A button conveying device can reduce the sewing cost and reduce the user's work and management burden. The button conveying device (1) moves the mounting table (12) to the button mounting table (11) by the operation of the driving mechanism (13) driven by the driving device (14) after the button is placed at the button loading position. At the button supply position, the buttons on the button placing table (11) are clamped by the button clamping device (5); the button placing table has a plurality of button placing arms (111, 112) corresponding to the button holding pins (15, 16) The button placing arm is vertically provided with each button holding pin (15, 16) on the upper surface and can move independently along the upper surface of the mounting table, and also has fixing members (111c, 112c) for fixing each button placing arm at an arbitrary position ), by releasing the fixing of each button placing arm by the fixing member, and moving the plurality of button placing arms, the distance between the plurality of button holding pins can be adjusted.

The invention provides a device for detecting the amount of bottom thread of a sewing machine. The sewing machine comprises a bottom plate, a rotating shuttle and an electronic control module, wherein the rotating shuttle comprises a shuttle shell and a shuttle core; the shuttle core comprises a winding post and two flanges; at least one flange in the two flanges is provided with a first surface part and a second surface part on the outer surface; a light hole is formed on the outer wall of the shuttle shell; the first surface part or the second surface part is exposed outside from the light hole; the sewing machine also comprises a sensor fixed in the bottom plate; the sensor comprises a transmitter used for transmitting light, and a receiver used for receiving light; the receiver and the transmitter of the sensor just face to the first surface part or the second surface part exposed outside from the light hole, and the light reflection capabilities of the first surface part and the second surface part are different from each other; the sensor is connected with a signal processing module; the signal processing module is connected with the electronic control module. The device for detecting the amount of the bottom thread of the sewing machine is capable of timely detecting whether the bottom thread is used up or not in real time.

The invention relates to a paillette feeding device comprising a cylinder, a movable guide plate, a motor, a motor plate, shifting forks and a dead knife, wherein the motor plate and the movable plate are linked and cooperated; the dead knife is arranged on the bottom of the motor plate; the motor is arranged on the motor plate; the dead knife is provided with a paillette path; two shifting forks are both connected with the output shaft of the motor; the paillette path comprises a first paillette path and a second paillette path; the other ends relative to the ends connected with the output shaft of the motor, of the two shifting forks, are toggling ends; and the toggling ends of the two shifting forks are respectively toggled in the first paillette path and the second paillette path to transmit the paillette. The paillette feeding device also comprises two spacing devices for preventing the two shifting forks from toggling. By the above technical scheme, the invention provides the paillette feeding device which can simultaneously transmit two different paillettes so as to improve sewing efficiency.
