AI Technical Summary

Technical Problem

In the prior art, insufficient heat exchange of the calendering rollers results in uneven temperature, which affects production efficiency and the quality of the calendered products and requires frequent shutdowns for adjustments.

Method used

A temperature-uniform calendering roller was designed. By installing an auxiliary heating tube on the liquid inlet pipe and setting partitions inside the roller to separate the cavity, multi-path heat exchange and flow control were combined to ensure uniform distribution and efficient flow of the heat exchange medium inside the roller.

Benefits of technology

It improves the heat exchange efficiency, ensures the temperature uniformity of the calendering rollers, reduces downtime for adjustments, and improves production efficiency and the quality stability of calendered products.

Abstract

The utility model relates to the technical field of calendaring machines, in particular to a uniform-temperature calendaring roller for a calendaring machine. According to the technical scheme, a connecting shaft and a sleeve are arranged at the two ends of a pressing roller respectively, a nut seat is arranged at the end, away from the pressing roller, of the sleeve, a liquid inlet pipe is inserted into the end, away from the pressing roller, of the sleeve, a first connector is arranged at the tail end of the sleeve, and the liquid inlet pipe is sleeved with an auxiliary heating pipe; partition plates are installed at the two ends of the interior of the pressing roller, the interior of the pressing roller is divided into a first cavity and a second cavity through the partition plates, second through holes are formed in the partition plates, and the first cavity and the second cavity are communicated through the second through holes of the partition plates. The multi-path heat exchange process is achieved by guiding the heat exchange media, and due to the fact that the heat exchange media flow in the multiple cavities, complex flowing modes such as eddy currents and turbulent currents can be formed, the heat exchange effect can be enhanced, and the heat exchange efficiency is further improved.
