AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model belongs to the technical field of granulators. The compression roller assembly comprises a compression roller shaft; the compression roller shell is arranged on the compression roller shaft through a bearing assembly; the end cover assembly is arranged at the end part of the compression roller shell, and the end cover assembly comprises a first end cover and a second end cover; a first sealing structure is arranged between the first end cover and the compression roller shell; a second sealing structure is arranged between the first end cover and the second end cover; and a third sealing structure is arranged in a space defined by the first end cover, the second end cover and the compression roller shaft. The compression roller assembly is used for solving the technical problems that a common compression roller assembly is of a single-sealing structure, the sealing performance of internal grease is poor, external feed and dust easily enter the compression roller assembly, parts in a compression roller are seriously abraded, and the service life is shortened. The granulator comprises the compression roller assembly.
