Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of granulator rollers, in particular to a granulator roller with a bidirectional oil circuit. Background Art
[0002] The main working parts of the ring die pelletizer are the ring die and two pressure rollers. The bulk material is drawn between the ring die and the pressure rollers. The two relatively rotating parts gradually squeeze the material. The material is squeezed into the ring die hole and formed in the ring die hole. It is continuously extruded to the outer end of the ring die hole. The cutter then cuts the formed pellets into the required length. Finally, the pellets flow out of the machine. The ring die pelletizer realizes the process of converting bulk material into pellets. The pressure roller assembly and the main shaft combination device are the key components of the ring die pelletizer. The pressure roller assembly and the main shaft combination device include two pressure roller assemblies and a main shaft. Each pressure roller assembly The ring die pellet mill consists of a pressure roller, an eccentric pressure roller shaft and a pair of bearings. Since the bearings in the pressure roller assembly and the main shaft combination device need to be lubricated continuously and the bearing temperature will continue to increase during operation, the pressure roller assembly and the main shaft combination device must have an oil circuit to ensure that the bearings maintain normal operation. Once the bearings are insufficiently lubricated or damaged, the entire ring die pellet mill will be shut down, resulting in great losses. Therefore, the quality of the oil circuit system of the pressure roller assembly and the main shaft combination device is directly related to the quality of the entire ring die pellet mill and plays a very important role in the ring die pellet mill.
[0003] Although the existing pressure roller assembly is equipped with inlet and outlet oil passages to continuously lubricate the bearings to ensure that the bearings maintain normal operation, the inlet and outlet oil passages do not form a good lubrication cycle, resulting in lubrication blind spots in some areas of the bearings. Impurities in the oil will continue to accumulate in this area, reducing the lubrication effect of the bearings and relatively shortening the service life of the bearings.
[0004] Therefore, it is urgent to provide a granulator roller with a two-way oil circuit to solve the above problems. Utility Model Content
