Abstract
The utility model provides a new type polypropylene spunbonded nonwoven fabric double clothes racks type spinning die head and spinning component which belongs to the textile machinery field. The spinning die head and spinning component are core component for improving product quality in polypropylene spunbonded nonwoven fabric production process. A space structure technique 'one is divided into four, four-in-one' by using double clothes racks type flow channel, pressure balance trough, sealing structure between spinning component and spinning die head, diffluence small hole of distribution board and spinneret hole of spinneret, can make melt distributed uniformly, has equilibrium pressure and stabile spinning. The double clothes racks type spinning die head can reduce height size of die head body in condition of ensuring clothes rack flow channel pie slice angle invariability, whole breadth direction melt film is uniform more easily, and filming product quality is increased, material cost is reduced. By using a measuring pump with relatively small flow rate can find matching manufacturer easily, and reduce equipment matching cost at the same time ensuring output and measurement precision. Installing difficulty of spinning component is reduced greatly, sealing is reliable and production cost is reduced.
Description
Affiliated technical field
The utility model belongs to field of textile machinery, particularly relates to the spinning die head and the filament spinning component of polypropylene spunbond non-weaving cloth production equipment.
Background technology
At present, polypropylene spunbond producing technology of non-woven fabrics equipment at wide cut, long slit rotor spinning, drawing-off, lapping, known spinning die head all adopts the unlined garment shelf structure, and the melt that spinning pump is carried into is in spinning die head inner flow passage is assigned to 3.2 meters or wideer fabric width scope.Find that in development process there are some defectives in wide cut unlined garment frame type spinning die head, is embodied in:
1, load two ends in film chamber are variant with the centre, the spinning instability, and the two ends strand breaks end easily.
2, strand becomes net back cloth cover zonal thickness road phenomenon to occur, and product quality (mainly being uniformity index) is not ideal.
3, measuring pump type selecting difficulty domesticly can not find supporting producer.The measuring pump of low discharge runs up influences measuring accuracy; The measuring pump processing and manufacturing difficulty of big flow.
4, the filament spinning component hermetically-sealed construction is unreliable, occurs melt easily and leaks the material phenomenon, has increased the equipment use cost.
Summary of the invention
For overcoming existing defective, the utility model provides a kind of pair of clothes hanger type spinning die head and filament spinning component.This equipment not only can improve the quality of products, and can also reduce coordinative composition of equipments cost and equipment use cost.
The technical scheme that its technical problem that solves the utility model adopts is:
Fluid division or fluid overlapping phenomenon that the utility model spinning die head might occur for solving two runner connections, adopt two clothes hanger type flow passage structures, use two measuring pumps than low discharge (150CC/R), side symmetric position at the spinning die head has two charging apertures, the melt that enters through the measuring pump accurate measurement from two charging holes distributes in two separate fan sections, the bottom in fan section be communicated with and be provided with a relief groove, the below is the voltage stabilizing district again, and below, voltage stabilizing district is a filament spinning component.Under the certain prerequisite of exit width size, the advantage of two clothes hanger type runners is: one, melt import and export path is short, and the pressure loss is little; Two, the melt discrete areas is that the fan section angle diminishes, and helps more guaranteeing that outlet pressure is even, the flow unanimity.
Adopt the polytetrafluoroethylene wire hermetically-sealed construction between the utility model filament spinning component and the spinning die head, installation faying face (upper and lower faces) at distribution plate is provided with the semicircular seal groove of a whole circle, circular teflon seal bar is embedded in the seal groove, by the thrust of bolt and the heat expansion distortion of tetrafluoroethylene sealing strip filament spinning component and die head is closely combined together.
The utility model melt is all pressed and uniform distribution except that adopting conventional multiple layer metal silk screen pack and suitable angle of flare, but also arranged meticulously in nearly 17000 orifice flow zones of shunting apertures of distribution plate and spinnerets.The shunting aperture of distribution plate and the spinneret orifice melt of spinnerets distribute and adopt " unification in a minute four, four " space structure, promptly the paths such as melt of flowing out of each aperture on the distribution plate, etc. angle of flare distribute to four spinneret orifices; And each spinneret orifice on the spinnerets is accepted four melts that aperture flows out on the distribution plate simultaneously.
The beneficial effects of the utility model are:
1, two clothes hanger type spinning die heads are at the height dimension that guarantees can reduce under the constant situation of clothes hanger runner fan section angle die head, and the easier uniformity of whole fabric width direction melt films has reduced material cost when having improved the film-forming products quality.
2, flow through that the melt import and export pressure of each spinneret orifice falls and flow is in full accord, the wire vent situation is in full accord.Spinning is stable, has improved the spun-bonded non-woven fabrics product quality.
3, adopt relatively than the measuring pump of low discharge, find supporting producer easilier.When guaranteeing output, measuring accuracy, reduced the coordinative composition of equipments cost.
4, the filament spinning component installation difficulty reduces greatly.During actual the use, the discharge of need releasing before filament spinning component is installed, die head is in 230 ℃～250 ℃ conditions of high temperature, and filament spinning component then is the normal temperature state, and the reason of heat expansion, shrinkage causes traditional tenon groove structure sealing unreliable.Adopt structure shown in Figure 4, eliminated the hidden danger that the filament spinning component screen pack is damaged because of installation process, sealing is reliable, has reduced the production use cost.
