Description

Technical Field

[0001] The utility model relates to the technical field of vacuum paper feeders, in particular to a novel vacuum paper feeder. Background Art

[0002] At present, in the papermaking process, most of the paper strips are led into the papermaking equipment through a vacuum paper feeder. The existing vacuum paper feeder is composed of a frame, a driving roller, a driven roller, a driving mechanism, an annular mesh belt and a vacuum generator. After the paper strip is placed on the annular mesh belt, a vacuum is generated under the paper strip through the vacuum generator, and the paper strip is adsorbed on the annular mesh belt through the air pressure difference. Then, the paper strip is transported to the papermaking equipment through the rotating annular mesh belt. For example, a vacuum paper feeder disclosed in Chinese patent announcement number CN207632186U, but because dust in the air will be directly adsorbed on the air inlet of the vacuum generator, the air inlet of the vacuum generator is often blocked by dust, which reduces the attraction of the vacuum paper feeder to the paper strip and causes the vacuum paper feeder to fail to transport the paper strip normally. At the same time, because the paper strip on the annular mesh belt is not limited when the paper strip is transported, the position of the paper strip is often offset, which affects the subsequent processing of the paper strip.
