Abstract

The invention discloses a bio-based composite monofilament spinning and winding device, relates to the technical field of spinning production, and solves the technical problem of non-uniform cooling defect of bio-based composite spinning in cross air blowing cooling in related technologies. The device comprises a first extruding machine, a second extruding machine, a spinning box body and an annular blowing assembly, the first extruding machine and the second extruding machine are communicated with a composite spinning assembly of the spinning box body respectively, composite monofilaments are sprayed out through a spinneret plate of the spinning box body, and the annular blowing assembly comprises a central annular blowing cylinder, a central annular blowing box, an outer annular blowing cylinder and an outer annular blowing box. According to the device, the curing forming conditions of filaments in the space can be basically the same, the uniformity of the structure and the linear density is facilitated, the defect that cooling is not uniform due to the fact that side blowing cooling is adopted is overcome, the cooling efficiency is improved, and the service life of the device is prolonged. The cooling of the bio-based composite spinning is facilitated.

Description

technical field [0001] The invention relates to the technical field of spinning production, in particular to a bio-based composite monofilament spinning and winding device. Background technique [0002] The composite spinning product made of bio-based materials can be degraded after use, which is beneficial to environmental protection. At present, bio-based PLA chips and bio-based polyamide XX chips can be produced on a large scale, and the advantages of their respective bio-based polymers can be combined to form composite monofilaments. After passing through the spinneret of the composite spinning box, the tow must be cooled by ring blowing. The current side blowing cooling and forming has the defect of uneven cooling of the single filament due to the distance from the air window, and it is in urgent need of improvement. SUMMARY OF THE INVENTION [0003] The present application provides a bio-based composite monofilament spinning and winding device, which solves the tech...
