[0023] Reference Figures 1 to 3 The following are several embodiments of the presser foot mechanism and sewing machine of this utility model.

[0024] like Figure 1As shown, the presser foot mechanism of the first aspect of this utility model includes a presser foot body 100 and a guide member 200. The presser foot body 100 is mounted on a sewing machine; the guide member 200 is connected to the presser foot body 100; the guide member 200 is provided with a guide groove 211, which is used to guide the path of the rope.

[0025] The pressure plate body 100 is installed on the sewing machine, and the rope is passed through the guide groove 211. The pressure plate body 100 applies downward pressure to the fabric on the sewing machine table, and the guide groove 211 guides the movement direction of the rope, so that the rope is accurately embedded between the two layers of fabric along a preset path, avoiding the rope from shifting during the embedding process, improving the flatness and consistency of the embedding, and increasing production efficiency. The guide member 200 is connected to the pressure plate body 100, and the relative position of the guide member 200 and the pressure plate body 100 remains unchanged, so that the relative position of the guide member 200 and the sewing machine needle remains unchanged, thereby ensuring the accuracy of the embedding.

[0026] During operation, two layers of fabric are placed on the sewing machine table, and a rope is placed between the two layers. The portion of the rope to be embedded passes through the guide groove 211, allowing the rope to slide within the guide groove 211, thus guiding the movement path of the rope. For example, when sewing a kit, the fabric moves along the sewing machine table for sewing. At this time, the guide member 200 guides the rope to move along the fabric feed direction on the sewing machine table, so that the rope is embedded in the fabric. Here, the fabric feed direction is the direction in which the fabric moves on the sewing machine table.

[0027] This utility model embodiment provides a guide groove 211 in the guide member 200 to guide the movement path of the rope, thereby assisting the rope in embedding into the fabric. This solves problems such as inaccurate rope positioning, loose fit, and low efficiency of manual operation during the rope embedding process, and ensures the quality of sewn products.

[0028] The presser foot 100 applies pressure to the fabric during sewing. This stable pressure prevents the fabric from lifting along with the needle as the needle pierces the fabric, ensuring even stitches, preventing skipped stitches, and preventing fabric slippage. The guide 200 is connected to the presser foot 100. At the start and end of sewing, simply lifting the presser foot 120 raises the guide 200, allowing easy insertion or removal of the beginning or end of the cord or fabric. The guide 200 is fixed to the presser foot 100 without needing to be fixed on the sewing table. During installation, only the position of the presser foot 100 needs to be adjusted; the guide 200 does not require further adjustment, making installation convenient.

[0029] like Figures 1 to 2As shown, in some embodiments, the presser body 100 includes a base 110 and a presser foot 120 mounted on the base 110. The presser foot 120 is provided with a needle drop hole 121. The needle drop hole 121 and the guide groove 211 are arranged along the fabric feeding direction.

[0030] The needle drop hole 121 ensures that the high-speed moving needle can accurately and without error pierce the fabric during sewing without hitting the presser foot 120 itself. The needle drop hole 121 and the guide groove 211 are set along the fabric feeding direction, so that the rope can move along the fabric feeding direction, which facilitates the smooth progress of sewing work. The guide groove 211 helps to realize long-distance, continuous rope embedding operations without having to stop frequently to adjust the rope position.

[0031] like Figures 1 to 2 As shown, in some embodiments, the presser foot 120 is provided with a guide groove 122, which connects to the needle hole 121. The guide groove 122 is used for the rope to pass through, so as to facilitate the rope to the needle hole 121 and thus facilitate the rope burying work. The guide groove 122 and the guide groove 211 extend in the same direction. Through the guide groove 122, the movement path of the rope can be further guided to ensure that the rope does not deviate during the rope burying process.

[0032] like Figures 1 to 2 As shown, in some embodiments, the presser foot body 100 further includes a roller 130, which is rotatably connected to the base 110. Rolling can reduce the resistance between the presser foot mechanism and the fabric. An avoidance groove 131 is provided on the outer periphery of the roller 130. The avoidance groove 131 is used for the rope to pass through, so as to prevent the roller 130 from crushing the rope and affecting the movement of the rope. The avoidance groove 131 is located on the outer periphery of the roller 130. When the roller 130 rolls on the fabric, the rope is embedded in the avoidance groove 131, so as to prevent the rope from hindering the rotation of the roller 130. The avoidance groove 131, the guide channel 122 and the guide channel 211 are correspondingly arranged. The part of the rope to be buried passes through the avoidance groove 131 and the guide channel and then passes through the guide channel 211. The base 110 includes a top plate 111 and two side plates 112, with the top plate 111 connected to the two side plates 112; a roller 130 is rotatably connected to the side plates 112, and an installation space for the roller 130 is formed between the top plate 111 and the side plates 112.

[0033] like Figures 1 to 2 As shown, in some embodiments, the presser foot 120 is provided with a connecting plate 123, which is rotatably connected to the base 110; the guide member 200 is fixed to the connecting plate 123; the presser foot mechanism also includes an elastic member 400, which cooperates with the connecting plate 123 and the base 110, and the elastic member 400 provides an elastic force to the connecting plate 123 so that the presser foot 120 generates downward pressure.

