[0006] The mixing chamber has multiple feed pipes on its top; multiple rotating drums corresponding to the feed pipes and rotatably connected to the top of the mixing chamber, each rotating drum being sleeved on the outer wall of the corresponding feed pipe, and multiple first through holes circumferentially opened on the side wall of each rotating drum with its own central axis as the rotation axis; a drive assembly for driving the multiple rotating drums to rotate is provided on the outer wall of the mixing chamber; multiple conveying mechanisms corresponding to the multiple first through holes, each rotating drum having a conveying mechanism rotatably connected to the side wall of the rotating drum and communicating with the multiple first through holes; multiple boxes corresponding to the multiple rotating drums and all located on the top of the mixing chamber, each box being periodically connected to the rotating drum through multiple conveying mechanisms on the side wall of the corresponding rotating drum; wherein, different boxes are filled with different ingredients, and the conveying mechanisms are used to transport the ingredients in the boxes sequentially through the rotating drums and feed pipes to the interior of the mixing chamber.

[0026] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0027] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example

[0029] Please see Figure 1-3 As shown in the figure, this embodiment discloses a quantitative mixing device for a composite solvent, including a mixing tank 1. The interior of the mixing tank 1 is used for quantitative mixing of various ingredients. Multiple feed pipes 2 are arranged on the top of the mixing tank 1, with their central axes perpendicular to the top of the mixing tank 1. Each feed pipe 2 is connected to the interior of the mixing tank 1, that is, the feed pipe 2 can be used to transport the ingredients constituting the composite solvent into the interior of the mixing tank 1. Multiple rotating cylinders 3 are rotatably connected to the top of the mixing tank 1. The number of rotating cylinders 3 is the same as the number of feed pipes 2. Each rotating cylinder 3 is sleeved on the outer wall of the corresponding feed pipe 2. The inner wall of the rotating cylinder 3 and the outer wall of the feed pipe 2 are rotatably fitted together to prevent the ingredients entering the rotating cylinder 3 from falling between the outer wall of the rotating cylinder 3 and the inner wall of the feed pipe 2, which could easily contaminate the operating environment of the mixing tank 1 after long-term accumulation. A drive assembly is installed on the outer wall of the mixing tank 1. The drive assembly is used to drive the rotating drum 3 to rotate. Specifically, the drive assembly includes a forward and reverse motor 33, a gear 32, and a gear ring 31. The forward and reverse motor 33 is installed on the outer wall of the mixing tank 1, the gear 32 is installed on the outer wall of the output shaft of the forward and reverse motor 33, and the gear ring 31 is fitted on the outer wall of the rotating drum 3. The gear 32 and the gear ring 31 mesh with each other. That is, by starting the forward and reverse motor 33, the output shaft of the forward and reverse motor 33 rotates, which drives the gear 32 to rotate, and thus drives the rotating drum 3 to rotate through the gear ring 31. It is worth noting that the number of drive assemblies corresponds to the number of rotating drums 3, and each rotating drum 3 is driven to rotate independently.

[0030] Multiple first through holes 30 are circumferentially formed on the side wall of each rotating drum 3 with its own central axis as the axis of rotation. Multiple conveying mechanisms are then rotatably connected to the outer wall of each rotating drum 3, the number of conveying mechanisms corresponding to the number of first through holes 30. Each conveying mechanism can rotate on the outer wall of the rotating drum 3, and each conveying mechanism has an input end and an output end. The output end of the conveying mechanism communicates with the interior of the rotating drum 3 through the first through hole 30, while the input end can convey different discharge materials into the interior of the rotating drum 3. Notably, a box 7 corresponding to the number of rotating drums 3 is provided on the top of the proportioning box 1. The multiple conveying mechanisms on the outer wall of each rotating drum 3 can periodically communicate with the box 7, and different boxes 7 are filled with different ingredients. It is worth noting that there is a gap between the box 7 and the rotating drum 3, which allows the stationary conveying cylinder 4 to be unobstructed by the box 7 as the rotating drum 3 rotates.

