detecting whether the looper moves leftward in a case where the needle moves upward;
in the case where the needle moves downward, it is detected whether the looper moves rightward.
4. The control method according to claim 2, wherein the sewing machine further comprises an upper shaft, a lower shaft, an upper shaft driving structure and a lower shaft driving structure, wherein the needle is connected with the upper shaft, the looper is connected with the lower shaft, the upper shaft driving structure is used for driving the upper shaft to move, and the lower shaft driving structure is used for driving the lower shaft to move.
5. The control method according to claim 4, wherein before simultaneously controlling the needle and the looper movement, the control method comprises:
locking the upper shaft drive structure and the lower shaft drive structure such that the upper shaft drive structure and the lower shaft drive structure move simultaneously.
6. The control method according to claim 5, wherein in a case where the needle and the looper are not moved in the corresponding movement directions, before synchronously controlling the needle and the looper to move, the control method further comprises:
unlocking the upper shaft drive structure and the lower shaft drive structure;
the moving direction of the upper shaft is adjusted by adjusting the moving direction of the first rotating shaft and/or the moving direction of the lower shaft is adjusted by adjusting the moving direction of the second rotating shaft.
7. The control method according to claim 4, wherein in a case where the needle and the looper are moved in the corresponding movement directions, before synchronously controlling the needle and the looper to move, the control method further comprises:
and acquiring a first preset rotating speed of the first rotating shaft and a second preset rotating speed of the second rotating shaft.
8. A control device of a sewing machine including a needle and a looper, characterized by comprising:
the first control unit is used for controlling the needle to move to a first preset initial position;
the second control unit is used for controlling the curved needle to move to a second preset initial position;
and the third control unit is used for synchronously controlling the needle and the curved needle to move, wherein the needle starts to move from the first preset initial position according to a first preset speed, and the curved needle starts to move from the second preset initial position according to a second preset speed.
9. A storage medium characterized by comprising a stored program, wherein the program executes the control method of any one of claims 1 to 7.
10. A processor, characterized in that the processor is configured to run a program, wherein the program is configured to execute the control method according to any one of claims 1 to 7 when running.
