Unwind station7.1 Function descriptionThe objective of the unwind station is to accommodate paper reels and to feed the machine with paper at a preset tension. The paper web tension is kept constant by a system of dancer rollers and a hydraulically controlled brake system. The dancer roller system is accommodated in the print tower. A hydraulically operated brake caliper alters the position of the dancer rollers to regulate the web tension. The length of paper web in the dancer roller system also acts as a paper buffer in the event of the machine being stopped abruptly. The paper reels are held clear of the floor. The lift is effective using a hydraulic hand pump. The paper reels used are wound on cardboard cores. Two clamp heads support the reel. The diameter of the clamp heads is matched to the diameter of the paper reel cores. In order t compensate for the changing delivery angle of the web, a web deflector is arranged behind the dancer roller system in the print tower.7.2Notes on safety1. Risk of crushing!The new paper reels weigh up to 1,000 kg!2. Warning-risk of injury!Even spent reels can weigh up to 20 kg!All personnel authorized to change reels must wear safety shoes!3. When changing reels and drawing the web in by hand,the machine must be stationary and prevented from beinginadvertently switched back on!Press one of the red emergency stop buttons!7.3Residual risks1. Exercise extreme caution! Sharp edges! The edges of the paper web can inflict cuts! Keep well clear of the paperweb! Protect bare parts of the body with protective clothing!2. Exercise extreme caution! Risk of crushing injury! The paper guide rollers can inflict serious injury! Fingerscaught between paper web and guide rollers can be crushed! Never touch the paper web near the guide rollers whilst the machine is running.3. Exercise extreme caution! Risk of injury through crushing and impact. New paper reels should be prepared wellclear of the unwind station! Only splicing should be carried out in the unwind station! Unused and partially used paper reels, remove from the machine, should be prepared for storage well clear of the unwind station.4. Exercise extreme caution! Sharp knives! For paper cutting, only knives with automatically retracting blades mustbe used!5. Exercise extreme caution! Risk of crushing injury! As the space between paper reel and the floor is less than500mm, there is a risk of being crushed!6. Exercise extreme caution! Risk of crushing injury! When running the paper reel in, there is a risk of being crushedbetween the reel and the supports where the gap is less than 500mm!7. Exercise extreme caution! Risk of crushing injury! When loading or unloading paper reels, keep every part of thebody well clear of the chucks and the paper reel!8. Exercise extreme caution! Risk of crushing injury! When lowering the paper reel, always keep every part of thebody clear of the space between the paper reel and the floor! Always wear safety clothing (e.g. protective footwear)!9. Exercise extreme caution! Risk of crushing injury! The dancer roller zone may only be entered when the dancerroller is fully lowered!7.4Preparing and Feeding in the reel1. Fig.1: release the clamping (3) on the R-sideand L-side from machine2. Draw the clamping heads (1) apart to theirextreme limit with the screws (2)3.

