The sub-louver blades (91, 92, 93) can turn over along with the main louver blades (90), and can also turn over relative to the main louver blades (90). A driver (4) and a lift turner (3) of the window blind are arranged in a top rail (1); a hexagonal shaft (2) passes through the driver (4) and the lift turner (3). A connecting bead chain (42) of the driver (4) rotates the hexagonal shaft (2) through the driver (4), thereby driving the lift turner (3) to rotate. A lift cord (7) passes through a louver blade assembly (9). An upper end of the lift cord (7) is connected to a lift wheel (32) in the lift turner (3), and a lower end thereof is connected to a main bottom rail (100). Upper ends of front and rear ropes of a sub-ladder tape pass through a ladder tape hole (386) of a base (38) of the lift turner (3), and are embedded into an annular groove of a turnover drum (354) of a roller mechanism (35) of the lift turner (3), and then enter a top hole (3545) of the turnover drum (354) and are fixed in the roller annular groove through a pin (35113).

Ladder tapes (80, 81, 82, 83) are wound on the roller mechanism (35). The roller mechanism (35) and the tooth clutch turnover mechanism (36) are connected in an axial direction. The square shaft (2) drives the roller mechanism (35) and the tooth clutch turnover mechanism (36) to rotate.
A window blind roller system with an intermittent gear turnover mechanism comprises a base (38) and a top cap (39). A roller mechanism (35) and an intermittent gear turnover mechanism (36) are mounted on the base (38). The roller mechanism (35) and the intermittent gear turnover mechanism (36) are connected in an axial direction. The roller mechanism (35) and the intermittent gear turnover mechanism (36) are driven by a square shaft (2) to rotate. The roller mechanism (35) controls horizontal ascending and descending of sub-louver blades (91, 92, 93). Rollers (351, 352, 353) are disposed inside the roller mechanism (35), and ladder tapes (81, 82, 83) are wound on the rollers (351, 352, 353). The ladder tapes (81, 82, 83) are connected to the louver blades (91, 92, 93). The rollers (351, 352, 353) drive the ladder tapes (81, 82, 83) wound thereon to wind up or be loose, so as to sequentially drive horizontal ascending or descending of the sub-louver blades (91, 92, 93). When each sub-louver blade (91, 92, 93) is lifted to a predetermined position, the intermittent gear turnover mechanism (36) drives the turnover drum (354) to rotate, hence implementing turning of all blades (90, 91, 92, 93).

The roller mechanism (35) and the cam pin turnover mechanism (36) are connected in an axial direction; the roller mechanism (35) and the cam pin turnover mechanism (36) are driven by a square shaft (2) to rotate. The roller mechanism (35) controls horizontal ascending and descending of sub-louver blades. A roller inside the roller mechanism (35) rotates, so that the ladder tapes wound thereon wind up or become loose, and sequentially drive horizontal ascending or descending of the sub-louver blades. When each sub-louver blade is lifted to a predetermined position, the roller drives the cam pin turnover mechanism (36) to rotate the turnover drum, hence implementing turning of all louver blades.
