Belt conveyor is use to continuous or intermittent movement to transport a variety of different weight of goods, not only can transport a variety of bulk materials, but also can transport a variety of cartons, packaging bags and other small weight of a single piece of goods, it have a widely application,the main components of belt conveyor include: conveyor belt, idler, pulley, conveyor idler bracket, driving device, belt cleaner, protection device and unloading device etc. Conveyor Idler bracket is one of the important part of belt conveyor. EXCT will introduce the importance of conveyor idler bracket to belt conveyor In this paper. Conveyor idler bracket is a kind of auxiliary accessories related to belt conveyor. Its application makes conveyor idler play a better role in the belt conveyor.It strongly supports the weight of rollers, conveyor belts and goods.During the application of idlers, attention should be paid to the adjustment of conveyor idlers frame. A good adjustment of idlers can effectively prevent the deviation of the conveyor belt.Thus, it will not cause leakage and abnormal wear of related equipment, such as bend idler and drive roller, which will lead to the reduction of production capacity and efficiency.So the quality of conveyor idler bracket is very important for conveying machinery. From the above description we have realized the importance of Conveyor idler bracket to conveying machinery, then we should have a good understanding of today's protagonist - conveyor idler bracket.It is a combination of bracket, support, pin shaft, fuselage, roller and limit block and fastener.The base support of the conveyor roller bracket is connected with the upper end of the fuselage with solid pieces. Most of the time, stainless steel pipe fittings are used for connection.On the deflector supporting bracket, there is a clamping groove for rotating about the pin shaft, the idler is installed in the clamping groove of the deflector supporting bracket, and a limit block for controlling deflection Angle is set on the deflector supporting bracket.A pin axis is provided on the support or fuselage for the deflecting roller bracket to rotate about it. When the fastener is removed, the deflecting roller bracket can rotate about the horizontal fixed pin axis at a certain Angle under the control of the limit block.
