[0027] like Figure 1-Figure 3 As shown, this embodiment proposes a powder mixing device, including a stirring box 10, a first stirring rod 20, a second stirring rod 30, a first motor 40 and a second motor 50. The first stirring rod 20 is vertically arranged in the upper half of the stirring box 10 and is connected to the first motor 40. The second stirring rod 30 is horizontally arranged in the lower half of the stirring box 10 and is connected to the second motor 50.
[0028] In detail, the first stirring rod 20 and the second stirring rod 30 are arranged vertically, and the second stirring rod 30 can have a conveying function while stirring.
[0029] It can be understood that this embodiment achieves efficient and uniform mixing of powder during the mixing process by setting up the upper and lower parts inside the mixing box 10 and setting stirring rods, and connecting different driving motors respectively; the first stirring rod 20 is vertically set in the upper half, driven by the first motor 40, and can effectively stir the powder in the vertical direction to eliminate the adhesion problem of high-viscosity powder during the mixing process; the second stirring rod 30 is horizontally set in the lower half, driven by the second motor 50, and is responsible for the horizontal mixing of the powder, ensuring the uniformity of the powder mixing. This upper and lower combined stirring method significantly improves the stirring efficiency and mixing quality compared to the single stirring mode of the prior art. At the same time, by controlling the rotation speed and running time of the stirring rods in the upper and lower parts respectively, the stirring intensity can be adjusted according to actual needs, avoiding energy consumption caused by excessive stirring, and achieving energy saving and emission reduction.
[0030] In a preferred embodiment, a partition 60 is provided inside the stirring box 10 to divide the interior of the stirring box 10 into an upper half and a lower half. One end of the first stirring rod 20 is connected to the top of the stirring box 10 and the other end is connected to the partition 60 .
[0031] It is understandable that the partition 60 can be disassembled according to actual conditions. When a small amount of powder mixing is required, the partition 60 can be added to concentrate the powder in the upper half of the mixing box 10 and mix it with the first stirring rod 20. Then, the partition 60 is opened or removed, and the powder is put into the lower half of the mixing box 10 and stirred and mixed again with the second stirring rod 30.
[0032] In a preferred embodiment, the partition 60 includes a fixed plate 61 and a movable plate 62 . The fixed plate 61 is provided with a notch for blanking, and the movable plate 62 is slidably disposed on the fixed plate 61 .
[0033] Specifically, the fixed plate 61 in this embodiment is provided with four notches in the vertical direction, a slide is provided in the horizontal direction in the middle of the fixed plate 61, and the movable plate 62 is slidably arranged in the slide. When the movable plate 62 is inserted into the slide, the notch is blocked by the movable plate 62, and when the movable plate 62 is pulled out of the slide, the notch opens.
[0034] It is understandable that the sliding arrangement of the movable plate 62 allows the partition 60 to be adjusted according to actual needs to adapt to different working environments and material processing requirements, thereby making more reasonable use of the limited space.
[0035] In a preferred embodiment, the first stirring rod 20 includes a first column 21 and a plurality of stirring teeth 22. The first column 21 is connected to the stirring box 10. The stirring teeth 22 are long strips and are arranged on the surface of the first column 21 along the length direction of the first column 21. The plurality of stirring teeth 22 are arranged equidistantly.
[0036] It is understandable that by designing the stirring teeth 22 to be long strips and equidistantly arranged along the length direction of the first column 21, the stirring area is effectively increased and the stirring efficiency is improved. This design not only makes the stirring more uniform, but also helps to reduce the dead angles that may appear during the stirring process, thereby improving the product quality while ensuring the stirring effect.
[0037] In this embodiment, the stirring tooth 22 includes a bracket 221 and a plurality of sleeves 222, the bracket 221 is connected to the first column 21, and the plurality of sleeves 222 are rotatably mounted on the bracket 221. In detail, compared with the prior art, the connection method between the bracket 221 and the first column 21 effectively enhances the stability of the entire structure, so that the reliability of the stirring tooth 22 during high-speed rotation is greatly improved. The design of the plurality of sleeves 222 can be rotatably mounted on the bracket 221, which is convenient for rapid adjustment according to different stirring requirements, greatly improving the convenience of operation and efficiency of use.
[0038] In some other embodiments, multiple motors or driving devices may be provided to connect multiple sleeves 222 one by one, and drive the sleeves 222 to rotate on the bracket 221, so that the sleeves 222 rotate around the first column 21 and rotate on themselves, thereby improving the mixing efficiency.
[0039] In a preferred embodiment, the second stirring rod 30 includes a second column 31 and a spiral piece 32 . The spiral piece 32 is disposed on the second column 31 . The second column 31 is rotatably connected to the inside of the stirring box 10 .
[0040] It is understandable that, compared with the prior art, the second stirring rod 30 greatly improves the stirring effect by setting the spiral blade 32 on the second column 31 and rotatably connected to the inside of the stirring box 10. This structural optimization not only improves the uniformity of stirring, but also simplifies the overall structure of the stirring device, making it easier to install and maintain. At the same time, the spiral blade 32 can push the powder forward while stirring the powder, making it easier to unload the powder.
[0041] In a preferred embodiment, an outlet 11 is provided at the bottom of the mixing box 10, and a flow meter 12 is provided at the outlet 11. Specifically, the flow meter 12 is mainly used to detect the outlet volume of the powder material, so that the operator can control the outlet volume of the powder material.
[0042] In addition, a feeding port 13 is provided on the mixing box 10, and an opening and closing door is provided at the feeding port 13. The powder mixing device also includes a frame 70, and the mixing box 10 is fixedly arranged on the frame.
[0043] The powder mixing device provided in this embodiment has the following advantages:
[0044] In this embodiment, by setting up an upper and lower part inside the stirring box 10 and setting stirring rods, and connecting different driving motors respectively, efficient and uniform mixing of powder during the stirring process is achieved; the first stirring rod 20 is vertically arranged in the upper half, driven by the first motor 40, and can effectively stir the powder in the vertical direction to eliminate the adhesion problem of high-viscosity powder during the stirring process; the second stirring rod 30 is horizontally arranged in the lower half, driven by the second motor 50, and is responsible for the horizontal mixing of the powder, ensuring the uniformity of the powder mixing. Compared with the single stirring mode of the prior art, this upper and lower combined stirring method significantly improves the stirring efficiency and mixing quality.
[0045] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
