Description

Technical Field

[0001] This utility model belongs to the technical field of garment sewing equipment, specifically a quick-assembly structure for a bag-applying machine. Background Technology

[0002] Automatic bag-sealing machines directly perform heat-free, iron-free cold folding of the bag shape using a folding device: a bag piece is placed on a bag template, and the folding blade on the folding frame of the folding device folds the sides, front, and two corners at the base of the bag piece. Simultaneously, the folding frame and the bag template descend, pressing the folded bag onto the worktable. After the folding frame and blade retract and leave the work area, a feeding or receiving platen moves above the bag template and presses down on the folded bag. The bag template then retracts, and the entire folding mechanism rises and resets, ending the folding process. The folded pocket fabric and body fabric are then fed to the sewing assembly for sewing via a corresponding feeding device. The feeding device typically includes a pocket presser foot for pressing the pocket fabric and a body presser foot for pressing the body fabric. A sewing gap corresponding to the shape of the pocket is maintained between the body presser foot and the pocket presser foot.

[0003] In existing automatic bag-attaching machines, the body presser foot and pocket presser foot are usually fixed in their corresponding positions with bolts and other fasteners. However, based on actual production needs, the body presser foot and pocket presser foot will be replaced according to the actual sewing requirements. At this time, it is necessary to unscrew each bolt, remove the corresponding presser foot part, align the new presser foot part with the corresponding position, and then tighten the bolts to fix it. This operation is cumbersome. Summary of the Invention

The fourth locking cylinder 17 drives the fourth locking block 19 to move downward, and the fourth locking block 19 abuts against the upper surface of the fourth pressure frame mounting block 14 and locks it in place.

[0025] When it is necessary to replace or remove the inner pressure frame 12, the third locking cylinder 16 drives the third locking block 18 to release the third pressure frame mounting block 13, and the fourth locking cylinder 17 drives the fourth locking block 19 to release the fourth pressure frame mounting block 14, thus removing the original inner pressure frame 12. Then, another inner pressure frame 12 is installed into the inner pressure frame mounting seat 15, and the above locking action is repeated to achieve quick removal and installation of the inner pressure frame 12.

[0026] An inner pressure frame adjusting cylinder 21 is provided on the upper surface of the third base 15a of the inner pressure frame mounting base 15. The drive rod of the inner pressure frame adjusting cylinder 21 is connected to the adjusting push plate 22. The adjusting push plate 22 is connected to the inner pressure frame 12 below it.
