Description

Technical Field

[0001] The utility model relates to the technical field of industrial automation equipment, in particular to a folding mechanism used for industrial automation sewing equipment. Background Art

[0002] The automatic pocket-sticking machine uses a folding device to cold-fold the bag without heating or ironing: that is, a piece of bag is placed on the bag template, and the folding knife on the folding frame of the folding device folds the two sides, front and two corners of the bag root. At this time, the folding frame and the bag template have a simultaneous falling action, pressing the folded bag on the work surface. When the folding knife of the folding frame is retracted and evacuated from the working area, the feeding plate or the receiving plate moves to the top of the bag template and presses down the folded pocket. The bag template finally withdraws, and the folding mechanism rises and resets as a whole to end the folding process. Then, the folded pocket fabric and body fabric are sent to the sewing assembly for sewing through the corresponding feeding device. One folding device usually corresponds to one pocket. Due to different sizes and styles of clothing, the sizes and styles of pockets are diverse, and different equipment needs to be used or the corresponding folding device needs to be replaced. Chinese patent document CN110306302B discloses a folding device for a fully automatic cold folding bagging machine, which has a simple structure and can be quickly disassembled and replaced according to the shape of the pocket to be sewn, greatly improving the production efficiency, helping to reduce production and processing costs, and enabling one machine to sew a variety of pocket shapes, greatly saving the cost of enterprises purchasing multiple devices. However, the corresponding folding knife still needs to be replaced for the same style and different sizes. Utility Model Content
