1. Screw: Adopting the new generation of solid-liquid phase separation screw technology, which is the first to be used in China. The screw is divided into a multi-stage structure consisting of a forced feeding section, a melting solid-liquid phase separation section, a merging plasticization section, a homogenization section, and a forced mixing section. The screw adopts a large aspect ratio design, 33-38:1. The screw tube design has a forced extensionThe feeding system has feeding grooves with different structures on the inner wall of the screw cylinder to ensure rapid compression and advancement of materials. The extended forced cooling system is connected to the high-temperature screw using flanges, leaving a gap of 1-3MM to prevent heat from being transferred to the feeding section, ensuring rapid, high-pressure, and low-temperature propulsion of the material. The speed ratio of the gearbox adopts a design of 16-8:1 to ensure the high speed of the screw, coupled with a high-power kinetic energy system, thus achieving high speed and efficiency. Compared to ordinary screws, the production efficiency is increased by 30%, and the heating energy consumption is reduced by 20% This system has the advantages of high efficiency and speed, high extrusion volume, good yield, long service life, and stability and reliability.

2. Head: Made of 40Cr material, the grinding tool has high hardness and strong rigidity, and is not easily deformed under high temperature and pressure. The spiral flow channel adopts multi-layer spiral diversion, polished chrome plated grinding treatment, and flows smoothly and smoothly with low resistance. Clockwise rotation is exactly opposite to the direction of screw rotation, which can relieve the stress formed during the extrusion process of the released material, improve the strength of the pipe, and greatly reduce the phenomenon of pipe bursting. The expansion die and die mouth shrinkage adopt a 45 ° extrusion design to ensure good flowability and axial tension of the material during the molding process. The elongated straight section ensures that the material has high radial and axial strength after extrusion, and the cooled pipe is smooth and resilient, reducing the cost of raw material use and the strict requirements of plastic on the machine. Satisfy customers' general needs for low-pressure polyethylene, high-pressure polyethylene, high and low-pressure mixed polyethylene, and PP raw materials. Improved economic and social benefits.

3. Control system.

The control system adopts SiemensPLC centralized control, unique DCL software design, realizes the interconnection of systems, windows, and human-machine interfaces, endows machines with AI intelligence, perfectly realizes human-machine interconnection and remote control, and achieves one click control of equipment speed, pipe wall thickness, and production capacity. Intelligent control, simple operation. Save labor and effort, with no hidden safety hazards.

4、 Planetary cutting machine using Haff blocks

The Haff block is a whole circle divided into upper and lower parts, which can ensure that the pipe will not deform when clamped. After clamping the pipe with the Haff block, the pipe should be in a relatively static state, because there should be no shaking or deformation of the pipe during cutting, otherwise it will cause the saw to clamp, and in severe cases, it may even cause the motor to burn and the saw blade to break. The Haff block structure assists the planetary cutting machine, ensuring that the cut section is vertical and neat without the need for secondary processing. The designed saw foam collection system ensures a clean and tidy production site.
