Synthetic-resin window sectional materials with multiple-color and three-dimensional surface figure and producing apparatus thereof

[0034] Such as Figure 4 As shown, the synthetic resin window profile production equipment with multi-color and three-dimensional surface provided by the present invention mainly includes an extruder 1 capable of melting and extruding resin raw materials; the resin extruded by the extruder 1 is extruded to have A mold 2 for extruding resin 3 with a certain shape; a vacuum cooling device 4 that can cool and set the extruded resin 3 with a certain shape extruded from the mold 2; connected to the mold 2 to melt resin raw materials of other materials And an auxiliary extruder 9 which is extruded and supplied to the die 2; and an embossing device 200 which is arranged inside the die 2 and can emboss a pattern on the surface of the extruded resin 3 extruded by the die 2.

[0035] Such as Figure 5 As shown, the mold 2 is provided with a molten resin inflow channel 12 that allows the resin melted by the auxiliary extruder 9 to flow into it, and the resin melted by the auxiliary extruder 9 is evenly distributed in the slave extruder. 1 and the dispersed flow channel 13 on the surface of the extruded resin 3 extruded by the die 2, and the resin flowing in from the dispersed flow channel 13 has a different color from the extruded resin 3, thereby forming a double extrusion structure.

[0036] As shown in Figure 6a, Figure 6b and Figure 6c As shown, the embossing device 200 is arranged inside the mold 2, which includes a pattern roller 200a installed on the mold 2 near the upper end of the vacuum cooling device 4; horizontal adjustment devices 200c and 200c arranged on the left and right sides of the pattern roller 200a. The height adjustment device 11; and an elastic device installed inside the height adjustment device 11 and the level adjustment device 200c, which can apply pressure to the pattern roller 200a so that it can press out patterns on the surface of the extruded resin 3. The adjusting screw on the height adjusting device 11 can be used to adjust the depth of the pattern on the surface of the synthetic resin window profile. In addition, the installation position of the pattern roller 200a on the mold 2 is provided with a circular pattern roller insertion hole 200b. The pattern template provided on the surface of the pattern roller 200a may be a relief plate or an intaglio plate, but in order to avoid contamination of the surface of the extruded resin 3, an intaglio plate is preferably used. In addition, the driving of the pattern roller 200a is mainly driven by an unpowered drive by the outflow force of the synthetic resin, and an electric drive method may also be adopted, but it is better to adopt an unpowered drive method in consideration of simplifying the device. When producing, first melt the synthetic resin raw material in the extruder 1, and extrude the melted synthetic resin into the mold 2 where the resin base is installed, and at the same time, the other materials melted in the auxiliary extruder 9 The synthetic resin is extruded to the surface of the synthetic resin extruded by the extruder 1 through the molten resin inflow channel 12 and the dispersion flow channel 13 on the mold 2, and then the pattern roller 200a on which the pattern template is mounted on the surface is subjected to double extrusion. The surface of the extruded synthetic resin is embossed with patterns to form the extruded resin 3. After that, the extruded resin 3 with uneven patterns on the surface passes through the vacuum cooling device 4 and then is cooled and shaped into a profile 3a of a desired shape. Finally, a cutting machine 6 is used to cut the profile 3a pulled out by the demolding device 5 into a certain length and send it to the stage 7. Since the subsequent procedures of the equipment are the same as those in the prior art, the production of ordinary synthetic resin window profiles can also be carried out after the auxiliary extruder 9, the pattern roller 200a and other devices are disassembled. Since the surface of the profile 3a produced by the synthetic resin window profile production equipment with multi-color and three-dimensional surface provided by the present invention is formed of a resin of a different material from that of the extruder 1, the surface can have different colors, and the The resin also contains durable acrylonitrile-acrylate-styrene and polymethyl methacrylate, which can ensure that the surface of the profile 3a on the outdoor side has better durability, and therefore can extend the service life of the window. In addition, because the embossing device 200 is installed inside the mold 2, the pattern can be extruded before the surface of the extruded resin 3 is cooled and shaped, so that the extruded pattern can be more obvious, and it is different from the prior art in the mold 2. Compared with the need to install other embossing devices between the vacuum cooling device 4, it can greatly save space, and only need to install or remove the embossing device 200 to realize the conversion between double extrusion molding and single extrusion molding, so it can be greatly shortened. Conversion time. In addition, such as Figure 7 As shown, various pattern rollers 200a can be used to produce profiles 3a with different concave and convex patterns, so as to make its appearance more beautiful. And from image 3 with Figure 8 It can be seen that the prior art synthetic resin window profile 3b is significantly different from the synthetic resin window profile 3a provided by the present invention with a multi-color and three-dimensional surface.
