The invention provides a thread bonding device and a sewing machine with the same. The thread bonding device comprises a thread passing structure, a thread bonding structure and a driving structure, wherein a thread passing part is arranged on the thread passing structure and used for allowing a sewing thread to pass through; the thread bonding structure is rotationally arranged on the thread passing structure, the thread bonding structure is provided with a thread bonding part, an initial position and a thread bonding position, and when the thread bonding structure is positioned at the initial position, the thread bonding part is positioned at the thread passing part; when the thread bonding structure is positioned at the thread bonding position, the thread bonding part is used for pulling out the sewing thread at the thread passing part; a driving end of the driving structure is at least partially propped against the thread bonding structure, so that the thread bonding structure is pushed to move by the driving end and drives the thread bonding part to pull out the sewing thread. With the adoption of the technical scheme, the technical problem that sewing starting and needle breakage are easily caused when a bird nest prevention device works in the prior art can be solved.
Description
technical field [0001] The invention relates to the technical field of sewing machines, in particular to a thread-tying device and a sewing machine with the same. Background technique [0002] At present, sewing machine is to use one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interwoven or sewed up. In order to prevent thread balls from appearing in the sewing thread, an anti-bird's nest device is installed on the sewing machine. When the anti-bird's nest device in the prior art is working, the machine needle needs to use a longer sewing thread in a short period of time, so the technical problem of broken needles when sewing often occurs. Contents of the invention [0003] The main purpose of the present invention is to provide a thread-tying device and a sewing machine with it, so as to solve the technical problem that the bird's nest preventing device in the prior art is likely to cause t...
