Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing technology, in particular to a universal bag opening machine pressing frame component. Background Art

[0002] Pocket opening machines are essential auxiliary processing machines in the garment manufacturing process. They are primarily used to create pockets in specific locations on garments, making it convenient for carrying small items such as mobile phones and wallets. Conventional methods involve first separately processing the pocket opening and lip, then sewing the lip onto the opening to complete the pocket opening.

[0003] The pocket opening processing process requires cutting, folding, shaping and sewing the pocket opening of the garment. Cutting means making a "work"-shaped slit on the pocket opening, folding means folding the cut pocket opening inward to form a flap, shaping the lip means placing the lip on the flap, and finally sewing.

[0004] However, existing press frames have four sets of sizing and pulling knives, such as the automated true-pocket making machine described in Chinese Patent Publication No. CN221167014U. Each set of four sizing and pulling knives can only fold pockets of one size. Changing the size of the pockets requires replacing all four sets of sizing and pulling knives. Furthermore, these four sets of sizing and pulling knives are typically designed to produce "Y"-shaped cracks at both ends of the bag opening. For "G"-shaped cracks, however, two sets of sizing and pulling knives would be redundant. This is why the present invention was developed. Utility Model Content

[0019] The present invention provides a universal bag opening machine frame assembly. Figure 1-3 As shown, the machine comprises a frame 1, on which a workbench 11 is mounted. A laser cutting mechanism 2, a sewing mechanism 3, a knife inserting mechanism 4, and a base plate 6 are mounted corresponding to the workbench 1. The frame 1 is also provided with a base plate moving mechanism 10 for moving the base plate 6, and a knife inserting mechanism 5 for moving the knife inserting mechanism 4. The above is prior art. For the structure of a bag opening machine, see the automatic bag opening machine disclosed in Publication No. CN220724510U.

[0020] like Figure 2 As shown, a through slot 61 is provided on the base plate 6, and a material-scaling and drawing assembly 8 is provided on the base plate 6. The material-scaling and drawing assembly 8 includes two sets of drawing knives 81, a first screw guide module 82, a material-scaling knife 83, and a second screw guide module 84. The two sets of drawing knives 81 and material-scaling knives 83 correspond to each other front and back and are located on the front and back sides of the through slot 61. The width of the drawing knives 81 and material-scaling knives 83 is consistent with the length of the through slot 61. The length of the drawing knives 81 and material-scaling knives 83 is the width of the largest "I" type incision.

[0021] The screw slide module 1 82 and the screw slide module 2 84 are existing mature modules that realize the linear drive function and can also be replaced by other modules that can realize linear motion. The rear handle of the pulling knife 81 is connected to the sliding nut of the screw slide module 1 82, and the rear handle of the fixing knife 83 is connected to the sliding nut of the screw slide module 2 84; the screw slide module 1 82 and the screw slide module 2 84 are used to drive the pulling knife 81 and the fixing knife 83 respectively.
