Description

Technical Field

[0001] The utility model relates to the technical field of sewing, and particularly relates to a hemming cylinder applicable to a multi-layer composite structure. Background Art

[0002] The renewal of fashion design is extremely fast, which is not only reflected in patterns, fabrics, and design elements, but also in the splicing of fabrics and the selection of clothing decorations. Clothing decorations include decorative strips such as hemming and attachments.

[0003] For fabric splicing, the difficulty mainly lies in different thicknesses and different materials. Especially when one of the fabrics is a lightweight fabric, there are problems such as fabric sliding and wrinkling during the splicing process, resulting in fabric displacement and bulging, and thus an increase in the waste rate. For installing decorative strips, the sewing requirements and difficulties of lace strips under different processes are different. With the development of the clothing industry, many clothes involve the superposition of multiple decorative strips. On the one hand, the splicing of decorative strips made of different fabrics itself is difficult. When multiple decorative strips are superimposed, it also involves a further increase in process requirements. Generally, they need to be installed layer by layer. In addition to low efficiency, the quality is also difficult to control, further increasing the waste rate.

[0004] Both of the above two splicing types have problems such as complex processes, high labor costs, and difficult quality control. And these two splicing types often appear in the same piece of clothing at the same time, which leads to bottlenecks in the entire working sequence when making such clothes, a high probability of significant delays, and low work efficiency.

[0023] The following further describes the utility model in detail with reference to embodiments, but the protection scope of the utility model is not limited thereto.

[0024] The utility model relates to a hemming drawtube applicable to a multi-layer composite structure, which comprises a positioning mechanism 1. At least two reel structures 2 are arranged at the end of the positioning mechanism 1, and adjacent reel structures 2 are cooperatively connected through a partition member 3.

[0025] In the utility model, the whole positioning mechanism 1 is used to position the position to be processed and cooperate with the sewing machine stitches. A plurality of reel structures 2 are arranged at the end of the positioning mechanism 1 to complete the splicing of a plurality of cut pieces and / or decorative strips with different reel structures 2.

[0026] In the utility model, considering that there may be static electricity between a plurality of cut pieces and / or decorative strips, and the feeding of the decorative strips is prone to entanglement, a partition member 3 is arranged between adjacent reel structures 2 to realize the relative isolation of different materials, so that the feeding is smoother and enough adjustment positions are reserved; however, in order to align more than two materials, adjacent reel structures 2 are cooperatively connected, specifically, they are cooperatively connected at the output end for easy adjustment.

[0027] Any one of the reel structures 2 comprises an integrally arranged bottom plate 21. One or more groups of wing pieces 22 are arranged on both sides of the bottom plate 21, and any two wing pieces 22 in a group are detachably connected.

[0029] More than one single-sided buckle 24 is arranged on the other wing piece 22.

[0030] The partition member 3 between adjacent reel structures 2 comprises one or more connecting buckles, and both ends of one or more connecting buckles are respectively connected with the corresponding double-sided buckles 23.

[0031] At least one group of wing pieces 22 is arranged at the end of the bottom plate 21.

[0032] Detachable cushions (not shown in the figure) are respectively arranged on both side surfaces of the bottom plate 21.

[0033] The bottom plate 21 is a flexible metal sheet.

[0034] Different from the structure in the prior art that directly rolls the bottom plate 21 from one side to the other side, one or more groups of wing pieces 22 are respectively arranged on both sides of the bottom plate 21 in the utility model. On the one hand, enough operation space is reserved, including but not limited to folding, hemming, directly serving as a tunnel 4, etc. On the other hand, the processing difficulty is reduced, and the overall thickness is reduced at some positions to ensure the convenience of use when it is used as an auxiliary tool for a variety of materials.

[0035] In the present utility model, the fins 22 appear in groups, and two corresponding fins 22 are detachably connected. The purpose of the detachable connection is mainly to consider coping with different usage scenarios and assisting different materials. Specifically, a double-sided buckle 23 is provided on one fin 22, and a plurality of single-sided buckles 24 are provided on the other fin 22. Different width adjustments of the reel structure 2 can be achieved through the combination of the double-sided buckle 23 and different single-sided buckles 24, including the width of the tunnel 4 when the fins 22 are connected and the overall width of the bottom plate 21 or the fins 22 at the combined part of the bottom plate 21.

Obviously, the connection buckle is also of the double-sided buckle 23 structure. The double-sided buckle 23 here is actually a female buckle structure, and the single-sided buckle 24 is a male buckle structure. At least one of the two buckling ends of the connection buckle is a male buckle structure, and the other is a male buckle structure or a female buckle structure; the above male buckle structure and female buckle structure are both interference fit connections; in fact, in practical applications, considering that the intention of setting the mold is to complete the processing work more quickly, the double-sided buckle 23 and the single-sided buckle 24 can also be set as a magic tape with male and female cooperation, which is easy for those skilled in the art to understand.

[0037] In the present utility model, the separation distance between adjacent reel structures 2 is controllable and adjustable, and is adjusted by combining one or more connection buckles to ensure its application.

[0038] In the present utility model, in order to facilitate the connection of adjacent reel structures 2, at least one group of fins 22 is provided at the end of the bottom plate 21, specifically, at the end of the output end.
