Abstract

The invention discloses a sewing machine dust collection device which comprises a dust collection barrel. An upper cover plate is arranged on the dust collection barrel; a rear suction inlet and a thread suction pipe connector are formed in the upper cover plate; a motor is arranged in the inner cavity of the dust collection barrel, and the output shaft of the motor is connected with a fan; an electromagnet is arranged on the outer side or the inner cavity of the dust collection barrel, a clamping arm is formed at one end of the electromagnet and is fixedly connected with a connecting pin, the connecting pin is connected with the free end of a rotating piece, the fixing end of the rotating piece is provided with a fixed pin, and the connecting pin can rotate around the fixed pin; the connecting pin is fixedly connected with a partition; the electromagnet drives the clamping arm to eject out, the clamping arm drives the connecting pin to rotate around the fixed pin, and the connecting pin drives the partition to rotate with the same to have the rear suction inlet covered. During operation of a thread suction pipe, suction force generated from the thread suction pipe can be increased instantly, the defect about insufficient suction force of the thread suction pipe is made up, and the suction force of a suction pipe and the thread suction pipe can satisfy the requirements of use.

Description

Technical field [0001] The invention relates to an accessory of a sewing machine, in particular to a dust collecting device of a sewing machine. Background technique [0002] The sewing machine will produce rags and thread ends during the sewing process, and a dust collecting device is required to collect the rags and thread ends. Existing dust collection devices generally include a dust suction tube for collecting rags and a wire suction tube for collecting thread ends. Because the volume of the rag and the thread is different, the diameter of the suction pipe for collecting the rag and the suction pipe for collecting the thread is also different, and the diameter of the suction pipe is much larger than the diameter of the suction pipe. It is precisely because of the large difference between the diameters of the suction pipe and the suction pipe that not only the suction force generated by the suction pipe is greater than the suction force generated by the suction pipe, but al...
