[0069] The device also includes four moving structures, which are all arranged on the top plate 5. The moving structures include: four servo cylinders 91, which are installed on the top plate 5; four sliders 92, each of which is slidably arranged inside the sliding opening 7, and the side surface of the slider 92 fits the inner surface of the sliding opening 7. The four sliders 92 are respectively fixed to the telescopic ends of the four servo cylinders 91. When the servo cylinder 91 is started, the slider 92 is driven to move. The servo cylinder 91 is designed to accurately control the position of the slider 92;

[0070] The device also includes four feed valve structures, which are respectively arranged on four movable structures, and the feed valve structures include: a valve body 101, which is fixed to the side of the slider 92; a valve core 102, which is slidably arranged inside the valve body 101; a valve stem 103, one end of the valve stem 103 is fixed to the valve core 102, and the other end of the valve stem 103 extends to the outside of the valve body 101, and the valve body 101 is provided with a hole position adapted to the valve stem 103; a bracket 104, which is fixed to the valve body 101, and the bracket 104 is a U-shaped structure; an electromagnet 105, which is installed on the bracket 104; a magnetic block 106, which is fixed to the end of the valve stem 103 away from the valve core 102, and the magnetic block 106 is arranged opposite to the electromagnet 105; a spring 107, one end of the spring 107 is connected ... connected to the valve body 101, and the bracket 104 is connected to the valve body 101, and the bracket 104 is connected to the valve body 101, and the bracket 104 is connected to the valve body 101, and the bracket 104 is connected to the valve body 101, and the bracket 104 is connected to the valve body 101, and the bracket 104 The inner surface of the valve body 101 is connected, and the other end is connected to the valve core 102; a feeding pipe 108, one end of the feeding pipe 108 is connected to the valve body 101, and the other end is connected to the barrel 6. The electromagnet 105 is energized and generates magnetism. When the electromagnet 105 is energized, it can attract the magnetic block 106, so that the magnetic block 106 moves upward and is adsorbed on the electromagnet 105. When the magnetic block 106 moves upward, it can drive the valve core 102 to move upward through the valve stem 103. In the initial state, the valve core 102 is just set opposite to the feeding pipe 108, and the valve core 102 blocks the feeding pipe 108. At this time, the liquid in the barrel 6 cannot flow out through the feeding pipe 108. When the valve core 102 moves upward, the valve core 102 no longer blocks the feeding pipe 108. At this time, the liquid in the barrel 6 will flow to the inside of the valve body 101 through the feeding pipe 108, and the automatic addition of materials can be realized.

[0071] The device also includes a cleaning structure, which is arranged on the mixing tank 3. The cleaning structure includes: an air source 131, which is installed on the mixing tank 3; four air supply pipes 132, one end of each of the four air supply pipes 132 is connected to the air outlet end of the air source 131, and the other end of each of the four air supply pipes 132 is connected to four valve bodies 101 respectively. The gas will enter the interior of the valve body 101 through the air supply pipe 132. When the high-speed flowing gas flows through the valve body 101, the airflow can blow the residual liquid in the valve body 101, so that the residual flow is cleared from the supply valve structure;

[0072] Each valve body 101 is provided with a sliding structure, which includes: a fixed tube 111, which is fixed on the valve body 101 and is connected to the valve body 101; a fixed ring 112, which is fixed to the end of the fixed tube 111 away from the valve body 101; a magnetic ring 113, which is arranged below the fixed ring 112; a sliding tube 114, which is slidably arranged in the fixed tube 111, and the inner surface of the fixed tube 111 and the outer surface of the sliding tube 114 are fitted with each other, one end of the sliding tube 114 extends to the outside of the fixed tube 111 and is fixedly connected to the magnetic ring 113, the bottom end of the sliding tube 114 and the bottom surface of the magnetic ring 113 are located on the same horizontal plane, and the sliding tube 114 The size is adapted to the size of the connecting cap 85; spring 2 115, spring 2 115 is arranged between the fixing ring 112 and the magnetic ring 113; guide rod 116, guide rod 116 is fixed on the magnetic ring 113, guide rod 116 passes through the fixing ring 112, and is slidably connected with the fixing ring 112. When the magnetic ring 113 is facing the connecting cap 85 made of magnetic material, the magnetic ring 113 will move downward under the action of magnetic attraction, and contact and adsorb with the connecting cap 85. When the magnetic ring 113 moves downward, it can drive the sliding tube 114 to move downward, so that the sliding tube 114 is inserted into the interior of the connecting cap 85. When the magnetic ring 113 and the connecting cap 85 are adsorbed together, the pipe mouth of the sliding tube 114 is just aligned with the top surface of the connecting cap 85.

[0073] The specific working principle of the present invention is as follows:

[0074] When the raw material proportioning device for producing and processing eosin staining solution proposed by the present invention is used, the driving member 2 is started and drives the rotating shaft 81 to rotate. When the rotating shaft 81 rotates, it drives the two mounting rods 82 to rotate. The two mounting rods 82 drive the plurality of stirring rods 83 to rotate. The raw materials in the mixing tank 3 are stirred and mixed by the plurality of stirring rods 83.

