Embodiment 1

[0028] The production method of the present invention is illustrated by taking the fixed-length intermittent extrusion process to produce steel mesh skeleton polyethylene (PE) composite pipe as an example.

[0029] According to the required length of steel mesh skeleton PE composite pipe, wind the corresponding length of steel wire on the steel wire spindle 19 of the first winding machine 5 and the second winding machine 7, and then install the steel wire spindle 19 on the positioning shaft 20 and get ready.

[0030] Add the PE raw material as the outer layer material of the protective layer 22, the PE raw material as the inner lining layer 26, and the special hot melt adhesive as the outer layer adhesive layer 23 and the inner layer adhesive layer 25 into the outer tube extruder 12 respectively. , In the inner tube extruder 1 and the rubber layer extruder 9.

[0031] The temperature settings for each section of the inner tube extruder 1 for extruding the inner layer material ...

Abstract

The invention discloses novel compound pipeline production equipment and a compound pipeline production method and belongs to the field of compound pipeline production technology. The novel compound pipeline production equipment comprises an inner pipe extrusion device, a steel wire winding device, a bond line extrusion device and an outer pipe extrusion device, wherein the steel wire winding device comprises a first winding machine and a second winding machine; both the first winding machine and the second winding machine comprise winding machine rotating discs; each winding machine rotating disc is provided with a locating shaft; a steel wire spindle is arranged on each locating shaft; a tension variation controller is arranged at the bottom of each steel wire spindle. According to the invention, the existing winding machines are upgraded and modified, so that uniform distribution of the steel wire or fiber and uniform and consistent tension size are realized, the reliability of stable compound pipeline quality is improved, the number of the steel wire or the fiber on the equal voltage withstanding grade condition is reduced, and the cost is decreased; as the fixed length batch-type extrusion production technology is adopted, the steel wire is not needed to be changed during the production process, hidden production safety dangers, for example, the steel wire head is exposed to the surface of the compound pipeline, are eliminated, the production efficiency is improved, and labor force and energy consumption are reduced.

Description

technical field [0001] The invention belongs to the technical field of composite pipe production, and in particular relates to a novel composite pipe production equipment and a composite pipe production method. Background technique [0002] Steel mesh skeleton plastic composite pipes have become the mainstay of our country because of their advantages such as high compressive strength, good economy, strong flow capacity, light meter weight, more convenient transportation and installation, and traceable detection. The number one product in reinforced thermoplastic piping. However, the traditional plastic composite pipe with steel mesh skeleton is made of two-way cross-helically wound steel wires to form a steel mesh, and the steel mesh is bonded and fused with the inner and outer layers by hot melt adhesive to obtain a strengthening effect. However, in the actual production process, because the steel wire itself is not fixed and easy to slip, the distribution of the steel wir...
