塑料薄膜制品在生产过程中和最终包装出厂时,为了将其平整地卷成圆筒形状,广泛使用了卷取装置。根据工作原理,卷取装置可分成表面卷取和中心卷取两种类型,前者由于具有结构简单、易于实现恒线速卷取、设备价格低廉、维修方便等优点,且因卷取辊支承于主动滚筒上而几乎不受弯曲,使卷取辊不需要很大的刚度而能获得良好的卷取质量,因而这种卷取方式得到了更多的应用。其最常见的结
Plastic film products in the production process and the final package at the factory, in order to roll it flat into a cylindrical shape, widely used winding device. According to the working principle, the winding device can be divided into two types: surface winding and center winding. The former has the advantages of simple structure, easy realization of constant linear speed winding, low equipment cost, convenient maintenance and the like, The take-up roller is almost free from bending, so that the take-up roller does not require a great rigidity and can obtain good take-up quality, so that the take-up method has been more applied. Its most common knot
