Description

Technical Field

[0001] The utility model relates to the field of twisting machine parts, in particular to a compact twisting station structure and a vertical overfeeding mechanism. Background Art

[0002] An overfeed mechanism is a yarn feeding device used in spinning, twisting, and other production processes. The yarn is wound around a specially treated overfeed roller. A transmission mechanism rotates the roller, delivering the yarn to a spooling device, which then winds the yarn onto a bobbin driven by a take-up roller. Currently, there are two main transmission methods for overfeed rollers: one connects each roller to a separate overfeed motor, allowing each roller to be driven by its own motor; the other uses a single motor to drive an overfeed shaft, mechanically enabling individual overfeed operations. This latter transmission method offers cost savings. Currently, the common overfeed mechanism, driven by an overfeed shaft, typically has the axis of the overfeed roller parallel to the plane of the workstation. Due to the large size of the overfeed roller transmission mechanism and the need for the yarn guide hook to be located centrally within the workstation, the overfeed mechanism's size dictates the spacing between individual workstations, limiting the ability to achieve compact design. This limits the distance between the two overfeed mechanisms, making existing transmissions difficult to meet in applications requiring a specific length in the twisting machine body and spindle spacing.
