Description

Technical Field

[0001] The utility model belongs to the field of clothing processing machinery, and more specifically relates to a small pressing frame module for a bag opening machine. Background Art

[0002] In the process of garment processing, the bag opening machine is an indispensable auxiliary processing machine. The conventional method is to process the bag opening separately; the bag opening processing process requires cutting, folding and sewing the bag opening of the garment; cutting means making a "Y"-shaped crack at both ends of the bag opening; folding means folding the cut bag opening inwards to form a flange.

[0003] Among them, the compression and positioning function of the large pressure frame and the small pressure frame are indispensable in the processes of cutting, folding and sewing the bag opening; for example, a Chinese patent with an application date of December 26, 2020 and patent number CN202023039502.5 discloses a material taking and fixing device for a clothing pocket opening machine, including a sliding table for sliding installation on the pocket opening machine, and a large pressure frame and a small pressure frame are arranged on the sliding table for lifting and lowering. The large pressure frame is arranged on the lower side of the clothing fabric to support the fabric, and the small pressure frame is arranged on the upper side of the large pressure frame. When working, the small pressure frame is closed to the large pressure frame to fix the clothing fabric.

[0004] However, the existing small pressing frame needs to press the zipper when pressing the material. The zipper is placed on the upper end of the fabric. After the small pressing frame presses the zipper, it may not be able to press the fabric, because the zipper has thickness. The small pressing frame is generally made of an integral piece. In order to ensure that it can press both the zipper and the fabric, it needs to be deformed to a certain extent. The deformation is formed by the pressing force and the toughness of the material itself. Therefore, it cannot be completely guaranteed that the fabric can be pressed, which will cause the zipper or fabric to shift during sewing. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a small pressing frame module for a bag opening machine, which can achieve the effect that both cloth and zipper can be pressed tightly.
