Description

Technical Field

[0001] This disclosure relates to the technical field of medical devices, and in particular to a medical face mask isolation bag device. Background Technology

[0002] Medical face masks are commonly used in the medical field, such as for non-invasive ventilation, oxygen therapy, or anesthesia. The part of the mask that contacts the patient's face contains an airbag to ensure a tight seal and comfort. This airbag is often made of soft and elastic materials, such as medical-grade silicone or thermoplastic elastomers (TPE). These materials offer excellent biocompatibility and sealing performance, but their surfaces typically have a certain degree of adhesiveness.

[0003] However, in the automated production process of packing medical masks into packaging bags, due to the adhesive properties of the airbag material, the surface of the airbag is prone to sticking to the inner wall of the packaging bag, which makes it impossible for the mask to enter the packaging bag smoothly. Abnormalities such as bag position deviation, folding or bag jamming occur, which seriously affect the efficiency and pass rate of automated packaging.

[0004] For example, prior art document CN202111604355.8 discloses a bagging and sealing device and process for packaging bags, including a bag feeding device, a bag-feeding mechanism, a bag-supporting mechanism, a material pushing mechanism, a material conveying mechanism, and a sealing device. The bag feeding device is used to remove the packaging bag and convey it to the bag-removing position of the bag feeding mechanism; the bag feeding mechanism is used to open the opening of the packaging bag and place the packaging bag onto the bag-supporting mold of the bag-supporting mechanism; the material conveying mechanism is used to convey the material; the material pushing mechanism is used to push the material in the material trough of the material conveying mechanism into the packaging bag placed on the bag-supporting mold; and the sealing device is used to seal the packaging bag containing the material. This solution cannot solve the problem of adhesion between the airbag surface of the medical face mask and the packaging when packaging medical face masks, resulting in abnormalities such as mask bagging position displacement or jamming. Summary of the Invention

[0007] In one embodiment, the mask conveying mechanism includes a mask conveying assembly and a fixture assembly. The mask conveying assembly is mounted on the worktable, and the fixture assembly is placed on the mask conveying assembly. The fixture assembly is used to install the mask.

[0008] In one embodiment, the fixture assembly includes a fixture base and a support column. The support column is fixed to the surface of the fixture base and has a receiving portion for receiving a face mask. The receiving portion forms a supporting surface, and the face mask is fitted onto the support column and abuts against the supporting surface.

[0009] In one embodiment, the fixed plate assembly includes a mounting plate, a swing drive, a rotating shaft connector, and a lifting frame assembly.

[0010] In one embodiment, the gripper assembly includes a first gripper, a second gripper, and a gripper drive, wherein the gripper drive is connected to the fixed plate assembly and is used to drive the first gripper and the second gripper to move relative to each other.

[0011] In one embodiment, the mounting bracket assembly includes a bracket base and at least two opposing clamping assemblies. Each clamping assembly includes a support arm, a clamping member, and an elastic member. The elastic member abuts against the support arm and the clamping member, respectively, and is used to provide an elastic force to the clamping member that tends to press against the edge of the bag opening.

[0012] In one embodiment, the bag opening mechanism includes at least two telescopic suction cup assemblies, which are respectively disposed on both sides of the opening of the packaging bag.

[0013] In one embodiment, the face mask isolation bag-feeding device further includes a discharge mechanism, which includes a sealing component, a first conveying component, a second conveying component, and a support pusher assembly.

