fig. 2 is an enlarged view of the position A of the present invention.

Illustration of the drawings: 1. a plastic alloy inner tube; 101. an inner layer; 102. an outer layer; 103. hollowing out the supporting layer; 2. a plastic alloy outer tube; 201. an anti-wear layer; 3. a support block; 301. a hollow region; 302. a convex region; 303. an inner concave region.

Detailed Description

The environment-friendly plastic alloy composite pipe of the present invention will be further described with reference to fig. 1-2.

Referring to the attached fig. 1, the environment-friendly plastic alloy composite pipe of the embodiment includes a plastic alloy inner pipe 1 and a plastic alloy outer pipe 2, and is characterized in that: a supporting block 3 is further arranged between the plastic alloy inner pipe 1 and the plastic alloy outer pipe 2, the plastic alloy 1 inner pipe is divided into an inner layer 101, an outer layer 102 and a hollow supporting layer 103 arranged between the inner layer 101 and the outer layer 102; through supporting shoe 3, can play the effect that supports to compound pipe, increase the crushing resistance that accords with the pipe, avoid compound pipe to appear breaking under the effect that receives the external force, fretwork supporting layer 103 also can effectually play the effect of resistance to compression in the time of save material simultaneously.

Referring to fig. 1-2, the hollow supporting layer 103 is triangular; through the design of triangle-shaped, can increase the stability and the compressive capacity of fretwork supporting layer 103.

Referring to fig. 1-2, the supporting block 3 is provided with a hollow area 301, an outward convex area 302 adapted to the plastic alloy outer tube 2, and an inward concave area 303 adapted to the plastic alloy inner tube 1; can save material's use environmental protection more through hollow region 301, laminating plastic alloy outer tube 2 and plastic alloy inner tube 1 that evagination region 302 and indent region 303 can be better play spacing fixed effect to supporting shoe 3 simultaneously, increase the structural stability of pipeline.

Referring to fig. 1, an abrasion-proof layer 201 is further disposed on the plastic alloy outer tube 2; can effectually avoid plastic alloy outer tube 2 to receive wearing and tearing at the in-process of using through abrasionproof layer 201, increase composite pipe's life.

The utility model discloses a forming process as follows: firstly, heating and extruding the inner layer 101 by an extruder to form the inner layer 101, enabling the inner layer 101 to run to a supporting layer 103 sleeving machine through conveying equipment, sleeving the supporting layer 103 on the inner layer 101 through the sleeving machine, covering the outer layer 102 on the supporting layer 103 through a forming die of the outer layer 102, shaping the supporting layer through a cooling device, and rolling a bonding agent on the outer layer 102 through a roll coater after shaping; and the outer layer is attached to the supporting block 3 and the pipe wall of the plastic alloy outer pipe 2 when the plastic alloy outer pipe 2 is pushed into the pipe pushing machine, the rotary pipe pushing machine stops working after the pipe body completely enters the plastic alloy outer pipe 2, and the pipe body completely enters the plastic alloy outer pipe 2 and rotates, so that the binder is uniformly coated between the plastic alloy outer pipe and the plastic alloy outer pipe, and the forming of the pipe body is completed after the plastic alloy outer pipe and the plastic alloy outer pipe are cooled and fixed.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
