Description

Technical Field

[0001] The utility model relates to the technical field of folding mechanisms, in particular to a folding mechanism of an automatic sewing machine. Background Art

[0002] In the textile and garment industries, automatic sewing machines are crucial production equipment, and their efficiency and sewing quality directly impact product production efficiency and quality. However, during the sewing process, fabric often needs to be folded to complete specific sewing tasks, such as cuffs and collars. Therefore, a folding mechanism is required to perform this specific folding operation.

[0003] Traditional automatic sewing machines often rely on manual operation when folding fabrics. The operation is complicated and the adjustment is inflexible. This not only increases labor intensity, but also makes it difficult to ensure the accuracy and consistency of folding, affecting the sewing quality. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the folding mechanism relies on manual operation, is complicated to operate and is inflexible to adjust, which not only increases the labor intensity but also makes it difficult to ensure the accuracy and consistency of folding, thus affecting the sewing quality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A folding mechanism for an automatic sewing machine comprises a fixed plate provided on a sewing machine body, an N-shaped limit block being slidably connected to the upper surface of the fixed plate, a fixed block being fixedly connected to one side of the limit block, and a folding plate being rotatably connected to one side of the fixed block;

[0007] The upper surface of the fixed block is fixedly connected to a fixing frame, the interior of the fixing frame is rotatably connected to a threaded block, the inner thread of the threaded block is connected to a screw, one end of the screw is rotatably connected to a rotating sleeve, the rotating sleeve is rotatably connected to the upper surface of the folding plate, and the screw is used to adjust the folding angle of the folding plate.

[0008] In one possible design, two groups of fixing holes are provided on the upper surface of the sewing machine body, the fixing plate is arranged in an L shape, and two fixing wires are installed on the upper surface of the fixing plate. Both of the fixing wires are threadedly connected to one group of fixing holes to control the folding direction of the fabric.

[0009] In a possible design, a second rack is fixedly connected to the bottom of the limit block, a first rack is fixedly connected to one side of the fixed plate, and the first rack is meshed with the second rack.

[0010] In a possible design, a groove is provided on one side of the fixing plate, a movable rod is slidably connected to one side of the limiting block, and one end of the movable rod is fixedly connected to a cam.

[0011] In a possible design, one end of the screw rod is fixedly connected to a handle.

[0012] In a possible design, a placement groove is provided inside the folding plate, and the placement groove is used for placing cloth.

[0013] In a possible design, the length of the first rack is greater than that of the second rack.

[0014] In a possible design, one end of the movable rod is fixedly connected to a handle.

[0015] In this application, when the fabric needs to be folded, the direction of the fabric folding is determined by first selecting a fixing wire and connecting it to one of the sets of fixing holes. Then, the limit block is placed in the appropriate position and the cam is pushed into the groove. The engagement of the first rack and the second rack effectively limits the displacement of the limit block.

[0016] By rotating the movable rod, the cam is relatively fixed in the groove, which facilitates the fixation of the folding plate. Then, one side of the fabric is placed in the placement groove of the folding plate, and the screw is rotated to fold the folding plate around the fixed block through thread adjustment.

[0017] During the folding process, the stability and safety of the folding process are ensured. Finally, when the fabric is folded to the desired angle, the screw is stopped and the position of the folding plate is fixed to complete the fabric folding operation, and the sewing machine is used for the next operation.

[0018] Beneficial effects:

[0019] In the utility model, the folding mechanism of the automatic sewing machine realizes automatic folding of the fabric by setting the folding plate, reduces manual operation and improves work efficiency. At the same time, since the folding angle can be accurately adjusted, the time for repeated folding and adjustment is reduced, further improving production efficiency.

[0020] In the utility model, the folding mechanism of the automatic sewing machine can control the direction of fabric folding by adjusting the connection between the fixing wire and different groups of fixing holes, which enables the folding mechanism to adapt to the needs of different sewing tasks and has strong adaptability and flexibility.

[0028] Reference Figures 1-4 A folding mechanism includes: a fixing plate 3 provided on a sewing machine body 1, the fixing plate 3 being mounted in one of a set of fixing holes 4 on the sewing machine body 1 via fixing wires 5, ensuring that the L-shaped structure of the fixing plate 3 is in close contact with the upper surface of the sewing machine body 1, and being fixed by threading the fixing wires 5 into the fixing holes 4. One of the sets of fixing holes 4 can be selected for fixing according to the folding direction of the fabric 2;

[0029] Next, the n-shaped limit block 13 is slidably connected to the upper surface of the fixed plate 3 to ensure that the limit block 13 can slide along the fixed plate 3. The fixed block 14 is fixedly connected to one side of the limit block 13. Then, the folding plate 6 is rotatably connected to the fixed block 14 so that the folding plate 6 can be folded around the fixed block 14.

[0030] In order to control the folding angle of the folding plate 6, a fixing frame 10 is fixedly connected to the upper surface of the fixing block 14, and a threaded block 11 is rotatably connected inside the fixing frame 10. The threaded block 11 is internally threaded and connected to the screw 8. One end of the screw 8 is rotatably connected to the rotating sleeve 9. The rotating sleeve 9 is rotatably connected to the upper surface of the folding plate 6. By rotating the screw 8, the folding angle of the folding plate 6 relative to the fixing block 14 can be controlled to achieve precise folding of the fabric 2.

[0031] In order to further enhance the stability and adjustment flexibility of the folding mechanism, the second rack 15 is fixedly connected to the bottom of the limit block 13, and the first rack 12 is fixedly connected to one side of the fixed plate 3, so that the first rack 12 and the second rack 15 are engaged. The position of the limit block 13 on the fixed plate 3 can also be adjusted to facilitate limiting the distance between the folding plate 6 and the sewing machine needle.

One end of the movable rod 18 is fixedly connected to a cam 17. By pushing the cam 17 so that it is located in the groove 16, the movable rod 18 is rotated to drive the cam 17 to rotate in the groove 16, so that the limit block 13 is firmly fixed on the fixed plate 3. In order to facilitate operation, a handle is fixedly connected to the other end of the movable rod 18 so that the operator can operate it easily.

[0036] In order to facilitate the adjustment of the screw 8, a handle is fixedly connected to one end of the screw 8, so that the operator can easily rotate the screw 8 to control the folding angle of the folding plate 6. At the same time, a placement groove 7 is provided inside the folding plate 6 for placing the cloth 2 to ensure that the cloth 2 can remain stable during the folding process.
