Abstract
The utility model relates to the technical field of chemical fiber stretching devices, and discloses a chemical fiber stretching device which comprises an integrated machine frame, a plurality of temperature control rollers and a traction roller are arranged on the integrated machine frame in a rotating mode, chemical fibers are wound on the temperature control rollers and the traction roller, and the temperature control rollers and the traction roller are arranged on the integrated machine frame. Heat conduction oil is arranged in the temperature control roller and the traction roller and used for heating the chemical fiber filaments so that the chemical fiber filaments can be conveniently stretched, and the chemical fiber filaments can be heated and stretched after passing through the device. Chemical fibers gradually reach a good stretching stage through segmented heating, and after the chemical fibers are stretched to reach a certain stretching rate, the chemical fibers reach the position of the cooling and shaping roller and make contact with the cooling and shaping roller to be rapidly cooled and shaped.
