[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0031] like Figures 1 to 7 As shown, an embodiment of the present invention provides a bag-mouth packaging device for packaging design, including a packaging device body 1, wherein the packaging device body 1 includes a sealing machine, and a belt conveyor below for conveying packaging bags, and further includes:

[0032] A cleaning structure, which is located above the belt conveyor and is used to clean the residual materials at the sealing part of the packaging bag;

[0033] A clamping structure, which is provided on the cleaning structure and is used to fix the seal of the packaging bag so as to cooperate with the cleaning structure;

[0034] A squeezing structure, which is arranged on the cleaning structure and is used to limit the lower end of the packaging bag;

[0035] A driving structure, which is arranged on the clamping structure and is used to drive the clamping structure to clamp the seal of the packaging bag;

[0036] The clamping structure includes a clamping wheel 19, which is movably connected to the inner cavity of the moving frame 18. The top of the moving frame 18 is fixedly connected to a second motor 21, and the output shaft of the second motor 21 is fixedly sleeved with a conveying wheel 20.

[0037] The clamping structure also includes a gear 27, which is fixedly connected to the top of the storage tube 6. A spring assembly 2 30 is fixedly connected to the top of the mobile frame 4 near the clamping wheel 19. A driving rack 24 is fixedly connected to the top of the spring assembly 20. The driving rack 24 is meshed with the gear 27. There are two driving racks 24, which are staggered up and down. A lifting rod 22 is fixedly connected to the side of the driving rack 24 away from the mobile frame 18, and a pushing block 25 is fixedly connected to the side of the mobile frame 18 near the lifting rod 22.

[0038] The spring assembly 2 30 is composed of a damping telescopic rod 28 and a short spring 29. The lifting rod 22 is located on the moving path of the push block 25. The top side of the push block 25 close to the lifting rod 22 and the bottom side of the lifting rod 22 close to the push block 25 are both inclined surfaces.

[0039] The driving structure includes a motor 2, which is fixedly connected to the top of the packaging equipment body 1 near the middle extrusion soft strip 15 through a fixed plate. The output shaft of the motor 2 is fixedly sleeved with a bidirectional screw rod 3, and the two ends of the bidirectional screw rod 3 are respectively engaged with the moving frames 4 on both sides. A guide rod 26 is fixedly connected between the fixed plates, and the top of the moving frame 4 is movably sleeved on the guide rod 26.

[0040] In the embodiment, the packaging bag containing the material is first placed above the belt conveyor in the conveying device of the packaging device body 1 and between the two moving frames 4, and the sealing part of the packaging bag is located between the two clamping wheels 19, and then the motor 2 is started to drive the bidirectional screw 3 to rotate. Through the rotation of the bidirectional screw 3, the two moving frames 4 move along the axis direction of the bidirectional screw 3 and the guide rod 26, so that the moving frames 4 move in the direction close to the packaging bag;

[0041] Subsequently, the two clamping wheels 19 and the conveying wheel 20 first contact the upper position of the seal of the packaging bag, and the two clamping wheels 19 fit together to squeeze the upper position of the seal of the packaging bag. At the same time, the movable frame 4 stops moving, and the clamping wheels 19 and the conveying wheel 20 clamp and fix the upper position of the seal of the packaging bag to prevent the packaging bag from shifting during the subsequent cleaning process.

[0042] like Figure 1 , Figure 2 , Figure 5 As shown, the extrusion structure includes a limit plate 23, which is fixedly connected to one side of another spring component 5 close to the inner cavity of the moving frame 4. The spring component 5 is composed of a long spring 16 and a damping telescopic rod 17.

[0043] In the embodiment, when the driving structure drives the mobile frame 4 to move close to the packaging bag, the spring component 5 moves, and then the spring component 5 drives the limiting plate 23 to push the packaging bag placed on the conveyor belt of the packaging equipment body 1, so that the packaging bag and the material move to the middle position of the conveyor belt, which is convenient for subsequent packaging.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the cleaning structure includes a mobile frame 4, which is arranged on both sides of the belt conveyor. The side of the mobile frame 4 away from the center of the packaging equipment body 1 is fixedly connected to two spring components 5, and the two spring components 5 are respectively fixedly connected to the upper and lower sides of the mobile frame 4. One of the spring components 5 is fixedly connected to a moving frame 18 on the side close to the inner cavity of the mobile frame 4. The top of the mobile frame 18 is movably connected to a storage cylinder 6. The inner cavity of the storage cylinder 6 is fixedly connected to a pull rope 7. The top of the mobile frame 4 is away from the storage cylinder 6. A cylinder 9 is fixedly connected to one side of the storage cylinder 6, a coil spring 10 is fixedly connected to the inner cavity of the cylinder 9, a shrinking cylinder 11 is fixedly connected to the center of the coil spring 10, the end of the pull rope 7 away from the storage cylinder 6 is fixedly connected to the shrinking cylinder 11, a threaded rod 12 is fixedly connected to the bottom end of the shrinking cylinder 11, the top end of the threaded rod 12 is a smooth rod, a moving ring 13 is meshed on the surface of the threaded rod 12, and the side of the moving ring 13 close to the moving frame 4 is fixedly connected to a side extrusion soft strip 14 and a middle extrusion soft strip 15 through a connecting frame;

[0045] The cleaning structure further includes a limiting rod 8, which is fixedly connected to the top of the moving frame 4 and is used to guide the pull rope 7;

[0046] The middle extrusion soft strip 15 is located below and between the two side extrusion soft strips 14 .

