Embodiment 1

[0041] Figure 1 to Figure 13An embodiment of the waste paper recycling device of the present invention is shown. The waste paper recycling device includes a paper feeding mechanism 1 connected in sequence, a paper grinding mechanism 2 for grinding ink on the surface of the waste paper, and a paper grinding mechanism 2 for grinding the surface of the waste paper. The spraying mechanism 3 for spraying, the compacting and drying mechanism 4 for compacting and drying the pulp on the waste paper, and the paper output mechanism 5 for exporting the recycled paper in the compacting and drying mechanism 4, the spraying mechanism 3 A pulp making mechanism 6 is connected. The paper making process using this waste paper recycling device: firstly, put the waste paper into the pulp making mechanism 6 for pulping, and the pulp making mechanism 6 supplies pulp to the spraying mechanism 3; secondly, the whole waste paper is fed into In the paper grinding mechanism 2, the ink on the surface o...

Embodiment 2

[0056] A paper making method of a waste paper recycling device, comprising the steps of:

[0057] S1: Pulping: put the waste paper into the pulping mechanism 6 for pulping, and the pulping mechanism 6 supplies pulp to the spraying mechanism 3;

[0058] S2: Grinding ink marks: the whole waste paper is fed into the grinding mechanism 2 through the paper feeding mechanism 1, and the surface ink marks are removed;

[0059] S3: Shotcrete: the waste paper after the surface ink is removed is sent to the spray mechanism 3, and the surface layer of the waste paper is sprayed;

[0060] S4: compacting and drying: the paper after spraying on the surface layer is sent to the compacting and drying mechanism 4, and the pulp on the waste paper is compacted and dried to form recycled paper;

[0061] S5: exporting: the recycled paper in the compacting and drying mechanism 4 is exported through the paper output mechanism 5 .

[0062] This paper making method forms recycled paper by first grindin...

Abstract

The invention discloses a waste paper regeneration device. The waste paper regeneration device comprises a paper feeding mechanism, a paper grinding mechanism used for grinding away ink marks on the surface layer of waste paper, a pulp spraying mechanism used for spraying pulp on the surface layer of the waste paper, a compacting and drying mechanism used for compacting and drying paper pulp on the waste paper and a paper discharging mechanism used for guiding recycled paper in the compacting and drying mechanism, wherein all the mechanisms are sequentially connected, and the pulp spraying mechanism is connected with a paper pulp making mechanism. The invention further discloses a paper making method. The method comprises the following steps that waste paper is put into the paper pulp making mechanism for pulping; a whole piece of waste paper is fed into the paper grinding mechanism through the paper feeding mechanism, and surface layer ink marks are ground away; the waste paper with the ink marks on the surface layer being ground off is conveyed into the pulp spraying mechanism, and pulp spraying is conducted on the surface layer of the waste paper; the paper with the surface sprayed with the pulp is conveyed into the compacting and drying mechanism, the paper pulp on the waste paper is compacted and dried, and recycled paper is formed; and the recycled paper in the compacting and drying mechanism is guided out through the paper discharging mechanism. According to the waste paper regeneration device and the paper making method thereof, production cost can be lowered, pollution can be reduced, and waste paper regeneration efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of waste paper recycling equipment, in particular to a waste paper recycling device and a papermaking method thereof. Background technique [0002] Paper is closely related to human life, we don't need paper all the time. And the pollution caused by paper is more and more not to be underestimated. With the development of science and technology, printers and printing paper have gradually replaced people's complicated hand-copying work and become a great assistant for people's office work. Most of the printing paper that has printed text is discarded after being used once. With the development of material culture, there are more and more printing papers. It will not only pollute the environment, but also cause a large number of trees to be cut down. According to the latest statistics, the global paper production and consumption in 2018 has reached 410 million tons, and nearly 2.9 billion big trees have dis...
