Description

Feeding mechanism, conveying device and feeding method for wide and thin metal plates Technical Field The invention relates to the technical field of plate conveying equipment, in particular to a wide and thin metal plate feeding mechanism and a conveying device. Background In the metal processing industry, the plate is used as a basic and important planar material and is widely applied to the fields of automobile manufacturing, aerospace, architectural decoration and the like. The wide and thin metal plates are usually processed through a rolling process, are mostly rectangular and smooth in surface, the plates to be processed are usually piled up together so as to be convenient to store and transport, and based on the characteristics of the products and the piling mode, air between adjacent plates is easily extruded and closely adsorbed together, so that the separation difficulty is remarkably increased. When wide thin metal plates are conveyed one by one in the processing process, a feeding mechanism usually utilizes a plurality of suckers to adsorb and fix the plates, and then the upper adjacent plates and the lower adjacent plates are separated through strong traction force, so that the feeding mode has obvious defects. Specifically, the forced separation of the closely adsorbed plates has high power requirements on the feeding equipment, so that the energy consumption is greatly increased; in the case of wide and thin metal plates (such as aluminum plates, aluminum-magnesium-manganese plates, color-coated steel plates and the like) with small thickness and low strength, the high-strength adsorption force and traction force are very easy to cause plastic deformation such as crease, concave-convex and the like of the whole or part of the plate, so that the flatness and the subsequent processing quality of the plate are seriously affected. In view of the foregoing, there is still a significant disadvantage in the separation efficiency, energy consumption control, sheet protection and conveying stability of the conventional wide and thin sheet metal feeding device, and there is a need for a feeding and conveying solution that can achieve reliable separation of single sheet with low consumption and no damage.
