Description

Technical Field

[0001] The utility model relates to a number spraying device, in particular to a device capable of spraying and marking the surface of packaged steel strips, belonging to the technical field of steel strip marking equipment. Background Art

[0002] Strip steel is a narrow and long steel plate produced by steel enterprises to meet the needs of various industrial processing. After being transported to the processing plant, the strip steel is processed and processed into the required products. The strip steel is coiled from the steel plate. After the steel plate is coiled and packaged, in order to facilitate the subsequent processing manufacturers to understand the parameters of the strip steel, it is necessary to spray the corresponding parameters on the surface of the strip steel, that is, to label the surface of the strip steel. At present, there are methods for strip steel spraying, including mechanical arms and manual spraying. Among them, the cost of mechanical arm spraying is high, and the subsequent maintenance cost is also high, and there is a failure rate, which will affect the progress of spraying. In the case of manual spraying, the spraying operation is completed by spraying number plates. The position of the existing spraying number plates is fixed, so it is easy to spray the number on the strapping tape during spraying. When the strapping tape is displaced or falls off, the spraying number will also be offset, resulting in the inability to identify the parameters of the strip steel later. Therefore, a spraying device is needed, which is required to assist the staff to spray the strip steel efficiently. Utility Model Content
