Description

Technical Field

[0001] The utility model belongs to the technical field of spray printing, and particularly relates to a steel pipe length marking device. Background Art

[0002] In steel pipe production, the finishing line is equipped with a spray marking device for marking the pipes. Traditional spray marking machines are placed alongside pipe alignment, length measurement, and weighing, collectively referred to as length measurement, weighing, and spray marking units. Generally, the pipes are first aligned. After alignment, a steel transfer machine moves the pipes to the length measurement station. After length measurement, the pipes are weighed, then moved to the weighing station. The steel transfer machine then moves the pipes to the spray marking station for marking. Afterwards, the steel transfer machine moves the pipes out of the spray marking station, and the pipes proceed to the next process. Pipe alignment, length measurement, weighing, and spray marking work all begin in parallel, so the production rhythm is determined by the longest process plus the operating time of the steel transfer machine. Of these processes, spray marking takes the longest time, especially for marking long lengths. The spray marking process is the one that impacts the production rhythm, especially for marking long lengths, as measured by the length measurement, weighing, and spray marking units.

[0003] In view of the above factors, a steel pipe length marking device is specially designed. Two or more marking machines are set on the crossbeam of the gantry of the marking station, and printing is carried out on the outer surface of the steel pipe at the same time, which improves production efficiency.
