Description

Technical Field

[0001] The utility model relates to a belt conveyor device, in particular to a transition conveyor line device for small-sized high-center-of-gravity workpieces, and belongs to the technical field of belt conveyor line docking. Background Art

[0002] In the scenario of long-distance and stable transportation of workpieces, the docking combination of conveyor lines is very common. Due to the gap between the rollers at the transition point of the two belt conveyor lines, it may cause the small-sized and high-center-of-gravity workpieces to be unable to pass or fall when passing through the conveyor line docking point (see Figure 1 ). If the rolling clearance is reduced by simply reducing the diameter of the active roller and the driven roller, the speed of conveying the workpiece will be affected at the rated speed of the motor and the installation difficulty will increase. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a transition conveyor line device for small-sized high-center-of-gravity workpieces, by arranging a small-diameter docking roller at the docking point of two sections of belt conveyor lines, the diameters of the two docking rollers match the size of the roller gap at the docking transition point of the two sections of belt conveyor lines, ensuring that small-sized high-center-of-gravity workpieces can pass through the docking transition point smoothly.

[0009] During operation, manual unloading is performed at the position of the manual range limiting device of the first conveyor belt. The small-sized high-center-of-gravity workpiece moves along the conveyor line of the first conveyor belt to the transition centering guide device for centering before docking transition, and then moves to the second conveyor belt through the conveyor line docking point to complete a smooth transition.
