Compact synchronous belt conveyor

The utility model provides a compact synchronous belt conveyor, relates to the technical field of conveying equipment, and solves the technical problems that the width of a conveyor is large and the use requirement cannot be met. The compact synchronous belt conveyor comprises a frame, and a driving synchronous wheel and a driven synchronous wheel are arranged at the two ends of the frame respectively. The driving synchronous wheel and the driven synchronous wheel are sleeved with a conveying belt. A power input unit, a reverser and a transmission assembly are further arranged in the frame, the power input unit is arranged in the length direction of the frame, and the reverser is connected to the power input unit to conduct power input reversing; the transmission assembly is connected between the reverser and the driving synchronizing wheel. The power input unit is arranged in the length direction of the frame, the width of the conveyor can be slightly larger than that of a servo motor or a speed reducer, the