[0031] The aforementioned conveying mechanism specifically includes a conveying cylinder 4, a conveying motor 40, a rotating rod 41, and a spiral blade 42. The outer wall of the conveying cylinder 4 is rotatably connected to the outer wall of the rotating cylinder 3. It is worth noting that the rotatable connection between the conveying cylinder 4 and the rotating cylinder 3 is located near the first through hole 30 of the rotating cylinder 3 to ensure that the conveying cylinder 4 can rotate on the outer wall of the rotating cylinder 3. Furthermore, the rotation direction of the conveying cylinder 4 is such that the top outlet of the conveying cylinder 4 rotates towards the first through hole 30 of the rotating cylinder 3. It should be noted that the vertical distance of the first through hole 30 on the rotating cylinder 3 along the central axis of the rotating cylinder 3 is greater than the rotation radius of the conveying cylinder 4 on the side wall of the rotating cylinder 3 to ensure that the conveying cylinder 4 can rotate until its outlet is located inside the rotating cylinder 3. A second through hole 43 is opened on the side wall of the feeding cylinder 4. The second through hole 43 is a certain distance from the bottom output end of the feeding cylinder 4. It should be noted that in this embodiment, the feeding cylinder 4 is a feeding cylinder with one open end and the other closed end. The open end is periodically connected to the box 7 at the top of the proportioning box 1, while the closed end is rotated towards the inside of the rotating cylinder 3. A feeding motor 40 is installed inside the feeding cylinder 4 near its closed end. A rotating rod 41 is installed on the output end of the feeding motor 40. The central axis of the rotating rod 41 is consistent with the central axis of the feeding cylinder 4. A spiral blade 42 is installed on the outer wall of the rotating rod 41. The spiral blade 42 is in rotational contact with the inner wall of the feeding cylinder 4. That is, when the feeding motor 40 runs, it drives the rotating rod 41 to rotate. The spiral blade 42 on the outer wall of the rotating rod 41 can form a spiral conveying mode inside the feeding cylinder 4, thereby conveying the ingredients inside the box 7 to the inside of the rotating cylinder 3, and finally entering the proportioning box 1 through the feed pipe 2. When the feed cylinder 4 rotates to the point where its top output end is inside the rotating cylinder 3, the second through hole 43 of the feed cylinder 4 will also be inside the rotating cylinder 3, so that the feed material discharged through the second through hole 43 can completely enter the feed pipe 2 inside the rotating cylinder 3.

[0032] Among the multiple conveying mechanisms rotatably connected to the outer wall of each rotating drum 3, the diameter of the rotating rod 41 set on the output end of the conveying motor 40 in different conveying drums 4 is different. Different diameters of the rotating rod 41 will result in different amounts of material entering the conveying drum 4 for conveying. That is, the space between the outer wall of the rotating rod 41 and the inner wall of the conveying drum 4 changes, thereby affecting the amount of material entering the conveying drum 4. This allows for quick changes to be made for different mixing ratios. When changing, simply rotate the conveying drum 4 located inside the housing 7 so that the conveying drum 4 is detached from the inside of the housing 7. Then rotate the rotating drum 3, which will drive the conveying drum 4 to rotate until the appropriate conveying mechanism rotates to the housing 7 and stops rotating the rotating drum 3. At this time, rotate the conveying drum 4 in the conveying mechanism located at the housing 7 so that the conveying drum 4 is inside the housing 7, thereby achieving different mixing ratios and realizing rapid mixing of composite solvents.

[0033] During the connection process between the conveying mechanism and the housing 7, the connection between the housing 7 and the conveying cylinder 4 in the conveying mechanism is that a connection port is opened on the housing 7, and a cover is hinged to the top of the housing 7 at the connection port. When the conveying mechanism needs to be replaced, the cover on the top of the housing 7 is opened so that the conveying mechanism can be taken out from the inside of the housing 7. After a suitable conveying mechanism is selected, the conveying mechanism is placed into the inside of the housing 7 through the connection port on the top of the housing 7, and then the cover is closed. At this time, the bottom of the conveying cylinder 4 in the conveying mechanism is in contact with the inner bottom of the housing 7, so as to facilitate the conveying of the ingredients inside the housing 7 to the proportioning box 1.

[0034] Curved blocks 44 are provided on the outer wall of the conveying cylinder 4 of each of the above-mentioned conveying mechanisms. The curved blocks 44 are located near the second through hole 43 of the conveying cylinder 4. When the material in the box 7 is a liquid material with high viscosity, in order to prevent the liquid material from flowing back along the outer wall of the conveying cylinder 4 after being discharged from the second through hole 43, thus affecting the surrounding environment of the mixing box 1, the curved blocks 44 are provided to prevent the liquid material from flowing back. In addition, guide rings 34 are provided on the inner wall of each rotating cylinder 3. The inner diameter of the guide rings 34 is smaller than the inner diameter of the feed pipe 2, which can prevent the material from entering the gap between the rotating cylinder 3 and the feed pipe 2.

[0035] A cleaning tank 5 and a water pump 6 are also provided on the top of the mixing tank 1. The cleaning tank 5 is filled with cleaning water. The side wall of the cleaning tank 5 is connected to the water outlet pipe 60. The water outlet pipe 60 passes through the water pump 6. When the water pump 6 is running, it can pump the cleaning water in the cleaning tank 5 into the water outlet pipe 60 and then spray it out from the water outlet pipe 60. That is, after the conveying mechanism on the side wall of each rotating drum 3 has been used for a certain period of time, the inside of the conveying cylinder 4 will be covered with residual ingredients. It is necessary to use the water outlet pipe 60 to correspond to the second through hole 43 of the conveying cylinder 4 to rinse the ingredients in the conveying cylinder 4, so as to avoid the residual ingredients in the conveying cylinder 4 from affecting the mixing of other compound solvents in the next batch. In addition, a collection box 35 corresponding to the conveying mechanism is provided circumferentially on the outer wall of the rotating drum 3 with its own central axis as the rotation axis. That is, after each conveying drum 4 is used, when it is in a free state, the bottom of the conveying drum 4 faces the top of the proportioning box 1. If there is still residual material in the conveying drum 4, it may fall from the inside of the conveying drum 4 to the top of the proportioning box 1. The collection box 35 can collect the fallen residual material to avoid the accumulation of too much residual material on the top of the proportioning box 1 and affecting the use environment of the proportioning box 1.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
