[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the rotary flexible packaging mechanism, the flexible transmission component supports the bag grasping component; when the bag grasping component moves to one side of the bag taking component, the support track provides limit support for the first slider and the second slider at the bottom of the first slide plate and the second slide plate. The first slide plate and the second slide plate are meshed with the central gear through the racks arranged at the top to form a linkage structure. When the included angle between the first swing arm and the second swing arm on the connecting shaft increases, the second slide plate will move away from the central gear along the support track under the action of the second swing arm. At the same time, through the continuous meshing of the rack and the gear, the first slide plate moves away from the gear under the action of the rack. At this time, the top pressing plates on the first slide plate and the second slide plate will squeeze the opening claw pressing wheel, and then under the action of the opening claw push rod, the clamping claws are pushed open to realize the automatic opening claw process. The installation pillar and the installation plate serve as the main support structures of the bag grasping component. The lifting guide rail and the lifting slider on the installation plate are connected to the lifting plate as the lifting structure of the bag taking suction nozzle. At the same time, the synchronous pulley and the synchronous belt are used to adjust the position of the push plate relative to the roller bracket, so as to adjust the position of the bag taking suction nozzle according to the actual size of the bag. After the adjustment is completed, the pushing cylinder is used to push the pushing shell outwards, and the bag taking suction nozzle on the pushing shell is used to take the bag and push the bag into the clamping claws. Then, when the included angle between the first swing arm and the second swing arm on the connecting shaft decreases, the opening claw pressing wheel disengages from the top pressing plate, and the clamping claws return under the action of the clamping spring and cooperate with the support arm to complete the bag grasping process; when the bag grasping component moves to one side of the bag opening component, the right shaft sleeve and the left shaft sleeve respectively provide rotational support for the right turning frame and the left turning frame. At the same time, the right turning frame and the left turning frame are rotationally connected by the connecting piece to form a symmetrical linkage structure. During the use process, the bag opening motor drives the eccentric bushing to rotate, pulling the bottom end of the guide rod to move, and then driving the right turning frame to rotate through the guide rod. With the symmetrical linkage structure, the suction tubes on the right turning frame and the left turning frame approach each other to adsorb the two sides of the top of the bag respectively. Then the bag opening motor drives the eccentric bushing to reverse, and the suction tubes on both sides move away from each other to automatically complete the bag opening process; when the bag grasping component moves to the bottom of the powder filling component, the servo motor and the reducer are respectively fixedly supported in the motor enclosure by the motor fixing seat and the stud. The servo motor, as the power input of the reducer, conducts the torque to the output gear at the output end of the reducer. Then the output gear drives the transmission shaft to rotate through the chain belt. During the rotation of the transmission shaft, the spiral frame is driven to rotate by the side rod, so that the powder is discharged from the discharge nozzle at the bottom of the discharge hopper, automatically completing the powder distribution process without manual ladling operation, which can become an automatic process during the operation of the packaging machine. At the same time, the discharge hopper and the feed hopper form a closed structure at the bottom of the discharge bottom plate, and the sealing effect is improved by the sealing ring at the top of the discharge hopper and the clamp at the bottom of the discharge hopper, avoiding the powder from getting damp and caking or being contaminated during the distribution process;When the bag-grabbing assembly moves to the sealing assembly, the swing rod shaft serves as the rotational support of the swing rod frame. During the rotation of the swing rod frame, the first connecting rod and the second connecting rod symmetrically and rotatably connected to the top and bottom of the swing rod frame will drive the first pulling arm and the second pulling arm to move relatively in opposite directions. During use, the sealing air cylinder is used as the power input to drive the air cylinder gasket and the air cylinder joint to move up and down to realize the rotation of the swing rod frame. Then, the knife seat baffle, the heat insulation plate, and the sealing knife seat on both sides are driven by the first pulling arm and the second pulling arm to approach each other. After squeezing the bag mouth, it cooperates with the temperature controller to achieve automatic sealing. During the packaging process, the endless conveyor belt in the flexible transmission assembly drives the bag-grabbing assembly to perform a circular operation around the top of the rotating platform, successively passing through the bag-taking assembly, the bag-opening assembly, the filling assembly, and the sealing assembly to complete the whole process of bag-taking, bag-clamping, opening, filling, and sealing, adapting to the fast production process, saving manpower and material resources, and improving work efficiency.

