[0047] The implementation principle of a plastic processing waste gas extraction device in an embodiment of the present application is as follows: when in use, the fan 1 is started, and the fan 1 absorbs the plastic processing waste gas onto one of the two ventilation pipes 3, and filters it through one of the two filter screens 21 to remove dust in the plastic processing waste gas. However, during use, the filter screen 21 will be blocked by dust, affecting the filtering effect, so the filter screen 21 needs to be cleaned. At this time, the first motor 24 is started, and the first motor 24 drives the connecting block 25 to rotate 180 degrees. The connecting block 25 drives both filtering devices to rotate 180 degrees, so that the other filter screen 21 of the two filters 21 and the other frame 22 of the two frames 22 replace the used filter screen 21 and frame 22.