The gripper assembly can rotate relative to the fixed plate assembly, adjusting the mask to the optimal bagging angle. Combined with the synchronous movement of the baffle, this ensures the mask smoothly enters the bag. The gripper assembly holds the mask's tubing connections, avoiding direct gripping of the airbag or sealed thin-walled areas, preventing deformation or damage. The baffle only serves an isolation function, with no relative friction to the airbag, thus protecting the integrity of the mask structure. The fixed plate assembly integrates gripper rotation, baffle sliding, lifting, and horizontal movement functions, working in conjunction with bag conveying, opening, and sealing stations, making production highly efficient and improving structural compactness, thereby achieving continuous automated production.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 As shown, this is a medical mask isolation bagging device 10 according to an embodiment of the present invention, including a workbench 100, a bag conveying mechanism 200, a mask conveying mechanism 300, a bag opening mechanism 400, and a bag feeding mechanism 500. The bag conveying mechanism 200 includes a bag conveying assembly 210 and a mounting bracket assembly 220. The bag conveying assembly 210 is installed on the workbench 100, and the mounting bracket assembly 220 is placed on the bag conveying assembly 210 and is used to hang the packaging bag. The mask conveying mechanism 300 is installed on the workbench 100 and is disposed opposite to the bag conveying mechanism 200. The mask conveying mechanism 300 is used to transfer masks. The bag opening mechanism 400 is disposed at the discharge end of the bag conveying mechanism 200 and is used to open the bag opening of the packaging bag. Further, the bag-feeding mechanism 500 includes a fixed plate assembly 510, a gripper assembly 520, a baffle plate 530, and a drive frame assembly 540. The drive frame assembly 540 is disposed at the discharge end of the mask conveying mechanism 300, and the fixed plate assembly 510 is slidably mounted on the drive frame assembly 540. The gripper assembly 520 is rotatably disposed on the fixed plate assembly 510 and is used to grip the pipe connection of the mask. The baffle plate 530 is slidably disposed on the fixed plate assembly 510 and is used to separate the mask from the packaging bag. The drive frame assembly 540 is used to drive the fixed plate assembly 510 to slide horizontally and move vertically, so as to drive the mask and the baffle plate 530 into the packaging bag.

[0024] In this embodiment, the bag conveying assembly 210 transports the mounting bracket assembly 220, which carries the packaging bag, to the bag opening station. The mask conveying mechanism 300 transports the mask to the bag insertion station. The bag opening mechanism 400 opens the bag opening, keeping it open. The drive frame assembly 540 moves the fixing plate assembly 510 and the gripper assembly 520 closer to the mask. The gripper assembly 520 clamps the tube connection of the mask. The drive frame assembly 540 moves the fixing plate assembly 510 to the mounting bracket assembly. Above 220, the fixing plate assembly 510 flips the gripper assembly 520 and the face mask so that the face mask is positioned above the opening of the packaging bag, with the air bladder of the face mask facing horizontally. The shield 530 slides along the fixing plate assembly 510 and extends from the initial position to cover the side of the air bladder of the face mask facing the inner wall of the bag opening. The drive frame assembly 540 drives the fixing plate assembly 510 to slide horizontally and descend, so that the face mask held by the gripper assembly 520, together with the extended shield 530, enters the interior of the open packaging bag. During the bagging process, the shield 530 is always positioned between the airbag and the bag wall to prevent the airbag from directly contacting the inner wall of the packaging bag, thereby eliminating bag sticking and jamming caused by the airbag sticking to the packaging tape. After the mask is completely inside the packaging bag, the gripper assembly 520 releases the mask, and the drive frame assembly 540 drives the fixing plate assembly 510 and the gripper assembly 520 to rise and exit the packaging bag. The shield 530 slides back to its original position along the fixing plate assembly 510, completing the isolation bagging action. The bag conveying mechanism 200 transfers the packaging bag containing the mask to the next process. The mask conveying mechanism 300 conveys the next mask to the bagging station.

[0025] The aforementioned medical mask isolation bagging device 10, by incorporating a retractable baffle 530 within the bagging mechanism 500, physically blocks contact between the airbag and the inner wall of the packaging bag throughout the entire process of the mask entering the bag. This prevents packaging abnormalities caused by the airbag of the mask sticking to the packaging bag, thereby improving the bagging qualification rate. The gripper assembly 520 can rotate relative to the fixing plate assembly 510 to adjust the mask to the optimal bagging angle. Combined with the synchronous movement of the baffle 530, this ensures the mask enters smoothly. The face mask enters the bag smoothly, and the gripper assembly 520 clamps the tube connection of the mask, avoiding direct clamping of the airbag or sealed thin-walled area to prevent deformation or damage. The shield 530 only serves as an isolation function and has no relative friction with the airbag, thus protecting the integrity of the mask structure. The fixing plate assembly 510 integrates the functions of gripper rotation, shield 530 sliding, lifting and horizontal movement, and works in conjunction with bag conveying, bag opening and sealing stations to make production operations efficient and improve the compactness of the structure, thereby realizing continuous automated production.

