Description

一种可伸缩夹爪组及烟草夹持装置及其使用方法 技术领域
本发明属于设备领域，尤其涉及一种可伸缩夹爪组及烟草夹持装置及其使用方法。
背景技术
目前卷烟厂复烤车间的打叶复烤配方组模是采用人工配方组模方式。存在劳动用工量大、配方均匀性低、增加生产环境粉尘等诸多问题。烟草来料时，通常是用纸箱打包的，需要人工拆箱，然后搬运到电子皮带秤上进行上料。
针对于人工配方组模方式的弊端，开发了烟草夹持夹爪。但使用夹爪可以自动夹持烟草，但是同样存在问题。例如，根据生产车间的不同情况，需要夹持的烟草的量也会不同；烟草刚来料时，需要夹持的烟草的量很大，而烟草快夹持完毕时，能够夹持的烟草的量又很少，现有技术的烟草夹持夹爪难以适应不同的夹持总量的烟草。为解决上述问题提出本发明。
