This improvement can make full use of the blades in all directions of the disc hob , prolong the service life of the disc hob and save costs.

The bottom frame of the cutting knife is equipped with a knife slot that cooperates with the disc hob for cutting. The knife slot is located under the disc hob. The knife slot is composed of a nylon plate and an auxiliary knife plate; In addition to this scheme, there are many other schemes. For example, a groove matching the disc hob is left on the bottom frame of the cutter as a knife groove. The nylon plate has better shock resistance and wear resistance than ordinary The high-quality wooden board has a long service life, and the nylon board can effectively protect the blade of the disc hob.

A fixed assembly for fixing the movement of the zero-degree belt layer is installed on the installation frame, and the fixed assembly includes a cylinder installed on the installation frame and a pressure plate that the cylinder controls lifting.

The present invention also provides a method for using a zero-degree belt cutting device, including:

More than two zero-degree belt layers are fixedly arranged on the cutting device, and correspond to the disc hobs one by one; the cutter assembly presses the disc hob on the zero-degree belt layer; the driving mechanism controls the sliding of the cutter assembly. The zero-degree belt layer implements the cutting.
