Sink roll with sealing device

Abstract

The invention provides a sink roll with a sealing device. The invention adopts a novel sealing structure in the sink roll in order to overcome problems in the prior art that the sink roll has big sealing damping, serious abrasion, frequent replacement, poor sealing effect and serious bath solution reveal; the sink roll is characterized in that a sealing structure arranged on a main shaft fixes thesink roll on a trough body and comprises an elastic element, a flange plate 8, a pressure pad 9, a cushion block 1, a stationary seal ring 11, a rotating seal ring 12, a rotating seal ring rubber support 13 and a hose clamp 14; the flange plate 8 presses the elastic element on the trough body; the stationary seal ring 11 is arranged at the back part of the elastic element and contacted with the rotating seal ring 12; the rotating seal ring 12 is regulated and sheathed on a spindle head by the rotating seal ring rubber support 13; and a butterfly nut causes a cushion block 10 to be connected with the flange plate 8 by the pressure pad 9. The sink roll with the structure has small sealing damping, flexible rotation, small abrasion, good sealing effect, effectively prevents the reveal, increases the production efficiency and reduces the manufacturing cost.

Description

technical field [0001] The invention belongs to the processing field of metal strips and relates to the application field of sinking rolls. Background technique [0002] At present, in the field of surface treatment of metal strips in China, ordinary sealing rings are used for the sealing of sinking rollers. image 3 In the existing sinking roller structure, a plastic ring 15 is placed at the contact between the sinking roller and the sealing ring 18, and the sealing ring 18 is pressed on the sealing flange 17 by the gland flange 16, and pressed on the tank body by the elastic element compensator 19 The upper connecting flange 20 is connected to each other. This type of sealing structure has a large damping when the sinking roller rotates, causing friction and heat generation of the sealing ring 18. The sealing ring is easy to wear and tear, and it is not easy to replace. It needs to stop production when replacing, which affects production efficiency. The sealing ring 18 The...

Problems solved by technology

[0003] In order to overcome the poor sealing performance between the sinking roller and the tank body in the prior art, the sealing ring is easy to wear when the sinking roller rotates, and it is not easy to replace, and production needs to be stopped when replacing, which affects production efficiency, easily leaks, causes waste of tank liquid, and pollutes the environment Seriously, the present invention adopts a sinking roller sealing mechanism with elastic elements, which improves the sealing quality, reduces the damping when the sinking roller rotates, has a good sealing effect, and reduces the degree of environmental pollution
