Embodiment Construction

[0021] The present invention is used to produce the special-purpose device of coated plastic door and window profile, referring to Fig. A connecting sleeve 1 is provided between the extruder cylinder 10 and the core material die head 11 . Referring to Figure 2, the core material main channel 2 is arranged axially on the connecting sleeve, the left end of the core material main channel communicates with the barrel of the core material extruder; Decreasing, or as shown in Figure 9, the inner diameter is a variable diameter whose middle size is smaller than the two ends. The above structure is convenient for use with extruders of different specifications. A connecting port 4 of the surface material co-extrusion machine is provided along the radial direction of the connecting sleeve.

[0022] See Figure 2, image 3 , Figure 7 , The connecting sleeve is made of left and right half connecting sleeves 3, 5, the left and right half connecting sleeves are processed respectively, and...

Abstract

This invention relates to process cover plastic door and window shape materials device, which belongs to shaping device technique field and comprises core material extrusion machine, core module probe and plane material co-extrusion machine. The invention is characterized by the following: locating a connection cover between the core material extrusion machine and core material module probe; locating core materials main flow and plane co-extrusion at the connection cover; the core main flow left end is connected to core materials extrusion machine cylinder and its right end is connected to the core materials module probes; the ring core materials main flow is located with co-extrusion flow; the plane material co-extrusion flow is connected to the co-extrusion machine through flow guide channel.

Description

technical field [0001] The invention relates to processing equipment for plastic profiles, in particular to a device for processing clad plastic door and window profiles, and belongs to the technical field of plastic processing machinery. Background technique [0002] PVC plastic profile is the preferred material for making doors and windows. Its good sealing, sound insulation, warmth, light weight, corrosion resistance, and no deformation are favored by users. It has developed rapidly in recent years. So far, plastic doors and windows have occupied the entire door and window market. The share of 35% is almost equal to that of aluminum alloy doors and windows, and there is a great momentum of latecomers. But at present, ordinary plastic door and window profiles still have some shortcomings, such as: plastic materials have poor weather resistance, long-term wind and rain and ultraviolet radiation make materials aging; single color affects the overall visual effect of building...
