Product Features
Modularization and Specialization
Modular production of plastic extruders can adapt to the special requirements of different users, shorten the research and development cycle of new products, and strive for a larger market share; And specialized production can arrange fixed-point production or even global procurement of various system module components of extrusion molding equipment, which is very beneficial for ensuring overall quality, reducing costs, and accelerating capital turnover.
Efficient and multifunctional
The high efficiency of plastic extruders is mainly reflected in high output, low energy consumption, and low manufacturing costs. In terms of functionality, screw plastic extruders are not only used for extrusion molding and mixing processing of polymer materials, but their applications have also expanded to fields such as food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics, etc.
Large scale and precision
The realization of large-scale plastic extruders can reduce production costs, which is more advantageous in large-scale twin-screw plastic granulation units, blown film units, pipe extrusion units, and other aspects. The major technical equipment required for national key construction services and one of the three key equipment supporting large-scale ethylene projects, the large-scale extrusion granulation unit, have long relied on imports. Therefore, it is necessary to accelerate the localization process to meet the development needs of the petrochemical industry.
Intelligence and networking
Modern electronic and computer control technology has been widely adopted in plastic extruders in developed countries. The process parameters of the entire extrusion process, such as melt pressure and temperature, temperature of each section of the machine body, speed of the main screw and feeding screw, feeding amount, ratio of various raw materials, current and voltage of the motor, are detected online and controlled by a microcomputer closed-loop system. This is extremely beneficial for ensuring stable process conditions and improving product accuracy.
Maintenance Method
- The plastic extruder equipment should be placed in a ventilated position to ensure the heat dissipation of the motor during operation and extend its lifespan; The machine should be well grounded.
- Regularly check the screws of the cutting tools. After using the new machine for 1 hour, use tools to tighten the screws of the moving and fixed knives, and strengthen the fixation between the blade and the knife holder; Lubricating oil should be regularly added to the bearings to ensure lubrication between them; To ensure the sharpness of the cutting edge of the tool, it is necessary to regularly inspect the tool to ensure its sharpness and reduce unnecessary damage to other components caused by blunt or missing blade edges; Regularly check whether the belt is loose and tighten it in a timely manner.
- Restart – Before the second startup, the remaining debris in the machine room should be cleared to reduce startup resistance The inertia cover and pulley cover should be opened regularly to remove the ash outlet under the flange, as the powder discharged from the crusher chamber enters the shaft bearing
- Component replacement – When replacing cutting tools, the gap between the moving and fixed blades should be 0.8mm for crushers above 20HP, and 0.5mm for crushers below 20HP The thinner the recycled material, the larger the gap can be adjusted appropriately
