[0025] Example

[0026] like Figures 1 to 5 As shown, the present invention proposes a sealing device for express bag production, comprising a sealing machine 1, an operating slot 11, and an express bag 13. The sealing machine 1 is fixedly connected to the operating slot 11, and the operating slot 11 is provided with a sealing mechanism 14 for sealing the express bag 13. The device also includes: a T-shaped bracket 2 fixedly connected to the lower surface of the sealing mechanism 14, and a plurality of mounting screws 21 are provided on the top of the T-shaped bracket 2. The mounting screws 21 enable the pressing mechanism and the pressure regulating mechanism to be quickly disassembled and assembled at the bottom of the sealing mechanism 14. The upper surface of the operating slot 11 is provided with a sealing switch button 12 that causes the sealing mechanism 14 to move toward the express bag 13. The sealing switch button 12 is often used to start or stop the operation of the sealing machine. The operation is simple, and the user only needs to press a button to start or end the sealing process. The bottom end of the T-shaped bracket 2 is fixedly connected to a support sleeve 3. A connecting tube 31 is slidably inserted into the end of the support sleeve 3 close to the courier bag 13. The end of the connecting tube 31 inserted into the support sleeve 3 is fixedly connected to a pair of first sliders 32 that slide in limiting slots 34. The first sliders 32 ensure that the sponge pad 41 on the extrusion plate 4 does not rotate and moves horizontally when moving toward the courier bag 13. One end of the connecting tube 31 is fixedly connected to a pressing mechanism that presses against the courier bag 13 and then expels the air inside it; a pressure regulating mechanism is rotatably connected to the other end of the support sleeve 3 to increase or decrease the squeezing force generated by the pressing mechanism, thereby preventing the pressing mechanism from pressing too hard and causing damage to the package in the courier bag 13, and also preventing the pressing mechanism from pressing too little and causing incomplete exhaust of the air in the courier bag.

[0027] Furthermore, the pressing mechanism includes a spring 33 disposed within the support sleeve 3. The spring 33 adjusts the pressing force of the pressing mechanism by adjusting its position. One end of the spring 33 is fixedly connected to one end of the connecting tube 31. The other end of the connecting tube 31 is fixedly connected to a compression plate 4. The side of the compression plate 4 facing away from the connecting tube 31 is fixedly connected to a sponge pad 41. The sponge pad 41 can deform according to the shape of the package in the courier bag 13, thereby tightly fitting the compressed courier bag 13 to the package shape, thereby achieving the purpose of expelling most of the air in the courier bag 13.

[0028] Among them, the pressure regulating mechanism includes an adjusting baffle 35 slidably connected in the support sleeve 3, the other end of the spring 33 is fixedly connected to the adjusting baffle 35, a pair of limiting grooves 34 are opened inside the support sleeve 3, and a second slider 36 is fixedly connected to the adjusting baffle 35 and is inserted into the limiting groove 34 and slides.

[0029] Furthermore, the pressure regulating mechanism also includes a rotating seat 37 fixedly connected to the adjusting baffle 35, and a spiral push-pull rod 38 spirally sleeved with the support sleeve 3 is rotatably connected to the rotating seat 37. The end of the spiral push-pull rod 38 away from the rotating seat 37 is fixedly connected to a handle 39, and the handle 39 is used to save effort when rotating one end of the spiral push-pull rod 38.

[0030] In this embodiment, when the express bag production needs to use a sealing device, such as Figure 1 As shown, first place the package into the courier bag 13, and then press the sealing switch button 12 on the operating slot 11 to move the sealing mechanism 14 toward the courier bag 13 and seal the opening of the courier bag 13. Figure 2 As shown, when the sealing mechanism 14 moves toward the courier bag 13, it will drive the T-shaped bracket 2 to move. The T-shaped bracket 2 will in turn drive the connecting tube 31, the extrusion plate 4 and the sponge pad 41 to move. When the sponge pad 41 moves to press against the connecting tube 31, the sealing mechanism 14 has not yet moved to the courier bag 13 to seal it. The air inside the courier bag 13 is expelled by pressing the sponge pad 41. At the same time, since the sponge pad 41 is made of sponge, the sponge pad 41 after being deformed by pressing the package will fit the shape of the package very well, so that most of the air in the courier bag 13 is pressed out, and the sealed support sleeve 3 will take the shape of the package, avoiding the risk of damage caused by the bumps caused by the large amount of air in the packaged courier bag 13. When it is necessary to change the pressing force of the extrusion plate 4 according to the material of the package, avoid the situation where the pressing force of the extrusion plate 4 is too large or too small. Simply turning the handle 39 rotates the spiral push-pull rod 38. Since the spiral push-pull rod 38 is spirally connected to the support sleeve 3, the end of the spiral push-pull rod 38 away from the handle 39 pushes the adjustment baffle 35 to slide within the support sleeve 3. The second slider 36 on the adjustment baffle 35 engages and slides within the limiting groove 34, allowing the adjustment baffle 35 to slide horizontally within the support sleeve 3. The moved adjustment baffle 35 pushes the spring 33, which in turn drives the connecting tube 31 to slide horizontally along the limiting groove 34 via the first slider 32. Simultaneously, the connecting tube 31 drives the extrusion plate 4 closer to the courier bag 13. Consequently, when the sealing mechanism 14 moves the same distance toward the courier bag 13, the extrusion plate 4 now generates a greater extrusion force.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the content of this specification.
