The outer wall of the roller 2 is rotatably connected to a conveyor belt 3. A servo motor for driving the conveyor belt 3 is installed on one side of one support leg 1. The servo motor drives the roller 2 to rotate, so that the conveyor belt 3 can automatically transport the courier bags that need to be packaged.

[0031] In addition, a reinforcing rod is fixedly installed between the support legs 1, and a fixed frame 4 located above the conveyor belt 3 is fixedly connected to the reinforcing rod. Support plates 5 are fixedly connected to both sides of the fixed frame 4. An L-shaped fixed plate 6 is fixedly installed on one side of the upper end of the fixed frame 4. A storage slot 14 is fixedly installed between the support legs 1 below the conveyor belt 3. An inclined baffle 15 is fixedly installed on the side of the storage slot 14 away from the conveyor belt 3. The packaged express bags are stored in the storage slot 14, so that the express bags are automatically conveyed and fall into the storage slot 14 for storage. The baffle 15 can prevent the express bags from falling out of the storage slot 14.

[0032] In addition, a first sliding groove 8 is provided on the support plate 5, a first slider 9 is slidably installed in the first sliding groove 8, an electric telescopic rod 10 is fixedly installed on the first slider 9, a rotating frame 11 is rotatably connected to one end of the electric telescopic rod 10, and a clamping member 12 is installed on the rotating frame 11. The extension of the electric telescopic rod 10 drives the clamping member 12 to extend and clamp both sides of the express bag, and the rotation of the rotating frame 11 makes the clamped express bag in a vertical position.

[0033] It is worth noting that a first lead screw 13, which is threadedly connected to the first slider 9, is rotatably installed in the first slide groove 8. A drive motor 7 is fixedly installed on the top of the support plate 5. The output shaft of the drive motor 7 is fixedly connected to the first lead screw 13. When the drive motor 7 is started, the first lead screw 13 rotates, and the first slider 9 drives the express bag to move upward along the direction of the first slide groove 8, which facilitates the subsequent opening and sealing operation.

[0034] like Figure 1-3 As shown, the device also includes a spreading device, which is set on the fixed frame 4 for automatically spreading the express bag. The spreading device includes a horizontal plate 16 fixedly installed at the lower end of the fixed frame 4. A second slide groove 18 is provided on the horizontal plate 16. Two second sliders 20 are slidably installed in the second slide groove 18. Each of the second sliders 20 is fixedly connected to a spreading member 22. The second sliders 20 can drive the spreading member 22 to move and spread open the express bag that is clamped and moved upward.

[0035] Furthermore, a second lead screw 19 is rotatably installed inside the second slide groove 18 and threadedly connected to the two second sliders 20. The two second sliders 20 have opposite internal threads on their inner sides. A motor 17 is fixedly installed on one side of the horizontal plate 16. The output shaft of the motor 17 is fixedly connected to the second lead screw 19. When the motor 17 is started, the second lead screw 19 rotates, and the two second sliders 20 move towards each other, so that the opening member 22 can open the opening of the express bag, making it convenient to automatically add items for packaging.

[0036] like Figure 1-4 As shown, the device also includes a discharge device, which is set on the L-shaped fixed plate 6 for discharging residual air inside the express bag. The discharge device includes an electric push rod 24 fixedly installed on one side of the lower end of the L-shaped fixed plate 6. One end of the electric push rod 24 is fixedly connected to a mounting block 25. An electric slide rail 26 is provided on the mounting block 25. A moving block 27 is slidably installed in the electric slide rail 26. A pressure strip 28 is fixedly connected to the moving block 27. The electric push rod 24 pushes the mounting block 25 forward, so that the pressure strip 28 can contact the sealing edge of the express bag. The sliding of the moving block 27 in the electric slide rail 26 allows the pressure strip 28 to move left and right, pressing the sealing edge of the express bag against the bottom of the horizontal plate 16 and squeezing out the air bubbles at the sealing edge.

[0037] Furthermore, an air pump 23 is fixedly installed on the upper end of the L-shaped fixing plate 6. An air extraction pipe 21 is installed on the air pump 23 at the bottom end of the L-shaped fixing plate 6. The air extraction pipe 21 is located directly in front of the pressure strip 28. By using the air pump 23, the air extraction pipe 21 can extract the residual air inside the express bag, making the express bag more airtight and improving the quality and shelf life of the items.

[0038] The working principle of this embodiment is as follows: The extension of the electric telescopic rod 10 drives the clamping member 12 to extend and clamp both sides of the express bag. The drive motor 7 is started, causing the first lead screw 13 to rotate. The first slider 9 drives the clamping member 12 to move upward along the direction of the first slide groove 8, so that the clamping member 12 clamps the express bag and moves it to the bottom of the horizontal plate 16. The motor 17 is started, causing the second lead screw 19 to rotate. The two second sliders 20 move in opposite directions, driving the two opening members 22 to open the sealed edge of the express bag, making it easier to put in the packaged items. The push of the electric push rod 24 drives the mounting block 25 to move, so that the pressure strip 28 squeezes the sealed part of the express bag against the lower end of the horizontal plate 16. The sliding of the moving block 27 on the electric slide rail 26 allows the pressure strip 28 to move left and right to squeeze out the air bubbles at the sealed edge, avoiding poor sealing. The air pump 23 can be used to extract the air suction pipe 21 to remove the residual air in the express bag, making the sealing effect of the express bag better and improving the quality and shelf life of the items.

[0039] The above specific embodiments are merely several optional embodiments of this utility model.
