The principle of this embodiment is:

Through practice, it has been found that the problems of hair loss and deformation in general wig knitting machines, resulting in high defective rate, are mainly due to the setting of the driving, driven wheels and transmission belts of general wig knitting machines, and the speed ratio is certain. Tuning can only adjust the overall rate, but their relative rates are not easy to adjust.

To solve such a problem, the basic mechanism 100 for dispatching cars in this embodiment can realize the adjustment of the relative speed between the first pinch wheel assembly and the second pinch wheel assembly by means of the shifting transmission assembly.

The transmission unit that the pinch wheel assembly cooperates keeps the position of the elastic transmission belt 53 unchanged, otherwise the transmission unit that is matched with the second pinch wheel assembly can be adjusted to keep the elastic transmission belt 53 of the transmission unit that is matched with the second pinch wheel assembly. The position is unchanged.

The adjustment of other gears can also refer to the above-mentioned method, so that the total speed is not simply adjusted, so that the relative speed between the first pressure wheel 314 and the second pressure wheel 334 is adjusted to a suitable gear, avoiding It leads to hair loss or deformation of the product, which ultimately reduces the defective rate of the product.
