Disassembly and overhaul

a. Remove the upper cap bolt, open the safety interlock switch, and open the cover

b. Remove the feed plate

c. Disconnect and check the universal joints of pull-down rollers, rotary knives and hydraulic motors

d. Dismantling check synchronous gearbox

e. Disassemble and check the upper and lower rollers and both ends of the bearing

f. Disassemble and check scraper, fixed knife

g. Disassemble and inspect the rotary knife and the eccentric bearings at both ends

Daily maintenance content:

a. Keep the pelletizer clean and tidy, timely clean the pelletizer dust and scattered pellets

b. Check the operating condition of the pelletizer at any time, pay attention to whether there is abnormal sound and clogging of the pellet chamber

c. Timely removal of agglomerates in the strip to prevent bulk material from entering the pelletizer

d. Prevent foreign materials such as metal from entering the pelletizer

e. When the bar is started, a small amount of the head is introduced and removed. When producing high-impact products, no more than 5 strips are used for the first time, and afterwards a single stick is introduced. 

Operational failures and possible causes:

a. Pellet too flat - too small lead gap

b. slice with burr ----- too large gap. Fixed knife or hob

c. Difficulties in the strands on the guide wire plate ----- too large lead gaps or insufficient front air pressure in the feed axis. Water adjustment is not good. Picking speed is too low

d. Fine filaments wound around the draw shaft - - - - Residual melt drips from the spinneret, especially low viscosity polymers. Lead axis scratch gap is too large
