate is arranged at one end of the supporting plate. The telescopic rod is arranged on the lower portion of the workbench, the supporting plate for supporting the end of wood is arranged at the end of the telescopic rod, inaccurate wood cutting caused by the head warping phenomenon in the wood cutting process is avoided, meanwhile, the safety of long-strip-shaped wood cutting is guaranteed, cutting and discharging of long-strip-shaped wood can be completed by one person, and the working efficiency is improved. And the human resource cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of band sawing machines, in particular to a band sawing machine used for cutting long strips of wood. Background technique [0002] A band saw is a sawing machine that uses an endless band saw blade as a saw tool, and is wound around two saw wheels to make a one-way continuous linear motion to saw wood. When the band saw machine cuts long wood workpieces, Due to the limited support size of the workbench, the cut wood tends to tilt downward after moving to the other side of the workbench, causing the uncut wood to be warped. In addition, after the wood cutting trajectory is changed, it is unavoidable to generate a lateral thrust on the saw belt, which is easy to cause the saw belt to break, which seriously affects the safety of long-size wood cutting operations. At present, two methods are often used to solve this problem. The two people are arranged on both sides of the band saw machine. One worker pushes t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a band saw machine for cutting long strips of wood, so as to solve the problem of warping of the existing long-sized wood, which causes the change of the moving track of the wood and affects the cutting of the wood. The problem of precision, and at the same time avoid the problem of saw band breakage due to the lateral thrust of wood on the saw band
