The utility model relates to a wood plastic material pencil and pencil board, which belongs to the cultural category. The pencil board refers to wood plastic material on the upper surface of the substrate is provided with a strip of at least two convex ribs arranged in parallel, lower surface of the wood plastic material substrate, a lead groove corresponding to each strip convex ribs and convex edges along the length direction, the lead groove was positively semicircle, the center line of lead the core groove of the center line is parallel to the strip convex edge, and in the same vertical plane. The utility model pencil board of wood plastic material, can use the existing production technology of wooden pencil, which can maximize the protection of the \crust\ layer is not damaged, and then make the wood pencil pencil board in the forming process of the stiffness and hardness is not affected by the loss of wood pencil greatly improve productivity and reduce production cost. The utility model has the advantages of reasonable design, simple structure and full consideration of the property and characteristics of the wood plastic material, and optimizes the technological part of the traditional pencil production process which is not suitable for the production of wood plastic material.

木塑材料鉛筆筆板
本技術(shù)涉及一種木塑材料鉛筆筆板,屬文化用品類。
技術(shù)介紹
傳統(tǒng)鉛筆的主要生產(chǎn)原料是木材,據(jù)資料顯示:全世界每年用于生產(chǎn)鉛筆所消耗的木材多達(dá)幾百萬(wàn)立方米。隨著全球氣候變暖,節(jié)能減排,保護(hù)森林樹木已成為世界各國(guó)的當(dāng)務(wù)之急。為此,世界上的一些著名的大型鉛筆生產(chǎn)企業(yè)相繼開(kāi)展了以木塑材料替代木材生產(chǎn)鉛筆的研發(fā)和推廣工作。由于木塑材料和木材的材料屬性差異,致使木塑材料不能直接按照傳統(tǒng)木質(zhì)鉛筆現(xiàn)有的生產(chǎn)工藝及生產(chǎn)設(shè)備進(jìn)行生產(chǎn)。傳統(tǒng)木質(zhì)鉛筆生產(chǎn)的產(chǎn)品基本成型工藝是根據(jù)鉛筆的不同規(guī)格,先制作成相應(yīng)規(guī)格的筆板,筆板通常為平板狀,再將筆板置于鉛芯刨槽機(jī)上刨出8---9條正半園型的鉛筆芯槽,再在開(kāi)出鉛筆芯槽的表面涂膠,將鉛芯置入凹槽內(nèi),將另一塊同樣開(kāi)有鉛筆芯槽的筆板與之沾合成一體,待膠水徹底干燥后,將沾合好的筆板沿鉛筆芯分割成8---9根帶有鉛芯的方條型鉛筆,最后將帶有鉛芯的方條型鉛筆置于鉛筆外型機(jī)上車出所需要的圓形、六邊形型、三角形等不同形狀的鉛筆。然而,當(dāng)我們使用木塑材料制作成平板狀鉛筆筆板時(shí),再按照上述傳統(tǒng)木質(zhì)鉛筆生產(chǎn)成型工藝制作出來(lái)的鉛筆,其挺度,硬度幾乎全失,而不堪使用。其根本原因是,木塑材料產(chǎn)品的基本成型工藝是將材料的各種成分充分?jǐn)嚢韬螅?50度左右的溫度下進(jìn)行融合,再將融合好的材料通過(guò)產(chǎn)品定型模具,冷卻模具擠出成型的。產(chǎn)品在冷卻的過(guò)程中,與冷卻模具接觸的一面會(huì)迅速形成一0.05--0.1mm厚的“結(jié)皮”層。該“結(jié)皮”層具有良好的挺度和硬度。因此,用單支擠出成型的木塑材料鉛筆與用木材制作的傳統(tǒng)鉛筆相比,其挺度和硬度基本上沒(méi)有差異。而用木塑材料制作成 ...
