Description

Cooling air ring

Technical Field

The utility model relates to a blown film equipment technical field, concretely relates to cooling air ring.

Background

The air ring is one of the matching devices commonly used for cooling the film bubble in the blown film forming, and is a necessary device of a film blowing air cooling system, in the film blowing processing process, the air brought by the fan is taken as a cooling medium by the air ring to cool a film bubble inflation area, when the cooling air blows to the film bubble through the air ring, the high-temperature film bubble is in quick contact with the cold air and exchanges heat, and the heat on the film bubble is quickly dissipated through air transfer, so that the film bubble is cooled.

The film bubble temperature is high, and blown film aircraft nose temperature can be higher, and it is just more that its heat of conducting for the wind ring is just more, can make the interior current wind of wind ring obtain more heats, if not handling, the wind temperature that the wind ring blown out the wind can be higher. In addition, the plastic processing temperature is high, the more heat the processing equipment radiates to the surrounding environment, and because the plastic film blowing place is a certain closed space indoors, the heat dissipation effect is not good, so the air temperature of the surrounding environment can be continuously increased along with the extension of the processing time. The inlet air of the air ring is usually taken from the ambient air, and the temperature of the inlet air and the outlet air of the air ring is increased along with the temperature increase of the ambient air. In this situation, it is difficult to achieve a desired cooling effect of the bubble.

The above problems are problems that the art needs to solve.
