Flexible conduit molding process using intermittently reinforced flexible conduit secondary coating extrusion equipment

Abstract

The invention relates to a molding process using reinforced soft conduit secondary coating extrusion equipment, including a secondary coating extruder, an extruder head, a cooling water tank, pipe guide wheels and a tractor, and is characterized in that: the extruder The upper end of the head is connected with a pipe storage box, and the bottom of the pipe storage box is made with a conveying hole for conveying pipes and communicating with the extruder head; the pipe storage box is equipped with a storage wheel, and the storage wheel is output by the support shaft and the motor. Shaft connection, the outer side wall of the pipe fittings storage box is equipped with a motor to drive the rotation of the storage wheel; it also includes a vacuum fan. The advantages are: this equipment and process realizes the continuous extrusion of intermittently reinforced soft conduits, and the reinforced polyurethane pipelines produced by it are light in weight, extrusion-resistant, bending-resistant, and have controllable lengths, ensuring that the pipelines are flexible under any circumstances. Normal penetration, meet the use requirements of liquid and gas transportation pipelines under various conditions, improve the safety of gas and liquid transportation pipelines, especially suitable for the production of large batches of continuous long pipelines, and reduce production costs.

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
