Description

Technical Field

[0001] This utility model belongs to the field of belt scale technology, and in particular relates to an electronic belt scale calibration device. Background Technology

[0002] An electronic belt scale calibration device is a specialized piece of equipment used to accurately calibrate and verify the measurement accuracy of electronic belt scales. It typically consists of standard weights or physical calibration devices. By simulating material conveying conditions, it dynamically or statically verifies the weighing sensors, speed measuring devices, and cumulative functions of the belt scale, ensuring that it can accurately measure material flow and total volume in actual production. It is widely used in metrology management in industries such as mining, power, chemical, and grain to meet the accuracy requirements of trade settlement, process control, and quality traceability.

[0003] Most existing electronic belt scale calibration devices do not have the function of simulating dynamic loads in actual use. They cannot reproduce the actual working conditions such as impact, vibration, off-center loading and uneven distribution of materials during flow. This results in the inability to detect dynamic characteristic errors such as sensor response delay to dynamic signals, signal drift caused by structural resonance, and measurement deviation caused by roller wear or belt tension fluctuations. As a result, the calibration results are out of sync with the actual operating accuracy of the equipment, which is not conducive to the use of the equipment by the staff. In view of this, we propose an electronic belt scale calibration device. Utility Model Content

[0004] The purpose of this invention is to provide an electronic belt scale calibration device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an electronic belt scale calibration device, comprising:

[0006] A fixed frame, which is "n" shaped, has a hydraulic lifting rod fixedly installed on the top of its inner wall. The output end of the hydraulic lifting rod is fixedly connected to a connecting frame, which is also "n" shaped. A strong magnetic magnet is fixedly connected to the top of the inner wall of the connecting frame. A weight plate is provided at the bottom of the strong magnetic magnet. A first connecting plate and a second connecting plate are fixedly connected to the bottom of the connecting frame.

[0007] A first push plate is provided on one side of a first connecting plate, and a second push plate is provided on one side of a second connecting plate. Both the first and second connecting plates are slidably installed on the inner wall of the fixed frame. A through hole is provided on one side of the first connecting plate, and a slide rod is slidably installed inside the through hole.

[0008] A reciprocating moving component is disposed on one side of the first connecting plate and is used to drive the first push plate to reciprocate.

[0009] In this technical solution, the hydraulic lifting rod can drive the "n"-shaped connecting frame to move up and down, thereby adjusting the relative height between the strong magnetic magnet and the weight plate below, adapting to the initial positioning requirements of different calibration scenarios. The strong magnetic magnet fixes the weight plate by magnetic adsorption, ensuring its stable suspension. The sliding rod in the through hole provides guidance for subsequent reciprocating movement. The two "C"-shaped shells at the bottom of the fixing frame are connected to the pressure block by threaded rods. Rotating the threaded rods can push the pressure block to slide along the inner wall of the shell and press against the mounting surface, realizing the overall fixation of the device.

[0010] The motor drives the rotating shaft to rotate, and the reciprocating moving component pushes the weight plate to reciprocate. This structure simulates dynamic loads during belt scale calibration, overcoming the limitation of static weights which can only test constant loads. It more realistically reflects the dynamic response characteristics of the equipment, effectively detects measurement errors that static calibration cannot capture, thereby improving the accuracy and reliability of calibration results. This ensures that the equipment maintains high-precision measurement in actual operation, and facilitates use by staff.

[0011] In the above technical solution, further, two symmetrically distributed telescopic sleeves are fixedly connected to one side of both the first connecting plate and the second connecting plate. Telescopic rods are slidably installed inside the four telescopic sleeves, wherein two of the telescopic rods are fixedly connected to one side of the first push plate, and the other two telescopic rods are fixedly connected to one side of the second push plate.

[0012] In this technical solution, the first connecting plate and the first push plate can be fixedly connected by the telescopic sleeve and the telescopic rod, and the second connecting plate and the second push plate can be fixedly connected.

[0013] In the above technical solution, further, two symmetrically distributed first springs are provided on one side of both the first connecting plate and the second connecting plate, wherein two of the first springs are fixedly connected to one side of the first push plate, and the other two of the first springs are fixedly connected to one side of the second push plate. The four first springs are respectively sleeved on the outside of the four telescopic sleeves and the four telescopic rods. Three second springs are provided on one side of the second connecting plate, and all three second springs are fixedly connected to one side of the second push plate.

