  • Louver roller system with cam pin turning mechanism
    Patent number: 9493983
    Abstract: The invention discloses a louver roller system with a cam pin turning mechanism, including a base and a top cover, wherein a roller mechanism and a cam pin turning mechanism are mounted on the base, the roller mechanism is wound with ladder tapes, the roller mechanism is in axial connection with the cam pin turning mechanism, and the roller mechanism and the cam pin turning mechanism are driven to rotate by a square shaft. The roller mechanism controls horizontal rising and falling of secondary louver blades, and the roller within the roller mechanism rotates to wind or unwind the ladder tapes thereon and sequentially drives various secondary louver blades to rise and fall horizontally. When various secondary louver blades rise to a predetermined position, the roller drives the cam pin turning mechanism to bring a turning cylinder to rotate, so as to achieve turning of all louver blades.
