Problems solved by technology

[0003] Although the above-mentioned lockstitch sewing machine head can produce a smooth flat seam effect on the material, the sewing thread is prone to breakage during the sewing process. Once the sewing thread falls out of the threading hole of the sewing needle, the operator must remove it. The sewing thread is threaded into the threading hole again, and it is difficult for the operator to thread the threading hole due to the small diameter of the threading hole itself

Embodiment 1

[0042] An intelligent lockstitch machine, see figure 1 as well as figure 2 , including the machine head 1, the machine head 1 is provided with a lifting pressure guide rod 2 and a sewing installation column 4, the end of the lifting pressure guide rod 2 is installed with a lifting presser foot 3, and the sewing installation column 4 is installed with a sewing needle 5. The sewing needle 5 is provided with a threading hole 51 . The lifting and pressing guide rod 2, the sewing installation column 4 and the sewing needle 5 are all vertically arranged.

[0043] see figure 1 as well as figure 2, a protective cover 10 is installed on the lifting and pressing guide rod 2 , and the protective cover 10 surrounds the peripheral position of the lifting and pressing foot 3 .

[0044] see Figure 4 , a rotating member 11 is rotatably connected to the lifting and pressing guide rod 2, the rotation axis of the rotating member 11 is arranged horizontally, and the protective sleeve 10 i...

Embodiment 2

[0060] Embodiment 2: a kind of use method of intelligent lockstitch sewing machine as in Embodiment 1:

[0061] Step 1: Pull down the threading rod 61, the thread hooking end 612 moves down along the sliding groove 8, the threading rod 61 passes through the threading hole 51, and the thread hooking part 7 extends into the outside of the other side of the threading hole 51, The hook-line spring 72 supports the hook-line swing rod 71 upwards and forms the hook-line angle 73, and the threading rod 61 comes out from the limiting hole 411;

[0062] Step 2: According to the actual operation requirements, the threading rod 61 and the lower column 42 are rotated, and the orientation of the hooking part 7 can be adaptively changed. At the same time, the lower column 42 drives the primary transmission gear 121 and the secondary transmission gear 122 in turn. When rotating, the secondary transmission gear 122 drives the driving rack 123 to move downward, the driving rack 123 drives the r...
