Description

Technical Field

[0001] The utility model belongs to the technical field of hot rolling inkjet printers, and in particular relates to a device for offline debugging of a spray gun. Background Art

[0002] The numbering machine plays a vital role in the rolling mill production process, primarily responsible for spraying information onto each coil. The proper operation of the numbering machine is essential for the smooth operation of the production line. However, if the numbering machine malfunctions, the production process must resort to manually writing the coil numbers. This handwritten method presents numerous problems, such as the irregularities of the handwritten numbers. Due to individual handwriting variations, the coil numbers are difficult to read and prone to errors. Furthermore, the coils reach extremely high temperatures during production, and handwriting the coil numbers can easily harm workers and even cause safety accidents. Especially with the increasing demands on product image today, handwritten coil numbers are often not permitted because they fail to meet high quality standards.

[0003] The current high-speed production pace at production sites accelerates wear on the printer needles and seals. When a spray gun needs to be taken offline for repair, it must undergo repeated commissioning before being put back into service to ensure it is free of defects and maintain print quality. However, under existing conditions, commissioning must be performed on the printer head, significantly impacting printer uptime. This time-consuming commissioning process results in many coils not being numbered in time or experiencing poor print quality, forcing manual numbering. This not only easily leads to incorrect coil numbers but also creates significant inconvenience during transportation, management, and delivery. It can easily cause confusion between fonts and potentially lead to burns or heatstroke during high summer temperatures. To address this issue, on-site staff developed a simple offline gun commissioning mechanism. This mechanism allows for the repair of offline guns while maintaining normal printer operation. This significantly reduces online repair time and improves printing efficiency. Utility Model Content
