Abstract
本发明涉及一种密封件,用它将检测空气引导到烟草加工工业中的棒状物,或自棒状物引出。密封件由弹材料制成,它有可轴向移动的底板,底板上有检测空气流动的通孔,它还有一个依底板的移动而径向变形的环状密封唇。通过本发明使由于被检测物锋利边缘而造成的密封件损坏的危险减小。根据本发明是在密封唇(9)和底板(4)与棒状物(8,8a)相邻的侧面(9a及4a)交界处的过渡区段(12)设有一个与棒形物相对的环状凹槽(13)。通过本发明使上述密封件的使用寿命大大提高。
Description
本发明涉及一种密封件,用它将检测空气引导到烟草加工工业中的棒状物,或由棒状物引出。密封件由弹性材料制成,它有可轴向移动的底板,底板上有检测空气流动的通孔,它还有一个根据底板的移动而径向变形的环状密封唇。
在美国专利US-PS4429567中,本文开始所述类型的密封件以及它在检测装置(检测筒)中的安装和它在香烟检测中的作用方式是大家所熟悉的。
本发明的任务在于对已知的密封件进一步改善,以减少棒状物对其损伤的危险。
其解决方案是,在密封唇和底板与棒形物接触面的交界区段(过渡段),设置一个与棒状物端面相对的环状凹槽。
本发明的一个有利结构方案是,环状凹槽在纵剖视图上至少呈近似半圆的形状,它主要是由橡胶,弹性塑料或硅树脂制成。
本发明的优点在于使密封件的使用寿命得到提高,因为棒状物锋利的边缘只能较慢地使构成密封件的弹性材料受到损坏。
下面借助于密封件的纵剖图,并以较大比例放大画出的结构实例对本发明作进一步说明。
用以将检测空气引导到烟草加工业中的棒状物8(例如香烟)中去的密封件1,它有一个橡胶或如橡胶弹性物质构成的中空圆筒状密封体2,弹性物质可以是一种适用的有弹性的塑料,硅树脂或类似物。一个向内伸的凸缘3用以将密封件固定在图中未标出的固定件上,固定件由金属或塑料制成,这与US-PS4429567图1相似。密封件1还有一底板4,底板上有检测空气的通孔6以及一密封唇7。当一支被测试的香烟8以其带滤嘴的端部8a相对底板4的外侧面4a按箭头10的方向推进时,密封唇7移动,从而使密封唇边缘9径向朝内移动(见箭头11),直至密封唇边缘以其环状端9a与棒状物环状上表面接触,并由此使棒形物的内腔与外部大气密封。在过渡区段12内,与棒状物8、8a相邻的底板4的侧面4a与密封唇边缘9的侧面9a相交界,此处设有相对棒状物的凹槽13,图中所示在纵剖面带有半圆形的槽具有优点,但也可以具有与所示的不相同的形状。过滤嘴端8a的锋利外边处于凹槽部位,因此为了密封而将香烟8向底板4压紧时不会导致侧面4a的损坏。
根据本发明,密封件1也可用作将检测空气由棒状物8,例如从香烟中引导出来。根据本发明,它也可以被用于其它的检测任务中,此时棒状物内部产生高压或负压,在这里将与包封状况相关的气压信号用作测试信号。
Claims (4)
1.密封件,它被用以将检测空气引导到烟草加工工业中的棒状物,或自棒状物引出,它由弹性材料制成,具有可轴向移动的底板,底板上有检测空气流动的通孔,它还有一个依底板的移动而径向变形的环状密封唇,其特征在于:在密封唇(9)和底板(4)与棒状物(8,8a)相邻的侧面(9a及4a)交界处的过渡区段(12)设有一个与棒形物端面相对的环状凹槽(13),在检测时,棒形物的环状边界边缘就位于凹槽(13)的区域内,以便减少对侧面(4a)的磨损。
2.根据权利要求1的密封件,其特征在于:环状凹槽(13)在纵剖面图上至少呈近似半圆形。
3.根据权利要求1或2的密封件,其特征在于,至少密封唇(9)是由弹性材料制成。
