An input pipeline is arranged at the bottom of the feeding funnel. A control valve is arranged on the input pipeline. A metering component is arranged on one side of the input pipeline. The metering component is used for monitoring and controlling the proportioning amount of pigments for mixing. A mixing cavity is arranged in the mixing container. A stirring component is arranged in the mixing cavity. An outlet is arranged at the bottom of the mixing container.

[0007] By adopting the above technical solutions, in the proportioning device for pigment production designed by the utility model, during use, pigments are added into the input pipeline through the feeding funnels. A metering component is arranged on the input pipeline, which makes the proportioning amount more accurate through the metering component. After metering, the pigments are added into the mixing cavity for mixing. A stirring component is arranged in the mixing cavity, which makes the pigments mix more fully. After mixing, they are collected through the outlet. This proportioning device improves the proportioning accuracy and mixing effect.

[0008] Preferably, the metering component includes a flowmeter arranged on one side of the input pipeline. The flowmeter adopts an electromagnetic flowmeter. The flowmeter is connected to the control valve through a control system, and the control valve is adjusted according to the real-time monitoring of the flow rate.

[0009] By adopting the above technical solution, during use, a flow meter is installed on one side of the input pipeline, and then the flow meter and the control valve are controlled through a control system to monitor the pigment flow rate while adjusting the control valve.

[0010] Preferably, a partition is provided in the mixing chamber. The partition is located in the middle of the mixing chamber, and a through hole for the stirring rod to pass through is provided in the middle of the partition. The input pipeline is arranged on top of the partition. The input pipeline includes two shunt pipelines and one main pipeline, and the main pipeline penetrates through the partition.

[0011] By adopting the above technical solution, during use, the input pipeline is composed of two shunt pipelines and one main pipeline. After various pigments enter the shunt pipelines respectively, they enter the main pipeline for preliminary mixing after being accurately proportioned.

[0012] Preferably, the control valve includes a feed valve and a mixing valve. The feed valve is arranged between the feed hopper and the shunt pipeline to control the entry of pigments into the shunt pipeline, and the mixing valve is arranged between the shunt pipeline and the main pipeline.

First, the proportion of pigments entering the shunt pipeline is controlled. After confirmation, the entry of pigments into the main pipeline for preliminary mixing is then controlled, making the proportion more accurate during the mixing process.

[0014] Preferably, the stirring assembly includes a stirring rod arranged in the mixing chamber. A plurality of stirring blades are fixedly connected to the stirring rod. A driving assembly is arranged at one end of the stirring rod.

Therefore, a sealing cover is provided at the discharge port to block the discharge port. Since the airflow generated during the stirring process will cause the pigments to be lifted and mixed again, the sealing cover is opened after the mixing is completed.

[0020] Preferably, a transparent glass is provided on one side of the mixing container, and the transparent glass is used to observe the parameters on the flowmeter.

[0021] By adopting the above technical solution, during use, the parameters of the flowmeter are observed through the transparent glass on one side of the mixing container to ensure the normal use of the flowmeter.

Detailed implementation manners

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0031] The present utility model discloses a proportioning device for pigment production. Referring to Figure 1 and Figure 2 , it includes a mixing container 1. A plurality of feed hoppers 2 are arranged at the top of the mixing container 1. The feed hoppers 2 are vertically fixed to the top of the mixing container 1, and different numbers are set according to the types of pigments added. An input pipeline 3 is arranged at the bottom of the feed hopper 2. A control valve 4 is arranged on the input pipeline 3. The control valve 4 can control the opening and closing of the pipeline. A metering assembly 5 is arranged on one side of the input pipeline 3. The metering assembly 5 is used to monitor and control the proportioning amount of pigments for mixing. The metering assembly 5 includes a flowmeter 51 arranged on one side of the input pipeline 3. The flowmeter 51 in this solution adopts an electromagnetic flowmeter 51. The flowmeter 51 is connected to the control valve 4 through a control system, and the control valve 4 is adjusted according to the real-time monitoring of the flow rate. A mixing chamber 6 is arranged in the mixing container 1. A partition board 9 is arranged in the mixing chamber 6. The partition board 9 is horizontally fixed to the inner wall of the mixing chamber 6. The input pipeline 3 is arranged on the top of the partition board 9. The input pipeline 3 includes two shunt pipelines 31 and a main pipeline 32. The design of the main pipeline 32 is mainly to help the pigments be initially mixed. The main pipeline 32 penetrates through the partition board 9, and the pipe orifice of the main pipeline 32 is aligned with the bottom of the mixing chamber 6, so that the accurately proportioned pigments can smoothly enter the mixing chamber 6. The control valve 4 includes a feed valve 41 and a mixing valve 42. The feed valve 41 is arranged between the feed hopper 2 and the shunt pipeline 31, and its main responsibility is to regulate the flow rate of the pigments entering the shunt pipeline 31, while the mixing valve 42 is arranged between the shunt pipeline 31 and the main pipeline 32 to ensure that the pigments can enter the main pipeline 32 according to the preset ratio.

[0032] A stirring assembly 7 is provided in the mixing chamber 6. The stirring assembly 7 includes a stirring rod 71 disposed in the mixing chamber 6. A through hole 10 for the stirring rod 71 to pass through is provided in the middle of the partition plate 9. A plurality of stirring blades 72 are fixedly connected to the stirring rod 71. The stirring blades 72 are designed in a spiral shape and are made of a stainless steel alloy with stronger wear resistance. At the same time, the arrangement of the stirring blades 72 has also been optimized, enabling the pigments to be more evenly distributed during the mixing process. Such an improvement makes the eddy currents generated during the stirring process more complex, thereby improving the mixing uniformity and mixing speed of the pigments. At the same time, a non-stick coating 74 is coated on the stirring rod 71 and the stirring blades 72 to prevent the pigments from adhering to the stirring rod 71 and the stirring blades 72 during the mixing process. One end of the stirring rod 71 is provided with a driving assembly 73. In order to provide a more stable and adjustable power output, the driving assembly 73 includes a servo motor 731 fixed on the top of the mixing container 1. The output shaft of this motor is closely connected to the top of the stirring rod 71 to ensure the stability and efficiency of the stirring process.

[0033] Refer to Figure 2 and Figure 3 The bottom of the mixing container 1 is designed with a discharge port 8 to facilitate the discharge of the mixed pigments. A detachable sealing cover 11 is also cleverly connected to the discharge port 8. During the mixing process, the discharge port 8 is sealed with the sealing cover 11 to ensure that all the pigments are fully mixed. When the mixing is completed, the sealing cover 11 can be removed. In order to facilitate the operator to observe the parameters on the flow meter 51 and the situation inside the mixing chamber 6 in real time, a transparent glass 12 is provided on one side of the mixing container 1. This not only improves the operation convenience but also greatly enhances the safety of the operation process.

[0034] Working principle: For a pigment production proportioning device designed by the present utility model, during use, the operator sets the proportioning amount of each pigment through the control system according to the production requirements. Then, the feed valve 41 is opened, and the pigments flow from the feed hopper 2 into the shunt pipeline 31. At this time, the flow meter 51 starts to work, monitors the flow rate of the pigments in real time, and feeds the data back to the control system. The control system dynamically adjusts the opening degree of the control valve 4 according to the set proportioning amount and the real-time flow rate data to ensure that each pigment enters the mixing chamber 6 according to the set proportion. When the pigments enter the mixing chamber 6, they are fully mixed under the action of the stirring assembly 7, and finally, the mixed pigments that meet the requirements are obtained.

[0035] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
