Description
Technical field
The present invention relates to a kind of production line, relate in particular to a kind of high-performance sound-absorbing insulation material production line.
Background technology
Existing YDB sound-absorbing insulation material is many to be made up of polyster fibre and polypropylene fibre superfine fibre, and spunbond cloth is covered on the surface or aluminium foil is handled, and during fabrication, generally all takes to blow polyster fibre and polypropylene fibre superfine fibre finished product, carries out the surface again and covers spunbond cloth or aluminium foil processing.Technology is made completion respectively at many production lines or a plurality of producer; The cellucotton finished product is influenced by environment, storage, humidity etc. through repeatedly circulation, its fluffy structure and insulating properties are destroyed; Influence the sound-absorption and heat-insulation quality, it is higher to cover the sticking cost of handling and circulating simultaneously.
The YDB sound-absorbing insulation material that is applied to high-grade automobile at present only has the U.S. and several families of manufacturer of Germany can realize accomplishing with the bar production line.Integrate and intermediate controlled specification requirement height because of its relevant device, its technology is monopolized by them.It also mainly is dependence on import at present that the domestic market is supplied with.
Summary of the invention
The technical problem that the present invention will solve provides a kind of technological transformation that melts and sprays, fills, makes etc. key processing equipment through integration; Set up high-performance sound-absorbing insulation material production line, product melt and spray, fill, make the high-performance sound-absorbing insulation material production line that operation is accomplished in same production line.
In order to address the above problem, the present invention realizes through following technical scheme:
High-performance sound-absorbing insulation material production line of the present invention comprises mainframe, and the top of mainframe is provided with extruding machine; Be provided with round roller lapper in the mainframe, the top of circle roller lapper be provided with link together melt and spray manifold, measuring pump and filter, melt and spray manifold and be connected with extruding machine; The sidepiece of circle roller lapper is provided with the wind heater; The sidepiece of wind heater is provided with air-introduced machine and air blast, and the wind heater is through pipeline connection centrifugal induced draught fan and air blast, and the sidepiece of mainframe is provided with round dot hot roll and cutting machine; Melt and spray the manifold below and be provided with spinning head and spinning micropore, micro-pore diameter is 0.3-0.4mm.
The present invention melts and sprays, fills, makes etc. the technological transformation of key equipment through integration; The high-performance sound-absorbing insulation material production line of building; Absorbing advanced superfine fibre and multicomponent spinning technology; Through studying the improvement that thin distribution plate forms polymer distribution path and spinneret orifice, further improve the design of air knife, make the fiber of extruding through die head carry out evenly, effectively stretch; Inner due micropore and uniform gap distribution behind the increase forming materials, thus reach the good sound absorption effect of heat insulation.
Compared with prior art; The invention has the beneficial effects as follows: 1, the present invention melts and sprays, fills, makes etc. the technological transformation of key processing equipment through integration; Set up high-performance sound-absorbing insulation material production line, the operation that melts and sprays, fills, makes of product is accomplished in same production line.2, form the improvement of polymer distribution path and spinneret orifice through thin distribution plate; Further improve the design of air knife; Make the fiber of extruding through die head carry out evenly, effectively stretch; Inner due micropore and uniform gap distribution behind the increase forming materials, thus reach the good sound absorption effect of heat insulation.3, the present invention adopts a corner cut and a two-sided net-forming technology that receives, and fiber does not have and splashes and reaction force, becomes net efficient to improve 0.75-1 doubly than a method that vertically receives of plain net.
Description of drawings
Fig. 1 is the structure chart of high-performance sound-absorbing insulation material production line of the present invention.
Fig. 2 melts and sprays manifold member sketch.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
As shown in Figure 1, a kind of high-performance sound-absorbing insulation material production line comprises mainframe; The top of mainframe is provided with extruding machine 1, is provided with round roller lapper 5 in the mainframe, the top of circle roller lapper 5 be provided with link together melt and spray manifold 4, measuring pump 3 and filter 2; Melt and spray manifold 4 and be connected with extruding machine 1, the sidepiece of circle roller lapper 5 is provided with wind heater 8, and the sidepiece of wind heater 8 is provided with air-introduced machine 9 and air blast 10; Wind heater 8 is through pipeline connection centrifugal induced draught fan 9 and air blast 10; The sidepiece of mainframe is provided with round dot hot roll 6 and cutting machine 7, melts and sprays manifold 4 belows and is provided with spinning head and spinning micropore, and micro-pore diameter is 0.3-0.4mm.
As shown in Figure 2; Melting and spraying manifold 4 comprises and melts and sprays assembly 41, air knife 42 and air cavity 43, and melt and spray manifold 4 belows and be provided with spinning head and spinning micropore, micro-pore diameter is 0.3-0.4mm; Be far longer than conventional melt spinning for more helping its draw ratio of spinning moulding, be 10-15.Form special air cavity simultaneously between ejection assemblies and the air knife, the high-pressure hot wind air communication is crossed the air cavity slit and is sprayed with the speed that is similar to velocity of sound, the most advanced and sophisticated spinning awl that forms of air knife blade and spinning pack.Melt sprays from the spinning micropore, by high velocity air clamping, traction, drawing-down, forms superfine fibre through the crosswind cooling at spinning awl place.
Melting and spraying manifold 4 is key equipments in the production line, the quality of manifold directly have influence on whole production line whether success of driving, whether whether good, the quality that spins the silk that comes of monomer fiber finer, feel good etc. to spin the silk that comes.
Cylinder adopts a corner cut and a two-sided net-forming technology that receives, and it is cotton that fiber adopts the air-flow of about 12 meter per seconds to be blown in system, for fiber accumulations provides reliable polymerizing energy, reaches the beneficial effect that increases the finished product sectional density.Simultaneously, project adopts a corner cut and a two-sided net-forming technology that receives, and fiber does not have and splashes and reaction force, becomes net efficient to improve 0.75-1 doubly than a method that vertically receives of plain net, the operation energy consume and occupation area of equipment less.
Its operation principle is following:
Raw material is sent into the melt distribution cavity through the accurate measurement of measuring pump behind extrusion molten, through getting into spinning manifold after the rectification, be emitted into silk through the spinning micropore again, under the injection of high speed hot-air flow stretches, obtains superfine fibre.The key that influences into yarn quality is that the uniformity along the air flow jetting speed of fabric width direction is consistent with the flow velocity of melt distribution cavity, flow equates, pressure distribution is even.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
