Full-automatic ton bag filling machine

[0045] Example 2:

[0046] Further, the present invention also provides a preferred embodiment of the working process of the equipment. The present invention takes a packaging bag filled with 500Kg as an example, through the sorting device 3 or the packaging bag feeding device, the packaging bag of a single layer is covered. Set on the barrel 202, the splints 203 on both sides of the barrel 202 are shrunk inward to clamp the packaging bag on the barrel 202, and at the same time blow air into the packaging bag through the barrel 202, so that the packaging bag can be Expansion forming to avoid filling failure due to small internal space of the packaging bag; when the powder is filled to a certain value (usually tens of kilograms), the lifting seat 201 will be lowered on the base frame 1 to make The bottom of the packaging bag can contact the third conveying device 7 below and provide data to the weighing device; after further filling, (in this embodiment, it can be about 350 kilograms) the lifting seat 201 has As the packaging bag descends, the bottom of the packaging bag is fully contacted with the third conveying device 7, and the packaging bag is kept in a relatively regular cylindrical shape. Vibration and compaction; after further filling, (usually 480Kg), the push plate 213 suspends the vibration and compaction, and the splint 203 releases the bag mouth of the packaging bag, so that the packaging bag completely falls on the third conveying device 7 , so that the weighing device can accurately measure the weight inside the packaging bag, and then the splint 203 mechanism clamps again for filling; after filling to a weight of about 498Kg again, the splint 203 is loosened to make the weighing The mechanism can accurately measure the weight of the powder, and reduce the speed of the powder filling process by reducing the rotation speed of the powder feeding device or switching the powder source of the powder feeding device, so that the filling process is about to end. The final amount of powder is controlled, and at the same time, the beating rod 211 also starts to work to knock off the powder on the inner wall of the barrel 202 to avoid waste. When the weighing device weighs 500Kg, the feeding device and the beating rod 211 stop working completely, the clamping plate 203 is clamped again, and the pushing plate 213 is working again, so that the powder inside the packaging bag is completely compacted, and finally the third The conveying device 7 transfers the bag to the next process for further processing.
