Leakage-proof structure used for roller in open mill

Abstract

The invention provides a leakage-proof structure used for a roller in an open mill, wherein the leakage-proof structure is simple in structure, can effectively avoid oil leakage during operation and is high in production efficiency. The leakage-proof structure includes a roller body. A bearing is fixed on one end of the roller body. A bearing base is fixed on the bearing and is provided with an oil filling pipe. The oil filling pipe is connected to an oil cup. A pressing cover is arranged at a gap at one side of the bearing and is installed onto the roller body. An external peripheral surface of the pressing cover is attached to an inner wall surface of the bearing base. An end cover is arranged on the roller body, wherein a step-shaped circular surface is formed internally on the end cover. The inner circular surface of the end cover is connected to the external periphery of a mounting end of the roller body through screw threads and is pressed against the outer side of the pressing cover. An outer circumference of the end cover is contact with a gap of the roller. A sealing cover is arranged on the roller body and is fixed to the other side of the bearing through screws. A contact end surface between the bearing base and an outer end of the sealing cover is a concavo-convex surface, wherein sealing rings are arranged in both the concavo-convex surface of the bearing base and the pressing cover combined with the roller.

Description

technical field [0001] The invention relates to a mill for refining rubber, in particular to a leak-proof structure for a roller of the mill. Background technique [0002] The open mill is the abbreviation of the open rubber mixing machine. It is a rubber mixing machine with exposed rollers used by the rubber factory to prepare plasticized rubber, mixed rubber, or heat-mixed and molded. Therefore, the overall structure of the mill is relatively complicated, and during the long-term operation of the mill, due to the influence of vibration, wear, pressure, temperature and repeated disassembly and assembly, the oil leakage problem of the sealing part of each joint surface is very common. , There are common leakage of the joint surface of the mill and the leakage of the shaft head, which not only causes a large amount of waste of oil products, but also affects production efficiency, wear and tear caused by friction, and the sealing effect is not ideal.
