Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, and in particular to a double vacuum powder packaging machine. Background Technology

[0002] Vacuum powder packaging machines are specialized equipment designed for powdery and granular materials (such as flour, milk powder, feed, chemical powder, etc.). Combining vacuum extraction technology with automatic packaging functions, their core function is to remove air from the packaging and seal it to achieve the goals of preventing moisture, oxidation, and pollution, and extending the shelf life of the powder.

[0003] Existing vacuum packaging machines typically fill powder according to different quality requirements during vacuum packaging. In actual use, the powder is in a fluffy state, so the material hopper needs to be large to meet the requirements of continuous filling. When compressing and packaging, some gas will remain in the powder, which seriously affects the efficiency and quality of packaging. Therefore, it is necessary to research a double vacuum powder packaging machine. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of existing technologies where the powder is in a fluffy state and the material hopper needs to be large in size to meet the requirements of continuous filling, and some gas will remain in the powder when it is compressed and packaged. Therefore, a double vacuum powder packaging machine is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A double vacuum powder packaging machine includes a worktable, a front hopper mounted on top of the worktable, a feed valve, a vacuum source interface, and a screw reducer mounted in a row at the top of the front hopper, a transfer hopper connected through the bottom of the front hopper, and a discharge nozzle connected to the output end of the transfer hopper. A transmission rod is rotatably connected to both sides inside the transfer hopper, and a second feeding screw is fixed to the outer wall of the transmission rod. A vacuum packaging hopper is also mounted on one side of the worktable, and a second vacuum source interface is mounted in the middle of the side of the vacuum packaging hopper closest to the worktable. The discharge nozzle is located inside the vacuum packaging hopper.

[0007] Furthermore, the feed valve and the screw reducer are located on both sides of the top of the front hopper, and the screw reducer is located at the center of the top of the front hopper.

[0008] Furthermore, the output end of the screw reducer extends into the front hopper and is fixed with a hopper stirring screw blade. A feeding pipe is also fixed at the lower end of the hopper stirring screw blade, and a feeding screw blade is fixed to the outer wall of the feeding pipe.

[0009] Furthermore, a drive motor is also installed on the inner wall of the workbench, and the transmission rod extends from the end opposite to the vacuum packaging hopper to the outside of the transfer hopper and is connected to the output end of the drive motor via a conveyor belt.

[0010] Furthermore, the second feeding spiral blade is installed on the transmission rod of the transfer chamber and the discharge nozzle.

[0011] Furthermore, a dust suction pipe is installed on the bottom side of the vacuum packaging hopper, and an air inlet is also provided on one side of the top of the vacuum packaging hopper.

[0012] Furthermore, the upper part of the pre-loading hopper is funnel-shaped, the lower part of the pre-loading hopper is cylindrical, and the lower end of the feeding auger extends into the transfer hopper.

[0013] Furthermore, a door is installed on the front side of the vacuum packaging hopper, and the bottom of the vacuum packaging hopper is funnel-shaped.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses secondary compression to package powder, which more fully removes gas from the powder, ensures the tightness of the vacuum-packed powder, and further reduces the space required for powder transportation;

[0016] 2. This utility model compresses the powder before use, which ensures that the same size front hopper can store more powder when packaging, which not only meets the requirements of continuous filling, but also greatly saves on site costs. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example

[0022] A double vacuum powder packaging machine includes a workbench 1, with a front hopper 2 mounted above the workbench 1. A feed valve 3, a vacuum source interface 4, and a screw reducer 5 are arranged in a row at the top of the front hopper 2. The feed valve 3 and the screw reducer 5 are located on opposite sides of the top of the front hopper 2, while the screw reducer 5 is positioned at the center of the top of the front hopper 2. A transfer chamber 9 is connected through the bottom of the front hopper 2, and a discharge nozzle 10 is connected to the output end of the transfer chamber 9. A transmission rod 11 is rotatably connected to both sides inside the transfer chamber 9. A second feeding screw blade 13 is fixed to the outer wall of the transmission rod 11. The second feeding screw blade 13 is positioned on the transmission rod 11 between the transfer chamber 9 and the discharge nozzle 10. A vacuum packaging unit is also installed on one side of the workbench 1. The vacuum packaging hopper 14 has a vacuum source interface 2 15 installed in the middle of the side near the workbench 1. The discharge nozzle 10 is set inside the vacuum packaging hopper 14. The packaging bag is put on the discharge nozzle 10, and then the vacuum packaging hopper 14 is closed. The powder is initially compressed and vacuumed in the pre-loading hopper 2. During packaging, the powder is transported to the packaging bag in the vacuum packaging hopper 14 through the feeding spiral blade 2 13. During packaging, the vacuum packaging hopper 14 is evacuated to achieve secondary compression of the powder. It stops after reaching the preset weight. Then the vacuum packaging hopper is opened, and the packaging bag is used to complete one batch of powder packaging. The operation is convenient and can complete quantitative and rapid packaging operations in one go, which greatly improves the efficiency of vacuum packaging.

[0023] The output end of the screw reducer 5 extends into the front hopper 2 and is fixed with a hopper stirring screw 6, thereby realizing continuous compression and stirring of the powder and ensuring more complete compression of the powder. The lower end of the hopper stirring screw 6 is also fixed with a feeding pipe 7, and the outer wall of the feeding pipe 7 is fixed with a feeding screw 8, thereby ensuring that the powder can be smoothly transported to the transfer hopper 9.

[0024] The inner wall of the workbench 1 is also equipped with a drive motor 12. The transmission rod 11 extends from the end away from the vacuum packaging hopper 14 to the outside of the transfer hopper 9 and is connected to the output end of the drive motor 12 via a conveyor belt. Under the action of the drive motor 12, the transmission rod 11 can be smoothly driven to rotate stably, thereby driving the feeding spiral blade 13 to rotate in order to complete the packaging operation of the powder.

[0025] During the packaging process, some material dust will be suspended in the vacuum packaging hopper. A dust suction pipe 16 is installed on the bottom side of the vacuum packaging hopper 14, and an air inlet 17 is opened on the top side of the vacuum packaging hopper 14. This allows for dust suction when air is introduced through the air inlet, ensuring that no dust is generated when the material is taken out. The air inlet 17 is designed because the vacuum packaging hopper 14 is under negative pressure when packaged, while the outside is under positive pressure, making it impossible to open the hopper door. The air inlet is used to allow air to enter and balance the air pressure inside and outside the hopper, so that the hopper door can be opened more easily.

[0026] The upper part of the pre-loading hopper 2 is funnel-shaped to facilitate material discharge, and the lower part of the pre-loading hopper 2 is cylindrical. The lower end of the feeding spiral blade 8 extends into the transfer hopper 9 to achieve stable material conveying and avoid blockage. The vacuum packaging hopper 14 is equipped with a door on the front side, and the bottom of the vacuum packaging hopper 14 is funnel-shaped to facilitate the collection of suspended material dust.

[0027] 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.
