[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In the present invention, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to the specific circumstances.

[0039] In addition, terms such as "first" and "second" are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "plurality" is two or more.

[0040] Next, the technical solutions provided by the present invention will be further described in conjunction with the embodiments and the accompanying drawings.

[0041] In traditional clothing enterprises, stitching mainly relies on manual sewing by workers. Due to the increasing diversification of clothing styles, short delivery cycles, and high quality requirements, skilled workers are needed for manual stitching. However, there are currently few skilled workers, and the training cycle for new employees is long, resulting in problems such as high labor intensity of workers, high production costs, and difficulty in ensuring product quality.

[0042] Among them, for the splicing process between different fabrics, one fabric needs to be folded, and another fabric is stitched to this fabric. However, when folding the fabric, the staff needs to first fold the raw edge of the fabric by hand and then iron it to set the shape. This manual operation method has poor stability, resulting in uneven widths of the raw edge and the crease, and is not conducive to stitching with another fabric, and there may be problems with poor sewing tightness.

[0043] Based on the above problems, the embodiment of the present application provides a presser foot device, which is used for the stitching process of different fabrics, makes the distance between the raw edge and the crease uniform, has a good splicing effect between different fabrics, and helps to improve the production and processing efficiency.

[0044] The embodiment of the present application provides a presser foot device, as Figures 1 to 2 shown, the presser foot device includes:

[0045] A guiding controller 1, the guiding controller 1 includes a first fabric passing structure 11 and a second fabric passing structure 12 connected to each other. The first fabric passing structure 11 is used to fold the first fabric 3 to form a main fabric 31 and a hem fabric 32. The second fabric passing structure 12 is arranged on the side close to the hem fabric 32. The second fabric passing structure 12 is used to pass the second fabric 4. The projection of the second fabric passing structure 12 in the horizontal direction on the first fabric passing structure 11 has an overlapping area, and the entrance direction of the second fabric passing structure 12 is opposite to the entrance direction of the first fabric passing structure 11;

[0046] A presser foot 2, the presser foot 2 is movably connected to the guiding controller 1. The presser foot 2 is used to press the main fabric 31, the hem fabric 32, and the second fabric 4. A needle passing hole 21 is formed through the thickness direction of the main fabric 31, the hem fabric 32, and the second fabric 4 on the presser foot 2. The needle passing hole 21 is used to stitch the main fabric 31, the hem fabric 32, and the second fabric 4 located in the overlapping area.

[0047] The presser foot device provided by this application includes a guiding controller 1 and a presser foot 2. Among them, the guiding controller 1 includes a first fabric passing structure 11 and a second fabric passing structure 12. Under the action of the first fabric passing structure 11, the first fabric 3 is folded to form a main fabric 31 and a hemmed fabric 32, which improves the folding efficiency and ensures a relatively high uniformity of the distance between the raw edge of the first fabric 3 and the crease. And because the second fabric passing structure 12 is arranged on the side close to the hemmed fabric 32 and the entrance direction of the second fabric passing structure 12 is opposite to the entrance direction of the first fabric passing structure 11, it is ensured that the raw edges of the first fabric 3 and the second fabric 4 are in the same direction, improving the aesthetics after sewing.

[0048] Moreover, since the presser foot 2 is provided with a needle passing hole 21 penetrating through the thickness directions of the main fabric 31, the hemmed fabric 32 and the second fabric 4, and the main fabric 31, the hemmed fabric 32 and the second fabric 4 have an overlapping area, the fabrics acted on by the guiding controller 1 will, under the pressing action of the presser foot 2, ensure the relative positions of the main fabric 31, the hemmed fabric 32 and the second fabric 4 in this overlapping area. Therefore, when sewing with a sewing needle in cooperation with the needle passing hole 21, the fabrics will not shift, enabling the first fabric 3 and the second fabric 4 to be effectively sewn together, ensuring the sewing effect and improving the aesthetics of the sewn garment.

[0049] In addition, this application uses the guiding controller 1 to fold the first fabric 3, ensure the relative positions of the first fabric 3 and the second fabric 4, and under the pressing action of the presser foot 2, achieve a shaping effect, making their relative positions not shift. This not only reduces the errors caused by manual folding but also omits the ironing and shaping process, optimizing the processing steps and thus helping to improve the production and processing efficiency.

[0050] Furthermore, the materials of the first fabric passing structure 11 and the second fabric passing structure 12 in this application are both metal materials. The surface of this material is smooth and has less resistance, facilitating the passing of the fabric. The metal materials include materials such as aluminum alloy and ferroalloy. And different folding channels can be set in the first fabric passing structure 11, so as to achieve various types of hemming.

