Description

Technical Field

[0001] The utility model relates to the technical field of drafting devices, in particular to a frame drafting device which can improve the strength of yarns. Background Art

[0002] Drawing is the process of regularly lengthening and thinning a fiber assembly (such as slivers, rovings, etc.). Its essence is that the fibers are relatively displaced along the axis of the assembly so that they are distributed in longer segments, resulting in a reduction in the linear density of the assembly and further straightening and parallelization of the fibers.

[0003] The patent with publication number CN 212175120 U discloses a novel spinning machine drafting device, which includes a frame, the frame is connected to a wiring box through a support column, the inner side of the wiring box is provided with yarn, the yarn passing through the wiring box is wound around the front drafting roller, the middle drafting roller and the rear drafting roller through a guide roller, and the front drafting roller, the middle drafting roller and the rear drafting roller are all installed on the frame. The device uses a squeezing and flattening mechanism to make the yarn flat and not curled during the drafting process, thereby avoiding the yarn from breaking during the drafting process, which can greatly improve the quality of the yarn. However, the device has the following problems: The extrusion in the extrusion and smoothing mechanism utilizes a driving motor and other structures to move the upper two extrusion and smoothing rollers downward until they are in contact with the lower extrusion and smoothing roller and the fixed roller, thereby extruding the yarn. However, this series of processes are carried out in the wiring box, and it is difficult to accurately control the downward movement distance of the two extrusion and smoothing rollers, and thus it is difficult to accurately control the extrusion and smoothness of the yarn according to requirements. For this reason, a frame drafting device that can improve the strength of the yarn is proposed to solve the problem that the existing yarn drafting device is difficult to adjust the yarn extrusion degree according to the drafting requirements.
