Description

Technical Field

[0001] The utility model relates to the technical field of battery processing devices, in particular to an installation structure of an automatic film-threading sprocket. Background Art

[0002] Traditional film threading technology uses manual threading, which is inefficient, has a high error rate, and is labor-intensive for operators. Automatic threading is generally used now. Automatic threading mainly uses a film threading sprocket to drive the chain to realize the film threading driven by the film threading chain. However, the film threading sprocket is installed coaxially with the roller, that is, the film threading sprocket is mounted on the roller shaft of the roller. This installation method has substantial shortcomings: first, the film threading sprocket is heavy and is installed on one side of the roller shaft, which easily makes the roller unbalanced and also requires a high strength of the roller shaft section where the sprocket is installed; second, the film threading chain is only used when starting and stopping, and rotates with the roller for a long time, which imposes additional load on the bearings of the roller shaft section, causing excessive unbalanced load wear of the roller bearings, resulting in a short bearing life. When replacing damaged bearings, the roller needs to be disassembled, which is time-consuming and labor-intensive, inconvenient to repair, and costly.

[0003] Therefore, it is necessary to provide an installation structure for an automatic film-threading sprocket to solve the above problems. Utility Model Content