[0051] Further, as Figure 3 shown, the first fabric passing structure 11 includes a top plate 111 and a first bottom plate 112 arranged oppositely, and side plates 113 respectively connecting the two ends of the top plate 111 and the first bottom plate 112. The top plate 111, the first bottom plate 112 and the side plates 113 enclose a first C-shaped channel 11a;

[0052] The first fabric passing structure 11 further includes a partition plate 114. The partition plate 114 is arranged between the top plate 111 and the first bottom plate 112, and there is a gap between the partition plate 114 and the side plate 113. The partition plate 114 is used to divide the first C-shaped channel 11a into a first channel 111a and a second channel 112a that communicate with each other. The second channel is located on the side close to the second fabric passing structure 12, and the second channel is used to pass the hemmed fabric 32. The first channel is located on the side away from the second fabric passing structure 12, and the first channel is used to pass the main fabric 31;

[0053] The first fabric passing structure 11 further includes a first baffle 115. Two ends of the first baffle 115 are respectively connected to the first bottom plate 112 and the partition plate 114.

[0054] Therefore, when the first fabric 3 is placed into the first channel 111a and pushed inward until it reaches the side plate 113, under the blocking action of the side plate 113, a part of the first fabric 3 will bend and then enter the second channel 112a to form the hemmed fabric 32. The bending method of the present application not only avoids the problem that the folding effects of fabrics in different batches are quite different during manual folding, but also helps to improve the processing efficiency, and makes the distance between the frayed edge and the crease of the first fabric 3 uniform, ensuring the sewing effect after final splicing.

[0055] Further, referring back to Figure 3 , the second fabric passing structure 12 includes: a second bottom plate 121, which is arranged opposite to the first bottom plate 112; a second baffle 122, with two ends of the second baffle 122 respectively connected to the first bottom plate 112 and the second bottom plate 121; the second bottom plate 121, the second baffle 122 and the first bottom plate 112 enclose a second C-shaped channel 11b, and the second C-shaped channel 11b has an opening direction opposite to that of the first channel 111a.

[0056] Moreover, in order to align the frayed edges of the first fabric 3 and the second fabric 4, the positions of the first baffle 115 and the second baffle 122 are aligned, and the first baffle 115 and the second baffle 122 are used in cooperation to align the frayed edge of the hemmed fabric 32 and the frayed edge of the second fabric 4.

[0057] The setting method of the first baffle 115 and the second baffle 122 in the present application aligns the frayed edges of the hemmed fabric 32 and the second fabric 4, so that the fabric obtained after sewing has a better sewing effect and the appearance of the clothing is more beautiful. In addition, compared with the manual alignment method, it not only helps to improve the alignment accuracy, but also helps to improve the production and processing efficiency.

[0058] In addition, in order to increase the stability of the connection between the first fabric passing structure 11 and the second fabric passing structure 12, the various plate-like structures can be connected together through a welding process, thereby ensuring the stability of the connection between the various plate-like structures of the first fabric passing structure 11 and the second fabric passing structure 12, which helps to increase their service life.

[0059] In an optional embodiment, the side panel 113 is a flat structure. In another optional embodiment, the side panel 113 is an arc structure, and the side panel 113 is bent in a direction away from the first baffle 115. Compared with the flat structure, when the first fabric 3 is pushed to the side panel 113 area, the first fabric 3 is bent and folded along the arc structure, which reduces the difficulty of folding the first fabric 3 and facilitates the folding of the fabric.

[0060] In an optional embodiment, if Figure 4 As shown, the partition 114 includes an isolating portion 1141 and an extending portion 1142 which are connected to each other. The position of the isolating portion 1141 corresponds to the position of the top plate 111 , and the extending portion 1142 is located on the side away from the presser foot 2 , and is used to support the first cloth 3 . If the width of the first fabric 3 is greater than the width of the isolation portion 1141, the first fabric 3 outside the isolation portion 1141 will be affected by gravity, thereby hindering the inward pushing process of the first fabric 3, and the existence of the extension portion 1142 has a relatively good supporting effect on the first fabric 3 outside the isolation portion 1141, so that the first fabric 3 in the inner and outer areas is evenly stressed, which not only helps to reduce the difficulty of bending the first fabric 3, but also makes the first fabric 3 located at the extension portion 1142 present a bent state, thereby reducing the difficulty of subsequent entry into the first fabric passing structure 11; in another optional embodiment, the first bottom plate 112 includes an isolation section and an extension section connected to each other, the extension section is located on the side away from the presser foot 2, and the position of the isolation section corresponds to the position of the top plate 111, so the extension section can better support the folded edge fabric 32, and the folded edge fabric 32 located in the extension section will not have a tendency to sag due to the influence of gravity, reducing the difficulty of its entry into the first fabric passing structure 11, which helps to improve the processing efficiency.

[0061] For further information, see Figure 2 The guide controller 1 further includes a fixing structure 13, the fixing structure 13 is used to connect the first cloth to the presser foot 2 through the structure 12, and the fixing structure 13 and the presser foot 2 are connected along a first direction (see Figure 2is movably connected in the X direction (in the figure) so that the distance between the first fabric and the presser foot 2 in the first direction can be changed relative to the structure 11, where the first direction is the inlet direction of the first fabric passing through the structure 11. Therefore, by adjusting the position of the first fabric passing through the structure 11 relative to the presser foot 2, the relative positions of the raw edges of the hemmed fabric 32 and the second fabric 4 and the sewing machine needle are changed, so that the distance between the sewing thread and the crease can be adjusted, thereby achieving different appearance effects.

