Abstract
The utility model specifically discloses a kind of thermal-insulating type spinnerets, and described spinnerets is oval, comprises spinnerette body, spinnerette body is provided with spinneret orifice; Spinnerette body is provided with one and by the peripheral air channel led in the middle part of spinnerets of spinnerets, the spinnerette body in region, air channel can arrange spinneret orifice; Described spinneret orifice comprises guide hole import counterbore, the lower end of guide hole import counterbore is communicated with for guide hole, the microporous connectivity in guide hole and spinneret orifice; The spinneret orifice of the described lower regions separated by air channel is connected by reinforcement in respective region.The high-temperature fusant that described spinnerets sprays reaches technological requirement with certain whole uniform cooling in journey of spinning and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree in official hour, thus makes spinning effect better.
Description
Technical field
The utility model relates to spinning field, particularly relates to a kind of thermal-insulating type spinnerets.
Background technology
Spinnerets is also known as spinning cap, the high polymer molten of viscous state or solution can be transformed into the thread having particular cross section shape by spinnerets by spinneret orifice, strand is formed after setting medium is as air or coagulating bath solidification, the spinnerets of current production dawn silk is generally circular, during lateral blowing, wind area is little, ventilative weak effect, cooling effect is not good, can produce the problem that the broken end of fiber, lousiness and Color are uneven.
Simultaneously common spinneret orifice of the prior art, is generally straight-through flexible, is unfavorable for that melt distributes even, while melt outlet place there is the phenomenon that swells, even melt fracture, causes broken end.
Spinnerets is as the indispensable precise part of spinning machine, and its shape and feature are the essential condition ensureing fibrous finished product quality.
Existing spinnerets in use easily blocks spinneret orifice because of impurity, the poor product quality produced, and impact uses normally, can not meet actual production and market demand.In actual production, in order to improve production capacity, large tow spinning spinning is applied in various different types of fiber species, and in the spinning process of high-viscosity melt, due to spinning solution transfer or metering time due to the fluctuation of a variety of causes occurrence temperature, thus cause the related properties such as apparent viscosity to change, in the process of the large bunch fiber of spinning, to waft the problem such as silk, adhesion at die orifice exit, thus affect the shaping uniformity of large bunch fiber strand.
Utility model content
The utility model is exactly the deficiency that will overcome existing spinnerets, provides a kind of thermal-insulating type spinnerets, and it is little that this spinnerets both can solve wind area when crosswind blows, ventilative weak effect, not good the asking of cooling effect; When spinning, because there is heat preservation channel, portal temperature and the apparent viscosity of high viscosity spinning melt can be controlled, waft silk, the adhesion problems of strand at die orifice exit place can be improved, large bunch fiber strand uniform in shaping can be improved; Solve the uneven phenomenon often breaking end with melt, block of melt simultaneously.
The utility model have employed following technical scheme:
A kind of thermal-insulating type spinnerets, described spinnerets is oval, comprises spinnerette body (1), spinnerette body (1) is provided with spinneret orifice (2); Described spinnerets main body (1) is provided with heat preservation channel (3) around spinneret orifice (2) surrounding, spinnerets main body (1) is provided with the import (11) of the thermal insulation medium connected with heat preservation channel and exports (12); Described spinneret orifice (2) comprises guide hole import counterbore (4), the lower end of guide hole import counterbore (4) is communicated with for guide hole (5), and guide hole (5) is communicated with the micropore (6) in spinneret orifice (4); Connected by reinforcement (8) between described spinneret orifice (2); The top of described spinnerette body (1) is provided with filter screen fixed frame (9) and is arranged on the cylinder type filter net (10) in filter screen fixed frame (9).
Further, the pitch-row such as described spinneret orifice (2) arrangement.
Further, between described guide hole (5) and micropore (6), be provided with guide hole cone angle (7), described guide hole cone angle (7) be communicated with guide hole (5) and be communicated with micropore (6).
Further, the diameter of described micropore (6) is 0.25mm ~ 0.45mm.
Further, described thermal insulation medium import (11) and outlet (12) place snap joint is housed.
The utility model beneficial effect is compared with prior art:
The utility model is by controlling medium temperature in the heat preservation channel in spinnerets main body, increasing spinneret orifice draw ratio makes portal temperature and the apparent viscosity of high viscosity spinning melt stablize, waft silk, the adhesion problems of strand at die orifice exit place can be improved, large bunch fiber strand uniform in shaping can be improved; Body due to spinnerets is oval, and during lateral blowing, wind area is large, and outlet tow cooling is even, not easily occurs the breakage phenomena of fiber, effectively can improve Color; The structure of spinneret orifice ensure that melt flows is even simultaneously, and product quality significantly improves; Reinforce with reinforcement between the spinneret orifice of the same area, like this, spinnerets has enough rigidity, to avoid, in process, deformation occurs, ensures at high temperature have enough voltage endurance capabilities; Anti-clogging extruder spinneret plate structure of the present utility model is simple, by arranging the filter screen with filtering function, effectively reducing spinneret orifice blocking, reducing the wire broken rate of product, enhance productivity.
