1. Replace the lubricating oil in the worm gear reducer of the cardboard box machinery. Lubricating oil can be selected as No. 10, No. 20, or No. 30 engine oil.

2. After repairing each component, assemble the entire machine, start and operate it, and observe whether the machine is running normally. Heat the drum appropriately and add a small amount of specialized oil for cardboard packaging machinery to melt and cover the inner surface of the drum, then cut off all power supply. If necessary, spray paint on the surface of the machine, cover it with plastic paper after drying, and store it in a dry place.

3. If the chain is too loose, it can be adjusted by removing a few sections first. If it has been severely stretched, it should be replaced. When using cardboard machinery, it is necessary to follow a certain method and principle for maintenance and upkeep, and promptly solve different problems. When adjusting and replacing the chain, attention should be paid to the installation direction of the spring card at the chain joint, which should be consistent with the direction of the chain's operation to avoid impact, jumping, and even collision and detachment during operation.

4. Disassemble and clean all rolling bearings, and add new lubricating grease, which can be calcium sodium based.

5. Remove all dirt from the friction surfaces, especially clean the chain and sprocket, and refill with lubricating oil.
The maintenance and repair of cardboard packaging machinery require technical personnel to ensure the quality and performance of the machinery during use, and play an important role and value in the production of cardboard boxes.

6. Check if there is smoke leakage in the stove. If smoke leakage is found, the smoke blocking ring of the drum, stove, chimney, etc. should be inspected. If damage is found, it should be repaired and replaced in a timely manner. Electric heating models should be checked for damage to the electric heating tubes, and any damaged ones should be replaced. The development trend of corrugated cardboard equipment: improving production efficiency: mainly by increasing the operating width and speed of corrugated cardboard production lines or corrugated cardboard printing machinery, increasing the amount of work per unit time, and thus improving the production efficiency of corrugated cardboard equipment. In recent years, with the increasing demand for corrugated cardboard boxes in China and the continuous growth of cardboard box manufacturers, large-scale production has become the development trend of China's cardboard box manufacturing industry. Carton manufacturers need to carry out large-scale production, which puts higher demands on the production efficiency of corrugated cardboard machinery.
