Description

Technical Field

[0001] This utility model belongs to the technical field of hem folding devices for sewing machines, specifically referring to a hem folding device for garment hem rolling. Background Technology

[0002] First, many existing hemming machines rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the quality and consistency of the hems due to variations in worker technique. Furthermore, manual hemming can lead to high workloads, worker fatigue, and negatively impact production efficiency and the aesthetics of the final product. Additionally, while some automatic hemming devices can improve efficiency, they may lack necessary adjustment functions, failing to adapt to the hem hemming requirements of different garment styles and sizes. Moreover, when encountering curled fabrics, existing hemming machines cannot automatically flatten the curled portions, requiring manual adjustment by workers, making them inconvenient to use. Utility Model Content

[0003] In order to solve the problems in the prior art, this utility model proposes a fabric hem folding device for garment hems, which can limit the width of the fold when folding the hem of the garment, and automatically flatten the folded edge of the fabric without the need for manual flattening.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a garment hem curling and folding device for garment sewing machines, comprising a mounting plate and a folding device body. The mounting plate is mounted on the garment sewing machine, and the folding device body is mounted on the mounting plate by screws. The folding device body includes a base plate and a rolling section. The edge of the base plate is bent upward to form the rolling section. The end of the rolling section is rolled up to the top of the base plate. There is a gap between the end of the rolling section and the upper surface of the base plate for the fabric to pass through. A cavity is formed in the center of the rolling section. The height of the opening at the end of the rolling section away from the sewing machine presser foot is greater than the height of the opening at the end of the rolling section near the sewing machine presser foot. There is a gap between the roll section and the base plate, allowing the fabric fold to enter the roll section and be blocked by the inner wall of the roll section, thus limiting the fold width without the need for manual adjustment. The opening height of the roll section near the presser foot is relatively low. When the fabric fold passes through, if the edge is curled, the height of the opening near the presser foot is only high enough for a single layer of fabric to pass through due to the gradually decreasing height inside the roll section. The curled-up part of the fabric fold edge is blocked by the rolled edge of the roll section and is unfolded and flattened as the fabric moves forward.

[0005] Furthermore, a hook is fixedly connected to the top of the roll section. The hook faces downwards and is used to support the upper layer of fabric. This prevents the upper layer of fabric from pressing down on the folded edge of the lower layer of fabric, which would cause the fabric to get stuck and difficult to push forward.

[0006] Furthermore, the end of the hook is provided with a spherical portion to prevent sharp edges from scratching the fabric.

[0007] Furthermore, the base plate has a bevel on the side away from the presser foot and near the roll portion. One corner of the base plate with the bevel curves upward along the crease, and the entire roll portion is located on the curved part of the base plate. If the edge of the fabric fold curls downward, when the fabric fold passes over the bevel, the curled part will be blocked by the bevel and unfolded as the fabric advances, keeping the fabric fold flat when it enters below the presser foot. The reason for the bevel to curve upward is to create a gap below the bevel so that the curled part of the fabric can fall down, allowing the fabric above the base plate to adhere to the base plate. As the fabric advances forward, the curled part of the fabric is blocked by the bevel and forced to flatten. If the bevel were made straight, the entire fabric might be lifted, and the curled part of the fabric would also be above the base plate and not be blocked by the bevel.

[0008] Furthermore, the folding device body also includes a guard portion, which is located above the bottom plate near the presser foot of the sewing machine. The guard portion is inclined and forms an acute angle with the roll portion. If there are wrinkles in the fabric fold, or if the edge of the fabric fold curls downward, when the fabric fold passes over the guard portion, the wrinkles or curls will be blocked and flattened by the guard portion, keeping the fabric flat when it enters under the presser foot of the sewing machine. The inclined setting of the guard portion and the acute angle with the roll portion ensure that the force direction when the fabric fold is subjected to force is towards the edge of the fabric fold, making it easier to flatten the fabric fold. When workers manually flatten the curled parts or wrinkles of the fabric, their fingers also apply force in the same direction. If the guard portion is straight, the wrinkles or curls of the fabric may pile up backward and cannot be straightened.

[0009] Furthermore, the mounting plate is provided with a first mounting groove, through which screws pass to mount the mounting plate onto the folding machine. This allows for easy left and right adjustment of the folding body to accommodate different models of folding machines.

[0010] Furthermore, the mounting plate has two threaded holes on the side near the folding machine body, and the base plate has a second mounting groove on the side near the mounting plate. The second mounting groove is perpendicular to the first mounting groove and aligns with the two threaded holes. Screws pass through the second mounting groove and are screwed into the threaded holes. This allows for convenient front-to-back adjustment of the folding machine body to accommodate different models of folding machines.

