[0002] The knife belt is a cutting component used to cut some objects. It is mainly used in CNC sponge cutting machines. When the machine drives the knife belt, the knife belt cuts objects such as sponges through the cutting edge on its side. During use, in order to ensure the sharpness of the knife belt, its cutting edge needs to be polished frequently. At this time, a knife belt continuous polishing device is required. The knife belt continuous polishing device mainly drives the knife belt through two sets of roller structures. During the transmission of the knife belt, the polishing component continuously polishes its cutting edge to complete the polishing operation.

In view of this, we propose a continuous knife belt grinding device. Utility Model Content
