Plastic Pipe Making Machine

The plastic pipe production line is composed of control system, extruder, die head, shaping cooling system, tractor, cutting device and turning frame. Each pipe production line has two extruders. One of the main extruders uses powerful conveying bushings and high-efficiency screws, and the other smaller extruder is used to extrude the marking line. If the production of multi-layer co-extruded pipes requires additional extruders to achieve multi-machine co-extrusion.


The plastic pipe extruder adopts high-efficiency screw, slotted barrel, and strong water jacket cooling, which greatly improves the conveying capacity and ensures high-efficiency extrusion; high-torque vertical structure gear box; DC or AC drive motor. The basket-type composite die head suitable for processing has the characteristics of convenient adjustment and uniform discharge, which not only ensures the stability of high-efficiency extrusion, but also realizes the minimum stress and the highest pipe quality brought by low melt temperature. Adopting high-efficiency double-cavity vacuum sizing technology and spray cooling water tank, the sizing sleeve adopts a unique slotting process and water ring cooling to ensure the forming accuracy of the pipe, improve the yield of the pipe, and meet the needs of high-speed production. The multi-track tractor is adopted, and the traction force is even and stable. Each track is driven by an independent AC servo motor, and the drive technology controlled by a digital controller realizes accurate speed adjustment to achieve a high degree of synchronization. The cutting machine adopts high-speed and precise design, the cutting section is flat, and is equipped with a powerful chip suction device. The cutting machine takes the fixed-length work switch signal as a command to complete the whole cutting process, and keeps synchronization with the pipe operation during the cutting process. The turning action of the turning frame is realized by the air cylinder through the air circuit control. The turning frame is equipped with a limit device. After the cutting saw cuts the pipe, the pipe continues to be transported. After a delay, the cylinder enters the work to realize the turning action. The purpose of unloading. After unloading, it will automatically reset after a few seconds delay, and wait for the next cycle.

PPR fiberglass pipe making machine/PPR pipe production line
The PPR fiberglass pipe making machine is composed of two extruders co-extrusion, a mold, a vacuum water tank, a spray water tank, a tractor, a cutting machine, and a discharge frame.The PPR pipe production line produce the glass fiber reinforced PP-R (FR/PP-R) pipes are high-performance pipes produced at low temperature and high speed through special processes and equipment using multi-layer co-extrusion.The fiber glass pipe advantages:1. The linear expansion coefficient is only about 20~30% of ordinary PP-R products; it completely solves the problem of plastic pipe expansion and contraction.2. The rigidity of the pipe is increased to prevent the pipe from sagging, and at the same time, the density and number of fixed support points are reduced, thereby reducing the overall cost of the project.3. The pressure rating is higher, and the service life is longer under the usual design tremor.4. Better high temperature resistance and obvious energy saving and consumption reduction effect; FR/PP-R is used in hot water system, and the normal use temperature can reach 95~100℃, which not only increases the temperature of the medium used, but also reduces the heat preservation material Thickness, its overall cost is lower.5. Large water flow: Under the same level of pressure, the wall thickness of FR/PP-R pipe is thin, which increases the inner diameter of the pipe, thereby increasing the water flow (increase by 20%).6. The oxygen permeability problem of the pipeline is solved, and the inner surface directly in contact with water has good sealing performance and will not form sphagnum moss. The composition of the middle layer of the FR/PP-R pipe reinforced by glass fiber completely isolates the outside air from penetrating into the pipe, thereby inhibiting the growth of algae and keeping the water quality fresh and pure
