Abstract
The invention discloses a leather material uncoiling driving mechanism. The leather material uncoiling driving mechanism comprises a motor, a driving roller and a material pressing roller. The motor, the driving roller and the material pressing roller are mounted on a rack. The driving roller and the material pressing roller are parallel with each other. A horizontal material piece gap is formed between the driving roller and the material pressing roller. The driving roller is connected with the motor. The material pressing roller is mounted on the rack through a tensioning type material pressing mechanism. The tensioning type material pressing mechanism is used for enabling the uncoiling driving mechanism to have two working states, namely the working state and the relaxed state. When the uncoiling driving mechanism is in the working state, the material piece gap between the driving roller and the material pressing roller is matched with thickness of a leather material. When the uncoiling driving mechanism is in the relaxed state, the material piece gap between the driving roller and the material pressing roller is as wide as not less than one centimeter.
