[0036] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0037] It should be noted that these drawings are simplified schematic diagrams, and only illustrate the basic structure of the present application in a schematic manner, and therefore only show the relevant components of the present application.

[0038] Referring to Figures 1-4 The automatic bagging device of the small material batching and weighing equipment disclosed by the present application comprises a conveying mechanism 10, a U-shaped frame 2 is symmetrically arranged on the outer side of the conveying mechanism 10, a jacking mechanism 30 is installed below the conveying mechanism 10, a mouth opening mechanism 40 is connected between the U-shaped frames 2, a lifting type blowing and pressing mechanism 50 is arranged above the mouth opening mechanism 40, the lifting type blowing and pressing mechanism 50 comprises a U-shaped seat 51, an annular blowing assembly 52 and a telescopic rod piece one 53 connected to the top of the U-shaped seat 51, the two ends of the U-shaped seat 51 are respectively connected to the U-shaped frames 2, the annular blowing assembly 52 comprises an annular pipe 521 and a mounting seat 522, a plurality of connecting rods 523 connected to the inner side of the annular pipe 521 are annularly arranged on the outer circle of the mounting seat 522, a plurality of blowing heads 524 are connected to the bottom of the annular pipe 521, a connecting head 525 is installed at the top, the connecting head 525 is connected to an external blowing pump through a hose, and the bottom end of the blowing head 524 is inclined downward away from the center of the annular pipe 521.

[0039] Further, the external mechanical hand places the distributed packaging bag at the corresponding position of the mouth opening mechanism 40, so that the mouth opening mechanism 40 effectively opens the bag opening of the packaging bag, and the annular blowing assembly 52 is driven by the telescopic rod member I 53 to move downward, and enters the inner cavity bottom of the packaging bag along the bag opening. The telescopic rod member I 53 is a servo electric cylinder, air cylinder or oil cylinder, which fully expands the inner space of the packaging bag. At this time, the conveying mechanism 10 transmits the placing shell to the specified position and accurately positions it. The lifting mechanism 30 lifts the placing shell to the working position of the mouth opening mechanism 40, so that the packaging bag is sleeved on the surface of the placing shell. Then, the blowing head 524 on the annular blowing assembly 52 blows air to the bag opening of the packaging bag, so that it is tightly attached to the inner wall of the placing shell. In addition, since the bottom end of the blowing head 524 is inclined downward away from the center of the annular pipe 521, the blowing head 524 can change the jet direction of the airflow, so that the bottom position of the packaging bag is attached to the surrounding area of the inner cavity bottom wall of the placing shell.

[0040] The mouth opening mechanism 40 includes symmetrically arranged connecting plates 41, and the opposite sides of the connecting plates 41 are respectively provided with telescopic suction assemblies 42. The connecting plates 41 are symmetrically provided with mouth opening assemblies 43 between them, and the telescopic suction assemblies 42 are respectively located between the mouth opening assemblies 43. The telescopic suction assembly 42 includes a mounting plate 421 and a telescopic rod member II 422 for driving the mounting plate 421 to move back and forth. A plurality of suction cups 423 are connected to the mounting plate 421 at intervals. One end of the suction cup 423 is connected to an external air pump through a hose. The telescopic rod member II 422 includes an electric push rod 4221 and symmetrically arranged guide rods I 4222. One end of the electric push rod 4221 and the guide rods I 4222 is connected to the mounting plate 421. The mouth opening assembly 43 includes a rotating shaft 431, and a plurality of flaps 432 are arranged at intervals on the outer circle of the rotating shaft 431. The mouth opening assembly 43 further includes a servo motor 433 connected to the side of the mounting plate 421 away from the suction cup 423. One end of the rotating shaft 431 is connected to the output shaft of the servo motor 433, and the other end is rotatably connected to the connecting plate 41.

