TECHNICAL FIELD

[0001] The utility model belongs to the technical field of die cutting equipment, and particularly relates to a knife mounting seat in a digital die cutting equipment. BACKGROUND

[0002] In the existing digital die cutting equipment, the knife is mounted in the seat and passively rotates with the seat to change the cutting direction. The conventional seat structure is usually provided with a bearing at the front part, the knife rotates in the bearing, and the tail part of the knife adopts the mode of magnet combined with the bearing to prevent the knife from falling. However, this structure has obvious defects. Due to the magnet adsorption, the bearing is magnetized, the magnetic field between the inner ring, the outer ring and the steel ball interacts, which seriously affects the flexibility of the knife rotation, and the jamming phenomenon frequently occurs. At the same time, due to the structural limitation, the bearing specification of the tail part of the knife is small, and the inner diameter is generally not more than 2mm. In the long-term use, the impact load caused by the frequent falling of the knife easily causes the damage of the bearing, further aggravates the knife rotation jamming problem, and leads to poor cutting effect, such as the falling of the knife tip causing poor cutting, which not only reduces the work efficiency, but also causes material waste. In addition, when adjusting the length of the knife tip exposed, the tail part of the seat needs to be loosened and the nut is tightened, which is complicated to operate and the seat must be taken off, which is extremely inconvenient. Moreover, the head part of the seat is made of metal aluminum material, and the glue is easily adhered to the head part of the seat when processing materials such as film-coated adhesive, and even blocks the rotation of the knife after accumulation, which seriously affects the cutting operation.
