The strands are twisted with the rotation of the swing arm. The strands are twisted once by the first swing arm and twisted again by the second swing arm. It is called a double twisting machine. The production efficiency is low, especially the twist of thin rope strands requires a large twist (the number of twists on a strand length of one meter is the definition of twist, the unit is: twist / meter), and the rope production capacity is extremely low.

4. The quadruple twisting device for a frame-type rope making machine according to claim 1, characterized in that: The wire roller assembly (4) comprises a cradle frame (41) and a plurality of wire roller shafts (43) fixedly connected to the cradle frame (41), wire rollers (42) being mounted on the wire roller shafts (43), and the cradle frame (41) is axially connected to a swing arm shaft (12) via a bearing.

5. The quadruple twisting device for a frame-type rope making machine according to claim 4, characterized in that: A strand die opening (45) is fixedly connected to one side of the twisting assembly (1) of the cradle frame (41) close to the discharge end, and a strand thread passing hole is formed on the strand die opening (45).

6. A method for using the quadruple twisting device for a frame-type rope making machine according to claim 1, characterized in that: The steps include: a. Drive the swing arm shaft and the swing arm sleeve to rotate in opposite directions through the driving device; b. After the multiple silk threads in the wire roller assembly are plied, they first pass through the swing arm shaft of the twisting assembly at the discharge end and then pass through the short swing arm passing wheel. They are twisted once through the rotation of the short swing arm and then enter the twisting assembly at the double twisting end; c. The strands pass through the short swing arm of the twisting assembly at the twisting end and then pass through the swing arm shaft through the wire wheel, and are twisted twice by rotating the short swing arm of the twisting assembly at the twisting end; d. Then the strands pass around the swing arm sleeve passing wheel and then the long swing arm passing wheel, and are twisted three times through the reverse rotation of the long swing arm, and then return to the twisting assembly at the discharge end; e. The strands pass through the long swing arm of the twisting assembly at the discharge end, and four twists are achieved through the reverse rotation of the long swing arm of the twisting assembly at the discharge end; f. Finally, the strands of thread go around the swing arm sleeve in the twisting assembly at the discharge end and pass through the wire wheel before exiting.
