Description
本創作係有關於一種三維紙塑製品製造設備，特別是指一種具零拔模角之三維紙塑製品製造設備。 This creation is about a three-dimensional paper-plastic product manufacturing equipment, especially a three-dimensional paper-plastic product manufacturing equipment with zero draft angle.
紙漿模塑品(或稱紙塑品)係以紙漿為原料，利用成型模具吸漿並壓塑成型，其成品可以回收再製造，所以符合環保再利用之節能減碳趨勢。 Pulp molded products (or paper-plastic products) are made from pulp as raw materials, which are sucked and molded by a molding die. The finished products can be recycled and remanufactured, so they are in line with the trend of energy saving and carbon reduction.
然而，由於現有紙塑品之製程在成型模具進行擠壓或熱壓時，僅具有單一方向，即往下擠壓方向的力量，致紙塑品側邊的成型無法施加壓力，致造成以下問題：一、紙塑品底板與側版的密度不平均及厚度不同；二、由於模具脫模時，需要一拔模角度才能使紙塑品順利脫模，因此現有紙塑品的成品彎折處無法成為直角。 However, since the process of the existing paper-plastic product is extruded or hot-pressed in the molding die, only the force of the single direction, that is, the downward pressing direction, the molding of the side of the paper-plastic product cannot apply pressure, resulting in the following problems. : First, the density of the paper and plastic floor and the side plate are not uniform and the thickness is different; Second, because the mold is demoulded, a draft angle is required to make the paper-plastic product smoothly demould, so the finished product of the existing paper-plastic product is bent. Can't be a right angle.
為了解決上述問題，專利案號TW201711926提出一套技術方案，包含將紙漿材料形成一平面狀、擠壓並熱乾燥該平面狀的紙漿材料，使該紙漿材料形成具有複數折彎槽的紙漿品、取出該紙漿品、裁切該紙漿品周圍毛邊、及於各該彎折槽上膠、以及翻折各該彎折槽兩側相鄰的板部而可於彎折處形成為直角並固定成型。 In order to solve the above problem, Patent No. TW201711926 proposes a technical solution comprising forming a pulp material into a planar shape, extruding and thermally drying the planar pulp material, and forming the pulp material into a pulp product having a plurality of bending grooves, Removing the pulp product, cutting the burrs around the pulp product, and gluing the bending grooves, and folding the adjacent plate portions on both sides of the bending groove to form a right angle and fixing at the bending portion .
惟，前述雖可克服紙塑品密度及厚度不均勻、及紙塑品的成品彎折處無法成為直角的問題，但其技術手段主要源自於紙漿品彎折槽的裁切與黏合等工序。以製程而論，由於裁切與黏合之工序變得更為繁瑣，需耗費大量的生產與製造時間；對於製品本身，凡在彎折處採用大量的黏膠以黏合成為直角，致使整體的結構的強度受限，且黏合處亦顯得相對薄弱，仍待進一步改良。 However, although the above can overcome the problem that the density and thickness of the paper-plastic product are not uniform, and the bent portion of the finished product of the paper-plastic product cannot be a right angle, the technical means are mainly derived from the steps of cutting and bonding the bending groove of the pulp product. . In terms of process, since the process of cutting and bonding becomes more complicated, it takes a lot of production and manufacturing time; for the product itself, a large amount of glue is used in the bending to make a right angle, resulting in the overall structure. The strength is limited and the bond is also relatively weak and remains to be further improved.
本創作之目的，即在於提供一種具零拔模角之三維紙塑製品製造設備，提供紙塑製品欲形成直角彎折時無須透過以黏膠黏合的方式達成，而可透過直接成型，因此不僅能夠提升結構強度，亦可縮短工時與節省製造成本。 The purpose of this creation is to provide a three-dimensional paper-plastic product manufacturing apparatus with zero draft angle, which provides a paper-plastic product which is not required to be bonded by means of adhesive bonding, but can be directly molded, so that It can increase the structural strength, shorten the working hours and save manufacturing costs.
