Saw band chip sweeping device and band sawing machine using same

Abstract

The invention relates to a saw band chip sweeping device and a band sawing machine using the same. The saw band chip sweeping device comprises a mounting fixed seat and a mounting rotating seat, and amotor connecting shaft, a right bevel gear pair, a connecting shaft block, a transmission shaft and a left bevel gear pair are separately arranged in the mounting fixed seat and the mounting rotatingseat; the right bevel gear pair drives a right chip sweeping wheel to rotate clockwise through a right chip sweeping wheel shaft, the left bevel gear pair drives a left chip sweeping wheel to rotateanticlockwise through a left chip sweeping wheel shaft, and the motor connecting shaft drives the transmission shaft to rotate together through the connecting shaft block, so that the right bevel gearpair and the left bevel gear pair are driven to rotate simultaneously, and finally the right chip sweeping wheel and the left chip sweeping wheel are driven to rotate simultaneously; and a spring seat is arranged on the mounting fixed seat, a rotating shaft seat is arranged on the mounting rotating seat, a compression spring and a spring rod are arranged in the spring seat, and one end of the spring rod is rotationally connected with the rotating shaft seat through a rotating shaft. The saw band chip sweeping device has the characteristics that chips are swept thoroughly, saw bands are convenient to replace, and the distance between the chip sweeping wheels is convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of band sawing machines, in particular to a band sawing device and a band sawing machine using the device. Background technique [0002] As a commonly used metal processing machine tool, band sawing machine is widely used in industry, agriculture, construction and other fields. During the sawing process of the band sawing machine, a large amount of iron filings will be accumulated in the chip pocket of the saw band. Generally, the iron filings in the saw band chip pocket will separate from the saw blade by itself, but there will still be some iron filings due to various reasons. Adhesion in the chip slot of the saw band, and because the teeth on the saw band are staggered from left to right, the iron filings in the chip slot are also scattered, which affects the normal operation of the saw band. These iron filings will interfere with the normal sawing process, and these iron filings will greatly affect the ...

AI Technical Summary

Problems solved by technology

Although this structural method solves the problem of incomplete chip removal, it makes it inconvenient to replace the saw band, and it is also inconvenient to replace the chip removal wheel at the same time.

And it is impossible to adjust the angle between the chip sweeping mechanism and the saw blade, which is very inconvenient

The existing two-wheel chip sweeping method of the saw band has more or less shortcomings such as incomplete chip removal, inconvenient replacement of the band saw, and complicated adjustment of the chip sweep wheel.
