Description
Technical Field
[0001] This utility model belongs to the technical field of garment sewing equipment, specifically a quick-assembly structure for the pressing frame of a patching 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 third pressure frame locking cylinder 19 drives the third locking element to move downwards, locking and securing the third pin 16, which is installed inside the inner pressure frame mounting base 18. The fourth pressure frame locking cylinder 20 drives the fourth locking element to move downwards, locking and securing the fourth pin 17, which is installed inside the inner pressure frame mounting base 18.
[0032] When it is necessary to replace or disassemble the inner pressure frame 13, the third pressure frame locking cylinder 19 drives the third locking component to loosen the third pin 16, and the fourth pressure frame locking cylinder 20 drives the fourth locking component to loosen the fourth pin 17, thus removing the original inner pressure frame 13. Then, the inner pressure frame 13 to be installed is inserted into the inner pressure frame mounting base 18, and the above locking action is repeated to achieve quick disassembly and installation of the inner pressure frame 13.
[0033] like Figure 3 and Figure 4As shown, an inner pressure frame adjusting cylinder 21 is provided on the inner pressure frame mounting base 18. The drive rod of the inner pressure frame adjusting cylinder 21 is connected to an adjusting push plate 22, which is connected to the inner pressure frame 13 below it.

[0035] The inner pressure frame mounting base 18 is connected to a guide plate 25, which is located between the adjusting push plate 22 and the inner pressure frame 13. The guide plate 25 has a first guide groove 25a, a second guide groove 25b, and a third guide groove 25c. A first screw passes through the first guide groove 25a, a second screw passes through the second guide groove 25b, and a third screw passes through the third guide groove 25c.
[0036] The drive rod of the inner pressure frame adjusting cylinder 21 drives the adjusting push plate 22 to move forward or backward relative to the guide plate 25. The adjusting push plate 22 drives the first screw to move in the first guide groove 25a, the second screw to move in the second guide groove 25b, and the third screw to move in the third guide groove 25c. The first screw drives the left pressure plate 13a to move, the second screw drives the right pressure plate 13c to move, and the third screw drives the front pressure plate 13b to move. That is, the inner pressure frame adjusting cylinder 21 drives the left pressure plate 13a, the front pressure plate 13b, and the right pressure plate 13c to open outward or close inward.
