Detailed description of the invention
As in Fig. 1 ~ 5, a kind of glass Surface of profile film laminating extrusion forming device, comprise pre-shaping device 8, pre-shaping device 8 is connected with the import of the mould 18 with heater, the outlet of mould 18 is provided with extrusion head 12, outside mould 18, be provided with at least one group of coil 9, coil 9 is electrically connected with the control device 10 producing high-frequency alternating current.In this example, have employed three groups of coils, heat each section of mould 18 respectively, in this example, the length of mould 18 is at 0.6-1.2m.Described control device 10 by power frequency supply through rectification, filtering, be reverse into the high-frequency alternating current of 18-20kHz, thus make coil 9 produce high-frequency alternating magnetic field, to make the heating material in mould 18.Preferably, outside coil 9, electromagnetic protection cover 11 is provided with.
Rated power in this example: 7.5Kw; 2.5Kw × 3.Rated voltage: 3 road 380V; Rated frequency: 50Hz; Adopt full-bridge type series resonance; Operating frequency: 18-20kHz; Thermal efficiency utilization rate: >=90%; There is soft start heating/stop mode; There is heater coil short-circuit protection function; There are three and half temperature detection mouths, detected temperatures scope 0-150 DEG C; Inductance value ~ 3 × 110uh.
Preferred structure, as in Fig. 1, is provided with heat-insulation layer 17 between mould 18 and coil 9.The heat-insulation layer arranged does not affect passing through of magnetic field, but can prevent scattering and disappearing of heat, serves the effect reducing energy consumption.
After finished product 13 goes out extrusion head 12, termination is connected with draw-gear 15.Track 14 is provided with below finished product 13.By the traction of draw-gear 15, realize pultrusion operation.
Be provided with glue groove 6 in the import of pre-shaping device 8, above glue groove 6, be provided with rubber roll 5.The glue groove 6 arranged is for being immersed in glue by roving glass fiber 4, and guarantee that glue soaks into roving glass fiber 4, then in extrusion process, glue penetrates into other layers.The resin matrix that glue in this example adopts, is generally unsaturated polyester resin, also has epoxy resin, vinylite, thermosetting methacrylic resin, phenol-formaldehyde resin modified, flame retardant resin etc.Select according to different operating mode.
Heater 7 is provided with in glue groove 6.Glue groove 6 in this example is provided with the bottom of mellow and full projection, and heater 7 is positioned at this projection, and while guaranteeing heating effect, also avoid polluting heater, impurity also can be deposited in groove.
As in Fig. 1, roving glass fiber 4 is by entering pre-shaping device 8 after impregnation in glue groove 6, and on sheet material roller 2, the sheet stock 3 of winding enters pre-shaping device 8 through deflector roll, and on fabric roller 1, the covering 16 of winding, enters pre-shaping device 8 through multiple shaped device.
Described sheet material roller 2 and fabric roller 1 are many groups.For ease of observing, only illustrate one group in FIG.
Covering 16 in this example adopts the PVC material covering being printed with exquisite texture.The difficult point of coated covering 16 is in pultrusion process easily wrinkling, break, and seam crossing is not easily smooth.In the present invention for overcoming this difficult problem, have employed the structure of multiple profiled sheeting or format roll.
As in Fig. 1 ~ 4, described shaped device is multiple profiled sheeting, and described multiple profiled sheetings are provided with forming hole 104, and described forming hole 104 is successively from straight shape transition to the bending shape corresponding to glass section bar outer surface.Structure thus, makes the covering 16 through forming hole 104 progressively be transitioned into the shape corresponding to glass section bar outer surface.As in Fig. 2, progressively covering 16 is bent into round rectangle by forming hole 104, thus guarantees that covering is smooth, and can seam be reduced.In Fig. 3, then progressively covering 16 is bent into circular arc by forming hole 104.By above-mentioned profiled sheeting, then coordinate follow-up pre-shaping device 8 and mould 18, covering 16 is fitted tightly with the sheet stock under it is smooth, improves the appearance of finished product.Have employed the structure of the first profiled sheeting 101, second profiled sheeting 102 and the 3rd profiled sheeting 103 in this example, but according to operating mode, adopt more or less profiled sheeting to be also feasible.Profiled sheeting in this example preferably adopts the material of low-frictional force, such as polytetrafluoroethylene (PTFE).
Preferred scheme is as in Fig. 4, and the position reaching more than 65 degree at the bending angle of the bending part of forming hole 104 is provided with briquetting roller 105.Bending larger position be the crackly position of covering 16, the briquetting roller 105 of setting makes this place become rolling friction by sliding friction, reduces the frictional force at this place, thus avoids covering 16 to break.Structure thus, the present invention can adopt thinner covering 16, and with the surface of glass section bar of better fitting, presentation quality is better.
In preferred scheme, the angle that the shape of described briquetting roller 105 makes covering 16 be bent on briquetting roller 105 surface, is greater than the bending angle of the bending part of forming hole 104.Structure thus, makes the bending angle of covering 16 strengthen, and such as, the position of 90 degree, the bending angle of covering 16 is 92-95 degree, and with in follow-up operation, fit in covering surface that is automatic and glass section bar, thus seam is more smooth.
Another optional scheme is as in Fig. 5, and described shaped device is organize format roll positioned opposite more, and the gap between each composition forming roll is successively from straight shape transition to the bending shape corresponding to glass section bar outer surface.Such as, the first format roll 106, second format roll 107 in Fig. 5 and the 3rd format roll 108.Because format roll exists the difference of linear velocity in rotation, therefore, it is little that format roll is applicable to bending angle, but the occasion that glass Surface of profile shape is comparatively complicated.
The angle having at least the shape of the format roll of a group to make covering 16 to be bent on briquetting roller 105 surface, is greater than the bending angle corresponding to glass section bar outer surface.Structure thus, makes the bending angle of covering 16 strengthen, and such as, the position of 90 degree, the bending angle of covering 16 is 92-95 degree, and with in follow-up operation, fit in covering surface that is automatic and glass section bar, thus seam is more smooth.
With glass sheet stock after roving glass fiber 4 impregnation, such as glass glues and the covering of PVC material, under the pulling force effect of draw-gear 15, be organized into after the shape roughly similar to mould through pre-shaping device 8, entering in metal die is made mold heated to operating temperature by coil 9 by high frequency magnetic field, generally continuous pultrusion process is divided into preheating zone, gelling district and curing area, three coils 9 respectively in this example corresponding, by providing different frequencies, the temperature that this region reaches different also can be made.Resin is in heating process, and temperature raises gradually, and viscosity reduces.Behind preheating zone, resin system starts gelling, solidification, and in curing area, product is heated and continues solidification, has enough curing degrees during to ensure depanning.
The above embodiments are only the preferred technical solution of the present invention; and should not be considered as restriction of the present invention; the technical scheme that protection scope of the present invention should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection scope of the present invention.
