[0021] Working principle: Through the 12-liter capacity of the material barrel, the outlet connection joint can be directly connected to the base, so that it is easy to disassemble and replace the material. The pressure value of the material in the storage barrel is controlled by the pressure regulating valve. The pressure can control the volume of material entering the cylinder and the ratio of AB extrusion. The extrusion of AB material is controlled by the cylinder 15 and extruded synchronously. The mixing block and static mixer at the outlet enter the mold and are heated and vulcanized. Figure 4This device is used to add a third agent. Its control principle is the same as that of the AB material, with a ratio of 2% of the total AB volume. Both the AB material and the third agent are monitored by pressure sensors, providing real-time control of the material pressure. It automatically adjusts extrusion pressure and flow rate, controlling the material ratio and the third agent ratio to meet various process requirements and produce high-quality products.
