Description

Technical Field

[0001] This utility model relates to the field of weighing instrument technology, specifically a weighing instrument testing device. Background Technology

[0002] Weighing instruments are widely used in industry, agriculture, commerce, scientific research, and medical and health sectors. They measure the mass of objects using Hooke's Law or the lever balance principle of forces. A weighing instrument mainly consists of three parts: a load-bearing system (such as a weighing pan), a force transmission system (such as a lever force transmission system), and a display system (such as a scale). According to their structural principles, weighing instruments can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales. However, most existing weighing instrument testing devices rely on manual testing. Manual testing requires testers to operate and record various indicators of the weighing instrument one by one, such as repeatedly loading and unloading weights and manually reading the displayed values. The entire process depends on manual labor and cannot achieve automated batch testing. Especially when testing a large number of weighing instruments, it consumes a lot of time and manpower. Testers may have different understandings and implementations of testing standards. For example, when judging whether a weighing instrument meets the accuracy requirements, misjudgments may occur due to personal experience or subjective consciousness. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1:

[0021] Please see Figures 1-3 As shown, this utility model provides a weighing instrument testing device, including a base 1, a frame 8 fixedly installed on the top of the base 1, a third motor 9 fixedly installed on both sides of the top of the frame 8, a second threaded rod 12 fixedly installed at the output end of the third motor 9, a second threaded sleeve 11 threadedly installed on the front surface of the second threaded rod 12, a support plate 10 fixedly installed at one end of the second threaded sleeve 11 close to each other via a bracket, a second electric telescopic rod 21 fixedly installed at the bottom of the support plate 10 via a bracket, a smooth rod 20 fixedly installed at the bottom of the support plate 10 via a bracket and located at the lower end of the second electric telescopic rod 21, a slip ring 22 slidably installed on the front surface of the smooth rod 20, and a clamping ring 13 fixedly installed at the bottom of the slip ring 22 via a bracket.

[0022] This technical solution addresses the problem that most existing weighing instrument testing devices rely on manual testing. Manual testing requires testers to operate and record various indicators of each weighing instrument individually, such as repeatedly loading and unloading weights and manually reading displayed values. The entire process depends on manual labor and cannot achieve automated batch testing. Especially when testing a large number of weighing instruments, it consumes a lot of time and manpower. Testers may have different understandings and implementations of testing standards. For example, when judging whether a weighing instrument meets accuracy requirements, misjudgments may occur due to personal experience or subjective bias.

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figure 1As shown, a first motor 2 is fixedly installed on the right end of the base 1. A driven wheel 4 is fixedly installed on the output end of the first motor 2. A driving wheel 3 is connected to the front surface of the driven wheel 4 via a belt drive. A conveyor belt 15 is connected to the inner surface of the driving wheel 3 via a rotating shaft drive. A second motor 7 is fixedly installed on both sides of the base 1 via brackets. A first threaded rod 5 is fixedly installed on the output end of the second motor 7. A first threaded sleeve 6 is threadedly installed on the front surface of the first threaded rod 5. A detection table 14 is fixedly installed on one end of the first threaded sleeve 6 that is close to each other via a bracket.

[0025] By adopting the above technical solution, the first motor 2 is used to rotate the driven wheel 4. The driven wheel 4 and the driving wheel 3 are used to rotate the driving wheel 3 via the belt. The driving wheel 3 is used to make the conveyor belt 15 work. The second motor 7, the first threaded sleeve 6 and the first threaded rod 5 are used to adjust the height of the testing table 14.

[0026] Example 3:

[0027] This utility model is as follows Figures 1-3 As shown, springs 16 are fixedly installed on both sides of the top of the testing platform 14 by brackets. Clamping plates 17 are fixedly installed on the ends of the springs 16 that are close to each other. A first electric telescopic rod 18 is fixedly installed on the right end of the top of the testing platform 14 by brackets. A push plate 19 is fixedly installed on the output end of the first electric telescopic rod 18. A guide groove is opened on the inner wall of the frame 8, and the inner cavity of the guide groove is fixedly installed on the ends of the second threaded sleeve 11 that are far apart from each other by a guide rod.

[0028] By adopting the above technical solution, the weighing instrument is clamped and limited by the setting of spring 16 and clamping plate 17, the weighing instrument is pushed to the top of conveyor belt 15 by the setting of first electric telescopic rod 18 and push plate 19, and the second threaded sleeve 11 is limited by the setting of guide groove and guide rod.

[0029] The working principle of this utility model is as follows: Starting the third motor 9 drives the second threaded rod 12 to rotate. The rotation of the second threaded rod 12 causes the second threaded sleeve 11 to adjust its height. The height adjustment of the second threaded sleeve 11 causes the support plate 10 to adjust its height. Then, the support plate 10 causes the clamping ring 13 to adjust its height. Next, starting the second electric telescopic rod 21 causes the slip ring 22 to move left and right via the smooth rod 20. The left and right movement of the slip ring 22 causes the clamping ring 13 to move left and right. Then, the clamping ring 13 clamps and limits the weight. Finally, the clamping ring 13 places the weight on top of the weighing instrument for testing. After completion, the second motor 7 is started to drive the first threaded rod 5 to rotate. The rotation of the first threaded rod 5 drives the first threaded sleeve 6 to adjust its height. The height adjustment of the first threaded sleeve 6 drives the testing platform 14 to the top of the conveyor belt 15. Then, the first electric telescopic rod 18 is started to drive the push plate 19 to move left and right. The left and right movement of the push plate 19 pushes the weighing instrument to the top of the conveyor belt 15. Then, the first motor 2 is started to drive the driven wheel 4 to rotate. The rotation of the driven wheel 4 drives the driving wheel 3 to rotate via the belt. The rotation of the driving wheel 3 drives the conveyor belt 15 to work, and the work of the conveyor belt 15 drives the weighing instrument to be transported.
