Abstract
The utility model discloses a thread sweeping mechanism of an electronic bartacking machine. The thread sweeping mechanism comprises a thread sweeping arm used for sweeping threads and arranged on a thread sweeping arm installation support in a rotating mode, and a thread sweeping connection crank and a pressing plate connection crank are coaxially arranged in a machine head in a rotating mode. The movable end of the thread sweeping connection crank drives the thread sweeping arm to rotate through a connecting plate. A connecting plate support is arranged at the tail portion of the machine head in a rotating mode, one end of the connecting plate support drives the thread sweeping connection crank to rotate through the connecting plate, and the other end of the connecting plate support is matched with a drive cam through a roller. The drive cam drives the connecting plate support to rotate, the connecting plate support drives the thread sweeping connection crank to rotate through a connecting rod, and the thread sweeping connection crank drives the thread sweeping arm to sweep threads through the connecting support plate and a thread sweeping support plate. The thread sweeping mechanism has the advantages of being simple in structure and convenient to install.
