The bottom of the inner barrel 4 and the bottom of the outer barrel 5 are both welded to the bottom of the material barrel, and the top edge of the outer barrel 5 is bent inward into a cone shape and then welded to the top of the inner barrel 4, thereby forming a closed cavity between the inner barrel 4 and the outer barrel 5, which is a negative pressure cavity. The barrel wall of the inner barrel 4 is evenly distributed with holes in the axial and circumferential directions, and the side wall of the outer barrel 5 is penetrated and welded with an exhaust pipe 8 connected to the negative pressure cavity, and the exhaust pipe 8 is connected to the exhaust equipment in the workshop.

[0028] A conical discharge hopper 2 is provided above the opening of the barrel, with the large diameter end of the discharge hopper 2 facing downward, and a discharge port is provided at the top of the discharge hopper 2. A horizontal discharge pipe 1 welded to the discharge hopper 2 is provided at the discharge port, and the middle part of the discharge pipe 1 is connected to the discharge port. The barrel is also provided with a driving device for driving the discharge hopper 2 to move vertically. The driving device is a cylinder A 3 vertically fixedly arranged on the outside of the outer tube 5. There are three cylinders A 3 distributed along the circumferential direction of the outer tube 5. The cylinder bodies of the cylinders A 3 are fixedly connected to the outer tube 5 by screws, and the push rods of the cylinders A 3 are fixedly connected to the discharge hopper 2 by screws.

A reduction motor 6 is fixedly connected to the outer side of one of the supporting legs 7 by screws. The output shaft of the reduction motor 6 passes through the supporting legs 7 and is fixedly connected to the outer cylinder 5. When the reduction motor 6 rotates, it drives the barrel to rotate vertically.

[0030] The exhaust pipe 8 is connected to the other supporting leg 7 in a through-rotating manner.

[0031] The bottom of the barrel is provided with a bag extraction pipe 9, which is welded through the bottom of the barrel and communicates with the inside of the barrel. The discharge pipe 1 is provided with electric valves 10 near both ends.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the discharge hopper 2 includes a conical cone cap 201 with the tip pointing upward and an annular brim 202 welded to the bottom of the cone cap 201. The discharge port is located at the top of the cone cap 201, and the push rod of the cylinder A 3 is fixedly connected to the corresponding lugs on the brim 202 through nuts.

[0033] The bag opening device includes a fixed sleeve 1109 axially arranged in the discharge hopper 2, a bag breaking rod 1108 axially penetrating and slidably connected to the fixed sleeve 1109, and a cylinder B 1101 fixedly arranged on the discharge hopper 2 and capable of driving the bag breaking rod 1108 to move axially. A radial cross beam 1105 is arranged between the fixed sleeve 1109 and the cone cap 201. The cross beam 1105 is three and is distributed at intervals of 120 degrees. The fixed sleeve 1109 and the cone cap 201 are respectively welded to both ends of the cross beam 1105, and the lower end of the bag breaking rod 1108 is a cone tip.

[0034] Three bag-supporting rods 1106 are evenly distributed in the circumferential direction in the discharge hopper 2.

The ends of the bag-supporting rods 1106 corresponding to the bag-breaking rod 1108 are cut with an oblique angle. A connecting rod A 1107 is provided between the bag-supporting rods 1106 and the bag-breaking rod 1108. One end of the connecting rod A 1107 is hinged to the bag-breaking rod 1108, and the other end is hinged to the middle of the bag-supporting rod 1108. The hinged position of the connecting rod A 1107 and the bag-breaking rod 1108 is located below the fixing sleeve 1109.

[0035] The cone cap 201 is welded with a bearing seat 1102 on the outside. The bearing seat 1102 is connected to a rotating shaft 1112 that is vertical to the bag breaking rod 1108. The rotating shaft 1112 and the cone cap 201 are connected through, and the rotating shaft 1112 and the discharge hopper 2 are clearance-matched. The inner end of the rotating shaft 1112 is provided with a swing arm 1110 with one end vertically fixedly connected to it through a nut.

[0036] The working process of the present invention is:

[0037] 1. Close the two electric valves 10, start the reduction motor 6, drive the barrel to rotate vertically, and make the discharge hopper 2 upward;

[0038] 2. Cylinder A3 moves to lift the discharge hopper 2 upward;

[0039] 3. Place the packaging bag containing the powdered material into the inner cylinder 4;

[0040] 4. Start the vacuum equipment in the workshop, open the valve connected to the vacuum pipe 8 on the vacuum pipeline, close the valve connected to the bag suction pipe 9 on the vacuum pipeline, and adsorb the packaging bag on the inner wall of the inner tube 5 so that the packaging bag is in close contact with the inner wall of the inner tube 5;

[0041] 5. Cylinder A 3 moves downward to make the cone cap 201 close to the inclined surface at the top of the outer cylinder 5, and then the reduction motor 6 is started to drive the barrel to rotate vertically, so that the discharge hopper 2 is downward;

[0042] 6. The air cylinder 1101 is actuated to drive the bag-breaking rod 1108 to move toward the packaging bag and insert into the packaging bag, thereby forming a breach in the packaging bag. Meanwhile, the three bag-supporting rods 1106 are inserted into the breach and driven by the bag-breaking rod 1108 to expand the breach outward.

[0043] 7. Open the two electric valves 10, and introduce compressed air into one end of the discharge pipe 1 to discharge the powdered material falling into the discharge hopper 2. The other end of the discharge pipe 1 is connected to the production equipment;

[0044] 8. After the materials in the packaging bag are put into use, close the valve connected to the vacuum pipe 8 on the vacuum pipeline, open the valve connected to the bag extraction pipe 9 on the vacuum pipeline, and under the action of negative pressure, the empty packaging bag is extracted by the bag extraction pipe 9.

[0045] After the packaging bag is adsorbed on the inner wall of the inner tube 5 by negative pressure, the hole on the inner tube 5 is covered. After that, the packaging bag is kept in close contact with the inner tube 5 by negative pressure, and the air in the inner tube 4 no longer enters the negative pressure chamber through the hole. After compressed air is introduced into one end of the discharge pipe 1, part of the compressed air enters the packaging bag to inflate the packaging bag, and part of the compressed air is used to blow out the material in the discharge hopper 2.

[0046] Since the packaging bag is adsorbed on the inner wall of the inner tube 4, a portion of compressed air enters the packaging bag to prop up the inside of the packaging bag when feeding, thereby reducing the residual powdery material in the packaging bag.
