Description
Technical Field
[0001] This utility model belongs to the field of sewing equipment technology, specifically a bag folding device for a fully automatic bag attaching machine. Background Technology
[0002] Pocket applicators are primarily used for sewing pockets on jeans, shirts, and other garments. They can complete both straight stitching and buttonhole stitching in one pass and are also suitable for sewing irregularly shaped areas in garment processing. Existing pocket applicators are mainly divided into semi-automatic and automatic types, the main difference being the application of wrinkle-free folding technology. Semi-automatic pocket applicators require an electrically heated steam folding machine next to the main machine. The folded pocket opening is placed on the feeding section of the applicator for conveying and sewing, which is not only costly but also inefficient. Automatic bag-sealing machines directly perform wrinkle-free folding of the bag shape using a folding device: a bag piece is placed on the bag-shaped template, and the folding blades on the folding frame of the folding device fold the sides, front, and two corners at the base of the bag piece. At this time, the folding frame and the bag-shaped template fall simultaneously, pressing the folded bag shape onto the worktable. After the folding frame blades retract and leave the work area, the feeding plate or receiving plate moves to the top of the bag-shaped template and presses down on the folded bag. Finally, the bag-shaped template retracts, and the folding mechanism rises and resets to end the bag-folding process.
[0003] The existing automatic bag-applying machines suffer from poor accuracy and stability in bag application because the bag folding frame and bag template are suspended in the air to complete the folding action. This can easily lead to misalignment, resulting in unstable bag application quality and low work efficiency. Summary of the Invention
[0004] This utility model addresses the aforementioned technical problems by providing a bag-folding device for a fully automatic bag-applying machine, which can achieve precise bag application and ensure that the bag does not deform or misalign.
