Description

Efficient energy-saving fabric weft straightening machine

Technical Field

The utility model relates to the technical field of printing and dyeing equipment, in particular to a high-efficiency energy-saving fabric weft straightening machine.

Background

Weft straightening machines are machines for correcting the weft thread. In the scouring, bleaching and printing and dyeing processes, the fabric can generate the phenomena of warp extension, weft shrinkage, uneven breadth, uneven selvedge, warp yarn deflection and the like due to the warp tension effect of a plurality of machines. To overcome the above drawbacks, fabrics must be subjected to a weft straightener setting treatment, which is used in large quantities in the textile industry. The weft straightener can lead or lag the corresponding bent part of the weft yarn by adjusting the relative running speed among warp yarns of the fabric, so that the state that the weft yarn and the warp yarn vertically intersect in the full width is restored.

Because the fabric is dyed and then weft-straightened, the whole fabric is in a wet state and can generate twisting, the weft straightening is not facilitated, a plurality of rollers are independently arranged before weft straightening in the prior art, the fabric is unfolded, the structure is complex, the power consumption is large, in addition, the weft straightening effect is determined by checking the fabric after weft straightening through a detector, the detector usually comprises a light source and a probe, the probe senses the light transmitted through the fabric to determine whether the weft is horizontal or not, in the prior art, the light source brightness is constant, the light transmittance of the fabrics with different colors is different due to different light transmittance of different fabric thicknesses, the light source with constant brightness is unfavorable for the detection of the detector, meanwhile, the detection result is also waste of power due to the fact that the light transmittance is too high, and in view of the fact, the high-efficiency energy-saving fabric weft straightening machine is proposed.
