Width-adjustable carrier roller

Abstract

The invention discloses a width-adjustable carrier roller, and relates to the technical field of carrier rollers. The carrier roller comprises a bottom plate, a bolt column, a middle carrier roller assembly, a left carrier roller and a right carrier roller; two T-shaped grooves are formed in the upper surface of the bottom plate; T-shaped blocks are glidingly matched in the T-shaped grooves; two first mounting plates are fixed to the upper surface of each T-shaped block; two groups of vertical plates are fixed to the upper surface of the bottom plate; a sliding groove is formed in one side ofeach vertical plate; limiting plates are fixed to the outer side surfaces of each group of vertical plates; a lifting column is glidingly matched between each group of vertical plates; two vertical plates are fixed to the upper surface of the bottom plate; the two ends of the bolt column penetrate through the two vertical plates correspondingly; threaded cylinders are fixed to the inner side surfaces of the two T-shaped blocks; and the two ends of the bolt column are located in the two threaded cylinders correspondingly and are in threaded connection with the threaded cylinders. According to the carrier roller, the bottom plate, the T-shaped blocks, the bolt column and the middle carrier roller assembly are arranged, so that the distance between a first end plate and a second end plate isincreased, the axial length of a middle carrier roller is adjusted, and the supporting width of the middle carrier roller to a conveying belt is increased.

Description

technical field [0001] The invention belongs to the technical field of supporting rollers, in particular to a supporting roller with adjustable width. Background technique [0002] The idler roller is an important part of the belt conveyor. It has many types and large quantities, and can support the weight of the conveyor belt and materials. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% of the resistance. Therefore The quality of idlers is particularly important. There are two types of steel and plastic. The operation of the idler must be flexible and reliable. Reducing the friction between the conveyor belt and the idler plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the idler is in The belt conveyor is a small part with an uncomplicated structure, but it is not easy to manufacture high-quality idlers. [0003] Most of the existing rollers can only adjust...

Problems solved by technology

[0005] The object of the present invention is to provide a width-adjustable idler roller. By setting the low plate, T-shaped block, bolt column and intermediate idler roller assembly, the distance between the first end plate and the second end plate is increased, and the distance between the first end plate and the second end plate is adjusted. The axial length of the intermediate idler increases the support width of the intermediate idler to the conveyor belt, which solves the problem that the existing idler cannot adjust the support width
