张力卷筒

Treating with coils as aeolotropy, this paper brings forward a set of mathematical mode for computing internal stress distribution of coil in the process of coil coiling, in which some factors are taken into account, such as the transverse distribution of shape, crown and curl tension of the strip, the friction between the strip and the reel, the friction between strips, and etc. Because the reel shrinkage and the inner circle of the strip losing radial restrain and circumferential restrain can induce interlayer slipping and the change of the whole coil compactedness , the assumption concerned ——"virtual reel" in the process of coil uncoiling is put forward, which takes the form of slow action to express the uncoiling process and, therefore clearly simulates the variation course of internal stress distribution of coil in the process of coil uncoiling.

In the business card printing and membership card making to be represented by tension controller to control business card printing and membership card making constant tension, is the key to so overprinter accurate, tension control system is any drum business card printing and membership card making machine one of the main body, to a large extent determine the prints overprinter accuracy, tension and control institutions are primarily provided at bleeder part business card printing and membership card making-position-and-drop your material up institutions, material roll output you need to turn the material roll resistance, inertia, coiling has it own tension values, together with the business card printing and membership card making speed uponsize traction, Business card printing and membership card during various color group overprinter on the resistance of the material makes it possible to put volume, the business card printing and membership card production, letoff institution of tension control is important, the size of the tensility control should see materials of munltivariable, of the material used-narrow to decide.

在制卡和会员卡制作过程中由张力控制器来控制制卡和会员卡制作张力的恒定，是套印准确的关键所以，张力控制系统是任何卷筒制卡和会员卡制作机的一个重要机构，它在很大程度上决定印品的套印准度，张力控制机构主要设于放料部分，制卡和会员卡制作工位和放收料牵引及收卷机构、料卷输出需要阻力，料卷转动有惯性，卷料自身也存在一定的张力值，加上制卡和会员卡制作速度的拉力牵引，制卡和会员卡制作过程中各色组套印对被印材料的阻力使得放卷、制卡和会员卡制作、收卷机构的张力控制显得尤为重要，张力控制的大小应视材料的厚薄、质料宽窄来决定。

Chinese cable reel to the door wide application of the plane, with the big cable in the road so that the process is to avoid being hurt. must maintain an appropriate tension here at present, the cable reel drives used in three main ways : namely (1) the torque-motor (2) use of cage-plus motor hysteresis coupling;(3) The torque motor controller to increase frequency hysteresis couplings.

中文摘要：电缆卷筒在门机上被广泛应用，在使电缆随大车的行进过程中要避免受到伤害，必须保持一个合适的张力，这里介绍了目前门机电缆卷筒驱动装置主要采用的三种方式：即（1）采用力矩式电机；（2）采用笼型电机加磁滞式联轴器；（3）采用力矩控制器加变频电机加磁滞式联轴节。

Cable reel motor torque constant tension which has the characteristics When the load increases in the motor output shaft speed will automatically come down, volume Rao assured when cable tension unchanged. Rao nature of this excellent performance closely integrated with the Volume; Cage used motor hysteresis coupling increases in size, functionality, easy installation, the constant tension similar characteristics, we can under the conditions required output torque. They can pull the cable external circumstances, hysteresis coupling protect cables; using torque motor controller to increase frequency hysteresis couplings Surge part because of the cable reel SCR converter using a new technology operation, smoothing adjustments to the motor terminal voltage, thereby ensuring that the output torque of the motor unchanged. so that the cable can smooth the road with the truck

其中力矩电机电缆卷筒具有恒张力的特点，当负载增加时电机的输出轴转速能自动随之降低，保证电缆卷饶时张力不变，这个优越的性能与卷饶性紧密结合；采用笼型电机加磁滞式联轴器具有体积小，功能全，安装维护方便，近似恒张力等特点，既可以根据工况需要输出力矩，又可以在电缆受外力拉住的情况下，通过磁滞式联轴器保护电缆；而采用力矩控制器加变频电机加磁滞式联轴节的电缆卷筒因其调压部分采用可控硅变流新技术，可以平滑地对电机的端电压进行调节，从而保证了力矩随负载的变化而改变，使电缆能平稳的跟大车的行进。

At first, according to the mechanical vibrationtheory and detailed analysis on coiling the different stage mathematical models of coiling are set-up. The correlation equations of the models are also given. Then, the paper presents an analysis ofthe moment of inertia of coiler in hot strip mill in detail, the equation of the inertia moment and theanalysis.

Because the length of the tension zone is both fixed and known, the tension in the web material is determined from the present amount of unstrained web material in the tension zone.

因为张力区的长度固定且已知，所以可根据张力区中的非应变卷筒纸材料的当前量来确定卷筒纸材料中的张力。

The amount of web material added to, subtracted from and present in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the present amount of unstrained web material present in the tension zone.
