Integrated production device, method and application of Krah pipe and hollow wall pipe

The invention provides an integrated production device and method for a Krah pipe and a hollow wall pipe and application, and relates to the technical field of plastic pipeline production equipment. Two different types of pipelines can be manufactured in one machine by arranging the extrusion dies in different shapes, meanwhile, the first pressing wheel and the winding die are arranged in a spaced mode, the wall thickness of the hollow wall pipe can be controlled according to the interval, the second pressing wheel makes contact with the winding die and can be used for abutting against the winding pipe prepared in the winding die, and therefore the manufacturing efficiency of the hollow wall pipe is improved. And when the hollow wall pipe is prepared, melt glue is prevented from overflowing to influence the distance between two winding pipes in the hollow wall pipe. According to the device, two pipelines can be manufactured through one machine, the equipment investment cost is greatly saved, the hollow wall p
