Sealing machine

The utility model discloses a sealing machine controls vertical lift of press device and flexible press device through electromagnet device, and flexible press device can drive the lead screw through manual carousel transmitting?gear again and stretch out and draw back and control the distance between press device and the flexible press device, no matter the material length of coming the assurance to seal can both firmly be placed on the strip that generates heat, the material that can not lead to sealing produces skew when sealing, in addition cause seal firm. 本实用新型公开了封口机，通过电磁铁装置来控制按压装置和伸缩按压装置的纵向升降，且伸缩按压装置又能通过手动转盘转动齿轮带动丝杆伸缩来控制按压装置和伸缩按压装置之间的距离，来保证需要封口的物料不论长短都能牢牢放置在发热条上，不会导致需要封口的物料在封口时产生偏移，甚至造成封口不牢。
