The end of the adjusting knob 6 is fixedly connected to the second gear 18. The outside of the adjusting screw 8 is provided with a screw sleeve 9. The bottom end of the screw sleeve 9 is fixedly connected to an adjusting rod 10. The bottom end of the adjusting rod 10 is fixedly connected to a mounting base 13. The bottom end of the mounting base 13 is detachably installed with a pressure foot body 11. The side of the connecting seat 5 is provided with a limit post 17. The two sides inside the support frame 7 are fixedly connected to limit slides 14.

[0023] A sensor transmitter is provided at the top of the lead screw sleeve 9, a position sensor 15 is provided above the lead screw sleeve 9, a self-locking structure is provided on the adjustment knob 6, the second gear 18 movably passes through the support frame 7 and is fixedly connected to the adjustment knob 6, and the first gear 16 is meshed with the second gear 18.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the height of the presser foot body 11 can be adjusted according to the thickness of the fabric. When adjusting, first open the self-locking structure on the adjustment knob 6, then rotate the adjustment knob 6. The second gear 18 on the adjustment knob 6 meshes with the first gear 16 and rotates. The adjustment screw 8 rotates synchronously, which can drive the presser foot body 11 to move. When moving, the position sensor 15 can accurately detect the adjusted position.

[0025] The bottom end of the adjusting rod 10 slides through the bottom end of the support frame 7. The two sides of the screw sleeve 9 are slidably connected to the outside of the limiting slide 14.

The bottom end of the presser foot body 11 is fixedly connected with a rubber pad 12.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, a rubber pad 12 is installed at the bottom of the presser foot body 11. When the presser foot body 11 repeatedly presses the fabric, the rubber pad 12 can reduce the noise generated by the presser foot body 11. During the up and down movement of the presser foot body 11, the limiting post 17 can limit its linear movement and reduce the noise between the connecting rods.

[0027] The top of the presser foot body 11 is fixedly connected to the mounting block 20, and the front end of the mounting base 13 is provided with the mounting bolt 19. The mounting block 20 is embedded in the interior of the mounting base 13 and fixed by the mounting bolt 19.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the presser foot body 11 is fixedly mounted on the mounting base 13 by mounting bolts 19. During the use of the embroidery machine, the presser foot body 11 can be replaced as needed. When replacing, first unscrew the mounting bolts 19 on the mounting base 13, and then remove the mounting block 20 on the presser foot body 11 from inside the mounting base 13.

[0029] Working principle: In use, the drive motor 1 drives the drive shaft 2 to rotate. The drive shaft 2, through the first connecting rod 3 and the second connecting rod 4, drives the presser foot body 11 to move up and down. The height of the presser foot body 11 can be adjusted according to the thickness of the fabric. To adjust, first open the self-locking mechanism on the adjustment knob 6, then rotate the adjustment knob 6. The second gear 18 on the adjustment knob 6 meshes with the first gear 16 and rotates. The adjusting screw 8 rotates synchronously, thus driving the presser foot body 11 to move. During movement, the position sensor 15 can accurately detect the adjusted position. The presser foot body 11 is fixedly installed by the mounting bolts 19. On the mounting base 13, during the use of the embroidery machine, the presser foot body 11 can be replaced as needed. When replacing, first unscrew the mounting bolts 19 on the mounting base 13, and then remove the mounting block 20 on the presser foot body 11 from inside the mounting base 13. A rubber pad 12 is installed at the bottom of the presser foot body 11. When the presser foot body 11 repeatedly presses the fabric, the rubber pad 12 can reduce the noise generated by the presser foot body 11. During the up and down movement of the presser foot body 11, the limiting post 17 can limit its linear movement and reduce the noise between the connecting rods. This structure realizes the functions of easy low noise and stable limiting.
