Description

Automatic positioning folding knife mechanism for bag opening machine Technical Field The utility model belongs to the technical field of intelligent sewing equipment, and particularly relates to an automatic positioning folding knife mechanism for a bag opening machine, which is suitable for automatic processing of a folding structure in the working procedures of sewing bags, zippers and the like. Background In the field of clothing processing, a bag opening machine is key equipment for sewing bags, and the key functions of the bag opening machine include bag opening cutting, edge folding processing and sewing shaping. The traditional pocket opening machine is mainly designed with fixed size, the position and the distance of the folding knives are manually adjusted, the efficiency is low, the precision is not enough, and especially when pockets with different sizes or complex pockets with zippers are processed, the pocket opening machine is easy to sew dislocation or fold due to positioning deviation. The bag folding mechanism disclosed in the patent CN202220630108.9 is used for finishing folding through the cooperation of four groups of cloth folding slotting tools and lifting and traversing assemblies, but the bag opening is withdrawn through repeated horizontal traversing, so that the processing time is long, flexible cloth is easy to pull and deform, and the flatness of the bag opening is influenced. The sewing of the zipper pocket has extremely high requirements on positioning precision, and the traditional method needs to manually align the zipper with the pocket mouth, so that the error is often more than +/-2 mm, and the seam is askew or the zipper is blocked.
