Trouble resolution of beating up shaft part and let-off part

Trouble resolution of beating up shaft part and let-off part

1. Beating up shaft part

It's easy to accumulate waste yarn at the waterproof shield od the swing shaft, causing damage to the bearing, which results in poor beating with abnormal noises and the machine stops cloth defects. Please refer to the HW maintenance manual for solutions.

The fixed bolt reed seat is fastened by electric wrench, which is easy to loosen.

2.Let-off part

1. There are weft defects in the fabric, the adjustment methods are:

A. The'tilt angle' of the light fabric back beam roller should be smaller and the tension should be reduced appropriately.

B. Free spring compression turns to 5 turns or reduce weight iron block.

2. Heavy fabrics have defects in weft direction.

 Adjustment method: increase the weight of the iron block, increase the tilt angle of the rear beam roller and increase the tilt angle of the rear beam roller and increase the tension, if the adjustment is effective, you can continue to increase the adjustment intensity. If there is no change in the adjustment to fabric defects, it is necessary to carefully check the gears, warp guide bearings warp beam bearings, and let-off gear box for accessories wear.

3.warp beam bearings are prone to wear under high warp tension. 

Solution: Try to reduce the warp tension of the fabric and the special fabric with large heavy tension needs to increase the warp beam bearing. In addition, the solution to the warp breakage: change the warp tension, control the temperature and humidity on the spot, and warp hanging slurry Uniform, adjust the number of free spring compression turns, and change the tilt angle of the rear beam. If there is no improvement, you need to check the equipment: heald wire, steel reeds, finish of guide tube.
