[0002] A sprocket is a mechanical transmission element that consists of slots, holes and teeth. The function of a sprocket is to transfer power from the engine's power source to other parts of a machine or equipment. There are two definitions of a sprocket: one is a wheel with cog-type sprocket teeth that is used to mesh with accurately pitched blocks on link chains and cables; the other is a solid, spoked gear that meshes with a roller chain to transmit motion.

[0003] The patent application with publication number CN206662555U discloses a sprocket monitorable limit adjustment module and a sprocket device for a laser cutting machine exchange table, which can facilitate the installation of the chain and can also adjust the tension of the chain between the master and slave sprockets according to the transmission needs to achieve accurate and stable switching of the two material receiving tables on the exchange workbench; the sprocket seat can be driven to move by turning the adjusting bolt with a wrench, and the position of the sprocket seat can be fixed by tightening the adjusting nut after adjustment, and the influence of the mechanical clearance can be weakened, and the impact resistance is also improved; the sliding part at the lower end of the sprocket seat is arranged in the slide groove on the base, the support of the sprocket seat is stable, and the sliding guiding effect is also good; and the U-shaped support part at the upper end of the sprocket seat supports the slave chain through the pin shaft The wheel can provide good protection for the slave sprocket under the premise of compact structure. The guide pressure plate can press the sprocket seat into the slide groove of the base to prevent it from tilting. On the other hand, it can also guide the movement of the sprocket seat to avoid the shaking of the slave sprocket during rotation. The two ends of the pin shaft of the slave sprocket are fixed by shaft covers, which is convenient for disassembly and assembly. The slave sprocket is set on the pin shaft through bearings. The inner and outer rings of the bearing are fixed by shaft retaining springs and hole retaining springs respectively to avoid the movement of the bearing on the pin shaft and eliminate the axial movement of the slave sprocket. The maintenance of the slave sprocket is also convenient, and the chain tensioning force can be adjusted to ensure the continuous and stable operation of the exchange table. The chains on both sides can be driven to move synchronously by one motor to ensure the reliability of the movement of the material receiving platform on the exchange table.

[0004] The device proposed in the above-mentioned comparative document needs to regularly check the sprocket device during use, or the chain on the sprocket device falls off before it can be discovered that the wheelbase between the master and driven sprockets needs to be adjusted. The sprocket device cannot be monitored at any time to automatically adjust the sprocket wheelbase and then tighten the chain. The above-mentioned comparative document needs to stop the sprocket device when tightening the chain. It cannot be adjusted during use, and it cannot limit the chain being adjusted.
