Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a conveying structure of a single-layer heavy-duty double-chain conveyor line. Background Art

[0002] The double-speed chain is a device used to convey materials during the production and processing process. Its main principle is to install rollers inside the transmission chain. When in use, the rollers move forward along with the transmission chain. At the same time, the rollers contact the friction pads at the bottom, so that they roll while sliding, and the workpiece contacts the upper surface of the rollers, thus achieving the double-speed effect.

[0003] However, in actual use, the transmission effect of the double-speed chain is greatly affected by the frictional resistance of the rollers and the friction pads in contact with the rollers. When the materials on the top are heavy, if the resistance between the rollers and the friction pads is too small, the rollers will slip and the double-speed transmission cannot be achieved. This situation will be more obvious after the rollers and friction pads have been used for a long time. And the current solution is that the entire double-speed chain needs to be disassembled before replacing the rollers and friction pads, and the assembly is rather troublesome. Therefore, a conveying structure of a single-layer heavy-duty double-chain conveyor line is provided to solve the above problems. Summary of the Utility Model
