The first driving module includes a linear slide rail 11 and a second driving cylinder 12. One side of the linear slide rail 11 is slidably connected with a slide block 2. The second driving cylinder 12 can be adjusted through a computer control system to control the front-back movement and translation travel parameters of the mounting base 1 (i.e., the upper folding shovel module 3 and the lower folding shovel module 4 as a whole). The sewing machine main body is provided with a computer control system, and the computer control system is electrically connected to the first driving module, the upper folding shovel module 3, the lower folding shovel module 4 and the lifting assembly 5.
[0023] The mounting base 1 is slidably connected to the first driving module in the front and rear directions through a slider 2. The upper folding shovel module 3 is fixedly connected to the upper surface of the mounting base 1. The lower folding shovel module 4 is slidably connected to the mounting base 1 in the up and down directions through a first lifting cylinder 7. Both the upper folding shovel module 3 and the lower folding shovel module 4 include a plurality of folding knives 6 and a second driving module fixedly connected to the folding knives 6. The second driving module includes a bottom plate 8 and a first driving cylinder 9. The bottom plate 8 is of a U-shaped structure. The folding knives 6 are respectively arranged at both ends, the midpoint, and the bending position of the bottom plate 8, with a total of five folding knives 6. The driving shaft of the first driving cylinder 9 faces the inner circle of the bottom plate 8, and the folding knives 6 are fixedly connected to the driving shaft of the first driving cylinder 9. The traveling parameters of the folding knives 6 can be controlled by adjusting the first driving cylinder 9 through a computer control system.
[0024] Specifically, a first connecting plate 10 is provided at the middle position of the upper surface of the mounting base 1. The middle position of the upper folding shovel module 3 is fixedly connected to the first connecting plate 10. The first lifting cylinders 7 are symmetrically arranged on the side walls of the mounting base 1 with the first connecting plate 10 as the center. The driving shafts of the first lifting cylinders 7 are located on both sides of the upper folding shovel module 3 and are fixedly connected to the edge of the upper surface of the lower folding shovel module 4. The lifting of the lower folding shovel module 4 can be controlled by adjusting the first lifting cylinders 7 through a computer control system. Cooperating with the stationary upper folding shovel module 3, it is convenient to press the fabric when folding the edge.
[0025] The lifting assembly 5 includes a second connecting plate 13, a second lifting cylinder 14, a third connecting plate 15, and a third lifting cylinder 16.

The driving shaft of the third lifting cylinder 16 is fixedly connected to the middle position of the bottom of the second connecting plate 13. The other side of the third connecting plate 15 is fixedly connected to the sewing machine main body. The up and down lifting of the whole (i.e., the mounting base 1 and the first driving module) and the traveling parameters of the lifting can be controlled by adjusting the second lifting cylinder 14 and the third lifting cylinder 16 through a computer control system, and two-stage lifting is achieved.
[0026] During the actual use process, the fabric to be processed is placed at the lower left position of the linear slide rail 11. The mounting base 1 moves from the right side to the left side of the linear slide rail 11. Subsequently, the second lifting cylinder 14 and the third lifting cylinder 16 control the whole mounting base 1 to move down to the specified position, so that the fabric to be processed is between the upper folding shovel module 3 and the lower folding shovel module 4. The first driving cylinder 9 drives the folding knives 6 to move towards the inner circle of the bottom plate 8, so that the edge of the fabric is folded inwards. At the same time, the first lifting cylinder 7 drives the folding knives 6 to move upwards to press the fabric, and the folding edge process can be completed. Then, it can enter the sewing process under the control of the sewing machine main body.
