step S101, controlling a needle to move to a first preset initial position;

step S102, controlling the curved needle to move to a second preset initial position;

step S103, synchronously controlling the needle and the looper to move, wherein the needle starts to move from the first predetermined initial position at a first predetermined speed, and the looper starts to move from the second predetermined initial position at a second predetermined speed.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.

In the control method, after the needle is controlled to move to the first preset initial position and the looper is controlled to move to the second preset initial position, the needle and the looper are synchronously controlled to move, namely, the needle starts to move from the first preset initial position according to the first preset speed, and the looper starts to move from the second preset initial position according to the second preset speed. The method adjusts the needle to the preset initial position, namely the first initial position, and adjusts the looper to the preset initial position before synchronously controlling the needle and the looper, so that the movement initial positions of the needle and the looper are ensured to be the preset positions, and the problem that the needle and the looper are difficult to synchronously move due to the fact that the movement initial positions of the needle and the looper are not the preset initial positions in the prior art is solved. In addition, the moving direction or position of the upper shaft and the lower shaft does not need to be manually adjusted by means of an additional tool, and the efficiency is high.

In the working process of the sewing machine, the needle and the looper need to move synchronously, the synchronous movement includes the movement direction correspondence of the needle and the looper, and also includes the movement speed matching of the needle and the looper, in order to further ensure that the needle and the looper can move according to the corresponding movement direction, and further ensure the synchronous movement of the needle and the looper, in an embodiment of the application, before synchronously controlling the movement of the needle and the looper, the control method further includes: controlling the movement of the needle and the curved needle at the same time; and detecting whether the machine needle and the curved needle move according to the corresponding movement directions. Before the movement of the needle and the curved needle is synchronously controlled, the method simultaneously controls the needle and the curved needle to start moving from the corresponding preset initial positions, and detects the movement directions of the needle and the curved needle, so that whether the movement of the needle and the curved needle needs to be adjusted is determined, and the subsequent movement of the needle and the curved needle can be synchronously controlled.

Whether the machine needle and the curved needle move according to the corresponding moving directions means whether the moving directions of the machine needle and the curved needle correspond to each other, and the corresponding specific situation can be determined according to the specific actual situation, for example, in the conventional sewing process, the upward movement of the machine needle and the leftward movement of the curved needle correspond to each other, and the downward movement of the machine needle and the rightward movement of the curved needle correspond to each other, and for this case, detecting whether the machine needle and the curved needle move according to the corresponding moving directions includes: 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.

Of course, the correspondence relationship between the moving direction of the needle and the moving direction of the looper in the present application is not limited to the above-mentioned conventional relationship, and may be other correspondence relationships, and needs to be determined according to the structure of the sewing machine.

In a case where the needle and the looper move in the corresponding movement directions, before synchronously controlling the needle and the looper to move, the control method further includes: the control method further comprises the following steps: and acquiring a first preset rotating speed of the first rotating shaft and a second preset rotating speed of the second rotating shaft, so that the needle moves according to a preset moving speed, and the bent needle moves according to a preset speed, thereby further ensuring the synchronous movement of the needle and the bent needle.
