[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0029] See also Figure 1 and Figure 2The embodiment of the present application provides a bag support mechanism 100, which can support the bag opening 501 of the packaging bag 500, so that the material can be easily loaded into the packaging bag 500, shortening the time of loading the material into the packaging bag 500, improving production efficiency, and also helping to achieve automation. The present application takes a blood bag as an example for explanation.

[0030] The bag holding mechanism 100 includes a first bag holding component 10, a second bag holding component 30 and a driving assembly 50. The first bag holding component 10 and the second bag holding component 30 can be installed on the driving assembly 50. The driving assembly 50 can drive the first bag holding component 10 and the second bag holding component 30 to move. For example, it can drive the first bag holding component 10 and the second bag holding component 30 to selectively approach or move away from each other, and can also drive the first bag holding component 10 and the second bag holding component 30 to selectively extend into or extend out of the packaging bag 500, so that the first bag holding component 10 and the second bag holding component 30 can support, pull, etc. the bag opening 501 of the packaging bag 500.

[0031] See also Figure 2 and Figure 3 The first bag-supporting member 10 includes a first bag-opening supporting portion 11 and a first bag-opening pulling portion 13, which are connected to each other. The first bag-opening supporting portion 11 is suitable for supporting the bag-opening 501 of the packaging bag 500, and the first bag-opening pulling portion 13 is suitable for leveling the bag-opening 501 of the packaging bag 500. The first bag-opening supporting portion 11 can be a sheet metal part or a casting part.

[0032] The first bag opening support part 11 may include a first bag opening support plate 111 and a second bag opening support plate 113. The first bag opening support plate 111 and the second bag opening support plate 113 may extend into the packaging bag 500 under the drive of the driving assembly 50 to support the bag opening 501 of the packaging bag 500. The first bag opening support plate 111 and the second bag opening support plate 113 are connected. For example, the second bag opening support plate 113 and the first bag opening support plate 111 may be connected at an angle. The second bag opening support plate 113 may be inclined relative to the first bag opening support plate 111 toward the direction of the second bag supporting member 30, so that after the first bag opening support plate 111 and the second bag opening support plate 113 jointly support the bag opening 501 of the packaging bag 500, the bag opening 501 of the packaging bag 500 is unfolded in a shape more suitable for loading materials.

[0033] The first bag opening support plate 111 may include a first bag opening support body 1111 and a first curved body 1113. The first bag opening support body 1111 is connected to the first curved body 1113. For example, the first curved body 1113 may be connected to the edge of the first bag opening support body 1111 that is away from the second bag opening support plate 113. In this way, the first curved body 1113 helps to prevent the edge of the first bag opening support body 1111 that is away from the second bag opening support plate 113 from directly contacting the packaging bag 500 and thereby puncturing the packaging bag 500 or causing obvious scratches on the packaging bag 500.

[0034] The first curved arc 1113 can be located on the side of the first bag opening support body 1111 away from the second bag supporting member 30, thereby helping to avoid occupying the spatial position on the side of the first bag opening support body 1111 facing the second bag supporting member 30. In this way, in the process of subsequent material entering the packaging bag 500 from the gap between the first bag supporting member 10 and the second bag supporting member 30, obstruction to the process of material entering the bag is avoided.

[0035] The second bag opening support plate 113 may include a second bag opening support body 1131 and a second curved body 1133, and the second bag opening support body 1131 and the second curved body 1133 are connected. For example, the second curved body 1133 may be connected to the edge of the second bag opening support body 1131 that is away from the first bag opening support plate 111. In this way, the second curved body 1133 helps to prevent the edge of the second bag opening support body 1131 that is away from the first bag opening support plate 111 from directly contacting the packaging bag 500 and puncturing the packaging bag 500 or causing obvious scratches on the packaging bag 500.

[0036] The second curved arc body 1133 can be located on the side of the second bag opening support body 1131 away from the second bag supporting member 30, thereby helping to avoid occupying the spatial position on the side of the second bag opening support body 1131 facing the second bag supporting member 30. In this way, in the process of subsequent material entering the packaging bag 500 from the gap between the first bag supporting member 10 and the second bag supporting member 30, obstruction to the process of material entering the bag is avoided.

