Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention will be defined more clearly.

[0026] Refer to figure 1 As shown, the system for opening bundled spun yarn back into fibers of the present invention includes:

[0027] The feeding device 1 includes a conveying mechanism 11 and a rotary clamping mechanism 12. The conveying mechanism 11 is used to feed the bundled staple fiber yarn recirculation 2 into the rotary clamping mechanism 12, and the rotary clamping mechanism 12 is arranged in the conveying mechanism 11. , And used to rotate and clamp the bundled spun yarn back to silk 2;

[0028] The loosening device 3 includes two loosening licker rollers 31 that rotate in cooperation with each other. The two loosening licker rollers 31...

Abstract

The invention discloses a system and a method for opening hard wastes of bunchy staple fiber yarns into fibers. The system comprises a feeding device and a debonding device, wherein the feeding device comprises a conveying mechanism and a rotating clamping mechanism; the conveying mechanism is used for feeding the hard wastes of bunchy staple fiber yarns into the rotating clamping mechanism; the rotating clamping mechanism is arranged at the tail end of the conveying mechanism and is used for rotating and clamping the hard wastes of bunchy staple fiber yarns; the debonding device comprises two debonding licker-ins which rotate and are matched with each other; the two debonding licker-ins are correspondingly arranged under the rotating clamping mechanism; the debonding device is used for rotating and brushing the free ends of the hard wastes of bunchy staple fiber yarns stretching out of the rotating clamping mechanism; a rotating speed of the rotating clamping mechanism is less than the rotating speed of the debonding licker-ins. The system can greatly reduce the damage to the fibers and has high opening efficiency and effect.

Description

Technical field [0001] The present invention relates to the technical field of waste reclaimed silk recycling, in particular to a system and method for opening bundled staple fiber yarn reclaimed fibers into fibers. Background technique [0002] The recycling of waste yarns for recycling is an important link in the textile and apparel industry chain. In the textile production process line, each process will produce a certain amount of by-products, such as the cotton lap in the opening process, the sliver and the roving return in the pre-spinning workshop, and the spun yarn in the post-spinning workshop. It also includes sizing, silk, etc., as well as yarn from discarded old clothes. Generally, the cotton roll tail, the sliver sliver and the roving yarn can be returned to the blowroom workshop for reopening and reuse, while the spun yarn cannot be returned for reopening and reuse. Because the cotton tail, sliver and roving yarn are loosely entangled fibers, the binding force bet...
