Description

Technical Field

[0001] The utility model relates to the technical field of garment production technology, in particular to a down jacket cotton collar sewing template. Background Art

[0002] The design and craftsmanship of down jacket collars are crucial to wearing comfort. Currently, down jacket collars are mainly made of two manufacturing processes: down-filled collars and quilted collars. Quilted collars consist of a front collar and an inner collar, with the inner collar close to the neck and the front collar facing outward. However, since the outer fabric of down jackets is mostly made of polyester fiber, its air permeability and moisture conductivity are poor. Wearing it for a long time in winter may make people feel cold in the neck and poor sweat absorption, affecting comfort.

[0003] In order to improve wearing comfort, a pure cotton velvet arc patch is currently added to the middle and lower part of the inner collar of the quilted collar. This design can improve comfort, but the existing production process is relatively cumbersome, requiring a total of seven processes, four flatbed machines and four operators. Especially when sewing irregular arc stitches, due to the large thickness of the front collar and the inner collar, the sewing distance is long and the stitches are prone to skew, and the front collar and the inner collar are prone to asymmetry, all of which increase the difficulty of operation and lead to quality problems.

[0015] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0016] In the first technical solution and related embodiments, a template for sewing a down jacket cotton collar is designed to be divided into two parts, the upper and lower parts. The upper template focuses on the sewing of the face collar, the cutting piece and the arc-shaped patch cutting piece, while the lower template focuses on the sewing of the inner collar and the cutting piece. The combination of these two parts of the template completes the sewing of the face collar and the inner collar. Through the combined use of this template and the automatic template machine, the production process that originally required seven processes, four workers and four flat cars to complete is simplified to a continuous process. This not only greatly reduces the time required for production, but also significantly reduces the production cost and waste of human resources, and significantly improves the production efficiency of the sewing production of down jacket cotton collars.

[0017] In the second technical solution and related embodiments, since the face collar is thick and long, the sewing distance is long and the seams are irregular, in order to avoid the displacement of the collar mouth piece due to the movement of the template or the shaking of the equipment during the sewing process, a second pressing plate is specially added to press the collar mouths at both ends of the face collar, thereby ensuring the stability and accuracy of the sewing process and improving the sewing quality.

[0018] In the third technical solution and related embodiments, considering the relatively large sewing thickness of the cotton collar, in order to improve the accuracy of the placement of the cut pieces, marking lines are used on the upper and lower panels of the template to mark the placement of the cut pieces. By using the upper and lower position marking lines as a common reference, the placement accuracy of the cut pieces is further improved, thereby reducing product quality abnormalities caused by placement errors.

[0019] In the fourth technical solution and related embodiments, masking adhesive is a commonly used tape material and is favored due to its unique characteristics. It has strong adhesion and good bonding force, and can adhere firmly to various materials, making it very suitable for making marking lines.

[0020] In the fifth technical solution and related embodiments, this is one of the embodiments to prevent the pieces from moving. In order to solve the problem of the pieces moving easily due to the large number of pieces and the overall thickness in the process of quilted collar, the following measures are taken: friction areas are set on the inner sides of the upper and lower panels of the template to increase the friction force to avoid the displacement of the pieces due to the movement of the template or the shaking of the equipment during the sewing process. This design ensures the stability and positioning accuracy of the pieces during the sewing process and improves the sewing quality.

[0021] In the sixth technical solution and related embodiments, the friction zone is pasted with coarse sandpaper, which can effectively increase the friction between the template and the cut piece.

[0022] In the seventh technical solution and related embodiments, this is one of the embodiments to prevent the pieces from moving. In order to solve the problem of easy movement of the pieces due to the large number of layers and overall thickness of the pieces in the quilted collar process, hollow grooves are set on the panel and the bottom plate, and magnets are installed in them to avoid displacement of the face collar, inner collar and pieces due to the movement of the template or the shaking of the equipment during the sewing process. This design ensures the stability and positioning accuracy of the pieces during the sewing process, and improves the sewing quality and production efficiency.