[0037] The first bag opening pulling portion 13 can be extended into the packaging bag 500 under the drive of the driving assembly 50 to level the bag opening 501 of the packaging bag 500. The first bag opening pulling portion 13 can be connected to the first bag opening supporting portion 11, for example, the first bag opening pulling portion 13 can be connected to the first bag opening supporting plate 111. The first bag opening pulling portion 13 can be in the shape of an elongated strip, and the first bag opening pulling portion 13 can extend in a direction away from the first bag opening supporting portion 11. Since the second bag opening supporting plate 113 is inclined relative to the first bag opening supporting plate 111 toward the direction of the second bag supporting member 30, the first bag opening pulling portion 13 connected to the first bag opening supporting plate 111 is more helpful in leveling the bag opening 501 of the packaging bag 500 than connecting to the second bag opening supporting plate 113.

[0038] The second bag-supporting member 30 includes a second bag-opening supporting portion 31 and a second bag-opening pulling portion 33, which are connected to each other, and the second bag-opening supporting portion 31 is suitable for supporting the bag-opening 501 of the packaging bag 500, and the second bag-opening pulling portion 33 is suitable for leveling the bag-opening 501 of the packaging bag 500. The second bag-opening supporting portion 31 can be a sheet metal part or a casting part.

[0039] The second bag opening support part 31 may include a third bag opening support plate 311 and a fourth bag opening support plate 313. The third bag opening support plate 311 and the fourth bag opening support plate 313 may extend into the packaging bag 500 under the drive of the driving assembly 50 to support the bag opening 501 of the packaging bag 500. The third bag opening support plate 311 and the fourth bag opening support plate 313 are connected, for example, the fourth bag opening support plate 313 and the third bag opening support plate 311 may be connected at an angle, and the fourth bag opening support plate 313 may be inclined relative to the third bag opening support plate 311 toward the direction of the first bag supporting member 10, so that after the third bag opening support plate 311 and the fourth bag opening support plate 313 jointly support the bag opening 501 of the packaging bag 500, the shape of the bag opening 501 of the packaging bag 500 is more suitable for loading materials.

[0040] The third bag opening support plate 311 may include a third bag opening support body 3111 and a third curved body 3113. The third bag opening support body 3111 is connected to the third curved body 3113. For example, the third curved body 3113 may be connected to the edge of the third bag opening support body 3111 that is away from the fourth bag opening support plate 313. In this way, the third curved body 3113 helps to prevent the edge of the third bag opening support body 3111 that is away from the fourth bag opening support plate 313 from directly contacting the packaging bag 500 and thereby puncturing the packaging bag 500 or causing obvious scratches on the packaging bag 500.

[0041] The third curved arc 3113 can be located on the side of the third bag opening supporting body 3111 away from the first bag supporting member 10, thereby helping to avoid occupying the spatial position of the third bag opening supporting body 3111 on the side facing the first bag supporting member 10. In this way, in the process of subsequent material entering the packaging bag 500 from the gap between the first bag supporting member 10 and the second bag supporting member 30, obstruction to the process of material entering the bag is avoided.

[0042] The fourth bag opening support plate 313 may include a fourth bag opening support body 3131 and a fourth curved body 3133, and the fourth bag opening support body 3131 and the fourth curved body 3133 are connected. For example, the fourth curved body 3133 may be connected to the edge of the fourth bag opening support body 3131 that is away from the third bag opening support plate 311. In this way, the fourth curved body 3133 helps to prevent the edge of the fourth bag opening support body 3131 that is away from the third bag opening support plate 311 from directly contacting the packaging bag 500 and puncturing the packaging bag 500 or causing obvious scratches on the packaging bag 500.

[0043] The fourth curved arc 3133 can be located on the side of the fourth bag opening support body 3131 away from the first bag supporting member 10, thereby helping to avoid occupying the spatial position on the side of the fourth bag opening support body 3131 facing the first bag supporting member 10. In this way, in the process of subsequent material entering the packaging bag 500 from the gap between the first bag supporting member 10 and the second bag supporting member 30, obstruction to the process of material entering the bag is avoided.

