Description

High wear-resisting conveying chain

Technical Field

The utility model relates to the technical field of chains, in particular to a high-wear-resistance conveying chain.

Background

The large roller in the dough making mechanical conveying chain in the food industry is generally made of metal, the two chains are used in left and right matching, the outer chain link is provided with an elongated pin shaft, and the connecting rod is sleeved on the elongated pin shaft for fixing.

When in conveying, the outer surface of the large roller on the chain is contacted with the guide rail to roll forward, and the inner hole round surface and the sleeve rotate relatively. The local abrasion appears on the outer surface of the sleeve, and when serious, the contact between the chain plate and the guide rail can generate sliding friction, thereby increasing the running resistance of the chain and generating obvious noise. When the sleeve is worn, the firmness of the chain links is reduced, and the abrasion, elongation and failure of the chain are increased. Dust generated by abrasion is easy to pollute food.
