Example 1: Rubber products

橡胶行业

从汽车制造到医疗技术:型材、管子、包层、环带和许多其他部件都是由橡胶化合物制成的。这些混合物是由经过优化的配方组成的,尤其是为了达到这个目的,尽管大多数外行人将其简单地定义为“橡胶”。From vehicle manufacturing to medical technology: Profiles, tubes, cladding, ring belts and many more components are made of rubber compounds. These mixtures are composed of optimised formulation especially for the purpose, although most laypeople would simply define them as “rubber”.


.除了基本配方外,挤出机的机械技术还负责橡胶产品的形状,尤其是最稳定的质量。虽然形状与使用的工具相符,但质量实际上取决于挤出机的“内部质量”。因此,为挤出机制造商工作的工程师始终关注挤出机技术,以便随着进一步的发展积极影响质量。As well as the basic formulation, the machine technology of the extruder is responsible for the form and in particular for the most consistent quality possible of the rubber products. While the form conforms to the tools being used, the quality effectively depends on the “inner qualities” of an extruder. The engineers working for extruder manufacturers therefore always focus on the extruder technology, in order to positively influence quality with further developments

 

Drehdurchführung an ExtruderFor clarification, a cold-feed pin-type extruder should be used for this purpose.The necessary temperature conditioning of the extruder screw is carried out using a rotating union. This temperature conditioning is state of the art and a general prerequisite for maintaining technical parameters.

However, development engineers want to do more to improve the quality and reproducibility of their production results and the concept of tempering further machine components has been adopted.

This is how a temperature conditioning process for the top and bottom rotors of the gear pump using an additional rotating union has been implemented. The gear pump, as such, already has benefits in terms of more equal output and constant dimensional accuracy, because a material feed just before the die (tool) is much more effective than simply feeding it over the extruder screw. Additionally, tempering the pump enables a better portioning of the rubber mixture and at the same time increases the mixture quality. 这就是如何使用附加旋转接头对齿轮泵顶部和底部转子进行温度调节的过程。因此,齿轮泵在输出更均匀和尺寸精度恒定方面已经有了好处,因为在模具(工具)之前的材料进料比简单地通过挤出机螺杆进料更有效。此外,对泵进行回火可以更好地分配橡胶混合物,同时提高混合物的质量。

当然,热必须应用于正在被挤压的热塑性材料,但在挤压机中有一个位置,在这个位置上,较低的温度有一个有趣的更好的效果:进料辊。While it is a matter of course that heat must be applied to the thermoplastic materials that are being extruded, there is a position in the extruder whereby cooler temperatures have an interestingly better effect: the feed roller.

更冷、更稳定的股线可以更好地喂入,并且可以更一致地喂入挤出机。Cooler, more stable strands can be fed in better and can be more consistently fed into the extruder.

通过使用更小、更紧凑的旋转接头,这一想法得以实现。结果表明,该材料的入口特性明显改善。这种技术方法甚至可以使进料滚柱上的滚针或圆柱滚子轴承冷却,进一步优化。This idea was made into reality with the use of smaller, more compact rotating unions. The results show that the entry characteristics of the material were significantly improved. This technical approach could even enable the needle or cylinder roller bearings on the feed roller to be cooled, with further potential for optimisation.

Example 2: Plastic films
塑料薄膜

Regardless of the current discussion about the “plastic planet” film, according to which our planet, by now, could be wrapped several times in plastic, packaging film will remain essential to packaging for the foreseeable future.

However, the development of increasingly thinner films is encouraged among manufacturers, in order to conserve resources, yield more from the same input of raw materials and produce more in the same amount of time.These development trends have an effect on machine technology, because bigger machines are being used and/or machine speeds are being increased. 但是,为了节约资源,在相同的原材料投入下获得更多的产量,在相同的时间内生产更多的薄膜,制造商之间鼓励发展越来越薄的薄膜,这些发展趋势对机器技术产生了影响,因为正在使用更大的机器和/或提高机器速度。

