Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment processing, in particular to a pocket material positioning device for garment bag opening processing. BACKGROUND

[0002] In the garment processing process, the bag opening machine is an essential auxiliary processing machine, which is mainly used to form a pocket at a specific position of the garment to facilitate carrying small items such as mobile phones and wallets. The current practice is to separately process the bag mouth and the bag lip, and then sew the bag lip to the bag mouth to complete the bag opening.

[0003] When processing the bag mouth, the bag mouth needs to be cut and folded, that is, the cut bag mouth is folded inward to form a flange by using a folding knife to press the material window of the frame. The material window is generally composed of two front and rear groups or four front, rear, left and right groups of material positioning pieces that can be extended and retracted (such as the utility model patent No. ZL202020681381.5 discloses a bag mouth material positioning mechanism for garment bag opening). However, most of the material positioning pieces are connected to the outer pressing frame by screws. Each time a pocket of different size is processed, the corresponding size of the material positioning piece needs to be replaced by disassembling the screws, which makes it very inconvenient to replace the material positioning pieces of different sizes. In addition, after replacing the material positioning piece of the corresponding size, in order to ensure that the clamping piece can reliably clamp the folded pocket flange, the corresponding clamping piece also needs to be disassembled and replaced, which further reduces the efficiency of pocket processing.
