[0002] Metal printing refers to the technology of printing patterns or text on metal surfaces. This technology is widely used in many industries, including packaging, home appliances, automobiles, construction, etc. Metal printing can not only beautify products, but also provide necessary information identification. Metal printing includes metal sheet printing, which refers to the process of printing patterns or text on metal plates or sheets.

[0003] Existing metal printing usually involves manually placing the metal on a conveying device, which then transports the metal to the bottom of the printing device for printing. Currently, manual placement of the metal is difficult to ensure that the metal is placed in the center every time, which can easily cause the metal position to shift, resulting in a shift in the printed pattern, thereby affecting the quality and efficiency of printing and making it inconvenient to use.

[0004] Therefore, it is necessary to design a metal printing device with a feeding centering function that can center the metal sheet during feeding, prevent the metal sheet from shifting, improve the quality and efficiency of printing, and at the same time, use a baffle to block the printing only on the position where printing is required, preventing the paint from being printed in other places, and is easy to use.
