Problems solved by technology
[0002] At present, in the process of sewing clothing materials, lockstitch sewing machines have to go through the thread trimming process every time they change the sewing line. It will fall off, and after a long time, the thread will accumulate less and more, and the sewing machine oil near the rotary hook will contaminate the clothes, consume the sewing machine oil, and even cause poor lubrication

The invention belongs to the technical field of lockstitch sewing machine, and relates to a lint absorbing device of a lockstitch sewing machine. The lint absorbing device comprises a lockstitch sewing machine table plate and a rotating shuttle, wherein a lint absorber and an electromagnetic valve are fixed on the lower side of the lockstitch sewing machine table plate, an air charging joint of the electromagnetic valve is connected with an air charging guide pipe, an air discharging joint of the electromagnetic valve is connected with an air charging joint of the lint absorber through a guide pipe, a lint absorbing air pipe connected with the lint absorber is connected to a lint collection part of the rotary shuttle, an air discharging joint of the lint absorber is communicated with the air charging joint of the lint absorber through an inner channel, and the operation of the electromagnetic valve is controlled by a program of a controller. The lint absorbing device of the lockstitch sewing machine, disclosed by the invention has the advantages that an air source and assemblies are controlled by the controller to automatically absorb lint based on a pressure difference drainage principle of an airflow so that the automation degree is high; and the lint absorbing device is suitable for absorbing the lint in the lockstitch sewing machine.
Description
technical field [0001] The invention belongs to the technical field of locket sewing machines, in particular to a thread suction device for locket sewing machines. Background technique [0002] At present, in the process of sewing clothing materials, lockstitch sewing machines have to go through the thread trimming process every time they change the sewing line. It will fall off, and over time, the thread wool will accumulate, contaminate the sewing machine oil near the rotary hook, contaminate the clothing, consume the sewing machine oil, and even cause poor lubrication. Contents of the invention [0003] The object of the present invention is to provide a thread-absorbing device for a locket sewing machine that can timely absorb the thread hair generated by thread trimming. [0004] The purpose of the present invention is achieved like this: [0005] The thread and hair suction device of the lockstitch sewing machine includes a locket sewing machine table and a rotary ...
