Technical Field

[0002] Plastic calender is a machine that presses and stretches plastic into films of a certain thickness and surface shape, and can coat fiber curtain canvas or steel cord fabric with glue. Plastic calender is a machine composed of two or more rollers arranged in a certain form and working at a certain temperature. It is mainly used to produce various types of plastic films and PVC calendered artificial leather products.

[0003] After the plastic calender is finished working, it is usually necessary to cool down the roller of the plastic calender. At present, the roller of the plastic calender is cooled down by blowing cold air to the roller surface of the plastic calender through a cold air blower;

[0004] During the use of existing air coolers, the positions of the air coolers are fixed, resulting in limited coverage area of ​​the air coolers. The roller cooling mechanism of some plastic calenders adjusts the position of the air coolers simultaneously through multiple sets of driving devices. Although this increases the coverage area of ​​the air cooler, it also makes the internal structure of the roller cooling mechanism of the plastic calender more complicated and the cost is relatively high. For this reason, we propose a roller cooling mechanism for a plastic calender. Utility Model Content
