Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing, and in particular relates to a processing device for an aluminum alloy lined plastic composite pipe. Background Art

[0002] Aluminum alloy lined plastic composite pipe is a new type of practical pipe developed on the basis of traditional plastic pipe. It combines the physical and chemical advantages of metal and plastic. In water supply pipe application, it has the characteristics of light weight, 100% oxygen resistance, anti-ultraviolet radiation, clean and hygienic, easy installation, strong sealing and maintenance-free.

[0003] In the prior art, Chinese utility model patent publication number CN212463535U discloses an electric heating needle for spraying aluminum alloy-lined plastic composite pipes, comprising a fixing seat fixedly connected to a round pipe, on which a plurality of extrusion mechanisms are provided... The electric heating needle for spraying aluminum alloy-lined plastic composite pipes can fix the composite pipe, facilitating electric heating treatment, and can fix composite pipes of different diameters through an extrusion rod that can be retracted or extended.

[0004] However, the existing electric heating needle for spraying aluminum alloy lined plastic composite pipes still has the following defects when used: by arranging a round pipe, a round hole, an extrusion mechanism, a round ring with a slide groove, a U-shaped clamp and a fastening bolt on the fixing seat, the composite pipe can be inserted into the round pipe and fixed by the extrusion of the extrusion rod, and the extrusion rod can be retracted as the round ring rotates, or extended as the spring resets, so that composite pipes of different diameters can be fixed. When fixing the composite pipe, the extrusion mechanism needs to contact the outer wall surface of the composite pipe, which will cause part of the outer wall surface of the end of the composite pipe (the part in contact with the extrusion mechanism) to be blocked, which is inconvenient for the subsequent spraying operation of the outer wall protective layer. In addition, the extrusion of the extrusion mechanism will cause the outer wall surface of the composite pipe to be compressed and damaged, which affects the subsequent spraying effect of the outer wall protective layer, resulting in poor use.

[0005] Based on the above situation, the present invention makes a further design based on the existing electric heating needle used for spraying aluminum alloy lined plastic composite pipes. Utility Model Content
