[0020] Thereby, the moving seat is the mounting part of the rotating device.

[0021] In some embodiments, the yarn cutting module includes a linear driving member, which is disposed on the movable seat and above the rotary driving member, and a driving end of the linear driving member is connected to the rotary driving member.

[0022] Therefore, by providing a linear drive to drive the lifting and lowering movement of the yarn cutting mechanism, the initial height of the yarn cutting mechanism can be adjusted.

[0023] In some embodiments, one end of the buffer is hinged on the moving seat.

[0024] Thus, the upper end of the buffer is connected to the movable seat, thereby supporting the weight of the yarn cutting mechanism.

[0025] In some embodiments, a second ear plate is provided at a side edge of the movable seat, a second hinge column is provided on one side surface of the second ear plate, and an upper end of the buffer is connected to the second hinge column.

[0026] Thus, the first hinge column is mounted by providing the second ear plate.

[0027] In some embodiments, the buffer is a spring.

[0028] Thus, the buffer member is provided as a spring, and its mounting structure can be simplified.

[0029] The beneficial effects of the utility model are mainly reflected in: the yarn cutting mechanism is driven to swing by the rotating driving member, and while swinging, the yarn cutting mechanism is buffered by the buffer member, which can offset its own weight, thereby ensuring that its rotation and swing are smooth. The angle of driving the rotation and swing is accurate and accurate, and the service life is extended.
