Description

Adaptive Adjustable Bag Folding Device and Bag Sealing Machine Technical Field

[0001] This invention belongs to the technical field of fabric feeding or feeding mechanisms used in sewing pockets, and particularly relates to adaptive adjustable folding pocket devices and pocket attaching machines. Background Technology

[0002] A pocket-making machine is a device for sewing pockets. Users only need to place the fabric to complete the folding action and sew the folded pocket onto a shirt or trousers. The production efficiency of a pocket-making machine is about three times that of manually sewing pockets.

[0003] When the bag-applying machine is applying the bag:

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

[0005] Then, the pressure plate of the folding mechanism presses the pocket fabric to prevent it from shifting during the folding process;

[0006] Next, the folding blades of the folding mechanism fold the drooping fabric under the bag mold in sequence;

[0007] Finally, press the folded pocket down onto the shirt or trousers, and reset the folding blade and pressure plate of the pocket folding mechanism.

[0008] In performing the above actions, the bag template and the folding knife need to be compatible to complete the bag folding action. However, in the existing technology design, the folding knife is driven by a cylinder and can only be used for one size of bag. When it is necessary to fold bags of different sizes, in addition to changing the bag template, it is also necessary to manually adjust the position of the folding knife. The adjustment time varies depending on the user's proficiency. Summary of the Invention
