By utilizing co-extrusion pressure to form epidermal area, various material can be utilized to provide shades of colour for epidermal area.Because the material different from section bar is formed by with section bar by co-extrusion pressure, so do not need the post processing being similar to attachment sheet material after section bar is produced.And, can manufacturing cost be reduced and also strengthen the machinability of product.In addition, owing to not using adhesive, co-extrusion pressure is environmental protection and is beneficial to overcome cut problem.
According to the present invention, the co-extrusion resin composition forming epidermal area S comprises lumber fibre, thus improves the natural grain of wood and therefore improve its pattern.
Co-extrusion resin composition comprises the first raw material for the formation of primary colours, the second raw material for the formation of semi-tone color and the 3rd raw material for the formation of high tonal color.
In the present invention, based on, first of material the raw-material feature comprises lumber fibre to make the epidermal area of section bar have the natural grain of wood.First raw material comprise 70%PVC, 10-15% coal stone, 15-20% lumber fibre, a small amount of inorganic pigment with excellent weatherability, a small amount of weatherability additive etc.
The second raw material for the formation of semi-tone color comprise PVC, ASA, PMMA and PE resin of the high polymeric with the fusing point higher than the first raw material (basic material), have a small amount of additive etc. of a small amount of inorganic semi-tone pigment, the such as lubricant of excellent weatherability.
The 3rd raw material for the formation of high tonal color comprise PVC, ASA, PMMA and PE resin of this high polymeric with the fusing point higher than the first raw material (basic material), have a small amount of additive etc. of a small amount of inorganic high tone pigment, the such as lubricant of excellent weatherability.
According to the present invention, in order to form a kind of color, the first raw material, the second raw material and the 3rd raw material do not mix.But be formed in the state on section bar at epidermal area under, second raw material and the 3rd raw material respectively based on material the first raw material on show semi-tone color and high tonal color, often kind of color can be distinguished mutually, thus the natural color with excellent graphic is provided.
In order to make the color of resin composition mutually distinguish, the first raw material have the fusing point of about 160 ° to 165 °, and the second raw material have the fusing point of about 175 ° to 185 °, and the 3rd raw material have the fusing point of about 175 ° to 185 °.
Auxiliary co-extrusion pressure equipment 100 is for heating co-extrusion resin composition and pressurizeing to this co-extrusion resin composition towards co-extrusion pressure mould 30b subsequently.If the fusing point of resin composition is all identical, then all resin compositions all melt and mix in auxiliary co-extrusion pressure equipment 100, and therefore often kind of color is not mutually distinguished but becomes a kind of color.Thus, in order to prevent this phenomenon, each fusing point is mutually different.In other words, when the inside of auxiliary co-extrusion pressure equipment 100 is heated to about 160 ° to 180 °, first the basic material with minimum fusing point is fused into gel state, and the second raw material and the 3rd raw material partly melt and are discharged to co-extrusion pressure mould subsequently.In this process, second raw material with semi-tone color and the 3rd raw material with high tonal color form nature pattern on basic material.
And co-extrusion resin composition can also comprise negative ion powder, air freshener etc. to room anion, thus the environment of similar forest is provided or gives out the natural fragrance of similar plants bacteriocidin smell.
Fig. 5 is the perspective view according to knurling rolls 50 of the present invention, and Fig. 6 a and Fig. 6 b is cross-sectional view according to knurling rolls 50 of the present invention and enlarged drawing.
Knurling rolls 50 of the present invention have the diameter larger than the knurling rolls of routine and pattern is formed two rank to provide excellent pattern continuity, thus strengthen exterior design and dimension sense.Knurling rolls 50 are rotatably installed in rotating shaft 51 place, and form uniform pattern on its surface.That is, as shown in Figure 6 a, the surface of knurling rolls 50 defines two rank uniform pattern.In other words, knurling rolls 50 comprise and are formed as the first relatively large projection 53 and in the first projection 53, are formed as the second relatively little projection 55.First projection 53 and the second projection 55 are not even and the shape of rule but arbitrary shape (the conventional knurling rolls shown in Fig. 7 a and Fig. 7 b have only with the simple pattern that uniform depth is arranged, and therefore its pattern is deteriorated).The degree of depth D of the first projection 53 is formed as darker than the degree of depth of the projection formed on conventional knurling rolls, thus increases the pattern of pattern.
Knurling rolls 50 of the present invention have large diameter RD and large projection.If increase the diameter of knurling rolls, then the circumferential lengths on knurling rolls surface also increases, and the length of the embossed pattern formed along Surface of profile.Thus, the repetition period of the pattern that section bar is formed tails off, thus strengthens the pattern of pattern.
But the diameter being arranged in the knurling rolls 50 between mould 30 and calibrator 70 is restricted due to the restriction in the space between above-mentioned mould 30 and calibrator 70.For solving this problem, the present invention proposes the new shape shown in Fig. 8 and Fig. 9.
Fig. 8 shows the part according to the co-extrusion pressure equipment for the manufacture of window frame profile of the present invention seen in the direction different from Fig. 2, wherein eliminates auxiliary co-extrusion pressure equipment, and Fig. 9 is the mould 30 of Fig. 8 and the cross-sectional view of knurling rolls 50.
