Description

Technical Field

[0001] The invention belongs to the technical field of spinning frames, and in particular relates to a roller segmented transmission device in a whole-section box-type spinning frame. Background Art

[0002] As the market demand for extra-long spinning frames gradually increases, the spinning frames are gradually lengthened, resulting in the gradual lengthening of the middle rollers arranged thereon. Increasing the length of the middle rollers will increase the aspect ratio of the middle roller transmission. A larger aspect ratio of the roller transmission will lead to the occurrence of middle roller torsional vibration, that is, the torsion transmitted by the drafting transmission devices at the head and tail of the spinning frame lags behind at the end of each middle roller. The problem of roller torsional vibration of the middle roller caused by the large aspect ratio of the middle roller transmission is becoming increasingly prominent, which in turn affects the quality of the yarn. Traditional extra-long spinning frames reduce the aspect ratio of the roller transmission by setting an intermediate transmission box, thereby avoiding the occurrence of roller torsional vibration. However, the production cost of the intermediate transmission box is high, and the volume of the box body is large, which will occupy the original spindle space of the spinning frame, resulting in a reduction in the number of spindles of the spinning frame, thereby reducing the output of the spinning frame.
