Abstract

The invention discloses a pre-shrinking machine capable of rotationally switching heating rollers. A tensioning roller is arranged on the lower portion in a machine box in a lifting manner. A pair ofauxiliary rollers is positioned between a pair of conveying driving rollers. A rubber blanket is arranged on the pair of auxiliary rollers, the pair of conveying driving rollers and the tensioning roller. A switching device comprises a pair of front and back supporting plates which are symmetrically arranged front and back. The pair of front and back supporting plates is arranged at the upper partin the machine box in a lifting manner. The pair of front and back supporting plates is positioned on the front and back sides of the rubber blanket. A hollow central connecting column in a regular polygon column shape is rotationally arranged between the pair of front and back supporting plates. Rotary supporting plates are formed at the front end and the back end of each end face of the centralconnecting column correspondingly. A heating roller is rotationally arranged between each pair of rotary supporting plates on the same side. The diameters of the heating rollers are different. The heating roller at the lowermost end downwards presses the part, between the pair of auxiliary rollers, of the rubber blanket.

Description

Technical field[0001]The invention relates to the technical field of preshrinking machines, in particular to a preshrinking machine with a rotary switching heating roller.Background technique[0002]The pre-shrinking machine uses mechanical and physical methods to improve the weaving and shrinkage of the yarns in the fabric, increasing the weft density and radial weaving of the fabric, thereby stabilizing the shrinkage rate of the fabric, improving the quality and dimensional stability of the fabric, and improving the physical properties of the fabric Or to protect the surface quality of the fabric, the existing pre-shrinking machine directly presses the heating roller between the cloth feeding roller and the cloth discharging roller, and the positions of the cloth feeding roller, cloth discharging roller and heating roller are unchanged, so that the cloth heating time No change, but different fabrics have different shrinkage rates, which leads to different pre-shrinking effects of di...
