【摘要】：隨著我國(guó)的石材需求量和供應(yīng)量日益增多，人們對(duì)石材的數(shù)量和質(zhì)量要求不斷提高，而在石材表面涂覆這方面，多數(shù)企業(yè)仍停留在人工涂覆的加工方式，不僅費(fèi)時(shí)費(fèi)力而且無(wú)法保證涂覆的質(zhì)量。此種方法無(wú)法使石材表面各部分的涂覆厚度保持均勻，石材表面缺陷中的水汽將存于涂料之下，易受溫度等影響破壞涂覆表面，需定期維護(hù)。因此本課題實(shí)現(xiàn)了石材在真空狀態(tài)下自動(dòng)涂覆，并使涂覆的高分子薄膜材料在壓差作用下浸入石材本體空隙和缺陷中，提高石材表面涂覆質(zhì)量和生產(chǎn)效率。 根據(jù)石材真空涂覆裝置的設(shè)計(jì)要求，對(duì)設(shè)備的各個(gè)功能機(jī)構(gòu)提出多種設(shè)計(jì)方案，并進(jìn)行分析和選擇，對(duì)各種設(shè)計(jì)方案的優(yōu)缺點(diǎn)進(jìn)行比較，按照一定的選用標(biāo)準(zhǔn)，綜合考慮各種設(shè)計(jì)方案的特點(diǎn)，選擇最佳方案。 根據(jù)選定的各部件的最優(yōu)方案，，對(duì)真空涂覆裝置進(jìn)行三維建模。使用有限元分析軟件進(jìn)行靜力學(xué)分析，模態(tài)分析和瞬態(tài)分析得出了最大回氣速率。為消除真空涂覆裝置的結(jié)構(gòu)缺陷提供理論依據(jù)并進(jìn)行改進(jìn)設(shè)計(jì)。 根據(jù)對(duì)具體的工作條件和方式設(shè)計(jì)真空室結(jié)構(gòu)并選用合適的密封方案，包括真空槽，真空泵，吸塵器和真空計(jì)的選型，電極的引入等。通過(guò)對(duì)不同開(kāi)門方式的比較選用合理的開(kāi)門方式和氣缸。
[Abstract]:With the increasing demand and supply of stone in our country, the quantity and quality of stone are increasing. However, in the aspect of stone surface coating, most enterprises still stay in the processing mode of manual coating, which is not only time-consuming and laborious, but also can not guarantee the quality of coating. This method can not make the coating thickness of each part of the stone surface uniform, the water vapor in the stone surface defects will be stored under the coating, easy to be affected by temperature to destroy the coating surface, it needs to be maintained regularly. Therefore, this paper realizes the automatic coating of stone in vacuum, and immerses the coated polymer film material into the gaps and defects of stone body under the action of pressure difference, so as to improve the coating quality and production efficiency of stone surface. According to the design requirements of stone vacuum coating device, a variety of design schemes are put forward for each functional mechanism of the equipment, and the advantages and disadvantages of each design scheme are compared. According to certain selection standards, the characteristics of various design schemes are comprehensively considered, and the best scheme is selected. According to the optimal scheme of each component, the vacuum coating device is modeled in three dimensions. The maximum return rate is obtained by static analysis, modal analysis and transient analysis with finite element analysis software. It provides a theoretical basis for eliminating the structural defects of the vacuum coating device and improves the design. According to the specific working conditions and methods, the structure of vacuum chamber is designed and the suitable sealing scheme is selected, including the selection of vacuum tank, vacuum pump, vacuum cleaner and vacuum gauge, the introduction of electrode and so on. Through the comparison of different opening modes, the reasonable opening mode and cylinder are selected.
