AI Technical Summary
The existing pencil manufacturing process is wasted wood and the pencil board is prone to twist, warping or cracking during drying.
The single-piece wooden pencil board is sawed into two single-sided wavy pencil boards with a width of less than 2.5 mm in the cross-section direction of the single-piece wooden pencil board. The two wavy planes are in harmony, reducing the planing wood materials and improving deformation problems during the drying process.
While maintaining the shape of the pencil, it saves wood materials and effectively prevents the pencil board from twisting, warping or cracking during drying, improving the quality of the pencil's finished product.

Abstract
Description
Technical Field
[0001] The present application relates to a wooden pencil board for making pens and a pencil thereof, and in particular to a processing method of a wavy pencil board capable of saving wood and a pencil thereof. Background Art
[0002] The existing blanks used for manufacturing pencils, sketch pens, colored pencils, eyebrow pencils, etc. are mostly made of wooden flat plates with flat surfaces on both sides. When manufacturing finished pen tools, as shown in FIG15, two pen plates are clamped with a number of pen cores and glued together, and then a number of grooves are planed on the flat pen plate by planing or other methods to determine the shape of a single pen holder, and the pen holder is divided into a single pen body. The disadvantage is that no matter whether the pen body is made of a hexagonal rod, a triangular rod, a round rod, etc., a lot of wood must be planed on the flat pen plate to make the shape of the pen holder. Take a triangular rod pencil as an example: as shown in FIG15, when manufacturing a triangular rod pencil, its shadow part must be planed off, which will waste materials.
[0003] As shown in FIG. 16 , A is the material usage of two pencil plates in the prior art, and B is the material usage of two wavy pencil plates, and B obviously uses less material than A.
[0004] Therefore, as shown in Figures 3, 7, 11, and 15, if the two non-adhesive surfaces are prefabricated into a shape similar to a pencil (i.e., the shape of multiple pencils arranged), the material requirements for making pens can be met and some wood can be saved, which is both cost-effective and environmentally friendly.
[0005] However, the pencil board of the prior art is cut piece by piece by a cutting knife. If the wood is directly cut into a wave-shaped thin plate by a cutting knife, the pencil board will show peaks and troughs. Because the troughs are thin, improper cutting is prone to cracking and breaking. In addition, in order to facilitate cutting, the wood used is a wood with a high moisture content caused by boiling. Because the wavy pencil board has peaks and troughs, it is uneven in thickness. Therefore, the cut pencil board is prone to twisting, warping and even cracking during the drying process due to its uneven thickness. In addition, the cut pencil board is a raw board. It is hard and difficult to be rolled when directly made into a pencil. It will often go through the process of soaking in liquid medicine, high-temperature boiling, and drying to make a finished board. This absorbs water and dries again, which is more likely to cause twisting, warping and even cracking. Summary of the invention
[0006] The previous object of the present application is to provide a method for processing a corrugated pencil board that can save wood, such as Figure 1, as shown in FIGS. 5, 9, and 13, in the cross-sectional direction of the prepared single-piece wooden pencil board, a saw blade with a width less than 2.5 mm is used to saw it along a broken line or a curved path into two wavy pencil boards with a single-sided wavy shape. In this way, as shown in FIGS. 3, 7, 11, and 15, the planes of the two wavy pencil boards with a single-sided wavy shape are combined, and the outward wavy surface is similar to the shape of the pencil and is suitable for planing using the existing process, and the material that needs to be planed in the prior art is saved in the wave trough part.
[0007] Therefore, under the premise of applying the existing manufacturing process for pencil bodies, this design saves wood.
[0008] Another object of the present application also provides a pencil made of a wavy pencil board obtained by the processing method of a wavy pencil board capable of saving wood.
[0009] To achieve the above object and better interpret the present invention, the present application provides the following technical solutions.
[0010] For the technical solution of the previous object of the present application, a processing method of a wavy pencil board capable of saving wood, including a wooden pencil board, is characterized in that: in the cross-sectional direction of the single-piece wooden pencil board, a saw blade with a width less than 2.5 mm is used to saw it along a broken line or a curved path into two wavy pencil boards with a single-sided wavy shape.
[0011] For the technical solution of the latter object of the present application, a pencil includes a pen body that fixedly wraps a pen core, and the pen body is made of a wavy pencil board obtained by the processing method of a wavy pencil board capable of saving wood. Description of the Drawings
