Chinese dried Reuters recently, China Chemical Industry Guilin Engineering Co., Ltd. invention patent four composite rubber extruder head of Guangxi won the first patent inventions achievement trade fair project gold medal. The main performance and technical indicators of this equipment have reached the international advanced level. The compound rubber extruder is the key process equipment for tire production. It is composed of 4 sets of pin barrel cold feed extruders. The 4 different formulas are heated and plasticized by an extruder and then delivered to the compound head. Extrusion allows accurate control of extrusion product temperature, dimensional accuracy and extrusion speed to meet a variety of production process requirements. In addition, the machine-external laminating and out-of-machine compounding technology of the original tire production can be converted into a variety of in-machine composites. This is of great importance to improving the quality of tires, increasing productivity, and reducing energy and raw material consumption. In the production of sealant tapes, the three composite heads and four composite heads have also developed rapidly. In China, the compound head of the sealant strip production line that was introduced earlier is mostly equipped with a shear head. The structure of the head is relatively complex. After years of development, the three-composite and four-compound heads used today are quite simple and have good results. The shear head is no longer used. With the development of home-made composite extrusion equipment, compound extrusion technology and production technology will emerge a relatively rapid development. The localization of advanced equipment is conducive to new types of equipment and technology, improving the level of enterprise equipment and promoting production development, especially due to the rapid development of radial tire production in China and the advantages of pin-type cold-feed extruders in recent years. The application of the cold feed extruder has greater advantages, becoming a new generation of hot feed extruders and ordinary cold feed extruders, providing broad development and application prospects for pin-type cold feed extruders. .