[0026] like Figure 5As shown, in one embodiment, the mask conveying mechanism 300 includes a mask conveying assembly 310 and a fixture assembly 320. The mask conveying assembly 310 is mounted on the worktable 100, and the fixture assembly 320 is placed on the mask conveying assembly 310. The fixture assembly 320 is used to install the mask. In this embodiment, the mask conveying assembly 310 is arranged on the worktable 100 along a preset direction. The mask conveying assembly 310 can be conveyed by a flat belt, synchronous belt, chain, or roller conveyor line. The fixture assembly 320 is used to install the mask. Multiple fixture assemblies 320 can be placed on the mask conveying assembly 310. When different specifications of masks need to be produced, the fixture assemblies 320 can be replaced for production, improving the flexibility of production changeover. When gripping, the gripper assembly 520 of the bagging mechanism 500 moves above or to the side of the fixture assembly 320 to accurately grip the tube connection of the mask and lift the mask, separating the mask from the fixture assembly 320.

[0027] like Figure 7 In one embodiment, the jig assembly 320 includes a jig base 321 and a support column 322. The support column 322 is fixed to the surface of the jig base 321 and has a receiving portion for receiving the face mask. The receiving portion forms a supporting surface, and the face mask is fitted onto the support column 322 and abuts against the supporting surface. In this embodiment, the face mask is horizontally limited by the cooperation of the opening with the support column 322, and vertically positioned by the supporting surface, ensuring accurate installation. The face mask rests on the supporting surface by gravity alone. When the gripper assembly 520 clamps the pipe connection and pulls upward, the opening of the face mask slides out along the axial direction of the support column 322, allowing the face mask to separate smoothly from the jig base 321.

[0028] like Figure 7 As shown, in one embodiment, the fixture assembly 320 further includes a positioning member 323 connected to the support column 322. The other end of the positioning member 323 has a limiting groove 3201, which engages with a protrusion on the face mask. In this embodiment, the positioning member 323 is fixed to the side wall or top of the support column 322 and extends radially outward or axially upward. The shape and size of the limiting groove 3201 match the protrusion on the face mask, constraining the rotation of the face mask along the axis of the support column 322, improving positioning accuracy, and ensuring that the gripper assembly 520 holds the face mask in a fixed position each time, thus improving the stability of the face mask packaging process.

[0029] like Figure 7As shown, further, in one embodiment, the mask conveying mechanism 300 also includes a hook feeding assembly 330. The hook feeding assembly 330 is disposed at the feeding end of the mask conveying assembly 310. The hook feeding assembly 330 includes a vibratory feeder discharging assembly 331 and a hook gripping assembly 332. The vibratory feeder discharging assembly 331 is used to convey hooks, and the hook gripping assembly 332 is used to move the hooks and fit them onto the support column 322. In this embodiment, the vibratory feeder discharging assembly 331 is provided with a discharging track to convey the hooks to the picking position in a uniform orientation. When the fixture assembly 320 is sent to the feeding position by the mask conveying assembly 310, the hook gripping assembly 332 grabs a hook from the picking position of the vibratory feeder discharging assembly 331, moves it to directly above the support column 322 of the fixture assembly 320, aligns the mounting hole of the hook with the top of the support column 322 and fits it in, so that the hook falls on the receiving part of the support column 322, allowing the mask to be stacked and assembled with the hook.

[0030] like Figure 7 As shown, in one embodiment, the mask conveying mechanism 300 further includes a hook assembly 340. The hook assembly 340 includes a clamping member 341 and a pushing member 342 respectively disposed on both sides of the mask conveying assembly 310. The clamping member 341 is provided with a positioning groove 3401 that matches the bottom of the mask tube connection portion. The pushing member 342 is used to push the hook. The clamping member 341 and the pushing member 342 cooperate to press the hook against the tube connection portion of the mask. In this embodiment, the clamping member 341 and the pushing member 342 can be driven by a cylinder or an electric cylinder. The hook assembly 340 is used to pre-fit the support column 322 so that the hook and the tube connection portion of the mask are pressed together. Through the clamping member 341 and the pushing member 342 disposed on both sides, the automatic pressing and assembly of the hook and the mask tube connection portion is realized, improving assembly consistency and efficiency.

