Description
Technical field
The utility model relates to chemical fiber machinery field, especially relates to a kind of drawing-off/dry silk device, the function of integrated multi-roll drafting machine and drafting heat box.
Background technology
In the production process of chemical fibre, the drawing-off of silk is very important link with being dried, and such as terylene, the polypropylene fibre of molten spinning, has corresponding draft process and equipment; And the acrylic fibers that solution spins, viscose not only need drawing-off, but also relate to dry.With respect to conventional fibre, the requirement of the drawing-off of high-performance fiber and dry counter extensioin and drying equipment is more harsh, such as high-performance polyethylene fibres, need in dry link that the time of staying is long, equipment is airtight, air quantity is little so that dry completely, containing solvent gas do not leak, organic efficiency is high; In drafting process, need drawing machine rotating speed steadily, accurately, drafting heat box temperature is even, stable.For realizing above-mentioned technique needs, this field professional carries out a large amount of research, successfully develops the various equipment with feature, and is applied in practice is produced.
Such as the drying equipment using in production process of viscose fiber, for a pair of have each other that certain angle is arranged, diameter more greatly, long cylindrical hot-rolling, in the time that this rotates hot-rolling, silk can be walked thereon twist, and a few are dried.This equipment is mainly applicable to the dry of moisture silk, and the dry water vapour producing can not produce adverse effect to environment; If contain organic liquid in silk, need equipment to propose airtight requirement, this kind of equipment cannot be satisfied the demand.
In patent CN20098533Y, disclose a kind of perpendicular row drying box, utilized and lengthen distance between godet roller, increased the stroke of tow, utilized the hot blast of Wind Volume to be dried silk.Although this kind equipment efficiently solves the inhomogeneous problem of hot case internal temperature, use the hot air of Wind Volume, will cause the concentration of solvent vapour on the low side, be unfavorable for separation and the recovery in rear road, and further increase after godet roller quantity when this equipment, equipment size will increase, and the uniform distribution that causes wind is affected.
A kind of hot air drier is disclosed in patent CN101135535A, by extending distance between godet roller, increase tow stroke, but this utility model has been used 2 motors to drag upper and lower 2 row's godet rollers, there is the problem of godet roller velocity deviation, and this hot case is still and adopts the hot blast of Wind Volume to be dried silk, be unfavorable for the recovery of solvent, there is the problem identical with aforementioned utility model.
Be more than the roughly introduction about current fiber drying equipment, briefly explain again draft apparatus below.
In terylene is produced, use and most often with some, hot-rolling is realized to drawing-off, speed can reach thousands of ms/min, it is very fast that this kind of equipment is applicable to rate of deformation, and the macromolecular material that drafting tension is lower, such as the drawing-off of the conventional chemical fibres such as terylene POY filament, polypropylene fibre, polyamide fibre, and the drawing-off of staple fibre and high strength yarn need to be used multi-roll drafting machine and drafting heat box to be used in conjunction with.
Such as each hot case of a kind of high-module high-strength polyethylene fibre double air channel drafting that discloses in patent CN101144199A and patent CN201077870Y, use hot-air as heating agent, use blower fan directly silk to be heated by strong convection.This kind equipment time must be considered being uniformly distributed of wind in design, guarantee temperature evenly, also need the defect of considering that air heat content is very low simultaneously, therefore this kind equipment complex structure, and must being used in conjunction with drawing machine, such as seven roller drawing machines.At patent CN200710133409.0, CN200720042564.7, a kind of seven (five) roller drawing machines are all disclosed in CN200420049661.5, ensure the steady and accurate of its rotation from various structural designs, its use principle is to increase the frictional force to tow by multiple parallel drafting rollers, ensures that tow does not produce slip in the time of drawing-off.
Above-mentioned draft apparatus in use, is all at least one drawing machines of each configuration before and after drafting heat box, utilizes the speed difference of drawing machine, realizes the drawing-off to tow.The use principle of the hot case of this class and drawing machine does not all change, only to improve on design and level of processing, if need multiple tracks drawing-off in technique, tow is inevitably cooled in the time entering lower one drawing-off, and then it is heated to enter hot case, not only cause heat loss, and counter extensioin is unfavorable.
Especially it is worth mentioning that, in patent CN100379914C, disclose a kind of baking oven of drawing fibres at elevated temp, the difference of itself and aforesaid dry heat case maximum with baking oven in godet roller be drive, can drawing-off when dry to tow thereby can realize.But this hot case still uses Wind Volume Hot-blast Heating, in temperature homogeneity and tow is stablized to drawing-off all can exert an influence.
Given this utility model is proposed.
