Description

Technical Field

[0001] The utility model relates to the field of lithium battery winding machines, in particular to a fixing structure for a sleeve supply roller for lithium battery film covering. Background Art

[0002] The sleeve supply roller in the lithium battery film covering equipment is to ensure that the sleeve (usually an insulating film) can be smoothly and accurately conveyed to the film covering position. This kind of roller usually consists of a roller, a roller shaft, a bearing and a connecting rod. One end of the connecting rod is fixed to the workbench, and the other end is fixed to the roller shaft. The roller shaft is located inside the roller to support the roller. Under the action of the bearing, the roller can rotate around the shaft. The rotation of the roller drives the sleeve material to move, and in cooperation with the film covering equipment, the ear of the lithium battery is replaced. During this process, the sleeve supply roller of the lithium battery film covering equipment may experience pulsed shear force, which may cause the roller shaft to break during long-term operation, resulting in equipment failure and affecting production. How to reduce the pulsed shear force received by the roller shaft during actual operation has become a difficult problem. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a fixing structure for a sleeve supply roller for lithium battery film covering, which can reduce the pulsed shear force received by the roller shaft during actual operation.