[0036] Working principle: The flexible transmission component 1 supports the bag grasping component 3; when the bag grasping component 3 moves to one side of the bag taking component 2, the support rail 302 provides limit support for the first slider 303 and the second slider 304 at the bottom of the first slide plate 305 and the second slide plate 306. The first slide plate 305 and the second slide plate 306 are engaged with the central gear 311 through the racks 310 arranged at the top to form a linkage structure. When the angle between the first swing arm 307 and the second swing arm 309 on the connecting shaft 308 increases, the second slide plate 306 will move away from the central gear 311 along the support rail 302 under the action of the second swing arm 309. At the same time, through the continuous engagement of the rack 310 and the central gear 311, the first slide plate 305 moves away from the central gear 311 under the action of the rack 310. At this time, the top pressing plates 312 on the first slide plate 305 and the second slide plate 306 will squeeze the opening claw pressing wheel 315, and then under the action of the opening claw push rod 317, the clamping claws 319 are pushed open to complete the automatic opening claw process. The installation support column 201 and the installation plate 202 are used as the support structure. The lifting guide rail 203 and the lifting slider 204 on the installation plate 202 are connected to the lifting plate 205 as the lifting structure of the bag taking suction nozzle 221. At the same time, the synchronous pulley 209 and the synchronous belt 210 are used to adjust the position of the push plate 211 relative to the roller bracket 206, so as to adjust the position of the bag taking suction nozzle 221 according to the actual size of the bag. After the adjustment is completed, the pushing cylinder 219 is used to push the top pushing shell 216 to move outwards, and the bag taking suction nozzle 221 on the top pushing shell 216 is used to take the bag and push the bag into the space between the clamping claws 319. Then, the angle between the first swing arm 307 and the second swing arm 309 on the connecting shaft 308 decreases, the opening claw pressing wheel 315 disengages from the top pressing plate 312, and the clamping claws 319 return to their positions under the action of the clamping spring 316 and cooperate with the support arm 313 to complete the bag grasping process; when the bag grasping component 3 moves to one side of the bag opening component 4, the right shaft sleeve 408 and the left shaft sleeve 412 respectively provide rotational support for the right turning frame 407 and the left turning frame 411. At the same time, the right turning frame 407 and the left turning frame 411 are rotationally connected by the connecting piece 410 to form a linkage symmetric structure. During use, the bag opening motor 404 drives the eccentric bushing 405 to rotate, pulling the bottom end of the guide rod 406 to move, and then driving the right turning frame 407 to rotate through the guide rod 406. With the linkage symmetric structure, the suction bag tubes 415 on the right turning frame 407 and the left turning frame 411 approach each other to adsorb both sides of the top of the bag respectively. Then, the bag opening motor 404 drives the eccentric bushing 405 to reverse, making the two suction bag tubes 415 move away from each other, automatically completing the bag opening process;When the bag grabbing assembly 3 moves to the bottom of the powder filling assembly 5, the servo motor 504 and the reducer 505 are respectively fixed and supported in the motor enclosure 507 by the motor fixing base 502 and the stud 506. The servo motor 504, as the power input of the reducer 505, conducts the torque to the output gear 508 on the output end of the reducer 505. Then, the output gear 508 drives the transmission shaft 509 to rotate through a chain belt. During the rotation of the transmission shaft 509, the spiral frame 511 is driven to rotate by the side rod 510, so that the powder is discharged from the discharge nozzle 512 at the bottom of the discharge hopper 513, automatically completing the powder distribution process without manual scooping operation, which can become an automated process during the operation of the packaging machine. At the same time, the discharge hopper 513 and the feed hopper 515 form a closed structure at the bottom of the discharge bottom plate 501, and the sealing ring 517 at the top of the discharge hopper 513 and the clamp 514 at the bottom of the discharge hopper 513 are used to improve the sealing effect and prevent the powder from getting damp and caking or being contaminated during the distribution process; when the bag grabbing assembly 3 moves to the sealing assembly 6, the swing rod shaft 605 serves as the rotation support of the swing rod frame 604. The first connecting rod 606 and the second connecting rod 607 symmetrically and rotatably connected to the top and bottom of the swing rod frame 604 will drive the first pull arm 608 and the second pull arm 609 to move relatively in opposite directions during the rotation of the swing rod frame 604. During use, the sealing cylinder 601 is used as the power input to drive the cylinder gasket 602 and the cylinder joint 603 to move up and down to realize the rotation of the swing rod frame 604, and then drive the knife seat baffles 624, the heat insulation plates 625 and the sealing knife seats 626 on both sides to approach each other through the first pull arm 608 and the second pull arm 609. After squeezing the bag mouth, the automatic sealing is realized in cooperation with the temperature controller 621; during the packaging process, the endless conveyor belt 106 in the flexible transmission assembly 1 drives the bag grabbing assembly 3 to perform a circular operation around the top of the rotating platform 105, successively passing through the bag taking assembly 2, the bag opening assembly 4, the powder filling assembly 5 and the sealing assembly 6 to complete the whole process of bag taking, bag clamping, opening, filling and sealing, adapting to the fast production process, saving manpower and material resources, and improving work efficiency.
