Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a fabric cutting structure of a sewing machine. Background Art

[0002] In the garment manufacturing industry, a sewing machine is a commonly used device for splicing the edges of two pieces of fabric together. The key part of this machine is its fabric cutting structure, which is responsible for precisely cutting the fabric edges to facilitate splicing and sewing.

[0003] Some existing fabric cutting structures of sewing machines usually include a fixed blade, which cuts the fabric when it passes through. The fabric moves passively to adapt to the cutting position of the blade. The structure is simple but stable.

[0004] However, for relatively thick or hard fabrics, a single fixed blade may not provide enough pressure to ensure stable cutting. Secondly, these fabric cutting structures are often fixedly arranged and cannot adjust the angle according to the characteristics of different fabrics, resulting in poor adaptability. Summary of the Utility Model

[0005] In view of this, the utility model provides a fabric cutting structure of a sewing machine, which can provide stable and effective cutting and improve the adaptability to fabrics of different materials.

[0006] To solve the above technical problems, the utility model provides a fabric cutting structure of a sewing machine, including a mounting plate. A support plate is fixedly connected to the middle of one side of the mounting plate. Two blades are rotatably connected to the center of the top of the support plate. The middle parts of the two blades are rotatably connected to the same rotating shaft, and the rotating shaft is arranged at the center of the top of the support plate. A screw rod is threadedly connected to the other side of the mounting plate. A connecting ring is threadedly connected to the middle of the screw rod. Connecting seats are fixedly connected to both sides of the connecting ring. A connecting rod is rotatably connected between each connecting seat and the adjacent blade. An avoidance opening is formed in the middle of the mounting plate, and the blades are both located in the middle of the avoidance opening, which can provide more stable and effective cutting and realize flexible adjustment of the blade position, so as to adapt to fabrics of different materials.

[0007] One end of the screw rod is fixedly connected with a rotating block, and a plurality of grooves are arranged around the rotating block in the middle of the rotating block; that is, fine adjustment of the screw rod is realized by rotating the rotating block.

[0008] A limiting block is threadedly connected to the end of the screw rod close to the mounting plate, and the limiting block is attached to the mounting plate; that is, it prevents the screw rod from moving excessively due to repeated use.

[0009] A connecting plate is fixedly connected to the top of the mounting plate; that is, it provides the docking position of this device with the sewing machine.

[0010] Two symmetrically arranged mounting openings are provided in the middle of the connecting plate; this facilitates connection to other devices.

[0011] A converging opening is provided in the middle of the support plate, and the inner diameter of the converging opening is smaller than the opening diameter of the converging opening; this helps to keep the fabric stable during the shearing process.

[0012] A pressing opening is provided at the bottom of the mounting plate, and both ends of the pressing opening are higher than the middle; this helps to keep the position of the fabric after shearing.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The two blades help prevent the fabric from sliding or shifting during shearing, and the converging opening helps guide the material into the shearing area, keeping the fabric stable during the shearing process, and can provide more stable and efficient cutting.

[0015] 2. When the connecting seat approaches the blade, the connecting rod is squeezed, and then the end of the blade close to the connecting seat is pushed to move to both sides. Conversely, when the connecting seat moves away from the blade, the connecting rod drives the blade to move closer to the middle. This adjustment mechanism enables the blade to rotate around the rotating shaft, and then adjusts the end of the blade for cutting the fabric, realizing flexible adjustment of the blade position, so as to adapt to fabrics of different materials and achieve efficient shearing.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] like Figures 1-4 As shown: the present embodiment provides a shearing structure of a stitching machine, comprising a mounting plate 100, a connecting plate 110 is fixedly connected to the top of the mounting plate 100, two symmetrically arranged mounting openings 111 are provided in the middle of the connecting plate 110, a support plate 101 is fixedly connected to the middle of one side of the mounting plate 100, two blades 102 are rotatably connected to the top center of the support plate 101, the middle parts of the two blades 102 are rotatably connected to the same rotating shaft, the rotating shaft is arranged at the top center of the support plate 101, the cutting edges of the two blades 102 are both facing the middle part of the support plate 101, the two blades 102 are staggered up and down, an avoidance opening 107 is provided in the middle part of the mounting plate 100, the blades 102 are all located in the middle part of the avoidance opening 107, a gathering opening 112 is provided in the middle part of the support plate 101, the inner diameter of the gathering opening 112 is smaller than the opening diameter of the gathering opening 112, a pressing opening 113 is provided at the bottom of the mounting plate 100, and both ends of the pressing opening 113 are higher than the middle part;

[0024] The installation opening 111 facilitates the connection between the device and the stitching machine. The two blades 102 work together to enhance the cutting effect. The avoidance opening 107 allows the blade 102 to change its angle within a certain range, thereby improving the adaptability of the shearing structure to different fabrics. The gathering opening 112 helps guide the material into the shearing area, so that the fabric is continuously aggregated under the guidance, which is convenient for cutting. The pressing opening 113 helps to apply pressure to the fabric after shearing is completed, thereby preventing the fabric from leaving the processing range.

[0025] Screw 103 Figure 1 , 4 As shown,

[0026] A screw rod 103 is threadedly connected to the other side of the mounting plate 100, a connecting ring 104 is threadedly connected to the middle of the screw rod 103, a connecting seat 105 is fixedly connected to both sides of the connecting ring 104, a connecting rod 106 is rotatably connected between the connecting seat 105 and the adjacent blade 102, one end of the screw rod 103 is fixedly connected to a rotating block 108, a plurality of grooves arranged in an array around the rotating block 108 are provided in the middle of the rotating block 108, one end of the screw rod 103 close to the mounting plate 100 is threadedly connected to a limiting block 109, and the limiting block 109 is fitted with the mounting plate 100;

[0027] The rotating block 108 enables the user to conveniently rotate the screw rod 103 for fine adjustment. The rotation of the screw rod 103 causes the connecting ring 104 to generate an axial displacement along the screw rod 103 under the limitation of the connecting rod 106. The connecting ring 104 is transmitted between the blade 102 through the connecting seat 105 and the connecting rod 106. When the connecting seat 105 approaches the blade 102, the connecting rod 106 is squeezed, and then the blade 102 is pushed to move both sides near the end of the connecting seat 105. On the contrary, when the connecting seat 105 moves away from the blade 102, the connecting rod 106 drives the blade 102 to move closer to the middle. This adjustment mechanism enables the blade 102 to rotate around the rotating shaft, and then adjusts one end of the blade 102 for cutting the fabric, realizing the flexible adjustment of the position of the blade 102, so as to adapt to fabrics of different materials and achieve efficient cutting. The limiting block 109 limits the moving range of the screw rod 103 to prevent the movement of the screw rod 103 caused by repeated use.

[0028] Working principle:

[0029] The rotation of the screw rod drives the connecting ring to displace axially along the screw rod. The connecting ring is connected to the blade through the connecting seat and the connecting rod. When the connecting seat approaches the blade, the connecting rod is squeezed and pushes the blade to move both sides; when the connecting seat moves away from the blade, the connecting rod drives the blade to move closer to the middle. The two blades cooperate with each other to improve the cutting efficiency and improve the adaptability to different fabrics by adjusting the blade angle.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