[0034] Understandably, the connecting plate 123 is rotatably connected to the base 110, allowing the presser foot 120 to rotate relative to the base 110. The elastic element 400 provides an elastic force to the connecting plate 123, causing the presser foot 120 to generate downward pressure, thereby enabling the presser foot 120 to press the fabric. The elastic element 400 is connected to the connecting plate 123 and the base 110, limiting the range of motion of the connecting plate 123. The presser foot 120 abuts against the sewing machine table to press the fabric. At this time, the elastic element 400 deforms and applies an elastic force to the connecting plate 123, causing the presser foot 120 to press the fabric. One end of the connecting plate 123 is connected to the presser foot 120, and the other end is connected to the elastic element 400. The middle part of the connecting plate 123 is rotatably connected to the base 110. When the presser foot 120 abuts against the sewing machine table, the elastic element 400 stretches and deforms, generating an upward tensile force on the connecting plate 123. The presser foot 120 and the elastic element 400 are located at opposite ends of the connecting plate 123, and the middle part of the connecting plate 123 is rotatably connected to the base 110, causing the presser foot 120 to press downward. Generally, the elastic element 400 is a spring. The base 110 has connecting plates 123 rotatably connected to both opposite sides. The presser foot mechanism also includes a rear plate, which connects the two connecting plates 123. Correspondingly, two elastic elements 400 are provided, with each elastic element 400 corresponding to one of the connecting plates 123. A hook is provided on the top plate 111, and screws are provided on the connecting plates 123. One end of the elastic element 400 is hung on the hook of the top plate 111, and the other end is fixed to the connecting plate 123 by screws. The guide 200 is fixed to one of the connecting plates 123, and the connecting plates 123 and the presser foot 120 can be fixed by welding.

[0035] like Figures 1 to 2 As shown, in some embodiments, the presser foot mechanism further includes a rotating shaft 300. The guide member 200 and the connecting plate 123 are rotatably connected to the base 110 via the rotating shaft 300, so that the guide member 200 is connected to the base 110, and the guide member 200 and the presser foot member 120 can move synchronously relative to the base 110. In addition, the guide member 200 and the connecting plate 123 are rotatably connected to the base 110 via the rotating shaft 300, which can improve the firmness of the connection between the guide member 200 and the connecting plate 123 and prevent the guide member 200 from detaching.

[0036] like Figure 3 As shown, in some embodiments, the sidewall of the guide groove 211 is provided with a notch 212, which is oriented toward the table of the sewing machine.

[0037] The rope enters the guide groove 211 through the notch 212, making it easy to thread the rope into the guide groove 211. The notch 212 is located on the side of the guide groove 211 facing the sewing machine table, which can prevent the rope from coming out of the guide groove 211 during sewing. The size of the guide groove 211 can be set according to the size of different specifications of ropes, and this embodiment of the utility model does not make any special limitation in this regard.

[0038] like Figure 3 As shown, in some embodiments, the guide member 200 includes a guide rod 220 and a guide block 210. One end of the guide rod 220 is connected to the presser foot member 120, and the other end is connected to the guide block 210. A guide groove 211 is provided on the guide block 210. The guide rod 220 connects the guide block 210 and the presser foot member 120. While serving a connecting function, the guide rod 220 can reduce the volume of the guide member 200, thereby reducing the space occupied by the presser foot mechanism. The guide rod 220 is arranged along the fabric feeding direction and can be connected to the connecting plate 123 of the presser foot member 120. A fixing block is connected to the end of the guide rod 220 away from the guide block 210, and the fixing block can be fixed to the connecting plate 123 by screws.

[0039] like Figure 3 As shown, in some embodiments, the length of the presser foot 120 is less than the length of the guide rod 220 along the fabric feeding direction, so that the guide block 210 at the end of the guide rod 220 can be set outside the presser foot 120, reducing the interference of the presser foot 120 on the guide block 210 and improving the efficiency of burying the rope.

[0040] Compared to manual rope embedding, the presser foot mechanism of this invention can assist in pressing the rope during the embedding process while pressing the fabric, thereby improving the efficiency of rope embedding. The guide groove 211 guides the movement path of the rope, ensuring that the embedding position and depth of the rope are consistent, reducing the defect rate and improving the appearance and quality stability of the sewn products. The structure of this invention is simple, easy to assemble, debug and operate, and can be used by ordinary sewing workers, making it suitable for factory production lines.

[0041] A sewing machine is provided in a second aspect of this utility model, including a presser foot mechanism and a sewing machine body as described in any embodiment of the first aspect.

[0042] It is understood that since the presser foot mechanism has the beneficial effects of the above embodiments, the sewing machine will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0043] The pressure plate body 100 is fixed to the sewing machine. The rope is inserted into the guide groove 211. The sewing machine is turned on, and the upper and lower fabrics are kept flat to perform the rope embedding operation. The guide groove 211 is used to straighten and control the direction of the rope so that the rope can move along the set path during the sewing process.

[0044] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
