The rubber striking blocks on the support arm strike both sides of the curtain to discharge the dust attached to the curtain. At this time, the dust suction fan generates negative pressure outside the dust suction hood to absorb and transfer the dust, thereby realizing automatic cleaning of the curtain during the winding process.
