AI Technical Summary

Technical Problem

The existing cooling rollers have low heat exchange efficiency and poor temperature uniformity, resulting in a large temperature difference between the two ends of the cooling rollers, causing uneven shrinkage of the leather surface and exceeding the thickness tolerance.

Method used

Inside the cooling roller, a liquid inlet pipe, a liquid spraying horizontal pipe, and a liquid outlet horizontal pipe are installed. The coolant enters the liquid spraying horizontal pipe through the liquid inlet channel and is sprayed onto the inner wall of the roller. It then flows out through the liquid outlet horizontal pipe, forming multiple parallel coolant channels to improve heat exchange efficiency and ensure the uniformity of roller temperature.

Benefits of technology

It significantly improves the heat exchange efficiency and temperature uniformity of the cooling roller, solves the problem of large temperature difference at both ends of the cooling roller, and ensures uniform cooling of the leather surface and control of thickness tolerance.