Fig.1: Press the clamping heads into the reel core upto the stop, using the screws (2)7. Retighten the clamping lever (3)8. Tighten the clamping heads with the compressedair driver (accessory)Ensure that the clamping heads are not under pressure when tightened!9. Re-apply the disk brake.7.5Adjusting the diverting roller withan unevenly wound paper reel1.Unevenly wound paper reel causes=irregular web tensionResult: creasing and migration of the web from the machine centre 2. Fig.2: Adjust the diverting roller with the star-shaped knob (1)7.6 Compensating for paper curl1. Fig.3: Problems can arise due to curling of the paper,in particular downstream of the cross-cutter, causingproduction faults.2. In order to compensate for this curvature, the de-curlingbar is swung into the paper web.3. Fig.4: Release the clamping lever (1)4. Set the decurling bar into position with the lever (2),until those are appropriate for paper web behind the crosscutter straight on the transport tape.5. Lock the setting by tightening the clamping lever (1).Note: With reducing role diameters must the decurlingbar be readjusted7.7 Changing paper reels1. Fig.5: lower the support arms by opening the valve (1).2. Remove the old paper reel.3. Load the new reel as described at the beginning of this Chapter.4. Tear off both ends of the paper web at right angles.5. Connect the two ends with double-sided adhesive tape.6. Tighten the paper web up to the print tower by rotating the paper reel7. Apply the disk brake8. Allow the paper web to run slowly through the machine until the splices reach the collecting station. From this point onwards, the machine can be run at normal speed.8 Inking units8.1 Fluids (ink and cleaners) and accessories 8.1.1 General notesIf quality print results are to be obtained and premature wear avoided to the rubber rollers supplied and, when fitted, to the ceramic and chrome screen rollers, it is essential that the proper fluids and accessories as specified in the following chapters be used.It is essential that you contact your ink supplier well in advance in order to obtain advice on the selection and use of suitable fluids and accessories.Please make sure that you are in possession of the technical data sheets and notes on their application. Fluids include-Special inks for rubber ruling work, water dilutable -De-foaming agents-Cleaning agents, other thinnersAccessories include -Cleaning cloths-Containers for pouring inks8.1.2 Notes on the use of fluids (warning)Only use inks, cleaning media and other fluids which you have discussed and agreed with your ink supplier. The fluids must be demonstrably suitable for flexo print ruling.Other materials could result in unsatisfactory ruling results and / or damage to the rollers.Across the world, the widest variety of rubber is used. Every type of rubber will age with time; that also applies of course for the rubber rollers supplied. When in use, the surface of the roller changes within the first 4-6 months; it hardens a little, becomes smoother and less sensitive to the action of certain chemicals. For this reason, it cannot simply be assumed that new inks and other accessories that have been introduced on ‘old’ rollers can also be used on new ones.8.1.3 Fluids to be avoidedInks, water, de-foaming agents and other liquids-and most especially cleaners and thinners-must be free of the following chemical substances as their presence could lead to roller damage.a.esters, ketones, aromatic hydro carbonates and aliphatic hydro carbonates (e.g. fuels, grease, white spirit, aromatic solvents,acetone, acetic acid). Constituents in these liquids could cause welling of the rubber rollers. In addition, silicone and grease often prevent clean ink transfer.b.Chlorides. They can be contained both in tap water and in distilled water as well as in inks, in strong concentrations (﹥﹥ppm). Chlorides typically cause crevice corrosion, particularly on chromated anilox rollers.c.The water must not contain any oily substances and solid particles and must be more or less free of chlorine (in the lowerppm range).8.1.4 Types of inkLiquid concentrates are to be preferred as they are easier to handle. It is unlikely that problems will arise with these types of ink.Ink powders have the considerable disadvantage that they must be handled exactly in accordance with the manufacturer’s instructions. Even then, powder inks tend to form crystals; the ink unit and the rollers must be cleaned very often in order to avoid their being damaged. In our opinion, this disadvantage is not outweighed by the price advantage, when compared to liquid concentrates.Alcohol based inks, or inks mixed with alcohol with a flash point of less than 63o C, constitute a fire risk. It is crucial that local regulations and the manufacturer’s instructions in particular be followed faithfully. Warning: alcohol concentration above 10% can attack the plastic material in the inking system.8.1.5 Cleaning clothCloths must be lint-free, absorbent, tear resistant and oil-free. Other types of cloth will cause contamination.8.1.6 Recommendations on fluids and accessoriesInksSupplier: Jaenecke + Schneemann Druckfarben GmbHP.O.

If transport slings are used, care must be taken to ensure that the rollers are not marked by indentations; severe indentations will not recover.8.3.2 Contact with rubber surfaceOnly permit suitably tolerant fluids to come into contact with the rubber surface.Avoid touching the surfaces with your bare hands; finger prints can leave grease marks which will reduce the quality of ink。

当滑架又向前运动时，棘钩又钩住下一个工件向前运动，从而实现工件的步进传送。
插板作带停歇的往复运动，可使工件保持一定的时间间隔卸落到轨道上。

凸轮机构：其结构简单，易于设计与制造，能使从动件获得较为复杂的运动规律。 因为从动件的运动规律取决于凸轮轮廓曲线，所以在应用时只要根据从动件的运动 规律来设计凸轮的轮廓曲线就可以了。凸轮机构广泛应用于各种自动机械、仪器和 操控装置。凸轮机构之所以得到如此广泛的应用，主要是由于凸轮机构可以实现各 种复杂的运动要求，而且结构简单、紧凑。如图 4－所示的凸轮机构，凸轮以等角 速度回转，它的轮廓驱使从动件，可使推杆实现任意的运动规律，但行程较小。
缓和冲击， 吸收振动； （3） 过载时带与带轮间会出现打滑， 打滑虽然使传动失效， 但可防止损坏其他零件； （4）机构简单、成本低廉。 带传动的缺点： （1）传动的外廓尺寸较大； （2）需要张紧装置； （3）由于带 的滑动，不能保证固定不变的传动比；(4)带的寿命较短； （5）传动效率较低。 通常，带传动适用于中小功率的传动。目前 V 带传动应用最广，一般带速为 V=5≈25m/s，传动比 i≦7，传动效率 0.9 至 0.95.
摘要 我们小组设计的是包裹机包装作业过程中的块状物体推送机，其工作时要有固定的推 送行程和工作速度。我们所设计的结构是固定凸轮-连杆机构，由电动机驱动，完全由 机械结构控制实现工作要求，其工作状态稳定，效率高。本书对其设计过程做具体说 明，先对块状物体推送机的工作过程进行解析、研究，对设计要求做好全面分析，明 确设计方向；然后提出几组设计方案，对其进行分析比较，再提出总的设计方案；确 定方案后进行具体的设计，以使推送机的运动过程达到设计要求，主要包括各个构件 的尺寸大小和质量的确定，最后还要通过速度、加速度、各个构件的受力情况、压力 角等进行分析，进一步优化设计，达到减小功耗，稳定工作状态的目的。设计工作结 束后进行总结，将设计过程中遇到的问题进行总结，对设计作品做出评价。 目录 一、 课程设计任务书 设计题目 工作原理及工艺动作过程 相关数据及设计要求 设计任务 设计方案提示 二、 摘要 三、 目录 四、 课程设计题目简介 五、运动循环图 六、执行机构的选择和评价 七、机械传动系统设计计算 八、机械运动方案简图的绘制 九、机械运动系统机构的计算 十、机构运动分析

