| 目的 保证热合包装机横封室的瞬时线速度与料袋膜的进给速度相一致。 方法 设计一种能自动纠偏的装置, 并且在 EPC 系统中用 PLC 对纠偏装置进行控制,并对磁粉制动器作为执行元件的胶辊式张力控制系统进行探讨。 结果 该方案可以使其在拉膜机构中与料袋膜的进给速度相适应,而且在实际运行中,控制信号与跑偏方向关系也和假设相一致。 结论 实践证明该系统能使生产线获得更高的运行速度和更好的稳定性。 |

| Objective To assure that the instantaneous linear rate of the transverse seal chamber is the same as the feed rate of the film in the hot-seal packing machine. Methods A device capable of automatic error correcting was designed. The error correcting device was controlled using PLC in the EPC system. The system of tension controlled by the rubber-roll axis was investigated in which a magnetic powder brake was used as an executive element of tension. Results The scheme resulted in compliance of the film-drawing mechanism and the feed rate of the film. Conclusion The practical running results showed that the control system could grant the production line with higher operation speed and better stability. |
