Abstract

The invention discloses a double-needle loop sewing machine with a thread cutting structure, which comprises a base and a nose. The nose is provided with a first needle and a second needle capable of moving up and down. A first rotary hook operating with the first needle and a second rotary hook operating with the second needle are disposed in the base. The first needle, the second needle, the first rotary hook and the second rotary hook are driven to operate by a same motor. A first needle plate is disposed above the first rotary hook, and a second needle plate is disposed above the second rotary hook. A second thread cutter is disposed at the bottom of the second needle plate and comprises a second fixed blade and a second moving blade. A drive cam for driving the second moving blade isdisposed on an upper shaft, and a drive bar capable of moving with and separating from the drive cam is connected to the second moving blade. When the drive bar is operated with the drive cam, the drive cam drives the second moving blade to cut a thread.
