BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 This is a schematic flow chart of a method for manufacturing a pen holder according to an embodiment of the present application. DETAILED DESCRIPTION

[0007] In view of the problem that existing plastic pen products are prone to cause harm to the environment and human body, the present invention provides a method for manufacturing a wheat straw pen, which uses wheat straw as a raw material to manufacture the pen, thereby avoiding various problems caused by plastic pen.

[0008] Wheat is a common crop, often used as a food for people. After wheat is harvested, the remaining wheat straw needs to be processed. The simplest way to deal with it is to burn it, but this method is very likely to lead to the emission of toxic and harmful gases such as sulfur dioxide, which affects air quality and causes environmental problems. As a renewable resource, wheat straw is produced in large quantities every year. Using wheat straw as a raw material to make pen holders has a series of advantages such as easy collection and low cost. In addition, wheat straw is very environmentally friendly and can avoid the problems that may arise in the production and use of the above-mentioned plastic pen holder products, thereby achieving sustainable utilization of resources and ultimately protecting the environment and human health.

[0009] Embodiment 1

[0010] Figure 1 A schematic flow chart of a method for manufacturing a pen holder according to an embodiment of the present application is shown. Figure 1 As shown, the method includes the following steps 1 to 6.

[0011] Before step 1, you need to select wheat straw raw materials. Try to choose wheat straw with a clean and smooth surface, uniform thickness, and no black spots, pests, or damage. Try to choose fresh wheat straw of the season as the main raw material. Generally, wheat straw after the wheat straw harvest season is the freshest and is the preferred wheat straw raw material. When selecting wheat straw raw materials, you should pay attention to the following points:

[0012] 1. Observe the color of the straw surface: Observe the color of the straw surface and choose straw with bright golden color;

[0013] 2. Check the integrity of the wheat straw: ensure that the whole wheat straw is intact and undamaged. Partial breakage of the wheat straw may affect the subsequent processing of the raw materials;

[0014] 3. Evaluate the overall texture of the wheat straw: feel whether the texture of the wheat straw is flat and smooth, and remove the straw with thorns or rough surfaces.

[0015] Only wheat straw that meets the above three points can be used as pen material.

[0016] A method for manufacturing a pen holder according to an embodiment of the present application begins with step one.

[0017] Step 1: washing the wheat straw to soften the wheat straw and separate the impurities contained in the wheat straw.

[0018] Wash the selected wheat straw thoroughly with clean water to soften it, separate the impurities contained in it, and remove the dust on the surface. The details are as follows:

[0019] 1. Soak the wheat straw in water: Put the wheat straw in a container, add enough water and soak it for a period of time until the straw is softened and the black impurities on the surface are lightened;

[0020] 2. Wash the wheat straw: Wash the soaked wheat straw with water, repeat the washing process several times until the black impurities on the surface of the wheat straw are basically invisible. For the black impurities that still exist after soaking and washing, you can use a brush to scrub the surface of the wheat straw.

[0021] Step 2: Dry the washed wheat straw.

[0022] The washed wheat straw needs to be aired or dried until the surface of the wheat straw is completely dry. The details are as follows:

[0023] For wheat straw that needs to be kept dry, choose a well-ventilated environment to dry it. You can place it in a breeze for drying. Be careful to avoid direct sunlight on the straw, which may cause the straw to fade or become hard.

[0024] Turn the straw regularly to avoid the situation where the sunlight only shines on one side of the straw, causing uneven surface drying and local moisture.

[0025] Since the drying time is long, you can also choose to dry the wheat straw by drying. When drying, pay attention to setting the drying time and drying temperature.

[0026] Step 3: Split the dried wheat straw in the middle, press it into thin sheets, and scrape off the inner film.

[0027] After the wheat straw is air-dried or dried, when the surface is dry, you can use scissors or other tools to split the wheat straw in the middle, press it into thin sheets, and scrape off the internal film. The details are as follows:

[0028] When preparing tools such as scissors, make sure the blades are free of impurities to prevent contamination of the straw surface. Make sure the blades are sharp and can cut the straw relatively completely to prevent damage to the integrity of the straw.

