Novel block chain for conveying system for roving-spinning units

The invention discloses a novel block chain for a conveying system for roving-spinning units. The novel block chain comprises a conveying rail, a chain bar and multiple blocks. The blocks are assembled in the conveying rail, a chain bar hinging base is arranged on the lower portion of each block, and the chain bar hinging bases are fastened with the chain bar through connection components. An ingot support is connected with the bottom end of each block and is in a symmetrical shape, and the middle of each ingot support is in pin connection with the corresponding block. An ingot component is connected to each end of each ingot support. According to the novel block chain, the transport capacity is improved through a means of increasing the bearing number of the block chain, and accordingly the conveying requirement of normal production turnover of workshops is met; meanwhile, the number of relevant parts such as the conveying rail and a motor for the system is decreased to a large extent, and the cost input of the conveying system for the roving-spinning units is effectively lowered.