With reference to figure 8 and Fig. 9, in the space G between mould 30 and calibrator 70, lower space G1 is less, but upper space G2 is comparatively large to install knurling rolls 50.And the surface being furnished with knurling rolls 50 of mould 30 by sphering to have recess 35, and therefore, it is possible to provide the sufficient space can installed and there are large diameter knurling rolls 50.That is, the curved portion 35 corresponding with the periphery of knurling rolls 50 is formed in the surface of mould 30, and section bar P is discharged to described surface.Therefore, even if the diameter RD of knurling rolls 50 becomes larger than the diameter of conventional knurling rolls, still when there is no the space between excessive increase mould and calibrator, knurling rolls 50 can be installed.Although semi-circular recesses part shown in the drawings, the invention is not restricted to this shape, and if necessary, the recess of various shape can be provided, such as, there is the circular shape of 90 degree of central angles.
With reference to figure 8, calibrator 70,80 can comprise dry-calibrating device 70 and wet type calibrator (watercalibrator) 80, or one of them.And, in cooling device 90, in water pot, on the direct of travel of section bar, arrange multiple hollow pan 93, such that the section bar through pan can be cooled and profile shapes does not change.
Figure 10 illustrates according to one of pan of cooling device 90 of the present invention.It is that the section bar P that makes of hollow can through wherein that pan 93 is formed as heart part place wherein, and roller 95 is arranged in the top of the hollow space of pan 93.The rotating shaft of roller 95 is fixed to the top of pan 93, and roller 95 rotates while contacting with the section bar passed wherein.Epidermal area S is formed in the upper surface of section bar P by co-extrusion pressure, and embossed pattern is formed thereon by knurling rolls 50.
In conventional chilling device, because do not have roller 95 of the present invention, so the upper surface of the hollow bulb of pan contacts with through section bar wherein, and as a result, the embossed pattern be formed on the upper surface of section bar may be destroyed.
According to the present invention, because be provided with the rotatable roller contacted with section bar upper surface at the correct position of pan, contact with the conventional surface of section bar the linear contact lay changed into it, and therefore prevent the embossed pattern be formed on section bar upper surface to be destroyed.
In the present invention, as shown in Figure 3, auxiliary co-extrusion pressure equipment 100 is utilized by epidermal area co-extrusion pressure on section bar upper surface.And the auxiliary co-extrusion pressure equipment 100 with the path of improvement provides by improving conventional auxiliary co-extrusion pressure equipment, and this routine assists co-extrusion pressure equipment in conventional manufacturing equipment for co-extrusion pressure PVC or other material.
In auxiliary co-extrusion pressure equipment 100 of the present invention, co-extrusion resin composition utilizes predetermined and constant exert pressure and is supplied to the top of co-extrusion pressure mould 30b, makes on the surface of section bar P, form epidermal area S.As shown in drawings, co-extrusion resin composition, by horizontal feed, rotates about 90 degree, is again vertically carried to introduce the top of co-extrusion pressure mould 30b subsequently.Connector 110 is for changing into vertical direction by the direction of motion of co-extrusion resin composition.Figure 11 is the cross-sectional view according to connector 110 of the present invention.Connector 110 is formed with the ingate 111 of introducing co-extrusion resin composition, the outlet opening 112 turned to vertically relative to ingate 111 and changes the sweep 113,114 of direct of travel.The internal diameter of connector 110 narrows from ingate 111 towards outlet opening 112, and the transporting velocity of resin composition and pressure are increased.Sweep 113,114 allows direct of travel to change into vertical direction smoothly from horizontal direction.
Figure 12 is the cross-sectional view of ordinary connector.Wherein, the direct of travel of material is carried to change into vertical direction sharp from horizontal direction.Therefore, the material carried in the horizontal direction and vertical wall collide and therefore return or accumulate near vertical wall, there is the problem that discharge pressure increases accordingly.But, because the invention provides sweep, so material direct of travel can change smoothly.
Figure 13 illustrates the comparison example being formed pattern by co-extrusion pressure equipment on section bar, and Figure 14 illustrates and on section bar, forms pattern by co-extrusion pressure equipment according to the present invention.
Co-extrusion resin composition is incorporated into the top of mould 30 from auxiliary co-extrusion pressure equipment 100, and introduces the co-extrusion pressure pressurization space 38 formed in a mold subsequently.Then, co-extrusion resin composition is applied to through mould and by the upper surface of the section bar P of horizontal feed or upper surface and side surface, thus forms the epidermal area S of section bar.Wherein, the second raw material of resin composition and the 3rd raw material form nature pattern.
But, as shown in figure 13, if co-extrusion pressure pressurization space 38 is formed as single space, then pressure is concentrically applied the core of the resin composition be coated on section bar P, and therefore intensively form whirlwind pattern S1 at the core of section bar upper surface, thus provide artificial sensation.
In the present invention, for solving this problem, co-extrusion pressure pressurization space 38 is formed as multiple compartment.For this reason, the invention provides the path guiding piece 39 be formed in co-extrusion pressure pressurization space 38, resin composition to be directed to point other space.Then, to pressurize in auxiliary co-extrusion pressure equipment 100 and the resin composition be introduced in the co-extrusion pressure pressurization space 38 of mould is directed into point other space, and therefore prevent resin composition to be concentrically applied the core of section bar upper surface.Thus, the pattern S2 be formed on the epidermal area S of section bar is formed uniformly on the upper surface of section bar, thus has been formed uniformly the natural pattern being formed as bar shape.
As shown in figure 14, because be formed at the pattern S2 that the epidermal area S of the section bar P manufactured in co-extrusion pressure equipment of the present invention is formed by suitably distributing the second raw material and the 3rd raw material via path guiding piece 39, so it has natural and irregular pattern and therefore has high pattern.
