Description

Technical Field

[0001] The utility model relates to the field of metal plate straightening, in particular to a metal plate straightening device. Background Art

[0002] Metal sheets are thin, flat sheets of metal formed by industrial methods. During the processing, metal sheets need to be cut and straightened. The straightening process is mainly carried out by conveying rollers to the straightening rollers, and finally the metal sheets are pressed straight by the straightening rollers to ensure the flatness of the metal sheets.

[0003] However, there is often dust and impurities on the surface of the metal plate after cutting. If the metal plate with dust and impurities on the surface enters the straightening roller without being cleaned, the straightening roller will roll the dust and impurities together with the metal plate. At this time, the rolled dust and impurities will be embedded or more firmly adhered to the surface of the metal plate, which will cause the surface of the metal plate to become bumpy and affect the straightening effect.

[0004] Therefore, it is necessary to invent a metal plate straightening device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0007] Based on the above characteristics: when the conveying roller rotates, the rotating shaft in the middle of one of the conveying rollers is connected to the transmission assembly, which is convenient for driving the transmission assembly to rotate synchronously. At the same time, the transmission assembly can drive the movable tooth plate to move back and forth left and right. The movable tooth plate is limited by the guide rail, which is convenient for driving the dust collection assembly and the cleaning brush to move synchronously. At this time, the cleaning brush can clean the dust and impurities on the surface of the metal plate, and the dust collection assembly can absorb the dust and impurities to prevent the dust and impurities from adhering to the surface of the metal plate when the metal plate enters the middle of the straightening roller for straightening. The positioning assembly can position and convey both sides of the metal plate according to the size of the metal plate to prevent the metal plate from moving left and right when being cleaned by the cleaning brush.

At this time, the adsorbed impurities and dust will be adsorbed by the suction fan through the air distribution duct and the connecting hose. Finally, the suction fan will discharge the adsorbed impurities and dust into the dust collection box for collection.

[0018] Preferably, the positioning assembly comprises a telescopic cylinder and a frame plate installed at one end of the telescopic cylinder, a groove is provided in the middle of the frame plate, and a positioning roller is installed inside the groove.