[0044] The second bag opening pulling portion 33 can be extended into the packaging bag 500 under the drive of the driving assembly 50 to level the bag opening 501 of the packaging bag 500. The second bag opening pulling portion 33 can be connected to the second bag opening supporting portion 31, for example, the second bag opening pulling portion 33 can be connected to the third bag opening supporting plate 311. The second bag opening pulling portion 33 can be in the shape of an elongated strip, and the second bag opening pulling portion 33 can extend in a direction away from the second bag opening supporting portion 31. Since the fourth bag opening supporting plate 313 is inclined relative to the third bag opening supporting plate 311 toward the direction of the first bag supporting member 10, the second bag opening pulling portion 33 connecting to the third bag opening supporting plate 311 is more conducive to leveling the bag opening 501 of the packaging bag 500 than connecting to the fourth bag opening supporting plate 313.

[0045] Since the driving component 50 can drive the first bag holding component 10 and the second bag holding component 30 to selectively move closer to or farther from each other, after the bag opening 501 of the packaging bag 500 is opened, the driving component 50 can drive the first bag holding component 10 and the second bag holding component 30 to move closer to each other, so that the arrangement between the first bag holding component 10 and the second bag holding component 30 is more compact, which helps the subsequent driving component 50 to more easily drive the first bag holding component 10 and the second bag holding component 30 to extend into the packaging bag 500 from the bag opening 501 of the packaging bag 500.

[0046] In addition, after the first bag supporting member 10 and the second bag supporting member 30 are located in the packaging bag 500, the driving assembly 50 can drive the first bag supporting member 10 and the second bag supporting member 30 located in the packaging bag 500 to move away from each other, so that the first bag opening supporting portion 11 of the first bag supporting member 10 and the second bag opening supporting portion 31 of the second bag supporting member 30 support the bag opening 501 of the packaging bag 500, thereby preventing the packaging bag 500 from being unable to stably maintain an unfolded shape due to its soft texture; and since the first bag supporting member 10 and the second bag supporting member 30 are away from each other, the distance between the first bag supporting member 10 and the second bag supporting member 30 is larger, which helps the material to enter the packaging bag 500 from the distance between the first bag supporting member 10 and the second bag supporting member 30, thereby reducing the impact of obstruction on the process of material entering the bag.

[0047] Since the driving assembly 50 can also drive the first bag supporting member 10 and the second bag supporting member 30 to selectively extend into or out of the packaging bag 500, in this process, the driving assembly 50 can drive the first bag supporting member 10 and the second bag supporting member 30 to move to different positions. The positions may include a bag opening support position, a bag opening pulling position and a packaging bag separation position. The bag opening pulling position may be located between the packaging bag separation position and the bag opening support position. The direction from the packaging bag separation position to the bag opening support position may be the direction from the first bag opening support portion 11 to the first bag opening pulling portion 13, or the direction from the packaging bag separation position to the bag opening support position may be the direction from the second bag opening support portion 31 to the second bag opening pulling portion 33.

[0048] When the driving assembly 50 drives the first bag supporting member 10 and the second bag supporting member 30 to move from the packaging bag separation position to the bag opening supporting position, the first bag supporting member 10 and the second bag opening supporting member 30 extend into the packaging bag 500, and the first bag opening supporting portion 11 and the second bag opening supporting portion 31 can support the bag opening 501 of the packaging bag 500. At this time, the bag opening 501 of the packaging bag 500 is stably maintained in an expanded shape, and the material can be more easily loaded into the packaging bag 500.

[0049] After the material is loaded into the packaging bag 500, the driving assembly 50 can also drive the first bag-supporting member 10 and the second bag-supporting member 30 to move from the bag-opening supporting position to the bag-opening pulling position. In this process, the driving assembly 50 can drive the first bag-opening supporting portion 11 of the first bag-supporting member 10 and the second bag-opening supporting portion 31 of the second bag-supporting member 30 to exit the packaging bag 500, and keep the first bag-opening pulling portion 13 and the second bag-opening pulling portion 33 in the packaging bag 500, so that the first bag-opening pulling portion 13 and the second bag-opening pulling portion 33 can level the bag-opening 501 of the packaging bag 500.