[0011] Furthermore, the base plate has a notch on the side near the presser foot of the lathe, providing space for the lathe to place a gauge.

[0012] Furthermore, the end of the roll section near the presser foot of the sewing machine is provided with a flattened opening. The flattened opening is formed by grinding off the upper half of the end of the roll section, which reduces the height of the end of the roll section. This allows the hemming device to be placed closer to the presser foot of the sewing machine, so that the fabric is pressed down by the presser foot as soon as it leaves the hemming device, thus preventing the folded fabric from springing back.

[0013] Furthermore, the length of the ground opening is 3mm, and the distance between the end of the rolling section and the end of the flange section is 0.5mm.

[0014] The beneficial effects of this utility model of a fabric hem folding device for garment sewing machines are as follows: It features a roller section with a gap between it and the base plate, allowing the fabric hem to enter and be blocked by the inner wall of the roller section, thus limiting the hem width and eliminating the need for manual adjustment. The opening height of the roller section near the presser foot is relatively low. When the fabric hem passes through, if the edge is curled, the gradually decreasing height inside the roller section means that only a single layer of fabric can pass through the opening near the presser foot. The curled edge of the fabric hem is blocked by the roller section's edge, and is unfolded and flattened as the fabric moves forward. It also includes a hook. This device supports the upper layer of fabric, preventing it from pressing down on the folded edges of the lower layer and causing the fabric to get stuck and difficult to push forward. It features a guard section; if the fabric folded edges are wrinkled or curled downwards, the guard section will stop the wrinkles or curls as the fabric folded edges pass over it, allowing the fabric to remain flat when it enters under the presser foot of the sewing machine. It is flexible in adjustment; the first mounting groove on the mounting plate allows for left-right adjustment of the hemming device body, while the two threaded holes on the mounting plate engage with the second mounting groove on the hemming device body, allowing for front-back adjustment. This improves the adaptability and flexibility of the hemming device, making it suitable for different sewing machine models. Attached Figure Description

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: As Figure 1 As shown, this utility model is a fabric hem folding tool for garment sewing machines, comprising a mounting plate 1 and a folding tool body 2. The mounting plate 1 is mounted on the sewing machine, and the folding tool body 2 is mounted on the mounting plate 1 by screws. The folding tool body 2 includes a base plate 21 and a rolling section 22. The edge of the base plate 21 is bent upward to form the rolling section 22. The end of the rolling section 22 is rolled up above the base plate 21. There is a gap between the end of the rolling section 22 and the upper surface of the base plate 21 for the fabric to pass through. A cavity is formed in the center of the rolling section 22. The opening at the end of the rolling section 22 away from the sewing machine presser foot 3... The height is greater than the height of the opening at the end of the roll section 22 near the presser foot 3. There is a gap between the roll section and the base plate. The fabric fold can enter the roll section and be blocked by the inner wall of the roll section, which can limit the fold width and eliminate the need for manual adjustment of the fold width. The height of the opening at the end of the roll section 22 near the presser foot 3 is lower. When the fabric fold passes through, if the edge is curled, the height of the roll section 22 gradually decreases. Eventually, the height of the opening at the end near the presser foot 3 can only pass through a single layer of fabric. The part of the fabric fold edge that is rolled up is blocked by the rolled edge of the roll section 22 and is unfolded and flattened as the fabric moves forward.

[0021] Furthermore, a hook 24 is fixedly connected to the top of the roll section 22. The hook 24 is oriented and bent downwards. The hook 24 is used to support the upper layer of fabric to prevent the upper layer of fabric from pressing down on the folded edge of the lower layer of fabric, which would cause the fabric to get stuck and difficult to push forward.

[0022] Furthermore, the end of the hook 24 is provided with a spherical portion 241 to prevent sharp edges from scratching the fabric.

[0023] Furthermore, the bottom plate 21 has a bevel 211 on the side away from the presser foot 3 and close to the roll portion 22. One corner of the bottom plate 21 with the bevel 211 is raised upward along the crease 212, and the entire roll portion 22 is located on the raised part of the bottom plate 21. If the edge of the fabric fold curls downwards, as the fabric fold passes over the inclined edge 211, the curled part will be blocked by the inclined edge 211 and unfolded as the fabric advances, keeping the fabric fold flat when it enters below the presser foot 3. The reason why the inclined edge 211 is curved upwards is to create a gap below the inclined edge 211 so that the curled part of the fabric can fall down, allowing the fabric above the base plate 21 to adhere to the base plate 21. As the fabric advances forward, the curled part of the fabric is blocked by the inclined edge 211 and forced to flatten. If the inclined edge 211 is made straight, the entire fabric may be lifted, and the curled part of the fabric will also be above the base plate 21 and cannot be blocked by the inclined edge 211.

