Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and more particularly to a sewing equipment for preventing down leakage from down jackets. Background Technology

[0002] Down jackets are warm garments made by filling down with the feathers of waterfowl such as ducks and geese and covering them with fabric. They have excellent warmth retention and can protect people from low temperatures in cold weather. They are a common type of clothing in winter. Sewing equipment is a type of specialized machinery used to make down jackets. There are various types of sewing machines, each with different functions, which work together to ensure the quality and efficiency of down jacket production. For example, industrial sewing machines are used to sew the main body of down jackets, such as splicing the garment pieces and connecting the sleeves to the body, ensuring that the stitches are even and strong.

[0003] In existing down jackets, down feathers tend to escape from the seams during wear. This not only damages the internal filling structure of the down jacket, leading to uneven distribution of the insulation layer and reduced warmth, but also causes down loss, reducing the actual filling amount and affecting the quality and usability of the down jacket. After long-term use, the jacket may become thinner in some areas and its warmth may decrease significantly.

[0004] Therefore, in response to the existing problem that down feathers can easily escape from the seams of clothing, leading to uneven distribution of the insulation layer, reduced warmth performance, and decreased actual filling volume, resulting in thinner areas of the down jacket and affecting its quality and usability, down jacket anti-down-leakage sewing equipment can be designed to ensure a tight fit at the seams and prevent down feathers from escaping.

[0013] The beneficial effects of this invention are as follows: By precisely positioning and pressing the garment with the edge-pressing component, working in conjunction with the overlock machine, the sewing process is optimized, effectively reducing sewing gaps. The subsequent pressing component heat-presses the sewn area, further enhancing the seal. This effectively prevents down from escaping during use, ensuring even distribution of down inside and maintaining the garment's warmth. It avoids localized decreases in warmth due to down leakage, significantly improving the overall quality and stability of the product. Down garments treated with this process exhibit excellent down-proof performance, meeting consumer demand for high-quality down garments and attracting more buyers, thus significantly enhancing the product's market competitiveness. It effectively prevents down leakage, avoiding damage to the down filling structure. This allows the internal filling structure to remain stable over a long period, reducing the decrease in warmth and garment damage caused by damage to the filling structure, thereby extending the lifespan of the down garment and providing consumers with longer-lasting value. It also reduces resource waste, aligning with the concept of sustainable development. Attached Figure Description

A second cylinder 404 is sleeved inside the second circular telescopic sleeve 402. A heating plate 405 is fixedly connected to the lower end of the second cylinder 404. A heat-conducting plate 407 is fixedly connected to the lower end of the heating plate 405. The garment is placed on the support platform 1, directly below the overlock machine body 101 on the support platform 1. According to the sewing requirements, the pressing assembly moves to a suitable position away from the overlock machine body 101 and presses the garment. It works in conjunction with the overlock machine body 101 to perform the sewing operation. Then, the pressing assembly is activated to heat-press and bond the sewn area of ​​the garment, thereby preventing down feathers from coming out of the garment.

[0022] Please see Figure 2 In this embodiment, the upper end of the support platform 1 is fixedly connected to the side away from the pressing component. A rectangular groove 102 is opened on the upper part of the support platform 1 corresponding to the pressing component. The pressing component is used to sew the garment.

[0023] Please see Figure 1 and Figure 3 In this embodiment, the winding assembly includes a support plate 201, a drive motor 202, a rotating column 203, an insertion hole 204, an elastic pressure rod 205, and an insertion rod 206. The drive motor 202 is mounted on one side of the support plate 201. The output end of the drive motor 202 is fixedly connected to the rotating column 203. The end of the rotating column 203 away from the drive motor 202 has an insertion hole 204. An elastic pressure rod 205 is provided above the rotating column 203. The lower end of the elastic pressure rod 205 is fixedly connected to the insertion rod 206. The insertion rod 206 is positioned and connected to the rotating column 203 through the insertion hole 204. Driven by the drive motor 202, the rotating column 203 rotates, and in coordination with the sewing speed, the garment is rolled up at a uniform speed.

[0024] Please see Figure 4In this embodiment, the threaded rod 302 is rotatably mounted on the support platform 1 via a bearing and is arranged along the extension direction of the rectangular slide groove 102. The upper end of the first circular telescopic sleeve 305 is equipped with a first cylinder 306. The output end of the first cylinder 306 is fixedly connected to the first cylinder 307. According to the sewing requirements, the threaded rod 302 is rotated by the drive of the rotating motor 301, so that the rectangular threaded sleeve 303 drives the first L-shaped support column 304 to move along the rectangular slide groove 102. Driven by the first cylinder 306, the first cylinder 307 drives the pressure plate 308 to move downward along the first circular telescopic sleeve 305.

Then, according to sewing requirements, rotate the threaded rod 302 driven by the rotating motor 301. This causes the rectangular threaded sleeve 303 to move the first L-shaped support column 304 along the rectangular slide groove 102, moving the pressure plate 308 to a suitable position relative to the overlock machine body 101. Then, driven by the first cylinder 306, the first cylinder 307 moves the pressure plate 308 downwards along the first circular telescopic sleeve 305, pressing the garment. Finally, start the overlock machine body 101, and the pressure plate 308 will cooperate to... During the sewing operation, the power module 406 is activated, and the heating wire inside the heating plate 405 is energized to start radiating heat, causing the temperature of the heat-conducting plate 407 to rise. Then, driven by the second cylinder 403, the second cylinder 404 moves downward along the second circular telescopic sleeve 402, which facilitates the heat-conducting plate 407 to heat-press and bond the sewn part of the garment, thereby preventing down feathers from escaping from the garment.
