Reinforcing flexible guide pipe secondary coating extrusion device and molding process

Abstract

The invention relates to a reinforcing flexible guide pipe secondary coating extrusion device and a molding process. The reinforcing flexible guide pipe secondary coating extrusion device comprises a secondary coating extruder, an extruder head, a cooling water tank, pipe fitting guide wheels, a dragger and a vacuum fan. The reinforcing flexible guide pipe secondary coating extrusion device is characterized in that the upper end of the extruder head is connected with a pipe fitting material storage tank; the bottom of the pipe fitting material storage tank is provided with a conveying hole which is used for conveying pipe fittings, and is communicated with the extruder head; the pipe fitting material storage tank is internally provided with material storage wheels connected with a motor output shaft through a support shaft; one side wall outside the pipe fitting material storage tank is provided with a motor for driving the material storage wheels to rotate. The reinforcing flexible guide pipe secondary coating extrusion device has the advantages that intermittent reinforcing flexible guide pipes are extruded out continuously through the device and the process; the produced reinforcing polyurethane pipelines are light in weight, and controllable in length, resist extrusion and bending, guarantee the normal pipeline running under any circumstance, meet using requirements of liquid and gas conveying pipelines under various conditions, and improve the safety of gas and liquid conveying pipelines. The reinforcing flexible guide pipe secondary coating extrusion device and the molding process are especially suitable for the production of continuous long pipelines on a large scale, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to secondary coating extrusion equipment and a molding process for reinforced soft conduits. Background technique [0002] The field of plastic processing technology embodies the achievements of modern science and technology in many fields. At present, many liquid and gas transportation pipelines used in different application fields not only need to have the characteristics of extrusion resistance, bending resistance, and light weight, but also need to be controllable in length to meet Different requirements, to ensure the normal penetration of the pipeline under any circumstances. In order to meet the many performances of the above-mentioned conveying pipelines, it is necessary to embed steel wire elastic reinforcing linings in the pipe walls of traditional conveying pipelines, while the extruders used in the known technology for processing plastic pipes with...

Problems solved by technology

In order to meet the many performances of the above-mentioned conveying pipelines, it is necessary to embed steel wire elastic reinforcing linings in the pipe walls of traditional conveying pipelines, while the extruders used in the known technology for processing plastic pipes with reinforced linings for secondary coating extrusion equipment The head is generally designed according to the length of the pipe body to be processed, and the length of the reinforced pipe produced is only 300-500mm, and when the vacuum degree cannot meet the vacuum degree required by the process, it will not only lead to poor coating, but also cause delamination , but also affect the quality of the product