folienwickelmaschine卷膜

在薄膜制造过程中,通常在原料撕裂前,使用滚轴和拉伸器将其拉伸至物理极限。用于此过程的滚轴使用导热油或热水等传热介质加热,以暂时增加塑料中分子结构内的熵。这降低了它的稳定性,热塑性变形性被用来拉伸结构,旋转接头被用来将所需数量的传热介质转移到辊上。它们起着连接固定进料管/软管和旋转滚筒的作用。由于每小时都有大量的介质流过滚筒,因此人们希望保持或提高成品的质量。只有当“机器作为一个整体”以极高的精度运行时,才有可能做到这一点。因此,这也适用于机器部件,如旋转接头,因为工作参数-介质、压力、温度和转速-总是影响使用寿命,德布林等品牌制造商正在不断开发用于塑料机械的旋转接头,因此,有短而紧凑的设计、单流和多流设计以及不锈钢旋转接头的版本。所有产品均标配可靠、低磨损的机械密封。During film manufacturing, the raw material is very generally stretched using rollers and stretchers to its physical limit, just before it tears.The rollers used for this process are heated using heat transfer media such as thermal oil or hot water, in order to temporarily increase the entropy within the molecular structure in the plastic. This reduces its stability and the thermoplastic deformability is used to stretch the structure.Rotating unions are used to transfer the required quantity of heat transfer medium to the roller. They function as a link between the stationary feed pipes/hoses and the rotating roller.As well as the significant volume of media flowing through the rollers each hour, there is a desire for the quality of the finished product to be maintained or improved.This can only be possible if the “machine as a whole” operates with tremendous accuracy. Therefore, this also applies to the machine components such as the rotating unions, because the operating parameters - medium, pressure, temperature and rotational speed - always affect the service life.For this reason, brand manufacturers such as DEUBLIN are continuously further developing the rotating unions used in plastic machines.Consequently, there are versions with a short, compact design, monoflow and multiflow designs and rotating unions made from stainless steel. All of these products are equipped with reliable and low-wear mechanical seals as standard.

Example 3: Calenders or coating and laminating
砑光机或涂层和层压

压延机和用于涂层和层压的机器经常在非常高的温度下使用,需要特殊的热介质旋转接头。经验表明,以前和现在,在某种程度上,旋转接头是通过适配器和螺钉连接到供应线的。这些连接复杂、耗时,在安装和维护过程中往往需要大量的努力。此外,即使由经验丰富的合格人员安装,它们仍然极易发生故障;由于轴承或滑环的早期损坏,可能在以后的某个时间点发生损坏,从而缩短旋转接头的使用寿命。Calenders and machines for coating and laminating are frequently used at very high temperatures and require special hot media rotating unions.Experience has shown that previously and, to some extent, nowadays, rotating unions were connected to the supply line using adaptors and screws. These connections are complex, time consuming and often require a great deal of exertion during installation and maintenance. Moreover, they remain extremely fault-prone, even if they are installed by experienced and qualified personnel; damage may occur at a later point as a result of earlier damage to bearings or slip rings, resulting in a reduced life span of the rotating union.


在适应过程中,流量区域被压缩,导致加热器输出减少和压力损失增加。随着SAE法兰的开发和随后的使用,这个问题已经成为过去,因为连接点现在有了一个新的简单设计。四个螺丝、一个O形圈和一个法兰稳稳地接管到供应线和旋转接头的连接,一个内六角键足以作为完成安装的工具。这种设计使安装和维护成本大大降低,因为供应线可以在最短的时间内无张力连接。也可以在不需要大量工具的情况下进行拆卸,从而减少机器停机时间,并为操作人员带来明确的成本优势。由于压力弹簧,例如,位于介质之外。这就是滚柱或压延机如何通过旋转接头不断向传热介质提供正确的体积流量的方法。压力损失和热量输出不再发生。根据使用的系列,这种热介质旋转接头显示出稳定的轴承设计和以膜形式的二次密封,因此在密封点处没有相对运动。此外,为了提高机器安全性,可订购带有外壳和转子锁环以及附加卡环的型号,作为“紧急安全锁销”。It has also been demonstrated that during adaption processes, the flow area is constricted, leading to a reduced heater output and an increased loss of pressure.drehdurchführung mit flanschWith the development and consequent use of an SAE flange, this problem is a thing of the past, as the connection points now have a new and simple design. Four screws, one O-ring and a flange steady take over the connection to the supply line and rotating union and an inner hexagonal key suffices as a tool for complete installation.This design enables the installation and maintenance costs to be significantly reduced, as the supply lines can be connected free of tension in the shortest amount of time possible. Disassembly is also possible without the need for lots of tools, leading to less machine downtime and unequivocal cost advantages for the operator.The “tense installation” of the rotating unions is constructively avoided and the life span of the unions increases in the same way as the energy efficiency, because the pressure springs, for example, are situated outside of the medium. This is how the rollers or calender are kept constantly supplied with the correct volume flow rate to the heat transfer media by the rotating union. Loss of pressure and heat output no longer occurs.Depending on the series used, such hot media rotating unions display a stable bearing design and a secondary seal in the form of a membrane, therefore there is no relative motion at the sealing point. Moreover, for increased machine safety, versions with housing and rotor locking rings and additional snap rings can be ordered as an “emergency safety catch”.



Conclusion结论:

因此,为机器制造商和高质量旋转接头制造商工作的工程师的专业知识导致了进一步的发展和不断发现新的潜力,从而可以实现未来的进一步目标。投资于由高品质组件和部件制成的高品质机器,在考虑到最新发展的情况下进行设计,很快就会有回报!The expertise of the engineers working for machine manufacturers and manufacturers of high-quality rotating unions consequently leads to further developments and the constant discovery of new potential, with which further goals for the future can be reached.Investment in high-quality machines made of high-quality assemblies and components, designed with the most recent developments in mind, pays off in no time
