[0021] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 4 The present invention provides a more detailed description of a powder packaging machine with a sealing function.

[0022] like Figures 1 to 4As shown in the figure, a powder packaging machine with sealing function according to an embodiment of the present invention includes a packaging machine outer shell 100 and a control assembly. The packaging machine outer shell 100 includes a packaging machine back plate 110, a packaging machine left side plate 120, a packaging machine right side plate 130, a packaging machine bottom plate 140, and a packaging machine top plate 150. The packaging machine bottom plate 140 and the packaging machine top plate 150 are rotatably connected to a packaging machine door 160. The packaging machine outer shell 100 has a packaging machine inner cavity 170 inside. The packaging machine back plate 110 is fixedly connected to a powder packaging machine. The material feeding device includes a powder inlet 210, which is located in the inner cavity 170 of the packaging machine. A powder weighing device is fixedly connected to the back plate 110 of the packaging machine, and a powder bag holding device is rotatably connected to the powder weighing device. The powder bag holding device is used to hold the powder bag. The powder bag holding device is located below the powder inlet 210. A powder bag sealing device is provided on the side of the top plate 150 of the packaging machine opposite to the inner cavity 170 of the packaging machine. The powder bag sealing device is used to seal the powder bag.

[0023] In operation, open the packaging machine door 160 to expose the powder bag holding device, and place the powder bag onto the device. Align the powder inlet of the powder bag with the powder inlet 210. After closing the packaging machine door 160, control the powder feeding device to feed the powder. Once the preset weight of powder has been reached, the feeding device will stop. Then, the packaging machine door 160 will open, and the powder bag sealing device will seal the powder bag, completing the sealing process. During this process, after the powder is fed, the powder packaging machine with sealing function automatically seals the bag. This eliminates the need for manual sealing and transferring the powder bag to another station for sealing.

[0024] In this utility model, the powder bag holding device includes a holding device side frame 410 and a holding device bottom 420. The holding device bottom 420 is rotatably connected to the holding device side frame 410. A bottom telescopic device 430 is connected to the holding device bottom 420. The other end of the bottom telescopic device 430 is rotatably connected to the holding device side frame 410. The bottom telescopic device 430 is used to control the rotation of the holding device bottom 420. The bottom telescopic device 430 is electrically connected to the control component.

[0025] After sealing, the empty component controls the bottom telescopic device 430 to open the bottom 420 of the bag-holding device, allowing the packaged powder bag to fall from the bag-holding device. The operator can then pick up the powder bag from the ground, eliminating the need to lift it from above. This is because the full powder bag may be heavy, and lifting it from above would be strenuous; lifting it from the ground is much easier. Multiple people can also lift the powder bag together, or a small trolley can be placed under the fallen bag for easy transport. The bottom telescopic device 430 can be a cylinder or a hydraulic system, etc.

[0026] To facilitate the removal of powder bags, the powder weighing device is equipped with a powder weighing connecting frame 310, several first bag-holding connecting rods 320, and several second bag-holding connecting rods 330. One end of the first bag-holding connecting rod 320 is rotatably connected to the side frame 410 of the bag-holding device, and the other end is rotatably connected to the powder weighing connecting frame 310. One end of the second bag-holding connecting rod 330 is rotatably connected to the side frame 410 of the bag-holding device, and the other end is rotatably connected to the powder weighing connecting frame 310. The powder weighing connecting frame 310 is connected to a bag-holding frame telescopic device 340, and the other end of the bag-holding frame telescopic device 340 is rotatably connected to the second bag-holding connecting rods 330. The powder weighing connecting frame 310 is parallel to the back plate 110 of the packaging machine. The bag-holding frame telescopic device 340 is electrically connected to the control components.

[0027] After the powder feeding device finishes feeding, the control component empties the bag holding frame telescopic device 340 and pushes the bag holding device outward into the inner cavity 170 of the packaging machine. As the bag holding device is pushed outward, the distance between the bag holding device and the ground also decreases. Therefore, when the powder bag moves away from the powder inlet 210 in both the horizontal and vertical directions, the powder bag is separated from the powder inlet 210. After the powder inlet 210 and the powder bag are separated, the powder bag sealing device seals the powder bag. After sealing, the bottom 420 of the bag holding device opens and lowers the powder bag.

[0028] To accurately measure the weight of the powder in the powder bag, a powder weighing connection frame 310 is fixedly connected to a powder weighing component 350. The powder weighing component 350 passes through the packaging machine back plate 110 and is electrically connected to the control component. During the feeding process, the powder weighing component 350 transmits the weight data to the control component in real time. When the control component determines that the weight of the powder has reached the preset value, it controls the powder feeding device to stop feeding.

