Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, and in particular to a device for fixing stitching for cloth shoe soles. Background Technology

[0002] Cloth shoes have a long history of over 3,000 years in my country. The most time-consuming and laborious process in making cloth shoes is sewing the soles. First, an awl is used to pierce the soles, which are made of thirty or forty layers of cloth glued together. Then, a needle with thread is passed through the soles. This process is repeated. It takes at least several hundred stitches to sew a single sole. It is evident that a fixed sewing device for sewing the soles of cotton cloth shoes can bring many conveniences to the production of cloth shoes.

[0003] In existing technologies, the stitching of shoe soles is usually done by sewing machine. During the sewing process, the direction of the stitching needs to be manually adjusted, which is cumbersome and poses certain safety hazards. Utility Model Content

[0021] Example 1

[0022] like Figures 1-4 As shown in the figure, the present embodiment proposes a fixed sewing device for attaching soles to cloth shoes, which includes a frame 1, a transmission belt 3, a small sewing machine 15, a power mechanism, and a pressing mechanism.

[0023] An opening 101 is provided on the frame 1; a base plate 11 is provided on the inner side of the opening 101, and there is a gap between the base plate 11 and the opening 101. The purpose of this arrangement is to allow the small sewing machine 15 to move the sewing thread.

[0024] A transmission belt 3 is arranged around the outside of the opening 101. Several vertical ribs are provided on the transmission belt 3 to prevent deformation in the middle of the transmission belt 3. Multiple limiting roller assemblies are arranged at equal intervals along the circumference on both the inner and outer sides of the transmission belt 3. The limiting roller assembly includes two transmission rollers 4 arranged side by side with a gap between them. A mounting frame 2 is provided above the transmission belt 3. A fixing frame 10 is connected between the mounting frame 2 and the frame 1. The two transmission rollers 4 arranged side by side are rotatably mounted on the mounting frame 2 and the frame 1, respectively.

[0025] A sewing machine mounting base 14 is connected to the inner surface of the transmission belt 3, and a small sewing machine 15 is mounted on the sewing machine mounting base 14.

[0026] The power mechanism is mounted on the frame 1 to drive the transmission belt 3. The power mechanism includes two symmetrically arranged traction components. The traction components include a servo motor 7, a take-up reel 8, and a traction rope 9. The servo motor 7 is mounted on the frame 1, and the take-up reel 8 is mounted on the output shaft of the servo motor 7. One end of the traction rope 9 is fixedly wound on the take-up reel 8, and the other end is wound around the outer surface of the transmission belt 3 and connected to the transmission belt 3. The winding directions of the two traction ropes 9 on the two sets of traction components are opposite.

[0027] The clamping mechanism is installed above the frame 1. The clamping mechanism includes a first electric push rod 6 and a pressure plate 5. A gantry frame 13 is provided on the frame 1. The first electric push rod 6 is installed on the gantry frame 13. The pressure plate 5 is connected to the output shaft of the first electric push rod 6. When the first electric push rod 6 is started, it drives the pressure plate 5 to move down, so that the pressure plate 5 is pressed against the sole of the shoe, thereby effectively fixing the sole of the shoe and preventing the sole from shifting.

[0028] Specifically, when fixing the stitches on the sole, the sole is placed on the base plate 11. It should be noted that the transmission belt 3 is similar to the sole, and the edge of the sole extends beyond the edge of the base plate 11. A small sewing machine 15 is used to sew the sole. During this process, one side of the servo motor 7 is activated to wind up the transmission belt 3. The winding disc 8 can pull the transmission belt 3 during the winding process. It should be noted that at this time, the other side of the servo motor 7 needs to be activated to release the thread, so that the small sewing machine 15 moves around the path of the transmission belt 3, thereby realizing the sewing of the sole. The whole process does not require manual movement and changing of the stitch direction of the sole, which saves time and effort and improves the safety of operation.

[0029] Example 2

[0030] like Figure 3As shown in the figure, the fixed sewing device for making the sole of cloth shoes proposed in this embodiment, compared with the first embodiment, has the following features: one side of the base plate 11 is rotatably mounted on the bottom end of the frame 1, and the bottom end of the frame 1 is equipped with a second electric push rod 12 for driving the base plate 11 to rotate. It should be noted that the second electric push rod 12 is rotatably mounted on the bottom end of the frame 1, and its output shaft is rotatably connected to the base plate 11. After the second electric push rod 12 drives the base plate 11 to flip downward, the sewn sole on the base plate 11 slides off the inclined surface, realizing the function of automatic unloading and further improving work efficiency.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
