Description

TECHNICAL FIELD

[0001] The utility model relates to a rubber breaker roller technical field, concretely is a labyrinth seal ring type rubber breaker roller. BACKGROUND

[0002] Labyrinth seal, also known as zigzag seal or expansion cavity seal, its basic principle is to set a number of annular sealing teeth arranged in sequence around the rotating shaft or moving parts, and a series of interception gaps and expansion cavities are formed between the teeth. When the sealed medium (such as gas, liquid or particulate matter) tries to pass through these gaps, it will produce throttling effect, thereby reducing the flow rate and pressure of the medium, achieving the purpose of leakage prevention. The rubber breaker roller is an important part of rubber processing equipment, which is used to break the blocky rubber into smaller particles for subsequent processing and handling. During the breaking process, rubber particles and debris generated by breaking may enter between the roller shaft and bearing, causing equipment wear, failure and even shutdown. Therefore, most of the current rubber breaker rollers use labyrinth seal technology. However, the existing labyrinth seal ring type rubber breaker roller may have different degrees of wear between the inner roller and the outer roller after long-term work, which may cause the diameter difference between the two to increase and make them unable to rotate synchronously, thus affecting the working efficiency of the rubber breaker roller and lacking practicality.
