Technical Field

[0001] The utility model belongs to the technical field of conveyor lines, and particularly relates to a power transmission mechanism for suspension conveying. Background Art

[0002] Suspension conveyor lines are automated conveying equipment widely used in multiple industries such as automobile manufacturing, home appliance production, food processing, and logistics distribution. Suspension conveyor lines can convey materials of various shapes, sizes, and weights, such as parts, finished products, and packing boxes. Among them, there is a suspension conveyor line driven by belt friction, which has a compact structure, high reliability, and good soft start performance, and is widely used in various industries. In belt drive, it is necessary to ensure that the belt has appropriate tension to ensure effective transmission. However, in long-distance transmission, the belt requires greater tension to maintain tension, which easily leads to additional wear, and the increase in length will cause a decrease in transmission efficiency and even slippage.

[0003] Therefore, the above problems need to be solved urgently. Content of the Utility Model

[0004] Purpose of the utility model: In order to overcome the above deficiencies, the utility model provides a power transmission mechanism for suspension conveying, which avoids the easy slippage of the belt in long-distance transmission, improves the transmission efficiency, and reduces the wear of equipment such as belt guide wheels.

[0005] Technical solution: To achieve the above object, the utility model provides a power transmission mechanism for suspension conveying, which includes a first conveying track and a second conveying track.