因此，曲柄连杆机构是发动机中主要的受力部件，其工作可靠性就决定了发动机工作的可靠性。
随着发动机强化指标的不断提高，机构的工作条件更加复杂。
在多种周期性变化载荷的作用下，如何在设计过程中保证机构具有足够的疲劳强度和刚度及良好的动静态力学特性成为曲柄连杆机构设计的关键性问题。
通过设计，确定发动机曲柄连杆机构的总体结构和零部件结构，包括必要的结构尺寸确定、运动学和动力学分析、材料的选取等，以满足实际生产的需要。
在传统的设计模式中，为了满足设计的需要须进行大量的数值计算，同时为了满足产品的使用性能，须进行强度、刚度、稳定性及可靠性等方面的设计和校核计算，同时要满足校核计算，还需要对曲柄连杆机构进行动力学分析。

在曲柄摇杆机构中，当极位夹角θ=0°时，曲柄摇杆机构无急回特性，无急回特性曲柄摇杆机构可根据行程速比系数，摆动角度，进行尺寸设计。
首先推导出无急回特性曲柄摇杆机构存在的条件，并依据所推导出的无急回特性曲柄摇杆机构存在的杆长条件，结合曲柄摇杆机构处于极限位置的杆长三角函数关系，推导出无急回特性曲柄摇杆机构的设计方程，由设计方程求解出杆长的设计公式，然后可根据结构要求预先选定曲柄的杆长，并借助杆长的设计公式可直接计算出其余各杆的长度。
1.2 无急回特性曲柄摇杆机构存在条件的推导当极位夹角θ=0°，即行程速度比系数K=1时，曲柄摇杆机构无急性回特性。
如图1所示，曲柄摇杆机构ABCD，曲杆AB为主动件，C1和C2点为摇杆CD所处的2个极限位置点，令 AB=a,BC=b,CD=c,AD=d。
由三角形AC 1D和AC2D得c2=（a+b）2+d2-2（a+b）dcosα2（1）c2=（b-a）2+d2-2（b-a）dcosα1（2）如图1，若极位夹角θ=0°，则必有ɑ1=ɑ2=ɑ，即A、B1、，C1、B2、C2各点共线，那么将（1）式减（2）式可得cosα=b/d (3)将(3)式代入(1)式或(2)式可得a2+d2=c2+b2 (4)因曲柄摇杆机构曲柄必为最短杆 ,所以要使(4)式成立，则必有d>c，d>b，d>a，即d为最长杆.由图1所示假设AB是曲柄，AD是机架。

