Heat mapping technology is a powerful tool for checking the heat distribution of calender rollers in high-volume packaging systems. These rollers are vital for ensuring consistent product quality, and non-uniform temperature can lead to print flaws, substrate warping, or delamination.

To use heat detection reliably, start by turning on the equipment and allowing the roller assembly to reach its design setpoint. This usually takes 20 to 45 minutes depending on the unit configuration. Once balanced, use a precision infrared imager to capture the entire surface of the roller. Position the camera at a fixed focal length and alignment to ensure reliable cross-section analysis across the roller’s length. Eliminate obstructions such as condensation, debris, or shiny coatings that might distort the readings.

Document heat maps along the full width and length of the roller, paying priority notice to the outer rims and core, غلطک پرس پرینتر as these areas frequently exhibit temperature variations. Identify excessive heat regions that are substantially hotter than the adjacent zones, or temperature dips that indicate poor thermal conduction. These anomalies could be caused by worn heating elements, faulty thermostats, uneven bearing pressure, or buildup on the roller surface.

Cross-reference the images to a reference heat profile taken when the machine was operating correctly. If variances are found, deactivate the system and assess the heater coils, thermal barriers, and mounting geometry. Routine infrared inspections, performed every 7–30 days depending on production volume, help prevent unexpected downtime and ensure uniform quality.

Always document your data and distribute to maintenance teams to analyze historical patterns. This proactive approach not only reduces wear and tear but also ensures higher quality output with minimal defects.
