翻领成型器是充填封口机把塑料薄膜折弯成袋的专用装置,它对包装袋的形式、尺寸和产品质量等均有直接影响。目前,翻领成型器结构的设计,通常是借助理论公式逐点计算的方法,最后将所得的计算点连接成翻领曲线(见参考文献〔2〕)采用这种方法计算出的曲线不是唯一的结果,而且翻领曲线对塑料薄膜的牵引过程中阻力并不一定是最小。本文从减小翻领成型器结构对塑料薄膜的阻力着眼,介绍优化计算翻领曲线的方法。
The lapel former is a special device used to bend the plastic film into a bag by the filling and sealing machine, which has a direct impact on the form, size and product quality of the bag. At present, the design of the lapel former structure is usually calculated point by point by the theoretical formula, and finally the calculated points are connected into a lacrimal curve (see reference [2]). The curve calculated by this method is not the only one , And lapel curve on the plastic film traction resistance is not necessarily the smallest. In this paper, reducing the resistance of lap former structure to plastic film focuses on the method of optimizing the calculation lapel curve.
