In the prior art, chain conveying, especially large-load-bearing chain conveying, mostly adopts roller conveying chains, such as standard long-pitch roller conveying chains, double-pitch roller conveying chains, and the like. The standard conveying chains are compact in structure, rollers in the standard conveying chains are sleeved on the sleeves in a large clearance mode, and the rollers are meshed with the chain wheels to transmit power, roll on the guide rails and bear conveying loads. However, these standard chains have sliding friction between the bushings and the rollers, and when the load is large and the conveying speed is high, the bushings are easily worn, and the service life of the chain is shortened. At the end of the 20 th century, a paper mill has a conveying chain with a standard needle bearing arranged between a sleeve and a roller, and the chain sleeve and the roller have rolling friction, so that the friction coefficient is small, the sleeve is not easy to wear through, the service life of the chain is prolonged, the power of a speed reducer of conveying equipment can be reduced under the condition of conveying the same load, and the purpose of reducing energy consumption is achieved. However, the chain has the disadvantages that the needle roller bearing is not easy to install, the tolerance between the outer circle of the sleeve and the inner hole of the roller is difficult to achieve, and the needle roller bearing is easy to be stuck due to dust accumulation in a paper mill. In addition, with the rapid development of the paper making industry, in order to reduce the production cost, improve the working efficiency and seize the market share, the paper making mill often puts higher requirements on the transportation and packaging of paper products, such as: the paper rolls required to be conveyed are heavier and heavier, the diameters of the paper rolls are larger and larger, the conveying speed is higher and higher, and the like. Therefore, the technical personnel in the field need to solve the problems of large bearing capacity, long service life, convenient installation and maintenance and adaptation to the requirements of paper mills.

Secondly, in the prior art, the paper mills are equipped with special production lines, one of which can only be used for horizontal transport packaging of webs (cylindrical shape) and the other of which can only be used for transport packaging of stacks of flat sheets (rectangular parallelepiped shape). However, due to the requirement of special processes, paper mills often need some conveying and packaging equipment to convey both the packaging paper roll and the packaging flat paper pile, so that the conveying chains used for the equipment have the functions of conveying the paper roll and the flat paper pile.
