【摘要】：近年來,我國國民經(jīng)濟發(fā)展迅速,人民生活水平有了很大的提高。市場對金屬包裝制品的需求和質量要求越來越高,為了滿足市場需求,提高我國印鐵行業(yè)的自主研發(fā)能力,國內各個印鐵企業(yè)大力發(fā)展相關技術,努力提高印鐵生產(chǎn)線的單線生產(chǎn)效率和金屬印制品的質量。烘房生產(chǎn)線作為印鐵生產(chǎn)線的重要組成部分,直接制約了全線的生產(chǎn)效率和產(chǎn)品質量,因此對于烘房相關技術的研究對于金屬包裝業(yè)的發(fā)展有著至關重要的作用。 論文首先探討了烘房的上料裝置,分析烘房上料裝置的工作原理,并提出制約烘房高速上料的影響因素。在此基礎上,分析現(xiàn)有的上料裝置的工作效率,根據(jù)實際生產(chǎn)需要,設計了新型的上料裝置,解決了高速上料易引發(fā)的撞鐵和精確定位等問題。然后探究了烘房溫度均勻性問題。在本論文中主要探討不同的烘房結構和不同的工藝參數(shù)對烘房溫度均勻性的影響。在烘房結構方面,主要是對氣流的噴嘴、分風導流片和氣流出口三個方面進行研究,分析其對溫度均勻性的影響程度。針對氣流噴嘴,考慮其直接影響入風的風量大小、送風角度、送風范圍等因素,分別分析噴嘴的數(shù)量、布局以及形狀對溫度均勻性的影響；針對分風導流片,設計一種新式的結構,有利于風量的分配,并對導流片的位置進行優(yōu)化,設計多組實驗,找到最利于風量分配的導流片位置；最后考慮氣流的循環(huán)出口形狀對溫度均勻性的影響程度。在工藝參數(shù)方面,主要考慮入風的風速和入風的溫度對均勻性的影響程度,分別設定烘房在不同的送風速度和送風溫度下,溫室溫度的變化情況,觀察各溫度分布規(guī)律隨各參數(shù)的變化情況,并根據(jù)各自規(guī)律和實際情況得到最佳的工藝參數(shù)。 本論文的設計研究都是從實際生產(chǎn)出發(fā),一方面能夠提高烘房生產(chǎn)線的工作效率和產(chǎn)品質量,同時另一方面對節(jié)約材料和資料的合理利用有著至關重要的作用,因此具有很大的實用價值。
[Abstract]:In recent years, China's national economy has developed rapidly, the people's living standards have been greatly improved. In order to meet the demand of the market and improve the independent R & D capability of China's printing iron industry, the domestic printing iron enterprises vigorously develop the relevant technology, in order to meet the needs of the market and improve the independent R & D capability of the printing iron industry. Try to improve the single-line production efficiency of printing iron production line and the quality of metal printing products. As an important part of the printing iron production line, the oven production line directly restricts the production efficiency and product quality of the whole line. Therefore, the research on the relevant technology of the oven has a vital role in the development of the metal packaging industry. Firstly, the paper discusses the feeding device of the oven, analyzes the working principle of the feeding device, and puts forward the influencing factors that restrict the high-speed feeding of the oven. On this basis, the working efficiency of the existing feeding device is analyzed. According to the actual production needs, a new feeding device is designed, which solves the problems of iron collision and accurate positioning caused by high speed feeding. Then it explores the temperature uniformity of the oven. In this paper, the effects of different oven structure and different process parameters on the temperature uniformity of the oven are discussed. In the aspect of the structure of the oven, this paper mainly studies the nozzle of the air flow, the flow guide and the outlet of the air flow, and analyzes the influence of the nozzle on the temperature uniformity. Considering the factors such as air volume, air supply angle and air supply range, the influences of the number, layout and shape of the nozzle on the temperature uniformity are analyzed respectively. A new type of structure is designed, which is advantageous to the distribution of air volume, and optimizes the position of the guide vane, and designs many groups of experiments to find the location of the most favorable air volume distribution. Finally, the influence of the flow outlet shape on the temperature uniformity is considered. In terms of process parameters, considering the influence of the wind speed and the temperature of the inlet air on the uniformity, the change of greenhouse temperature in the different air supply speed and temperature is set respectively. The variation of temperature distribution with each parameter was observed, and the optimum process parameters were obtained according to their own rules and actual conditions. The design and research of this thesis are all based on actual production. On the one hand, it can improve the working efficiency and product quality of the oven production line, on the other hand, it plays an important role in saving the reasonable use of materials and materials. Therefore, it has great practical value.