[0050] In addition, the position may also include a bag opening heat-sealing position, and the bag opening heat-sealing position may be located between the bag opening supporting position and the bag opening pulling position. After the first bag supporting member 10 and the second bag supporting member 30 support the bag opening 501 of the packaging bag 500, and before the first bag supporting member 10 and the second bag supporting member 30 move to the bag opening pulling position, the driving assembly 50 may also drive the first bag supporting member 10 and the second bag supporting member 30 to move from the bag opening supporting position to the bag opening heat-sealing position.

[0051] In the process of the first bag supporting member 10 and the second bag supporting member 30 moving to the bag opening heat-sealing position, since the first bag opening supporting portion 11 and the second bag opening supporting portion 31 are always located in the packaging bag 500, the contact area between the first bag opening supporting portion 11, the second bag opening supporting portion 31 and the packaging bag 500 is relatively large, so that the friction between the bag supporting mechanism 100 and the packaging bag 500 is also relatively large. Under the action of the friction force, the first bag supporting member 10 and the second bag supporting member 30 moving from the bag opening supporting position to the bag opening heat-sealing position can drive the packaging bag 500 to move, thereby facilitating the first bag opening pulling portion 13 and the second bag opening pulling portion 33 to flatten the bag opening 501 of the packaging bag 500, and the hot melt machine heat-seals the bag opening 501 of the packaging bag 500, and helps to prevent the bag opening 501 of the packaging bag 500 from being wrinkled after the heat-seal.

[0052] like Figure 2 As shown, in order to realize that the driving assembly 50 drives the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to each other, farther from each other, and to positions such as the bag opening support position, the bag opening heat-sealing position, the bag opening pulling position, and the packaging bag separation position, the driving assembly 50 may include a first driving assembly 51 and a second driving assembly 53. The first bag-supporting member 10 and the second bag-supporting member 30 may be installed on the first driving assembly 51, and the first driving assembly 51 may drive the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to each other, farther from each other, and the like. The first driving assembly 51 may be installed on the second driving assembly 53, and the second driving assembly 53 may drive the first driving assembly 51 to move, so that the first bag-supporting member 10 and the second bag-supporting member 30 may move to positions such as the bag opening support position, the bag opening heat-sealing position, the bag opening pulling position, and the packaging bag separation position.

[0053] The first driving assembly 51 may include a first bracket 511, a first guide rail pair 513, and a first driving module 515. The first bracket 511 may be mounted on the second driving assembly 53, and the first guide rail pair 513 and the first driving module 515 may be mounted on the first bracket 511. The first bracket 511 may serve as a base of the first driving assembly 51 and is used to carry structures such as the first guide rail pair 513 and the first driving module 515. The first bracket 511 may also serve as a connecting piece of the first driving assembly 51 to facilitate connection and combination with other structures.

[0054] The first guide rail pair 513 may be a universal part to simplify the manufacturing difficulty and manufacturing cost of the first guide rail pair 513. The support rail of the first guide rail pair 513 may be fixedly connected to the first bracket 511 by fasteners such as screws and bolts. The first bag-supporting member 10 and the second bag-supporting member 30 may be respectively connected to two different sliders 5131 of the first guide rail pair 513. For example, the first bag-supporting member 10 may be fixedly connected to the slider 5131 of the first guide rail pair 513 by fasteners such as screws and bolts, and the second bag-supporting member 30 may be connected to the other slider 5131 of the first guide rail pair 513 by the same connection method.

