[0002] Planetary mixer is a new type of high-efficiency mixing equipment without dead points. It has a unique and novel mixing form. There are two or three multi-layer paddle stirrers or one or two automatic scrapers in the mixing barrel. While the stirrer revolves around the axis of the mixing barrel, it also rotates at high speed around its own axis at different speeds, making the material in the mixing barrel do complex movements, subjecting it to strong shearing and kneading, thereby improving the mixing efficiency of the material.

[0003] According to Chinese patent application No.: 202221362219.2, a planetary mixer for mixing materials is disclosed, including a support foot, a main body is installed on the top of the support foot, a top cover is installed on the top of the main body, a sealing cover is installed on the top of the top cover, a motor is installed on the back of the sealing cover, and a group of connecting rods are installed on the inner side of the main body. By opening a guide groove, when the staff needs to open the sealing cover, the sealing cover can be pushed to the left by the handle, so that the sealing cover can drive the roller to roll along the guide groove with the rotating rod as the center through the bearing, the support column, the support plate and the rotating rod under the action of external force. At the same time, the roller will use its arc edge to push the support column to rotate with the bearing as the center through the rotating rod and the support plate under the action of external force and the guiding action of the guide groove, so that the roller can roll along the guide groove conveniently, and the sealing cover can move along the guide groove under the cooperation of the roller and the guide groove, so that the staff can open the sealing cover more conveniently and labor-savingly;
