Description

Rotatory hoist of hardware and tools application suspension chain Technical Field The invention belongs to the technical field of hanging conveying equipment, and particularly relates to a rotary lifting appliance for a hardware tool coating hanging chain. Background In the spraying process of hardware tool production, the suspension chain conveyor plays a role in continuously conveying the hardware workpieces, the hardware workpieces to be sprayed are suspended on the overhead rail to continuously run at a constant speed, the working procedures of pretreatment, spraying, drying, solidification and the like of the hardware workpieces are connected in series, the hardware workpieces are exposed at 360 degrees due to the suspension conveying mode, and the dead-angle-free spraying coating cover can be realized by matching with the rotary lifting appliance. Hanging chain conveyor spreaders are key actuators in hanging conveyor systems, typically connected to a traction chain, for carrying and securing hardware work pieces by a specific hanging structure (e.g., rigid boom, articulating frame, or special clamps). The special fixture or hanger for the design of different hardware workpieces can be accurately matched with the positioning requirements of procedures such as spraying, assembling, detecting and the like. At present, common tool hanging tools are hung in a mode that a single hook is matched with a corresponding positioning hole on a hardware workpiece. However, due to the dimensional tolerance difference of the apertures of the positioning holes on different hardware workpieces, when the apertures are larger, larger fit clearance can be formed between the hooks and the hole walls. In the running process of the conveying chain, the gap is easy to cause the hardware workpiece to swing obviously on the hanger. Especially when passing through the spraying station, the instability of the position of the hardware workpiece can cause the fluctuation of the distance between the spray gun and the surface of the hardware workpiece, thereby affecting the uniformity of the thickness of the coating and the overall spraying quality.
