Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, and in particular to a material unloading and turning device for a rewinding machine. Background Art

[0002] The rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls produced by the paper machine in sequence. After the paper rolls are rewound, they are made into finished paper and shipped out of the factory. After the paper rolls are rewound by the rewinder, the paper rolls need to be unloaded so that they are in a vertical state. The vertical paper rolls are not easy to roll and are convenient for subsequent handling and storage.

[0003] Most of the existing rewinding machine unloading methods are done manually. After the paper roll is rewound, multiple operators are required to take the paper roll off the rewinding roller of the rewinder and store it by turning it over. If there are operating errors or inconsistent actions during unloading and turning, this may cause the paper roll to break and cause material waste. Utility Model Content
