Description

Technical Field

[0001] This application relates to the technical field of textiles, and in particular to a collar corner seam merging and fusion device and a collar corner seam sewing device. Background Technology

[0002] In the textile industry, the traditional process for sewing collar corner seams involves workers using sewing tools or other small tools to sew a single seam along the collar corner. However, this traditional manual operation cannot achieve the required wrinkle-free finish in the corresponding areas, making it difficult to ensure that the finished collar, when turned up normally, has no excess fabric and prevents it from curling up. Furthermore, the traditional manual process for sewing collar corner seams, which simultaneously achieves wrinkle-free finishing, presents difficulties and results in inconsistent and non-standard finished products. Summary of the Invention

[0003] Therefore, in the traditional process of manually sewing collar corners while simultaneously fusing wrinkles, there are difficulties in operation and the finished product results are unstable and non-standard. It is necessary to provide a collar corner sewing and fusing device. The collar corner sewing and fusing device of this invention can reduce the technical difficulty of the collar corner sewing process, simplify operation, improve the finished product effect and standard, and increase production efficiency and stability.

[0007] In some embodiments, the first bottom tooth plate is provided with a plurality of spaced first bottom teeth, and the first toothed pressure block is provided with a plurality of spaced first pressure teeth. When the first bottom tooth plate is pressed onto the first toothed pressure block, the plurality of first bottom teeth and the plurality of first pressure teeth are misaligned and meshed.

[0008] In some embodiments, the spacing between adjacent first bottom teeth is equal, the spacing between adjacent first pressing teeth is equal, the spacing between adjacent first bottom teeth is greater than the width of the first pressing teeth, and the spacing between adjacent first pressing teeth is greater than the width of the first bottom teeth.

[0009] In some embodiments, the second bottom tooth plate is provided with a plurality of spaced second bottom teeth, and the second toothed pressure block is provided with a plurality of spaced second pressure teeth. When the second bottom tooth plate is pressed onto the second toothed pressure block, the plurality of second bottom teeth and the plurality of second pressure teeth are misaligned and meshed.

[0014] In some embodiments, the collar line merging and fusion device further includes an angle plate, one side edge of which is movably connected to the support plate, and there is a gap between the angle plate and the support plate.

[0015] In some embodiments, the sewing channel is arc-shaped to fit the edge of the collar piece, the first bottom tooth plate is arc-shaped near the edge of the sewing channel, the second bottom tooth plate is arc-shaped near the edge of the sewing channel, and the flat bottom plate is arc-shaped near the edge of the sewing channel.

[0016] In some embodiments, the first toothed pressure block is arc-shaped near the edge of the sewing channel, the second toothed pressure block is arc-shaped near the edge of the sewing channel, and the flat pressure block is arc-shaped near the edge of the sewing channel.

[0017] In some embodiments, the position of the first bottom tooth plate and / or the second bottom tooth plate on the support plate is adjustable.

[0018] Another embodiment of the present invention provides a collar corner sewing device.

[0019] A collar seam sewing device includes a sewing mechanism and a collar seam merging and fusion device, wherein the collar seam merging and fusion device is mounted on the sewing mechanism.

[0020] The collar corner stitching and fusion device of the present invention can reduce the technical difficulty of the collar corner stitching process, simplify operation, improve the finished product effect and standard, and improve production efficiency and stability.

[0021] The collar corner seam merging and weaving device of the present invention, in use, places the collar piece on a first toothed plate, a second toothed plate, and a flat bottom plate. At this time, the first toothed pressure block, the second toothed pressure block, and the flat pressure block are all away from the first toothed plate, the second toothed plate, and the flat bottom plate. First, the flat pressure block is controlled to press against the flat bottom plate. At this time, the flat pressure block and the flat bottom plate can press and fix the middle part of the collar piece, realizing the positioning and fixing of the collar piece, and playing the role of preventing the collar piece from moving. Since the angle plate where the first toothed pressure block, the second toothed pressure block, and the flat bottom plate are placed has a certain bending angle, the collar piece will form the same bending angle as the angle plate when it is placed to adapt to this angle. Due to bending and compression, the surface layer of the collar piece... At this point, a certain amount of fabric will be squeezed out, resulting in one side having more fabric and the other side having less fabric, thus creating a taut effect on one side and preventing the finished collar piece from flying up. Next, the first toothed pressing block and the second toothed pressing block are controlled to press against the first bottom toothed plate and the second bottom toothed plate, respectively. Since the teeth on the first toothed pressing block can be misaligned and engaged with the teeth on the first bottom toothed plate, and the teeth on the second toothed pressing block can be misaligned and engaged with the teeth on the second bottom toothed plate, the collar piece pressed between the first toothed pressing block and the first bottom toothed plate, and between the second toothed pressing block and the second bottom toothed plate, will produce a wavy bend, achieving the purpose of wrinkle melting. Then, the sewing mechanism is controlled to sew along the sewing channel to sew the edge of the collar piece, completing the collar corner stitching process. The collar corner seam merging and weaving device of the present invention can achieve single-sided tightening of the collar after the collar corner seam is sewn, uniform wrinkling at both ends, and the wrinkling position is adjustable. When the finished collar is worn and folded normally, the fabric is flat without excess fabric piling up, and the finished collar naturally bends backward without curling up. When using the collar corner seam merging and weaving device of the present invention, you only need to lay the collar, the operation is simple and there is no technical difficulty.
