Description

Technical Field

[0001] The utility model relates to the technical field of printing processing, in particular to a movable corona structure for digital printing. Background Art

[0002] In the winding structure of digital printing, materials come out from the hot stamping process of the printing section, and successively pass through a visual inspection structure, a flexographic plate holder, a curing lamp, a traction structure, and finally enter the winding process.

[0003] During the printing and winding process, corona treatment is an important link, which is mainly realized through a corona machine. The corona machine generates ozone and low-temperature plasma through high-voltage discharge. These active substances can improve the surface characteristics of materials, such as increasing surface tension, improving wettability, enhancing adhesion, etc. During printing and winding, corona treatment mainly acts on the surface of materials before winding, such as films, papers, etc. Through corona treatment, the surfaces of these materials can be made smoother and flatter, and surface stains, oils and other impurities can be removed, thereby improving the printing quality and winding effect. Specifically, corona treatment can improve the adhesion of ink on the material surface, making the printed pattern clearer and more vivid; at the same time, it can also enhance the adhesion between materials, preventing problems such as delamination and shedding during the winding process. In addition, corona treatment can also reduce the occurrence of static electricity, avoiding printing failures and poor winding caused by static electricity.

[0004] When an additional set of corona machines is needed before winding in the existing structure, it cannot be quickly used. However, modifying the existing structure takes a long time and occupies a large space. Now, a corona machine installation structure is designed to solve the problems of inconvenient installation and complex operation when a corona machine is needed, and when the corona machine is not needed, it can be moved away without occupying space and without disassembly. Therefore, we provide a movable corona structure for digital printing. Content of the Utility Model

[0020] Corona machines usually have relatively large sizes and weights, which makes it difficult to move and install them in printing workshops or production lines. Especially in production environments with limited space or compact layouts, the installation of corona machines may require additional equipment or manpower to assist in completion. Corona machines require a stable power supply and correct electrical connections to ensure their normal operation. However, during the actual installation process, problems such as inappropriate power socket positions, insufficient power cord lengths or complex electrical connections may be encountered, all of which require sufficient planning and preparation before installation. In a printing production line, corona machines usually need to be used in conjunction with other equipment (such as printing presses, coating machines, etc.). This may require certain adjustments or modifications to the production line. The reasons for the inconvenient installation of corona machines during printing may involve multiple aspects such as equipment size and weight, power supply and electrical connections, compatibility with other equipment, installation environment and requirements, and the complexity of operation and maintenance.
