Modularized combined-type melt-spinning filament double-sided air blast cooling device

Abstract

Disclosed is a modularized combined-type melt-spinning filament double-sided air blast cooling device. The device comprises a box body, a camera mechanism, and an air conditioner air introducing box, wherein fiber air blasting cooling cavities are arranged in the box body from left to right, air cooling cavities are formed corresponding to the left sides and right sides of the fiber air blasting cooling cavities, a thermal insulation bin enclosure frame is arranged at the top of the box body, the area located in the thermal insulation bin enclosure frame is a thermal insulation bin, a detection door is arranged corresponding to the front sides of all the fiber air blasting cooling cavities, and illuminating mechanisms are arranged at the upper portions of the left cavity walls and the right cavity walls of the fiber air blasting cooling cavities; the camera mechanism is arranged on the side, back to the right cavity walls of the fiber air blasting cooling cavities, of the left cavity walls of the fiber air blasting cooling cavities, or the side, back to the left cavity walls of the fiber air blasting cooling cavities, of the right cavity walls of the fiber air blasting cooling cavities, the air conditioner air introducing box is fixed to the box body, the box cavity of the air conditioner air introducing box is communicated with the air cooling cavities, and an air conditioner air inlet pipe at the left end of the air conditioner air introducing box is in pipeline connection with an air conditioner air supplying device. A uniform cooling effect between several strands of single-stranded fiber is guaranteed; the occupied space is saved, and the spinning efficiency is improved; the spinning effect is guaranteed; detection and protection are conveniently conducted.

Description

technical field [0001] The invention belongs to the technical field of synthetic fiber production equipment, and in particular relates to a modular combined double-sided air blowing and cooling device for melt-spun filaments. Background technique [0002] The aforementioned melt-spun filament is also called melt-spinning, which is to extrude the high polymer spinning melt such as PA or PE from the spinneret hole of the spinneret of the spinning machine, and the extruded melt is fine The stream is cooled and stretched by blowing in turn, and finally solidified into filaments, which are used as raw filaments for post-spinning and drafting or other purposes. The aforementioned double-sided blowing cooling device belongs to the category of side blowing cooling devices. [0003] As known in the industry, because the thin and dense melt strands just extruded from the spinneret holes on the spinneret are in a high-temperature molten state because they have not been solidified and ...

AI Technical Summary

Problems solved by technology

[0007]The tests done by the applicant show that: the above-mentioned modular combined melt-spun filament double-sided blowing cooling device can fully make up for the drawbacks of the aforementioned single-sided blowing cooling device , but there are technical bottleneck factors, specifically, compared to single-sided air blowing, since the thermal insulation bin corresponding to the spinneret and the fiber air cooling corresponding to the thermal insulation bin are both in a closed state, only the lower part of the fiber air cooling chamber The air outlet of the air outlet is connected with the outside world, so whether the working condition of the spinneret is normal or not can not be visually seen by the online workers

The applicant has done extensive literature search, but in the Chinese and foreign patents and non-patent literature disclosed so far, there is no enlightenment to solve the aforementioned technical bottleneck
