The roller conveyor is used in assembly line work, a device that applies not only to the delivery of all kinds of boxes, bags and trays, and other goods, but also can be used for the delivery of bulk materials and small items, as well as irregular items, with bear a greater impact load, the function of conveying a single piece of heavy weight materials. 
 (1) the scope of application 
 Roller conveyor at the bottom is flat transportation of goods, mainly due to the drive pulley, rack, stand, drive unit and other components of its unique structural characteristics of the decision it has a transmission volume, speed, running light and can be achieved multi-species line transmission characteristics of the shunt. 
 2 structure 
 Conveying the layout of the form is divided into horizontal, inclined conveyor and turning conveyor into power, no power, electric rollers, etc. from the drive form. 
 3 sizes 
 Standard turn of the roller conveyor turn roller line radius 300,600,900,1200 mm, etc. Of course, other specifications according to different needs; the width of the roller conveyor according to the needs of production; used in the straight section of roller drum diameter 38 , 50,60,76,89 mm; taper of the turning drum to design conveying the weight of the object, shape, size, line speed. 
 Dynamic way: the deceleration of a motor drive, the roller drive. 
 5 Speed ??mode: Frequency Control, Continuously Variable. 
 (6) Transmission: single sprocket, double sprocket, O-belt, flat friction drive belt, timing belt, etc.. 
 Meanwhile, due to the different needs of the roller conveyors in custom requirements, so the custom before, be sure to identify related technical parameters. 
 Conveyor length, width and height of the object; 
 (2) transport from the bottom of the situation; 
 (3) the weight of each conveyor unit; 
 The conveyor is no power or motor driven type; 
 Whether the requirements of the special working environment (such as: humidity, high temperature, chemicals, impact, etc.).
