[0002] A die-cutting machine is a mechanical device used to cut or punch a flat material according to the shape designed by a mold. It is mainly applied in the processing of various materials, and the material is processed by pressure and the mold for cutting, punching, embossing, etc. to produce a shape and size that meet the requirements. When the die-cutting machine cuts and punches, the cutting tool needs to be fixed by a corresponding knife seat. In the existing knife seat, during use, the tool is usually fixed by thread clamping or other simple methods, making the tool prone to looseness or deviation, affecting the processing accuracy and safety. Therefore, we propose a frame-type knife seat structure for a die-cutting machine to solve the problems mentioned above. Content of the Utility Model