[0062] In an alternative embodiment, the fixing structure 13 includes a fixing plate 131 and a threaded connector 132. The fixing plate 131 is provided with a fixing groove extending in the first direction, and the presser foot 2 is provided with a fixing hole. The threaded connector 132 is arranged through the fixing hole along the fixing groove, and the fixing plate 131 and the presser foot 2 are movably connected through the threaded connector 132; in another alternative embodiment, the fixing plate 131 is provided with a plurality of holes, and the threaded connector 132 passes through the fixing hole on the presser foot 2 along the holes, thereby realizing the movable connection between the fixing plate 131 and the presser foot 2. Compared with the solution of providing a plurality of holes on the fixing plate 131, the structure of providing a fixing groove on the fixing plate 131 makes the distance between the sewing thread and the crease more diverse, with more adjustment possibilities and more diverse appearance effects that can be achieved. And the connection method using the threaded connector 132 is simple to adjust, which helps to improve the production and processing efficiency, and the processing cost of the threaded connector 132 is relatively low, which is beneficial to reducing the replacement and maintenance costs.

[0063] Further, referring back to Figure 2 , the presser foot 2 includes: a fixing member 22 for connecting with a garment processing device; a pressing plate 23 connected to the fixing member 22, and the fixing member 22 is located above the pressing plate 23. The pressing plate 23 is movably connected to the guiding controller 1, and the pressing plate 23 is provided with a needle-passing hole 21. The presser foot 2 is fixed on the garment processing device through the fixing member 22, and since the presser foot 2 is connected to the guiding controller 1, the guiding controller 1 can cooperate with the garment processing device, so that the fabric affected by the guiding controller 1 can be directly transmitted under the pressing plate 23. At the same time, the pressing plate 23 applies an external force to the fabric, so as to ensure that the fabric coming out of the first fabric passing structure 11 and the second fabric passing structure 12 will be pressed by the pressing plate 23 and continue to maintain its original shape, making the effect of the sewn fabric better.

[0064] Among them, the garment processing device includes a sewing machine. When the presser foot 2 is installed on the sewing machine, the sewing needle on the sewing machine is used to pass through the needle-passing hole 21 to sew the fabric, so that the splicing process of two different fabrics is completed under the cooperation of the sewing machine and the presser foot device.

[0065] Moreover, since the fixing member 22 is installed on the garment processing equipment, in order to ensure that the position of the fixing member 22 does not shift during the processing and to ensure the sewing effect. Thus, along the processing direction of the first fabric 3 and the second fabric 4 (see Figure 2 the Y direction in

[0066] ), two limiting plates 24 are connected to both sides of the pressing plate 23. The fixing member 22 is connected to the two limiting plates 24 and is located between the two limiting plates 24. The two limiting plates 24 are used to limit the position of the fixing member 22 on the pressing plate 23. Among them, the processing direction is perpendicular to the entry direction of the first fabric through the structure 11.

[0067] Furthermore, in order to reduce the difficulty for the fabric to reach under the pressing plate 23, improve the production efficiency, and ensure the sewing effect. As Figure 5 shown, the pressing plate 23 includes a horizontal section 231 and an inclined section 232 which are connected to each other. A needle-passing hole 21 is provided on the horizontal section 231. The inclined section 232 is arranged close to one side of the needle-passing hole 21 and is inclined upward. The inclined section 232 is movably connected to the guiding controller 1; the guiding controller further includes an inclined plate 14. The inclined plate 14 is used to connect the fixing structure 13 and the first fabric through structure 11. The inclined plate 14 is inclined downward. The inclined plate 14 cooperates with the inclined section 232 so that the first fabric 3 passing through the first fabric through structure 11 and the second fabric 4 passing through the second fabric through structure 12 are both located under the pressing plate 23.

[0068] This application adopts the structure of the cooperation between the inclined section 232 and the inclined plate 14, so that the heights of the first fabric through structure 11 and the second fabric through structure 12 are both higher than that of the pressing plate 23. Therefore, the fabrics acted on by the first fabric through structure 11 and the second fabric through structure 12 will reach the bottom of the pressing plate 23 faster under the action of gravity, which helps to improve the production efficiency.

[0069] In addition, referring back to Figure 4In order to ensure the stability of the connection between the first cloth passing structure 11 and the pressing plate 23, and to ensure that the first cloth passing structure 11 can be applied to pressing plates 23 of different widths. The guide controller 1 also includes a connecting plate 15, which is connected to the surface of the top plate 111 on one side away from the partition plate 114, and the length of the connecting plate 15, the inclined plate 14 and the fixed plate 131 in the first direction is equal to the width of the pressing plate 23 in the first direction, so that not only the stability of the connection between the first cloth passing structure 11 and the pressing plate 23 is ensured, but also the first cloth passing structure 11 can be connected to pressing plates 23 of different widths by using connecting plates 15, inclined plates 14 and fixed plates 131 of different lengths.
