The invention provides a control method and system for automatically switching a sewing mode in a sewing machine. When sewing is performed, a current thickness value of a sewing material at a needle is obtained in real time, and it is judged that the sewing material is located in the n sewing material thickness interval of N sewing material thickness intervals according to the current thickness value; a current angle value of a main shaft of the sewing machine is also obtained, the current angle value of the main shaft of the sewing machine is compared with the n main shaft angle value, and if the current angle value equals the n main shaft angle value, sewing is performed normally; if the current angle value does not equal the n main shaft angle value, a clutch mechanism is controlled to move to make a feeding eccentric gear relatively separated from the main shaft of the sewing machine, the main shaft of the sewing machine is driven to rotate until the current angle value of the main shaft of the sewing machine equals the n positioning angle value, and then the clutch mechanism is controlled to move again to make the feeding eccentric gear locked with the mainshaft of the sewing machine to execute sewing. The control method and system for automatically switching the sewing mode in the sewing machine greatly enhance the adaptability of the sewing machine to different fabrics.
Description
technical field [0001] The invention relates to the technical field of sewing machines, in particular to a control system and a control method for automatically switching sewing modes in a sewing machine. Background technique [0002] In the cloth feeding mechanism of the existing sewing machine, its feeding eccentric wheel has an integral structure, see figure 1 As shown, the cloth feeding eccentric wheel 11 includes a cloth feeding eccentric part and a tooth lifting eccentric part. The cloth feeding eccentric wheel 11 is integrally fixed on the main shaft 14 and its position angle cannot be adjusted. The cloth feeding eccentric part 0 is equipped with a cloth feeding connecting rod 12, The teeth lifting connecting rod 13 is matched with the teeth lifting eccentric part. The tooth lifting eccentric part transmits the power to the tooth lifting crank 15 through the connecting rod transmission structure, and the cloth feeding eccentric part transmits the power to the bracket...
