Abstract

The invention provides a circulating system of a roller coating machine. The circulating system comprises an upper coating roller, an upper taking roller, a lower coating roller and a lower taking roller; the upper coating roller is mounted on the strip steel inlet side; the upper taking roller is mounted below the upper coating roller; one side of the upper part of the upper taking roller makes contact with one side of the lower part of the upper coating roller; an upper coating charging tray is arranged below the upper taking roller; the lower part of the upper taking roller is located inside the upper coating charging tray; the lower coating roller is mounted on the strip steel outlet side; the lower taking roller is mounted below the lower coating roller; one side of the upper part ofthe lower taking roller makes contact with one side of the lower part of the lower coating roller; a lower coating charging tray is arranged below the lower taking roller; and the lower part of the lower taking roller is located inside the lower coating charging tray. According to the scheme, the circulating system is easy to mount, low in investment cost and small in occupied space.

Description

technical field [0001] The invention relates to the technical field of roller coaters, in particular, on the basis of the existing two sets of circulation systems, pumps and pipelines are cleverly arranged to add two additional sets of circulation systems to meet the capacity of one roll coater to produce four kinds of products. Background technique [0002] Roller coater passivation technology is a cutting-edge new technology. Passivation products include trivalent chromium, phosphating, chromium-free and anti-fingerprint. These 4 products are used in different industrial fields. The chemical components of these four passivation solutions are different and cannot be mixed, otherwise the chemical reaction will crystallize and solidify, blocking the pipeline. The passivation solution of the roller coater is very corrosive. From the raw liquid tank to the working tank to the feeding tray, and the feeding tray returns to the working tank, the circulation pipeline is very compli...
