Description

Automatic roving tension adjusting device on roving frame

Technical Field

The utility model belongs to the technical field of roving frame processing, and particularly relates to an automatic roving tension adjusting device on a roving frame.

Background

A roving frame is a spinning machine for making a fiber sliver into roving. The roving frame mainly plays a role in drafting and twisting, and winds the roving into a certain package to meet the processing requirements of the spinning frame. The roving frame is divided into a flyer roving frame and a twisting roving frame in the form of a twisting mechanism. The flyer roving frame rotates by means of flyer to continuously apply twist to the sliver so as to produce twisted roving. The twist roving frame clamps and twists the yarn by a pair of twist leather plates, and forms a false twist with alternate forward and reverse directions on the yarn to produce untwisted roving. The flyer roving frame and twist roving frame can be divided into a first channel, a second channel and a single-way roving frame. The feed pattern, roving package and number of spindles in the machine vary from roving frame to roving frame, but the machine configuration and operation are substantially the same.
