Description

Technical Field

[0001] This utility model relates to the technical field of Brinell viscosity measuring equipment, and in particular to a fully automatic thermoelectric refrigeration low-temperature Brinell viscosity measuring instrument. Background Technology

[0002] Viscosity, as a crucial parameter characterizing fluid flow resistance, is one of the core indicators for evaluating the rheological properties of substances. In industrial production and scientific research, viscosity measurement is widely used in petrochemicals, food processing, biomedicine, coatings manufacturing, and polymer material development, directly impacting product quality control, process optimization, and equipment design. With the increasing demands of modern industry for precision, automation, and real-time monitoring, viscosity measurement technology has evolved from empirical judgment to instrumental analysis, and from a single parameter to multi-dimensional characterization.

[0003] The prior art, disclosed in CN219799130U, discloses a lubricating oil testing platform, including a viscometer and a cylinder. The viscometer includes, but is not limited to, a rotor, which is movably connected below the viscometer's display. The cylinder is placed on top of the bottom end of the viscometer's support legs. A hydraulic cylinder is located on one side of the top of the support legs, with a hydraulic rod sliding at the bottom of the cylinder. A connecting plate is located at the bottom of the hydraulic rod, and one end of the connecting plate is fixed to one side of the cylinder. The hydraulic cylinder, located on one side of the top of the viscometer's support legs, moves the hydraulic rod up and down, thereby moving the connecting plate and the cylinder up and down. This allows the lubricating oil in the measuring cylinder to envelop the rotor, eliminating the need for manual adjustment of the rotor height. A pressing plate and a return spring are installed inside the cylinder, which, in conjunction, facilitate the fixing of measuring cylinders of different diameters within the cylinder.

[0004] However, the existing technology still has some shortcomings in its use: First, in the above structure, the measuring cylinder is lifted by a hydraulic cylinder to cooperate with the rotor for viscosity detection. Since the cylinder holding the measuring cylinder is always in a cantilever state, the measuring cylinder is prone to vertical swaying during the lifting process, which is not stable and can easily affect subsequent viscosity detection. Second, in real life, different rotors are required for viscosity detection of different liquids. When the above structure requires different rotors, the previous rotor needs to be disassembled and a rotor of a different specification needs to be installed, which is inefficient and labor-intensive for workers. Finally, the above structure does not have a preliminary cleaning structure for the rotor after testing. Therefore, the above structure cannot clean the rotor in a timely manner after testing, which can easily cause the test sample to adhere and solidify on the rotor (especially for testing liquids with high viscosity, such as glue), which is not conducive to subsequent rotor cleaning and has low functionality. Therefore, the existing technology needs to be further improved. Utility Model Content

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. This application includes a measuring mechanism, which comprises an automatically lifting unit and a rotor selection unit that selects different rotors according to the type of test sample. Therefore, when performing viscosity tests on different test samples, compared with the prior art which requires removing the existing rotor and installing a new rotor, the structure of this solution does not require rotor disassembly and replacement, thus greatly saving replacement time, improving rotor replacement efficiency, and improving viscosity testing efficiency.

[0018] 2. This application includes a container placement mechanism, which comprises a heating part that ensures the sample remains at a constant temperature during testing and stably places the sample container, and a moving part that moves the heating part away from directly below the rotor. Compared with the prior art, the structure in this solution not only ensures the sample remains at a constant temperature during testing to ensure the accuracy of the data, but also places the sample container more stably, without causing unnecessary impact on the testing, thus improving the testing quality. Furthermore, it allows for easier replacement of the sample container and quicker movement of the sample to the testing area, saving adjustment time for sample placement and thereby improving testing efficiency.

[0019] 3. In this application, the lifting unit and the rotor selection unit can be deflected at an overall angle by the motor 2, and a cleaning mechanism is provided on the base and on the deflection trajectory. After the rotor has finished testing the sample, it can be transferred to the cleaning agent in the cleaning mechanism in a timely manner, which effectively prevents the sample from adhering and solidifying on the rotor, making the rotor easier to clean and more practical.

[0034] Please see Figures 2-3The rotor selection unit 4 includes a cylinder 15, a top cover 16 that is detachably mounted on the top surface of the cylinder 15, a partition 17 that is fixedly mounted inside the cylinder 15, a turntable 18 that is rotatably mounted on the inner wall of the cylinder 15 below the partition 17, a plurality of cylinders 19 that are evenly distributed in a ring on the bottom surface of the turntable 18, and a connector 20 that is rotatably mounted inside each of the plurality of cylinders 19. The top surface of the connector 20 is on the same horizontal plane as the top surface of the turntable 18. Rotors 21 of different specifications are respectively mounted on the plurality of connectors 20. A motor 22 is fixedly mounted on the top surface of the partition 17. The output shaft of the motor 22 passes through and is fixedly connected to the top surface of the turntable 18. The rotor 21 selection unit 4 also includes a drive assembly 23 that is mounted on the top surface of the partition 17. The drive assembly 23 can drive the rotor 21 located directly below the drive assembly 23 to rotate.

[0035] Please see Figures 3-4 The drive assembly 23 includes two guide rods 24 symmetrically fixed between the top cover 16 and the partition 17. A mounting plate 25 is slidably mounted on the two guide rods 24. A telescopic cylinder 26 is fixedly mounted on the bottom surface of the top cover 16.

[0036] When the drive assembly 23 needs to drive a rotor 21 to rotate, the motor 3 22 is started. The motor 3 22 drives the mounting plate to rotate, so that the connector 20 of the rotor 21 of the required specifications rotates to the position directly below the plug-in 29. Then the telescopic cylinder 26 is started. The telescopic cylinder 26 drives the mounting plate 25, the motor 4 27, the column 28 and the plug-in 29 to move downward together, thereby inserting the plug-in 29 into the plug slot 30 on the top surface of the connector 20 directly below. Finally, the motor 4 27 is started again, which can drive the rotor 21 above the connector 20 to rotate.

