The key points of carton machinery maintenance and repair are as follows:

Disassemble and wash all rolling bearings and add new grease. Calcium sodium base grease can be used.

Remove the dirt on all friction surfaces, especially the chain and sprocket, and refill the lubricating oil.

Check the stove for smoke leakage. If smoke leakage is found, check the drum smoke retaining ring, stove and chimney. If damage is found, repair and replace it in time. For electric heating models, check whether the electric heating pipe is damaged, and replace it if damaged.

Replace the lubricating oil in the worm gear reduction box of carton machinery. The lubricating oil can be No. 10, No. 20 or No. 30 engine oil.

After all parts are repaired, assemble the whole machine, start the machine and observe whether the machine operates normally. Heat the drum properly, and put a small amount of special oil for carton packaging machinery to melt and cover the inner surface of the drum, and then cut off all power supply. If necessary, the surface of the machine can be sprayed with paint. After drying, it shall be covered with plastic paper and stored in a dry place. If the chain is too loose, it can be adjusted by removing several sections. If it has been seriously elongated, it should be replaced.
