Oriented quantitative arc support roller

Abstract

An oriented quantitative arc support roller has the advantages of uniform abrasion of the support roller, and capabilities of reminding the replacing time, prolonging the service life, preventing a conveyor belt from sliding downwards and reducing the safety risk in operation. The oriented quantitative arc support roller is characterized in that the drum body is a round drum with two large-diameter end parts and a small-diameter middle part; the roller generatrix of the drum body is an arc line; an abrasion alarm slot and abrasion indication tables are respectively designed in the middle position and two sides of the drum body; a unidirectional moving mechanism is arranged at one or two sides of the drum body; the unidirectional moving mechanism comprises a counter-rotation prevention device and a ratchet wheel arranged on a shaft by a key slot; the returning stopping lock tail end of the counter-rotation prevention device is contacted with the ratchet wheel. The oriented quantitative arc support roller has the advantages of prolonging the service life of the support roller and a belt, preventing the left-right swing of the belt and the deviation of the belt, reducing the risk that the belt is torn and the support roller is abraded through, preventing the swing back and forth of the belt, improving the production stability, facilitating the maintenance, inspection and management, and preventing the safety accidents caused by the counter-rotation of the belt.

Description

technical field [0001] The invention relates to idler rollers used in places such as conveyors, in particular to a directional and quantitative arc-shaped idler roller which is safer, more reliable, wear-resistant, less likely to deviate from the conveyor belt, can rotate directionally, and wears an arc with quantitative markings. Background technique [0002] The use range of idlers is very wide and there are many varieties. Under normal circumstances, although the idlers account for about 35% of the cost of the entire conveyor, whether the structural design and processing of the idlers and the use of materials are reasonable and scientific will have a great impact on the life, safety, reliability, and energy consumption of the conveyor belt and idlers. have a direct impact. [0003] At present, idlers are divided into metal idlers and non-metal idlers according to their materials, and non-metal idlers are basically divided into rubber idlers, ceramic idlers, nylon idlers,...

Problems solved by technology

[0005] In addition, during the use of all the current idlers, the wear degree of the idler cannot be intuitively indicated. If the idler wears too much and is not replaced in time, the outer cylinder of the idler will wear through and damage the belt.

The outer cylinder of the roller wears too little and needs to be replaced, which is a waste, and it is inconvenient to manage the use of the roller

At present, when the various idlers are in use, there are too many belt transport materials or the friction force of the roller surface decreases. When the torque is greater than the belt roller, it will become a major safety hazard.
