Seal ring of roller

Abstract

The invention discloses a seal ring of a roller. The seal ring is trapezoid, and fiber cotton and rubber are sequentially covered outside two sides of the seal ring. The seal ring of the roller is simple in structure, scientific in design, resistant to high temperature and good in weather resistance. Simultaneously, abrasion resistance of a seal ring body is greatly improved, and service life of the seal ring is prolonged.

Description

technical field [0001] The invention specifically relates to a drum device, in particular to a super-large drum sealing ring. Background technique [0002] In the tobacco industry, the production equipment for shredded cigarettes adopts a drum design. Such as: shredded leaf dampening machine, tobacco stem dampening machine, warming and humidifying machine, flavoring machine, etc. The drum sealing ring (hereinafter referred to as: sealing ring) on ​​these devices is an essential key vulnerable part, and the sealing ring needs to work for a long time in a harsh environment of high temperature and humidity. [0003] The currently used sealing ring is cut from high temperature resistant fiber cloth, which has no elasticity and poor wear resistance. During use, the sealing ring will become hard and brittle over time, and partially rupture, which will lead to serious problems such as air leakage and wire leakage of the drum. Simultaneously also can cause the disorder of product...

AI Technical Summary

Problems solved by technology

[0003] The sealing ring currently used is cut from high temperature resistant fiber cloth, which has no elasticity and poor wear resistance

During use, the sealing ring will become hard and brittle with the passage of time, and local ruptures will occur, which will lead to problems such as air leakage and wire leakage of the drum.

At the same time, it will also cause disorder in the production site and waste of cut tobacco

The normal use time of this sealing ring is about one week, and the service life is short, and it takes about 3 hours to replace a new sealing ring, which is time-consuming and labor-intensive.

[0004] In addition, the current sealing ring is limited by domestic production equipment, and the maximum diameter that can be produced is 2.5 meters. Sealing rings with larger diameters can only rely on foreign countries, and imported parts have problems such as high price, long delivery cycle, and poor service.