[0029] During the splitting process, after the scissors blades penetrate into the hollow part of the straw, gently split the straw, but do not slide the blades quickly to prevent the straw from being damaged;

[0030] After splitting the straw, you can first use your palm to push the straw on a flat surface, or use a roller-like tool to flatten the straw. There may be a layer of transparent film on the surface of the straw. You can use the blunt side of the blade to gently scrape off the film along the surface, which can also flatten the straw.

[0031] Step 4: Grind the wheat straw with the inner film scraped off to obtain ground wheat straw.

[0032] The dried wheat straw strips are ground into powder by a machine, and then the powdered wheat straw with uniform particle size is screened out with a sieve to remove fine impurities. The powdered wheat straw with larger particles can be repeatedly ground until the particles become uniform and fine.

[0033] Step 5: Use a mold to shape the ground wheat straw to obtain a wheat straw pen holder.

[0034] Mix the ground wheat straw with a suitable binder until a uniform and plastic mixture is formed. Fill the mixture into the cylindrical mold, fill and compact it fully with a scraper or other tool, and remove the wheat straw mixture from the mold after the curing time is reached.

[0035] Step six: grinding and polishing the straw pen holder to complete the production of the pen holder.

[0036] The finished straw pen barrel is polished and polished to remove excess edges or burrs, ensuring that the straw pen barrel has no thorny edges and a smooth surface. To protect the pen barrel and increase its gloss, a layer of varnish or natural wax can be applied. Varnish can be clear or colored, while natural wax usually provides a natural gloss and touch. The specific polishing operation is as follows:

[0037] 1. Preparation: Prepare a soft brush, sponge or other special polishing tools, and make sure the tools are clean and free of impurities. Before polishing, thoroughly clean the surface of the straw pen holder to ensure that there is no dust and oil to avoid affecting the polishing effect, and perform a small area of ​​polishing test on the surface of the straw pen holder to ensure that the selected material and polishing method are suitable for the straw pen holder.

[0038] 2. Apply: Apply varnish or wax evenly on the surface of the straw pen, then use a brush or sponge to gently apply it, taking care not to miss any area and avoid bubbles or accumulation. Use appropriate application techniques according to the viscosity and characteristics of the glazing material.

[0039] 3. Post-treatment: After the application is completed, place the straw pen holder in a well-ventilated and dust-free environment to dry naturally. The drying time depends on the materials used and the environmental conditions. After drying, it is necessary to check whether the coating is uniform and whether there are any omissions or uneven areas. If necessary, a second application can be made to achieve the desired gloss effect. For some varnishes or waxes, light grinding and polishing are required after drying to remove minor surface defects and make the straw pen holder smoother and brighter.

[0040] Finally, depending on the design, decorative patterns or text can be added to the pen barrel, which can be achieved by branding or gluing small pieces of dyed straw. The specific methods are as follows:

[0041] 1. Material preparation: Cut the flat wheat straw according to the designed decorative pattern or text, and color it after cutting. According to the size requirements of the pencil rod, cut the dyed and smoked wheat straw into a size and length suitable for decoration.

[0042] 2. Pasting and branding: The colored straw needs to be pasted in the next step. When pasting, you need to use an appropriate amount of environmentally friendly glue or adhesive to accurately paste the dyed straw piece to the designed position. At the same time, pay attention to controlling the amount of glue to avoid overflow and affect the overall appearance. At the same time, because branding can create lasting lines and patterns, it can be branded at the appropriate position of the pen holder. The temperature and pressure of the soldering iron need to be accurately controlled to prevent the pen holder from being burned.

[0043] 3. Detail adjustment and final inspection: Before the decorative elements dry, check and adjust their position to ensure the accuracy and beauty of the pattern or text, trim any excess edges, and ensure a natural and smooth transition between the decorative elements and the surface of the pen. Clean the surface of the pen to remove any residue or fingerprints that may have been produced during the decoration process to achieve the best decorative effect.
