Description

Web powder removing device of rotary press
Technical Field
The invention relates to the technical field of paper powder removal of rotary printers, in particular to a paper powder removal device for a web of a rotary printer.
Background
The web used in the existing rotary press has various types of paper such as white cardboard, newsprint, double offset paper and the like, and paper dust exists on most of the surfaces of the paper during the manufacturing process of the web.
The common rotary press comprises a printing plate roller, a rubber roller and an embossing roller, and when the rotary press works, paper passes between the rubber roller and the embossing roller, patterns are transferred to the rubber roller by the printing plate roller and then transferred to the paper by the rubber roller. Because paper powder exists on the surface of the paper, the paper powder can be stuck to the rubber roller. Along with the accumulation of paper powder, defects are generated on the printed matter, waste products or defective products are generated, the quality of the printed matter is seriously affected, and at the moment, the rubber roller needs to be cleaned with time and manpower, so that the efficiency is reduced. The rotary ink-jet printer has no printing roller, rubber roller and embossing roller, no paper powder is adhered to the rubber roller, and the rotary ink-jet printer is equipped with ink-jet head. However, the rotary inkjet printer has a disadvantage in that a plurality of inkjet heads are required to be installed in each inkjet printer, and the requirements for the inkjet heads are very high, and any one of the inkjet heads cannot be blocked during the inkjet process, otherwise, the pattern ejected onto the paper may have defects. Because the ink-jet head of the rotary ink-jet printer is very close to the paper when ink is jetted, and the air flow can drive the paper powder on the surface of the paper to fly when the paper runs, the ink-jet head can be blocked by the stirred paper powder, and the quality problem of the printing is caused.
In order to avoid cleaning the rubber roller and avoiding the paper powder from blocking the ink-jet head, the paper powder of the roll paper is required to be cleaned, chinese patent application No. 201320469856.4 discloses a paper powder cleaning device of a rotary printing machine, the upper surface paper powder is cooperatively removed by a rubber roller and a bottom roller, the paper powder on the surface of the rubber roller is removed by a sticky roller, and the paper powder on the surface of the sticky roller is removed by a hairbrush arranged in a water tray, so that the paper powder removing effect is poor, as the paper powder is light and easy to float, only one surface paper powder can be removed, the paper powder is not removed cleanly, the paper is easy to wet by the hairbrush, the printing effect is influenced, the distance between the rubber roller and the bottom roller is not adjustable, and the paper penetration difficulty occurs in the paper penetration process; chinese patent application No. 201420258463.3 discloses a device for removing paper powder from an impression cylinder of a rotary press, which removes carbon-coated material on the surface of the impression cylinder by a nylon plate, directly cleans the surface of the impression cylinder, and cannot remove paper powder, and the paper powder is stuck on a rubber roller to affect printing effect; a web dust removal device for a rotary press has been proposed to address the above-mentioned problems.
