Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a perspective view of an eco-friendly recycled paper pencil according to an embodiment of the present invention, Figure 2 is a schematic structural diagram of a manufacturing apparatus of an eco-friendly recycled paper pencil according to an embodiment of the present invention, Figure 3 is an embodiment of the present invention According to the flowchart of the manufacturing method of eco-friendly recycled paper pencil.

Referring to these drawings, but mainly referring to FIG. 1, the eco-friendly recycled paper pencil 1 of the present embodiment includes a shim 2 made of graphite and a recycled paper provided on the outside of the shim 2 and absorbing grass. ) Is made of a body (3) formed by drying and after processing combined with. Eco-friendly recycled paper pencil (1) shown in Figure 1 is a finished pencil.

Here, the recycled paper constituting the body 3 may be a general newspaper, but is not necessarily so. That is, any paper can be used as the material of the body 3 as long as it can be used as recycled paper such as newspaper. For example, paper such as general thick cardboard, books, or magazines may be used as recycled paper.

The method for producing a recycled paper pencil according to the present invention is characterized in that the recycled paper manufactured using a paper having a weight of 45-130 g / m 2. The unit "g / m 2" here means the weight per unit area of the paper. Generally, when newspaper or paper of less than 45g / m² is used as the material of the body (3), the paper breaks before it is rolled up, and if it is too heavy (thick), that is, if it exceeds 55g / m², the grass penetrates into the paper. Although the adhesion between the papers is very low and the defect rate is not high, the manufacturing method of the eco-friendly recycled paper pencil according to the present invention may use recycled paper exceeding 55g / m 2, because the ultrasonic absorption method is used. This is because there is a feature of the present invention in that the treatment can be carried out to a weight of 130 g / m 2. The average pencil lead is about 2mm in diameter and the art pencil is about 3-4mm.If you use a 2mm pencil lead, 110g / ㎡ paper will be used, and if you use a thick lead about 3-4mm, 130g / ㎡ paper will also be ultrasonically glued. The absorption method can be used. If it exceeds 130g / m2, the center seam and the part where the paper is first bonded are not tightly adhered to each other, which causes the problem of moving the seam later, which is the same as the situation where it is hard to roll the thin seam on a thick paper. to be.

In producing the body 3 using recycled paper such as newspaper, the color may be black and white, such as white or black, or a color material. In the latter case, colorful pencils may be produced.

According to the eco-friendly recycled paper pencil (1), since the body (3) is manufactured using conventional recycled paper away from the conventional wood material, as in the prior art, it helps to weaken the problem of global desertification and environmental pollution by logging. On the other hand, it is possible to secure safety from the harmful effects of the human body due to the use of chemical adhesives, and to feel a little light while forming a soft skin, thereby improving the writing feeling and feel according to the excellent grip, and further providing a sweat absorption effect. Not only can the cutting work of the body (3) can be convenient, so as to improve the practical value and enhance the dignity as a product. When the body 3 is carved out, the carved by-product becomes newspaper.

For reference, in FIG. 1, the holder 4 is further coupled to the rear end of the eco-friendly recycled paper pencil 1, and the eraser 5 is coupled to the holder 4, but such a structure covers the scope of the present invention. There is no limit. In other words, even a pencil without the holder 4 and the eraser 5 may extend the scope of the present invention.

Next, an apparatus and a manufacturing method of the eco-friendly recycled paper pencil 1 shown in FIG. 1 will be described with reference to FIGS. 2 and 3.

The primary pencil manufacturing unit 10 rolls the recycled paper, which is the material of the body 3, to the outer surface of the shim 2 made of graphite, and combines the shim 2 and the recycled paper first to produce the primary pencil 1a. Play a role. In order for the primary pencil 1a to be manufactured, first, a recycled paper, which is a material of the core 2 and the body 3 made of graphite, must be provided, and their length, thickness, or area are also pre-processed. Should be.

For reference, newspapers may be the most common in selecting recycled papers, but as described above, it is sufficient if recycled papers that can correspond to newspapers are not newspapers. The manufacture of the primary pencil 1a may be performed by a worker's hand, or may be automatically performed by an automated machine.

Pull-in recycled paper roll The conveyor 20 serves to manufacture the secondary pencil 1b by putting together the primary pencil 1a and the recycled paper which absorbed the grass together. To this end, the other recycled paper is immersed in a predetermined bucket so that the recycled paper absorbs the grass, and then the pool-loaded recycled paper is fed to the conveyor 20 together with the primary pencil 1a and the recycled paper absorbed by the grass, and then the secondary pencil 1b. ) Can be prepared. Of course, the production of the primary pencil (1a) and the production of the secondary pencil (1b) may be implemented such that the full input recycled paper proceeds at the same time continuously through the conveyor 20.

Here, the process of soaking the other recycled paper in the predetermined bucket to absorb the grass is preferably performed by the ultrasonic absorption method, the ultrasonic absorption method is different depending on the paper thickness when the recycled paper is immersed in the predetermined bucket Put a mixture of 80% starch grass and 20% resin pool in an ultrasonic tube and soak it for about 5-15 seconds and use ultrasonic waves to allow the grass to penetrate into the molecular structure of the paper evenly. This will soften the recycled paper and prevent it from becoming loose or sticking when rolling. This ultrasonic absorption process has been experimented to be able to obtain a firmer adhesion without failure in the manufacture of recycled paper pencil.

When the feed-in recycled paper sheet is briefly examined for the conveyor 20, the feed-in recycled paper sheet conveyor 20 includes a main body portion 21, conveyor belts 22a and 22b, a pull-in portion 23, and recycled paper. The part 24 is provided.

Here, in the case of forced drying, any of wet or dry heating may be applied.

More briefly on drying, the reason why the natural drying and forced drying are actually used may be the reasons mentioned above, or the first natural drying is performed so that the secondary pencils 1b attached to the outside do not stick to each other, When the drying is completed and the secondary pencils 1b do not stick to each other, it may be the reason that the forced drying is performed by using a machine such as an oven. Even for the latter reason, only natural drying or forced drying may be performed. However, when forced drying is combined, the grass can fly faster and solidify more hardly, and it can also serve to burn off any unnecessary or bad ingredients that may be present in the grass. can see. If you are doing both natural and forced drying, it may vary slightly depending on the weather, sunshine, and wind, but approximately 24-72 hours of natural drying followed by 3-6 hours of forced drying at 110 degrees Celsius. Can be.

Finally, the post work unit 40 serves to manufacture the finished pencil 1 shown in FIG. 1 by performing a post work on the secondary pencil 1b.
