Maintenance method of plastic extruder

First, the plastic extruder should be placed in a ventilated position to ensure the heat dissipation of the motor and prolong its life. The machine should be well grounded;

Second, check the tool screws regularly. After using the new machine for 1 hour, use tools to tighten the screws of the moving knife and the fixed knife to strengthen the fixity between the blade and the knife holder; the bearings should be filled with lubricating oil regularly to ensure the bearings. Lubricity, in order to ensure the sharpness of the cutting tool and reduce unnecessary damage to other parts caused by the bluntness of the knife peak, regularly check whether the belt is loose and tighten it in time;

Third, when restarting the plastic extruder, the remaining debris in the machine room should be removed to reduce the resistance of starting. The inertia cover and pulley cover should be opened regularly, and the ash outlet on the west side of the flange should be cleared. The powder discharged from the chamber enters the shaft bearing;

Fourth, replace the parts. When changing the cutter, the gap between the moving knife and the fixed knife; 0.8MM is better for crushers above 20HP, and 0.5MM is better for crushers below 20PH. The thinner the recycled material, the gap can be adjusted appropriately;
