Description

Paper lifting roller detection device Technical Field The utility model relates to the technical field of cigarette machinery, in particular to a paper lifting roller detection device. Background In the existing cigarette machine set, a double-color printing system performs double-color printing operation on cigarette paper through a first printing unit and a second printing unit. The first ink supply device supplies ink to the first steel seal roller and the second steel seal roller at the same time, and the single-color steel seal ink supply device supplies ink to the second steel seal roller. In the printing process, the coil paper is supported by a paper lifting roller and is contacted with a steel seal roller to finish printing. In the prior art, the execution of the lifting action of the lifting roller is finished by manual control of an operator, and under the conditions of equipment start and stop, paper breaking and restarting, equipment failure and the like, the problems of missed lifting of the lifting roller, insufficient lifting stroke and the like easily occur, so that the quality defects of steel marks such as no steel marks, incomplete steel marks and the like are caused. Taking 2024 production data of applicant as an example, the quality traceability event caused by the above problems reaches more than 20, which not only seriously affects the product quality, but also causes serious auxiliary material waste. Disclosure of utility model Aiming at the defects or the defects in the prior art, the utility model provides a paper lifting roller detection device which is used for solving the problem of steel seal quality defects caused by the problems of missing lifting of the paper lifting roller, insufficient lifting stroke and the like.
