What are the material and diameter of the rollers of the roller conveyor?

The rollers of roller conveyors are usually cylindrical, and there are mainly sub-drive and slave-drive. Roller type conveyors can be used in assembly line operations, rotary screen printing machines, digital printers, conveyors, and papermaking. The rollers of roller conveyors are generally made of seamless steel pipes for seam splicing. In addition, different materials can be used according to different processes. Commonly used materials are aluminum alloy 6061T5, 304/316 stainless steel, etc.

After the roller is formed, for the needs of anti-rust, anti-corrosion, wear resistance and support, it also needs surface treatment or coating such as painting, galvanizing, TEFLON spraying , rubber, chrome plating, ceramic spraying and oxidation and other processes. Classified according to size, there are large rollers such as papermaking machinery (the length can reach more than 10 meters. The diameter is more than 1500M), and there are small ones such as flat rollers used on belt conveyors on automatic assembly lines (usually 1 meter long). within), the diameter is 159MM.

Drum diameter selection: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm. The principle of determining the diameter of the drum is that when the tensile stress of the endless loading conveyor belt is large, the additional bending stress should be smaller; on the contrary, when the tensile stress is small, a slightly larger bending stress is allowed, and a smaller drum can be selected. diameter.

The material choices of roller loading conveyor are: carbon steel galvanized, steel carbon chrome plating, carbon steel lagging, aluminum alloy, stainless steel, ABS, etc. Roller type selection: unpowered rollers, single-chain rollers, double-chain rollers, '0' belt rollers, tapered rollers, grooved rollers. Roller fixing method: spring press-in type, internal tooth shaft type, full flat tenon type and through shaft pin hole type.

There are a wide variety of which are scientifically tested to have positive effects on the ability to container loading machine. container loading machine flexible conveyor system is one of them.
