In the daily production of BEIREN series presses, blanket installation is one of the most common issues faced by press operators and maintenance personnel. As a representative domestic offset press, this model features strong parts interchangeability, low maintenance costs, and electrical systems mostly controlled by domestic PLCs. If not handled promptly, the consequences can range from compromised registration accuracy and print quality to extended downtime in severe cases.
1. Fault Symptoms: Uneven pressure after blanket installation, blanket wrinkling or detachment, smudging at the gripper edge, and difficulty in plate registration.
2. Cause Analysis: Uneven blanket tensioning, mismatched packing underlay, unsecured plate clamps, improper allowance settings, excessive packing thickness, and aged blankets that have lost elasticity. Given that BEIREN is a representative domestic offset press with strong parts interchangeability, low maintenance costs, and domestic PLC-controlled electrical systems, troubleshooting should prioritize checking key components and standard parameters.
3. Maintenance Guide: Tension the blanket symmetrically in steps; select packing underlay according to standards; lock the plate clamps securely and re-verify registration; replace aged blankets promptly.
4. Daily Maintenance: Establish standard records for blanket installation; document packing configuration; replace blankets at regular intervals. The above methods also apply to models such as BEIREN 300, BEIREN 400, PZ4880, and N300. For practical operation, refer to the domestic CNC system / centralized lubrication control and on-site conditions. For complex situations, it is recommended to seek professional maintenance assistance through the printm.cn platform.
