Flat screen printing machine is a common printing equipment, widely used in advertising, packaging, ceramics, textile and other industries. In order to extend its service life and ensure printing quality, flat screen printing machine needs regular maintenance and repair. The following are the basic steps and precautions for the maintenance and repair of flat screen printing machines.
1. Clean the printing table and embossing roller: Before using the flat screen printing machine every day, the printing table and embossing roller should be cleaned. You can use a damp cloth to clean, be careful not to use too much force to avoid scratching the print table and embossing rollers.
2. Clean the ink cartridge: you need to clean the ink cartridge every month. First, remove the ink cartridge and clean it, then put the ink cartridge into the cleaning box and soak it for 1 hour with detergent. After that, rinse the cartridge with water to make sure there is no residue inside the cartridge. Finally, dry the cartridge and reinstall it on the flatbed screen printer.
3. Replacement of screen printing: When the screen printing is found to be worn or damaged, it needs to be replaced in time. Care needs to be taken when removing the original screen print to avoid bending or deformation. When installing the new screen print, adjust the tightness according to the printing requirements to ensure the flatness of the screen print and good printing quality.
4. Calibrate the positioning: In the process of using the flat screen printing machine, due to vibration, collision and other reasons, it may lead to positioning deviation. Therefore, regular calibration positioning is necessary. When calibrating the positioning, you need to raise the screen print first, and then make the print position and position mark consistent by adjusting the positioning screw. Be careful when calibrating the positioning to ensure that the adjusting screws are not too tight or too loose, so as not to affect the print quality.
5. Check the ink supply system: The ink supply system is one of the key parts of the flat screen printer and needs to be checked regularly. First of all, check whether the ink cartridge is loaded and whether the ink in the cartridge is sufficient. If the cartridge is found to be insufficient, it needs to be replaced in time. In addition, it is also necessary to check whether the ink line is smooth and there is no clogging. If found clogged, you can use a special cleaning agent to clean, to ensure that the ink can be supplied to the screen printing smoothly.
6. Maintenance pressure roller: flat screen printing machine printing effect and the quality of the pressure roller has a great relationship, so maintenance pressure roller is very important. Regularly check whether the pressure roller is worn, if found worn, need to be replaced. For unworn pressure rollers, use lubricants for regular maintenance to reduce wear and ensure better printing results.
7. Downtime Maintenance: Flat screen printing machines need to be fully maintained before they are shut down for a long period of time. First of all, remove all the ink cartridges and ink tubes and clean them to prevent the ink from drying out. Then, cover the printing table, embossing roller, screen printing and other parts with a clean cloth to avoid the intrusion of dust and corrosive substances. Finally, clean and wipe the flat screen printing machine as a whole to ensure that the surface of the machine is clean and dust-free.
Precautions for maintaining the flat screen printing machine:
1. Before maintaining and servicing the flat screen printing machine, make sure the machine is completely stopped and disconnected from the power supply.
2. When using cleaning tools, select the appropriate tools to avoid damage to the equipment.
3. When cleaning the printing table and embossing roller, avoid excessive force to avoid scratching.
4. when cleaning the ink cartridge, avoid the cleaning agent to enter the inside of the ink cartridge, so as not to affect the ink quality.
5. When replacing the screen print, operate carefully to avoid bending or deforming the screen print.
6. When calibrating the positioning, adjust the screws carefully to avoid over-tightening or over-loosening.
7. When maintaining the pressure roller, be careful to use the right amount of lubricant and avoid excessive lubrication so as not to affect the printing quality.
The service life of the flat screen printing machine can be extended and the stability of printing quality can be ensured through regular maintenance and upkeep. In the maintenance process, pay attention to safe operation, choose the right tools and cleaning agents, and according to the specific conditions of the equipment. At the same time, it is also necessary to do a good job of maintenance before and during the shutdown to ensure that the equipment can operate properly in the next use.
