Description

Technical Field

[0001] This utility model relates to the field of sewing clamps, specifically to an automatic sewing machine clamp suitable for shoe toe sewing machines. Background Technology

[0002] Traditional shoe uppers are made using sewing machines, which not only requires two additional steps—printing and gluing—increasing labor costs, but also demands highly skilled operators. Even experienced craftsmen can encounter problems such as uneven stitches, uneven stitch depth, non-rounded curves, and misalignment, resulting in a high rework rate and compromised quality stability. Furthermore, sewing machines are relatively slow, requiring a considerable amount of time to assemble a certain number of shoe uppers, making it difficult to respond quickly to market demands. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical problems and provide an automatic sewing machine clamp suitable for shoe toe sewing machines.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic sewing machine clamp for sewing shoe toe caps, comprising a clamp base, a pressure plate, and a pressing and shaping device. The clamp base is provided with multiple positioning posts for positioning the shoe upper parts to be sewn. One side of the pressure plate is rotatably connected to one side of the clamp base. The pressure plate is provided with a hollow groove, and a pressing block for pressing the shoe upper parts to be sewn is provided in the hollow groove. The pressing and shaping device is disposed at the front end of the pressure plate for pressing against the shoe upper parts to be sewn and forming an arc-shaped curved surface at the front end of the shoe upper parts to be sewn.

[0005] Furthermore, the pressing and shaping device includes a pressing base, a handle, a first connecting rod, a second connecting rod, and a pressing and shaping component. The pressing base is disposed on the pressure plate. The handle and the first connecting rod are rotatably disposed on the pressing base. The two ends of the second connecting rod are rotatably connected to the handle and the first connecting rod, respectively. The pressing and shaping component is disposed on the first connecting rod and is located above the hollowed-out groove.

[0006] Furthermore, the pressing and shaping component includes a connecting part and an arc-shaped plate, the connecting part being disposed on the first connecting rod, and the arc-shaped plate being disposed on the connecting part.

[0007] Furthermore, an adjustment device is provided between the connecting part and the first connecting rod.

[0008] Furthermore, the adjusting device includes a first through hole, an adjusting groove, an adjusting bolt, and a locking nut. The first through hole is disposed on the first connecting rod, the adjusting groove is disposed on the connecting part, the adjusting bolt is disposed in the first through hole and the adjusting groove, and the locking nut is disposed on the adjusting bolt. The locking nut is screwed and connected to the adjusting bolt.

[0011] Furthermore, the fixture base is provided with a machining groove.

[0012] As can be seen from the above description of this utility model, compared with the prior art, the automatic sewing machine clamp for shoe toe sewing provided by this utility model has the following advantages: It is provided with a clamp base and a pressure plate. The clamp base has multiple positioning posts for positioning the shoe upper parts to be sewn, allowing the shoe upper parts to be sewn to be stacked quickly and accurately. One side of the pressure plate is rotatably connected to one side of the clamp base, allowing the pressure plate to quickly press the stacked shoe upper parts together. The pressure plate has a hollow groove through which the shoe upper parts to be sewn can be sewn. A pressing block is provided inside the hollow groove to further press the shoe upper to be sewn. When the components are sewn together, they are sewn along the outer periphery of the pressing block. The pressing and shaping device is set at the front end of the pressure plate to press against the shoe upper component to be sewn above the hollow groove and make the front end of the shoe upper component to be sewn above the hollow groove form an arc surface, so that the arc of the shoe upper after sewing is smooth. Therefore, the shoe upper components to be sewn can be quickly stacked and shaped by the clamp, reducing the two processes of printing lines and spraying glue. Then the clamp is placed on the automatic sewing machine for sewing, which improves the sewing efficiency of the shoe upper and can avoid problems such as uneven stitches, deep or shallow overprinting, uneven arc, and skewing, so as to stabilize the quality of the product and reduce the rework rate.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0019] Reference Figures 1-5 As shown, an automatic sewing machine fixture for sewing shoe toe caps includes a fixture base 1, a pressure plate 2, and a pressing and shaping device 3. The fixture base 1 is provided with multiple positioning posts 11 for positioning the shoe upper components to be sewn. Correspondingly, the shoe upper components to be sewn also have corresponding positioning holes. When the shoe upper components to be sewn are stacked, the positioning posts 11 are inserted into the positioning holes, thereby allowing the shoe upper components to be sewn to be stacked quickly and accurately. One side of the pressure plate 2 is rotatably connected to one side of the fixture base 1, so that the pressure plate 2 can quickly press the stacked shoe upper components to be sewn together. The pressure plate 2 is provided with a hollow groove 21, through which the shoe upper components to be sewn can be sewn. The hollow groove 21 is provided with a device for further pressing the shoe upper components to be sewn. The component has a pressing block 22, and the shape of the pressing block 22 is adapted to the sewing line. During sewing, the sewing is performed along the outer periphery of the pressing block 22.
