[0002] The cutting machine is the most crucial and main equipment in the cigarette making workshop. The cutting machine is a general term for the leaf cutting machine and the stem cutting machine, and is one of the key equipment on the tobacco cigarette making production line. The basic function of the cutting machine is to cut the processed tobacco leaves or tobacco stems into leaf silk and stem silk with widths meeting the requirements of the tobacco cigarette making process specifications. During the production process, the blades and grinding wheels are constantly consumed, and the operators of the cutting machine need to regularly replace the blades and grinding wheels. The grinding wheel disc is the main component of the grinding wheel assembly in the cutting machine's knife grinding system, used to install and fix the grinding wheel on the rotor of the grinding wheel motor, so that it can grind the blades under the drive of the motor. It is also a component that the operator of the cutting machine's knife roller grinding system needs to often operate on.

[0003] Currently, there are certain potential hazards and problems when replacing the grinding wheel. When installing the grinding wheel, it is necessary to hold the grinding wheel with both hands, align the grinding wheel positioning pin shaft at the bottom of the grinding wheel from the bottom of the grinding wheel assembly, hold the grinding wheel with one hand, and use the other hand to hold the grinding wheel fixing screw (3 pieces of 8mm hexagon socket head cap screws) for installation operation, resulting in the installation process being unable to be completed by a single person, with low installation efficiency and high labor costs; moreover, since the staff needs to hold the grinding wheel disc by hand for installation, it is impossible for the staff to maintain a certain safety distance from the grinding wheel disc, and the falling off of the grinding wheel disc is likely to cause a bruise accident.
