Description

Technical Field

[0001] The invention belongs to the technical field of cloth feeding or cloth sorting mechanisms used in sewing pockets, and in particular relates to a self-adaptive and adjustable bag folding device and a bag pasting machine. Background Art

[0002] The pocket folding machine is a pocket sewing device. The user only needs to place the fabric to complete the pocket folding action and sew the folded pocket on the shirt or pants. The production efficiency of the pocket folding machine is about three times that of manually sewing pockets.

[0003] When the pocket sticking machine is sticking pockets:

[0004] First, the user places the pocket fabric piece on the bag mold. At this point, the pocket fabric piece covers the bag mold, leaving excess fabric on the left, right, and bottom of the bag mold that needs to be folded. This fabric hangs down due to gravity.

[0005] Then, the pressing plate of the bag folding mechanism presses the pocket cloth piece to prevent the pocket cloth piece from deviating during the bag folding process;

[0006] Then, the folding knives of the bag folding mechanism move in sequence to fold the sagging fabric under the bag mold;

[0007] Finally, the folded pocket is pressed down onto the shirt or trousers, and the folding knife and pressing plate of the bag folding mechanism are reset.

[0008] In performing the above-mentioned action, the bag mold and the folding knife need to be adapted to complete the bag folding action. However, in the existing technical design, the folding knife is driven by a cylinder and can only be used for pockets of one size. When it is necessary to fold pockets of different sizes, in addition to replacing the bag mold, the position of the folding knife needs to be manually adjusted. The debugging time varies depending on the user's proficiency. Summary of the Invention
