Description

Technical Field

[0001] This utility model relates to the field of fabric hemming technology, specifically a fabric hemming tool. Background Technology

[0002] A sewing machine is a mechanical device used to sew fabrics. It uses the up-and-down movement of the needle to pass the thread through the fabric, forming stitches and thus connecting the fabrics together. It can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. It is fast and easy to use.

[0003] Existing sewing machines require the fabric to be placed under the sewing needle before sewing. However, the fabric placement is usually done manually by pushing it while pulling it with the other hand to sew the two pieces together. This manual operation is tiring and dangerous, as it increases the risk of the operator being pricked by the sewing needle. Therefore, a fabric hemming device is proposed to solve these problems. Summary of the Invention

This device allows fabric to be placed under the sewing machine needle for convenient sewing, and the sewing process is simple and quick. It solves the problem that existing sewing machines require the fabric to be placed under the needle before sewing, which often involves manual pushing and pulling of the fabric with one hand to sew it together. However, this manual pulling is tiring and poses a safety risk of needle pricks during sewing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the embodiments, by Figure 1-5 The present invention provides a fabric hemming tool, comprising a mounting base plate 1 and a connecting shell 2. The connecting shell 2 is welded to the top of the mounting base plate 1. A mounting shell 3 is fixedly connected to the top of the connecting shell 2. A pushing shell 4 is welded inside the mounting shell 3. A pushing hole 5 is provided on the outer wall of the pushing shell 4, extending through and to the outside of the pushing shell 4. A U-shaped limiting rod 7 is detachably connected to the outside of the pushing shell 4 via a snap-fit ​​assembly 6. The snap-fit ​​assembly 6 is used to adjust the height position of the U-shaped limiting rod 7.

[0027] The mounting base plate 1 has a mounting hole 8 at its top, and a number of mounting bolts 9 are provided inside the mounting hole 8. The mounting bolts 9 pass through the mounting hole 8 and are threadedly connected to the external equipment.

[0028] The mounting base plate 1 is placed on the outside of the sewing machine, and a threaded hole is provided on the outside of the sewing machine. Then, the mounting hole 8 and the threaded hole are aligned, and the mounting bolt 9 is installed into the inside of the mounting hole 8. This restricts the position of the mounting base plate 1 to the outside of the sewing machine, which facilitates the subsequent use of the entire device.

[0029] The mounting hole 8, together with the mounting bolt 9, allows for easy installation of the mounting base plate 1, preventing changes in its position during use.

[0030] The outer surfaces of the U-shaped limiting rod 7 and the connecting shell 2 are both polished, and the U-shaped limiting rod 7 is located on the right side of the pushing shell 4.

[0031] The outer surfaces of the U-shaped limiting rod 7 and the connecting shell 2 are both polished, which facilitates the pushing of the fabric and makes the pushing of the fabric strip more efficient.

[0032] The snap-fit ​​assembly 6 includes a snap-fit ​​box 61 fixed to the outside of the push shell 4 and a snap-fit ​​plate 62 fixed to the outside of the U-shaped limiting rod 7. A rotating threaded rod 63 is rotatably connected to the inside of the snap-fit ​​box 61, and a rotating sleeve 64 is provided at the bottom of the snap-fit ​​plate 62. The inside of the rotating sleeve 64 is threadedly engaged with the outside of the rotating threaded rod 63.

[0033] When it is necessary to disassemble the U-shaped limiting rod 7, the rotating threaded rod 63 can be rotated to move the rotating sleeve 64 up and down under the action of the thread, thereby changing the height of the U-shaped limiting rod 7 at the top of the rotating sleeve 64, increasing the overall flexibility of the device. At the same time, when the rotating sleeve 64 is completely separated from the rotating threaded rod 63, the U-shaped limiting rod 7 can be taken out from the outside of the push shell 4 for easy storage.

[0034] The rotating threaded rod 63 is connected to a rotating sleeve 10 at its bottom. The outer wall of the rotating sleeve 10 is provided with anti-slip texture. The cross-sectional shape of the inner cavity of the snap-fit ​​box 61 is adapted to the shape of the outer wall of the rotating sleeve 64, and the two form a sliding pair.

[0035] The rotating sleeve 10 allows for easy rotation of the threaded rod 63, and the outer wall of the rotating sleeve 10 is provided with anti-slip texture, which can enhance the performance of the rotating sleeve 10.

[0036] Working principle:

[0037] After mounting the base plate 1 on the outside of the sewing machine by mounting bolt 9, and with the connecting shell located in front of the sewing machine needle, the fabric to be sewn is then placed crosswise into the inside of the U-shaped limiting rod 7. After passing through the pushing hole 5 on the outside of the pushing shell 4, the fabric moves from the pushing hole 5 to below the sewing machine needle, and then the sewing operation is performed.

[0038] The fabric can be shaped by pushing the hole 5, so that the two edges of the fabric to be sewn are evenly fed into the sewing machine needle through the pushing hole 5 for sewing. At the same time, the U-shaped limiting rod 7 can stretch the fabric, improving the overall sewing effect.
