Description

Saw band anti-reverse device

The invention relates to a driving wheel structure, in particular to a saw band anti-reverse device for preventing the driving wheel from being reversed.

In conventional technology, the band saw machine connects the driving wheel and the driving wheel at the bow, and the saw belt is wound around the radial outer edge of the driving wheel and the driving wheel, and the driving belt is driven to rotate to drive the saw band for sawing. Generally speaking, when operating a band saw machine, the sawing speed of the saw band needs to be adjusted according to the material characteristics of the workpiece. For example, a softer material can be cut at a faster speed, but a harder material needs to be slower. The sawing speed is not only to avoid breaking the saw band, but also to make the saw band have better sawing efficiency.

For the above-mentioned band saw machine, in order to achieve the purpose of strong cutting, the flywheel effect will be generated during the rotation of the driving wheel, causing the driving wheel to reverse, or in the cutting of high-speed feed rate, a reactive force will be generated at the tool tip. This will also cause the driving wheel to have a reverse effect. Therefore, how to provide a "saw band anti-reverse device" to solve the above problems is an urgent problem in the related technical field.

The invention provides a saw band anti-reverse device. By installing a non-reverse component on a transmission shaft, the anti-reverse component is used to restrict the driving wheel from rotating in a single direction so that the driving wheel does not reverse, so as to achieve the function of strong cutting.

In one embodiment, the present invention provides a saw band anti-reverse device, which includes a driving wheel, a transmission component, a driving component, and a non-return component. The transmission component is linked with a transmission shaft. The drive assembly is connected to the drive shaft. The transmission shaft is penetrated by the anti-reverse component. The driving component drives the transmission shaft to drive the driving wheel to rotate. The anti-reverse component is used to restrict the driving wheel from rotating in a single direction.
