AI Technical Summary
Technical Problem
The speed range and precision of the motors in existing air curtain equipment are limited, making it difficult to achieve small and precise adjustments to flow rate and velocity, and the response speed is slow.
Method used
The design employs a combination of a rotating screw and an air guide impeller. The rotating screw drives the air guide impeller to move and adjust the flow area. Combined with the structure of a support plate, transmission gears, and telescopic top cylinder, it enables flexible control of airflow and velocity.
Benefits of technology
It achieves precise regulation of airflow and velocity, forming a uniform air barrier that effectively isolates dust and improves regulation response speed and accuracy.

Abstract
The utility model discloses dustproof integrated regulation and control equipment capable of automatically opening and closing ventilation, which relates to the technical field of ventilation and air exchange equipment and comprises an air curtain body, two air duct shells are fixedly mounted at the top end of the air curtain body, and regulation components are arranged in the air duct shells. The adjusting assembly comprises supporting discs, guide rods, a rotating screw rod and air guide impellers, the two air guide impellers are both connected with the rotating screw rod in a penetrating mode, a groove is formed in the top end of the rotating screw rod, the multiple guide rods are installed between the supporting discs, the guide rods play a supporting role, and the two air guide impellers rotate synchronously; a butt joint handle generates pulling force on a diagonal draw bar, the diagonal draw bar inclines at the side end of an air duct shell, the diagonal draw bar moving in the inclined direction pulls the top ends of telescopic top cylinders, the two telescopic top cylinders are mutually inserted into the top ends of positioning sleeves, a supporting disc is limited, and when a rotating screw rod is rotated to adjust the distance between two air guide impellers, the supporting disc is prevented from rotating; and the adjustment precision is influenced.
