Abstract

The utility model relates to the field of band steel rinse and discloses a rinse bath with a wringing roller synchronizing mechanism, the rinse bath consists of an upper wringing roller (4) and a lower wringing roller (5). The upper wringing roller (4) is connected with a power device, and the upper wringing roller is connected with the lower wringing roller through a synchronizing mechanism. In this way, the lower wringing roller can realize active rotation and rotate synchronously with the upper wringing roller (4). As no relative velocity exists between the wringing rollers and a band steel, a synchronous squeeze is conducted to the band steel, thereby overcoming the technical problem that skid is unavoidable between the band steel (6) and the lower wringing roller (5) due to the passive rotation of the lower wringing roller (5) of the prior rinse bath, avoiding scratches caused to the band steel (6) by the lower wringing roller (5), protecting the working surface of the wringing rollers, prolonging the service life of wringing rollers, bringing the functions of wringing rollers into full play and improving the wringing effect. The rinse bath with the wringing roller synchronizing mechanism needs less equipment, has excellent improvement effect, and is particularly applicable to band steel zincification and color-coating machine sets.

Description

The rinse bath of band squeeze roll lazy-tongs

Technical field

The utility model relates to the band steel and cleans field, especially a kind of squeeze roll with lazy-tongs that is applied to the steel rinse bath.

Background technology

Before strip steel Zn-plating and color coating processing, need the cleaning tape steel, after the cleaning, also need to extract the liquid of belt steel surface.Referring to Fig. 1, usually the U.S. steel connection method rinse bath that adopts is such, in vertical direction, the upper and lower surface of band steel is equipped with one respectively and goes up squeeze roll and following squeeze roll, following squeeze roll keeps tangent with the travel line of being with steel and arranges that perpendicular to band steel center line horizontal direction following squeeze roll is by its passive transport of frictional force drives of band steel and squeeze roll; Last squeeze roll is realized opening and closing action by two double-acting cylinders, and by its running of AC motor-driven.The rinse bath of this kind structure in use, be that Main Ingredients and Appearance is between the alkali lye of NaOH saponification to take place to carry out the cleaning of belt steel surface in ROLLING OIL by belt steel surface and the rinse bath, the product of saponification is attached to belt steel surface, reduced the frictional force of band steel with following squeeze roll, squeeze roll and the phenomenon of being with steel to skid down appear, showing as down squeeze roll rotates slowly even stops operating, make between band steel and the following squeeze roll and produced relative motion, caused of the scuffing of time squeeze roll on the one hand to belt steel surface, thereby influence zinc-plated unit ordinary production and galvanizing production plating prebasal plate also promptly with the quality of steel, cause destruction on the other hand again, shorten the service life of squeeze roll the squeeze roll working face.

The utility model content

In order to overcome the existing deficiency of easily skidding between troughed belt steel and the following squeeze roll of cleaning, technical problem to be solved in the utility model provides a kind of rinse bath of the band squeeze roll lazy-tongs of squeeze roll active rotation down.

The technical scheme that its technical problem that solves the utility model adopts is: the rinse bath of band squeeze roll lazy-tongs, comprise squeeze roll and following squeeze roll, and last squeeze roll is connected with power set, and last squeeze roll is connected by lazy-tongs with following squeeze roll.

The beneficial effects of the utility model are: owing to be connected synchronously between the following squeeze roll of this rinse bath and the last squeeze roll, therefore, following squeeze roll can be realized active rotation, and rotates synchronously with last squeeze roll, do not have relative velocity between squeeze roll and the band steel, realize sending the synchronous extruding of band steel to.The utility model has overcome the following squeeze roll of existing rinse bath because the technical problem of easily skidding between unavoidable band steel of passive rotation and the following squeeze roll, and avoided time squeeze roll to being with the scuffing of steel, simultaneously, the effect of cutting reduces the band steel to the traditional method of indicating the pronunciation of a Chinese character of squeeze roll, thereby can effectively protect the working face of squeeze roll, thus improve squeeze roll service life; Because the working face of squeeze roll has obtained effective protection, and the squeeze roll function is not fully exerted, extract effect and also improve thereupon.The utility model used device is few, improvement is effective, is particularly suitable for strip steel Zn-plating and color coating unit and uses.
