摘要

Disclosed is an air blowing and sucking system for a roving frame. In the air blowing and sucking system, a table sucking opening (4) is provided on the lower end of each table sucking pipe (3), a rack (1) is provided with a continuous track (5) from a headstock to a tailstock, a trolley (6) is arranged on the track (5) in a matching manner, and an upper blowing and sucking draught fan (7) is fixed to the trolley (6); and a dust and impurity exhaust outlet (8) movably connected to a tailstock air sucking pipe (2) is provided on the rear end of the upper blowing and sucking draught fan (7), the upper blowing and sucking draught fan (7) is fixedly connected with an upper air blowing pipe (9), a table air blowing opening (10) is provided on the lower end of the upper air blowing pipe (9), the front end of the upper blowing and sucking draught fan (7) is connected to an air sucking elbow pipe (11), and a connector (12) adaptive to the upper end of the table sucking pipe (3) is provided on the lower end of the air sucking elbow pipe (11). An upper blowing and sucking draught fan (7) and a tailstock draught fan both adopt an intermittent running mode through electrical control, thereby being able to increase original air blowing and sucking effects and having a relatively obvious energy saving effect.
