Abstract

The invention discloses a paper machine rewinding slitting device and a dust removal system thereof. The paper machine rewinding slitting device comprises a top knife post, a top knife holder, top knife devices, a dead knife device, a guiding roller assembly and a dust removal device, the knife holder is arranged on the top knife post, the top knife holder is provided with a plurality of top knifedevices, the top knife devices are provided with top knives, knife mounting switches, knife change switches and air cylinders, and the outside of the top knives are provided with top knife dust removal covers; and the dead knife device is internally provided with an auxiliary top knife, the auxiliary top knife is matched with a dead knife motor through a dead knife motor belt assembly, the dust removal device comprises a vacuum suction system and a paper-dust separating device, the vacuum suction system is connected with the paper-dust separating device through a vacuum pipeline, the paper-dust separating device is internally provided with a paper-dust filter, and the vacuum suction system is provided with a plurality of sets of dust removal nozzles. A slitting knife reduces paper powderand paper wool from the source, and consumption of the slitting knife can be reduced; and the problem of printing leaky white, caused by the paper powder and the paper wool, of a product is reduced, and the printing effect is better.

Description

【Technical field】 [0001] The invention relates to the technical field of papermaking machinery, in particular to the technical field of a paper machine rewinding and slitting device and a dust removal system thereof. 【Background technique】 [0002] The design of the conventional rewinding machine is unreasonable, the condition of the cutting knife is poor, the upper knife switch is not designed with an air cylinder or the air cylinder is designed, but the air cylinder is blocked by the paper powder generated during the slitting process, and the top knife is difficult to move in and out. In order to ensure that the paper can not be cut Without manual propulsion, it is tightly fastened to the bedknife, resulting in excessive wear of the blade; in addition, due to the unreasonable design of the bedknife motor, the motor bearing is easy to wear and needs to be replaced frequently, and there is a large vibration during operation, so that It also drives the bottom knife to vibrate...
