Description

Technical Field

[0001] The invention relates to the technical field of ironing machines, and in particular to an ironing roller for a double-roller ironing machine. Background Art

[0002] Ironing is a common fabric processing process in the textile industry. By using ironing rollers to heat and compact the fabric, the surface of the fabric becomes smooth and bright, while improving its wear resistance and wrinkle resistance. The heating methods of the ironing rollers in the ironing machine include thermal oil circulation heating, electric heating, etc. The utility model patent with patent number 2013202590733 discloses a thermal oil circulation heating device. However, the temperature on the surface of the ironing roller is unstable and fluctuates greatly; the heating process is slow, and the oil heating method is prone to leakage and pollution. If gas heating is used, it is easy to cause the loss of gas heat, increase losses and increase thermal pollution;

[0003] For example, the application number CN202323107997.4 discloses a polishing roller for a textile polishing machine, which specifically includes a polishing roller body component and a heating component.

The inner sleeve is arranged in the polishing roller body, and the outer copper sleeve is connected to the polishing roller body. The heating component is arranged in the inner sleeve. When the device is heated, the inner sleeve is heated by the heating component.
