The maintenance and upkeep of the embossing machine have the following considerations:
1. Daily Maintenance
Cleaning Work
After each use, promptly clean the dust, paper scraps, and other debris from the surface of the embossing machine. These impurities may enter the internal transmission components or electrical elements of the machine, affecting its normal operation. A clean soft cloth can be used to wipe the machine's exterior, and for hard-to-clean areas, a small cleaning brush or a hairdryer (on the cool setting) can be used.
For the embossing roller, after work is completed, use a special cleaning solvent and a soft cloth to wipe it down, removing any residual ink, glue, and other substances from the roller surface. For example, if the embossing machine is used in the printing industry, residual ink may dry on the roller surface, leading to unclear embossing patterns or damage to the roller surface.
Check Component Connections
Check whether the connections between various components of the embossing machine are secure. This includes the fixing screws of the embossing roller, the tensioning wheel of the drive belt, and the fixing bolts of the motor. For example, if the fixing screws of the embossing roller are loose, it may cause the roller body to shake during the embossing process, leading to uneven embossing or even damage to the machine. Manually check for signs of looseness in the screws, and if necessary, use appropriate tools to tighten them.
Lubrication Work
Properly lubricate the key moving parts of the embossing machine, such as the bearing parts of the embossing roller, the drive chain, or the drive gears. Generally, a special mechanical lubricant can be used, following the lubrication cycle and amount specified in the machine's user manual. For example, if the drive gears lack lubrication, they will generate significant friction during operation, leading to increased wear and affecting the machine's transmission accuracy.
2. Regular Maintenance
Electrical System Check
Regularly check the electrical system of the embossing machine, including whether the wires are damaged, whether the plugs have good contact, and whether the components inside the electrical control box are functioning normally. An insulation resistance meter can be used to check the insulation resistance of electrical equipment to ensure it meets safety standards. For example, if the insulation layer of the wire is damaged, it may lead to leakage, posing a safety hazard.
For electrical control components, such as relays and contactors, check whether their contacts show signs of burning. If the contacts are burned, it will affect the on-off control of the circuit, causing the embossing machine to fail to start or stop normally. Fine sandpaper can be used to gently polish the burned contacts, or damaged electrical components can be replaced.
Maintenance of the Embossing Roller
Regularly check the wear condition of the embossing roller. After prolonged use, the surface patterns of the embossing roller will gradually wear down, affecting the embossing effect. Professional measuring tools can be used to measure the outer diameter and pattern depth of the embossing roller, and when the wear exceeds a certain limit, the embossing roller needs to be repaired or replaced.
For removable embossing rollers, they should be disassembled regularly for thorough cleaning and inspection. During disassembly and installation, care should be taken to avoid colliding with the embossing roller to prevent damage to its surface patterns. At the same time, the correct installation sequence and method should be followed to ensure that the embossing roller can operate normally after installation.
Maintenance of Mechanical Transmission Components
Check and adjust the drive belt or drive chain. If the drive belt shows signs of slack, it will lead to reduced transmission efficiency and may even slip. The tensioning wheel can be adjusted to appropriately tighten the belt. For the drive chain, check whether its links are damaged or elongated, and if necessary, replace some links or the entire chain.
Check and maintain the machine's reducer and other transmission devices. The gears and bearings inside the reducer need to have their lubricating oil replaced regularly, and their sealing performance should be checked to prevent oil leakage. At the same time, check whether the output shaft of the reducer is securely connected to components like the embossing roller, and if there is any looseness, tighten it promptly.
