Paper regeneration device based on short pulse laser

Abstract

The invention provides a paper regeneration device based on short pulse laser. The paper regeneration device comprises a paper discharging mechanism, a paper conveying mechanism, a paper feeding mechanism and a cleaning mechanism; the paper discharging mechanism comprises a paper discharging shaft, the middle of the paper discharging shaft is sleeved with a plurality of paper discharging rollers,and the paper discharging shaft is driven by a motor to rotate anticlockwise to discharge paper; the paper conveying mechanism comprises paper pressing plates and a supporting plate, the plurality ofpaper pressing plates are arranged in a row, and the supporting plate is arranged above the paper pressing plates; a de-inking mechanism is arranged on the supporting plate and comprises an optical sensor used for sensing ink mark information on paper, a laser generator used for emitting laser and a Powell prism used for converting point-shaped light sources into linear light sources; the paper feeding mechanism is arranged behind the paper conveying mechanism and comprises a paper feeding plate, a paging support, a paging shaft and a paging roller; the cleaning mechanism comprises an electrostatic adsorption polar plate and a fan, the fan is used for blowing waste, and the electrostatic adsorption polar plate is used for adsorbing and collecting waste. Ink marks attached to paper are removed by selecting laser with specific wavelength.

Description

technical field [0001] The invention relates to the technical field of paper regeneration, in particular to a paper regeneration device based on a short pulse laser. Background technique [0002] In the use of paper, 70% of daily office printing documents are non-archive printing, which are discarded in the trash after a short period of use, which means that office printing paper will cause a lot of waste during use. [0003] The existing paper recycling technology refers to the production process in which waste paper is processed mechanically and chemically to separate impurities, retain fibers, make pulp, and make paper and cardboard. Its basic process includes eleven steps of waste paper collection and classification, dissociation, purification, screening, deinking, washing flotation, heat dispersion, bleaching, beating, papermaking and finished products. The paper made by the traditional paper recycling technology has the disadvantages of incomplete deinking, low whiten...
