Fig. 1 is that monofilament that the utility model embodiment provides spins and leads the association system schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Monofilament of the present utility model spins and leads association system and spin based on existing monofilament and lead association system, comprises the melt extruded equipment, water-bath cooling device, pulling equipment, steam-heating apparatus and the winding apparatus that are connected successively.
Melt extruded equipment adopts horizontal screw extruder 1, and screw rod is selected φ 65mm for use, and screw rod adopts sectional type screw pin, draw ratio to adopt L/D35,5 thermals treatment zone, and the physical property of assurance high-viscosity melt plays an important role to becoming yarn quality.Screw extruder 1 mainly drags speed-adjusting and control system by alternating current generator, decelerator, screw rod, sleeve, heating and temperature control system and forms.Thick dawn polyethylene (HDPE) enters in the extruder from the screw feed mouth, and each is distinguished under heating and the screw rod rotation extruding at screw rod, and the section of solid is melted and is squeezed into melt, and sets up certain pressure at head and use for measuring pump following current injection.Extruder adopts horizontal type structure, and the AC induction motor frequency control drags decelerator by V belt, rotates through decelerator secondary gear deceleration rear drive screw rod.It is unimpeded to guarantee the section conveying to be provided with the cooling zone at charging aperture, prevents the HDPE bonding.Heating temperature-control system has temperature and sets, controls and Presentation Function.Drag speed-adjusting and control system and adopt the pressure closed loop speed-regulating control device, be provided with the warning of pressure bound, parking, screw speed hypervelocity parking (super setting 15%) and the overtemperature degree upper limit and stop functions such as heating.The spinning temperature high density polyethylene (HDPE) is as a kind of comparatively traditional thermoplastic, possessed the comparatively ripe temperature control technological parameter that melt extrudes, and head temperature generally is controlled at 240 ℃ to 280 ℃.
For improving melt quality, prolonging the assembly life cycle, the utility model is provided with the fusant filtering equipment that is made of fondant filter 2 behind the melt extrusion equipment.Melt not only can fall contaminant filter in fondant filter 2, and melt is played a part to stir and homogenising polymer, improves melt quality and prolongs the assembly life cycle.The filter element of fondant filter 2 is the candle wick formula, by biphenyl vapour phase heat tracing.Fondant filter 2 front and back are provided with the melt pressure sensor, according to pressure reduction before and after the prefilter, judge whether to carry out filter core and switch.The filter core of fondant filter can be changed under non-stop-machine situation.Filter medium blocks and must switch when the pressure reduction 6-8MPa of front and back, and filter back pressure sensor also plays the control lever rotating speed, guarantees the stable effect of melt pressure.Two Room about filter is provided with, filter element are the candle wick formula, the optional 7-19 core of filter area, optional 15 μ m to the 40 μ m of filtering accuracy, by biphenyl vapour phase heat tracing, the melt import and export is provided with pressure-measuring-point, with control extrusion pressure and relatively prefilter pressure at two ends variation.Fondant filter 2 can be selected horizontal fondant filter and vertical fondant filter for use.Vertical fondant filter profile is bigger, complicated operation, but self capacity is big, and variations in temperature is little, no dead point.
After fusant filtering equipment, be provided with the spinning measuring equipment that constitutes by measuring pump 3.The main effect of measuring pump 3 is accurate measurements, evenly and continuously carries spinning solution.Measuring pump 3 basic structures are by three blocks of pump plates, two straight spur gears that the intermeshing number of teeth is identical, and driving shaft, driven axle, shaft coupling is formed.Measuring pump adopts external gear rotary pump usually, utilizes driving gear and driven gear between cog and outer cover plate, and the confined cavity that inner cover plate and intermediate plate form is sent to outlet to spinning solution from inlet.
Increasing measuring pump 3 can be that direct effect is the accurate measurement of spinning solution for spinning technique brings, quantitatively toward the spinning pack convey materials.Thereby guarantee that the spinning fiber number is even.
After measuring equipment, be provided with spinning equipment.Spinning equipment comprises manifold 4 and filament spinning component 5.
HDPE enters manifold 4 by the melt distribution circuit.The HDPE of fusing guarantees that by a special pipeline distribution network melt is transported to each spinning part, no dead angle with the holdup time that equates in manifold 4.Because industry silk viscosity is big, back-pressure is big, the tube wall of pipeline is thicker, to bear bigger pressure.Manifold 4 is by the heating collar heating, and temperature-controlled precision is ± 1 ℃.
Filament spinning component 5 and spinnerets are circular, adopt the circular dress formula high pressure of going up from sealing assembly, high pressure resistantly do not leak.Many to thick dawn HDPE silk radical, the melt amount is big, cooling effect is better.The spinnerets diameter adopts Φ 190mm., when the spinnerets temperature reaches 200 ℃, can spray silk comparatively uniformly, but the surface ratio of ejection silk is more crude.When spinnerets temperature during at 240 ℃, but the ejection silk evenly, a smooth surface. and drawdown is preferably arranged.
The strand of being made by spinning equipment is come out by spinnerets, need enter the water-bath cooling bath and carry out cooling curing.The utility model is provided with the water-bath cooling device behind spinning equipment.Water bath 6 solution temperatures that constitute the water-bath cooling device are controlled between 65 ℃～95 ℃.Strand through the water-bath cooling passes through oiling device again, oils to tow, increases the cohesive force of fiber, improves the antistatic property of fiber, reduces the break-in power between fiber and equipment, fiber and the fiber.
Behind the water-bath cooling device, be provided with steam-heating apparatus and pulling equipment.In order to guarantee fibroin traction and qualitative effect, adopt the multistage mode of traction of multistage heating usually.Be provided with two-stage heating and three-stage traction in the present embodiment, behind cooling device, set gradually first hauling machine 7, the first heating steam case 8, second hauling machine 9, the second heating steam case 10 and the 3rd hauling machine 11.Hauling machine adopts guide wheel and pectination type to divide silk, and 180 monofilament are tiled on the five-roller traction machine, after the first Steam Heating case, 8 HEAT SETTING, enters second hauling machine 9 again and the second Steam Heating case 10 carries out the secondary drawing and heat-setting.Add the 3rd hauling machine 11 at the rear of the second Steam Heating case 10, the reverse resilience of endless tow after preventing to stretch fully is in relaxed state after endless tow is stretched, so that tensile stress is eliminated.
Spin at monofilament of the present utility model and to lead association system and be provided with winding apparatus up-coiler 12 at last, be used for that spinning is wound into roller to finished product.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
