Composition of roller:

Roller in the composition of two types, refers to no power and drive. For the non-powered conveyor roller will be called the free roller, is composed of the barrel, shaft core, deep groove ball bearing and bearing mounting frame, in use for auxiliary rolling use, no power itself, by external rolling.

Drive roller is generally referred to as the built-in motor electric roller, here we should also note that it is with sprocket wheel, synchronous belt wheel can be driven by the reducer motor roller. The structure is basically the same as that without power, except that a motor is built in or a sprocket wheel or synchronous belt wheel is installed outside and other parts that can be driven by a decelerating motor.

Roll selection steps:

In the selection of rollers, attention should be paid to the difference in weight, the diameter and length of rollers should be selected, and the length of rollers should also be paid to the production according to the requirements of users, generally the width of goods +50mm. There are different kinds of rollers in our company which can be used for conveying materials of different weight, length and requirements. The use of stationary environment should choose the right kind of roller, such as the wet environment should choose stainless steel or plastic type of roller.

In the selection of rollers, attention should be paid to the turning radius when there is a turning roller table, so as to ensure the smooth delivery of materials. In order to ensure the balanced delivery of goods, in this regard, it is necessary to pay attention to the three rollers in contact with the delivery at all times. After that, it is necessary to add pallets for the soft bag packaging.

Classification of rollers:

According to whether there is power or not, there are two types of power roller: straight roller and cone roller. Later also should pay attention to according to the driving effect, the power roller can be divided into two kinds of fixed and cumulative; Next, we should pay attention to the driving effect, the power roller can be divided into circular belt drive (groove) flat belt drive (friction belt) and chain drive (chain theory) three categories; According to bearing types, special precision bearing and special stamping bearing, bearing number includes steel and engineering plastic.
