[0009] Through the above technical solution: during the sealing process of the packaging bag, the kinetic energy of motor 2 is used to drive metal gear 1 to rotate. The rotation of metal gear 1 then causes the rotation of metal gear 2 that meshes with it, which in turn causes the rotation of threaded rod 2. The rotation of threaded rod 2 drives the outer telescopic rod to move. A movable rod is fixed at the rear end of the telescopic rod to limit the range of movement of the telescopic rod. In addition, a heating rod is also equipped on the telescopic rod to achieve effective sealing of the packaging bag.

[0010] As a further description of the above technical solution:

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a packaging bag sealing device, comprising a frame 1, a motor 3 fixedly connected to the lower middle part of the frame 1, a metal bevel gear 4 fixedly connected to the output end of the motor 3, the kinetic energy of the motor 3 driving the metal bevel gear 4 to rotate, connecting plates 5 fixedly connected to the front and rear sides of the bottom of the frame 1, a rotating rod 6 rotatably connected to the top of the connecting plates 5, a metal bevel gear 7 fixedly connected to one end of the rotating rod 6, the metal bevel gear 4 meshing with the metal bevel gear 7, a metal bevel gear 8 fixedly connected to the other end of the rotating rod 6, and a connecting plate 9 fixedly connected to the front and rear sides of the bottom of the frame 1, the rotating rod 8 rotatably connected to the top of the connecting plate 9. 10.

The outer side of the foot pads 16 is threaded with screws 2 17, which serve as support for the whole.

[0040] Specifically, when sealing the packaging bag, it is necessary to ensure that the packaging bag is flat. The power of motor 3 drives the metal bevel gear 4 to rotate. The rotation of this gear will further cause the metal bevel gear 7 meshing with it to start rotating as well. The metal bevel gear 7 is equipped with a rotating rod 6, so the rotating rod 6 will also rotate. The rotating rod 6 is equipped with a metal bevel gear 8, which will cause the metal bevel gear 8 to start rotating as well. The rotation of the metal bevel gear 8 will cause the metal bevel gear 11 meshing with it to start rotating as well. The metal bevel gear 11 is equipped with a rotating rod 10, and the rotating rod 10 is also equipped with a threaded rod 12. The rotation of the threaded rod 12 will push the two fixed rods 13 to move, thereby achieving the flatness and sealing of the packaging bag.

The foot pads 16 are fixed by screws 17.

[0041] Reference Figure 3 and Figure 5The sealing mechanism 2 includes a placement box 201, which is fixedly connected to the top of the frame 1. A second motor 202 is fixedly connected to the front side of the inner top wall of the placement box 201. A first metal gear 203 is fixedly connected to the output end of the second motor 202. The first metal gear 203 is rotated by the second motor 202. A second threaded rod 204 is rotatably connected to the front side of the inner top wall of the placement box 201. A second metal gear 205 is fixedly connected to the upper middle part of the outer side of the second threaded rod 204. The first metal gear 203 and the second metal gear 205 are meshed.

Multiple heat dissipation holes 19 are equidistantly opened around the outer wall of the protective cover 18 to protect the box from heat dissipation.

[0042] Specifically, during the sealing process of the packaging bag, the kinetic energy of motor 202 is used to drive the rotation of metal gear 203. The rotation of metal gear 203 causes the meshing metal gear 205 to rotate, which in turn causes the threaded rod 204 to rotate. The rotation of threaded rod 204 drives the outer telescopic rod 206 to move. A moving rod 207 is fixed at the rear end of the telescopic rod 206 to limit the range of movement of the telescopic rod 206. At the same time, a heating rod 208 is installed on the telescopic rod 206 to achieve effective sealing of the packaging bag. A protective cover 18 is installed on the outside of motor 202, and heat dissipation holes 19 are opened on the protective cover 18 to play a role in protection and heat dissipation. The model of motor 3 and motor 202 is JZBOBO2.

[0043] Reference Figure 1 and Figure 2 A fixing block 20 is fixedly connected to the front left side of the outer wall of the frame 1. A hook 21 is fixedly connected to the outside of the fixing block 20, which can be used to hang some tools. A connecting block 22 is fixedly connected to the middle right side of the outer wall of the frame 1. A handle 23 is fixedly connected to the outside of the connecting block 22, which can be used to move the frame 1. A guardrail 24 is provided on the right side of the outer wall of the frame 1. A bolt 25 is threadedly connected to the top of the guardrail 24, which provides better protection.

[0044] Specifically, a fixing block 20 is fixed on the frame 1, and a hook 21 is installed on the fixing block 20 for hanging various tools. In addition, a connecting block 22 is installed on the frame 1, and a handle 23 is provided on the connecting block 22 for easy handling of the frame 1. A guardrail 24 is installed on the frame 1, and a bolt 25 is connected to the top of the guardrail by thread to enhance the protective effect.

[0045] Working principle: When sealing the packaging bag, it needs to be flattened before further operations. The kinetic energy of motor 3 drives metal bevel gear 4 to rotate, which in turn drives metal bevel gear 7 to rotate. A rotating rod 6 is mounted on metal bevel gear 7, which in turn rotates. A metal bevel gear 8 is mounted on rotating rod 6, which in turn drives metal bevel gear 11 to rotate. A rotating rod 10 is mounted on metal bevel gear 11, and a threaded rod 12 is mounted on rotating rod 10. The rotation of threaded rod 12 then drives two fixed rods 13 to move, thereby flattening and sealing the packaging bag.

[0046] When sealing the packaging bag, the kinetic energy of motor 202 drives metal gear 203 to rotate. The rotation of metal gear 203 drives the metal gear 205 that meshes with it to rotate, thereby causing threaded rod 204 to rotate. This, in turn, drives the outer telescopic rod 206 to move. A moving rod 207 is fixed behind the telescopic rod 206 to limit its movement. A heating rod 208 is also provided on the telescopic rod 206 to achieve the sealing of the packaging bag.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
