The roller turning conveyor is mainly composed of a driving roller, a frame, a support, a driving part and the like, and is suitable for conveying articles with a flat bottom. It is divided into powered, unpowered, and electric drums from the driving form, and is divided into horizontal conveying, inclined conveying and turning conveying according to the layout form.
The inner width of the roller conveyor is specified by the customer and can be produced according to customer requirements. The standard turning inner radius of the turning line is 300, 600, 900, 1200mm, etc., and other special specifications can also be adopted according to customer requirements. Straight rollers have roller diameters of 38, 50, 60, 76, 89mm, etc. The taper of the turning drum will be designed according to the weight, shape and linear speed of the conveyed object.
Frame material: carbon steel spray, stainless steel, aluminum profile.
Power mode: drive by reduction motor, drive by electric drum, etc.
Transmission mode: single sprocket, double sprocket, O-belt, flat friction transmission belt, timing belt, etc.
Speed regulation mode: variable frequency speed regulation, stepless speed change, etc.
The roller turning conveyors are easy to connect and filter, and multiple roller lines and other conveying equipment or special machines can be used to form a complex logistics conveying system and a shunting and combining system to complete various process needs. The structure is simple, high reliability, easy to use and maintain. The power roller line needs to consider the tensile strength of the chain, and the longest single line length generally does not exceed 10 meters.
In gravity roller conveyor applications, the use of open or steel shielding covers can avoid increasing the friction of the bearings. Although the application temperature of the bearing can be as high as 170 ° C, the temperature of the steel shielded bearing cannot exceed 100 ° C, because the shielding cover will be deformed. In higher temperature applications, the interval between conveyor belt loads should be increased and moved quickly to reduce the absorption of heat from the drum.
The load capacity of the roller is determined by the bearing load capacity and the width of the roller. The basic bearing load capacity is determined by empirical formulas and experimental tests. Rated with a narrow width conveyor. If the width increases, the load capacity of the roller will decrease due to the deformation of the shaft.
There are three types of assembly methods: direct pressing type, curling type and forming type. The roller assembly on the skeleton track can be higher or lower than the skeleton. If the roller is lower than the skeleton track, the skeleton track can be used as a guide rail without installing a safety fence. If a wider load is used, it cannot be used because the load will interfere with the skeleton.
Relatively, the roller is higher than the frame, and a safety fence is installed, which is more flexible in application. The most common skeleton types are channel steel, L-shaped steel or flat plate. Divided by the forming method, it can be divided into bending forming and structural steel. The structural steel has a heavier weight and better strength, and is used for heavy loads. Usually, the same steel is used on both sides of the conveyor and welded by the supporting beam Or bolted. For some specific applications, the types of the two sides of the skeleton are not the same.
