The limiting ring piece 51 and the spring 50 are both sleeved on one end of the stabilizing rod 49 away from the lower stabilizing block 48. The tightening block 52 is threadedly connected to the stabilizing rod 49 away from the lower stabilizing block 48. At one end away from the lower stabilizing block 48, the two ends of the spring 50 are respectively pressed against the limiting ring piece 51 and the tightening block 52, the limiting ring piece 51 is pressed against the upper stabilizing block 47, the upper mop shaft 58 passes through the upper stabilizing block 47 and is rotatably connected to the upper stabilizing block 47, the upper and lower mop shafts 37 pass through the lower stabilizing block 48 and are rotatably connected to the lower stabilizing block 48, during the rotation of the upper mop shaft 58, the upper mop shaft 58 will shake slightly, and the spring 50 will deform slightly. Since the force is mutual, the spring 50 will apply a force to the upper stabilizing block 47 to reduce the amplitude of the shaking of the upper stabilizing block 47.
[0067] The implementation principle of Example 1 is: when sewing lace, two needles are installed on the sewing machine 6 according to needs, the bottom edge fabric roll is pre-covered on the fabric release rod, the first bent edge fabric roll is covered on the first fold edge fabric release rod 12, the second bent edge fabric roll is covered on the second fold edge fabric release rod 13, and the two lace ropes are covered on the rope release rod 11.
[0068] The bottom edge fabric roll, the first bent edge fabric roll, the second bent edge fabric roll and the two lace rope rolls are unwound so that the bottom edge fabric first passes through the tensioning rod 9 and then passes through the gap between the cloth pressing piece 18 and the bottom film 17, and then the bottom edge fabric is pulled out from the gap between the cloth pressing piece 18 and the bottom film 17.
[0069] Then pass the first bent edge fabric through the first folding device 19, the first bent edge fabric is folded in half, a lace rope on a lace rope roll is passed through the first folding device 19 through the rope guide tube 27, and the lace rope is placed in the folded first bent edge fabric, the lace rope is close to the bending part of the first bent edge fabric, and the first bent edge fabric with the lace rope is passed through the first retaining member.
[0070] Pass the second bent edge fabric through the second folding device 20, the second bent edge fabric is folded in half, the lace rope on another lace rope roll is passed through the second folding device 20 through the rope guide tube 27, and the lace rope is placed in the folded second bent edge fabric, the lace rope is close to the bending part of the second bent edge fabric, and the second bent edge fabric with the lace rope is passed through the second retaining member.
[0071] At this time, the relative positions of the first bent edge, the second bent edge, the bottom edge and the lace rope have been formed, and only sewing by the sewing machine 6 is required. There is no need to manually place the positions of the first bent edge, the second bent edge, the bottom edge and the lace rope, and the lace sewing efficiency is high.
[0072] When the sewing machine 6 is working, the sewing machine 6 sews the first bent edge and the bottom edge together, sews the second bent edge and the bottom edge together, passes the sewn lace through the upper mop shaft 58 and the lower mop shaft 37, so that the two sides of the lace respectively contact the anti-slip sleeve 41, and the rotating shaft of the sewing machine 6 drives the input shaft of the reducer 36 to rotate through the transmission mechanism, and then drives the lower mop shaft 37 to rotate through the cooperation of the first gear 45 and the second gear 46, and the lower mop shaft 37 drives the upper mop shaft 58 to rotate synchronously in the opposite direction through the cooperation of the upper gear 38 and the lower gear 39, so that the sewn lace is automatically dragged forward.

[0074] Reference Fig.13 The difference between this embodiment and embodiment 1 is that a motor 53 is provided on the sewing table 5, and the motor 53 is linked with the upper mop shaft 58 or the lower mop shaft 37. In this embodiment, the motor 53 is linked with the lower mop shaft 37, and the output shaft of the motor 53 is connected to the input shaft of the reducer 36.
[0075] The implementation principle of the second embodiment is as follows: the motor 53 provides a power source in the working state, thereby driving the input shaft of the reducer 36 to rotate, thereby realizing the rotation of the upper mop shaft 58 and the lower mop shaft 37 .
[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