[0024] Furthermore, the folding body 2 also includes a guard portion 23, which is located above the bottom plate 21 on the side near the presser foot 3. The guard portion 23 is inclined and forms an acute angle with the roll portion 22. If there are wrinkles in the fabric fold, or if the edge of the fabric fold curls downward, when the fabric fold passes over the guard portion 23, the wrinkled or curled part will be blocked by the guard portion 23 and unfolded and flattened, so that the fabric remains flat when it enters under the presser foot 3. The guard portion 23 is inclined and forms an acute angle with the roll portion 22, so that the force direction when the fabric fold is subjected to force is towards the edge of the fabric fold, making it easier for the fabric fold to be unfolded and flattened. When the worker manually flattens the curled part or wrinkles of the fabric, their fingers also exert force in the same direction. If the guard portion 23 is set straight, the wrinkles or curls of the fabric may pile up backward and cannot be straightened.

[0025] Furthermore, the mounting plate 1 is provided with a first mounting groove 11, and screws pass through the first mounting groove 11 to mount the mounting plate 1 onto the folding machine. This allows for easy left and right adjustment of the folding body 2 to accommodate different models of folding machines.

[0026] Furthermore, the mounting plate 1 has two threaded holes 12 on the side near the folding body 2, and the base plate 21 has a second mounting groove 25 on the side near the mounting plate 1. The second mounting groove 25 is perpendicular to the first mounting groove 11, and the second mounting groove 25 is aligned with the two threaded holes. Screws pass through the second mounting groove 25 and are screwed into the threaded holes. This facilitates the front and rear adjustment of the folding body 2 to adapt to different models of lathes. The portion of the base plate 21 with the second mounting groove 25 is folded upwards, and the bottom surface of the base plate 21 is flush with the bottom surface of the mounting plate 1. The lower surface of the folded portion of the base plate 21 is attached to the upper surface of the mounting plate 1.

[0027] Furthermore, the base plate 21 has a notch 213 on the side near the presser foot 3 of the lathe, which provides space for the lathe to place the gauge 4.

[0028] Example 2: Figure 1 As shown, the difference from Embodiment 1 is that: the end of the roll portion 22 near the presser foot 3 is provided with a flattening opening 221. The flattening opening 221 is formed by grinding away the upper half of the end of the roll portion 22, which reduces the height of the end of the roll portion 22. This allows the hemming device to be placed closer to the presser foot 3, so that the fabric is pressed down by the presser foot 3 as soon as it leaves the hemming device, thus preventing the flattened fabric from springing back.

[0029] Preferably, the length of the ground surface 221 is 3mm. Figure 1 At point A in the middle, the distance between the end of the drum section 22 and the end of the flange section 23 is 0.5 mm. Figure 1 (Point B in the middle).

[0030] The beneficial effects of this utility model of a fabric hem folding device for garment sewing machines are as follows: It features a roller section with a gap between it and the base plate, allowing the fabric hem to enter and be blocked by the inner wall of the roller section, thus limiting the hem width and eliminating the need for manual adjustment. The opening height of the roller section near the presser foot is relatively low. When the fabric hem passes through, if the edge is curled, the gradually decreasing height inside the roller section means that only a single layer of fabric can pass through the opening near the presser foot. The curled edge of the fabric hem is blocked by the roller section's edge, and is unfolded and flattened as the fabric moves forward. It also includes a hook. This device supports the upper layer of fabric, preventing it from pressing down on the folded edges of the lower layer and causing the fabric to get stuck and difficult to push forward. It features a guard section; if the fabric folded edges are wrinkled or curled downwards, the guard section will stop the wrinkles or curls as the fabric folded edges pass over it, allowing the fabric to remain flat when it enters under the presser foot of the sewing machine. It is flexible in adjustment; the first mounting groove on the mounting plate allows for left-right adjustment of the hemming device body, while the two threaded holes on the mounting plate engage with the second mounting groove on the hemming device body, allowing for front-back adjustment. This improves the adaptability and flexibility of the hemming device, making it suitable for different sewing machine models.

The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
