A hdpe winding pipe production equipment

Abstract

The invention relates to production equipment for an HDPE winding pipe. The production equipment comprises a guide device, a winding device, a heating device, a filling device and a cooling device; the heating device comprises a heating block and a heat conduction pipe, wherein the heating block is arranged on the end surface to be bonded of the winding pipe, and the heat conduction pipe is connected to the heating block; the heating block is fixed to a machine frame through a support and is of a hollow structure; the heat conduction pipe introduces the hot airflow into the heating block and is used for heating the end surface to be bonded of the winding pipe; the guide device comprises a guide wheel; and the guide wheel comprises a rotating shaft, a roller body and blocking sheets, wherein the roller body is made of ceramic, and the blocking sheets are made of metal, one blocking sheet is located on the side to be bonded of a square tube, the other blocking sheet is located on the outer side of the square pipe, and electric heating assemblies for heating the blocking sheets are arranged in the blocking sheets. According to the production equipment, the end surface to be bonded ofthe winding pipe and the side surface of the square pipe can be heated at the same time, heating is uniform, the HDPE square pipe and melt adhesive can be completely bonded together in the bonding process, and the pipe can not be broken.

Description

technical field [0001] The invention relates to a production equipment of HDPE winding pipe. Background technique [0002] HDPE pipe is a replacement product of traditional steel pipes and polyvinyl chloride water pipes. It is mainly used in municipal engineering water supply systems, indoor water supply systems in buildings, outdoor buried water supply systems, buried water supply systems in residential quarters and factory areas, old pipeline repairs, Water treatment engineering piping systems, industrial water pipes in gardens, irrigation and other fields, etc. When the square tube is rolled, it is necessary to use molten resin glue for bonding and sealing. The existing technology is to install a heat gun near the correction roller to heat the square tube so that the square tube and the melt glue are better bonded. At the same time, this method has the disadvantages that the heating temperature is not high and it is not easy to be heated evenly, which leads to the weak b...
