The utility model provides a normal-temperature overflow dyeing machine, which comprises a cloth guide roller device, a motor, a belt A, a belt B and a cloth swinging device, wherein the cloth guide roller device is connected with the motor through the belt A; and the cloth swinging device is connected with the motor through the belt B. The utility model has the advantages that: through simple structural improvements, the cloth guide roller device 1 and the cloth swinging device 5 run synchronously, so that grey cloth is circulated flatly and orderly, the cropping flatness is enhanced, the running stability is enhanced, permanent corrugations caused by twisting of the grey cloth into a rope under the damaging action is avoided, machine winding caused by unsmooth running of the grey cloth is prevented, and caused quality problems such as section difference, section disorder, pattern and the like are solved. When the speed of the cloth guide roller device is increased, the speed of the cloth swinging device is increased, so that the problems of weft obliqueness, arc obliqueness and the like caused by non-uniform impact of high-speed liquid flow on the grey cloth can be solved.
