Improved auxiliary cloth rewinder matching an advertisement inkjet printer and enabling a reel to retractable in a radial manner

An improved auxiliary cloth rewinder matching an advertisement inkjet printer and enabling a reel to retractable in a radial manner is mainly used for coordination with an inkjet printer to automatically roll up an inkjet frame. The improved auxiliary cloth rewinder is characterized by being equipped with a reel retractable in a radial manner, wherein the reel is formed by two semi-cylinders, the two semi-cylinders and a central rotating shaft are in a cam-like cooperation relationship, the two semi-cylinders can be pushed open or be loosened under the rotation of the central rotating shaft, and thus the reel is retractable in a radial manner. When the improved auxiliary cloth rewinder is in use, the reel retractable in a radial manner is mounted on a bearer, the inkjet frame winds around a hollow roller and passes through a gap between two parallel hollow rollers, two simple spring clips are utilized to clamp cloth heads on two ends of the inkjet frame, a speed variable motor is started to drive the reel to rotate, and the inkjet frame starts being rolled automatically. After cloth rolling is finished, the simple spring clips are loosened, a handle is pulled up to rotate in a reverse direction, and thus the reel can be easily retractable in a radial manner and is easy to pull out. In this way, the inkjet frame can be rolled automatically without consumption of a lot of paper tube sleeves.
