plastic extruders are mainly used to extrude thermoplastics such as PE, PP, PS, PVC, ABS, PC, PET and other plastic materials. With the help of related downstream equipment (including slurries), various plastic products such as plastic pipes, profiles, sheets, plates, plastic pellets and so on can be produced.
What is the maintenance method of plastic extruder?
What are the product characteristics of plastic extruder?
What are the precautions for using plastic extruder?
⒈ The plastic extruder equipment should be placed in a ventilated place to ensure the heat dissipation of the motor and prolong its service life; The machine should be well grounded.
⒉ Check the die screws regularly. After using the new machine for 1 hour, use tools to tighten the screws of the moving blade and the fixed blade to strengthen the fixation between the blade and the tool holder; The bearings should be filled with lubricating oil regularly to ensure the lubricating ability between the bearings. ; To ensure the sharpness of knife cutting, the knife should be checked frequently to ensure its sharpness and avoid unnecessary damage to other parts caused by the bluntness of the knife edge; Regularly check whether the belt is loose, and adjust it in time.
3. restart - Before the second start, remove the remaining debris in the engine room to reduce the starting resistance. The inertia cover and pulley cover should be opened periodically to clear the ash outlet under the flange as the crusher chamber discharges powder. The material gets into the shaft bearing.
⒋Replacement of parts - When replacing the tool, the distance between the moving blade and the fixed blade: 0.8 mm is better for crushers above 20 HP and 0.5 mm is better for crushers below 20 HP. The thinner the recycled material is, the bigger the gap can be.
Modularity and specialization
The modular production of plastic extruder 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; While the specialized production can arrange the fixed point production of various system module components of extrusion molding equipment, or even carry out global production purchasing, which is very beneficial to ensure the quality of the whole period, reduce costs and accelerate capital turnover.
Efficient and multifunctional
The high efficiency of plastic extruders is mainly reflected in high performance, low energy consumption and low manufacturing cost. In terms of function, the plastic screw extruder has not only been used to extrude and mix polymer materials, but its use has been extended to food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics and other fields.
The use of a plastic extruder involves a series of links such as installation, adjustment, commissioning, operation, maintenance and repair of the machine. Its use has the commonality of general machinery, mainly in the aspects of the drive motor and the deceleration speed changing device. However, the working system of the plastic extruder is the extrusion system, but it has unique characteristics, and when using the plastic extruder, special attention should be paid to its characteristics.
