The belt conveyor is light and reasonable in structure and can be moved at any time. It can be widely used in conveying operations in industries such as light industry. If you want to have a good effect during use, you must install the equipment correctly. When installing the belt conveyor, you need to pay attention to the following issues: pay attention to the assembly dimensions of the fuselage components and maintain the straightness of the whole machine. . Tighten the bolts when installing the bolt fasteners. When making a tape joint, align the centerline of the belt at both ends to prevent the tape from drifting.
The driving roller is one of the main accessories of the belt conveyor, and it plays an important role in the equipment's conveying efficiency, use effect, and reliability. The surface of the belt conveyor driving roller has two types: smooth surface and rubber surface. The purpose of the rubber surface is to increase the friction coefficient between the driving roller and the conveyor belt, and reduce the wear of the roller. When the power is not large and the environment humidity is small, a smooth surface roller can be used. When the environment is humid and the power is large and it is easy to slip, a rubber surface roller should be used as the driving roller.
When the device is installed, the method of increasing the friction and the wrapping angle between the conveyor belt and the driving roller can be used to ensure that the necessary traction is obtained. When using single drum drive; the wrapping angle can reach 180 ° -240 °; when using double drum driving, the wrapping angle is about 360 ° -480 °. The use of double-roller transmission can greatly improve the traction of the belt conveyor, so it is often used, especially when the transport length is relatively long, generally using a double-roller drive.
Belt conveyor supplier china believes that the support of a belt conveyor has a great relationship with its performance:
1. Roller bracket: It is used to install the transmission roller and the roller, and it can withstand the tension of the belt conveyor belt. There are mainly four types according to the application. The height is suitable for the conveyor.
(1) Head drive roller bracket: Conveyor for head drive and head unloading, suitable for bandwidth 500 ~ 1400mm, generally equipped with redirecting rollers as booster wheels, and the surrounding angle of the driving roller is 190 ° ~ 210 degree.
(2) Tail redirecting drum bracket: It is used for the tensioning device located in the middle of the conveyor. It is suitable for 500 ~ 1400mm bandwidth and has a protective cover. Generally, it can be installed as a redirecting drum for increase wheel.
(3) Head redirecting roller bracket: The probe roller bracket is used to drive the roller set in the middle, and the head roller is only used for redirecting and unloading the conveyor, suitable for a bandwidth of 800 ~ 1400mm.
(4) Middle drive roller bracket: Dedicated to the conveyor equipped with a drive roller in the middle, suitable for a bandwidth of 800 ~ 1400mm, one drive roller and one redirecting roller can be installed as an increase wheel. When used in pairs and symmetrically installed, It can also be used in the middle of double-drum transmission, with a wrap angle of 200 degrees or more.
In addition, in order to meet the requirements of some special type conveyors, there is a modified roller hanger that can be located in the middle, and the applicable bandwidth is 500 ~ 1400mm.
2.Middle frame and outriggers
In order to ensure the rigidity of the middle frame of the big angle belt conveyor, the middle frame is added with a crossbeam to make the middle frame itself as a whole. It is designed in two types: 6000mm standard section and 3000 ~ 6000mm non-standard section.
3.Tighten the device frame
a. Screw tensioning device frame: divided into 5 types according to the angle range. Need to choose the appropriate screw tensioner bracket according to the belt conveyor inclination.
b. Vertical tensioning device frame: The bracket is designed according to the total height of 5000mm. Beyond this range, check the strength and stiffness of the bracket.
c. Car-type tensioning device frame: there are two types of standard structure and pulley. Among them, the trolley-type tensioning conveyer with a pulley is used in the structure where the structure around the conveyor is used and the weight is supported by the pulley. Non-standard car-type tensioning device frames need to be suspended by redirecting pulleys and towers, or used for winch-type tensioning devices.
