Due to the diversity of its chemical structure and uses, this type of substance may exhibit different physical properties under different application conditions, among which viscosity is an important parameter.

[0003] Existing methods for determining the viscosity of castor oil polyoxyethylene ether typically involve placing a measuring cup containing castor oil under a rotational viscometer, and then rotating the test head on the rotational viscometer within the castor oil to measure the viscosity. However, in actual testing, when multiple samples need to be measured continuously, the measuring cups must be frequently cleaned and replaced manually, which is cumbersome, time-consuming, and inconvenient.

[0004] Therefore, it is necessary to design a castor oil polyoxyethylene ether viscosity measuring device that can quickly switch between measuring cups containing castor oil, facilitates rapid measurement, and is simple and convenient to operate. Utility Model Content

[0005] To overcome the shortcomings of existing castor oil polyoxyethylene ether viscosity measuring devices, which require frequent manual cleaning and replacement of measuring cups when multiple samples need to be measured continuously, making the operation cumbersome, time-consuming, and inconvenient, this invention provides a castor oil polyoxyethylene ether viscosity measuring device that can quickly switch between measuring cups containing castor oil, facilitating rapid measurement, and is simple and convenient to operate.

[0006] The technical implementation scheme of this utility model is as follows: a castor oil polyoxyethylene ether viscosity measuring device, including a base, an electric telescopic rod, a rotational viscometer, a test head, and a switching component. The electric telescopic rod is connected to the upper left side of the base. A connecting block is provided on the telescopic end of the electric telescopic rod. A rotational viscometer is connected to the right side of the connecting block. The test head is installed on the rotational viscometer. The base is provided with a switching component that can quickly switch to measure castor oil.

[0007] More preferably, the switching assembly includes a motor, gears, a turntable, heating pads, brackets, temperature sensors, and a measuring cup. The motor is connected to the lower right part of the base, and a gear is connected to the motor output shaft. The turntable is rotatably connected to the middle of the base, and a gear is also connected to the lower part of the turntable. Multiple heating pads are connected inside the turntable, and multiple brackets are connected to the upper side of the turntable. Two temperature sensors are connected to the inner side of each bracket. A measuring cup is placed on the heating pad at the rear right, and the measuring cup is located inside the bracket adjacent to it.

[0008] More preferably, it also includes feet and adjustment knobs. The lower part of the base is connected to multiple feet by threads, and the front and rear parts of the base are connected to two adjustment knobs by threads, with each adjustment knob contacting the adjacent feet.

[0009] More preferably, it also includes a bubble level, which is connected to the upper side of the center of the turntable.

[0010] More preferably, it also includes a cleaning cylinder and a jet nozzle, with the cleaning cylinder placed on the upper left side of the turntable and the jet nozzle connected to the fixed end of the electric telescopic rod.

[0011] More preferably, it also includes an air inlet, with the air inlet connected to the front side of the jet head.

[0012] The beneficial effects of this utility model are as follows: 1. By starting the motor, the gears rotate and mesh with each other, causing the turntable to rotate, which moves the measuring cup to the bottom of the test head. Then, the electric telescopic rod controls the rotational viscometer to move downward. The test is performed by rotating the test head. This achieves the effect of quickly switching the measuring cup containing castor oil, which is convenient for rapid measurement, simple operation and convenient use.

[0013] 2. This utility model adds cleaning water to the cleaning cylinder, then controls the rotation of the test head by rotating a viscometer, and cleans it with cleaning water. After cleaning, the gas is discharged to the surface of the test head through the air nozzle connected to the air supply pipe, and the test head is air-dried. This achieves the effect of cleaning and drying the test head after the measurement is completed, simplifying the operation process and preventing cross-contamination. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] A device for measuring the viscosity of castor oil polyoxyethylene ether, such as Figures 1-3 As shown, the device includes a base 1, legs 2, adjustment knobs 3, an electric telescopic rod 4, a rotational viscometer 5, a test head 6, and a switching assembly. The base 1 has four threaded connections to the legs 2 at its lower part. The front and rear parts of the base 1 are each threadedly connected to two adjustment knobs 3, which are in contact with the adjacent legs 2. The upper left side of the base 1 is connected to the electric telescopic rod 4. The telescopic end of the electric telescopic rod 4 is equipped with a connecting block. The right side of the connecting block is connected to the rotational viscometer 5. The test head 6 is installed on the rotational viscometer 5. The base 1 is equipped with a switching assembly.

[0022] like Figure 3 and Figure 4 As shown, the switching assembly includes a motor 7, a gear 8, a turntable 9, a heating pad 10, a bracket 11, a temperature sensor 12, and a measuring cup 13. The motor 7 is connected to the lower right part of the base 1, and the gear 8 is connected to the output shaft of the motor 7. The turntable 9 is rotatably connected to the middle of the base 1, and the gear 8 is also connected to the lower part of the turntable 9. Four heating pads 10 are connected inside the turntable 9, and four brackets 11 are connected to the upper side of the turntable 9. Two temperature sensors 12 are connected to the inner side of each bracket 11. The measuring cup 13 is placed on the heating pad 10 at the right rear, and the measuring cup 13 is located inside the bracket 11 adjacent to it.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a bubble level 91, a cleaning cylinder 14, a jet nozzle 15, and an air inlet 16. The bubble level 91 is connected to the upper middle part of the turntable 9, the cleaning cylinder 14 is placed on the upper left side of the turntable 9, the jet nozzle 15 is connected to the fixed end of the electric telescopic rod 4, and the air inlet 16 is connected to the front side of the jet nozzle 15.

[0024] When using this device, first place the base 1 in the castor oil polyoxyethylene ether viscosity measurement area, supported by the support legs 2. Then, loosen the adjustment knob 3 and adjust the support legs 2 by extending and retracting them. Fine-tune the support legs 2 according to the level detected by the bubble level 91 to ensure that the base 1 remains level. After adjustment, tighten the adjustment knob 3. Then, place the measuring cups 13 containing castor oil on the heating pad 10, so that the measuring cups 13 are located inside the support 11 and the test head 6 faces the measuring cups 13. Then, start the electric telescopic rod 4, which moves the rotational viscometer 5 downward, so that the test head 6 is inserted into the castor oil. Then, control the rotation of the test head 6 by the rotational viscometer 5 to perform the test. The viscosity of the castor oil is determined by measuring the torque on the test head 6. When it is necessary to measure the next sample of castor oil, control the rotational viscometer 5 to move upward by the electric telescopic rod 4, wipe the castor oil on the test head 6, and then start the motor 7, which drives the gear 8 to rotate. The gears 8 mesh with each other and move, carrying... The rotating turntable 9 moves the measuring cup 13 below the test head 6. The electric telescopic rod 4 then controls the rotational viscometer 5 to move downwards. Testing is performed by rotating the test head 6, allowing for quick switching between measuring cups 13 containing castor oil. This facilitates rapid measurement, is simple to operate, and convenient to use. During measurement, a heating pad 10 provides a certain temperature, which is detected by a temperature sensor 12, allowing castor oil to be tested at different temperatures. When cleaning the test head 6 is required, the turntable 9 rotates to position the cleaning cylinder 14 below the test head 6. Cleaning water is then added to the cleaning cylinder 14, and the rotational viscometer 5 controls the rotation of the test head 6. Cleaning is performed with the cleaning water. After cleaning, an external air supply pipe is connected through the air inlet 16, allowing gas to be discharged through the jet nozzle 15 onto the surface of the test head 6 for air drying. This allows for cleaning and drying of the test head 6 after measurement, simplifying the operation process and preventing cross-contamination.
