Description
Technical field
The utility model relates to Waste Paper Recycle Technique field more particularly to a kind of paper pulp model 3D printing production systems
System.
Background technique
Shown according to available data, waste paper accounts for about 40% in whole world Papermaking fibers raw material at present, the dosage of the following waste paper and
It will sustainable growth than escheat.It expects 2010, world's waste paper consumption figure will be close to 225,000,000 tons.China is world's waste paper
Maximum importer and consumption big country, 40,170,000 tons of secondary stock consumption (being equivalent to 50,210,000 tons of waste paper) in 2007, wherein into
18,050,000 tons of secondary stock of mouth (being equivalent to 22,560,000 tons of waste paper).
But the case where current waste paper in China recycling, is less optimistic, the waste paper rate of recovery is only 20-30%, this is equivalent to every year
There are 6,000,000 tons of waste paper to be lost, there are 100 ~ 3,000,000 mu of forest reserves to be wasted.At this moment, how more we just face a problem:
Good utilizes generated waste paper in our daily lifes.Therefore applicant considers, if it is possible to design a kind of mould using waste paper
Type production system then one recycles waste paper data can be convenient, avoids wasting, and two can be used for educational research or one
The molder field not high to required precision a bit, realizes the recycle value of waste paper.
Model is prepared using waste paper and has precedent, and someone completes benefit for Electromechanical Engineering and Automation College, Shanghai Univ.
It with the precedent of paper pulp production model, but uses hand-made, i.e., prepares paper pulp first with waste paper, then utilize iron
Other objects such as silk produce mold core, and the mode for then reusing filling produces a paper pulp model, finally again by model into
Row baking.The shortcomings that this method is: one, production precision is not high, surfaces versus rough；Two, it can only make relatively simple
It is excessively high to complete difficulty for complex model for model；Three and human cost it is too high, manual operation there is also it is great accidentally
Difference；Four, defect ware is more, wastes raw material.But this manufacturing method also follows that we provide a thinkings, i.e., it will recycling
The waste paper come is made paper pulp and for modelling, and this production method is simple and people can complete at home, is not necessarily to
Waste paper is sent to recycle bin, so have stimulated people significantly using the interest of waste paper manufacture mock-up, while also promoting
Waste paper recycling.New methods in working is provided for the development and utilization of waste paper.
On the other hand, in current generation, 3D printing becomes important leading industry, also the multiple quilt in " made in China 2025 "
It emphasizes, is considered as breaking the important opportunity of increasing material manufacturing market " America and Europe takes the lead, and Asia is caught up with and surpassed " situation.Therefore production material multiplicity
Changing also becomes the most important thing with subject frontal generalization, and it is bright that the Ministry of Education has singly just issued official document twice later six months in 2017
Really requirement of the expression to middle and primary schools' 3D printing education.
Therefore applicant considers further that if 3D printing technique and waste paper model application combined, one may be implemented waste paper
Recycling, two can preferably improve waste paper model accuracy, reduce model preparation cost, and third also reduces 3D printing
The cost requirement of technology itself can be conducive to the popularization and application of 3D printing technique itself.
