                                                  Cooling Roller for Bi-Oriented Stretch Films

Introduction for Cooling Roller for Bi-Oriented Stretch Films:

At present, the internal structure of the  cooling roller for bi-oriented stretch films is divided into a double-layer single-flow setting and a double-layer double-flow setting. The internal medium is water or heat transfer oil. The internal structures of these two types are different, and the manufacturing processes are also different. Have a big impact on costs.

 1. Internal structure of expanded single-flow cooling roller: This model Cooling Roller for Bi-Oriented Stretch Films  is composed of an outer shell, an inner shell and a spiral baffle on the inner shell. Water or thermal oil circulates from the pipe into the internal single-flow thermal pipe, starting from the other side wall, thereby removing the heat. To achieve oxygen purpose.

 2. Internal structure of double-layer double-flow cooling roller: This model of Cooling Roller for Bi-Oriented Stretch Films is composed of an outer shell, an inner shell and a spiral baffle on the inner shell. Therefore, unlike the above, this heat-conducting roller adopts a double-layer double flow. Aluminum alloy recycling method. Water or thermal oil circulates from the duct pipe into the heat transfer duct through the internal flow. Its dual efficiency is high, the production process is complex, and the cost is high.
