[0025] Reference Figures 1-3 According to the embodiment of the powder mixing device of the utility model, a tank body 11 and a tank cover 12 are provided, the tank cover 12 is internally provided with a stirring shaft extending into the tank body 11, and the tank cover 12 is provided with a driving motor 13 for driving the stirring shaft to rotate, the bottom of the tank body 11 is further provided with a discharge pipe and a supporting leg, the discharge pipe 14 is provided with a discharge valve, and the tank cover 12 is further provided with a feeding port, which is the basic setting of the stirring tank. The driving motor 13 drives the stirring shaft to rotate, and then the material in the tank body 11 is stirred, and the discharge valve 15 can be opened to discharge the material, the closing plate 16 on the feeding port can be opened to feed the material, and the feeding port can be directly connected to the feeding pipe (not shown in the figure) to realize automatic feeding. This is the conventional design of the existing stirring tank, and its working mode and operating principle are well known to those skilled in the art, which will not be described here.

[0026] The curved surface of the tank body 11 is provided with a feeding opening 21, and the tank body 11 is further provided with a baffle 22 for closing the feeding opening 21, and the outer curved surface of the baffle 22 is provided with a transverse plate 23 extending transversely through the tank body 11, and further comprising a locking device for locking the position of the transverse plate 23.

[0027] When auxiliary material needs to be added or other small-dose raw materials need to be added, the staff can unlock the transverse plate 23 and push the baffle 22 inward, and then add materials through the feeding opening 21.

[0028] Specifically, as shown in the drawings, the locking device comprises a fixed plate 24 fixed to the curved surface of the tank body 11, and a latch 25 is slidably connected in the fixed plate 24, and the transverse plate 23 is provided with a slot through the upper and lower portions to accommodate the latch 25, when the latch 25 is pulled out of the slot, the transverse plate 23 is unlocked, and at this time the transverse plate 23 can be pushed inward, and the baffle 22 no longer closes the feeding opening 21. Figure 2

[0029] Further, in the second embodiment of the powder mixing device, in order to realize the weight control of the feeding, the curved surface of the tank body 11 on both sides of the feeding opening 21 is provided with a hinged plate 31, and an electronic scale 32 is arranged between the hinged plates 31, and a material frame 33 is arranged on the weighing platform in the electronic scale 32, and the staff can weigh the powder to be added through the material frame 33 and then put it into the feeding opening 21.

[0030] In order to further simplify the feeding process, so that the staff does not need to manually pick up the material frame 33 to pour the material, the hinged plates 31 are designed to be rotationally connected with a rotating shaft, and a bearing plate 34 is fixedly arranged on the rotating shaft, and the electronic scale 32 is fixedly arranged on the bearing plate 34, and the material frame 33 is fixedly arranged on the electronic scale 32, and the lower side of the hinged plate 31 is provided with a limiting plate 35.

[0031] When the bearing plate 34 is attached to the limiting plate 35, the bearing plate 34 and the electronic scale 32 are in a flat state to facilitate accurate weighing, and after the weighing is completed, the staff can push the bearing plate 34 to make it inclined, so that the material frame 33 enters the tank body 11 through the feeding opening 21, and the weighed powder in the material frame 33 can be poured into the tank body 11 to complete the feeding work.

[0032] ​In this embodiment, the left and right width of the material frame 33 is not greater than the upper and lower areas of the feeding port 21, so as to avoid interference between the material frame 33 and the wall of the tank 11 during the tilting of the bearing plate 34. In order to facilitate complete pouring and avoid material residue, the inner wall of the material frame 33 is inclined on the side near the tank 11, so that the opening of the material frame 33 expands from bottom to top.

[0033] For ease of operation, a handle 41 is provided at the bottom of the support plate 34 and at the top of the pin 25.

[0034] Specific material addition process:

[0035] First, the worker pulls the pin 25 upwards and pushes the baffle 22 and the horizontal plate 23 inwards. At this time, the material frame 33 is no longer blocked by the horizontal plate 23. Then, the worker puts the required powder into the material frame 33. The powder will be weighed by the electronic scale 32, and the reading will be directly displayed on the screen inside the electronic scale 32. After weighing, the worker can move the support plate 34 through the handle 41 so that the material frame 33 can enter the tank 11 through the filling port 21, and the powder in the material frame 33 can be poured into the tank 11 to complete the filling work.

[0036] Then, the staff reset the support plate 34 and abutted against the limiting plate 35, and then pulled the horizontal plate 23 outward so that the baffle 22 was once again attached to the inner wall of the tank 11 to close the filling port 21.

[0037] It should be noted that, as Figure 3 The angle of the support plate 34 shown is a non-limit angle. The support plate 34 can be rotated further at this angle so that the powder in the material frame 33 can be completely poured into the tank 11.

[0038] The side of the baffle 22 is provided with a sealing ring that can press against the inner wall of the tank 11, thereby achieving a tight seal and preventing powder leakage.

[0039] There is a certain amount of friction between the pin 25 and the fixing plate 24 to prevent it from slipping off naturally.

[0040] The baffle 22 and the horizontal plate 23 are reinforced to prevent changes in their angle.

[0041] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
