Intermittent gear turning mechanism with a blind pulley mechanism

摘要

The invention discloses a louver roller system with an intermittent gear turning mechanism, comprising a base and a top cover, wherein a roller mechanism and an intermittent gear turning mechanism are mounted on the base, the roller mechanism is wound with ladder tapes, the roller mechanism is in axial connection with the intermittent gear turning mechanism, and the roller mechanism and the intermittent gear 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 intermittent gear turning mechanism drives a turning cylinder to rotate, so as to achieve turning of all louver blades.
