Abstract

The invention discloses padding equipment for dyeing and finishing cloth, and relates to the technical field of cloth padding. The invention comprises a U-shaped frame and an upper roller, wherein the upper roller is rotatably arranged on the opposite inner wall of the U-shaped frame, and two guide rollers are rotatably arranged on the U-shaped frame. According to the scheme, through ingenious arc-shaped movement mechanism design, the problem of high-precision linear micro-displacement control between the lower roller and the upper roller is converted into low-precision arc-shaped displacement control between the lower roller and the upper roller, so that the distance between the lower roller and the upper roller can be adjusted in another mode, the stroke amplification principle is skillfully applied in the design, when the pressure adjusting mechanism drives the movable piece to move along an arc track for a longer arc distance, the distance variation between the lower roller and the upper roller, which is directly brought by the pressure adjusting mechanism, is very small, and therefore, the complex control objective can be achieved through a simple mechanical structure, namely, the distance between the lower roller and the upper roller can be controlled through lower driving precision.