[0055] The first driving module 515 can be connected to the first bag supporting member 10 and the second bag supporting member 30 respectively, so that the first driving module 515 can drive the first bag supporting member 10 and the second bag supporting member 30 to slide on the first guide rail pair 513. The first driving module 515 may include a driving motor, a main synchronous wheel, a slave synchronous wheel and a synchronous belt, and the driving motor and the slave synchronous wheel can be installed on the first bracket 511. The body of the driving motor can be fixedly connected to the first bracket 511 by fasteners such as bolts and screws, and the output shaft of the driving motor can be fixedly connected to the main synchronous wheel. The slave synchronous wheel is rotatably installed on the first bracket 511. The synchronous belt is sleeved on the main synchronous wheel and the slave synchronous wheel, so that the driving motor can drive the synchronous belt transmission to achieve the belt transmission effect. The synchronous belt can be connected to the first bag-supporting member 10 and the second bag-supporting member 30 respectively. For example, the first bag-supporting member 10 can be fixedly connected to the synchronous belt by buckling or other structures, and the second bag-supporting member 30 can also be fixed to the synchronous belt by the same connection method. In this way, under the drive of the driving motor, the synchronous belt can simultaneously drive the first bag-supporting member 10 and the second bag-supporting member 30 to move. The first driving module 515 uses the synchronous belt to drive the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to or away from each other, and the movement method is simple and efficient.

[0056] In addition, the bag-holding mechanism 100 may also be provided with a corresponding limit structure to control the limit position of the first bag-holding member 10 and the second bag-holding member 30 moving toward or away from each other. For example, the bag-holding mechanism 100 may also include a first detection sensor 71 and a second detection sensor 73. Since the first bag-holding member 10 and the second bag-holding member 30 move synchronously or stop moving, the first detection sensor 71 and the second detection sensor 73 may be located at intervals in the moving path of the first bag-holding member 10 or the second bag-holding member 30. In this embodiment, the first detection sensor 71 and the second detection sensor 73 are located at intervals in the moving path of the second bag-holding member 30.

[0057] The controller (not shown) of the bag-holding mechanism 100 can be electrically connected to the first driving module 515, the first detection sensor 71, and the second detection sensor 73, respectively, and control the first driving module 515 according to the detection signals of the first detection sensor 71 and the second detection sensor 73. For example, when the second bag-holding member 30 passes the first detection sensor 71, the controller can receive the detection signal of the first detection sensor 71 and control the first driving module 515 to stop moving, so that the first bag-holding member 10 and the second bag-holding member 30 stop moving toward each other. For another example, when the second bag-holding member 30 passes the second detection sensor 73, the controller can receive the detection signal of the second detection sensor 73 and control the first driving module 515 to stop moving, so that the first bag-holding member 10 and the second bag-holding member 30 stop moving away from each other. Among them, the controller can be a circuit board, the first detection sensor 71 and the second detection sensor 73 can both be groove-type photoelectric sensors, and the bag-holding mechanism 100 can include a baffle 90 that cooperates with the groove-type photoelectric sensor. The baffle 90 moves with the movement of the first bag-holding component 10 or the second bag-holding component 30. The sensing groove of the groove-type photoelectric sensor is located on the moving trajectory of the baffle 90. When the baffle 90 moves to a certain position, at least part of it enters the sensing groove, and then the corresponding detection sensor can generate a detection signal.

[0058] The second driving assembly 53 may include a second bracket 531 , a second guide rail pair 533 , and a second driving module 535 . The second guide rail pair 533 and the second driving module 535 may be installed on the second bracket 531 .

[0059] The second bracket 531 can serve as the base of the second drive component 53 and is used to support the first drive component 51, the second guide rail pair 533, the second drive module 535 and other structures. The second bracket 531 can also serve as a connecting piece of the second drive component 53 to facilitate connection and combination with other structures.

[0060] The second guide rail pair 533 may be made of universal parts to simplify the manufacturing difficulty and manufacturing cost of the second guide rail pair 533. The support rail of the second guide rail pair 533 may be fixedly connected to the second bracket 531 by fasteners such as screws and bolts. The slider of the second guide rail pair 533 may be connected to the first bracket 511, for example, the first bracket 511 may be fixedly connected to the slider of the second guide rail pair 533 by fasteners such as screws and bolts.

[0061] The second drive module 535 can be connected to the first bracket 511 to enable the first drive assembly 51 to slide on the second guide rail pair 533. The second drive assembly 53 can use universal parts to simplify the design difficulty of the second drive assembly 53 and reduce the manufacturing cost. For example, the second drive assembly 53 can be an electric cylinder.

