Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to an integrated presser foot assembly for hemming and pleating. Background Technology

[0002] In garment production, hemming and pleating are often applied independently. However, combining these two processes in one go is unprecedented in the market and extremely difficult. To successfully complete this process, the following five steps must be followed, using a 1-meter length as an example: 1. First, lay the positioning line (for the hemmed area), taking 1 minute; 2. Perform the hemming operation, taking 3 minutes; 3. Perform the pleating separately, taking 5 minutes; 4. Sew the hemmed area to the center of the pleat, taking 10 minutes; 5. Remove the previous hemming and positioning lines, taking 16 minutes, for a total of 35 minutes. Furthermore, during the seam removal process, it was found that this not only takes a long time but also affects the pleating effect, resulting in an unattractive quality that is unacceptable to customers. Summary of the Invention

[0018] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.

[0019] Example:

[0020] This embodiment provides an integrated presser foot assembly for hemming and pleating, such as... Figures 1 to 4As shown, the device includes a pressure plate body and a feed dog 4. The pressure plate body includes a connecting rod 1, an upper pressure plate 2, and a lower pressure plate 3. The lower end of the connecting rod 1 is connected to the first end of the upper pressure plate 2. A stop block 8 is provided at the lower part of the first end of the upper pressure plate 2. A hemming tongue 9 and a presser foot plate 10 are provided at the second end of the upper pressure plate 2. A feed notch 11 is formed between the hemming tongue 9 and the presser foot plate 10. A hemming element 5 is provided in the feed notch 11. The presser foot plate is longer than the hemming tongue. The hemming element 5 spirals upward and then downward from the end of the presser foot plate to the beginning of the hemming tongue. The lower pressure plate 3 is located below the upper pressure plate 2 and is slidably connected to the upper pressure plate 2. A material passage gap is formed between the lower pressure plate 3 and the upper pressure plate 2. A needle hole 12 is provided on the upper pressure plate 2 in the area between the stop block and the lower pressure plate 3. The feed dog 4 is located below the pressure plate body.

[0021] Furthermore, the stop block 8 is positioned below the material passage gap between the upper pressure plate 2 and the lower pressure plate 3 but above the lower pressure plate 3. The feed dog 4 has a first platform and a second platform, with the first platform corresponding to the stop block 8 and positioned higher than the second platform. Both the first and second platforms are equipped with teeth. In use, the upper fabric enters through the feed notch 11 and is hemmed by the hemming piece 5. Simultaneously, the lower fabric, under the action of the teeth on the second platform, passes through the material passage gap between the lower pressure plate 3 and the feed dog 4, and is pleated by the stop block 8. When the two fabric pieces pass through the needle hole 12 of the pressure plate body, they are sewn together by the sewing machine's needle and thread. The hemming and pleating processes are completed simultaneously in one sewing process. Finally, the first platform, in conjunction with the stop block, feeds out the hemmed and pleated fabric.

[0022] Furthermore, the lower pressure plate 2 is vertically upwardly positioned on the side corresponding to the pressure foot plate 10, with at least two screws 13. A height limiting member 6 is fitted onto each screw 13, and a nut 7 is located at the upper end of each screw 13. The pressure foot plate 10 has a strip groove, and the lower pressure plate 3 is slidably positioned within this groove via the screws 13. Various height limiting members 6 are available, each with a different height. These members are located between the lower pressure plate 3 and the upper pressure plate 2 to adjust the material feed gap. The nut 7 is screwed onto the screw 13, and the nut 7 and the height limiting member 6 clamp the upper pressure plate 2, fixing it to the lower pressure plate 3. The relative positions of the upper and lower pressure plates can be adjusted using the screws and the strip groove, thereby changing the gap between the lower pressure plate 3 and the stop block 8 to achieve different degrees of pleating. Additionally, by selecting height limiting members of different heights, the material feed gap between the upper and lower pressure plates 2 and 3 can be altered to accommodate fabrics of varying thicknesses.

[0023] Furthermore, it also includes a guide plate, which comprises an upper plate and a lower plate, with a guide gap between the upper and lower plates and a notch between the upper and lower plates that matches the presser foot body. In use, the guide plate is set at the feed end of the presser foot plate. The upper fabric directly enters the feed notch 11, and the lower fabric enters the material passage gap between the lower presser plate 3 and the feed dog 4 through the guide gap.

[0024] The integrated hemming and gathering presser foot assembly in this embodiment not only simplifies the hemming and gathering processes in garment production, improving production efficiency, but also reduces additional operations such as unraveling due to the merging of the two processes, thereby ensuring the gathering effect and improving product quality. Furthermore, the assembly has a reasonable structural design, is easy to manufacture and maintain, and has broad application prospects.
