Description

輕量化分條機刀套改良結構 Improved structure of lightweight slitter knife cover

本創作是有關分條機上用以固定分條刀位置的刀套結構，尤指一種輕量化且兼具強度與品質之輕量化分條機刀套改良結構。 This creation is about the structure of a knife sleeve used to fix the position of the slitting knife on the slitting machine, especially an improved structure of a lightweight slitting machine knife sleeve with both strength and quality.

一般用來將寬幅材料(如：金屬、布、紙及塑膠類等材質)切割成為多個窄幅材料的分條機(或縱剪機)，其分條機之刀軸結構乃如第1圖所示，主要係於一刀軸5上依切割需求同時套設複數圓形環狀之分條刀6，且於各分條刀6之間另套設各種符合切割寬度的刀套7(隔套、分隔套、分隔片)，使各分條刀6可以經由該等刀套7而被間隔固定在預設的切割寬度。 The slitting machine (or slitting machine) is generally used to cut wide materials (such as metal, cloth, paper, plastic and other materials) into multiple narrow materials. As shown in Fig. 1, a plurality of circular ring-shaped slitting knives 6 are set on a knife shaft 5 at the same time according to the cutting needs, and a variety of cutting sleeves 7 (( Spacers, separators, and separators), so that each of the slitting knives 6 can be fixed at a predetermined cutting width through the cutters 7 at intervals.

傳統的刀套7結構，有如第2圖所示，其主要係呈圓形環狀之結構體，該刀套7外周緣具有一外表側71，而刀套7內周緣設有一鍵槽73，以供利用一鍵與該刀軸5結合形成同步連動；而於該刀套7內周緣可依需要設有可減輕重量之內環槽74。 The structure of the conventional knife cover 7 is shown in Figure 2. It is mainly a circular ring structure. The outer periphery of the knife cover 7 has an outer surface 71, and the inner periphery of the knife cover 7 is provided with a key groove 73. One key is used to combine with the knife shaft 5 to form a synchronous linkage; and an inner ring groove 74 can be provided on the inner periphery of the knife sleeve 7 as needed to reduce weight.

上述此種結構，由於各分條刀6需能精準地定位於刀軸5上預定位置，使能精確地進行切割作業，往往需從兩側施予極大的作用力來 壓合刀軸5上的各分條刀6及各刀套7；因此，傳統各刀套7大多具有較厚實的結構，致使具有相當重的重量，舉例來說，外徑35公分、寬度5公分的刀套重量約有10公斤，外徑27公分、寬度5公分的刀套重量約有7.5公斤。如此一來，當技術人員在調整分條機的切割寬度時，在反覆裝設及拆卸各刀套7的過程中，往往需要花費大量的時間與體力，不但影響分條機的調整時間，亦降低產能效率。 In the above-mentioned structure, since each slitting knife 6 needs to be accurately positioned at a predetermined position on the knife shaft 5 to enable accurate cutting operations, it is often necessary to apply great force from both sides to Each split knife 6 and each knife holder 7 on the knife shaft 5 are pressed; therefore, most of the traditional knife holders 7 have a thick structure, resulting in considerable weight. For example, an outer diameter of 35 cm and a width of 5 A tool cover weighing about 10 kilograms weighs about 10 kilograms, and a tool cover with a diameter of 27 cm and a width of 5 cm weighs about 7.5 kg. In this way, when the technicians adjust the cutting width of the slitter, they often need to spend a lot of time and physical strength in the process of repeatedly installing and disassembling each knife cover 7, which not only affects the adjustment time of the slitter, but also Reduce productivity.

為改善上述缺失，在中華民國專利公告第I605893號發明案中揭露了一種輕化型刀套，其主要包含：一環形之刀套本體，該刀套本體具有一位於該環形結構內側且沿中心軸向延伸之內表面，以及一位於該環形結構外側且沿中心軸向延伸之外表面，於該刀套本體該內表面與該外表面之間分別垂直設有一第一側面及一第二側面，於該第一、二側面上分別設有複數個孔洞，藉以達到減輕該刀套本體重量的功效。 In order to improve the above-mentioned shortcomings, a lightweight knife cover is disclosed in the Republic of China Patent Publication No. I605893, which mainly includes: a ring-shaped knife cover body, the knife cover body has an inner side and a center along the ring structure. An axially extending inner surface and an outer surface extending outside the annular structure and extending axially along the center, a first side surface and a second side surface are provided perpendicularly between the inner surface and the outer surface of the tool holder body, respectively. A plurality of holes are respectively provided on the first and second sides to reduce the weight of the knife cover body.

然而，此種結構由於在該刀套本體二旁的第一、二側面上分別設置複數個孔洞，必然會直接影響該刀套本體二旁側的結構強度；在實際應用時，由於該刀套本體二旁側通常需承受約30噸的壓力來固定分條刀，因孔洞致使二旁側的受力面積減少、單位面積受力增加，相同材料強度的條件下，刀套本體更容易產生變形，而變形後的刀套本體無法再提供精確的間隔距離以固定各分條刀，即無法使用而必須汰換，雖達輕量化之目的但相對降低了使用壽命，形成應用上的極大缺失。 However, since this structure is provided with a plurality of holes on the first and second sides of the tool case body, it will inevitably directly affect the structural strength of the tool case body on the two sides; in actual application, due to the tool case The second side of the body usually needs to bear about 30 tons of pressure to fix the slitting knife. Due to the hole, the force area on the second side is reduced and the unit area force is increased. Under the same material strength, the blade body is more likely to deform. However, the deformed tool holder body can no longer provide accurate separation distances to fix the slitting knives, that is, it cannot be used and must be replaced. Although it achieves the purpose of weight reduction, it relatively reduces the service life and forms a great lack of application.

此外，上述輕量化之刀套本體，因孔洞或凹部繫屬二旁側表面，若吸附之碎屑未能完整清潔，操作時難免會因碎屑落入二側面而影響精度；再者，實務上不乏有刀套混合使用之情形，比如將上述開設孔洞之 刀套本體與無孔洞之傳統刀套混合使用，孔位的不對應將造成應力不均，容易於傳統刀套壓印出刻痕，或是在彼此接觸的表面產生毛邊，甚至於在分條刀的壓合部位造成刻痕或毛邊，都會對機件造成難以復原的損害。 In addition, the above-mentioned lightweight knife cover body, because the holes or recesses are on the two side surfaces, if the adsorbed debris is not completely cleaned, it will inevitably affect the accuracy due to the debris falling on the two sides; in addition, the practice There are many cases of mixed use of knife sleeves, such as The tool holder body is used in combination with the traditional tool holder without holes. The misalignment of the hole positions will cause uneven stress, which is easy for the traditional tool holder to emboss nicks, or cause burrs on the surfaces that are in contact with each other. A nick or burr caused by the pressing part of the knife will cause irreparable damage to the machine.

有鑑於習見之輕量化刀套結構有上述缺點，創作人乃針對該些缺點研究改進之道，終於有本創作產生。 In view of the above-mentioned shortcomings of the lightweight knife cover structure, the creator researched and improved these shortcomings, and finally created this creation.
