What's wrong with the button of weft accumulator?

There are many reasons why the buttons don't respond, which may be the damage of internal components or the poor contact and no feedback.

Weft storage device (weft storage device) refers to a temporary storage device for weft before it enters the shed, which is used in rapier looms and gripper looms. It usually consists of a motor, a yarn storage cylinder, a yarn winding disc, a yarn storage detector, a damping ring, a Zhang Liqi and a yarn arranging mechanism.

. By adjusting the position of the photoelectric yarn storage detector, the yarn storage capacity on the yarn storage cylinder is kept within a reasonable range, and the yarn arrangement mechanism makes the yarns on the yarn storage cylinder evenly and neatly arranged. In the process of weft insertion, the rapier or gripper overcomes the resistance generated by the damping ring to pull the weft from the yarn storage cylinder, and the tension of the weft is controlled by Zhang Liqi. The winding speed of the weft accumulator can be adjusted manually or tracked automatically by the control circuit, so that the winding part rotates continuously at low speed and the bobbin unwinds continuously.