[0031] As further shown in the figure, in one embodiment, the mask conveying assembly 310 includes a first conveyor belt 311, a second conveyor belt 312, a first separating lifting assembly 313, a second separating lifting assembly 314, a first movable push plate 315, and a second movable push plate 316. The first conveyor belt 311 and the second conveyor belt 312 are arranged parallel to each other on the workbench 100. The first separating lifting assembly 313 and the second separating lifting assembly 314 are disposed between the first conveyor belt 311 and the second conveyor belt 312. The first movable push plate 315 is used to move the fixture assembly 320 from the first conveyor belt 311 to the second conveyor belt 312, and the second movable push plate 316 is used to push the fixture assembly 320 from the second conveyor belt 312 back to the first conveyor belt 311. In this embodiment, the first separating lifting assembly 313 and the second separating lifting assembly 314 are respectively disposed at both ends between the first conveyor belt 311 and the second conveyor belt 312. Each separating lifting assembly includes a lifting cylinder and a separating plate 233. When raised, the lateral channel between the two conveyor belts is blocked, and when lowered, the channel is opened. When the first conveyor belt 311 conveys the jig assembly 320 from the feed end to the second moving push plate 316, the second separating lifting assembly 314 is lowered, and the second moving push plate 316 pushes the jig assembly 320 from the first conveyor belt 311 into the second conveyor belt 312. The second separating lifting assembly 314 is raised, and the jig assembly 320 is conveyed in the opposite direction from the second conveyor belt 312 to near the first moving push plate 315. After the face mask is clamped, the first separating lifting assembly 313 is lowered, and the first moving push plate 315 pushes the empty jig assembly 320 from the second conveyor belt 312 back to the first conveyor belt 311.

[0032] like Figure 4As shown, in one embodiment, the fixing plate assembly 510 includes a mounting fixing plate 511, a swing drive member 512, a rotating shaft connector 513, and a lifting frame assembly 514. The mounting fixing plate 511 is slidably disposed on the drive frame assembly 540, the lifting frame assembly 514 is connected to the mounting fixing plate 511, the shielding plate 530 is slidably disposed on the lifting frame assembly 514, the rotating shaft connector 513 is rotatably disposed on the mounting fixing plate 511, the gripper assembly 520 is rotatably connected to the rotating shaft connector 513, and the swing drive member 512 abuts against the rotating shaft connector 513 and is used to drive the rotating shaft connector 513 to rotate. In this embodiment, the drive frame assembly 540 drives the mounting plate 511 to move horizontally and vertically; the swing drive 512 drives the rotating shaft connector 513, causing the rotating shaft connector 513 to drive the gripper assembly 520 and the held mask to swing in a vertical or horizontal plane to adjust the mask's insertion angle; the shielding plate 530 is installed on the movable end of the lifting frame assembly 514, and the lifting frame assembly 514 drives the shielding plate 530 to rise and fall independently relative to the mounting plate 511, so that the shielding plate 530 covers the side of the mask's airbag facing the inner wall of the bag opening; the swinging motion of the gripper assembly 520 and the rising and falling motion of the shielding plate 530 are independent of each other and can be controlled in coordination, realizing mask angle adjustment and isolation protection, thereby improving the flexibility and reliability of the insertion action.

[0033] like Figure 4 As shown, the baffle 530 further includes a baffle body 531 and two side baffles 532. The baffle body 531 is slidably disposed on the lifting frame assembly 514, and the two side baffles 532 are respectively disposed on both sides of the baffle body 531. In this embodiment, the two side baffles 532 and the baffle body 531 form a semi-enclosed structure. When the baffle 530 extends downward with the lifting assembly, the baffle body 531 is located on the side of the face mask airbag facing the inner wall of the packaging bag, and the two side baffles 532 are respectively located on the left and right sides of the airbag, thereby forming a three-sided isolation barrier on the front and two sides of the airbag. This prevents the airbag from contacting and adhering to the side wall of the packaging bag due to slight deviation in posture during the bag insertion process, further improving the comprehensiveness of the isolation. In addition, the two side baffles 532 guide the face mask smoothly into the bag opening, avoiding scratching between the edge of the airbag and the edge of the bag opening, and improving the stability and reliability of the bag insertion action.

[0034] like Figure 4As shown, in one embodiment, the gripper assembly 520 includes a first gripper 521, a second gripper 522, and a drive cylinder 523. The drive cylinder 523 is connected to the fixing plate assembly 510 and is used to drive the first gripper 521 and the second gripper 522 to move relative to each other in order to grip or release the mask. In this embodiment, the contours of the first gripper 521 and the second gripper 522 are adapted to the outer edge of the tube connection of the face mask. The pneumatically driven cylinder 523 extends or retracts, causing the first gripper 521 and the second gripper 522 to move closer or further apart, thereby achieving clamping or releasing at the tube connection. By controlling the drive cylinder 523, the timing of the bag insertion action can be precisely matched, and the face mask can be released in time after entering the packaging bag, ensuring that the face mask remains in the bag and the grippers exit smoothly. Flexible pads can be provided on the clamping surfaces of the first gripper 521 and the second gripper 522 to increase friction and prevent scratching the surface of the face mask tube.

