Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to a frame pressing assembly. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The conventional approach is to process the pocket opening and lip separately first, and then sew the lip onto the opening to complete the pocket opening.

[0003] The bag opening process involves cutting, folding, shaping, and sewing the bag opening. Cutting involves making two "Y"-shaped or "I"-shaped slits at the bag opening. Folding involves folding the cut bag opening inward to form a folded edge. Shaping involves placing the bag lip on the folded edge. Finally, the bag is sewn together.

[0004] However, the current bag-opening machine's frame pressing assembly has the following shortcomings: First, the stationary and pull cutters are linearly driven by cylinders, but the cylinder's driving stroke is fixed. If different models of stationary and pull cutters need to be replaced, the cylinder position needs to be adjusted synchronously, which is inefficient and inconvenient. Second, when processing bags of different sizes, the distance between the small and outer frame pressing frames needs to be adjusted. Currently, an adjustable pressing strip is set on the small frame pressing frame, and adjustment is made by locking it with a long strip-shaped positioning hole and bolts. The accuracy of this adjustment method depends on the worker's experience, often resulting in multiple adjustments, which is inefficient and inaccurate. Summary of the Invention

The material positioning assembly is driven by two actuators 8 and four actuators 10. The front material positioning blade 5 and the rear material positioning blade 6 correspond to the front and rear sides of the through groove 2, respectively. In this embodiment, to improve the stability of the front material positioning blade 5 during movement, there are two actuators 8, but it is not limited to two; there can be one or more. The two actuators 8 are symmetrically arranged, and the two actuators 8 are connected to the two ends of the front material positioning blade 5 through connecting rods 12.

A guide rail 20 is vertically arranged on the base plate 1, and a slider 21 that is slidably adapted to the guide rail 20 is arranged on the pressing frame plate 17. The driver 19 can be one of a cylinder, an electric push rod, or a lead screw servo motor. The driver 19 is vertically arranged on the base plate 1 and connected to the pressing frame plate 17 through its output end. Alternatively, it can be vertically arranged on the pressing frame plate 17 and connected to the base plate 1 through its output end.

[0027] The outer pressure frame 15 is set on the pressure frame platform 17 and corresponds to the inner pressure strip 16. The outer pressure frame 15 is U-shaped and the inner pressure strip 16 is straight. The outer pressure frame 15 and the inner pressure strip 16 form a rectangular pressure frame.

[0028] The pressing frame plate 17 is equipped with a drive mechanism for driving the pressing strip plate 18 to move longitudinally.
