Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the following description, for purposes of clarity, not all features of an actual implementation are described, well-known functions or constructions are not described in detail since they would obscure the invention with unnecessary detail, it being understood that in the development of any actual embodiment, numerous implementation details must be set forth in order to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, changing from one implementation to another, and it being recognized that such development efforts may be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art.

Referring to fig. 1, an apparatus for changing an offset printing unit into an embossing printing unit includes an ink path system; the ink path system is in contact with the plate cylinder 1; the plate cylinder 1 is in contact with the rubber cylinder 2; the lower part of the rubber roller 2 is provided with an impression roller 3, and one side of the rubber roller 2 is provided with a gap 4; the inner side of the gap is provided with a cavity 4.1; a tensioning block 5 is arranged in the cavity; the tensioning block 5 is elastically connected in the cavity through a spring 6; the surface of the tensioning block is provided with a first screw hole 5.1.
