An arc-shaped hollow bag making machine 500 is further arranged on the case 100, and the packaging bag generated by the slitting mechanism 300 finally moves to the position right below the bag making machine 500 (not shown in the figure). At this time, the filling apparatus in fig. 1 is in a standby state.
As shown in fig. 2, the discharging mechanism 200 includes a sliding member 210 for moving the discharging mechanism 200 in the front-rear direction (toward or away from the bag making machine 500), the sliding member 210 being mounted on the top end of the casing 100; a hopper member 5 for feeding the packaging bag; a support column 220 having one end connected to the hopper member 5; a hopper arm member 230 for rotating and/or moving up and down the hopper member 5 around the slide member 210, the hopper arm member 230 being provided at the upper end of the slide member 210 and connected to the other end of the support column 220. At this time, the discharging mechanism 200 of the filling device in fig. 2 is at a filling position for the packaging bag, and the expected discharging mechanism 200 can slide back and forth through the sliding component 210, so that a more accurate calibration position can be ensured, and the discharging hole of the discharging mechanism 200 can be aligned with the inlet of the bag making device 500, so that granular or powdery materials can be fed into the packaging bag.
As shown in fig. 2,3, and 4, the sliding member 210 includes a guide rail 211; a slider 212 slidably engaged with the guide rail 211; the upright post 213 is arranged on the slide block 212, and the upright post 213 is provided with a fastening handle 214 which can lock the sliding position of the upright post 213, so that the blanking mechanism 200 is prevented from sliding after calibrating the working position. The hopper arm member 230 includes a hopper arm 231, the hopper arm 231 being rotatably provided at an upper end of the upright 213; a height adjusting unit 232 which can move the hopper arm 231 in the up-down direction by rotation, the height adjusting unit 232 being provided in the hopper arm 231; the hand wheel 233, the hand wheel 233 is connected with the height adjusting unit 232, and the height adjusting unit 232 can be driven to rotate by rotating the hand wheel 233.