[0029] In some embodiments, the packaging machine back plate 110 is connected to a vacuum device, which includes a vacuum pipe 610 fixedly connected to the packaging machine back plate 110. One end of the vacuum pipe 610 is disposed in the inner cavity 170 of the packaging machine, and the other end of the vacuum pipe 610 is fixedly connected to a vacuum assembly 620. The vacuum assembly 620 is used to vacuum the inner cavity 170 of the packaging machine, and is electrically connected to a control assembly.

[0030] After the packaging machine door 160 is closed, the vacuum assembly 620 evacuates the packaging machine cavity 170 through the vacuum pipe 610, maintaining the cavity within a suitable vacuum range. This serves two purposes: firstly, it keeps the air pressure inside the packaging machine cavity 170 lower than the external air pressure, preventing dust from overflowing; secondly, it ensures that the air pressure in the environment surrounding the powder bag is lower than the air pressure of the powder in the powder feeding device, facilitating powder feeding. Once the vacuum level in the packaging machine cavity 170 reaches a preset value, the control assembly activates the powder feeding device to begin feeding.

[0031] Understandably, to further reduce the amount of powder spilled from the packaging machine cavity 170 into the external environment after the packaging machine door 160 is opened, a dust extraction device is connected to the packaging machine back panel 110. The dust extraction device includes a dust extraction pipe 710, one end of which is located in the packaging machine cavity 170, and the other end of which is fixedly connected to a powder extraction assembly 720. The powder extraction assembly 720 is used to extract residual powder from the packaging machine cavity 170, and the powder extraction assembly 720 is electrically connected to the control assembly.

[0032] After the powder feeding device finishes feeding, the control component will activate the powder extraction component 720 to extract powder from the packaging machine cavity 170 through the dust extraction pipe 710, reducing the powder content in the packaging machine cavity 170. When the powder extraction component 720 determines that the extracted powder content is low, or after the control component has controlled the powder extraction component 720 to extract for a certain period of time, the powder extraction component 720 can stop extracting powder from the packaging machine cavity 170. After the powder extraction component 720 stops extracting, the control component will control the vacuum component 620 to restore the air pressure in the packaging machine cavity 170, and then open the packaging machine door 160 and push the powder bag holding device outward.

[0033] Understandably, the dust extraction pipe 710 is attached to the base plate 140 of the packaging machine. Since some dust is heavy or accumulates on the base plate 140 of the packaging machine after a long period of operation, this allows for better extraction of dust that falls from the base plate 140.

[0034] In this invention, the powder bag sealing device includes a sealing frame 510, a sealing telescopic component 520 connected to the sealing frame 510, and a sealing component 530 rotatably connected to the sealing component 530. The sealing component 530 is rotatably connected to the sealing frame 510, and the sealing telescopic component 520 is electrically connected to the control component. The powder bag sealing device is located outside the inner cavity 170 of the packaging machine. When the powder bag holding device is pushed out of the inner cavity 170 of the packaging machine, the control component controls the sealing telescopic component 520 to lower the sealing component 530, allowing the sealing component 530 to seal the powder bag. After sealing, the control component controls the sealing telescopic component 520 to retract the sealing component 530 back above the top plate 150 of the packaging machine. The sealing telescopic component 520 can be a cylinder or hydraulic device.

[0035] In some embodiments, the powder feeding device includes two powder feeding valves 220, each including a valve disc, one of which has an opening. The powder feeding valve 220 is electrically connected to a control component. A bag-expanding section 230 is provided on the powder inlet 210. This design allows for more precise control of the feeding speed. For example, when the feeding progress reaches 80%, the powder feeding valve 220 with the opening on its valve disc can be closed, resulting in a lower powder flow rate compared to the fully open state of the valve, making the feeding slower and easier to control. When the progress reaches 100%, the other powder feeding valve 220 is also closed, thus completing the powder feeding process.

[0036] Understandably, the packaging machine door 160 is rotatably connected to a door switch assembly, which includes a door switch section 810. The door switch section 810 controls the opening and closing of the packaging machine door 160 and is electrically connected to the control assembly. This design allows the control assembly to control the opening and closing of the door switch section 810 without manual intervention, thus improving the level of automation. The door switch section 810 can be a cylinder, hydraulic device, or motor, among other devices.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
