Description
Technical field
The utility model relates to field of textile machinery, especially a kind of spinning pack preparing high-performance fiber.
Background technology
Superhigh molecular weight polyethylene fibers, owing to having high-strength, Gao Mo, light weight (density ratio water is little), chemically stable, resistance to ultraviolet, endurance, the excellent properties such as wear-resistant, low temperature resistant, with carbon fiber, aramid fiber be called three large high-performance fibers.
Current production superhigh molecular weight polyethylene fibers many employings solution spinning processes, namely polyvinyl resin with super-high molecular weight is in organic solvent swelling, under temperature conditions more than 100 DEG C, dissolve to extrude by double screw extruder and enter into spinning manifold, measuring pump accurate-metering is transported to spinning pack, keep the solution pressure of at least 0.1MPa, finally form dynamic analysis of spinning.Dynamic analysis of spinning finally forms high-performance polyethylene fibres through links such as jet stretch, dry desolventizing, high power hot gas spring.
Links prepared by high-performance polyethylene fibres is all very important, particularly spinning pack extrusion molding process, the blank of direct generation fiber, therefore the mounting means, form, inner structural features etc. of assembly, whole production link and final fiber quality are exerted far reaching influence, needs those skilled in the art more to note.Early stage disclosed patent CN200820135412.6, provides a kind of filature spraying assembly for jelly filatures, needs spinning head framework, interior containing porous plate and spinning head, the circulation hole wall of the porous plate introduced has spiral grooves, increases the frictional force of material and hole inwall, reduces and flows out irregular problem.But porous plate can increase material stream passed resistance in this technical scheme, before causing material to distribute, pressure raises; material is easily piled up before plate, and circulation is poor, and the unit replacement cycle is shorter; and be not easy cleaning, affect production efficiency, be unfavorable for scale application and promote.Patent of invention CN00104380.3, disclose a kind of spinneret assembly for melting spinning and assemble method thereof, spinnerets, filter, top insert are encased in cylindric spinning pack inside, from pushing top insert, filter is out of shape with forcing press again to produce forced sealing power, be arranged on spinning manifold more convenient.First outfit one is needed to place spinnerets in this technical scheme, the cylinder of the spinning packs such as filter, next needs the pressure device being equipped with arrangement, in order to reach sealing effectiveness, finally also need to make separately the annex such as sealing gasket, retaining ring, cost of installation and use is higher.Patent CN201020574174.6 describes a kind of spinneret plate for dry spinning of high-performance polyethylene fibers, the spray silk region of spinnerets is form of annular rings, spinnerets center is solid, be placed with some identical spinneret orifices, each spinneret orifice is by voltage discharging area, the three sections of regions in shrinking zone and constant current district composition, and to define cross section, constant current district be a rectangle.Although the type spinnerets can improve degree of crystallinity and the degree of orientation of fiber, fortifying fibre intensity, but the constant current district that cross section is rectangle causes material interval not flow the hole wall frictional force that is subject to not etc. at this, affect stoste ejection, the problems such as easy generation lousiness, also be not easy to realize high power jet stretch, cause the irregular of fiber.
In sum, in the middle of existing spining technology scheme, some schemes cause component internal pressure high, easy closure plate, and the replacement cycle is short; Some designs are complicated, and use cost is high; Have be arranged on spinning manifold time need to connect by bolt, waste time and energy, at least need two operating personnel cooperation, cost of labor is high, and requires higher to operating personnel's specialized capability, otherwise Rig up error easily produces Lou material problem.Present stage, produce the spinning pack required for high-performance polyethylene fibres, though spinning plate surface mostly is circular or oval, but kit form mostly is square, and adopt bolt pattern and spinning manifold to be connected and fixed, add component internal structure not carry out studying and designing for super high molecular polyethylene solution characteristic, only have the functions such as simple traditional filtration, distribution, ejection, the fiber irregularity obtained is high, quality is low, is difficult to truly realize high-strength, Gao Mo, high performance characteristic.
Given this utility model is proposed.
