一种新型的高速邮资机自动供墨技术

Automatic ink-supply technology of high-speed franking machine

邮资机是目前国内外广泛使用的邮政自动化设备,其中,供墨方式的好坏将直接影响到其工作效率。针对目前的高速邮资机自动供墨机构存在的供墨不均匀、维护不方便并且供墨量不可控等问题,提出了一种新型的电磁柱塞式自动供墨系统,该系统采用电磁铁吸合带动电磁衔铁芯在油墨泵内往复运动,通过改变电磁铁的吸合频率可以达到控制供墨量的目的,确保供墨均匀。研究结果表明其具有结构简单、维护方便等特点,解决了传统供墨机构的不足,具有良好的应用前景。

Franking machine is an automatic postal equipment which was used widely in nowadays.Ink-supply system is one of the most decisive factors affecting the work efficiency of franking machine.Aiming at the shortcomings existed in the present automatic ink-supply system such as uneven ink-supply,inconvenient maintenance,a new kind of automatic ink-supply system with electromagnetic plunger was brought forward.Even and quantitive ink-supply were realized by controlling the electromagnet on and off.The results indicate that the shortcomings of traditional ink-supply system are made up,and the new technology has a good prospect of application.
