The connectors are injection-molded two-part structures with grooves on the inner side, each containing an O-ring. The inner diameter of the connector matches the outer diameter of the alloy profiled pipe. Flanges are located around the outer perimeter of the two-part structures, with pre-drilled locking holes on the flange faces. Reinforcing ribs are present on the outer sides of the flanges, and the bottom of the flanges and the reinforcing ribs are connected to the plane of the alloy profiled pipe. The production equipment includes an extruder, mold, vacuum cooling box, traction machine, pipe cutter, and support frame arranged sequentially. The integrally formed alloy profiled pipes offer increased strength with the same material usage. The connector structure facilitates installation and provides high sealing performance.

Description

Technical Field

[0001] This invention relates to the technical field of pipes, specifically to an alloy profiled pipe system using multi-layer co-extruded polymer composite and its production equipment. Background Technology

[0002] The original plastic shaped pipes were all formed by welding after multiple bends of sheet metal, and were not a one-piece molded structure. As a result, there would be a longitudinally extending seam. This seam is the weak point of the pipe, and it will break when the pipe is subjected to external force.

[0003] A piping system is formed by connecting individual plastic profiled pipes end to end. Currently, the connection between individual plastic profiled pipes is usually achieved by electrofusion. However, when manufacturing large-diameter plastic profiled pipes, if the pipe wall thickness is thin, the pipe wall is often melted through, resulting in a loose connection. Furthermore, this method of connection structure also results in a relatively weak point at the connection point. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide an alloy profiled pipe system and its production equipment that employs multi-layer co-extruded polymer composites. The alloy profiled pipe has an integrally formed structure, the connection structure of the alloy profiled pipe system employing multi-layer co-extruded polymer composites is reliable, and the production equipment is simple and convenient to operate.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multi-layer co-extruded polymer composite alloy profiled pipe system, comprising alloy profiled pipe and connectors, wherein the alloy profiled pipe is an integrally formed rectangular or square structure, the outer wall of the alloy profiled pipe is longitudinally wavy or straight, and its wall thickness is uniform; the connector is an injection-molded two-slot structure with a groove on the inner side, in which an O-ring is inlaid, the inner diameter of the connector is consistent with the outer diameter of the alloy profiled pipe, the two slots are equipped with flanges on their outer sides, the flange end faces have pre-made locking mounting holes, the outer side of the flange is equipped with reinforcing ribs, and the bottom of the flange and the reinforcing ribs are connected to the plane of the alloy profiled pipe.

[0006] The alloy profiled pipe system of the present invention, which adopts multi-layer co-extruded polymer composite, is further configured such that the connectors are divided into straight connectors and elbow connectors according to different applications.

[0007] The alloy profiled pipe system of the present invention, which adopts multi-layer co-extruded polymer composite, is further configured such that when the outer wall of the alloy profiled pipe is longitudinally wavy, the four side walls of the alloy profiled pipe have a wavy structure.

[0008] The alloy profiled pipe system of the present invention, which adopts multi-layer co-extruded polymer composite, is further configured such that the alloy profiled pipe is integrally formed by multi-layer co-extruded polymer composite.

[0009] The alloy profiled pipe system of the present invention, which adopts multi-layer co-extruded polymer composite, is further configured such that the wall thickness of the alloy profiled pipe is 3~20mm.

[0010] The production equipment for the multi-layer co-extruded polymer composite alloy profiled pipe system includes an extruder, a die, a vacuum cooling box, a traction machine, a pipe cutter, and a support frame arranged in sequence. The raw material extruded by the extruder is conveyed to the die, and the pipe extruded from the die is a pipe with a circular cross-section. The vacuum cooling box is equipped with a profiled forming die, and the circular pipe is fitted outside the forming die. After being shaped by the negative pressure in the vacuum cooling box, it is formed into a profiled pipe and connected to the traction machine.

The alloy profiled pipe 1 is an integrally formed rectangular or square structure, and is integrally formed by multi-layer co-extruded polymer composite. The outer wall of the alloy profiled pipe 1 is longitudinally corrugated or straight, and its wall thickness is uniform. Figure 3 This is a schematic diagram of the alloy profiled tube 1 with a longitudinally wavy outer wall. When the outer wall of the alloy profiled tube 1 is longitudinally wavy, the four side walls of the alloy profiled tube 1 have a wavy structure, and the wall thickness of the alloy profiled tube 1 is 3~20mm; Figures 4 to 7 As shown, the connector 2 is an injection-molded two-slot structure with a groove on the inner side. An O-ring is inserted into the groove. The inner diameter of the connector 2 is the same as the outer diameter of the alloy profiled pipe 1. The two slots are equipped with flanges 3 on their outer sides. The flanges 3 have pre-made locking holes 4 on their end faces and reinforcing ribs on their outer sides. The bottom of the flanges 3 and the reinforcing ribs are connected to the plane of the alloy profiled pipe 1. After the connector 2 is fitted onto both ends of the fixed-length alloy profiled pipe 1, the pre-made locking holes 4 are aligned with the fastening screws to form a sealed alloy profiled pipe system using multi-layer co-extruded polymer composite.

[0025] Depending on the application, the connector 2 is divided into a straight connector 2 and an elbow connector 2. The structure of the straight connector 2 is as follows: Figure 4 and Figure 5 As shown. The structure of the elbow connector 2 is as follows: Figure 6 and Figure 7 As shown.

The raw material extruded by the extruder 5 is conveyed to the die 6, and the pipe extruded from the die 6 is a pipe with a circular cross-section. The vacuum cooling box 7 is equipped with a profiled forming die, and the circular pipe is fitted outside the forming die. After being shaped by the negative pressure in the vacuum cooling box 7, it is formed into a profiled pipe and connected to the traction machine 8. After being cut by the pipe cutter 9, it is conveyed to the support frame 10.

[0027] The number of extruders 5 is two, and the raw materials used in the two extruders 5 are different. The two extruders 5 are respectively connected to the inner cavity and the outer cavity of the mold 6.

[0028] Compared with existing technologies, the present invention has the following advantages: The aforementioned alloy profiled pipe system and its production equipment, which utilizes multi-layer co-extruded polymer composites, features an alloy profiled pipe 1 with an integrally formed structure, resulting in increased strength under the same material usage. The outer wall of this alloy profiled pipe 1 is longitudinally corrugated, further enhancing the overall strength of the pipe. Compared to pipes with flat outer walls, it offers the advantage of material savings while maintaining the same strength. The connector 2 structure facilitates installation and provides high sealing performance.
