Description

Technical Field

[0001] The utility model relates to the technical field of electronic belt scale calibration equipment, in particular to an electronic belt scale calibration device. Background Art

[0002] An electronic belt scale is a device used to measure the quality of materials during transportation. It senses the weight of the materials through a load sensor and displays the quality of the materials after processing by an electronic metering system. It is widely used in coal mines, ports and other fields to achieve automated control and management of the production process.

[0003] During the long-term use of electronic belt scales, the zero point of the electronic belt scale is often offset due to factors such as belt tension changes and material falling. Therefore, the electronic belt scale must be calibrated regularly during use. At present, the electronic belt scale is calibrated by the circular chain code calibration method. When the circular chain code calibration is performed, automatic control is used, which can rotate dynamically to simulate the material flow, reducing the complexity of manual operation. In addition, the weight of the circular chain code calibration is fixed, so it has a higher calibration accuracy.

[0004] However, when performing the circular chain code verification, the circular chain code verification cannot fully and truly reflect the particle density of the material and the non-uniform distribution on the belt, so there is a certain error. Utility Model Content

[0025] An electronic belt scale calibration device, as shown in the attached manual Figure 1 As shown, including:

[0028] A driving assembly, which is disposed on the mounting frame 1 and is used to drive and support the chain code 3; and

The detection mechanism is used to detect the distance from the chain code 3 to the electronic belt scale 100, and the adjustment mechanism is used to adjust the contact area between the chain code 3 and the electronic belt scale 100.

[0030] In this embodiment, two mounting plates 2 are provided, so two groups of positioning components, driving components and adjusting components are provided corresponding to the mounting plates 2.

[0031] The positioning component includes a moving push rod 4, which is a linear hydraulic push rod. Both ends of the moving push rod 4 are fixedly connected to the mounting frame 1 and the mounting plate 2 respectively. The moving push rod 4 is used to adjust the height of the mounting plate 2. The moving push rod 4 is symmetrically arranged on both sides of the mounting plate 2.

[0032] The driving assembly includes a driving motor 5, a limit push rod 6 and a roller 7. The driving motor 5 is arranged on the mounting frame 1. The driving motor 5 is a reduction motor. The driving motor 5 is provided with an electromagnetic brake, that is, the output end of the driving motor 5 will not rotate when not started. The driving motor 5 is a prior art and can be selected according to actual conditions. The limit push rod 6 is arranged at the output end of the driving motor 5. When the limit push rod 6 is extended, the relative movement between the chain code 3 and the output wheel of the driving motor 5 can be further limited. The driving motor 5 and the chain code 3 are connected to each other and are used to drive the chain code 3 to rotate. The roller 7 is used to lift and support the chain code 3. A plurality of rollers 7 are provided, and a plurality of rollers 7 are evenly spaced and arranged on the mounting plate 2.

[0033] The detection mechanism includes a distance sensor 8, which is a reflective infrared sensor. The specific model can be selected according to actual conditions. The distance sensor 8 is used to detect the distance from the mounting plate 2 to the conveyor belt of the electronic belt scale 100. The distance sensor 8 is arranged under the mounting plate 2 and is used to detect the distance from the chain code 3 to the electronic belt scale 100.

[0034] The adjusting mechanism includes an adjusting seat 9, an adjusting push rod 10, an adjusting roller 11, a rotating motor 12, an adjusting push rod 2 13 and an adjusting roller 2 14. The adjusting seat 9 is fixedly connected to the mounting plate 2. The adjusting seat 9 is used to install the adjusting push rod 10 and the adjusting roller 11. The adjusting push rod 10 is arranged on the adjusting seat 9. In the present embodiment, the adjusting push rod 10 and the adjusting push rod 2 13 are both hydraulic push rods. The adjusting roller 11 is rotatably connected to the adjusting push rod 10. The rotating motor 12 is arranged on the mounting plate 2. The rotating motor 12 is used to drive the adjusting push rod 2 13 to rotate so as to adjust the chain code 3 arranged on the electronic belt scale 100. The adjusting roller 2 14 is arranged on the adjusting push rod 2 13.

[0035] Working principle: before physical calibration, the electronic belt scale 100 should be started and run for half an hour, and the instrument should be powered on and preheated for half an hour. The flow rate during calibration should be between 50% and 100% of the maximum flow rate. When calibrating the chain code 3, the drive motor 5 is not started, and the limit push rod 6 is extended. The installation plates 2 on both sides are lowered by extending the mobile push rod 4 so that the chain code 3 on the installation plates 2 on both sides is set on the conveyor belt of the electronic belt scale 100. At this time, the electronic belt scale 100 continues to operate, and the code blocks of the chain code 3 will rotate with the electronic belt scale 100. At this time, the electronic belt scale 100 can be calibrated. When it is necessary to adjust the number of code blocks on the conveyor belt of the electronic belt scale 100, according to the distance detected by the distance sensor 8, the adjustment push rod 1 10 is controlled to retract, and the rotating motor 12 drives the adjustment push rod 2 13 to rotate, and the number of code blocks on the conveyor belt is adjusted by controlling the length of the mobile push rod 4 and the adjustment push rod 2 13, so that multiple calibrations can be performed for different weights.

[0036] When the chain code 3 is cyclically calibrated, the mounting plates 2 on both sides are lowered by extending the push rod 4 so that the chain codes 3 on the mounting plates 2 on both sides are set on the conveyor belt of the electronic belt scale 100. When the electronic belt scale 100 is running, the chain code 3 is driven by the driving motor 5 to move and press on the conveyor belt of the electronic belt scale 100. The chain code 3 runs with the belt. When the chain code 3 rotates one circle, the weight acting on the conveyor belt of the electronic belt scale 100 is the standard weight of the chain code 3. When it rotates N circles, the weight is the number of circles (N) multiplied by the weight of the chain code 3, thereby realizing the dynamic simulation calibration of the belt scale;

[0037] When in use, the calibration test is performed by controlling the movement of the single-sided movable push rod 4 to control the chain code 3 of the single-sided mounting plate 2, so that the conveyor belt of the electronic belt scale 100 is calibrated with the chain code 3 only on one side, thereby more comprehensively simulating the distribution of materials on the conveyor belt of the electronic belt scale 100.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
