Overview easy to convergence between the roller conveyor filter, available multiple drum line or plane and other transportation equipment logistics transportation system consisting of complex, multifaceted process needs to complete. Accumulating roller can be stacked to achieve delivery of materials. Roller conveyor simple structure, high reliability, ease of use and maintenance. Roller conveyor is suitable for conveying the bottom is flat items, mainly by the drive roller, rack, stand, drive unit and other components. With throughput, speed, running light, enables multi-species co-linear shunt transport characteristics. Constitute structural forms: from the driver divided into formal power, no power, electric rollers, etc., according to the layout of the form is divided into horizontal conveyor, inclined conveyor and turning delivery. And multi-layer transport. Rack Material: carbon steel, stainless steel, aluminum. Auxiliary accessories: file edge and roll edge protector. Principle Power mode: gear motor drive, electric drum-driven form. Transmission: single wheel, dual wheel, O-belts, flat friction belts, timing belts, etc., bobbin drive. Speed ??mode: frequency control, CVT, etc.
