What is the conveying roller?
The conveying roller is one of the important components of the roller conveyor. The roller can form a complete set of conveying system with other conveyor equipment. The conveying roller has simple structure, high reliability and simple maintenance.
There are four types of conveyor roller: unpowered roller, power conveying roller , electric roller and rubber coating roller.
What are the classifications of conveying rollers?
According to the demand for product transportation, the rollers are divided into four types of conveyor roller: unpower roller, power conveying roller, electric roller and rubber coating roller. The following details the drum types:
Unpowered roller:
The unpowered roller is the most widely used type. It is simple in structure and installed in a horizontal or inclined manner. It mainly relies on product gravity or manual thrust to complete the transportation of goods.
The roller can be installed at the rear end of the high-speed cargo transportation to realize the function of guiding the loading and unloading of objects.
characteristic:
① The main structure of the universal unpowered transmission wheel is the head and tail plastic bearing end cover design, which is dust-proof and water-proof to a certain extent, and the transmission process is relatively stable, with little noise.
② The heavy-duty unpowered transmission wheel adopts the design of steel stamped bearing end cap. This kind of roller is durable and has superior load capacity. However, the heavy unpowered pulley can not be used as the idler of belt conveyor, because it is easy to cause problems such as rolling jam.
Power conveyor drum:
The power conveyor roller is a driven device with its own transmission structure, which mainly relies on the electric roller or internal motor to provide a certain driving force for movement.
The power roller is mainly divided into four transmission modes:
O-groove transmission: the transmission is carried out with round belt, and the transportation is realized by friction. O The grooves adjacent to the roller shall be arranged in a straight line to avoid excessive wear of the round belt. This is more suitable for conveying materials with light load
Chain wheel type drive: the chain wheel type drive roller is mainly used for transmission with gears and chains. Because of its high stability of transmission capacity, it is more practical to transport materials with high load.
Synchronous pulley type roller: it is used together with synchronous belt and synchronous wheel to ensure accurate positioning without slip
Multi wedge pulley type drive: The multi wedge pulley and the multi wedge belt are used together. Compared with the sprocket type power transmission roller, the former can further save installation space. Moreover, the multi wedge belt type power transmission roller has certain noise reduction and anti-skid capabilities, and is widely used in medium and high load scenarios.
Electric drum:
The electric roller is a new type of driving device which places the motor and reducer inside the roller. Compared with other traditional external motor drive equipment, the electric roller saves more space, and its installation and layout steps are more convenient and fast. It is mainly used in fixed and mobile conveyors to replace the traditional motor, and the reducer drives the separate drive device outside of the drum.
In the process of design, it is necessary to select the appropriate drum transmission mode, speed code, drag quantity and other requirements in advance according to the object load, linear speed, layout spacing and other restrictions.
The electric roller and the power conveying roller can also be used together according to the transmission type, mainly through the function adjustment of the drive card. Of course, the electric roller can also be directly used as the driving roller in the belt conveyor line or to achieve independent transition in the setting section.
rubber coated roller:
The rubber coated roller is an important part and component of the belt conveyor transportation system. The rubber coating of the roller can effectively improve the operation of the transportation system, protect the metal roller from wear, and prevent the slippage of the transportation belt. It is the synchronous operation of the roller and the belt, so as to ensure the efficient and large volume operation of the belt. The rubber coating of the roller can also effectively prevent the sliding friction between the roller and the belt, and reduce the material adhesion on the surface of the roller, Thus, the belt deviation and wear are reduced.
Application of conveyor roller
It is suitable for machinery, metallurgy, mining, port and dock, chemical medicine, cement and building materials, steel, coal mine and other fields. It is the driving device of various mobile belt conveyors, and can also be used for some fixed belt conveyors.
