Description
Technical Field
[0001] The utility model relates to the technical field of clothing processing, in particular to a sewing double-flanging mechanism. Background Art
[0002] Sewing double flanging is a common and important process in the garment manufacturing and fabric processing industries. Traditionally, double flanging operations are mostly performed manually, which is not only inefficient but also difficult to ensure quality. This is especially true when dealing with complex shapes and large-scale production, where the limitations and costs of manual operation are particularly prominent. To improve production efficiency and product quality, the automation and mechanization of double flanging systems have become an inevitable trend in the industry.
[0003] However, existing automated sewing equipment is mostly designed for single flanging or sewing tasks and lacks mechanisms that can efficiently and accurately perform double flanging operations. These machines often lack effective control over the folding and positioning of the fabric, resulting in suboptimal flanging results and even requiring manual re-processing. Utility Model Content

[0007] Furthermore, the first wire drum and the second wire drum are both slidably connected to the base via guide rails.
[0008] Furthermore, the double-flanged module includes a carrying platform, a first cloth supporting assembly, a second cloth supporting assembly, a base plate, a reserved slot, a second cylinder and a support arm. The carrying platform is installed on the driving end of the fourth driving module. The reserved slot is opened through the middle of the carrying platform and the base plate. The first cloth supporting assembly and the second cloth supporting assembly are symmetrically installed inside the carrying platform.
[0009] Furthermore, the first cloth-supporting assembly includes a slide, a first cylinder, a slide, a drive plate and shovel teeth.

The driving pulley is installed at the driving end of the driving motor 32. The driven pulley is mounted on the end of the screw rod 34, and the belt is sleeved on the outside of the master and driven pulleys. The outer surface of the screw rod 34 is provided with two opposite threads, namely a forward thread and a reverse thread, wherein the first wire drum 37 is connected to the forward thread, and the second wire drum 38 is connected to the reverse thread. The first lower pressing plate 39 and the second lower pressing plate 310 are correspondingly mounted on the bottom ends of the first wire drum 37 and the second wire drum 38, and the pressing teeth 311 are integrally connected to the bottom ends of the first lower pressing plate 39 and the second lower pressing plate 310. In addition, the first wire drum 37 and the second wire drum 38 are both slidably connected to the base 31 through guide rails;
[0030] The double-flanging module 6 is composed of a carrying platform 61, a first cloth-supporting assembly 62, a second cloth-supporting assembly 63, a bottom plate 64, a reserved slot 65, a second cylinder 66 and a support arm 67, wherein the carrying platform 61 is mounted on the driving end of the fourth driving module 5, the reserved slot 65 is a rectangular slot that passes through the middle of the carrying platform 61 and the bottom plate 64, the first cloth-supporting assembly 62 and the second cloth-supporting assembly 63 have the same structure, and are symmetrically mounted inside the carrying platform 61 with the reserved slot 65 as the center, the second cylinder 66 is mounted on the upper part of the carrying platform 61, and is distributed corresponding to each corner of the reserved slot 65, and the support arm 67 is mounted on the telescopic end of the second cylinder 66;
[0031] The first cloth-supporting assembly 62 is composed of a slide 621, a first cylinder 622, a slide 623, a drive plate 624 and a shovel tooth 625, wherein the slide 621 and the first cylinder 622 are both installed on the upper part of the supporting platform 61, the slide 623 is slidably set on the upper part of the slide 621, and is connected to the telescopic end of the first cylinder 622, the drive plate 624 is installed at the bottom end of the slide 623, and the shovel tooth 625 is set at the end of the drive plate 624. It should be noted that the shovel tooth 625 and the pressing tooth 311 are staggered.
[0032] When using the double-flanged sewing mechanism, please refer to Figure 9-12 , follow these steps:
[0033] S1. The staff spreads the cloth on the carrying platform 61. It should be noted that a cloth opening is reserved in the middle of the cloth. After the cloth is spread, it corresponds to the position of the reserved slot 65.
[0034] S2: The first lower pressing plate 39 and the second lower pressing plate 310 move downward synchronously, so that the pressing teeth 311 of the two move downward synchronously, enter from the position of the cloth opening, and make the cloth begin to fold toward each other at the position of the opening;
[0035] S3, the first lower pressing plate 39 and the second lower pressing plate 310 are moved away from each other. Since the pressing teeth 311 protrude from the first lower pressing plate 39 and the second lower pressing plate 310, when the two are moved away from each other, the protruding portion of the pressing teeth 311 will lift the folded portion of the fabric.
[0036] S4, the two driving plates 624 and the shovel teeth 625 on both sides will be close to each other. Because the shovel teeth 625 and the pressing teeth 311 are staggered with each other, the shovel teeth 625 will enter the gap between the pressing teeth 311 (similarly, the pressing teeth 311 will also enter the gap between the shovel teeth 625). At this time, the folded part of the cloth is jointly supported by the shovel teeth 625 and the pressing teeth 311. Then, the first lower pressing plate 39 and the second lower pressing plate 310 drive the pressing teeth 311 to move synchronously toward the middle. After moving, only the folded part of the cloth is supported by the shovel teeth 625. Then, the first lower pressing plate 39 and the second lower pressing plate 310 drive the pressing teeth 311 to move upward synchronously. The part is then transferred to the sewing equipment for sewing and fixing, thereby achieving the effect of double flanging.
