HDPE/PP Spiral wound pipe machine (Large diameter spiral wound B type pipe machine)
- Process features:
- Spiral Hotwound pipe Extrusion Production line
Spiral hot wound Pipe Machine is mainly to produce HDPE+PP structured-wall spiral pipe in inner diameter from 300mm to 4000mm with diffferent ring stiffiness through changing the different size mandrel. Pipe is made of high-density polyethylene (HDPE) resin as the main raw material with hot wound technology, and cladding polypropylene (PP) single wall corrugated pipe as support structured layer. Its ring stiffiness can be up to 20KN/m2 (according to user needs, SN8; SN10; SN12.5; SN16), covering soil depth up to 20m.
Features of Extrusion line:
- Multi-Extruder units and corrugated pipe feeding system
1)The production line adopts PLC control system with intelligent human-machine interface, which is easy to operate;
2)Extruder system adopts high torque gear box and high efficiency screw;
3)The co-extrusion technology of four extruders can meet the requirements of various colors and raw material formulations;
4) Pipe Feeding unit is controlled by a servo motor with automatic induction storage pipe function;
5) Equipped with bottom sheet pressing function, Coating pipe guiding device, winding mandrel heating system
2.Moving spiral winding mandrel unit
The winding platform adopts precise linear guide rail, and its servo motor can control front , back and longitudinal movement. During production, the heated mandrel rotates on the moving platform, so that the extruded sheet and coated corrugated pipe can be tightly wound onto the mandrel. The platform is equipped with socket compaction device with adjustable spacing to ensure uniform and dense of socket.
3.Double station cutting milling system for socket spigot end
Place steel mandrel on the platform, remove steel rop at both side. Confirm the surrounding environment is safe, start with one button, controlled by the system modules, set the parameters to run automatically. After reach cutting time set by system, the cutting blade is automatically lifted and work according to the speed set by the system. With the action of cutting blades, the socket can be turn into the required styles. During the cutting process, the milling cutter at both ends of socket will realize automatic cutting without labour operation.After the cutting size is completed, the cutter will be retracted automatically.Air cooling, mist spray water cooling to the specified time, automatically stop. The system have an automatic chip suction system to avoid waste splashing.
- Demoulding, Weighing, Trimming units
- Finished pipe will be produced well here;
1). After the socket cut and trimmed, the pipe will be hoisted to the demoulding device for demoulding. The platform for demoulding is made of flexible buffer material to ensure the quality and the service life of the mandrel;
2).The pipe after demoulding is automatically turned over and transported to the automatic hydraulic lifting weighing platform, which displays the real-time production weight and records the real-time production data;
3).The pipe after demoulding is transferred to the trimming platform through the automatic hydraulic lifting weighing platform. Then manually trim the sockets. At the same time, an electric fuse is installed at the socket end, and the production of the finished tube is completed.
5.Copper wire winding machine
1) Automatic wire winding machine is used for the bending and winding forming process of electric melting copper wire, and it is also a necessary equipment for electric melting spiral tubes;
2) This machine is automatic modular control with stable production and convenient operation;
- Applicaiton:Drainage Pipe systems, Sewage pipe systems, Industrial pipes, Relining, Outfall pipes, Chemical tank, Marine structured wall pipe.
