Belt turning mechanism, belt conveyor comprising belt turning mechanism and belt turning method of belt conveyor

Abstract

The invention provides a belt turning mechanism, a belt conveyor comprising the belt turning mechanism and a belt turning method of the belt conveyor, the belt conveyor comprises a first belt pressing roller set, a plurality of belt turning devices and a second belt pressing roller set which are arranged in sequence in the running direction of a rubber belt, and each turning device is provided with a belt turning restraining assembly. And the adhesive tape turning section is turned over by 180 degrees through the tape turning device in a segmented mode, and then adhesive tape turning is completed. Therefore, the use occasions of the belt turning device are increased, and the abrasion of the belt turning device to the belt is reduced.

Description

technical field [0001] The invention relates to the field of conveyors, in particular to a belt turning mechanism, a belt conveyor including the same and a belt turning method thereof. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in mining, metallurgy, electric power, ports and other industries. For long-distance conveyors, after the belt conveyor unloads the material, the bearing surface of the conveyor belt will adhere to the part. Residual material, on the one hand, the residual material will stick to the lower roller, which will not only increase the wear of the roller skin, increase the operating burden of the conveyor, cause the belt to deviate, and at the same time cause the material to be scattered along the way, polluting the transportation route. After the belt conveyor unloads the material, the tape is turned over, so that the tape bearing surface of the return section turns to the upper part, which can solve the prob...

Problems solved by technology

[0003] At present, there are the following types of belt turning devices: pinch roller type, vertical belt turning type, semi-circular tube type, etc., but there are some disadvantages, such as the pinch roller type and vertical direction turning belt type, the turning height of which is higher than the length of the belt itself. It is not conducive to the use of venues with limited space; CN203558422U discloses a belt turning device for a circular tube belt conveyor, which consists of two sets of lower parallel idler rollers and two sets of upper parallel idlers independently installed on a fixed intermediate frame or frame. The roller group and three sets of hexagonal idler roller groups are composed to complete the belt turning

However, in order to eliminate the excessive deformation of the belt edge caused by excessive restraint during the belt turning process, a longer belt turning distance is required to offset the belt edge deformation caused by being restrained, so as to reduce the belt edge stress and wear the conveyor belt Reach the normal state, so take up a lot of space
