Synthetic leather unwinding device

The utility model belongs to the field of material processing, and particularly relates to a synthetic leather unwinding device which comprises a winding machine. A sliding groove is formed in the top of the winding machine, two sliding blocks are slidably connected to the middle of the sliding groove, supporting plates are fixedly connected to the tops of the sliding blocks, the two supporting plates are oppositely arranged, two supporting shafts are fixedly connected to the side walls of the supporting plates, and rollers are rotatably connected to the middles of the supporting shafts. Synthetic leather of different sizes can be placed between the two rollers to be attached, the synthetic leather is placed between the two rollers, the two rollers are attached to the synthetic leather, so that the synthetic leather can be evenly stressed during unwinding, the situation that the synthetic leather is wrinkled or deformed during unwinding is reduced, and the production efficiency of the synthetic leather is imp
