Description

Technical Field

[0001] The present invention belongs to the technical field of can body printing ink curing, and specifically relates to an ink curing device for can body printing. Background Art

[0002] Cans can be used to store various things, such as food, beverages, chemicals, etc. In terms of materials, there are metal cans, such as aluminum cans and steel cans; the shapes and sizes of cans are also diverse, including round and square. Can body printing requires the use of special inks and printing equipment to ensure that patterns and words are clear and durable. After the can body is printed, the ink on its outer wall needs to be cured. However, the natural curing of ink takes a long time. Therefore, an ink curing device for can body printing is usually used. Therefore, there is a need for an ink curing device for can body printing.

[0003] The existing ink curing devices for can body printing have certain drawbacks when in use. When the existing ink curing devices for can body printing are in use, they usually use hot air curing technology to cure the can body ink. However, hot air curing requires a large amount of heat energy to heat the air and maintain the required high-temperature environment. The long-term high-temperature environment will reduce the service life of the curing device and the conveying structure. Moreover, waste gas will be generated during ink curing, and the high-temperature environment will increase the volatilization rate of harmful substances in the waste gas, resulting in an increase in waste gas concentration. This not only exacerbates environmental pollution but also increases the risk of operators being exposed to harmful substances, unable to meet people's needs. Summary of the Invention
