Battery foil rewinding machine lowering breakage risk

Abstract

The invention relates to the technical field of rewinding machines and discloses a battery foil rewinding machine lowering breakage risk. The battery foil rewinding machine lowering the breakage riskcomprises a base. The outer surface of the upper end of the base is provided with an installation plate. The outer surface of the front end of the installation plate is provided with an unwinding roller. The surface of the back end of the unwinding roller is provided with a first limiting disk. The surface of the back end of the installation plate is provided with a brake structure corresponding to the tail end of the unwinding roller. The side end of the unwinding roller is provided with a winding roller. The surface of the back end of the winding roller is provided with a second limiting disk. The outer surface of the front end of the lower portion of the installation plate is provided with a first tension roller. The side end of the first tension roller is provided with a second tensionroller. A tension sensor is arranged between the first tension roller and the second tension roller. The battery foil rewinding machine lowering the breakage risk is provided with a winding roller enabling the battery foil to be conveniently installed, the tension of the battery foil in the rewinding process can be monitored in real time, the tension of the battery foil in the rewinding process is adjusted beneficially, and a brake function can be provided for the unwinding roller.

Description

technical field [0001] The invention relates to the field of rewinders, in particular to a battery foil rewinder that reduces the risk of tape breakage. Background technique [0002] Battery aluminum foil (Battery aluminum foil) is used as a current collector for lithium-ion batteries. Generally, the lithium-ion battery industry uses rolled aluminum foil as a positive electrode current collector; while battery foil needs to be rewound and cut during the production process, but now Some rewinding machines do have some problems during use. First, it is inconvenient to install the reel of the battery foil on the surface of the unwinding roller and the rewinding roller. The change in the weight of the battery foil will lead to unstable tension, which will easily cause the battery foil to break. Finally, the unwinding roller does not have a brake function during the unwinding process, which may easily cause insufficient tension of the battery foil during the unwinding process. Th...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a battery foil rewinding machine that reduces the risk of tape breakage. It is equipped with a winding drum for easy installation of the battery foil, and can monitor the tension of the battery foil during the rewinding process in real time, which is conducive to adjustment The tension of the battery foil during the rewinding process can provide the advantage of braking the unwinding roller, which solves the problem that the traditional rewinder battery foil reel is not easy to install and cannot monitor the tension of the battery foil during the rewinding process in real time. Tension, it is not convenient to adjust the tension of the battery foil during the rewinding process, and it is impossible to provide a braking function for the unwinding roller
