Description

Technical Field

[0001] This utility model relates to the field of garment bag opening processing technology, specifically a bag opening sewing and shaping mechanism for a bag opening machine. 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, then sew the lip onto the opening to complete the pocket opening. The processing of the pocket opening involves cutting, folding, positioning and shaping the lip, and sewing. Cutting involves making a Y-shaped slit at both ends of the pocket opening. Folding involves folding the cut pocket opening inwards to form a flange. Because the pocket opening folds inwards during the folding process, the flange needs to be tucked into the bottom of a small pressure frame to avoid obstruction and interference, thus facilitating the sewing machine's processing.

[0003] Traditional bag opening sewing shaping mechanisms for garments, as described in announcement number CN213061298U, have the following drawbacks: First, the fabric is shaped solely by a single shaping plate, resulting in "Y"-shaped slits at both ends that are prone to warping or bursting, leading to poor shaping and affecting subsequent sewing processes. Second, the shaping plate has a simple structure, making it difficult to adjust to the length or width of the bag opening. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag opening sewing shaping mechanism with a reasonable structure, excellent shaping effect, good stability, and the ability to solve the problem of bursting at both ends during sewing, while also allowing the shaping mechanism to be adjusted to accommodate the bag opening.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A bag opening sewing and shaping mechanism for a bag opening machine includes a mounting frame and a lifting and lowering material fixing connecting plate mounted on the mounting frame. An outer pressure frame device is lifted and lowered on the material fixing connecting plate, and an inner pressure plate device is mounted on the outer pressure frame device. A material fixing window is provided on the outer pressure frame device. The inner pressure plate device includes a driving component, a connecting rod fixed on the driving component, a pressure block assembly slidably engaged at both ends of the connecting rod, and a pressure plate assembly engaged on the pressure block assembly. During shaping, the driving component, through the connecting rod, causes the pressure block assembly and the pressure plate assembly to fit against the material fixing window.

[0007] Preferably, the outer pressure frame device includes a pressure frame that is lifted and lowered on the fixed material connecting plate, a pressure frame cylinder that drives the pressure frame to lift and lower on the fixed material connecting plate, and an outer pressure frame disposed at the bottom of the pressure frame, wherein the fixed material window is fitted on the outer pressure frame.

[0008] Preferably, the drive assembly includes a pressure plate frame that is raised and lowered on the pressure frame, a pressure plate lifting cylinder that drives the pressure plate frame to rise and fall on the pressure frame, and a pressure plate horizontal cylinder that is fitted on the pressure plate frame. A mounting plate is provided between the pressure plate horizontal cylinder and the connecting rod.

[0009] Preferably, the pressure plate assembly includes a front pressure plate and a rear pressure plate that cooperate with each other. The front pressure plate is provided with a front pressure strip that abuts against the material setting window, and the rear pressure plate is provided with a rear pressure strip that abuts against the material setting window. The rear pressure plate is provided with a plurality of adjustment holes, and the front pressure strip and the rear pressure strip are provided with a plurality of positioning holes.

[0010] Preferably, the pressure block assembly includes a connecting seat symmetrically arranged on the connecting rod, a pressure block fixed on the connecting seat, a front positioning member that cooperates with the front pressure bar through a positioning hole, and a rear positioning member that cooperates with the rear pressure bar through a positioning hole, wherein the front positioning member and the rear positioning member are symmetrically arranged at the bottom of the pressure block.

[0011] Preferably, the front positioning member and the rear positioning member are provided with positioning grooves.

[0012] Preferably, the front pressure plate is provided with an adjustment groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The bag opening sewing and shaping mechanism of this practical bag opening machine, with the outer pressure frame device and the inner pressure plate device designed together to form a bag opening sewing cavity with a certain space for sewing processing, replaces the traditional single shaping pressure plate bag opening shaping mode with the outer pressure frame and inner pressure plate working together to shape the material. This solves the problem of bursting at both ends during the sewing process. The layout is reasonable and the bag opening shaping effect is excellent. It also exits before folding the material, ensuring that more folding space is reserved for laser cutting during the folding process, ensuring the stability of the folding.

[0015] 2. The bag opening sewing and shaping mechanism of this practical bag opening machine, with its pressure block assembly and pressure plate assembly, is designed to adapt to the length or width of the bag opening, making it highly adaptable. Furthermore, the pressure block assembly and pressure plate assembly significantly increase the contact surface of the material, preventing wrinkles, ensuring cost efficiency, and providing good stability.
