What is Rulo? Location in conveyor structure
Rulers and their structure
With today’s diverse conveyor lines, conveyor belt accessories are indispensable in the structure and operation of the conveyor. The roller has a rolling cylindrical structure and connects the conveyor structure: motor – belt for reciprocating movement. Rollers release conveyor belts, used to provide power transmission for lifting and moving equipment, many applications in the structure of equipment.
On the outside, the roller is usually very simple, but the internal structure has many textures and requires technical calculations with high accuracy. Roller structure: roller shell, roller shaft, flange, roller spokes, processing accessories to create surface roughness: rubber, PVC… The structure is quite similar to rollers, making many people still confused about 2 lines of tape accessories. download this. But in 1 conveyor system can have many rollers but only 2 or maximum 3 or 4 rollers for long conveyor system. Roller material can be steel, stainless steel or cast iron.
The role of the roller in the conveyor
The roller plays an important role in the operating principle of the conveyor belt, connecting and transmitting the force from the motor to the conveyor by friction with the underside of the belt to move the weight forward for the conveyor system. The roller helps to align and stretch the conveyor belt to help the belt move easily and safely for goods and cargo. Conveyor rollers are usually mounted at 2 ends of the conveyor belt with active and passive increases or with 1 or 2 counterweight rollers in between. 2 roller heads are directly attached to the conveyor frame, conveyor chain and are in direct contact with the lower surface of the belt.
Classification of application rollers in conveyors
Technical characteristics of conveyor rollers
Conveyor rollers have the same structure and operation as the roller system, but play a different role in helping the system move.
• The roller needs to be designed concentrically, without causing centrifugal force, surface sag affects the conveying capacity of the belt.• The roller is treated with high roughness surface to make contact and create force to move the tape. effective. Surface corrosion resistance, high mechanical strength. • Stable roller structure, long-term operation, less technical error correction and replacement and repair.
Types of rollers used in conveyor design
Important applications in industrial conveyor belts of all kinds. Therefore, the material and structure will have many differences to be improved to meet the requirements of production and system operation.
• Currently, rollers can be classified into types according to material: rubber coated roller, spoke roller, tubular roller, PVC coated roller.• Classification according to operating principle: active roller – active drum, passive roller – passive tang, counterweight roller – increase only the ribbon.
Order quality rollers for safety conveyors
Safety roller design standards
The roller transmits the force from the motor to the conveyor belt, ensuring a stable and long-term reciprocating system. The roller design needs to ensure accurate calculation, alignment of the shaft and the concentric roller shell, without causing centrifugal shaking of the conveyor belt.
The roller needs to have high rigidity, impact resistance, and anti-distortion that affects the grip of the conveyor belt on the surface of the roller. Corrosion-resistant roller material, stable operating ambient temperature conditions for a long time.
When machining rollers, it is necessary to pay attention to the following parameters: pipe diameter, shaft diameter, pipe thickness, surface treatment.
Learn what is a rulo and effective ordering specification
Industrial conveyor design is a combination of many accessories, with conveying characteristics and circular motion of the cylinders. The roller is an important conveyor accessory that creates the operability of the entire conveyor system. Understanding what is the rule? The design and movement of the roller in the conveyor structure will help users understand and place orders efficiently. Below is the necessary information for businesses and customers interested in conveyor rollers of all kinds.
Learn about the concept of rulo
The roller is a moving accessory of the conveyor belt, often mistaken for a roller by users. Because of its round cylinder design and its characteristics a bit like a roller. But in fact, the roller takes on a completely different task in the conveyor structure and the structure is also different.
Rulo also has a name Other names such as: tank, spool or zulo. In a conveyor system, there are only at least 2 rollers at the beginning and end of the conveyor, or more when there are 2 or 3 more rollers in the middle for a long conveyor system. This is the difference with conveyor systems with many single rollers in the structure.
To classify rollers, based on their structure, there will be 2 types: pipe rollers and spokes rollers. Based on the principle of operation, there will be active rollers, passive rollers and counterweight rollers. Rulo is used in many conveyor belt lines: PVC conveyor belt, PU conveyor belt, stainless steel chain, bucket conveyor … more diverse applications in equipment such as thread tractors, piers, textile field…

Structure of the roller
Based on the characteristics of the roller structure, it is classified into 2 main types. The structure of these two lines of rollers has many differences and different advantages and disadvantages to note:
The tube roller type has the most applications and is used in many systems. Specific pipe roller structure:
Tubular rollers have their own advantages and disadvantages that make them unique and industrially available.
Roller advantages: solid roller structure and structure, stable operation, many designs and models to choose from, flexible specifications. With the characteristic of bearing and anti-corrosion material in effective environmental conditions.
Disadvantages: the roller surface often has poor friction, needs to be surface processed to improve, weak shaft and flange connections need additional reinforcement to increase force, difficult machining.
The type of roller is not as commonly used as the pipe roller, but the spoke roller is used a lot in conveyor structures, transporting goods. Specific spokes roller structure:
Roller shaft – a large bearing part, so depending on the required bearing characteristics, choose a tubular or solid steel as a cylinder. Roller cam – is a solid round or tubular steel rod, welded in a circle on the flange. with arbitrary distance of spokes.Flange – round metal piece, with thickness and glass thickness according to user requirements and operating conveyor system characteristics.
Advantages of spokes rollers: high friction, easy grip when in contact with conveyor belts. The cost of spokes rollers is much cheaper than that of pipe rollers and is easy to process.
Cons of the spokes roller: weak link structure, moderate load bearing, need to calculate detailed bearing and careful welds to avoid damage to the rubber band, design with few parameters and characteristics, unattractive appearance. eye-catching is a weakness.
Operating principle of roller in conveyor
The roller operates on a fairly simple principle, with a design of 2 roller models at the beginning and the end of the conveyor. Active roller with long shaft design to connect with motor or pulley. The motor transmits the motion, the sprocket moves and the roller rotates. Thanks to the design of bearings, the roller makes the active rotation easy. The conveyor belt is in contact with the active roller by friction. When the active roller rotates, the conveyor belt moves forward.
The passive roller is designed with a smaller diameter than the active roller, which acts as an auxiliary for conveyor movement. Taking on the role of tensioning the conveyor belt in motion, operating in a circular cycle, stable without overlapping the belt, reducing operation ability. The conveyor belt will move in a circle around the active and passive roller shafts thanks to the tension, friction and movement of the roller.
The larger the active roller design, the higher the friction, the stronger the pulling force and the faster the speed of the belt movement, improving the conveying efficiency.
Application of role model in production
With the available technology characteristics, different types of rollers are applied in each field to improve the efficiency of operation and use. Rulo is widely used in the design of conveyor belts transporting public – agricultural goods, machinery design.
The spokes roller is an indispensable part for the efficient operation of the bucket conveyor. The pipe roller is widely used in the fields of textiles, printing, thread pulling, crane hoists.
