Description

Technical Field

[0001] The utility model relates to the field of two-for-one twisting devices, in particular to a nylon fiber two-for-one twisting device. Background Art

[0002] Nylon fiber is a synthetic fiber with high elongation at break, low modulus and high elastic recovery rate. Nylon fiber needs to use a two-for-one twister in the production and processing process. The two-for-one twister is a twisting device that can twist and bond two or more strands of fiber into strands, thereby enhancing the performance of the original fiber.

[0003] Chinese patent number CN202122278148.X discloses a nylon fiber double twister, including a base, a power mechanism, multiple groups of lead screw shafts, multiple groups of sliders, a lifting plate, multiple groups of support rods, a double twister body, a partition, a drying box, an air suction machine, an air suction pipe, an exhaust pipe, a mounting block, a high-density absorbent cotton, a temperature controller and a heating rod. The multiple groups of lead screw shafts are rotatably connected to the front and rear sides of the left and right ends of the base through the power mechanism, the threads of the lead screw shafts on the left and right sides are opposite, the multiple groups of sliders are respectively screwed to the multiple groups of lead screw shafts, and the multiple groups of sliders are respectively fixed at the left and right ends of the lifting plate, the multiple groups of support rods are evenly fixed at the top of the lifting plate, and the double twister body is fixed at the top of the multiple groups of support rods, a chamber is arranged inside the double twister body, a box door is arranged at the front end of the double twister body, and the partition is fixed in the middle of the chamber of the double twister body.

[0004] From the above, it can be seen that the air in the drying box is dried, and the dried air is discharged back into the main body of the twister from the exhaust pipe, which avoids the humid air from damaging the twisting elements inside the main body of the twister, and improves the service life of the device. By setting the mounting block, it is convenient to regularly replace the high-density absorbent cotton to ensure the water absorption effect of the high-density absorbent cotton. However, this case still has the following shortcomings: when twisting nylon fibers, multiple strands of nylon fibers need to be twisted together. When the nylon specifications are inconsistent, the twisting amplitude also needs to be adjusted accordingly to ensure that multiple strands of nylon fibers are precisely fitted together and not easy to loosen.

[0005] Therefore, a nylon fiber two-for-one twisting device is proposed to solve the above problems. Utility Model Content
