At present, the brassica juncea peeling machine has some malpractice, such as low production efficiency, higher labor intensity and high accident rate. According to the situation, a kind of new peeling machine was designed. The automatic load centring mechanism was used to center and preclamp the material. The intermittent transmission mechanism was used for feeding on material. The stuck in and rotation mechanism was used to stuck tightly and provide power for peeling. In the end, the cutting mechanism finished the work and then the processed brassica juncea was taken out. The next circulation would begin. This design provides a solution for the processing of similarity material.
