Description

Technical Field

[0001] This utility model relates to the field of sewing aids technology, and in particular to a sewing aid assembly for the ear loop folding part of a mask. Background Technology

[0002] As people place increasing importance on sun protection, sun-protective masks have evolved from solely providing sun protection to offering a more diversified range that combines style, comfort, and functionality. The market now offers various styles, including ear-loop, tie-on, and headband styles, to meet different wearing needs in various scenarios. As a key component connecting the sun-protective mask to the ears, the design of the ear loops has also been continuously upgraded. In addition to possessing good elasticity, tensile strength, and skin-friendliness, the folded-back design at the end has become an indispensable and crucial element.

[0003] The seemingly small fold at the end of the ear loops plays a crucial role in the product's practicality. Sunscreen masks typically come with adjustment buckles to adjust the ear loop length according to different users' head circumferences or wearing habits, ensuring a tight fit and preventing UV rays from seeping in through gaps. The fold, secured by stitching, forms a sturdy "blocking structure," effectively limiting the adjustment buckle's sliding range on the ear loops and preventing it from detaching. If the fold is defective, the probability of the adjustment buckle detaching increases significantly. This not only causes the mask to lose its length adjustment function, affecting the fit and sun protection, but also may allow the mask to slip off unknowingly due to loose ear loops, rendering it ineffective.

[0004] Furthermore, as consumers increasingly demand higher levels of detail and aesthetic appeal in their products, the craftsmanship of the ear loop folds has become a factor influencing product competitiveness. Neat, straight, and uniformly long folds enhance the overall refinement of the ear loops, creating a harmonious visual effect with the mask itself. Conversely, crooked or unevenly folded ear loops diminish the product's perceived quality, leaving consumers with a rough and unprofessional impression, ultimately impacting brand reputation. Therefore, the processing of the ear loop folds is not only a core element in ensuring the functionality of sun-protective masks but also a crucial consideration for enhancing the product's appearance and market acceptance.

[0005] Currently, the sewing of the ear loops on masks largely relies on manual operation. Workers need to manually fold the ear loops before sewing, which is not only inefficient but also makes it difficult to maintain a consistent fold length and angle, resulting in inconsistent sewing quality and problems such as ear loops falling off and discomfort when wearing the mask. Furthermore, the ear loops are prone to shifting during manual positioning, causing positioning deviations. Utility Model Content

[0006] The purpose of this utility model is to provide a sewing aid assembly for the folded part of the ear loops of a mask. Through the coordinated work of each component, it solves the technical problems of low sewing efficiency and unstable quality of the folded part of the ear loops of masks in the prior art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows:

The winding plate 121 has a flat structure and is made of a thin metal plate with certain toughness and wear resistance, such as stainless steel. Two slots of different lengths are opened at the end of the winding plate 121. The short slot 122 is 1.5-2cm long and the long slot 123 is about 3-5cm long, both with a width of 2-4mm. Forked teeth 124 are formed on both sides of the slots, and the ends of the forked teeth 124 are rounded. The ear loop of the mask is inserted into the slot of the clamp 10 and held by the forked teeth 124 on both sides of the slot. The winding plate 121 is flipped so that the ear loop is wound around it, achieving precise folding of the ear loop.

[0028] The feed tray 20 is mounted on the sewing machine's worktable and includes a rectangular base plate 21. The base plate 21 is the main supporting structure of the feed tray 20 and is a thin metal plate with good strength and stability. Two mounting holes 311 are provided at one end of the base plate 21 for fixing it to the sewing machine's feed mechanism. A positioning frame 23 is provided at the other end for precise positioning. The positioning frame 23 includes a horizontally arranged support platform 231, which is integrally formed and fixedly connected to the base plate 21. The support platform 231 is slightly convex. Its supporting surface is slightly higher than the plane of the substrate 21. A long hole 232 is opened in the center of the front part of the support platform 231. A fixed platform 233 with a certain height is provided at the rear part of the support platform 231. A pair of forward-extending limiting racks 234 are provided on the top of the fixed platform 233 to limit the ear rope after it is folded back and prevent it from deviating during transportation. One end of the limiting rack 234 is fixed to the top of the fixed platform 233, and the other end is a free end. The free end is tilted upward at 15-20°. The distance between the two limiting racks 234 is slightly larger than the width of the long hole 232.

