The flexo press machine personnel must carry out a comprehensive inspection of the equipment, repair, lubrication, commissioning, wiping, and wait until the workshop is inspected before it can start production next time. At the end of each month, concentrate the force on the equipment for thorough maintenance.
1. Tension part: The tension control system is an important device to ensure the printing registration. The long-term high-speed operation of the equipment will often result in lower registration accuracy, poor registration sensitivity and large fluctuations. During maintenance, the tension control sensor and other devices must be inspected and the magnetic powder in the magnetic powder brake must be replaced.
2, transmission part: flexo printing machine color box gearbox under the condition of printing pressure, long-term high-speed operation will cause gaps in the bearing and gearbox internal bearing, resulting in lower concentricity, affecting registration accuracy. When it is severe, it will beat and affect the quality of the product. When repairing, replace the bearing in the gearbox according to the situation and adjust the gear clearance.
3. Unwinding and winding part: The loading and unwinding device should be used for long-term constant-speed operation under the pressure of the paper roll. Over time, the gap of the transmission gear will increase, which will affect the stability of the paper during the printing process. Gears, bearings, and gear support shafts should be replaced during repairs.
4. Electrical part: The electrical part of the flexo printing machine is the core of the machine. The dust inside the electric cabinet must be eliminated regularly to ensure normal operation.
5. Regularly check the pressure gauge, check the oil level of the oil level, and regularly replace the oil used in the gearbox of the flexo press. By systematically overhauling the equipment, the accuracy of the equipment can be restored, and the equipment can maintain a good operating state and ensure orderly production.
