Description

Technical Field

[0001] The utility model relates to the technical field of setting machines, in particular to a disc weft straightening device of a hot air stentering setting machine. Background Art

[0002] In the stenter setting machine, the weft straightener is also an important component. At present, four sets of sensors are often configured on a weft straightener at the same time. Each set of sensors includes two parts, the light-emitting part and the light-sensitive part. The weft skew of the cloth can be detected through the photoelectric effect, and the action part is driven by a hydraulic system.

[0003] The patent with the publication number CN213203499U discloses a disc weft straightening device of a hot air stenter setting machine, which includes a left frame and a right frame. A first roller is arranged at the upper left end of the left frame, a second roller is arranged at the lower right side of the first roller, a third roller is arranged at the upper right side of the second roller, and a fourth roller is arranged at the lower right side of the third roller. The device arranges the oblique weft layer by layer by arranging five rollers to obtain a complete yarn weft. The rollers are driven by gears and belts for transmission. The entire weft straightening device only needs two drive motors for power output, which greatly saves costs.

[0004] However, the device has the problem that after guiding the weft yarn to the first roller, the driving motor passes through the first roller, the second roller, the third roller, the fourth roller and the fifth roller to straighten the weft yarn. However, the rollers in the disc weft straightening device can rotate, and the distance between the two rollers is fixed. However, the thickness and width of the weft yarn required for weft straightening in real life are uncertain, and thus the rollers with fixed spacing are difficult to effectively straighten weft yarns of different thicknesses. Therefore, a disc weft straightening device for a hot air stentering and setting machine is proposed to solve the problem that the existing disc weft straightening device is difficult to effectively straighten the weft yarn according to the thickness of the weft yarn.