[0037] Please see Figure 4 Each cylinder 19 is fixedly equipped with a stabilizer 31 on its outer side.

[0038] Please see Figures 5-6 The movable part 6 includes a movable plate 32. A sliding groove 33 is provided on the top surface of the base 1. The movable plate 32 slides in the sliding groove 33. A rotating rod 34 is hinged to the front side of the movable plate 32. A U-shaped limiting member 35 is fixedly provided on the front side of the base 1. When the movable plate 32 moves to the innermost end of the sliding groove 33, the rotating rod 34 can be rotated and engaged in the groove of the limiting member 35.

[0039] Please see Figures 5-6The heating unit 7 includes an annular column 36 disposed on the top surface of the movable plate 32. An accommodating space 37 is disposed inside the annular column 36. An annular heating plate 38 is disposed on the inner wall of the accommodating space 37. A container 39 containing the test sample is placed in the middle of the annular column 36. The outer diameter of the container 39 is adapted to the inner diameter of the annular column 36. A pipe opening 40 communicating with the accommodating space 37 is disposed on the front side of the movable plate 32 and the top surface of the annular column 36. A cap 41 is disposed on the pipe opening 40.

[0040] The container 37 can be filled with water through the opening 40 on the top surface of the annular column 36, and the water is heated at a constant temperature by the annular heating plate 38, so as to ensure that the liquid in the container 39 is at a constant temperature when it is measured again, thereby improving the accuracy of liquid viscosity detection.

[0041] When it is necessary to replace the water in the containment space 37, simply open the cover 41 on the front side of the movable plate 32 to drain the water in the containment space 37, then replace the cover 41, and then refill with new water through the pipe 40 on the annular column 3628.

[0042] When the moving plate 32 moves to the innermost end of the sliding groove 33, the container 39 placed inside the annular column 3628 is directly below the drive assembly 23, and the inner diameter of the container 39 is greater than the length of the stabilizer 31.

[0043] Please see Figure 7 The cleaning mechanism 8 includes a boss 42 fixed to the top surface of the base 1. A cylindrical tube 43 is fixedly mounted on the top surface of the boss 42. Several sliding blocks 44 are evenly distributed and slidably mounted on the outer wall of the cylindrical tube 43. A container 45 is held between the sliding blocks 44. The container 45 is filled with cleaning agent. Rectangular blocks are symmetrically mounted on both sides of the outer end of the sliding blocks 44. A spring 46 is fixedly mounted between the rectangular blocks and the outer wall of the cylindrical tube 43. An inclined surface is provided at the bottom end of the sliding blocks 44. The inclined surface facilitates the insertion of the container 45 between the sliding blocks 44. The cooperation of the sliding blocks 44 and the spring 46 can stably hold containers 45 of different sizes.

[0044] Please see Figure 1 An electrical control box 47 is fixedly installed on the top surface of the base 1. Through the electrical control box 47, the various driving components can be controlled and selected accordingly. The electrical control box 47 is existing technology and will not be described in detail here.

[0045] When this scheme is running, firstly, the receiving space 37 of the annular cylinder 36 is filled with water. Then, the water is heated and kept at a constant temperature by the annular heating plate 38. Then, the container 39 containing the test sample is placed in the middle of the annular cylinder 36 to stabilize the container 39 and maintain a constant temperature for the test sample in the container 39, so as to improve the accuracy of subsequent viscosity testing. Then, the moving plate 32 is pushed to the innermost end of the sliding groove 33, so that the container 39 is directly below the driving assembly 23. Then, the rotating rod 34 is rotated and inserted into the groove of the limiting member 35 to stabilize the moving plate 32. Then, the motor 22 is controlled to rotate according to the type of test sample, which drives the turntable 18 to rotate, so as to replace the rotor 21 located directly below the driving assembly 23. When the connector 20 on the required rotor 21 moves to the driving assembly 23, the rotor 21 is replaced. After the connector 29 is positioned directly below, the telescopic cylinder 26 is activated, causing the connector 29 to descend along with it. During the descent, the connector 29 is inserted into the insertion slot 30 on the top surface of the connector 20. At this point, motor 12 is activated, causing the rotor 21 selection section 4 to descend via the lead screw 11. As the rotor 21 selection section 4 descends, the rotor 21 and its stabilizer 31, connected to the connector 29, are gradually inserted into the sample, causing the lower ends of the rotor 21 and stabilizer 31 to be submerged in the test sample. Once the surface of the test sample has completely submerged the designated scale on the rotor 21, motor 12 is stopped, and motor 27 is activated. Motor 27 drives the rotor 21 to rotate via the connector 29 and the connector 20, thereby enabling viscosity testing of the test sample. The test data will be displayed on the screen of the control box 47.

[0046] After the viscosity test is completed, start motor 12 to disengage rotor 21 from container 39. Then start motor 2 to rotate the entire measuring mechanism 2. When rotor 21 is directly above container 45, start motor 12 again to insert rotor 21 and stabilizer 31 into container 45. The cleaning agent should be deeper than the rotor 21 in container 39 to ensure complete dissolution of the sample. Then start motor 27 to rotate rotor 21, thereby dissolving and removing the sample adhering to rotor 21 and stabilizer 31, preventing the sample from adhering and solidifying on rotor 21 and stabilizer 31 for easy cleaning later.

[0047] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as a limitation on the present invention.

[0048] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
