Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a metal plate roller conveyor with multiple limit mechanisms. Background Art

[0002] Metal sheets are plates or parts made of metal materials through different processes. The processing techniques of metal sheets are diverse, mainly including stamping, bending, sheet metal production, spraying, painting, transfer printing, etc. In the process of processing metal plates, they need to be manually transported to a designated location and then processed accordingly. Manual transportation is time-consuming and labor-intensive, and the processing efficiency of the plates is not high.

[0003] In order to overcome the above-mentioned defects, prior art 1 (publication number: CN118322296A, Chinese patent with publication date of 2024-07-12) is a multi-layer hot press with a plate conveying mechanism: a base, a loading mechanism and a feeding mechanism are connected to the base, the feeding mechanism includes a mobile frame, and a multi-layer material rack is fixedly connected to the mobile frame; the loading mechanism includes a lifting frame, and a liftable lifting frame is connected to the lifting frame. The plates are stacked and placed on the lifting frame, and a fixed frame is fixedly connected above the lifting frame, and a pushing mechanism is connected to the fixed frame. A lifting cylinder is installed on the fixed frame, and the pushing mechanism includes a connecting frame, and a pushing cylinder is fixedly installed on the connecting frame. The pushing cylinder is connected to a pushing seat, and a liftable lifting plate is connected to the pushing seat, and a plurality of hook rods are fixedly connected to the lifting plate; the plates stacked on the lifting frame are pushed one by one to the corresponding material racks through the pushing mechanism, thereby improving the conveying efficiency of the plates.

[0004] There is also prior art 2 (publication number: CN113003219B, Chinese patent with publication date of 2024-06-18) a plate conveyor with a suction cup structure. By arranging connecting columns, suction cups, square tube units, elastic column units and lifting and adjusting plate units on the main plate, the purpose of flexible and adjustable distance between the two rows of suction cups is achieved, ensuring that the suction cup plate conveyor can transport plates of different sizes. The effective suction area composed of the two rows of suction cups is flexibly adjustable. When sucking relatively large plates, the suction cups can be appropriately adjusted outward, and when sucking relatively small plates, the suction cups can be appropriately retracted. All suction cups are adjusted to expand outward or retract inward synchronously to ensure that the adjustment operation is simple, convenient, accurate and fast, and the suction cup position is not easy to loosen after adjustment. The entire suction cup structure has high stability and compact structure, which is convenient for disassembly and maintenance, and does not affect the normal plate handling action.

[0005] Although the existing technologies 1 and 2 can perform mechanized handling of metal plates and improve handling efficiency, they cannot limit the position of the plates during handling. The plates are prone to displacement and tilt during transportation, and thus fall from the conveyor belt, which has certain limitations.
