Adsorption type cutting device for paper of multiple specifications

Abstract

The invention discloses an adsorption type cutting device for paper of multiple specifications, and belongs to the field of papermaking devices. The adsorption type cutting device comprises a paper pressing mechanism and a paper cutting mechanism which are arranged in the paper feed direction. The paper pressing mechanism comprises a vacuum pump and an adsorption plate internally provided with a cavity. A plurality of adsorption holes communicated with the cavity are formed in the upper plate face of the adsorption plate. Through holes communicated with the cavity are formed in the side face of the adsorption plate and are connected with the vacuum pipe through pipelines. The paper cutting mechanism comprises a paper cutting roller and an anvil roller located below the paper cutting roller. The paper cutting roller and the anvil roller each comprise a roller body and a plurality of sleeves axially arranged outside the roller body in a sleeving mode. Annular grooves which are formed in the axial direction at intervals are formed in the outer circle face of each roller body, wherein sections of the annular grooves are each in an arc shape. Positioning structures are arranged in inner circle faces of the sleeves. Cutters are fixed to the sleeves of the paper cutting roller. Paper of multiple specifications can be cut at the same time, different cutting requirements are met, adjustment is easy, convenient and reliable, cutting specifications are diversified, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to an adsorption type multi-standard paper cutting device. Background technique [0002] With the development of social economy and the advancement of science and technology, the social demand for paper cutters continues to increase. Paper cutters are widely used in the printing and packaging industries. They are mainly used to cut paper of various specifications and thicknesses. To meet various needs of use. It is troublesome to adjust the position of the cutter of the currently used paper cutter, and the cutting specifications to be satisfied are single, and some will use anvil rollers for the convenience of cutting. The cutter cuts, but the position of the cutting groove cannot be adjusted. It is necessary to replace the anvil roller to meet the needs of different cutting positions, and the efficiency is low.
