Spinning traction device for modified fiber

Abstract

The invention discloses a spinning traction device for modified fiber. The device comprises a supporting main frame and a bobbin fixing mechanism, an H-shaped plate frame fixedly connected with the supporting main frame is arranged above the bobbin fixing mechanism, a silk yarn winding mechanism is arranged on the H-shaped plate frame, a tensioning waxing mechanism and a reel mechanism are arranged above the silk yarn winding mechanism, the H-shaped plate frame comprises two vertical supporting plates and a cavity rotating disc, the side curve face of the cavity rotating disc is provided withmultiple polishing inclined cutting grooves, a C-shaped clamping groove is formed in the inner wall of the upper end of the cavity rotating disc, a rotating round plate is arranged in the C-shaped annular clamping groove, the silk yarn winding mechanism comprises a coiling plate and threading holes which are formed in the edge of the coiling plate and are annularly distributed, a drive motor is arranged in the cavity rotating disc, an output shaft of the drive motor is fixedly connected with the rotating round plate, winding disorder between spinning bobbins can be prevented, under the large external force, the bobbins can be subject to self-adjusting rotation, and the breakage of spinning in the traction process can be reduced.

Description

technical field [0001] The invention relates to the technical field of modified fibers, in particular to a spinning and pulling device for modified fibers. Background technique [0002] Modified fibers refer to chemical fibers made by denaturing fibers by chemical or physical methods. Physically modified fibers include shaped fibers, deformed fibers and composite fibers. Fibers modified by chemical methods include grafted fibers, copolymerized fibers, and fibers modified by chemical post-treatment. [0003] Modification methods include: (1) chemical methods, such as copolymerization or graft copolymerization; (2) physical methods, such as blending or physical addition of certain modifiers. These methods have been widely used, and many new varieties of modified chemical fibers have been successfully developed, such as high wet modulus viscose fiber, cationic dyeable polyester fiber (CDP fiber, ECDP fiber), acrylonitrile-vinyl chloride Copolymer fiber (acrylic fiber), water...

AI Technical Summary

Problems solved by technology

[0006] (1) The spinning is subject to friction during traction, and it is prone to winding and breaking;

[0007] (2) The tension effect of spinning during winding cannot be adjusted, and the speed of winding cannot be adjusted normally
