[0002] In the process of battery slurry production, the slurry needs to be mixed. When mixing the slurry, the required high viscosity and high kneading properties are a major test for the mixer and the transmission chain. In order to meet the production needs, the existing mixers have added chain tensioning devices to the mixers. After the existing sprockets have worked for a period of time, the chain will become loose. If the sprocket tension is not adjusted, the chain may be separated from the rotating wheel. If it is in a high-speed running state, the chain may be thrown out directly, posing a threat to the surrounding personnel and equipment. Therefore, a tensioning device is needed to tension the chain to prevent accidental injuries. However, most of the existing tensioning devices have a complex structure, and the use of equipment such as hydraulic cylinders is inconvenient to operate.