[0047] In the embodiment, when the mobile frame 4 drives the clamping structure to clamp the sealing position of the packaging bag, the clamping wheels 19 on both sides will generate pressure after contact, and then the pressure is transmitted to the mobile frame 18, and the mobile frame 18 compresses the spring component 1 5, thereby driving the gear 27 to move toward the spring component 2 30, and the gear 27 and the driving rack 24 mesh and rotate, and then the gear 27 drives the storage cylinder 6 to rotate, and the storage cylinder 6 shrinks the drawstring 7 into the inner cavity of the storage cylinder 6. When the drawstring 7 shrinks into the inner cavity of the storage cylinder 6, the drawstring 7 pulls the shrink cylinder 11 to rotate (the initial drawstring 7 is wrapped around the inner cavity of the storage cylinder 6). On the surface of the shrink tube 11), when the shrink tube 11 rotates, it drives the coil spring 10 to rotate and accumulate elastic potential energy, and limits the pull rope 7 through the limit rod 8 to prevent the pull rope 7 from contacting other parts. At this time, when the shrink tube 11 rotates and drives the threaded rod 12 to rotate, the threaded rod 12 drives the movable ring 13 meshed with it to rise along the axis direction of the threaded rod 12. After the movable ring 13 reaches the smooth rod position at the top of the threaded rod 12, it will not continue to rise, and then drive the side extrusion soft strip 14 and the middle extrusion soft strip 15 to reach the sealing height of the packaging bag;

[0048] As the moving frame 4 moves, the side squeezing soft strips 14 and the middle squeezing soft strips 15 contact the top of the sealing portion of the packaging bag. At this time, the lifting rod 22 moves to contact the pushing block 25 and moves upward along the inclined surface of the pushing block 25, thereby driving the driving rack 24 to separate from the gear 27, so that the gear 27 loses its limit position.

[0049] When the gear 27 is separated from the driving rack 24, the coil spring 10 loses its limit, and the coil spring 10 releases its potential energy, driving the threaded rod 12 at the bottom of the shrink tube 11 to rotate. The rotation of the threaded rod 12 drives the movable ring 13 meshing therewith to steadily descend along the axial direction of the threaded rod 12, thereby driving the side extrusion soft strips 14 and the middle extrusion soft strips 15 to scrape down the material remaining at the sealing point, and the middle extrusion soft strips 15 are located below the side extrusion soft strips 14, so that the air can be discharged from the gap between the side extrusion soft strips 14 and the middle extrusion soft strips 15 to reduce the volume of the entire packaging bag.

[0050] When the processing is completed, the second motor 21 is started to drive the conveying wheel 20 to rotate, and the conveying belt of the packaging equipment body 1 to convey the packaging bag to the packaging part of the packaging equipment body 1 for heat sealing.

[0051] Working principle and use process: First, place the packaging bag filled with materials on the conveyor belt between the two mobile racks 4, and make the uppermost part of the packaging bag between the two clamping wheels 19, then start the motor 12 to drive the bidirectional screw 3 to rotate, drive the two mobile racks 4 to move toward the packaging bag, and drive the limit plate 23 to push the packaging bag through the movement of the mobile rack 4, and move the packaging bag to the middle of the conveyor belt of the packaging equipment body 1, so that the sealing part of the packaging bag and the sealing part of the packaging equipment body 1 are kept in the same straight line;

[0052] When the moving frame 4 moves, the clamping wheel 19 and the conveying wheel 20 first contact the upper part of the bag opening sealing part and fix it. As the moving frame 4 drives the driving rack 24 to move in the direction of the gear 27, the gear 27 is driven to rotate, and the storage tube 6 is driven to rotate through the gear 27;

[0053] When the gear 27 rotates, it drives the storage tube 6 to rotate and stores the drawstring 7 in the inner cavity of the shrink tube 11 into the inner cavity of the storage tube 6. When the drawstring 7 is pulled out of the inner cavity of the shrink tube 11, the shrink tube 11 rotates and drives the coil spring 10 to shrink. The rotation of the shrink tube 11 drives the threaded rod 12 to rotate, driving the side extrusion soft strip 14 and the middle extrusion soft strip 15 to move upward.

[0054] When the moving frame 4 drives the side extrusion soft strip 14 and the middle extrusion soft strip 15 to contact the sealing part of the packaging bag, the pushing block 25 moves to the bottom of the lifting rod 22 and pushes the lifting rod 22. The lifting rod 22 rises along the inclined surface of the pushing block 25, thereby driving the driving rack 24 to rise, so that the driving rack 24 is separated from the gear 27. At this time, the coil spring 10 loses its limit, and the coil spring 10 releases potential energy to drive the shrinking cylinder 11 to rotate, thereby driving the threaded rod 12 to rotate, and the side extrusion soft strip 14 and the middle extrusion soft strip 15 are driven to move downward through the threaded rod 12. In the process of the side extrusion soft strip 14 and the middle extrusion soft strip 15 moving downward, the material remaining at the sealing part of the packaging bag is scraped downward;

[0055] Then, the motor 21 is started to drive the conveying wheel 20 to rotate and transport the top of the packaging bag, and the bottom of the packaging bag is conveyed through the packaging equipment body 1. Then, the packaging bag is conveyed to the packaging part of the packaging equipment body 1 for bag opening sealing.
