Description

Technical Field

[0001] The utility model relates to the technical field of sewing moulds, in particular to a double-layer module device suitable for decorative strips on sewing machines. Background Art

[0002] The double-layer decorative strip backpack strap is a classic design of backpack strap. The double-layer structure can provide better tensile strength and comfort. The decorative stripes on the surface increase the friction between the strap and the shoulder and back to prevent the backpack from falling off. The sewing of the double-layer decorative strip is not complicated. It only requires two decorative strips to be stacked together. However, traditional sewing is more dependent on the level of the sewing master. The edges of the decorative strips are easy to fall off during sewing, resulting in uneven edges and inconsistent sizes of the edges, which greatly affects the sewing work efficiency.

[0003] To this end, the utility model provides a decorative strip double-layer module device suitable for a sewing machine to solve the above-mentioned problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a double-layer module device for decorative strips on a sewing machine, so that when a sewing master sews decorative strips, the edges of the decorative strips are of consistent size and will not fall off, so that sewing novices can also sew, thereby improving sewing work efficiency.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a double-layer module device suitable for decorative strips on sewing machines, including a fixed connecting block, a nut connecting hole is opened on the fixed connecting block, and a double-layer mold is fixedly installed on the top of the fixed connecting block.

[0006] Preferably, the double-layer mold comprises an upper mold and a lower mold, and the upper mold is smaller than the lower mold.

[0007] Preferably, the upper mold is located at the middle of the top of the lower mold and is fixedly connected by welding.

[0008] Preferably, the nut connection holes are provided with three groups in total, wherein two groups of the nut connection holes are distributed on both sides of the fixed connection block, and the third group of the nut connection holes is located in the middle of the fixed connection block.

[0009] Preferably, each group of nut connecting holes are waist-shaped holes.

[0010] Preferably, upper stoppers are fixedly mounted on both sides of the top of the upper mold, and guide plates are fixedly mounted on the front bottom ends of the upper mold and the lower mold.

[0011] Beneficial Effects

[0012] The utility model provides a double-layer module device for decorative strips on sewing machines. Compared with the prior art, it has the following beneficial effects:

[0013] When using the device, the sewing master can fix the fixed connecting plate on the sewing machine through the set nut connecting holes, and then two groups of decorative strips of different sizes pass through the set upper mold and the lower mold respectively. When the decorative strips pass through the upper mold, the setting of the upper stopper in the device allows the decorative strips passing through the upper mold to move more stably, so that when the sewing master sews the decorative strips, the edge dimensions of the decorative strips can achieve a consistent effect and will not fall off, so that sewing novices can also sew double-layer decorative strips well, thereby improving the work efficiency of sewing double-layer decorative strips, and also improving the quality of the finished products of sewing double-layer decorative strips. In addition, by setting each group of nut connecting holes as waist-shaped holes, the staff can adjust the position when fixing the device to prevent deviations in the installation position, which will affect the sewing process.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] See also Figure 1-4A double-layer module device for decorative strips on a sewing machine includes a fixed connecting block 1, a nut connecting hole 2 is opened on the fixed connecting block 1, a double-layer mold 3 is fixedly installed on the top of the fixed connecting block 1, and the double-layer mold 3 includes an upper mold 301 and a lower mold 302. The upper mold 301 is smaller than the lower mold 302. The upper mold 301 is located in the middle position of the top of the lower mold 302 and is fixedly connected by welding.
