Description

Technical Field

[0001] This utility model belongs to the field of garment processing technology, specifically, it relates to a bag opening machine material setting adjustment mechanism that facilitates the adjustment of the bag opening size of the fabric. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The conventional approach is to process the pocket opening and the pocket lip separately first, and then sew the pocket lip onto the pocket opening to complete the pocket opening.

[0003] A search revealed that Chinese utility model patent CN212655960U discloses a bag opening material fixing mechanism for garment pocket opening. It includes an outer pressure frame supporting the fabric and a smaller pressure frame for pressing down to clamp and fix the fabric. The smaller pressure frame has a bag opening processing window, and the outer pressure frame has a retractable material fixing window corresponding to the bag opening processing window. The material fixing window is connected to a window adjustment component. The window adjustment component can control the distance between the opposite side walls of the material fixing window, allowing the window to extend and retract in the front-back and left-right directions. Designing the material fixing window to extend and retract in both directions overcomes the limitation of existing material fixing mechanisms that only clamp and fix the fabric. It can exit the gap for sewing after the bag opening is folded, achieving not only fabric fixation but also material fixing for bag opening folding and sewing, making it suitable for automated bag opening equipment.

[0004] However, the applicant discovered the following drawbacks in the above technical solution after research;

[0005] 1. The movement of the left and right telescopic pressure plates and the front and rear telescopic pressure plates relies on the synchronous movement of two sets of cylinders, resulting in a relatively small adjustment range for the left and right telescopic pressure plates and the front and rear telescopic pressure plates, and a limited adjustment range for the material setting window;

[0006] 2. The presser foot in this solution is a single piece of board with a through-hole. Since it is a single piece of board, the size of the through-hole is fixed. If the size of the through-hole needs to be adjusted, the entire presser foot needs to be replaced, which is cumbersome and inefficient.

[0007] There are currently no effective solutions to the problems in the relevant technologies.

[0008] Therefore, in order to solve the above problems, this utility model provides a bag opening machine material setting adjustment mechanism that facilitates the adjustment of the fabric bag opening size. Utility Model Content
