When suction pneumatic valve 4-3 is closed, backflush pneumatic valve 4-4 is opened and compressed air is used to backflush and clear the blockage of suction filter rod 2-6. Suction pipe 4-5 and drag chain 4-7 are fixed on suction piping mounting bracket 4-6. Suction hose 4-8 is located inside drag chain 4-7 and connected to suction pipe 4-5. Exhaust hose 4-9 is connected to exhaust port of vacuum pump 4-1 to control suction and backflush of suction filter rod 2-6.

[0028] The bag clamping tube 7-1 of the bag clamping bucket 7 is fixedly connected to the frame 1. The bag clamping bucket 7 is inserted through the lower end of the telescopic tube 2-5 of the telescopic tube assembly 2. That is, the bag clamping tube 7-1 is sleeved on the lower end of the telescopic tube 2-5 and can move with the telescopic tube 2-5 to maintain the clamping of the packaging bag.

[0029] A dust hood 8 is installed at the upper end of the bag clamping hopper 7. The dust hood 8 is connected to the telescopic pipe 2-5 and the feeding pipe 3 by rubber telescopic sleeves 5. An annular dust removal channel is left between the rubber telescopic sleeves 5 and the telescopic pipe 2-5 and the feeding pipe 3. Two dust hood limiting rods 6 are symmetrically arranged between the feeding pipe 3 and the dust hood 8. The dust hood limiting rods 6 limit the height of the dust hood 8, and a gap of 20mm-50mm (preferably 30mm) is maintained between the dust hood 8 and the bag clamping hopper 7.

[0030] The working principle of the telescopic tube feeding and air extraction device for the ton bag packaging machine provided by this utility model is as follows: Working principle: After the top opening of the packaging bag is placed on the clamping tube 7-1, the clamping clamp 7-2 clamps the top opening of the packaging bag onto the clamping tube 7-1. The side clamps hold the top opening of the packaging bag that overflows from the clamping tubes on both sides to reduce dust leakage. The slide table servo motor 2-3 starts, and the telescopic tube 2-5 extends and inserts into the bottom of the packaging bag. The material falls into the packaging bag from the feed tube 3. When the material has passed the suction filter rod 2-6, the vacuum pump 4-1 starts, and the suction pneumatic valve 4-3 opens to perform suction. At the same time, the telescopic tube 2-5 slowly retracts and rises according to the material level. After all the measured amount of material has fallen into the packaging bag, the suction pneumatic valve 4-3 closes. -3 is closed, vacuum pump 4-1 stops, telescopic tube 2-5 is fully retracted and reset, side clamp 7-4 is released, bag clamp 7-2 is released, and the telescopic tube feeding and air extraction device of the ton bag packaging machine completes the bottom feeding and air extraction process of the bag. When the air extraction filter rod 2-6 is blocked, with the packaging bag already clamped, the telescopic tube 2-5 not extended, and the air extraction pneumatic valve 4-3 closed, the back-blowing pneumatic valve 4-4 is opened, and compressed air back-blowing the air extraction filter rod 2-6 to clear the blockage. After the back-blowing is completed, the back-blowing pneumatic valve 4-4 is closed, and the above feeding and air extraction process is repeated for packaging.