[0014] In this technical solution, the first and second push plates can be made to rebound by setting the first and second springs.

[0015] In the above technical solution, two fixing plates are fixedly connected to one side of the first connecting plate, and the two fixing plates are rotatably connected to the same rotating shaft. A motor is provided on one side of one of the fixing plates, and the output end of the motor is fixedly connected to the rotating shaft.

[0016] In this technical solution, the rotating shaft can be installed by setting two fixing plates, and the output end of the motor drives the rotating shaft to rotate by starting the motor.

[0017] In the above technical solution, the reciprocating moving component further includes a trapezoidal block, which is fixedly connected to one side of the slide rod. Multiple cams distributed at equal intervals are fixedly sleeved on the outside of the rotating shaft, and the multiple cams are adapted to the trapezoidal block.

[0018] In this technical solution, multiple cams on the rotating shaft rotate with the shaft and periodically push the trapezoidal block. The trapezoidal block drives the slide rod to slide in the through hole, thereby pushing the first push plate.

[0019] In the above technical solution, further, a support plate is fixedly connected to one side of one of the fixed plates, and the motor is fixedly mounted on the support plate.

[0020] In this technical solution, the support plate ensures that the motor will not rotate during operation.

[0021] In the above technical solution, further, the bottom of the fixing frame is fixedly connected to two symmetrically distributed shells, both of which are "C" shaped, and the top of both shells is threaded with threaded rods, both of which penetrate into the interior of the shells, and the bottom of both threaded rods is fixedly connected to pressure blocks, and the two pressure blocks are slidably installed on one side of the inner wall of the two shells respectively.

[0022] In this technical solution, the two "C"-shaped housings at the bottom of the fixing frame are connected to the pressure block by a threaded rod. Rotating the threaded rod can push the pressure block to slide along the inner wall of the housing and press against the mounting surface, thereby fixing the entire device.

[0023] The beneficial effects of this utility model are:

[0024] 1. The hydraulic lifting rod can drive the "n"-shaped connecting frame to move up and down, thereby adjusting the relative height between the strong magnetic magnet and the weight plate below, adapting to the initial positioning requirements of different calibration scenarios. The strong magnetic magnet fixes the weight plate by magnetic attraction, ensuring its stable suspension. The sliding rod in the through hole provides guidance for subsequent reciprocating movement. The two "C"-shaped shells at the bottom of the fixing frame are connected to the pressure block by threaded rods. Rotating the threaded rods can push the pressure block to slide along the inner wall of the shell and press against the mounting surface, realizing the overall fixation of the device.

[0025] 2. Start the motor to drive the rotating shaft to rotate. Through the set reciprocating moving component, the weight plate can be pushed to achieve reciprocating motion. Through the above structure, the weight plate can be pushed to reciprocate, thereby simulating dynamic load when calibrating the belt scale. This makes up for the limitation of static weights, which can only test constant loads. It can more realistically reflect the dynamic response characteristics of the equipment, effectively detect the measurement errors that static calibration cannot capture, thereby improving the accuracy and reliability of calibration results, ensuring that the equipment maintains high-precision measurement in actual operation, and thus facilitating the use of the staff.

Rotating the threaded rod 3 can push the pressure block 4 to slide along the inner wall of the housing 2 and press against the mounting surface to achieve the overall fixation of the device.

[0054] Working principle: This device uses an "n"-shaped fixed frame 1 as the basic support structure. The hydraulic lifting rod 5 fixedly installed on the top of its inner wall can drive the "n"-shaped connecting frame 6 to move up and down, thereby adjusting the relative height between the strong magnetic magnet 7 and the weight plate 8 below, adapting to the initial positioning requirements of different calibration scenarios.

The first push plate 14 transmits the driving force to the first connecting plate 9 through the telescopic sleeve 11, the telescopic rod 12 and the sleeved first spring 13, so that it slides back and forth along the inner wall of the fixed frame 1. At the same time, the second connecting plate 10 moves synchronously under the synergistic action of the corresponding telescopic sleeve 11, the telescopic rod 12 and the second spring 16, and finally pushes the weight plate 8 to achieve reciprocating motion. With the above structure, the weight plate 8 can be pushed to reciprocate, thereby simulating dynamic load when calibrating the belt scale. This makes up for the limitation that static weights can only test constant loads, and can more realistically reflect the dynamic response characteristics of the equipment.
