Multi-path air supply filtering device for winding head

The utility model discloses a multi-path air supply filter device for winding heads, which comprises a frame, winding heads and a main air pipe, the winding heads are mounted on the surface of the frame, and an air supply pipe and an exhaust pipe are arranged between the main air pipe and the air inlet ends of the winding heads. A connecting pipe is installed between the air supply pipe and the exhaust pipe, a filter A is arranged in the connecting pipe, and when the filter A in the connecting pipe breaks down to cause air pressure unbalance, an air pressure monitor monitors that the pressure is abnormal and changes, and an electromagnetic three-way valve is regulated and controlled through an external control assembly; the air source of the connecting pipe is disconnected and conveyed through the flow dividing pipe and the filter B, the influence on production equipment is reduced, at the moment, the valve can be closed, the connecting pipe and the filter A are independently disassembled and overhauled, and
