Background
The palm threading machine is a high-precision automation device for threading yarns on shaft heads into palm fiber sheets in sequence, the existing palm threading machine can only thread yarns on one shaft head into the palm fiber sheets in sequence, but cannot simultaneously thread the yarns on two shaft heads into the palm fiber sheets in sequence, and the reason is that the device for mutually separating and pushing the yarns on the two shaft heads is not used. The yarns on the two shaft heads penetrate into the palm fiber sheets in sequence, so that the arrangement sequence of different yarns on the palm fiber sheets can be greatly expanded, and the pattern and color change capability of yarn weaving is improved.