[0035] like Figure 11 As shown, in one embodiment, the mounting bracket assembly 220 includes a bracket base 221 and at least two opposing clamping assemblies 222. Each clamping assembly 222 includes a support arm 2221, a clamping member 2222, and an elastic member 2223. The elastic member 2223 abuts against the support arm 2221 and the clamping member 2222, respectively, and the elastic member 2223 is used to provide an elastic force to the clamping member 2222 that tends to press against the edge of the bag opening. In this embodiment, two clamping components 222 are mounted opposite each other on the upper surface or side of the support base 221, forming a clamping area for fixing the bag opening. The clamping member 2222 is movably mounted on the support arm 2221 and can slide or swing relative to the support arm 2221. Its end is provided with a pressure head for directly pressing the edge of the bag opening. The two ends of the elastic member 2223 abut against the support arm 2221 and the clamping member 2222 respectively, always applying a pressure to the clamping member 2222. The two clamping components 222 are positioned opposite each other and apply an elastic bias force to the clamping components 2222. When the clamping components 2222 are pushed, the elastic component 2223 is compressed, causing the pressure head of the clamping components 2222 to separate from the support arm 2221. After the push force is released, the elastic component 2223 drives the clamping components 2222 to press the packaging bag together. The two clamping components 222 are arranged opposite each other and jointly clamp the two sides or two suspension points of the bag opening, so that the bag opening is kept flat and open in a ready state, which is convenient for the subsequent bag opening mechanism 400 to fully open the bag opening.

[0036] like Figure 9As shown, in one embodiment, the medical mask isolation bagging device 10 further includes a feeding mechanism 600, which includes a placement platform 610 and a bag-picking assembly 620. The placement platform 610 is installed on the workbench 100. The bag-picking assembly 620 includes a bag-picking drive assembly 621, a swing arm 622, and a bag-clamping assembly 623 disposed on the work cover 100. The swing arm 622 is rotatably disposed at the output end of the bag-picking drive assembly 621. The bag-clamping assembly 623 is installed on the swing arm 622 and is disposed adjacent to the feeding end of the bag conveying assembly 210. In this embodiment, the bag clamping assembly 623 is used to clamp the end of the package. The bag taking drive assembly 621 drives the swing arm 622 to rotate, causing the package bag clamped by the clamping assembly 222 to flip from a horizontal state to a vertical hanging state, so that the package bag can be hung on the bag body support assembly. The bag opening is located above or towards the clamping assembly 222 of the bag body support assembly.

[0037] like Figure 10 As shown, the feeding mechanism 600 further includes a bracket opening and clamping assembly 630, which includes an opening and clamping fixing plate 631, an opening and clamping cylinder 632, and an opening and clamping push plate 633. The opening and clamping fixing plate 631 is fixed to the workbench 100 and is located at the feeding end of the bag conveying assembly 210. The two opening and clamping cylinders 632 are correspondingly installed on both sides of the opening and clamping fixing plate 631. Each opening and clamping push plate 633 is installed on the corresponding opening and clamping cylinder 632, and each opening and clamping push plate 633 is used to push the corresponding hanging bracket assembly 220 to release the packaging bag. In this embodiment, when an empty bag support assembly is delivered to the feeding station by the feeding pusher assembly 235 or the return conveyor belt 231, the two opening cylinders 632 operate simultaneously, pushing the opening pusher plate 633 to extend and respectively abut against and push the clamping member 2222 of the corresponding clamping assembly 222. This overcomes the elastic force of the elastic member 2223, causing the clamping member 2222 to open. The bag taking assembly 620 then feeds the edge of the flipped packaging bag opening between the open clamping assemblies 222. Subsequently, the opening cylinders 632 retract, the opening pusher plate 633 disengages from the clamping assembly 222, and the clamping assembly 222 automatically resets under the action of the elastic member 2223, pressing the edge of the packaging bag opening, thereby completing the automatic bag loading.

