Description

Spindle returning device of sizing machine Technical Field The utility model relates to the technical field of textile equipment, in particular to a yarn sizing machine spindle return device. Background In the sizing process, a back shaft (also called a 'moisture regain shaft') refers to an operation of re-unwinding part of the wound warp beam and returning the re-unwound warp beam to a sizing tank for secondary treatment due to process requirements or quality control after sizing and drying of warp yarns, and the step is generally used for adjusting the slurry permeability and moisture regain of yarns or making up the defect of primary sizing. The warp beam unwinding device of the sizing machine after improvement disclosed in CN201721002818.2 can not realize effective control of the yarn back shaft tension, and the yarn breakage is easily caused by the excessive tension, the tension is too small, and the yarn loosens and is twisted, so that the yarn back shaft device of the sizing machine is developed. Disclosure of utility model The utility model aims to provide a sizing machine back shaft device which solves the technical problems in the background technology. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model discloses a sizing machine back shaft device which comprises a radial shaft frame and a guide frame, wherein the radial shaft frame and the guide frame are arranged side by side, two groups of radial shaft supporting seats are symmetrically and fixedly arranged on the radial shaft frame, a lower radial shaft and an upper radial shaft are sequentially arranged between the lower parts and the upper parts of the two opposite radial shaft supporting seats, two vertical first mounting plates are symmetrically and fixedly arranged at one end of the guide frame, first winding and unwinding guide rollers are respectively arranged at two sides of the two first mounting plates in a rotating manner, the distance between the two first winding and unwinding guide rollers can be adjusted, two vertical second mounting plates are symmetrically and fixedly arranged at the other end of the guide frame, and a second winding and unwinding guide roller is rotatably arranged between the upper parts of the two second mounting plates.
