[0002] A circular die-cutter is a type of automated cutting equipment widely used in various industries, particularly in paper packaging, plastic products, and electronic components. It uses a rotating circular knife to cut materials into the desired shape and size. The main components of a circular die-cutter include the frame, drive system, cutting system, and control system. The circular die-cutter uses a rolling cutter to continuously rotate and cut the product. It is one of the most efficient die-cutting machines and is a common sight in everyday life.

The die-cutting pad roller, the die-cutting bottom roller, and the magnetic roller are rotatably installed on the side plate from bottom to top in sequence. The driving motor is used to drive the die-cutting pad roller, the die-cutting bottom roller, and the magnetic roller to rotate. The die-cutting pressure mechanism is used to adjust the magnetic roller to move up and down. A die-cutting knife is provided on the magnetic roller. When in use, the material passes through the gap between the die-cutting bottom roller and the magnetic roller. The die-cutting pressure mechanism located above the magnetic roller applies downward pressure to the magnetic roller to adjust the pressure of the die-cutting knife relative to the material. During the operation of the equipment, the die-cutting pad roller drives the die-cutting bottom roller and the magnetic roller to rotate. The die-cutting knife on the magnetic roller corresponds to the position on the material that needs to be die-cut, so that the die-cutting knife can accurately complete the die-cutting process of the material.

At this time, it will be convenient to adjust the distance between the lower die roller 6 and the upper die roller 3.

[0034] After the lower die roller 6 has been used for a long time, in order to facilitate the replacement and fixation of the lower die roller 6, the rotating columns 51 on both sides of the inner wall of the mounting frame 1 are first rotated to the appropriate position, so that the inlay groove 53 opened on the surface of the rotating column 51 faces directly upwards, and then the replaced lower die roller 6 is plugged into the inlay groove 53 with the help of the inlay blocks 54 at both ends, and the fixed column 56 is plugged into the through hole 55, and the fixed column 56 will be plugged into the inlay block 54, and then the fixing ring 52 on the surface of the rotating column 51 is threadedly rotated. At this time, the entire lower die roller 6 can be conveniently installed and replaced.
