[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: in this rotary flexible packaging mechanism, the bag grabbing assembly is supported by a flexible transmission assembly; when the bag grabbing assembly moves to one side of the bag taking assembly, the support track provides limiting support for the first slider and the second slider at the bottom of the first slider and the second slider, and the first slider and the second slider are meshed with the central gear through the rack arranged on the top to form a linkage structure. When the angle between the first swing arm and the second swing arm on the connecting shaft increases, the second slider will move away from the central gear along the support track under the action of the second swing arm, and at the same time, through the continuous meshing of the rack and the gear, the first slider is moved away from the gear under the action of the rack, and at this time, the top pressure plates on the first slider and the second slider will squeeze The claw-opening pressure wheel is pressed, and then the clamping claw is pushed open under the action of the claw-opening push rod to realize the automatic claw-opening process. The mounting pillar and the mounting plate are used as the main supporting structure of the bag grabbing assembly. The lifting guide rail and the lifting slider on the mounting plate are connected to the lifting plate as the lifting structure of the bag-taking suction nozzle. At the same time, the synchronous wheel 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 push-out cylinder is used to push the push shell outward, and the bag-taking suction nozzle on the push shell is used to take the bag, and the bag is pushed between the clamping claws. After that, the angle between the first swing arm and the second swing arm on the connecting shaft is reduced, the claw-opening pressure wheel is separated from the top pressure plate, and the clamping claw returns to its position under the action of the clamping spring. The bag grabbing assembly cooperates with the support arm to complete the bag grabbing process; when the bag grabbing assembly moves to one side of the bag opening assembly, the right shaft sleeve and the left shaft sleeve respectively provide rotational support for the right flip frame and the left flip frame, and at the same time, the right flip frame and the left flip frame are connected by the connecting piece to form a linkage symmetrical structure. During use, the bag opening motor drives the eccentric shaft sleeve to rotate to pull the bottom end of the guide rod to move, and then drives the right flip frame to rotate through the guide rod, and the linkage symmetrical structure makes the bag suction tubes on the right flip frame and the left flip frame approach each other to absorb the two sides of the top of the bag respectively, and then the bag opening motor drives the eccentric shaft sleeve to reverse so that the bag suction tubes on both sides move away from each other, and the bag opening process is automatically completed; when the bag grabbing assembly moves to the bottom of the dispensing assembly, the motor fixes the eccentric shaft sleeve to rotate. The fixed seat and the stud respectively fix and support the servo motor and the reducer in the motor closed shell. The servo motor, as the power input of the reducer, transmits the torque to the output gear on 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 through the side rod to discharge the powder from the discharge nozzle at the bottom of the discharge hopper, automatically completing the powder distribution process without manual floating scooping operation. It can become an automated process in 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 ring at the top of the discharge hopper and the clamp at the bottom of the discharge hopper are used to improve the sealing effect to prevent the powder from getting damp, agglomerated or contaminated during the distribution process.When the bag grabbing assembly moves to the sealing assembly, the swing arm shaft serves as the rotation support of the swing arm frame. The first connecting rod and the second connecting rod connected to the top and bottom of the swing arm frame symmetrically rotate, and the first and second pulling arms are driven to move relative to each other in opposite directions during the rotation of the swing arm frame. During use, the sealing cylinder is used as the power input to drive the cylinder pad and the cylinder joint to move up and down to realize the rotation of the swing arm frame, and then the knife seat baffles, heat insulation plates and sealing knife seats on both sides are driven to approach each other through the first and second pulling arms, and the bag mouth is squeezed and then the temperature controller is used to realize automatic sealing; during the packaging process, the circular conveyor belt in the flexible transmission assembly drives the bag grabbing assembly to do a circular operation around the top of the rotating platform, and the whole process of bag grabbing, bag clamping, opening, filling and packaging is completed in sequence through the bag taking assembly, bag opening assembly, packaging assembly and sealing assembly, which is suitable for the fast production process, saves manpower and material resources, and improves work efficiency. