[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the design of an adjustment mechanism, activates a hydraulic rod to drive the balancing mechanism downwards according to the thickness of the cold-rolled strip. The balancing mechanism synchronously drives the frame to descend, reducing the distance between the first and second pressure rollers and their corresponding conveying rollers. The first pressure roller, in conjunction with the front side, completes the initial cold rolling. After the strip is pressed into a thin sheet, it is conveyed into the feed port of the degreasing mechanism. Alkali solution or organic solvent is introduced into the corresponding sponge strip through a conduit. The upper and lower sides of the thin sheet are coated with alkaline solution or organic solvent for degreasing, removing grease and oil stains from the surface of the thin sheet. The coated thin sheet is then fed between the second pressure roller and the corresponding conveying roller, where the second pressure roller and the conveying roller complete the secondary cold rolling. A matching set of hydraulic rods adjusts the distance between the two sets of cold rolling mechanisms, reducing operating costs. At the same time, a V-groove is formed to create a recess for the corresponding position of the degreasing mechanism, ensuring that the feed port of the degreasing mechanism aligns with the feed path of the thin sheet, allowing for adaptation without adjustment.

[0016] 2. This utility model also incorporates a balancing mechanism. When the hydraulic rod drives the horizontal plate to rise and fall, the horizontal plate synchronously drives the insert block. The insert block's crank part, in conjunction with the slot, drives the frame to rise. When the horizontal plate presses down on the upper side of the frame, it causes the frame to fall. By increasing the contact surface of the horizontal plate, the downward pressure is reduced, thus reducing the stress on the frame and preventing damage. At the same time, multiple support points ensure the stability of operation. Attached Figure Description
