Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a bag opening material setting mechanism used for clothing bag opening processing. Background Art

[0002] In the garment manufacturing process, pocket opening machines are essential auxiliary processing machinery, primarily used to create pockets in specific locations on garments, conveniently allowing for the carrying of small items such as mobile phones and wallets. Conventional methods involve separately processing the pocket opening and lip, then sewing the lip to the opening to complete the pocket opening. The pocket opening process involves cutting, folding, positioning and shaping the lip, and sewing. The folding process involves folding the cut opening inward to form a flap. Since the opening folds inward during the folding process, the flap needs to be scraped into the bottom of a small press frame to avoid obstruction and interference, facilitating the sewing process on the sewing machine.

[0003] The conventional bag-opening material-fixing mechanism of a garment bag-opening machine, such as that described in Publication No. CN216551016U, has the following problems and defects: First, the bottom of the pressure plate is provided with a transverse flanging limiter assembly and a longitudinal flanging limiter assembly to limit the flanging from separating from the pressure plate. The transverse flanging limiter assembly and the longitudinal flanging limiter assembly are used to stably clamp the flanging of the bag under the pressure plate to prevent the flanging from being easily pulled out by inertia when the scraper is withdrawn, thereby interfering with the sewing process of the sewing machine. This structure realizes the flanging clamping function by horizontal push-pull, which has the problems of complex structure, poor stability and high cost. Second, the window adjustment assembly that controls the expansion and contraction of the material-fixing window adopts V-shaped adjustment parts, inclined keyways, etc. to control the opening and closing of the material-fixing window. It also has the problems of complex structure, unreasonable layout, poor stability and high cost. Therefore, further improvement is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a bag opening material fixing mechanism for clothing bag opening processing which has a simple structure, a reasonable layout, good stability and a low cost.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A bag opening material fixing mechanism for clothing bag opening processing includes a pressure plate for supporting fabric, a material fixing window arranged on the pressure plate and used for bag opening processing, and a window adjustment component for controlling the scaling of the material fixing window, the material fixing window includes a front material fixing piece and a rear material fixing piece, the front material fixing piece and the rear material fixing piece are arranged opposite to each other and enclose a material fixing opening, the pressure plate is provided with a clamping assembly for limiting the flanging from separating from the pressure plate, the clamping assembly includes a clamping cylinder arranged on the pressure plate, a flanging splint arranged at the bottom of the pressure plate and an elastic connecting plate cooperated with the flanging splint for driving the splint to rise and fall, the elastic connecting plate is linked to the clamping cylinder, and the flanging splint covers the bottom of the material fixing window.

[0007] Preferably, a fixing plate is connected between the front end of the flanging clamp and the pressure plate, the rear end of the flanging clamp is fixed with the elastic connecting plate, and one end of the clamping cylinder penetrates into the pressure plate and is lifted and lowered with the elastic connecting plate.

[0008] Preferably, the window adjustment assembly includes a front pull rod fixedly connected to the front fixed material piece, a rear pull rod fixedly connected to the rear fixed material piece, and a double-opening cylinder that simultaneously drives the front pull rod and the rear pull rod to reciprocate, the double-opening cylinder includes a cylinder seat fixed on the pressure plate and a front cylinder arm and a rear cylinder arm slidingly fitted on the cylinder seat, the front cylinder arm is fixedly connected to the front pull rod, and the rear cylinder arm is fixedly connected to the rear pull rod.

[0009] Preferably, the pressure plate is provided with limiting grooves for limiting the positions of the front pull rod and the rear pull rod.

[0010] Preferably, a cloth clamping assembly is also provided on the pressing plate, and the cloth clamping assembly includes cloth clamping cylinders arranged on both sides of the pressing plate, cloth clamping rods linked to the cloth clamping cylinders, and transverse cloth clamping plates fixed at the ends of the cloth clamping rods, and the cloth clamping rods are arranged obliquely between the pressing plate.

[0011] Preferably, the pressing plate is provided with a mounting notch at a position corresponding to the front end of the cloth clamping rod.

[0012] Preferably, connecting blocks are symmetrically arranged on the pressing plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This practical bag opening material fixing mechanism replaces the traditional horizontal flanging limit assembly and the longitudinal flanging limit assembly through the design of the clamping assembly, that is, a set of clamping assemblies is used to replace two sets of limit assemblies that pull the flanging back and forth in different directions horizontally between the upper and lower structures of the flanging. This can prevent the flanging from being easily brought out by inertia when the scraper exits, thereby interfering with the sewing process of the sewing machine, and can also ensure a high yield rate, making it more suitable for automated bag opening equipment. While optimizing the structure, it greatly improves the stability performance and reduces manufacturing costs.

[0015] 2. This practical bag-mouth dosing mechanism controls the scaling of the dosing window in a window adjustment assembly that uses a double-opening cylinder to drive a double connecting rod to control the front dosing piece and the rear dosing piece. This not only greatly optimizes the layout, but also improves the coordination of the dosing window, avoiding installation errors caused by complex structures such as V-shaped adjustment parts and inclined keyways. It has good stability, low cost and easy assembly. BRIEF DESCRIPTION OF THE DRAWINGS
