1. The extruder should run forward to prevent reverse rotation.
2. Do not run on an empty stomach, and be sure to run the machine with heating and feeding, so as to prevent sticking (shaft holding) phenomenon.
3. It is strictly forbidden to add ironware and other miscellaneous materials into the feed port and vent hole of the extruder to avoid safety accidents and interference with production.
4. Safe use of electricity and grounding wire.
5. When the machine is running, it is strictly prohibited to touch the rotating parts such as the feeding port, the discharging port, the belt, the gear, etc.
6. Before using the machine, inject lubricating oil to avoid damage to the machine.
Plastic extruder, one of the three major synthetic materials, has developed rapidly since its inception. Plastics to replace steel, plastics to replace non-ferrous metals, plastics to replace cement, etc., are widely used in various fields such as agriculture, building materials, packaging, machinery, electronics, automobiles, home appliances, petrochemicals and national defense, extruders, and people's daily lives. . Therefore, it can be predicted that in the 21st century, plastics will be one of the more important raw materials for human activities.
Extrusion machine design Since extrusion molding is the main form of plastic processing, it is of great significance to develop plastic extrusion molding technology and equipment. Internationally, there are three main types of new mixing equipment used for the blending and modification of polymer materials: co-rotating parallel twin-screw extruders, reciprocating screw mixers and tandem disc extruders. Among them, the small co-rotating parallel twin-screw extruder can be produced in China, and the extruder technology but the 10,000-ton level large-scale mixing press and granulation unit all rely on imports. At the same time, the reciprocating screw kneader and tandem disc extruder are necessary devices for the preparation of high-filling and high-value-added polymer alloys. At present, the domestic research and development of them is just in the prototype stage, and the specifications are not many and the varieties are not complete. Broad prospects for development.
