What are the key points of daily maintenance of Flexo Printing Machine?

Flexo Printing Machine plays an important role in the printing industry. To ensure its stable operation and good printing quality, daily maintenance of Flexo Printing Machine is essential. The following are the key points of its daily maintenance:

1. Cleaning and maintenance

1. Regularly clean various parts of Flexo Printing Machine, including plate cylinder, impression cylinder, ink tank, ink fountain roller, etc. Use a clean soft cloth or special cleaning tools to remove dust, ink residue and other impurities. For example, at the end of each day's work, wipe the surface of the plate cylinder of the Flexo Printing Machine with a soft cloth to prevent the ink from drying and affecting the quality of the next print.
2. Clean the paper feeding system and paper collection system of the Flexo Printing Machine to ensure smooth paper transmission. Check whether there are paper scraps or debris accumulated on the conveyor belt, rollers and other parts, and clean them in time to prevent paper jams and other faults.
3. Clean the casing and control panel of the Flexo Printing Machine to keep the appearance of the equipment neat and tidy, and prevent dust from entering the control panel to affect the electrical performance.

2. Lubrication and maintenance

1. Lubricate the transmission parts, bearings, etc. of the Flexo Printing Machine regularly according to the requirements of the equipment manual. Choose appropriate lubricating oil or grease to ensure good lubrication effect and reduce wear and friction. For example, lubricate the transmission chain of the Flexo Printing Machine once a week to extend the service life of the chain.
2. Check the working status of the lubrication system of the Flexo Printing Machine to ensure that the oil circuit is unobstructed and the oil level is normal. If oil leakage or insufficient lubrication is found, repair and replenish lubricating oil in time.

3. Component inspection

1. Before starting the machine every day, check whether the various components of the Flexo Printing Machine are firmly installed and whether fasteners such as screws and nuts are loose. In particular, whether the installation position of the plate cylinder and the impression cylinder is accurate, and tighten them in time if they are loose.
2. Check the wear of the rubber roller, scraper and other easily worn parts of the Flexo Printing Machine. If severe wear is found, it should be replaced in time to ensure printing quality. For example, the wear of the scraper will affect the uniformity of the ink and needs to be checked and replaced regularly.
3. Check whether the electrical system of the Flexo Printing Machine is well connected, and whether the wires are damaged or aged. Ensure the normal operation of electrical equipment to prevent safety accidents caused by electrical failures.

4. Ink system maintenance

1. Regularly clean the ink system of the Flexo Printing Machine, including the ink pump, ink tube, ink cartridge, etc. Remove impurities and sediments in the ink to prevent clogging of the ink path. For example, perform a comprehensive cleanup of the ink system of the Flexo Printing Machine once a month to maintain the fluidity and purity of the ink.
2. Check the working status of the ink pump of the Flexo Printing Machine to see if there is abnormal noise or unstable pressure. If there is a problem, repair or replace the ink pump in time.
3. Adjust the viscosity and fluidity of the ink of the Flexo Printing Machine, and reasonably control the performance of the ink according to different printing materials and printing requirements to obtain the best printing effect.

5. Regular calibration

1. Regularly calibrate the Flexo Printing Machine, including color calibration, overprint calibration, etc. Use professional calibration tools and methods to ensure accurate printing colors and high overprint accuracy. For example, color calibration is performed once a quarter to ensure that the colors of different batches of printed products are consistent.
2. Check the pressure system of the Flexo Printing Machine, including the pressure between the plate cylinder and the impression cylinder, the scraper pressure, etc. Adjust the pressure to the appropriate range to ensure the printing quality and the normal operation of the equipment.
