Enhanced winding pipe and manufacturing method and device of enhanced winding pipe

Abstract

The invention discloses an enhanced winding pipe manufacturing method and an enhanced winding pipe manufactured through the enhanced winding pipe manufacturing method. According to the method, firstly, an enhancing belt is spirally wound around the outer surface of a structural wall pipe to from an enhancing layer, and then wrapping is conducted on the outer surface of the enhancing layer to form a sheet layer connected through hot melting. The method has the beneficial effects that through the hot melting manner that overlapping and wrapping are conducted on the adjacent two sides of a sheet, cold stress can be avoided effectively, and potential layering hazards are avoided. The invention further discloses an enhanced winding pipe manufacturing device. The enhanced winding pipe manufacturing device comprises a machine base, a fixing device capable of fixing the structural wall pipe, a drive device capable of driving the winding pipe to rotate and driving the structural wall pipe to move in a straight and reciprocating manner along a movable rack, a belt unwinding device through which the enhancing layer is wound around the outer surface of the structural wall pipe and a sheet wrapping device, wherein the sheet wrapping device is used for achieving the operation that the sheet is wound around the outer surface of the enhancing layer in an overlapping and wrapping manner so as to form the sheet layer connected through hot melting. The enhanced winding pipe manufacturing device has the beneficial effects of being simple in structure, convenient to operate, safe and reliable.

Description

technical field [0001] The invention relates to pipe material production equipment and its manufacturing method, in particular to a reinforced winding pipe, its manufacturing method and equipment. Background technique [0002] Structural wall pipe is a kind of structural wall pipe made of high-density polyethylene (HDPE) by compression molding or thermal winding molding process. The general structure includes double-wall corrugated pipe and winding structural wall pipe. The pipe is a new type of acid-resistant, anti-corrosion, pressure-resistant, non-toxic green environmental protection pipe, which is an environmentally friendly and energy-saving high-tech product. HDPE is a high-molecular polymer, which makes the structural wall pipe have good flexibility and overall external pressure resistance, and can ensure traffic safety when used on roads with super-heavy loads. In application, the reliability of structural wall pipe engineering under the same conditions will be impr...

Problems solved by technology

[0003] Traditional structural wall pipes include double-wall corrugated pipes with inner plane and outer corrugation and structural wall spiral pipe B-type pipes (structural wall pipes with irregular shapes), which have the advantages of light weight, less material consumption and high strength, but it is inconvenient to carry and construct , when dragged or impacted, it is easy to cause corrugated holes and depressions on the outer wall of the pipe, and it is difficult to fill the belly of the construction backfill; the traditional A-type pipe with structural walls with inner and outer planes (structural wall pipes with smooth inner and outer surfaces) It can overcome the shortcomings of inconvenient handling and construction, but it is heavy and consumes a lot of materials. Moreover, as we all know, the traditional A-type pipe production equipment with structural wall winding pipes with inner and outer planes has low efficiency and poor process controllability. First, extrude square pipes to cool and shape There is stress in the cold welding method of extruding melted glue and welding, and there is a hidden danger of delamination
