The fabric for outdoor appliances such as umbrellas and tents or for industrial use is generally warp-knitted polyester fabric, and the fabric is generally subjected to waterproof, flame-retardant and other processes before the manufacture of products. The processes of the processes are simply scutching, flattening, gluing, drying and rolling. Although there are multiple processes, the entire production line is typically an integrated conveyor line. Therefore, the tension of the whole conveying line needs to be controlled to be stable, the gluing and drying process time is stable, and the product quality is guaranteed. The existing cloth uncoiler generally comprises a roller for mounting a cloth coil, which is called an uncoiling roller, and a plurality of driving rollers and driven rollers. The unwinding roller and the following driven roller are generally far away from each other, and if the cloth has folded edges or creases, the cloth can be flattened after being greatly unfolded. Due to the space taken up by the apparatus, the driven roller immediately adjacent to the unwinding roller is placed on top. Even so, current decoiler unit is owing to adopt the mode control tension of control drive roll rotational speed, therefore needs more drive roll and driven voller, and the installation space that corresponds is bigger, and spare part is intensive moreover and is unfavorable for overhauing and maintaining. On the other hand, the manner of adjusting the tension by adjusting the rotation speed is relatively indirect, and the response speed is slow. Especially, the large-scale unwinding from the unwinding roller to the first driven roller is easy to generate tension fluctuation, and the tension of the cloth at the subsequent section can be influenced.

Therefore, the existing cloth uncoiling device has the problems of relatively large occupied space, inconvenient maintenance and overhaul and relatively large tension fluctuation.
