五、新型說明： 【新型所屬之技術領域】 本創作係關於一種印刷用的轉印輪具，尤指一種具高 含墨量及高轉印率之轉印輪具。 【先前技術】 請參閱第六圖所示，係一種刮刀控墨式的彩色印刷機 組架構圖，其中該刮刀控墨式的彩色印刷機組（30)包含有： 一墨槽（31)’用以儲存印刷用墨料於其中； 一轉印輪具（32)，係設置對應該墨槽（3彳）位置，令其 表面可沾染該墨槽（31)中的印刷用墨料，又該表面上形成 有圖案層（321 )，將印刷用墨吸納於其中； 一到刀（33)，係設置該轉印輪具（32)外側一適當位置， 令刮刀（33)接觸該轉印輪具（32)的表面； 一版輪具（34)，其表面上形成有凸版（341)，並係與轉 印輪具（32)接觸； 一壓力輪具（35)，係設置該版輪具（34)的外側一適當 位置，與版輪具（34)接觸提供該版輪具（34)與轉印輪具（32) 的接觸力，又待印刷物（60)係夾設於該版輪具（34)與壓力 輪具（35)之間。 上述彩色印刷機組（30)轉動時，該轉印輪具（32)的表 面因為形成有圖案層（321)，-旦開始轉動時，該圖案層（321) 會經過墨槽（31)而將墨吸納於其中，又該圖案層會與 版輪具（34)的凸版（341)接觸，而順利地將圖案層的墨轉印 3 M378835 至該版輪具（34)與壓力輪具（35)之間的待印刷物（6〇)上，以 完成轉印。由於轉印輪具（32)—側設有到刀（33)，因此轉 印輪具（32)轉動時該刮刀（33)會將其圖案層（32彳）多餘的墨 到除，能有效控制轉印輪具（32)的含墨量，確保將圖案至 待印刷物（60)上的上墨均勻度。 雖然刮刀（33)能控制轉印輪具（32)的含墨量，但由於 •到刀（32)長時間與高速轉動的轉印輪具（32)圖案層（321)接 -觸而會彼此磨耗。凊配合參閱第七圖所示，係為一種斜 _ 直條紋圖案層（321)，即該轉印輪具（32)的圖案層（321)係 形成有螺紋，請再配合參閱第八圖所示，係為該斜直條紋 圖案層（321)的縱剖圖，該斜直條紋圖案層（321)由轉印輪 具上的陶瓷層，以雷射雕刻複數道V型斜槽（322)所構成， 因此任兩相鄰V型斜槽（322)的槽壁（324)厚度是由外至内 漸增。如此一來，當圖案層（321)長時間與到刀（33)摩擦接 觸時，槽壁（324)頂部會向内逐漸磨耗，令原本用以吸納墨 •料於其中的V型斜槽（322)容量會變少，且v型斜槽（322) 等的開口（323)變大，而無法提供精準的印刷功能。 因此’目前有已有一種蜂巢式轉印輪具被提出，請參 閱第九A圖所示，即該轉印輪具的圖案層（41a)陶瓷層表 面以雷射方式形成有六角形凹槽（411)，再配合第四B圖 所示，各凹槽（411)的槽底較上述v形斜槽（322)更為平坦， 因此兩凹槽（41 1)之間的間壁厚度由外至内的厚度差異較 小°是以’此一蜂巢式轉印輪具長時間與刮刀具接觸其 各凹槽（411)的開口（412)改變不大，可延長使用期限。 此外’上述刮刀控墨式彩色印刷機組仍有長時間面臨 4 無法簡化轉印輪且的βι_ 八的缺點，即該刮刀控墨式彩色印刷機組 必須預備不同解柄·唐& @ Μ α m ^ 7 的轉印輪具，以因應待印刷物所需之 印刷圖案品質要求。靖免ω哲丄Λ γ 味參閱第九Α至C圖，以網點印刷作 業來說，會依據待印刷凸版所要求的網點圖案 (0a)(5Qb)(50c)的解析度高低，由大至小分別採用線數網 目由低至高的轉印輪具（41a)(41b)(41c卜當待印刷凸版所 要求的網點印刷的最小網點圖案（5〇c)如第九c圖所示， 仁卻採用如第九A或B圖所示之轉印輪具的圖案層 (41a)(41b)進行印刷，將會因各轉印輪具單一凹槽（411)的 開口（412)面積大於待印刷物所要求的網點印刷的最小圖案 尺寸（50c}，而無法提供待印刷物所要求的網點印刷解析 度。反之，若採用第九B或c圖轉印輪具的圖案層（41b)(41 c) 來印刷如第九A圖的最大網點圖案，則因各轉印輪具單一 凹槽（411)的開口（41 2)面積小於待印刷物所要求的網點印 刷的最小圖案尺寸（50a) ’而無法提供足夠的墨料予待印刷 物’造成待印刷物顏色不飽和或印刷塗料厚度不足。 由此可知’不論是凸版印刷或凹版印刷機組均必須依 據待印刷物印刷要.求採用隨時更換合適的轉印輪具，甚至 包3目别將轉印輪具應用在TFT顯示面板印刷配向膜的靡、 用，作業上相當繁雜。 【新型内容】 有鑑於上述說明既有轉印輪具缺點，本創作主要目的 係k供一種具if}含墨量及尚轉印率轉印輪具，即相較同線 數網目的蜂巢式轉印輪具具有更高的含墨量，而且轉印率 更向。 欲達上述目的所使用的主要技術手段係令該轉印輪具 包含有： 一本體，其中心軸穿設有一轉軸；及 圖案層，係均勻設在該本體外表面上，其包含有複 數道相同形狀的灣流狀溝壁，且任兩相鄰的灣流狀溝壁之 間構成一灣流槽道，又各灣流槽道斷面係' 呈_ u字形； 由上述本創作結構可知，各灣流槽道係環設於該轉印 輪具外表面上，因此各灣流槽道係為一連續開口，而非如 蜂巢狀轉印輪具的蜂巢凹部為獨立*連通的開σ，因此其 吸納墨後與待印刷物接觸後，能有效地轉印至待印刷物 提升整體墨料的轉印率；再者，由於各灣流槽道斷面 υ字形，各灣流狀溝壁的壁厚均句，若應用應刮刀供 墨式的印刷機具上，長時間使用後其開口面積變化不大， 能確保其印刷的解析度，提高使用壽命。 【實施方式】 月，閱第一圖至第四Α ®所示，係為本創作轉印輪且 (1。)-較佳實施例的外觀圖，其包含有： 卩ι 本體（11)，其中心轴穿設有一轉轴（111);於本實施 ㈣本體⑴）係為—鐵圓柱；及 人圖案層（20) ’係均勻設在該本體（11)外表面上，其 2有複數道相同形狀的灣流狀溝壁（21)，且任兩相鄰的 狀溝壁（21)之間構成—灣流槽道（22)，又各灣流槽道 係呈 u予形；於本實施例該圖案層（2〇)係先於 M378835 該鐵圓柱表面上形成厚度均勻的陶瓷層，配合精密雷射儀 器，控制電射光束以灣流路徑移動進而雕刻於陶瓷層上雕 刻出複數道平行的灣流槽道（22)。 曰 請配合參閱第四B圖及第五圖所示，係以—實際中型 轉印輪具（係以每英吋（inch)有392線數定義之）說明其含墨 量及轉印率，由於該中型轉印輪具的各灣流槽道係由複數 道連續波浪單元（222)構成，故以其中—波浪單元（222)說V. New description: [New technical field] This creation is about a transfer wheel for printing, especially a transfer wheel with high ink content and high transfer rate. [Prior Art] Please refer to the sixth figure, which is a structure diagram of a doctor blade ink control color printing unit, wherein the blade ink control color printing unit (30) comprises: an ink tank (31)' for Storing printing ink therein; a transfer wheel (32) is disposed corresponding to the position of the ink tank (3彳) so that the surface thereof can contaminate the printing ink in the ink tank (31), and the surface Forming a pattern layer (321) thereon, and absorbing the printing ink therein; a knife (33) is disposed at an appropriate position outside the transfer wheel (32), so that the blade (33) contacts the transfer wheel a surface of (32); a plate wheel (34) having a relief (341) formed on its surface and in contact with the transfer wheel (32); a pressure wheel (35) for setting the wheel A suitable position on the outer side of (34) is in contact with the plate wheel (34) to provide a contact force between the plate wheel (34) and the transfer wheel (32), and the printed matter (60) is attached to the plate