[0029] The presser foot 30 is mounted on the presser foot arm of the sewing machine and includes a mounting part 31 connected to the presser foot arm. The mounting part 31 has mounting holes 311 for fixing the presser foot 30 to the presser foot arm with bolts. An "L"-shaped transmission arm 32 is connected below the mounting part 31. The transmission arm 32 consists of a horizontal section 321 and a downward-sloping section 322. The horizontal section 321 is perpendicularly connected to the mounting part 31, and the downward-sloping section 322 is connected to the horizontal section 321 at a certain angle (120-135°). A presser foot end 33 is connected to the end of the transmission arm 32. The presser foot end 33 includes a presser arm 3... 31 and the pressing table 332, the pressing arm 331 is a downward extension of the lower inclined section 322 of the transmission arm 32, the width of the pressing arm 331 is smaller than that of the transmission arm 32, it connects the lower inclined section 322 and the pressing table 332, and can apply the pressure transmitted by the lower inclined section 322 to the pressing table 332; the end of the pressing arm 331 is provided with a horizontal pressing table 332, the width of the pressing table 332 is adapted to the distance between the two limiting teeth, the lower surface of the pressing table 332 is a horizontal plane, which cooperates with the surface of the support platform 231 of the feeding plate 20, and is used to press the folded ear rope during the sewing process to prevent the material from shifting during sewing.

[0030] In use, the operator first inserts the end of the ear loop into the slot of the working part 12 of the clamp 10, clamps it with the fork 124, and flips the winding plate 121 to fold the ear loop back to the preset length and wrap it around the winding plate 121. After folding, the clamp 10 and the folded ear loop are placed on the positioning frame 23 of the fabric feeding plate 20, so that the limiting rack 234 locks the side of the ear loop. Then, the presser foot 30 moves downward under the action of the sewing machine presser foot arm, the fabric pressing table 332 presses the folded part of the ear loop, and then the clamp 10 is pulled out. The sewing machine is started, and the sewing machine needle sews the folded part through the elongated hole 232. After sewing, the ear loop is removed. The whole process realizes the continuous operation of ear loop folding positioning, feeding and sewing, which effectively improves the accuracy and efficiency of sewing the folded part of the mask ear loop.

[0031] The beneficial effects of this utility model are:

[0032] 1. The innovative design of the clamp 10 in this utility model greatly simplifies the ear cord folding operation. Through the cooperation of the winding plate 121, short groove 122, long groove 123, and fork 124, the operator can quickly and accurately fold the ear cord without complicated manual adjustments, thus improving production efficiency. The good fit between the feed plate 20 and the sewing machine, as well as the stable feeding of the ear cord, reduces downtime for adjustments caused by improper ear cord placement. At the same time, the precise coordination between the presser foot 30 and the sewing machine movement makes the sewing process smoother, further improving production efficiency.

[0033] 2. The clamp 10 of this utility model achieves high standardization and precision in the ear loop folding, ensuring the consistency of the ear loop folding length and angle, and improving quality stability. The positioning frame 23 of the fabric feeding plate 20, through the coordinated action of the support platform 231, the elongated hole 232, the fixing platform 233, and the limiting rack 234, accurately positions the mask ear loops, ensuring the accuracy and stability of the sewing position. The pressing table 332 of the presser foot 30 can evenly press and fix the ear loops, avoiding the formation of wrinkles, making the folded part of the ear loops of the sewn mask flat and firm, greatly improving the overall quality and aesthetics of the mask.

[0034] This invention can be used not only for sewing the folded-back part of the ear loops on masks, but also for sewing the folded-back parts of other garment auxiliary ropes, making the folds straight and uniform in length, improving product production efficiency and quality while also enhancing the product's aesthetics.
