Design of conveyor roller line

2019-12-04

The power roller line is one of the main conveying accessories in the conveying equipment. It is a cylinder shaped component that automatically drives the Conveyor Belt or changes its conveying direction. Most of them are used for transportation of goods with flat bottom, mainly composed of driving drum, frame, bracket, driving part, etc. The utility model has the advantages of large conveying capacity, fast speed and light operation, and can realize multi varieties of collinear shunt conveying. The Power Roller Conveyor line has the advantages of simple structure, high reliability, convenient operation and maintenance, and can bear large impact load. It is widely used in all walks of life in cost packaging and transportation, as well as in turnover transportation.



Working principle



Power roller line conveyor is usually used in horizontal or upward slightly inclined transmission line. The driving device transmits the power to the roller, makes it rotate, and transports the goods through the friction between the roller surface and the surface of the transported goods.



The power Roller Conveyor is mainly composed of two end rollers and the closed conveyor belt on the tight sleeve. The drum that drives the conveyor belt to rotate is called driving drum (driving drum); the other drum that only changes the moving direction of the conveyor belt is called changing drum.



The driving roller is driven by the motor through the reducer, and the conveyor belt is driven by the friction between the driving roller and the conveyor belt. Generally, the driving roller is installed at the discharge end to increase the traction and facilitate the dragging. The material is fed from the feeding end and falls on the rotating conveyor belt. The friction of the conveyor belt drives the unloading end of the conveyor bag to unload. The principle of the single chain roller conveyor is that the roller is driven by a ring chain, and the chain runs in a special guide rail, which has the characteristics of convenient installation and low noise. Single chain wheel roller is driven by large cycle, double chain wheel roller is driven by small cycle, and other driving methods are used in light transportation occasions. It is applicable to the transportation of all kinds of boxes, bags, pallets and other items. Bulk materials, small items or irregular items need to be placed on pallets or transported in turnover boxes.



Power drum line parameters



The transmission mode includes single (double) sprocket, single (o) belt, single (double) synchronous pulley and belt drive. The matching sprocket is p = 12.7mm; Z = 14; P = 15.875mm; Z = 14. Drum diameter is 50.8, 60, 75, 89 (mm); turning radius of turning roller conveyor is 900mm, 1200mm;



1. Roller material: galvanized, aluminized, stainless steel, PVC, etc.



2. Roller type: Double sprocket cone roller; o-groove roller, ordinary cone roller.



3. Drum length: generally 500 ~ 1200mm; it can be customized according to the user's requirements.



4. Wire support: stainless steel, aluminum profile, carbon steel spray molding, etc.



5. Conveying speed: generally 10 ~ 30m / min; variable frequency speed regulation can be adopted for continuous operation according to the user's requirements.



6. Non standard power roller line is customized according to specific requirements.



Power roller conveyor equipment



According to the driving mode, there are separate driving and group driving. Each roller of the former is equipped with a separate driving device for easy disassembly. The latter is a group of rollers driven by a driving device to reduce the cost of equipment. The driving modes of group drive include gear drive, chain drive and belt drive. The power roller conveyor is generally driven by AC motor, and it can also be driven by two speed motor and hydraulic motor as required.



The power roller conveyor can also be divided into linear power roller conveyor, turning power roller conveyor, power roller conveyor, free power roller conveyor, heavy power roller conveyor and rubber covered power roller conveyor;



Standard turning inner radius of turning roll line: 300, 600, 900, 1200mm, etc. or customized;



Diameter of straight section drum: 38, 50, 60, 76, 89mm or customized;



Layout: horizontal conveying, inclined conveying and turning conveying;



Structure form: from the driving form, it can be divided into power, electric roller, etc;



Frame material: carbon steel spray, stainless steel, aluminum profile;



Power mode: deceleration motor drive, electric roller drive and other forms;



Transmission mode: single chain wheel, double chain wheel, o-belt, plane friction transmission belt, synchronous belt, etc;



Speed regulation mode of power roller conveyor: variable frequency speed regulation, stepless speed regulation, etc;



Drum line classification



According to the power form, it can be divided into non power roller and power roller



Unpowered Roller: a cylindrical component that drives the conveyor belt manually or changes its running direction. It is one of the rollers and the main accessory of the conveying equipment.



The power roller is divided into single chain wheel roller, double row sprocket roller, pressing groove power roller, synchronous belt power roller, multi wedge belt power roller, electric roller and accumulation roller.



The power roller line, together with the jacking transplanter, can realize 90 degree, 180 degree and 270 degree turning movement. The drum diameter is 60x3.0, and the load is about 500kg. 90 degree power roller, used for corner conveying, high efficiency and low cost.
