detailed description

The present invention will now be described in further detail with reference to the drawings. These drawings are simplified schematic diagrams, which illustrate the basic structure of the present invention only in a schematic manner, so they only show the constitutions related to the present invention.

This embodiment provides a needle board for a sewing machine with a high-efficiency auxiliary strap edging, as shown in FIG. 1-6, including:

The needle plate main body 1 is provided with a needle passing groove 11 for a sewing needle to pass through;

The outer sleeve 3 is located above the needle plate main body 1 and includes a hollow tube portion 31 on one side and two side plate portions 32 on one side of the hollow tube portion 31. The lower surface of the outer sleeve 3 and the needle plate A third gap 73 between the upper surfaces of the main body 1;

The hollow tube 4 is located in the hollow tube portion 31 of the outer tube 3, and one side of the hollow tube 4 is provided with an integral connecting plate 42. The connecting plate 42 is located between two side plate portions 32 of the outer tube 3. There is a first gap 71 between the outer wall of the hollow tube 4 and the inner wall of the hollow tube portion 31 through the connection block 34 and one of the two side plate portions 32 or both. There is a second gap 72 between the portion 32 and the connecting plate 42, and the first gap 71 communicates with the second gap 72; the interior of the hollow tube 4 is hollow.

When using the needle board of the sewing machine with high-efficiency auxiliary shoulder strap edging in this embodiment, taking FIG. 9 as an example, first pass the elastic band through the third gap 73, and fold the outer cloth (satin) in half (the reverse side of the satin faces outward) ) And through the first gap 71 and the second gap 72, move the elastic band and the outer cloth (satin) to the top shown in Figure 9, the edges of the elastic band and the outer cloth (satin) are aligned, start the sewing machine, and the sewing machine needle is in the Sew the edge of the outer fabric (satin) through the needle slot 11. After stitching a small section, hook a small section into the hollow tube 74 of the hollow tube 4 with tools such as crochet hook 5. At this time, the satin and rubber As the ribs enter the hollow tube 4 from the outside of the hollow tube 4, the front and back sides are reversed, and the rubber band is wrapped inside by the outer cloth (satin), and then the sewing machine is continuously working from the bottom of the hollow tube 4 exit as shown in Figure 9 The stitched elastic band and outer fabric (satin) are drawn continuously, so that the outer fabric (satin) and the elastic band are sewn and the side is completely turned.

The needle plate main body 1 is provided at the bottom of the third gap 73 with a guide groove 12 serving as a guide for passing the elastic band. The guide groove 12 is provided to make the elastic band enter the fourth gap more smoothly, and it is beneficial to align with the edge of the satin (outer cloth) folded in half.

As a specific embodiment, the needle plate main body 1 includes a main body part and a functional part located on one side of the main body part. The needle guide grooves 12 and the guide grooves 12 are provided in the functional part. The main body part is provided with an organic table mounting hole 13 (for screws). (Matching and fixing on the sewing machine), the body part is provided with a mounting seat 2 integrated with the outer sleeve 3 to ensure that the outer sleeve 3 does not directly contact the needle plate main body 1, the lower surface of the outer sleeve 3 and the upper surface of the needle plate main body 1. Forming a third gap 73;

Preferably, as shown in FIGS. 7 to 8, the high-efficiency auxiliary shoulder strap edging sewing machine needle board of this embodiment is provided with a guide frame base 21 on the mounting base 2, and a guide frame is mounted on the guide frame base 21. 6. The guide frame 6 is tilted to one side and has a continuous bent portion 61 for guiding a long outer cloth (satin).

Preferably, as shown in FIG. 2, the needle passing groove 11 has a side opening, so that when the needle plate main body 1 is installed, the sewing needle smoothly enters the needle passing groove 11;

Preferably, as shown in FIG. 1, the length of the hollow tube 4 exceeds the length of the needle groove 11.

Preferably, one end of the crochet needle 5 is a barb and the other end is a ring. To facilitate the use of the crochet 5.

The cross section of the hollow tube 4 may be circular or oval or square.

The method of using the needle board of the sewing machine with the high-efficiency auxiliary shoulder band edging of this embodiment is as follows: step one, passing the elastic band through the third gap 73 to the needle slot 11;

Step 2: Fold the width direction of the satin in half, with the opposite side of the satin facing outward, and passing through the first gap 71 and the second gap 72, and pulling it over the needle groove 11 to overlap with the elastic band;

Step 3: Start the sewing machine. The sewing machine needle sews the edge of the outer cloth (satin) at the needle slot 11. After sewing a small segment, use a crochet hook 5 to hook a small segment of the sewing into the hollow tube of the hollow tube 4. In 74, because the outer cloth (satin) and the elastic band at this time enter the hollow pipe 4 from the outside of the hollow tube 4, the front and back sides are reversed, and the elastic band is wrapped inside by the outer fabric (satin);

Step 4. When tools such as crochet hook 5 pull the stitched outer cloth (satin) and elastic bands from the hollow tube 4 to a sufficient length, remove the tools such as crochet hook 5 and use hand pulls, and then continue working from the figure while the sewing machine is working. At the outlet of the bottom hollow tube 4 shown at 9, the elastic band and outer cloth (satin) that are stitched are pulled out, so that the outer cloth (satin) and the elastic band are stitched and turned over.

Taking the above-mentioned ideal embodiment according to the present invention as a revelation, through the above-mentioned description content, the related staff can make various changes and modifications within the scope of not departing from the technical idea of the present invention. The technical scope of this invention is not limited to the content of the description, and its technical scope must be determined according to the scope of the claims.