[0038] like Figure 8As shown, the feeding mechanism 600 further includes a bag printing component 640 and a bag shaping component 650 sequentially arranged on the worktable 100. The printing component is used to print on the packaging bag, and the shaping component is used to press the packaging bag to flatten it. The placement platform 610 is arranged on one side of the bag shaping component 650. In this embodiment, by sequentially arranging the bag printing component 640, the bag shaping component 650, and the placement platform 610 and moving them through the suction cup component, online marking and flattening of the packaging bag are achieved, avoiding problems such as suction cup leakage and bag opening failure caused by bag wrinkles, thus improving the bag opening success rate.

[0039] like Figure 2 As shown, in one embodiment, the bag opening mechanism 400 includes at least two telescopic suction cup assemblies 410, which are respectively disposed on both sides of the bag opening of the packaging bag. In this embodiment, the two telescopic suction cup assemblies 410 are located on both sides of the bag opening. When the mounting bracket assembly 220 carries the packaging bag to the bag opening station, the two telescopic suction cup assemblies 410 simultaneously extend towards the bag opening to suction the two sides of the bag opening. The two telescopic suction cup assemblies 410 retract to smoothly pull the bag opening open to the open state, realizing uniform stretching of the bag opening and avoiding bag opening skewing or tearing caused by unilateral force, thus improving the bag opening success rate.

[0040] like Figure 2 As shown, further, in one embodiment, each of the telescopic suction cup assemblies 410 includes a suction cup base 411, a vacuum suction component 412, and a telescopic drive component 413. Two telescopic drive components 413 are positioned opposite each other on both sides of the packaging bag with an opening mechanism. Each vacuum suction cup component is installed at the movable end of the corresponding telescopic drive component 413, and each vacuum suction cup component is connected to an external air source. In this embodiment, the vacuum suction component 412 is fixed to the movable end of the telescopic drive component 413 and connected to an external vacuum generator or vacuum source via an air pipe. When the packaging bag is positioned, both telescopic drive components 413 extend simultaneously, causing the vacuum suction component 412 to press against both sides of the bag opening. The external air source draws air, creating a negative pressure inside the suction cup, firmly adhering to the bag wall. The telescopic drive component 413 retracts, causing the adsorbed bag wall to separate to both sides, completing the bag opening.

[0041] like Figure 2As shown, further, there are multiple vacuum suction components 412, and the movable end of the telescopic drive component 413 is provided with a sliding groove 4101. Two vacuum suction components 412 are arranged adjacent to each other on both sides of the movable groove. In this embodiment, the vacuum suction components 412 are installed in the sliding groove 4101 by locking nuts or positioning bolts, and the distance between them can be adjusted within the sliding groove 4101 to adapt to packaging bags of different widths or different opening positions. The two suction cups act on two different points at the bag opening, making the force on the bag opening more even when it is pulled open, reducing the phenomenon of wrinkling or partial incomplete opening of the bag opening, and enhancing the stability and reliability of opening the bag.

[0042] like Figure 1 and Figure 12 As shown, in one embodiment, the medical mask isolation bag-insertion device 10 further includes a discharge mechanism 700, which includes a sealing component 710, a first conveying component 720, a second conveying component 730, and a support pusher plate component 740. The first conveying component 720 is disposed at the discharge end of the bag conveying component 210 and is used to convey the mounting support component 220. The second conveying component 730 is disposed below the packaging bag and is used to convey the sealed packaging bag. The support pusher plate component 740 is disposed on one side of the first conveying component 720 and is used to drive the mounting support component 220 to release the packaging bag. In this embodiment, after the face mask is placed into the bag, the packaging bag containing the face mask, along with the mounting bracket assembly 220, is transferred from the bag conveying assembly 210 to the discharge end and then transitions to the first conveying assembly 720. The first conveying assembly 720 carries the mounting bracket assembly 220 and conveys it to the sealing assembly 710. When the mounting bracket assembly 220 passes the sealing assembly 710, the sealing assembly 710 heat-seals the opening of the packaging bag. After sealing, the bracket pusher assembly 740, located on one side of the first conveying assembly 720, extends out to drive the bag. When the clamping component 222 on the movable mounting bracket assembly 220 is pushed, the clamping member 2222 of the clamping component 222 compresses the elastic member 2223 of the clamping component 222, causing the pressure head of the clamping member 2222 of the clamping component 2222 to separate from the support arm 2221, thereby releasing the packaging bag containing the mask. The packaging bag falls to the second conveying component 730 below and is conveyed to the next process. The empty mounting bracket assembly 220 continues to move forward with the first conveying component 720 and flows back to the upper bag station or is manually recycled.

