Description

Roving frame sliver tension adjusting device Technical Field The utility model relates to the technical field of textile equipment, in particular to a sliver tension adjusting device of a roving frame. Background The cotton sliver is not easy to be too tight or loose when passing through the conveying roller of the roving frame. In the process, tension control of the conveying roller is often needed, so that the second flow of the processed cotton sliver on each part of the continuous production line is ensured to be equal, the requirements of neither stacking nor breaking are met, and the quality of the processed product, such as dimensional accuracy, flatness, winding tightness, appearance, material performance and the like, are ensured to meet the standard requirements. In the case of tension adjustment of the transport rollers of the roving frame, the distance between the transport rollers of the roving frame is generally adjusted, which results in the transport rollers of the roving frame being set to be movable or detachable.
