Description

technical field [0001] The invention relates to a sewing machine, in particular to a feeding mechanism of a ribbon sewing machine. Background technique [0002] In the field of shoes, hats, clothing and home furnishing, some webbing loops are usually sewn on the product. For example, we sew webbing loops on the upper of shoes for wearing shoelaces; we sew webbing loops on curtains to facilitate hanging curtains; [0003] Existing webbing ring processing is to manually pull out the rolled webbing by a worker, cut into equal-length webbing segments, then bend the head of the webbing and sew and join the webbing body to form a webbing ring. Since they are all manual operations, the processing quality cannot be guaranteed, and the labor cost is high and the processing efficiency is low. [0004] The invention patent with the patent number of 2013107206049 discloses a ribbon loom, which includes a material guide mechanism, a material stacking mechanism and a material feeding me...

AI Technical Summary

Problems solved by technology

The ribbon loom machine automatically cuts the ribbon into a set length of ribbon through the material guide mechanism, and outputs it to the stacking mechanism, and automatically folds the ribbon through the stacking mechanism to form a ribbon loop, and the feeding mechanism pushes out the last sewn ribbon loop sewing position, and at the same time send the newly folded webbing ring to the sewing position for sewing and fixing, realizing the automatic feeding, cutting, folding, unwinding and sewing of the webbing, but the webbing machine can only convey , fold, and sew a webbing

The left and right sides of the upper need to be sewn with a row of webbing loops for wearing shoelaces. The loom disclosed in this patent cannot realize the simultaneous conveying, folding and feeding of several webbings, so the processing efficiency is relatively low.