[0023] In the eighth technical solution and related embodiments, the snap-on area enables the template to be quickly and conveniently snap-on to the working equipment, ensuring the stability of the connection between the template and the working equipment, reducing the displacement or misalignment of the cutting pieces due to vibration or movement during the sewing process, and improving the stability and precision of the sewing process.

[0024] In the ninth technical solution and related embodiments, the PVC material has good durability and stability, can withstand the friction of multiple uses and repeated positioning, and is not easy to deform or damage. This prolongs the service life of the template and reduces the cost increase caused by frequent template replacement. At the same time, the PVC material has good waterproof properties, can resist the penetration of water and other liquids, keep the template dry and clean, and ensure that the accuracy of positioning is not affected by moisture or pollution. In addition, the PVC material can be recycled and reused, meeting the requirements of environmental sustainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The first sewing groove 32 is used to determine the sewing path. Specifically, the first sewing groove 32 is two long arc-shaped traces, which are arranged along the upper and lower edges of the first marking line 31.

[0043] The first pressing plate 34 is located outside the middle position of the lower end of the first marking line 31 and is detachably connected to the first bottom plate 3 so that the first pressing plate 34 can rotate in the direction close to the first marking line 31 and cover the middle part of the first marking line 31 to press the arc-shaped cut piece; in this embodiment, the first pressing plate 34 and the first bottom plate 3 are connected by a side guard strip.

[0044] There are two second pressing plates 35, and the two second pressing plates 35 are respectively close to the outer sides of the two ends of the first marking line 31 and are detachably connected to the first bottom plate 3 so that the two second pressing plates 35 can rotate in the direction close to the first marking line 31 and cover the two ends of the first marking line 31 to press the collar mouth and the cutting piece. Since the face collar is thick and long, the sewing distance is long and the stitches are irregularly curved, in order to avoid displacement of the collar mouth and the cutting piece due to the movement of the template or the shaking of the equipment during the sewing process, a second pressing plate 35 is specially added to press the collar mouths at both ends of the face collar, which ensures the stability and accuracy of the sewing process and improves the sewing quality. In this embodiment, the second pressing plate 35 is connected to the first bottom plate 3 by a side guard strip.

In addition, PVC material can be recycled and reused, which meets the requirements of environmental sustainability.

[0061] In this embodiment, a second marking line 41 is set on the surface of the first panel 4 facing the first bottom plate 3, and a fourth marking line 61 is set on the surface of the second panel 6 facing the second bottom plate 5. Considering the large sewing thickness of the cotton collar, in order to improve the accuracy of the placement of the pieces, marking lines are used on the upper and lower panels of the template to mark the placement of the pieces. By using the upper and lower position marking lines as a common reference, the placement accuracy of the pieces is further improved, thereby reducing the abnormal product quality caused by placement errors.

[0062] In this embodiment, the second marking line 41 and the fourth marking line 61 are both marked with masking adhesive. Masking adhesive is a commonly used tape material and is favored due to its unique characteristics. It has strong adhesion and good bonding force, can be firmly adhered to various materials, and is very suitable for making marking lines.

[0063] In this embodiment, a template for sewing a cotton collar of a down jacket is designed to be divided into two parts, an upper part and an lower part. The upper template 1 is focused on sewing the face collar, the cutting piece and the arc-shaped patch cutting piece, while the lower template 2 is focused on sewing the inner collar and the cutting piece. The combination of these two parts of the template completes the sewing of the face collar and the inner collar. Through the combined use of this template and the automatic template machine, the production process that originally required seven processes, four workers and four flat cars to complete is simplified to a continuous process. This not only greatly reduces the time required for production, but also significantly reduces the waste of production costs and human resources, and significantly improves the production efficiency of sewing cotton collars for down jackets.
