[0010] The power assembly drives the large sprocket to rotate by a certain angle to adjust the fabric inlet distance or the fabric outlet distance.

[0011] The technical problems to be solved by the utility model can also be implemented by the following technical scheme, the mechanical weft straightening device of the tentering setting machine, the cloth feeding roller and the cloth discharging roller are symmetrically arranged on the two side walls of the rack.

[0012] The technical problems to be solved by the utility model can also be implemented by the following technical scheme, the mechanical weft straightening device of the tentering setting machine, the cloth feeding roller and the cloth discharging roller are symmetrically arranged on the two side walls of the rack.

[0013] Compared with the prior art, the utility model has the beneficial technical effects that:

[0014] (1) the device is different from the direct transmission of the conventional reduction motor, chain transmission is increased in the later stage of the reduction motor, the total speed ratio can be improved, and the weft straightening angle can be flexibly adjusted;

[0015] (2) and no frequency converter is needed, which helps to reduce the equipment cost, when the cloth feeding distance or the cloth discharging distance needs to be adjusted, only the large sprocket needs to be rotated, the height of the cloth guide roller I and the cloth guide roller II can be changed, and the height of the woven cloth is almost the same as the cloth feeding roller and the cloth discharging roller.