[0075] When batching, the servo cylinder 91 is started to drive the slider 92 to move, and the slider 92 can drive the valve body 101 to move when it moves. When the valve body 101 is facing the connecting cap 85, the servo cylinder 91 stops running. At this time, the sliding structure under the valve body 101 is just facing the connecting cap 85. For the sliding structure, when the magnetic ring 113 is facing the connecting cap 85 made of magnetic material, the magnetic ring 113 will move downward under the action of magnetic attraction, and contact and adsorb with the connecting cap 85. When the suction ring 113 moves downward, it can drive the sliding tube 114 to move downward, so that the sliding tube 114 is inserted into the interior of the connecting cap 85. When the magnetic suction ring 113 and the connecting cap 85 are adsorbed together, the pipe mouth of the sliding tube 114 is just aligned with the top surface of the connecting cap 85. At this time, the connecting cap 85 and the sliding tube 114 play a role in connecting the connecting tube 84 and the valve body 101. Further, the electromagnet 105 is energized and generates magnetism. When the electromagnet 105 is energized, it can attract the magnetic block 106, so that the magnetic block 106 moves upward. When the magnetic block 106 moves upward, it can drive the valve core 102 to move upward through the valve stem 103. In the initial state, the valve core 102 is just opposite to the feed pipe 108, and the valve core 102 blocks the feed pipe 108. At this time, the liquid in the barrel 6 cannot flow out through the feed pipe 108. When the valve core 102 moves upward, the valve core 102 no longer blocks the feed pipe 108. At this time, the liquid in the barrel 6 will flow into the interior of the valve body 101 through the feed pipe 108, and connect with the slide pipe 114. The pipe 84 enters the cavity 86 inside the rotating shaft 81, and the material can be automatically added. Therefore, the four moving structures and the four feeding valve structures can realize the automatic batching of the material. Furthermore, after the liquid enters the cavity 86, it will flow out through the plurality of openings 87. The plurality of openings 87 are evenly distributed on the rotating shaft 81, so that the material can be evenly distributed in the liquid inside the mixing tank 3. In addition, the stirring effect of the plurality of stirring rods 83 enables the material and the raw materials inside the mixing tank 3 to be quickly and evenly mixed.

[0076] After the automatic addition of materials is completed, the gas source 131 is powered on and the gas is pumped into the gas supply pipe 132. It should be noted here that when the electromagnet 105 is powered on, the magnetic block 106 is adsorbed on the electromagnet 105. At this time, the valve stem 103 and the valve core 102 will move upward. When the magnetic block 106 is adsorbed on the electromagnet 105, the valve core 102 will move to the top of the gas supply pipe 132. In this case, the gas will enter the interior of the valve body 101 through the gas supply pipe 132, and enter the interior of the cavity 86 through the sliding tube 114 and the connecting tube 84, and finally be sprayed into the raw materials in the mixing tank 3 through a number of openings 87. When the high-speed flowing gas flows through the valve body 101, the airflow can blow the residual liquid in the valve body 101, so that the residual logistics is cleared from the supply valve structure. Therefore, the high-speed flowing gas can flow to the valve. The residual materials in the body 101 are cleaned, thereby realizing the automatic cleaning of the feeding valve structure. The traditional water spray cleaning method is replaced by gas jet cleaning, which can save water resources. In addition, after the gas enters the cavity 86, it will be ejected through a number of openings 87 and form bubbles in the raw materials inside the mixing tank 3, providing an aeration effect for the raw materials inside the mixing tank 3. The aeration action and the stirring action cooperate with each other, which can improve the mixing effect and efficiency of the device for the raw materials. This design can utilize the gas used to clean the feeding valve structure to avoid the phenomenon of gas waste. It is worth mentioning that after the automatic addition of the material is completed, the amount of material remaining in the feeding valve structure is very small. After the residual material in the feeding valve structure follows the gas into the mixing tank 3, the raw material ratio inside the mixing tank 3 will not exceed a reasonable range.

[0077] Furthermore, a shielding structure is provided on the rotating shaft 81, and the shielding structure includes an annular floating block 121, which is made of a low-density material, so that the annular floating block 121 can float on the surface of the raw material inside the mixing tank 3. In this case, a plurality of shielding strips 122 on the annular floating block 121 can block a plurality of openings 87 located directly above the raw material. This special structural design allows the material to flow out only through the openings 87 immersed in the raw material, and not through the openings 87 located above the raw material. By accurately controlling the flow rate, the shielding structure can reduce operating costs, reduce the waste of raw materials and equipment maintenance costs, and improve production efficiency and economic benefits. In addition, the design of the shielding structure enables the material to be fully and evenly mixed with the raw materials inside the mixing tank 3, avoiding excessive material concentration on the top layer of the mixing tank 3, and ensuring the raw material proportioning effect of the device. It is worth mentioning that the design of the two mounting rods 82 enables the stirring rod 83 to be connected to the rotating shaft 81 without being directly connected, thereby avoiding the stirring rod 83 from hindering the up and down movement of the annular floating block 121. In addition, for any mounting rod 82, the shielding strips 122 on both sides thereof are in contact with the outer surface of the mounting rod 82. This design can prevent the annular floating block 121 from rotating during the up and down movement, thereby ensuring the shielding effect of the corresponding openings 87 by the plurality of shielding strips 122.

[0078] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
