Technical Field

[0001] This utility model relates to the field of PI film roller press technology, specifically a heating structure for increasing the service life of the rubber rollers in a PI film roller press. Background Technology

[0002] In the existing technology, the rubber rollers of commonly used PI film roller presses have a short service life when heated, and the replacement frequency is high. The equipment rubber roller parameter debugging time is long, and the product quality confirmation cycle after replacing the rubber roller is long. They cannot achieve the required production output, and the cost is also high. Utility Model Content

[0003] The purpose of this invention is to provide a heating structure that increases the service life of the rubber rollers in a PI film roller press, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heating structure for increasing the service life of the rubber rollers in a PI film roller press, comprising a roller core, wherein a heating tube is provided through the inside of the roller core, and the outside of the roller core is covered with a rubber coating layer.

[0005] In a further optimization, the coating layer is a vulcanized layer.

[0006] Further optimized, the sulfidation layer is silicon dioxide with the molecular formula mSiO2.nH2O and a working pressure ≤8 bar.

[0007] Further optimized, the vulcanized layer has a hardness of 55-60A, a high temperature resistance of ≤350 degrees Celsius, a tensile strength of 5-5.5 MPa, an elongation of 180%-260%, and a resilience of 55%-60%.

[0008] In a further optimized configuration, both ends of the heating tube are fixedly connected to the roller core.

[0009] Beneficial effects

[0010] The heating structure provided by this utility model for increasing the service life of the PI film roller press roller heats the roller to about 190°C and applies a pressure of 2-5 bar to the PI film, so that the PI film is completely adhered to the product plate, extending the service life of the PI film roller press roller during operation, reducing changeover waste, and lowering production costs.
