[0020] The tensioning adaptive adjustment component 7 includes an installation box 70 screwed on the bottom of the workbench 1, and an adjustment sprocket 71 is movably installed inside the installation box 70. At the same time, the rotating shafts 73 on both sides of the adjustment sprocket 71 are movably installed on the tensioning plate 741 through bearings, and the bottom of the tensioning plate 741 is welded to the surface of the tensioning block 74.

[0021] Working principle: The motor 6 drives the chain 4 to rotate through the driving sprocket 5 and the chain 4, and the adjusting sprocket 71 is engaged with the chain 4. At this time, the spring 80 is in a compressed state, and the elastic force of the spring 80 is in a balanced state with the tension of the chain 4. When the chain 4 becomes loose, the force acting on the adjusting sprocket 71 is reduced, and the compressed spring 80 is released, so that the adjusting sprocket 71 moves outward, compresses the loose chain 4, and tensions the chain 4, thereby realizing adaptive adjustment of the chain 4 without manual intervention, thereby avoiding separation between the chain 4 and the driven sprocket 3 and the driving sprocket 5.

[0022] As a preferred implementation, the adjusting sprocket 71 is installed in the middle of the chain 4, and the adjusting sprocket 71 is meshed with the chain 4, and the adjusting sprocket 71 is a lifting structure.

[0026] When the tension acting on the adjusting sprocket 71 decreases, it means that the chain 4 becomes loose. At this time, the spring 80 is released, pushing the moving block 78 to move inward, and the angle between the connecting piece 75 and the connecting rod 76 increases, so that the adjusting sprocket 71 moves upward, and the chain 4 is tensioned to ensure the stability of the chain 4 during operation and prevent it from detaching from the driven sprocket 3 and the driving sprocket 5.