wheel. Between the (34) and the pressure wheel (35). When the color printing unit (30) rotates, the surface of the transfer wheel (32) is formed with a pattern layer (321). When the rotation starts, the pattern layer (321) passes through the ink tank (31). The ink is absorbed therein, and the pattern layer is in contact with the relief (341) of the plate wheel (34), and the ink of the pattern layer is smoothly transferred 3 M378835 to the plate wheel (34) and the pressure wheel (35). On the object to be printed (6 〇) to complete the transfer. Since the transfer wheel (32) is disposed on the side to the knife (33), the blade (33) will remove excess ink from the pattern layer (32) when the transfer wheel (32) is rotated, which is effective. The amount of ink contained in the transfer wheel (32) is controlled to ensure uniformity of the ink on the pattern to be printed (60). Although the scraper (33) can control the ink content of the transfer wheel (32), it will be contacted by the pattern layer (321) of the transfer wheel (32) which is rotated to the high speed for a long time. Wear each other. Referring to the seventh figure, it is a diagonal _ straight stripe pattern layer (321), that is, the pattern layer (321) of the transfer wheel (32) is formed with a thread, please refer to the eighth figure. Shown as a longitudinal cross-sectional view of the oblique stripe pattern layer (321), the oblique stripe pattern layer (321) is engraved by a ceramic layer on the transfer wheel with a plurality of V-shaped chutes (322) Therefore, the thickness of the groove wall (324) of any two adjacent V-shaped chutes (322) is gradually increased from the outside to the inside. In this way, when the pattern layer (321) is in frictional contact with the knife (33) for a long time, the top of the groove wall (324) is gradually worn inwardly, so that the V-shaped chute originally used for absorbing the ink therein is 322) The capacity is reduced, and the opening (323) of the v-shaped chute (322) becomes large, and the precise printing function cannot be provided. Therefore, there is currently a honeycomb type transfer wheel which has been proposed. Please refer to FIG. 9A, that is, the pattern layer (41a) of the transfer wheel has a hexagonal groove formed by laser on the surface of the ceramic layer. (411), in combination with the fourth B, the groove bottom of each groove (411) is flatter than the v-shaped chute (322), so the thickness of the partition between the two grooves (41 1) is The difference in thickness from the outside to the inside is small. It is that the opening (412) of the honeycomb transfer roller has a small change in contact with the respective cutters (411) for a long time, and the service life can be extended. In addition, the above-mentioned doctor blade ink-control color printing unit still faces the shortcoming of the 4ι_8 which cannot simplify the transfer wheel for a long time, that is, the blade-controlled ink-printing unit must prepare different handles. Don & @ Μ α m ^ 7 transfer wheel to meet the quality requirements of the printed pattern required for the print. Jing ω 哲 丄Λ γ 味 According to the ninth to C map, in the dot printing operation, according to the resolution of the dot pattern (0a) (5Qb) (50c) required for the letterpress to be printed, from the big to the high Small to use the number of lines from low to high transfer wheel (41a) (41b) (41c as the minimum dot pattern (5〇c) printed on the dot required to print the letterpress, as shown in Figure IX, However, printing is performed using the pattern layer (41a) (41b) of the transfer wheel as shown in FIG. 9 or B, which will be larger than the area of the opening (412) of the single groove (411) of each transfer wheel. The minimum pattern size (50c} required for the dot printing of the printed matter, and the dot print