Description

Technical Field

[0001] The utility model relates to the field of chain conveyors, in particular to a chain protection mechanism of a chain conveyor. Background Art

[0002] Chain drives are most commonly used to transmit power between two parts that are a long distance apart, but they can also be used over short distances, and they are one of the five most common methods of mechanical power transmission along with couplings, gear drives, belt drives, and power screws.

[0003] The chain needs to be maintained during operation, so the chain protection mechanism of the chain conveyor is needed.

[0004] After searching, the applicant found that a Chinese patent disclosed "a mechanism to prevent reverse dust transportation", and its publication (announcement) number is "CN216637917U". This patent mainly prevents dust and the like from entering the machine and causing damage by installing two dustproof plates, thereby extending the service life of the mechanism. When transporting workpieces, the entry of dust is well prevented, so that the transportation is not stuck. In addition, a non-return assembly is used. When the workpiece table passes, the baffle on the non-return assembly is pressed down. After the workpiece table passes, the pressure plate on the non-return assembly returns to its original position due to the lack of gravity. When the workpiece table suddenly retreats, the block on the non-return assembly will block the workpiece table to prevent the workpiece table from suddenly retreating and reverse transportation. Four rubber baffles on the workpiece table can well protect The workpiece will not be damaged due to the shock force. This not only ensures the smooth transportation of the workpiece and protects the integrity of the workpiece, but also greatly prolongs the service life of the mechanism, reduces the probability of maintenance, reduces labor intensity, and thus greatly improves production efficiency. However, during the operation of the traditional chain conveyor, it is necessary to manually apply a layer of lubricating oil to the surface of the internal chain to ensure the operation of the chain, which is time-consuming and labor-intensive, increases the workload of workers, and thus increases labor costs. In addition, during the operation of the chain conveyor, due to the high dust in the air, the dust and lubricating oil will mix to produce sludge. When a large amount of sludge is produced, it is easy to cause equipment damage and requires manual cleaning. The procedure is cumbersome and reduces the practicality of the equipment.