[0043] like Figure 10 and Figure 13As shown, in one embodiment, the bag conveying mechanism 200 further includes a return conveying assembly 230, which includes a return conveyor belt 231, a discharge pusher assembly 232, a partition plate 233, a lifting plate drive 234, and a feeding pusher assembly 235. The partition plate 233 is disposed between the return conveyor belt 231 and the first conveying assembly 720. The lifting plate drive 234 is used to drive the partition plate 233 to rise and fall. The discharge pusher assembly 232 is disposed on one side of the first conveying assembly 720, and the feeding pusher assembly 235 is disposed at the feeding end of the bag conveying assembly 210. In this embodiment, the return conveyor belt 231 is arranged parallel to and in opposite directions to the first conveying assembly 720. The conveying direction of the return conveyor belt 231 is opposite to that of the first conveying assembly 720, and it is used to convey the empty hanging bracket assembly 220 after the packaging bag is released from the discharge end back to the feed end. A partition is arranged between the return conveyor belt 231 and the first conveying assembly 720 to separate them in space and prevent the hanging bracket assembly 220 from colliding, falling or shifting during the conveying process. The lifting plate drive 234 is connected to the partition plate 233. The partition plate 233 is used to drive the lifting and lowering of the partition plate 233. When the empty hanging bracket assembly 220 is transferred from the first conveying assembly 720 to the return conveyor belt 231, the lifting plate drive component 234 drives the partition plate 233 to descend, opening the channel between the two belts. The discharge push plate assembly 232, located on one side of the first conveying assembly 720, extends and pushes the empty bracket assembly located at the end of the first conveying assembly 720 laterally onto the return conveyor belt 231. The partition plate 233 rises and resets, and the return conveyor belt 231 transports the empty bracket assembly in the opposite direction to the feeding end. When the empty hanging bracket assembly 220 reaches the feeding end, the feeding push plate assembly 235, located at the feeding end of the bag conveying assembly 210, extends and pushes the empty hanging bracket assembly 220 back from the return conveyor belt 231 to the bag mounting station for re-hanging packaging bags and entering the next cycle.

[0044] like Figure 12As shown, in one embodiment, the packaging component 710 includes a first packaging block 711, a second packaging block 712, a packaging driver 713, and a packaging frame 714. The packaging frame 714 is mounted on the workbench 100, and the packaging driver 713 is mounted on the packaging frame 714 and drives the first packaging block 711 and the second packaging block 712 to open and close. In this embodiment, the packaging frame 714 is fixed on the workbench 100 as an overall support for the packaging assembly 710. The packaging drive 713 is installed on the packaging frame 714. The piston rod of the packaging drive 713 is connected to the first packaging block 711 and the second packaging block 712 through a connecting rod, gear rack or slider mechanism. When the packaging drive 713 moves, the first packaging block 711 and the second packaging block 712 can move closer or further away from each other synchronously. The first packaging block 711 and the second packaging block 712 are equipped with heating modules. When the packaged bag is transported to the packaging station by the bag support assembly, the drive cylinder 523 pushes the first packaging block 711 and the second packaging block 712 closer to each other to press the bag opening with a set pressure. At the same time, the heating module is activated to heat and fuse or ultrasonically fuse the packaging bag opening to complete the sealing.

[0045] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned medical mask isolation bagging device 10, by incorporating a retractable baffle 530 within the bagging mechanism 500, physically blocks contact between the airbag and the inner wall of the packaging bag throughout the entire process of the mask entering the bag. This prevents packaging abnormalities caused by the airbag of the mask sticking to the packaging bag, thereby improving the bagging qualification rate. The gripper assembly 520 can rotate relative to the fixing plate assembly 510 to adjust the mask to the optimal bagging angle. Combined with the synchronous movement of the baffle 530, this ensures the mask enters smoothly. The face mask enters the bag smoothly, and the gripper assembly 520 clamps the tube connection of the mask, avoiding direct clamping of the airbag or sealed thin-walled area to prevent deformation or damage. The shield 530 only serves as an isolation function and has no relative friction with the airbag, thus protecting the integrity of the mask structure. The fixing plate assembly 510 integrates the functions of gripper rotation, shield 530 sliding, lifting and horizontal movement, and works in conjunction with bag conveying, bag opening and sealing stations to make production operations efficient and improve the compactness of the structure, thereby realizing continuous automated production.

[0046] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