resolution required for the printed matter cannot be provided. Conversely, if the pattern layer (41b) of the transfer wheel of the ninth B or c is used (41 c) To print the maximum dot pattern as shown in FIG. 9A, the opening (41 2) of the single groove (411) of each transfer wheel has an area smaller than the minimum pattern size (50a) of the dot printing required for the object to be printed. It is not possible to provide enough ink to be printed to 'cause the color of the print to be unsaturated or the thickness of the printed paint to be insufficient. It can be seen that 'whether the letterpress printing or gravure printing unit must be printed according to the material to be printed, it is necessary to replace the appropriate transfer wheel at any time, and even apply the transfer wheel to the TFT display panel to print the alignment film.靡 用 用 作业 作业 作业 作业 作业 作业 作业 作业 作业 作业 作业 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 有 有 有 有 有 【 有 有 有 有 有 有 有Compared with the same number of nets, the honeycomb transfer wheel has a higher ink content and a higher transfer rate.

Please refer to the fourth and fourth drawings at the same time. Compared with the transfer wheel with the same resolution, the medium-sized transfer wheel of this creation is compared with the honeycomb transfer wheel (4 0 arranged in 6 inches). The ink content of line 0) is shown in the following table: Number of meshes (line) Depth ("m) Ink content (BCM/in2, Gulf flow type 392 22 8.0 Honeycomb type 400 (60°) 19-22 4.8-5.1 As can be seen from the above table, the ink transfer amount of the same resolution and depth is 1 57 times that of the honeycomb type, and the honeycomb type with the same resolution but the smaller depth is 1_67 times. It is equivalent to the ink content of the 260-line honeycomb type transfer wheel. Therefore, the original type of transfer wheel with the ink volume of the creation is significantly higher than the same resolution, and the number of lines is less. The lower the resolution, the original embodiment can replace the 260 to 400 line honeycomb transfer for absorbent substrates or full-coated printing (such as corrugated printing, glazing or gluing). Wheels. Therefore, this creation can really replace the honeycomb transfer transfer tools of several different resolutions with 7 M378835, which helps to reduce replacement. The operation of the large-scale Gulf Stream is 266x266 mesh, in which each bay channel is composed of a plurality of continuous wave units. The length of the wave unit is 95.26/ym and the width of the weft is 86.53/ym. The channel width is 61.72/m, the groove wall thickness is 33.54//m, the channel depth is 25//m, and the ink content is 10 BCM/in2. The small-sized Gulf flow resolution is 460x460 mesh, in which each bay The flow channel _ is composed of a plurality of continuous wave units having a warp length of 56.22/ym and a weft width of 57.63/m, and a channel width of 38.98/ym and a groove wall thickness of 17 27 ;wm and the channel depth is 15/ym, and the ink content is 4.5 BCM/in2. Furthermore, the creation system makes each bay channel (22) ring on the outer surface of the transfer wheel' The bay channel (22) is a continuous opening, and the honeycomb recess, such as the honeycomb-shaped transfer wheel, is an independent non-connecting opening, so that it can be effectively transferred to the object after being sucked and inked. On the printed matter, Lu helps to improve the transfer rate of the overall ink; in addition, since each bay channel has a U-shaped cross section, The wall thickness of each bay flow ditch wall is uniform. If the application is to be applied to the knife-printing type printing machine, the opening area of the bay is not changed much after long-term use, which can ensure the resolution of printing and improve the service life.