[0062] During the use of the bag-opening mechanism 100, when the bag opening 501 of the packaging bag 500 is opened, Figure 1 As shown; the first driving component 51 of the driving component 50 can first drive the first bag supporting member 10 and the second bag supporting member 30 to approach each other, and then the second driving component 53 of the driving component 50 can drive the first bag supporting member 10 and the second bag supporting member 30 to move to the bag opening supporting position, and then the first driving component 51 can drive the first bag supporting member 10 and the second bag supporting member 30 to move away from each other to expand and support the bag opening 501 of the packaging bag 500, so as to facilitate the subsequent loading of materials, such as Figure 4 shown.

[0063] After the first bag-supporting member 10 and the second bag-supporting member 30 support the bag opening 501 of the packaging bag 500, the second driving component 53 can drive the first bag-supporting member 10 and the second bag-supporting member 30 to move from the bag opening supporting position to the bag opening heat-sealing position. After the first bag-supporting member 10 and the second bag-supporting member 30 move to the bag opening heat-sealing position, the first driving component 51 can first drive the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to each other to loosen the bag opening 501 of the packaging bag 500, and then the second driving component 53 can drive the first bag-supporting member 10 and the second bag-supporting member 30 to move from the bag opening heat-sealing position to the bag opening pulling position. After the first bag-supporting member 10 and the second bag-supporting member 30 move to the bag opening pulling position, the first driving component 51 can also drive the first bag-supporting member 10 and the second bag-supporting member 30 to move away from each other, so that the bag opening 501 of the packaging bag 500 can be better leveled, such as Figure 5 shown.

[0064] After the bag opening 501 of the packaging bag 500 is leveled, the bag opening 501 of the packaging bag 500 can be heat-sealed by a heat-sealing machine. After the bag opening 501 of the packaging bag 500 is heat-sealed, the first driving component 51 can drive the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to each other to loosen the bag opening 501 of the packaging bag 500, and then the second driving component 53 drives the first bag-supporting member 10 and the second bag-supporting member 30 to move from the bag opening pulling position to the packaging bag separation position so as to be separated from the packaging bag 500 containing the material.

[0065] like Figure 1 Shown and Figure 3 The embodiment of the present application also provides a bag opening device 300, which includes a packaging bag opening mechanism 700 and a bag supporting mechanism 100 of any of the above-mentioned embodiments. The direction from the bag supporting mechanism 100 to the packaging bag opening mechanism 700 is the direction from the first bag opening supporting portion 11 to the first bag opening pulling portion 13.

[0066] The packaging bag opening mechanism 700 can open the bag opening 501 of the packaging bag 500, which helps the bag-supporting mechanism 100 in subsequent operations to support and pull the bag opening 501 of the packaging bag 500. For example, the packaging bag opening mechanism 700 can include a suction cup assembly 701, which can suck the upper and lower surfaces of the packaging bag 500 and then pull to open the bag opening 501 of the packaging bag 500.

[0067] The suction cup assembly 701 may include a first suction cup and a second suction cup, the first suction cup and the second suction cup are arranged opposite to each other, and the two can be close to or away from each other. The packaging bag 500 can be located between the first suction cup and the second suction cup. When it is necessary to open the bag opening 501 of the packaging bag 500, the first suction cup and the second suction cup can be close to each other, so that the first suction cup can suck the lower surface of the packaging bag 500, and the second suction cup can suck the upper surface of the packaging bag 500, and then the first suction cup and the second suction cup can be away from each other, so that the bag opening 501 of the packaging bag 500 can be opened.

