Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixer testing, specifically to a mixer speed testing and calibration device. Background Technology
[0002] In industrial production and laboratory settings, mixers are crucial mixing equipment, and their rotational speed accuracy directly impacts material mixing effectiveness, reaction efficiency, and product quality. During production, it's essential to observe and calibrate the control accuracy of the controller and motor—that is, whether the motor can achieve the required rotational speed set by the controller and remain within a certain margin of error. This necessitates the introduction of third-party testing for calibration.
[0003] Considering issues such as rapid production on assembly lines, Hall effect speed sensors can be considered, as they are gradually being introduced due to their advantages such as non-contact measurement and strong anti-interference capabilities.
[0004] However, relying on the analytical display that comes with the Hall sensor, only the frequency value can be seen, lacking real-time monitoring of the speed waveform, making it difficult to detect waveform distortion caused by abnormal motor operation; secondly, the Hall sensor position is easy to adjust, which can improve work efficiency and does not affect the product from entering the next process.

[0023] As per the instruction manual Figures 1-4 As shown, this utility model is a mixer speed detection and calibration device, including a Hall sensor 1, also known as a Hall-type speed sensor. It is a Hall sensor that is made using the principle of Hall effect. The Hall effect is used to make the displacement drive the Hall element to move in the magnetic field to generate Hall potential, that is, the sensor that converts the displacement signal into the potential change signal. Conventional products are also equipped with a signal analysis display or can design their own signal reading board to analyze the waveform frequency.
[0024] It also includes a fixing plate 2, an observation structure 3, and a fixing structure 4. The fixing plate 2 is mounted on the external fixing structure, the observation structure 3 is mounted on the bottom of the fixing plate 2, and the fixing structure 4 is mounted on the bottom of the fixing plate 2. The Hall sensor 1 is mounted on the fixing structure 4. The observation structure 3 includes a connecting frame 5 and an oscilloscope placement box 6. The connecting frame 5 is mounted on the fixing plate 2, and the oscilloscope placement box 6 is mounted on the connecting frame 5. The oscilloscope placement box 6 has a cable pass-through port 7 on its side wall. When the oscilloscope is placed in the oscilloscope placement box 6, the detection waveform of the Hall sensor can be directly observed through the oscilloscope. It is possible to check whether the waveform is abnormal, because some waveforms with attenuation or sudden spikes can still be analyzed to obtain frequency values. However, if there is attenuation or spikes, it indicates that there is an abnormality in the rotation of the motor, and it is still necessary to find the cause. Using an oscilloscope for testing is more comprehensive. A connecting plate 8 is mounted on the connecting frame 5, and multiple instrument boxes 9 are mounted on the connecting plate 8. Testing tools can be added according to the actual technical personnel's suggestions and placed in the instrument boxes 9. The size of the instrument boxes 9 does not need to be uniform and can be selected according to the actual instruments placed in them. The instrument box 9 is equipped with a label strip 10, which is used to identify the name of the instrument used for testing.
[0025] As per the instruction manual Figure 5As shown, the fixing structure 4 includes a mounting base 11, a first connecting strip 12, an assembly frame 13, an additional strip 14, a second connecting strip 15, a fixing ring 16, an electric push rod 17, and a mounting frame 18. The mounting base 11 is installed on the bottom of the fixing plate 2. The first connecting strip 12 is located on the mounting base 11. The assembly frame 13 is installed on the first connecting strip 12. Multiple sets of assembly frames 13 are provided. The additional strip 14 is installed on the assembly frame 13. Another set of assembly frames 13 is installed on the additional strip 14. The second connecting strip 15 is installed on the assembly frame 13. The fixing ring 16 is located on the second connecting strip 15. The electric push rod 17 passes through the fixing ring 16. The mounting frame 18 is located on the output rod of the electric push rod 17 and is installed and connected to the Hall sensor 1. The length or number of additional strips 14 can be adjusted according to the actual required height.
[0026] As per the instruction manual Figures 1-2 As shown, a track 19 is provided on the ground below the fixed plate 2, and a sliding trolley 20 is provided on the track 19. The sliding trolley 20 needs to move the product to be inspected on the production line. The sliding trolley 20 is provided with a mounting frame 21 for mounting the product or semi-finished product to be inspected. The mounting frame 21 is provided with a reinforcing frame 22.
[0027] In practical use: Install the product onto the mounting bracket 21, push it to the appropriate position using the sliding trolley 20, fix the sliding trolley 20, then adjust the length of the electric push rod 17 to move the Hall sensor 1 to the test position, connect the oscilloscope, turn on the product, perform the test, check the speed displayed by the product controller, analyze the display data of the Hall sensor 1, and carefully observe the waveform on the oscilloscope.
