6. Conveying Length: 280 Meters Due to the long and thin characteristics of the user's workpiece, in order to meet the requirements for online fully automatic coating of such large workpieces, we designed an accumulation conveying system. Its characteristic is to avoid the rotation of long workpieces during the conveyance process. The problem of excessive floor space is solved. At the same time, each process end of the entire line can choose to stop accumulation or movement according to the needs of the automatic control method, thus saving the floor space of the entire equipment and reducing the energy consumption of the oven.
