[0002] The open mill is a key equipment in the field of rubber, plastic and other polymer material processing. It is a continuous, double-roller type plasticating and mixing equipment. It is mainly used for mixing, plasticizing, calendering and sheeting of polymer materials. During use, the materials are squeezed, sheared and mixed by two rollers rotating in opposite directions. The friction and adhesion between the material and the roller surface, as well as the bonding between the materials, pull the material into the gap between the two rollers. Under the strong shearing and squeezing action, the material becomes a sheet. Due to the temperature and speed difference between the two rollers, the material gradually becomes a sheet during the repeated shearing and squeezing process. Gradually soften to achieve the purpose of mixing and plasticizing; during the production process of the mixing mill, the operator needs to put his hands below two-thirds of the roller when feeding. The rubber materials of different sizes cannot enter the roller, and they need to be fed from above. When they are on the top, they are close to the roller and there is a safety hazard of putting hands in. Customized protective devices need to be specially customized according to the size of the mixing mill, which increases the production cost. Therefore, it is necessary to design a device to increase the safety protection of the mixing mill that can be adaptively adjusted according to the size of the mixing mill, while preventing operators from feeding materials at close range to improve the safety of the mixing mill production.
