Description

Technical Field

[0001] The utility model relates to the field of production and processing of egg trays, in particular to a chain-driven tensioning device for conveying egg trays. Background Art

[0002] Egg trays are a type of packaging tool used to hold eggs such as chicken eggs and duck eggs. Their main function is to reduce shock and facilitate the transportation and carrying of eggs. Egg trays can be divided into pulp egg trays and plastic egg trays according to the different materials used. In daily life, pulp egg trays are more common and have less pollution to the environment.

[0003] After the egg trays are produced, they need to be transported by conveyor belts, and conveyor belts are usually chain conveyor belts. This is mainly because the egg trays themselves have a high temperature after production, so belt transmission is rarely used. In most cases, chain transmission is used, and the transmission belt has a grid structure to facilitate cooling of the egg trays during transmission.

[0004] However, since the egg trays are conveyed by chain drive, the chain is prone to skipping or slipping on the sprocket during transmission, causing the conveyor belt to stop. This not only affects the transportation of the egg trays, but also requires a lot of labor to reinstall the chain on the sprocket, affecting the production of the egg trays. Utility Model Content

[0005] In order to reduce the risk of chain jumping or slipping on the sprocket during rotation, the utility model provides a chain drive tensioning device for egg tray conveying, which uses a first tensioning wheel to statically tighten the chain and a second tensioning wheel to dynamically tighten the chain, thereby improving the stability of the chain during transmission and reducing the risk of chain jumping or slipping during transmission.
