外文翻译--剥壳机的介绍

- 1 - 附 录 1 剥壳机的介绍 1.挤压式莲子剥壳机 挤压式莲子剥壳机最早的模型为双辊式莲子剥壳设备。设备中一辊为带有橡胶层的旋转圆柱体， 另一与之相对转动的辊上带有三角形刀刃的多个盘形圆片组成。使莲子通过两辊的中缝时，切开莲壳。然而几经实验，莲子仅被刀刃划破了部分外壳。由于在两辊之间的加工区较短，莲子不可能在其中滚上一两圈，因而使莲壳的切破率大大降低 5。浙江大学的郑传祥教授，对于前人提出的挤压式莲子剥壳机原理进行了进一步的改进，从而在此基础上设计了一种更能适应生产实际的高效莲子剥壳机。完善了挤压式的双辊技术 。利用高速刀具对莲子外壳进行切割、挤压使其脱壳， 同时增加了脱壳切割的刀具数量， 使其更适合机械该机型可以将莲子按照其颗粒大小分化生产6-7。类后进行脱壳，使莲子生产实现在机械化的道路上向前迈进了一大步。 2.摩擦式莲子剥壳机 旋转圆桶式脱壳机是比较早期的摩擦式剥壳机，其在中部旋转轴上装有盘形刀片，外桶固定在机架上，其内壁上衬有适当厚度的橡胶层。莲子进入后，随旋转轴的带动，在内壁与转轴的刀片中滚动，莲壳在橡胶层的衬垫下被转动的盘形刀片切破，然后从其夹缝中掉出 5。但是由于被切破的莲壳均牢牢的粘附在莲肉 上，为使莲壳与莲肉分离， 还得专门设计一个搓壳机。为了克服旋转圆桶式莲子脱壳机固有缺陷，在其基础上， 6JD-400 型莲子剥壳机设计成三个加工段 破壳段、搓壳段及软搓壳段。每小时每台可加工 70 kg，脱壳率平均为 75%以上， 出莲肉完好率平均 9 5% 以上，且筛分率大于 90 %，莲子损害率小于 4 % 以下，但每副刀片使用 5 6班需重磨一次3。经生产实践表明， 6JD-400 型莲子剥壳机性能稳定可靠，自动化程度高，便于操作。 在我国经济中，制造业是国家的支柱行业，占据国有经济的重要地位。随 着制造业的快速发展，机械工程技术也迎来了新的发展形势。从目前机械工程技术的发展来看，在产品研发和生产制造中，机械工程技术正在缩小与国外发达国家的差距，在某些产品领域已经达到了世界领先水平。之所以取得这样的成绩，主要原因在于机械工程教育中引入了信息化的理念，不但提- 2 - 高了机械工程的教育效果，也促进了机械工程教育的发展，所以，我们应对机械工程教育信息化发展有全面正确的认识。 1、机械工程技术的先进性特点 （ 1）灵活（ 2）高效率（ 3）能源消耗低（ 4）无污染（ 5）产品性价比较高。 2、综合考虑设计与工艺的特点 在机械工 程技术方面，设计与工艺紧密结合十分重要，在实际生产过程中，需要结合现场的工艺进行合理的设计，使设计一次性成功，这就是经常所说的并行工程。 3、全面考本文由论文联盟 http:/www.LW收集整理虑工业应用的特点 对于机械工程技术来说，最终的目的就是提高制造行业的经济效益和社会效益。这就要求在设计之前详细了解市场，针对工业应用情况进行设计、研发、生产、销售等等，使该技术能够达到理想中的效果，这样的机械工程技术才算是成功的。 考虑到机械工程的特点，在机械工程教育开展的过程中，引入信息化手段是十分必 要的。从目前机械工程教育信息化发展现状来看，主要表现为以下几个方面： 1、机械工程教育信息化手段已经得到了充分的运用 出于提高机械工程教育质量的目的，在机械工程教育开展过程中，及时的引入了教育信息化的手段，主要包括 CAD教学、网络化教学等，通过教育信息化手段的运用，机械工程引进了国外技术的先进理念，形成了对国外先进技术的消化吸收，保证了机械工程能够持续快速的发展。从目前机械工程教育的开展来看，信息化手段的运用范围越来越广，已经成为了机械工程教育的主要手段之一，为机械工程教育的发展提供了有力的支持。随着教育信息化手段的不断发展和提高，相信在未来机械工程教育信息化手段的应用范围更广，应用效果更加突出。 2、机械工程教育信息化采用了网络化发展的模式 计算机网络的发展，为机械工程教育提供了强有力的支持，不但提升了机械工程教育信息化发展的质量，还提高了机械工程教育的整体效果，改变了传统教育模式的束缚，为机械工程教育的发展提供了新的参考。从目前机械工程教育信息化的发展来看，网络化的发展模式为其带来了资源共享的便利，丰富了现有的教育内容，提高了教学实效性，为机械工程教育的发展注入了生机和活力。从这一角度来看，机械工程教育信 息化发展成为了机械工- 3 - 程技术发展的必然趋势，为了机械工程技术的提高奠定了坚实的基础，保证了机械工程技术的发展质量。 3、机械工程教育信息化改变了传统教育理念 在传统教育理念中，机械工程的教育应尊重书本内容，应以现有技术为基础进行技术研发和技术教育，对先进技术的引入缺乏必要的手段。考虑到机械工程传统教育理念的缺点，以及计算机信息化的高速发展，在机械工程教育中引入信息化手段已经成为了必然的选择，对机械工程的发展产生了重要影响。基于这一判断，机械工程教育信息化改变了传统的教育理念，开始朝着新技术引入和新技术应用的方 向发展，极大的提高了机械工程教育的实效性，满足了机械工程发展的现实需要，提高了机械工程发展的整体质量，为机械工程发展提供了新的参考。 4、机械工程教育信息化提高了教育效果和技术的先进性 通过采用教育信息化手段，机械工程的教育效果得到了持续的提高，为机械工程技术的发展提供了有力的支撑，保证了机械工程技术的发展质量。同时，教育信息化手段的采用，保证了机械工程技术的先进性，使机械工程技术能够及时的引入并借鉴国外的先进经验和成熟的技术，为我国机械工程技术的发展提供有力的支持。从目前机械工程教育的实际发展来看，机械工程教育信息化提高了教育效果和技术的先进性，为机械工程的发展提供了有力的支持。因此，从促进我国机械工程技术发展的角度出发，我们应对机械工程教育信息化手段有深入的 通过本文的分析可知，在我国机械工程技术的发展过程中，教育信息化手段起到了积极作用。教育信息化手段不但提高了机械工程教育的整体效果，还对机械工程技术的发展提供了有力的支持，满足了机械工程技术发展的要求。因此，我们要对机械工程教育信息化手段有全面正确的认识，要认真分析机械工程教育信息化发展现状，不断提高机械工程教育信息化的发展质量。 - 4 - 附 录 2 The sheller introduction 1 extrusion lotus sheller Squeeze lotus Sheller earliest models for the double roller lotus sheller equipment.
