Description

Technical Field

[0001] The present application relates to the technical field of lifting devices, and in particular to a lifting mechanism of a grid bowl stacking machine. Background Art

[0002] The stacking machine is an automated equipment developed and designed for the stacking process of multi-layer saggers for lithium batteries, rare earth materials, etc. Its main purpose is to automatically stack the saggers into multiple layers, and it can also meet the process of saggering the materials before stacking. The stacking machine adopts a vertical lifting stacking design, which is convenient and flexible. There is no external force on the sagger during the entire operation process. It is safe and reliable and can effectively prevent the sagger from being damaged.

[0003] At present, the lifting mechanism of the existing stacking machine is achieved by arranging synchronous lifting cylinders on both sides of the sagger. After being used for a long time, the lifting of the cylinders will become asynchronous, causing the sagger to overturn and causing serious wear of the cylinders. When stacking saggers of different heights, the lifting height of the cylinders needs to be adjusted manually, which is more troublesome to operate. Utility Model Content

Then the lifting device is involved, and the driving motor 31 drives the screw rod 32 to rotate, so that the ball nut 33 sleeved on the screw rod 32 slides along the screw rod 32, thereby driving the sliding plate 4 to slide along the guide rod 22, and the sliding plate 4 drives the lifting frame 5 to move up and down, and the lifting frame 5 is against the bottom of the sagger to realize the lifting and lowering of the sagger; the action of the sliding plate 4 on the guide rod 22 prevents the sliding plate 4 from deflecting or overturning, ensuring that the sliding plate 4 slides smoothly, and the lifting frame 5 is an integral structure, and the sagger is subjected to the balanced force of the lifting frame 5, so that the lifting frame 5 steadily lifts the sagger to stack the sagger; after the stacking is completed, the cylinder 72 drives the blocking plate 73 to descend, and the conveying device transports the stacked saggers out.
