[0002] The material weighing tank is an important measuring component widely used in automated production lines. The accuracy of its value will directly affect the product quality. In the factory, due to the limitations of the site's plane layout and spatial structure, as well as the influence of the densely arranged pipelines for inlet and outlet materials, it is impossible or inconvenient to use weights as standard devices to calibrate the material weighing tank. In recent years, with the development of electronic technology and the improvement of intelligent control level, material weighing tank calibration devices (combined loading of multiple high-precision force measuring units) have begun to be used to replace weight loading to achieve the purpose of online calibration of material weighing tanks. The accuracy of the material weighing tank calibration device needs to be guaranteed by a higher level of traceability organization and traceability method. Summary of the invention

Preferably, the connecting bracket includes a connecting portion sleeved on the column and a supporting portion extending outward from the connecting portion, and the calibration device sensor and loading mechanism are arranged on one side of the column and connected below the supporting portion of the connecting bracket.

[0005] Preferably, the loading mechanism is a lifting device for realizing lifting and lowering of the column.

[0006] Preferably, the lifting device is a jack.

[0007] Preferably, there are at least three columns, and the columns are equidistant or symmetrically distributed.

[0008] Preferably, the standard measuring instrument has multiple physical channels, and the number of channels is not less than the number of the standard sensors.

[0009] A traceability method for a traceability mechanism of a material weighing tank calibration device, comprising: Step 1: Select the weight of the weight as M1; Step 2: Place the weight on the platform, lower the column through the loading device, so that the column is reliably connected to the standard sensor, transfer the standard load of the platform to the standard sensor of the traceability organization, read the value of the standard sensor through the standard measuring instrument, and record it as WA1; Step 3: Lift the column through the loading device to separate the column from the standard sensor.

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Combine the following Figure 1 The material weighing tank calibration device of the present invention is described as a traceability mechanism, comprising a material weighing tank calibration device and a traceability mechanism. The material weighing tank calibration device can provide an accurate weight standard for the weighing tank, and the calibration device is used to ensure that the weight displayed by the weighing tank is consistent with the actual weight.

[0019] The material weighing tank calibration device includes a base 1, a column 3, a connecting bracket 4, a platform 5, a calibration device display 8, a loading mechanism 9, and a calibration device sensor 10; the base 1 is arranged on the bottom surface as the foundation of the entire device, and a plurality of columns 3 are equidistantly or symmetrically arranged between the base 1 and the platform 5, which are used to support the platform 5 so that the platform 5 is in a horizontal state, and at the same time play the role of transferring the platform load downward to the lower structure.

[0020] The connecting bracket 4 is sleeved on the column 3, the calibration device sensor 10 is arranged below the connecting bracket 4, and the loading mechanism 9 is arranged between the calibration device sensor 10 and the base 1; the connecting bracket 4 includes a connecting portion sleeved on the column 3 and a supporting portion extending outward from the connecting portion, and the calibration device sensor 10 and the loading mechanism 9 are arranged on one side of the column 3 and connected below the supporting portion of the connecting bracket 4. The load on the platform 5 is transferred to the calibration device sensor 10 through the connecting bracket 4 and the loading mechanism 9, and the calibration device display 8 is used to display the load of the material weighing tank calibration device obtained by the calibration device sensor 10.

[0021] The loading mechanism 9 is a lifting device for lifting the column 3, such as a jack, an electric lifting device or a starting lifting device. The column 3 can be adjusted in height according to actual needs. When the load of the platform 5 needs to be transferred to the calibration device sensor 10 of the material weighing tank calibration device, the column 3 is lifted by the loading mechanism 9, and the column 3 is lifted to a suitable height position, so that the column 3 is separated from the standard sensor 2, and the calibration device sensor 10 is reliably connected to the column 3 through the connecting bracket 4, and the standard load of the platform 5 is transferred to the calibration device sensor 10, and the load of the material weighing tank calibration device is displayed by the display 8. When the load of the platform 5 needs to be transferred to the standard sensor 2 of the traceability mechanism, the column is lowered so that the column 3 is reliably connected to the standard sensor 2, and the calibration device sensor 10 is connected and separated from the column 3.

