Abstract
The invention discloses a kind of printing paper machinery de-inking method and its device, one group drives connecting gear action by the drive mechanism that motor and decelerator form, and drives paper to advance.Simultaneously another group drives the action of sbrasive belt grinding mechanism by the drive mechanism that motor and decelerator form, grinding belt is contacted with paper, remove the ink marks of paper using tribology principle, reach the effect of paper deinking, paper is reused, energy saving, reduces cost and the pollution that waste paper reclaims.
Description
Technical field
The present invention relates to a kind of deinking terminal, particularly to a kind of printing paper machinery drubber.
Background technology
In the middle of daily office process, for the process of paper in the office, we generally adopt two ways.One kind is right
Concerning security matters paper is directly pulverized with pulverizer；One kind is to sell waste paper.However, both approaches all cause the very big wave of paper in the office
Take.Typically conclude whether the ink marks that the standard whether a paper can reuse is attached to above paper can be revealed,
Whether have impact on secondary use, rather than paper itself, if the separation of paper and ink marks can be realized, paper just can be realized
Recycling.Recycled writing paper technology general at present is mainly focused on waste paper and reclaims back deinking reproduction after processing factory, this
One process of sample needs to expend the resources such as substantial amounts of human and material resources and financial resources, causes certain air pollution and water dirty simultaneously
Dye, also creates much unnecessary Financial cost during transport and deinking simultaneously.The application is conceived to and evades these
Problem is it is intended to advance in the middle of daily life the deinking regeneration of paper, that is, directly real in office or big printing factory
The deinking of existing paper recycles.According to retrieval, existing paper deinking device at present, such as：Application No. 200980159725.2
A kind of de-inking method of Chinese patent application, uses traditional floatation, and by comparison, the application breaches traditional waste paper and returns
Receive the restriction of recycled paper it is not necessary to the operation of factory's formula, the deinking work of paper can be carried out in office, floor space is little, raw
Produce low cost, save a series of expense such as space expenses, labour cost, charges for water and electricity, and cause during also avoid floatation
Water pollution problems, there is higher environmental protection income；Working cycle is short, overcomes the cycle of traditional waste paper recycling of knowing clearly long
The drawbacks of；The device small volume and less weight of the application, simple to operate, target group's scope is wide.And for example Application No.
The Chinese patent of 201210574470.X, using the deinking process for waste paper of mixed enzyme, but compared with the application, still without breaking away from
The pattern of traditional deinking, the application operation does not need the paper to carry out deinking in the environment of water, it is to avoid the wave of water resource
Take and traditional inevitable water pollution problems of paper making industry.The application not only can save substantial amounts of paper, can also reduce perhaps
Many indirect energy consumptions and pollution.The waste causing especially for the paper destruction of office, the application rises to paper destroyer
Effect to a replacement.

Rotate, thus driving abrasive band driven pulley tensioning to rotate.So far, the grinding mechanism of drubber and connecting gear start running.
Paper is put at device portal, because the surface roughness of conveyer belt and coefficient of friction are big, conveyer belt can carry
Dynamic paper advances, and paper will not occur relative motion with conveyer belt, and paper moves to grinding mechanism with conveyer belt,
Now, grinding belt and paper are in close contact, and the coefficient of friction due to conveyer belt and paper is more than or equal to grinding belt and paper
Coefficient of friction, paper will not because of the action of grinding belt with conveyer belt occur relative motion.And due to two motors
Turn to contrary, come from conveyer belt and the frictional force of grinding belt suffered by paper are in the same direction it is not easy to depart from conveyer belt.Mill
Cut abrasive band to rotate, paper when contacting with grinding belt, based on tribology principle, can be gone by grinding belt by the ink marks friction on paper
Remove, being advanced slowly with paper, the friction of entire paper can progressively be finished by abrasive band, now, paper can be with the fortune of conveyer belt
Move and be sent from device outlet.
