KONTINUIERLICH BETAETIGBARE ABDICHTMASCHINE MIT ABDICHTRAD

摘要

A continuous sealing machine with an improved sealing wheel 49 comprises two single conducting rings 42, 43 connecting positive and negative electrodes 411, 412 from power supply to an electric heater 40 which is inside the sealing wheel 49 so that wheel 49 can seal and emboss the mouths of bags. An insulating ring 44 is inserted between rings 42, 43 to insulate electrodes 411, 412 which function as ring supports. Rings 42, 43 have screw holes 421, 431 to provide bolts 422, 432 connecting electric wires 423, 433 which pass through slots 451 of shaft post 45 and which connect to heater 40. Wheel 49 is fixed at shaft 45 which has at one end a sprocket wheel 46 and another end passing through the bearing of a fixed disc 48 to rotate therein.