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Working principle: The bag grabbing assembly 3 is supported by the flexible transmission assembly 1; when the bag grabbing assembly 3 moves to one side of the bag taking assembly 2, the support rail 302 provides limiting support for the first slider 303 and the second slider 304 at the bottom of the first slider 305 and the second slider 306. The first slider 305 and the second slider 306 are meshed with the central gear 311 through the rack 310 arranged on 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 slider 306 will move away from the central gear 311 along the support rail 302 under the action of the second swing arm 309, and at the same time, through the rack 31 0 is continuously meshed with the central gear 311, so that the first slide plate 305 is away from the central gear 311 under the action of the rack 310. At this time, the top pressure plate 312 on the first slide plate 305 and the second slide plate 306 will squeeze the claw opening pressure wheel 315, and then the clamping claw 319 is pushed open under the action of the claw opening push rod 317 to realize the automatic claw opening process. The mounting pillar 201 and the mounting plate 202 are used as the supporting structure. The lifting guide rail 203 and the lifting slider 204 on the mounting plate 202 are connected to the lifting plate 205 as the lifting structure of the bag taking nozzle 221. At the same time, the synchronous wheel 209 and the synchronous belt 210 are used to adjust the push plate 211 relative to the roller bracket 206. The position of the bag taking nozzle 221 is convenient for adjusting the position of the bag taking nozzle 221 according to the actual size of the bag. After the adjustment is completed, the push cylinder 219 is used to push the push shell 216 outward, and the bag taking nozzle 221 on the push shell 216 is used to take the bag, and the bag is pushed into the clamping claws 319. After that, the angle between the first swing arm 307 and the second swing arm 309 on the connecting shaft 308 is reduced, and the claw opening pressure wheel 315 is separated from the top pressure plate 312. The clamping claw 319 returns to its position under the action of the clamping spring 316 and cooperates with the support arm 313 to complete the bag grabbing process; when the bag grabbing assembly 3 moves to one side of the bag opening assembly 4, the right shaft sleeve 408 and the left shaft sleeve 412 are respectively used to turn the right The rotating frame 407 and the left flip frame 411 provide rotation support, and the connecting piece 410 is used to rotatably connect the right flip frame 407 and the left flip frame 411 to form a linkage type symmetrical structure. During use, the bag opening motor 404 drives the eccentric shaft sleeve 405 to rotate to pull the bottom end of the guide rod 406 to move, and then the right flip frame 407 is driven to rotate through the guide rod 406. With the linkage type symmetrical structure, the bag suction tubes 415 on the right flip frame 407 and the left flip frame 411 are close to each other to absorb the two sides of the top of the bag respectively, and then the bag opening motor 404 drives the eccentric shaft sleeve 405 to reverse so that the bag suction tubes 415 on both sides are away from each other, and the bag opening process is automatically completed;When the bag grabbing assembly 3 moves to the bottom of the dispensing assembly 5, the motor fixing seat 502 and the stud 506 respectively fix the servo motor 504 and the reducer 505 in the motor sealing shell 507. The servo motor 504, as the power input of the reducer 505, transmits 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 the chain belt. During the rotation of the transmission shaft 509, the spiral frame 511 is driven to rotate through the side rod 510 to make the powder from The discharge nozzle 512 at the bottom of the discharge hopper 513 discharges the powder, and the powder distribution process is automatically completed without manual scooping operation, which can become an automated process in 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 to prevent the powder from getting damp, agglomerated or contaminated during the distribution process; when the bag grabbing assembly 3 moves to the sealing assembly 6, The swing arm shaft 605 serves as the rotation support of the swing arm frame 604. The first connecting rod 606 and the second connecting rod 607, which are symmetrically connected to the top and bottom of the swing arm frame 604, will drive the first pulling arm 608 and the second pulling arm 609 to move relative to each other in opposite directions during the rotation of the swing arm 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 arm frame 604, and then the first pulling arm 608 and the second pulling arm 609 drive the first pulling arm 608 and the second pulling arm 609 to move relative to each other in opposite directions. The knife block baffles 624, heat insulation board 625 and sealing knife block 626 on both sides are close to each other, and after squeezing the bag mouth, they cooperate with the temperature controller 621 to realize automatic sealing; during the packaging process, the ring conveyor belt 106 in the flexible transmission component 1 drives the bag grabbing component 3 to make a ring operation around the top of the rotating platform 105, and successively passes through the bag taking component 2, the bag opening component 4, the packaging component 5 and the sealing component 6 to complete the whole process of bag taking, bag clamping, opening, filling and packaging, which is suitable for the fast production process, saves manpower and material resources, and improves work efficiency. ;
