Description of the Invention: [Technical Field] The present invention relates to a control mechanism for differential feed of a sewing machine, and more particularly to a control mechanism for back-slitable and differential feeding. [Prior Art] With the continuous development of materials technology and the improvement of economic standards, people are more and more comfortable and beautiful, especially in the sewing process of leather products such as bags, handbags and shoes. The complex design has led to improvements in the sewing method. There are two types of feeding machines that can realize differential feeding: tooth feeding and wheel feeding. The former mainly uses the feed amount of the forward feeding tooth and the feeding amount of the backward moving tooth to be the same or more (commonly known as difference The ratio is to produce different effects of flattening or wrinkling of the sewn surface; the latter is mainly used by the upper and lower feeding wheels and the sewing machine needle to change the relative movement speed of the upper and lower feeding wheels to achieve the flat surface of the rutting surface or Different effects of wrinkles. Although both the tooth feeding and the wheel feeding can realize the differential feeding of the sewing machine, the material is in surface contact with the moving tooth during the tooth feeding, and the material is in point contact with the feeding wheel during the wheel feeding, so the wheel is used. Feeding makes it easier for the operator to manipulate the sewing machine flexibly, resulting in a more ideal seaming effect and design. The conventional conventional wheel feeding adopts a one-way overrunning clutch, and the differential ratio can be adjusted by changing the proportion of the connecting rod based on the center of the circle, but such a model has no reverse stitching function. In addition, if the sewing needle is used to feed the feed roller synchronously: the needle will be under the needle plate 5 201009152 to produce the sewing needle to pin the material, and at this time, the step will cause the secret wheel to have no rubbing and different needles. Content] Good consequences.
