Description

Technical Field

[0001] The utility model belongs to the field of hot stamping, and particularly relates to an intermittent hot stamping device. Background Art

[0002] Hot stamping technology, also known as "hot stamping", is a printing decoration process. It refers to the use of metal printing plates to emboss golden text or patterns on printed products. With the rapid development of hot stamping foil and packaging industries, the application of hot stamping technology has become more and more extensive.

[0003] In production, hot stamping processing technology is often coordinated with other printing processes to produce products with more exquisite patterns; however, traditional hot stamping technology can only be used for full rotary printing, so the hot stamping film and the printing material need to be the same length, but in fact the part of the entire printing material that needs hot stamping may only account for a small part of the printing material, which will cause a large amount of waste of hot stamping film and increase printing costs. Utility Model Content
