| 目的 研究四辊无芯复卷技术应用的可行性及适用性。方法 首先基于纸张张力原理推导四轴无芯机构复卷的条件，然后使用RecurDyn软件进行仿真试验，最后设计生产设备并进行调试验证。结果 在RecurDyn软件的仿真分析中，0.1～0.25 mm厚度的纸张可以完成复卷，厚度0.05 mm和0.3 mm的纸张在改变张力后，可以完成复卷。在设备试机过程中，对不同定量纸张的样品进行了复卷试验，初始设计设备对于80～180 g/m2的纸张均成功复卷，250 g/m2的样品在设备改变齿比后成功复卷，不改变齿比时，60 g/m2的样品复卷失败。结论 四轴无芯起卷技术可以应用在复卷机上完成无芯复卷作业，但也有一定的局限性。 |

| Abstract: |
| The paper studies the feasibility and applicability of the technology of rewinding by four coreless rollers. Firstly, conditions for rewinding by four coreless rollers were derived based on the theory of the paper tension principle. Then simulation experiments were done by RecurDyn software. Finally production equipment was designed and then debugged and verified. In the simulation analysis by RecurDyn, 0.1~0.25 mm thick sheet could be rolled up; 0.05 mm and 0.3 mm thick sheets could also be rolled up after tension was changed. During the debugging of equipment, samples with different specifications were rewound. The initially designed equipment enabled 80~180 g/m2 sheet to be rolled up, 250 g/m2 sheet rolled up after teeth rate was changed, and 60 g/m2 sheet failed. In conclusion, the technology of rewinding by four coreless rollers can be used in a rewinder but also has some limitations. |
