Abstract
The utility model discloses a novel non-return carrier roller, relating to the technical field of carrier rollers. A shaft is arranged at the middle position of a roller body, the end part of the shaft is provided with a bearing, a seal ring is arranged at one side of the bearing, an inner seal ring is arranged at the other side of the bearing, the inner seal ring is spliced with an outer seal ring, and the inner wall of the outer seal ring is matched with the outer wall of the shaft; and an inner retainer ring is arranged at the rear end of the inner seal ring, a seal disc is arranged between the outer seal ring and the inner retainer ring, the inner retainer ring is in clamped connection with the outer retainer ring, a baffle plate is arranged at one side of the outer retainer ring, and the baffle plate is connected with the retainer ring. Because a non-return device is additionally arranged on most of carrier rollers respectively, the novel non-return carrier roller has the advantages of simple structure, low cost, long service life and good non-return effect.
Description
Technical field
The utility model relates to the Idler Technology field, relates in particular to a kind of later-model Non-return idler.
Background technology
At present, existing belt conveyer prevents reversing through on cylinder, adding holdback, and so not only cost is high, and poor effect.
The utility model content
The purpose of the utility model provides a kind of later-model Non-return idler, and it adds holdback on most of carrying roller, simple in structure, and cost is low, long service life, and check is effective.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it is made up of roll body, axle, seal ring, bearing, inner seal ring, exterior seal ring, inner shield ring, outer back-up ring, baffle plate, back-up ring, seal disc; The midway location of roll body is provided with axle, and the end of axle has been located at bearing, and a side of bearing is provided with seal ring; The opposite side of bearing is provided with inner seal ring, and inner seal ring and exterior seal ring are pegged graft, and the inwall of exterior seal ring cooperates with the outer wall of axle; The rear end of inner seal ring is provided with inner shield ring, is provided with seal disc between exterior seal ring and the inner shield ring, and inner shield ring and outer back-up ring clamping; One side of outer back-up ring is provided with baffle plate, and baffle plate is connected with back-up ring.
Described axle is provided with spring, and the power when utilizing carrying roller to reverse is shunk spring, produces friction force with roller carrier shaft, makes the carrying roller check, and is respond well.
The end of described outer back-up ring is arranged between exterior seal ring and the axle 2.
The utility model adds holdback on most of carrying roller, simple in structure, and cost is low, long service life, and check is effective.
