A first cylinder 10 is installed on the first support frame 9, and a first template positioning block 11 is fixedly installed at the telescopic end of the first cylinder 10; the other end of the lower surface of the double-layer slide 4 is slidably connected to a second support frame 12 through a slider, and a second cylinder 13 is installed on the second support frame 12. A second template positioning block 14 is fixedly installed at the telescopic end of the second cylinder 13, and the first template positioning block 11 and the second template positioning block 14 are respectively movably connected to the left and right sides of the first sewing template 5 and the second sewing template 6;

[0028] Pulley mounting frames 15 are installed at both ends of the double-layer slide 7, and pulleys are installed in the pulley mounting frames 15. A traction belt 16 is wound around the two pulleys. The traction belt 16 is arranged around the outside of the double-layer slide 7. The lifting slide module 8 and the second support frame 12 are both connected to the traction belt 16; one of the pulleys is connected to the traction drive unit to drive the pulley to rotate.

[0029] Working principle:

[0030] When in use, first place the first sewing template 5 and the second sewing template 6 side by side on the front and rear sides of the upper surface of the table 4; then lay the cloth to be sewn on the first sewing template 5 and fix it; in the initial state, the lifting slide module 8 is located at the rear end of the double-layer slide 7, and the second support frame 12 is located at the front end of the double-layer slide 7; then start the equipment, at this time, the telescopic end of the first cylinder 10 drives the first template positioning block 11 to extend, so that the first template positioning block 11 is respectively connected to the left and right sides of the second sewing template 6, and then the lifting slide module 8 is controlled to drive the entire first support frame 9 and the second sewing template 6 to move upward and rise; at the same time, the telescopic end of the second cylinder 13 also drives the second template positioning block 14 to extend, so that the second template positioning block 14 is respectively connected to the left and right sides of the first sewing template 5.

[0031] Afterwards, the traction drive unit is controlled to drive the pulley to rotate, and then drive the traction belt 16 to move around the outer surface of the double-layer slide 7. Since the lifting slide module 8 and the second support frame 12 are both connected to the traction belt 16, the movement of the traction belt 16 can drive the lifting slide module 8 to move toward the front end along the double-layer slide 7, while the second support frame 12 moves toward the rear end along the double-layer slide 7; thereby, the first sewing template 5 with the cloth laid on it moves to the rear of the table 4 and corresponds to the sewing machine head assembly 3, while the second sewing template 6 without the cloth laid on it reaches the front of the table 4.

[0032] At this time, the lifting slide module 8 is controlled to drive the first support frame 9 to move downward, and then the second sewing template 6 is lowered to the position on the upper surface of the table 4, and then the telescopic end of the first cylinder 10 is controlled to retract, so that the second sewing template 6 is separated from the first support frame 9, and the staff again lays the cloth to be sewn on the second sewing template 6 for fixation; at the same time, the cloth on the first sewing template 5 is sewn through the sewing machine head assembly 3. During this process, the traction drive unit can be continued to be controlled to drive the pulley to perform servo rotation, and then the second support frame 12 can be driven to move forward and backward in the Y-axis direction along the axial direction of the double-layer slide 7. At the same time, the X-axis walking mechanism is controlled to drive the entire sewing machine head assembly 3 to move left and right along the X-axis direction, and then the sewing of the entire surface of the cloth on the first sewing template 5 is realized.

[0033] After the fabric on the first sewing template 5 is sewn, the telescopic end of the second cylinder 13 is controlled to retract, so that the second template positioning block 14 is separated from the first sewing template 5, and the traction drive unit is controlled to drive the pulley to rotate, so that the lifting slide module 8 and the second support frame 12 return to the initial position again, and the above steps are repeated, so that the first sewing template 5 and the second sewing template 6 can be alternately and uninterruptedly sewing. Then the work efficiency is greatly improved.

When the X-axis travel mechanism is used to drive the sewing machine head assembly 3 to move left and right along the X-axis direction, the servo motor 23 is controlled to operate, and then the spur gear can be driven to rotate, so that the entire sliding support plate 22 is driven to move axially along the X-axis guide rail 21 through the meshing effect of the spur gear and the rack 24, and then the sewing machine head assembly 3 is driven to move left and right along the X-axis direction.

Since the two ends of the transmission shaft 32 are connected to the central axes of the two pulleys, the two pulleys are driven to rotate synchronously.

[0038] Embodiment 5, as a further preferred solution of embodiment 1, a first positioning cylinder 42 is installed on the front side of the table 4, and a second positioning cylinder 43 is installed on the lower surface of the rear half of the table 4.

Therefore, when the first template positioning block 11 or the second template positioning block 14 is controlled to extend, the first template positioning block 11 and the second template positioning block 14 and the fixed hanging plates 51 can be used to limit and fix the first sewing template 5 and the second sewing template 6 to the first template positioning block 11 and the second template positioning block 14, so as to ensure that the first sewing template 5 and the second sewing template 6 can be stably fixed with the first template positioning block 11 and the second template positioning block 14. Then the stability of the first sewing template 5 and the second sewing template 6 when moving is ensured.