[0022] The column 3 is raised and lowered by the loading mechanism 9, so that the column 3 can adjust its height according to actual needs to meet the needs of detection and calibration, thereby better adapting to work requirements and improving work efficiency and quality.

[0023] The traceability mechanism includes a standard sensor 2, a standard measuring instrument 6 and a weight 7; the accuracy of the material weighing tank calibration device is directly related to the accuracy of material measurement. Through the calibration and verification of the traceability mechanism, the error of the device can be discovered and corrected in time to ensure the accuracy and reliability of its measurement results. In the process of calibrating the material weighing tank calibration device through the traceability mechanism, data and experience are continuously accumulated to provide a basis for the technical improvement and upgrade of the calibration device.

[0024] The weights 7 are placed on the platform 5 to provide a standard load; the standard sensor 2 is arranged between the bottom of each column 3 and the base 1 to obtain the weight of the weight loaded on the platform 5; the standard measuring instrument 6 is connected to the standard sensor 2 to display the value of the standard sensor 2.

[0025] The standard measuring instrument 6 has multiple physical channels, and the number of channels is not less than the number of the standard sensors 2. The standard measuring instrument 6 has multiple physical channels, and can collect data from multiple standard sensors 2 at the same time. The multiple channels of the standard measuring instrument 6 can connect these sensors at the same time, and obtain all relevant data at one time, without connecting the sensors one by one for measurement, which greatly improves the efficiency of data collection. The number of channels is not less than the number of standard sensors 2, so that the standard measuring instrument 6 can adapt flexibly when the number of sensors increases or the type of sensors is changed. A sufficient number of channels allows multiple standard sensors 2 to be measured simultaneously. When performing calibration work, the data of the calibrated sensor can be compared with the data of multiple standard sensors 2.

[0026] The traceability method of the traceability mechanism of the material weighing tank calibration device provided by the present invention comprises the following steps: Step 1: Select the weight of weight 7 as M1; Step 2: Place the weight 7 on the platform 5, lower the column 3 through the loading device 9, so that the column 3 is reliably connected to the standard sensor 2, transfer the standard load of the platform 5 to the standard sensor 2 of the traceability mechanism, read the value of the standard sensor 2 through the standard measuring instrument 6, and record it as WA1; Step 3: The column 3 is lifted by the loading device 9 so that the column 3 is separated from the standard sensor 2. The calibration device sensor 10 is reliably connected to the column 3 through the connecting bracket 4. The standard load of the platform 5 is transferred to the calibration device sensor 10. The load of the material weighing tank calibration device is displayed on the display 8 and recorded as WB1. Step 4: Place the weight 7 on the platform 5 again, and read the value of the standard sensor 2 through the standard measuring instrument 6, and record it as WC1; Step 5: Determine an error value according to the WA1, WB1, and WC1, and calibrate the material weighing tank calibration device according to the error value; △G1=2M1WB1 / (WA1+WC1)-M1; Wherein, ΔG1 is the error value.

[0027] Steps 1-5 may be repeated multiple times to obtain a number of error values, and the weighing tank calibration device may be calibrated based on the number of error values.

[0028] Verify calibration stability: The error value obtained by repeated measurements can be used to verify the stability of the weighing tank calibration device. If the fluctuation range of the error value is small during multiple measurements, it means that the performance of the device is relatively stable and the reliability of the calibration result is high. On the contrary, if the error value fluctuates greatly, it may mean that there are some potential unstable factors in the device, such as loose mechanical parts, aging of sensors, etc.

[0029] The weighing tank calibration device may face a variety of different working conditions in actual work, such as different load ranges, different ambient temperatures and humidity, etc. By repeating the steps many times to obtain the error values ​​under different conditions, the calibration process can take these factors into account more comprehensively, enhancing the adaptability and reliability of the calibration. Using multiple error values ​​can help determine the optimal calibration parameters for the weighing tank calibration device. Avoid over-calibration or under-calibration, improve calibration efficiency, and reduce unnecessary waste of resources.

[0030] By analyzing the error values ​​obtained from multiple measurements, the rationality of the current calibration cycle can also be evaluated. The calibration work can be reasonably arranged according to the actual situation to avoid excessive device errors due to untimely calibration, and to avoid wasting manpower, material and time resources due to too frequent calibration.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
