For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0016] like Figure 1 As shown, the structure of the novel automatic dosing device for painting pigments includes a quantitative material taking unit, a quantitative feeding unit and an electrically connected controller 3, wherein the quantitative material taking unit includes a plurality of material taking branches 11 respectively connected to various material tanks 10, a diaphragm pump 12 and a valve assembly 13 for flow detection and control arranged on the material taking branch 11, and the material taking branch 11 is connected to the metering tank 4; the quantitative feeding unit includes a plurality of feeding branches 21 respectively connected to each metering tank 4, a valve assembly 22 for flow detection and control is arranged on the feeding branch 21, the feeding branch 21 is connected to the dosing stirring kettle 5 through a negative pressure collecting pipe 23, and the negative pressure collecting pipe 23 is connected to the vacuum system 25 through a negative pressure valve 24.

[0017] Its working principle is as follows: the device is divided into two units: quantitative material taking and quantitative material feeding. When taking materials, the valve assembly 13 is opened, and the materials in various material tanks 10 are respectively injected into the metering tank 4 through their respective material taking branches 11 through the diaphragm pump 12; when feeding materials, the valve assembly 22 is opened, and the materials in each metering tank 4 are extracted through the vacuum system 25, and injected into the negative pressure collecting pipe 23 through the feeding branch pipe 21, and finally added into the batching stirring kettle 5.

[0018] In the structure constituting the above-mentioned novel automatic dosing device for painting pigments,

[0019] ——The above-mentioned metering tank 4 is used as a buffer container. The errors generated during the material taking and feeding process are found by comparing the flow detection of the material taking valve assembly 13 and the material feeding valve assembly 22. After being electrically connected to the controller 3, the material extraction amount is increased to compensate for the material filling difference. Further, the valve assembly 13 installed on the material taking branch pipe 11 includes a proportional valve a, an on-off valve or a one-way valve b; the valve assembly 22 installed on the material feeding branch pipe 21 includes a proportional valve a and a one-way valve b; the proportional valve a with flow detection function can control the flow size and detect the material flow, and the one-way valve b prevents the liquid from flowing back. A manual switch ball valve c1 or an electromagnetic switch ball valve c2 is set at the connection between the material feeding branch pipe 21 and the negative pressure collection pipe 23 to control the on-off of the pipeline or control the filling speed;

[0020] ——As a preferred embodiment, a base 41 is provided below the metering tank 4, and an electronic scale 42 is provided inside the base 41. The electronic scale 42 is also electrically connected to the controller 3. The actual conveying volume is fed back in real time through the weight change when the metering tank 4 is filled and drawn, which makes it easier for the controller 3 to automatically adjust and accurately draw various materials to ensure accurate proportioning relationship;

[0021] ——Furthermore, the above-mentioned controller 3 includes a PLC and / or Ethernet / serial communication conversion module, which is used to transmit the collected data to the host computer 31 through a switch or a conversion line. The host computer 31 includes a data analysis and storage module. In this embodiment, the interface is an RS232 interface or an RS232-usb method. The obtained flow value is transmitted to the host computer 31 through three different connection methods such as wired, Bluetooth or WIFI. The host computer 31 adopts the Siemens WINCC system, which includes a data analysis and storage module, that is, through the data processing software in the host computer 31, the detection data is analyzed and processed to achieve system management purposes, such as operation record monitoring, alarm management, trend management, report statistics and other functions, and the data is real-time, accurate and intuitive.
