In order to improve the crushing performance of the crushing device for medical protective cloth-ing mixture,the crushing device needs to be optimized.Using the method of modular design and crushing process analysis,the moving knife installation angle and tool post installation layout of medical protective clothing crushing device were improved.ADAMS was used to simulate the crushing device before and after optimization.The results show that the shearing force of the crushing device on the medical protective clothing is increased by 34％after the installation angle of the crushing knife is increased from the horizon-tal installation to an angle of 60.8° with the horizontal direction.The moving tool holder is arranged at an interval of 15°.The stress on the tool holder during operation decreases from 3960N to 660N.When the op-timized single roller grinder tool holder layout cuts the medical protective clothing mixture,the angular velocity fluctuation range decreases from 625°/s-820°/s to 700°/s-800°/s,the angular acceleration does not fluctuate significantly,and the vibration is significantly reduced.It provides a design reference for the per-formance improvement of medical protective clothing crushing device.
