MECHANISM FOR CHANGING DIRECTION OF MATERIAL STRIP, DRYING APPARATUS, AND ELECTRODE PLATE MANUFACTURING DEVICE

WIPO Patent Application WO/2023/159937

A1

A mechanism (100) for changing the direction of a material strip, used for changing a strip feeding direction of a material strip, and comprising a negative pressure unit (10) and an air outlet unit (20). The negative pressure unit and the air outlet unit are arranged oppositely and a gap allowing the material strip to pass through is formed between the negative pressure unit and the air outlet unit; the negative pressure unit is configured to provide attractive force for the material strip, and the air outlet unit is configured to provide repulsive force for the material strip, so that the material strip is not in contact with the negative pressure unit and the air outlet unit. The mechanism for changing the direction of a material strip can improve battery production efficiency. The mechanism further comprises a drying apparatus (200) and an electrode plate manufacturing device which are provided with the mechanism for changing the direction of a material strip.
