A uniform inkjet printer for stainless steel is an industrial-grade printing device primarily used for precise inkjet printing on the surface of stainless steel materials. This device has a wide range of applications, including but not limited to printing patterns, text, or barcodes on stainless steel sheets, suitable for product identification and tracking.

[0003] However, the existing device does not have a component for plasma treatment of the surface of stainless steel before spraying, which cannot improve its surface properties, enhance ink adhesion, and replace the plasma treatment component if it is damaged. Utility Model Content

[0004] The purpose of this application is to provide a uniform inkjet printing device for stainless steel, in order to solve the problems that the aforementioned device does not have a component for plasma treatment of the surface of stainless steel before spraying, thus failing to improve its surface properties and enhance ink adhesion, and that the plasma treatment component cannot be replaced when damaged.

[0005] The technical solution adopted in this application is as follows: it includes an ink supply body, a plasma equipment mounting slot is fixedly installed on the upper surface of the ink supply body, a power supply and gas supply interface is fixedly installed on the upper surface of the plasma equipment mounting slot, an atmospheric plasma generator is fitted onto the upper surface of the plasma equipment mounting slot, multiple compressed gas cylinders are threaded onto the upper surface of the atmospheric plasma generator, multiple docking rings are fixedly installed on the upper surface of the plasma equipment mounting slot, and bolts are installed on the internal threads of the atmospheric plasma generator and the docking rings.

[0006] By adopting the above technical solution, a plasma equipment mounting slot is fixedly installed on the upper surface of the ink supply unit. A power supply and gas supply interface is fixedly installed on the upper surface of the plasma equipment mounting slot. An atmospheric plasma generator is fitted onto the upper surface of the plasma equipment mounting slot. Multiple compressed gas cylinders are threaded onto the upper surface of the atmospheric plasma generator. Multiple docking rings are fixedly installed on the upper surface of the plasma equipment mounting slot. Bolts are threaded onto the atmospheric plasma generator and the docking rings. The ink supply unit serves as the mounting base for the entire device, connecting the various components. The plasma equipment mounting slot provides a location for installing the plasma components. The power supply and gas supply interface internally includes a power supply and control interface connected to the internal circuitry of the ink supply unit, as well as a pipe interface for supplying generated gas to the outside, ensuring the plasma assembly can operate normally after installation. The atmospheric plasma generator, as the main component of the plasma assembly, generates plasma and utilizes the high-energy particles generated by the plasma to ionize the stainless steel surface. Physical or chemical modifications are performed to improve surface properties and enhance ink adhesion. Simultaneously, plasma removes oil, dust, oxide layers, and other impurities from stainless steel surfaces, providing a clean base for subsequent inkjet printing.

The inner ring of the docking ring aligns with the threaded holes in the atmospheric plasma generator, providing a connection for fixing the atmospheric plasma generator to the outer surface of the plasma equipment mounting slot. Screwing bolts into the docking ring and the atmospheric plasma generator secures the plasma assembly. Loosening the bolts from the docking ring and the atmospheric plasma generator allows damaged plasma components to be removed and replaced. By installing components in this device to plasma-ionize the surface of stainless steel before spraying, surface properties are improved, ink adhesion is enhanced, and damaged plasma-ionized components can be replaced.

[0015] In a preferred embodiment, a corrugated hose is fixedly installed on the lower surface of the docking valve through the ink supply unit, and a delivery pump is fixedly installed on the other end of the corrugated hose.

[0016] By adopting the above technical solution, a corrugated hose is fixedly installed through the ink supply unit on the lower surface of the docking valve.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0022] In this application, the atmospheric plasma generator serves as a key component of the plasma assembly. By generating plasma, it utilizes the high-energy particles produced by the plasma to physically or chemically modify the stainless steel surface, thereby improving its surface properties and enhancing ink adhesion.