[0068] In the bag opening device 300 provided in the embodiment of the present application, the driving component 50 can drive the first bag-opening component 10 and the second bag-opening component 30 to move. For example, after the bag mouth 501 of the packaging bag 500 is opened, the driving component 50 can drive the first bag-opening component 10 and the second bag-opening component 30 to move closer to each other, so that the arrangement between the first bag-opening component 10 and the second bag-opening component 30 is more compact, which helps the subsequent driving component 50 to easily drive the first bag-opening component 10 and the second bag-opening component 30 to extend into the packaging bag 500; the driving component 50 can also drive the first bag-opening component 10 located in the packaging bag 500 to move closer to each other. The bag component 10 and the second bag supporting component 30 are far away from each other, so that the first bag opening supporting portion 11 and the second bag opening supporting portion 31 support the bag opening 501 of the packaging bag 500, thereby preventing the packaging bag 500 from being unable to stably maintain an expanded shape due to its soft texture; and because the first bag supporting component 10 and the second bag supporting component 30 are far away from each other, the distance between the first bag supporting component 10 and the second bag supporting component 30 is larger, which helps the material to enter the packaging bag 500 from the distance between the first bag supporting component 10 and the second bag supporting component 30, reducing the impact of obstruction on the process of material entering the bag. In addition, after the material is loaded into the packaging bag 500, the driving component 50 also drives the first bag opening support portion 11 of the first bag supporting member 10 and the second bag opening support portion 31 of the second bag supporting member 30 to withdraw from the packaging bag 500, and keeps the first bag opening pulling portion 13 and the second bag opening pulling portion 33 located in the packaging bag 500, so that the first bag opening pulling portion 13 and the second bag opening pulling portion 33 can flatten the bag opening 501 of the packaging bag 500, which helps to prevent wrinkles from occurring at the bag opening 501 of the packaging bag 500 after the subsequent hot melt machine performs heat sealing on the bag opening 501 of the packaging bag 500.

[0069] like Figure 6As shown, the embodiment of the present application further provides a packaging device 1000, which includes a bag opening device 300 and a hot melt sealing mechanism 200 of any of the above-mentioned embodiments. The hot melt sealing mechanism 200 is located between the bag holding mechanism 100 and the packaging bag opening mechanism 700. The hot melt sealing mechanism 200 can heat-seal the bag opening 501 of the packaging bag 500 after being flattened by the bag holding mechanism 100.

[0070] In the packaging device 1000 provided in the embodiment of the present application, the driving component 50 can drive the first bag-supporting member 10 and the second bag-supporting member 30 to move. For example, after the bag mouth 501 of the packaging bag 500 is opened, the driving component 50 can drive the first bag-supporting member 10 and the second bag-supporting member 30 to move closer to each other, so that the arrangement between the first bag-supporting member 10 and the second bag-supporting member 30 is more compact, which helps the subsequent driving component 50 to easily drive the first bag-supporting member 10 and the second bag-supporting member 30 to extend into the packaging bag 500; the driving component 50 can also drive the first bag-supporting member 10 and the second bag-supporting member 30 located in the packaging bag 500 to move closer to each other. The bag-supporting member 10 and the second bag-supporting member 30 are far away from each other, so that the first bag-opening supporting portion 11 and the second bag-opening supporting portion 31 support the bag-opening 501 of the packaging bag 500, thereby preventing the packaging bag 500 from being unable to stably maintain an expanded shape due to its soft texture; and because the first bag-supporting member 10 and the second bag-supporting member 30 are far away from each other, the distance between the first bag-supporting member 10 and the second bag-supporting member 30 is larger, which helps the material to enter the packaging bag 500 from the distance between the first bag-supporting member 10 and the second bag-supporting member 30, thereby reducing the impact of obstruction on the process of material entering the bag. In addition, after the material is loaded into the packaging bag 500, the driving component 50 also drives the first bag opening support portion 11 of the first bag supporting member 10 and the second bag opening support portion 31 of the second bag supporting member 30 to withdraw from the packaging bag 500, and keeps the first bag opening pulling portion 13 and the second bag opening pulling portion 33 located in the packaging bag 500, so that the first bag opening pulling portion 13 and the second bag opening pulling portion 33 can flatten the bag opening 501 of the packaging bag 500, which helps to prevent wrinkles from occurring at the bag opening 501 of the packaging bag 500 after the subsequent hot melt machine performs heat sealing on the bag opening 501 of the packaging bag 500.

[0071] The packaging device 1000 may further include a bag-introducing device 400 , which may be used to put the material 600 into the packaging bag 500 when the bag-supporting mechanism 100 supports the bag opening 501 of the packaging bag 500 .
