Daily maintenance of PP plastic sheet production line extruder

Routine maintenance of the PP plastic sheet production line is a periodic routine operation that does not take up the running time of the machine equipment and is generally completed at startup. The key to daily maintenance of the extruder is to clean the equipment, grind all moving parts, tighten loose threaded parts, check and align the motor immediately, control appearance, spare parts and pipes, etc.

Usually after the extruder has been running continuously for 2500-5000 hours, repair and maintenance are carried out on time. It is necessary to disassemble and inspect the equipment, identify the damage of key spare parts, and replace the parts that have reached the normal damage limit to repair the damaged parts.

The PP plastic sheet production line is not allowed to run idling to prevent screw and machine wear.

If there is any abnormal noise during the operation of the extruder, it should be stopped immediately and inspected or repaired.

Resolutely prevent metal materials or other debris from falling into the hopper to prevent damage to the screw and barrel. In order to prevent iron debris from entering the barrel, magnetic components or magnetic racks can be installed at the inlet of the barrel to prevent debris from falling into the barrel, and the materials must be screened in advance.

Pay special attention to keeping the environment clean, and do not let waste impurities mix into the material and block the filter plate, affecting the output value and quality of the product and the resistance of the adding machine head.

When the extruder is not used for a long time, anti-corrosion grease should be applied to the screw, cover, machine head and other surfaces. Small screws should be hung in the air or placed in a special wooden box with wooden blocks to prevent the screws from being deformed or bruised.

Calibrate the temperature control electronic instruments of the PP plastic sheet production line on time to check its adjustment accuracy and flexibility.
