【正文】 ABSTRACT Design packaging machine loquat loquatbased packaging design, the use of environmentally friendly type of pulp through the system for agencies, according to the requirements of Loquat corresponding packaging design and to achieve its intended requirements. Loquat packaging machine system is environmentally friendly and can replace the mold to plete the suppression of different products. The body hydraulic system and plc control to work together to plete suppression. The hydraulic technology in China has been widely use, and pared to other transmission control technology, the hydraulic system with high energy density, configuration flexibility, speed range, stable, exercise performance, easy to overload protection, easy to automate Integration of electrohydraulic one. The agencies, according to loquat packaging machine according to the required load, the development of the hydraulic system diagram, has been calculated to determine the parameters of the hydraulic system. Keywords: piece design； hydraulic system； mechatronics； PLC control linking 紅河學(xué)院本科論文（設(shè)計(jì)） Ⅰ 目錄 第一章 緒論

科學(xué)技術(shù)是第一生產(chǎn)力，科技創(chuàng)新是社會(huì)進(jìn)步的源泉。各國之間的較量演變成科技的創(chuàng)新。從而讓我們國家在世界上立以不拜之地。很多有害的、難降解的材料更是數(shù)不勝數(shù)。這些有害的垃圾被埋在土里混在水里，不僅造成了土壤資源的污染讓農(nóng)作物植物生長困難，而且影響了地下水的水質(zhì)。 在這個(gè)物欲橫流的社會(huì)里，人們對健康的要求越來越高，對生存環(huán)境的要求也在逐步提高。本機(jī)構(gòu)的理論意義就是為環(huán)境創(chuàng)造一段生存的時(shí)間，為環(huán)境保護(hù)提供一個(gè)實(shí)際的建議；為中國乃至世界的紙漿行業(yè)增添一份光彩；為保護(hù)環(huán)境獻(xiàn)上一份力量；為人類的健康獻(xiàn)上一份大禮；為中國的綜合國力出一點(diǎn)力。本機(jī)構(gòu)的現(xiàn)實(shí)意義就是把紙漿類材料通過該機(jī)構(gòu)的加工轉(zhuǎn)換成低成本高環(huán)保高效益的產(chǎn)品，把枇杷包裝順利快速的壓 制成型。 國內(nèi)外發(fā)展?fàn)顩r
