AI Technical Summary
The existing pressure roller assembly adopts a single sealing structure, which results in poor grease sealing, allowing external feed and dust to easily enter, causing serious wear of internal components and reducing service life.
A three-layer sealing structure is adopted, including a first sealing structure between the first end cover and the pressure roller shell, a second sealing structure between the first end cover and the second end cover, and a third sealing structure surrounded by the first end cover, the second end cover and the pressure roller shaft. An oil circuit is set on the pressure roller shaft to achieve uniform distribution of lubricating grease, and a temperature sensor is used to monitor the internal temperature in real time.
The sealing performance of the pressure roller assembly is improved, which prevents the entry of foreign substances, prolongs the service life, reduces the failure rate, reduces the waste of lubricating grease, and reduces production costs.
