[0001] The utility model relates to the technical field of tire bead wire processing, in particular to an automatic dust removal device for a wire drawing straightener. Background Art

[0002] The tire bead wire needs to go through multiple processes such as mechanical rust removal, drawing, copper plating, etc. during the production process. Therefore, the steel wire is easy to bend and deform, and needs to be corrected by a straightener to ensure the straightness of the steel wire.

[0003] When the steel wire passes through the straightener, wire drawing chips are easily generated. The existing device uses the exhaust fan to suck the wire drawing chips into the top of the filter screen, which is convenient for cleaning. However, when the wire drawing chips enter the top of the filter screen, they are easily accumulated on the top surface of the filter screen, which can easily cause the top of the filter screen to be blocked, thereby reducing the wind force of the exhaust fan and reducing the effect of wire drawing chip treatment.