轴类零件是旋转体零件，其长度大于直径，一般由同心轴的外圆柱面、圆锥面、内孔和螺纹及相应的端面所组成。
导杆主要用来支承传动零部件，传递扭矩和承受载荷，故其广泛应用于各类机械产品中。
二、导杆的技术要求36HRC；孔Φ20要满足以中心轴线E （1）零件的材料为38Cr，其表面要求热处理30~为基准的对称度要求为0.1mm，垂直度要求为0.05mm；轴右端Φ18要满足以中心轴线E为基准的同轴度要求为Φ0.03mm；轴内螺纹孔4xM6-6H满足深度为8，以中心轴线D为基准的位置度要求满足Φ0.3mm；轴大端加工出C3倒角，轴小端加工出C2倒角。
Φ-mm的圆柱面对公共轴线的同轴度为Φ0.025mm；4⨯M6-6H对公共轴线（2）180025.0的位置度为Φ0.3mm；（3）该零件轴段的安排呈阶梯型，其加工精度要求较高，要有较高的形位公差，表面粗糙度最高达到了0.4µm，零件的中心轴是设计基准和工艺基准。
（4）通过对该零件图的绘制，知原图样的视图正确，尺寸、公差及技术要求齐全。
（5）该零件属于轴类零件，它的所有表面均需要切削加工，各个表面的加工精度和表面粗糙度都不难获得。
该零件除工作表面外，其余表面加工精度较低，通过车削，钻削等的一次加工就可以达到加工要求，主要工作表面虽然加工精度相对较高，但也在正常的生产条件下，采用较经济的方法保质保量的加工出来，由此可见，该零件的工艺性较好。
三、零件的工艺分析（1）零件的毛坯材料38Cr是典型的轴用材料，综合机械性能良好。
该材料是优质合金钢，经调制处理之后具有良好的力学性能和切削加工性能。
经淬火加高温回火后具有良好的综合力学性能，具有较高的强度、较好的韧性和塑性。
（2）根据表面粗糙度要求和生产类型，表面加工分为粗加工和精加工。
加工时应把精加工和粗加工分开，这样经多次加工以后逐渐减少了零件的变形误差。
（3）此零件的毛坯为模锻件，外形不需要加工。
（4）该轴的加工以车削为主，车削时应保证外圆的同轴度。
（5）在精车前安排了热处理工艺，以提高轴的疲劳强度和保证零件的内应力减少，稳定尺寸、减少零件变形，并能保证工件变形之后能在半精车时纠正。
（6）同一轴心线上各轴、孔的同轴度误差会导致轴承装置时歪斜，影响导杆的同轴度和使用寿命。
所以在车削磨削过程中，要保证其同轴度。
第二节确定毛坯、绘制毛坯图一、零件分析该零件材料为38Cr，考虑到车床在加工过程中要经常正反向旋转，该零件在加工过程中要承受载荷作用，因此选用锻件，以使金属纤维尽量不被切断，保证零件工作可靠。
假设为批量生产，零件的轮廓尺寸不大，故采用模锻成形来制造毛坯。
模锻成形后切边，进行调质，调质硬度合适，并进行酸洗，喷丸处理。
喷丸可以提高表面硬度，增加耐磨性，消除毛坯因脱碳而对机械加工带来的不利影响。
二、设计毛坯图导杆毛坯图见附图。
三、确定毛坯的毛坯尺寸、尺寸公差和机械加工余量参照课程设计指导教程第二章第二节确定模锻毛坯尺寸的公差和机械加工余量，查表2-6、表2-9首先确定如下各项因素：（1）公差等级由于导杆的用途和技术要求，确定该零件的公差等级为普通级。
（2）锻件质量Mt假设零件成品质量为1.5kg，估算锻件毛坯质量Mt=2.5kg。
（3）锻件形状复杂系数S对导杆零件图进行分析计算，可大致确定锻件外扩的长度、宽度、高度，则可计算出该导杆锻件的形状复杂系数S=Mt/Mn。
该锻件为长轴形，其最大直径为56mm，长255mm，估计该零件的形状复杂系数属S2级，即该锻件的复杂程度为一般。
（4）锻件材质系数由于该导杆材料为38Cr，38Cr表示含碳量为0.38%的合金结构钢，其中Cr平均含量<1.5%，故该锻件的材质系数为M1级。
（5）零件表面粗糙度由零件图可知，除孔Φ20、轴中部为0.8um，轴左端Φ40 、Ra=0.4um以外，其余加工表面Ra>=1.6um。
（6）确定机械加工余量根据锻件质量，零件表面粗糙度、形状复杂系数查表2-9，由此查得单边余量在厚度方向为1.7~2.2mm，水平方向为1.7~2.2mm,各轴向尺寸的单面余量为1.7~2.2mm，孔的单面加工余量查表2-10为2.0mm。
根据轴的尺寸长度与零件直径，查工艺手册得端面的加工余量为2mm。
第三节拟定导杆工艺路线一、定位基准的选择正确的选择定位基准是设计工艺过程中的一项重要的内容，也是保证加工精度的关键。
定位基准有精基准和粗基准之分，通常先确定精基准，然后确定粗基准。
（1）精基准的选择选择轴左端面端面500025.0Φ-和中间端面180025.0Φ-为精基准。
零件上的很多表面都可以以两端面作为基准进行加工。
可避免基准转化误差，也遵循基准统一原则。
两端的中心轴线是设计基准。
选用中心轴线为定为基准，可保证表面最后的加工位置精度，实现了设计基准和工艺基准的重合。
由于两轴面的精加工工序要求余量小且均匀，可利用其自身作为基准。
（2）粗基准的选择粗基准的选择应能保证加工面与非加工面之间的位置精度，合理分配各加工面的余量，为后续工序提供精基准。
所以为了便于定位、装夹和加工，可选轴的外圆表面为定为基准，或用外圆表面和顶尖孔共同作为定为基准。
