I. Core Wear-Prone Components
1. Squeegee System
The rubber squeegee blade is prone to nicks or deformation due to prolonged friction, leading to printing streaks or ink buildup.
Wear on the metal squeegee blade edge can cause uneven ink penetration, resulting in light-colored streaks.
2. Transmission Components
Gear tooth surfaces may experience galling or pitting due to overload or poor lubrication, affecting registration accuracy.
Chains/timing belts are prone to stretching or slipping under prolonged stress and require regular tension adjustment.
3. Screen and Printing Table
Wear on the inner wall of the screen can damage the squeegee, causing periodic streaks.
Aging or scratches on the printing table's adhesive layer can cause misalignment of the substrate.
II. Auxiliary System Wear
1. Pneumatic Components
Aging of cylinder seals leads to lifting delays, affecting screen repositioning accuracy.
Dust accumulation in solenoid valves may cause unstable air pressure; the filter element needs regular cleaning.
2. Servo System
Encoder signal interference or bearing wear can cause positioning drift and requires regular calibration.
III. Wear Prevention Suggestions
Check the squeegee condition daily and replace worn rubber blades promptly.
Lubricate transmission components monthly, using high-temperature lubricating oil to reduce wear.
Calibrate the servo system positioning accuracy quarterly and adjust PI parameters.
