In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a high wear-resisting pickling roller for steel sheet, includes the mount, mount inner chamber symmetric rotation is equipped with roller, lower roll, mount right side fixed mounting has driving motor, driving motor output shaft and lower roll are connected, the spout has been seted up to mount inner wall symmetry, go up the roller both ends and pass through slider and spout sliding connection, go up and be connected through the telescopic link between roller both sides and the mount roof, it all includes the roller to go up roller, lower roll, evenly set up flutedly on the roller, all fixed wear-resisting strip that is equipped with in the recess, the fixed plate that is equipped with in roller both ends.

Further, the fixed installation ear that is equipped with in mount bottom, go up the roller both ends and rotate through bearing and slider, telescopic link and be connected, go up the roller, roll shaft length is the same down.

Furthermore, the telescopic link comprises fixed loop bar, telescopic strut, expanding spring is located fixed loop bar, telescopic strut top imbeds in the fixed loop bar and is connected with expanding spring.

Furthermore, the bottom of the wear-resistant strip is fixedly provided with a clamping strip, the clamping strip is positioned in the groove, the cross sections of the clamping strip and the groove are trapezoidal, and the surface of the wear-resistant strip is provided with anti-skidding textures.

Furthermore, locating holes are formed in the two ends of the wear-resistant strips, locating rods are evenly and fixedly arranged on the fixing plate, and the locating rods are inserted into the locating holes.

Furthermore, the two ends of the inner cavity of the roller are symmetrically and fixedly provided with limiting blocks, and the fixing plate is fixedly provided with limiting grooves.

The invention has the beneficial effects that:

1. by arranging the telescopic rod, when the steel plate conveying device is used, a steel plate is conveyed between the upper roller shaft and the lower roller shaft, and the telescopic rod can extrude the upper roller shaft downwards all the time, so that the pressure between the two roller shafts is ensured, and the steel plate can be normally conveyed;

2. through setting up wear resistant strip, evenly set up wear resistant strip on the roller, increase the wearability of roller, the steel sheet is prevented to appear skidding when carrying, and wear resistant strip is pieced together simultaneously, when the roller surface is impaired, can dismantle solitary wear resistant strip and get off to change, conveniently maintains.