[0041] Further, the suction cups 423 are connected with an external air suction pump through a hose. When the air suction pump is started, a negative pressure is formed inside the suction cups 423, so that the suction cups 423 have the adsorption capacity to adsorb the packaging bag. In cooperation with the other telescopic adsorption assemblies 42, the electric push rod 4221 drives the mounting plate 421 and the suction cups 423 thereon to move towards the packaging bag. After the suction cups 423 contact the surface of the packaging bag, the packaging bag is firmly adsorbed on the mounting plate 421 due to the action of the negative pressure. At this time, the two telescopic adsorption assemblies 42 respectively drive the mounting plate 421 and the suction cups 423 thereon to move in opposite directions. Since the suction cups 423 are arranged in pairs and move in opposite directions respectively, they will generate a stretching force on both sides of the packaging bag, so as to open the bag opening of the packaging bag. The flap 432 is driven by the servo motor 433 to rotate the rotating shaft 431 and the flap 432 thereon to rotate. In the rotating process, the flap 432 folds and unfolds the bag opening of the packaging bag which has been opened, so as to cooperate with the jacking mechanism 30 to drive the placement shell to move upwards, so as to match the placement shell with the packaging bag, so as to ensure that the packaging bag can be stably sleeved on the placement shell, thereby preparing for the subsequent blowing and pressing or other operations.

[0042] The conveying mechanism 10 comprises conveying frames 11, and a plurality of electric rollers 12 are installed between the conveying frames 11 at intervals. The jacking mechanism 30 comprises a support platform 31 and a push plate 32. The bottom of the push plate 32 is connected with guide rods two 33, and the guide rods are respectively arranged on the support platform 31. The top of the push plate 32 is connected with a plurality of support blocks 34, and the support blocks 34 are respectively located between adjacent two electric rollers 12. The bottom of the support platform 31 is connected with an electric cylinder 35, and the extending end of the electric cylinder 35 is connected with the push plate 32.

[0043] Further, when the electric cylinder 35 drives the push plate 32 and the support blocks 34 to move upwards, the placement shell moves upwards, so as to make the bottom of the packaging bag contact the bottom of the inner cavity of the placement shell, so that the telescopic rod one 53 drives the annular blowing assembly 52 to move downwards and extend into the inner cavity of the packaging bag at the bag opening. The bottom of the annular blowing assembly 52 does not contact the placement shell, so as to avoid damage to the equipment or damage to the packaging bag due to collision.

[0044] The implementation principle of the embodiment is that: in use, other automatic devices such as external mechanical arms transport the distributed packaging bag to the telescopic suction assembly 42, and the placing shell for accommodating the packaging is conveyed to the corresponding working area of the mouth opening assembly 43 by the electric roller 12, and the size of the packaging bag is larger than that of the placing shell, at this time, the external air pump forms negative pressure in the suction disc 423 through the hose, one of the telescopic suction assemblies 42 is adsorbed to the packaging bag, and the electric push rod 4221 of the other telescopic suction assembly 42 drives the mounting plate 421 and the suction disc 423 thereon to move to the packaging bag, and after contacting with the packaging bag, the two telescopic suction assemblies 42 are moved in opposite directions respectively, so that the stretching force is generated on both sides of the packaging bag, so that the bag opening of the packaging bag is opened, at this time, the servo motor 433 drives the rotating shaft 431 and the flap 432 thereon to rotate, the flap 432 is folded and unfolded in the rotating process, and the telescopic rod piece one 53 drives the annular pipe 521 to move downward, and the annular pipe 521 is inserted into the inner cavity bottom of the packaging bag along the bag opening, so that the inner side space of the packaging bag is fully unfolded, and the electric cylinder 35 drives the pushing plate 32 and the supporting block 34 to move upward, so that the placing shell is upwardly ensured to be stably sleeved on the placing shell, then the blowing head 524 blows air to the bag opening of the packaging bag, so that the bag opening of the packaging bag is tightly attached to the inner wall of the placing shell, and in addition, since the bottom end of the blowing head 524 is inclined downward away from the center of the annular pipe 521, the blowing head 524 can change the jet direction of the airflow, so that the bottom position of the packaging bag is attached to the surrounding area of the inner cavity bottom wall of the placing shell.

[0045] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
