[0003] First, the traditional calibration method requires manual addition and subtraction of weights. This operation method is not only inefficient and increases the workload of workers, but also in a long-term, high-intensity production environment, manual operation is easily affected by factors such as fatigue and distraction, resulting in inaccurate calibration results.

[0004] Secondly, the small contact area between the weight and the belt is another important issue; due to the limited contact area, the pressure distribution generated by the weight on the belt is often uneven; this uneven pressure distribution will have an adverse effect on the weighing sensor, resulting in reading errors of the weighing sensor; in actual applications, this error may accumulate and amplify, ultimately affecting the measurement accuracy and product quality of the entire production line. Utility Model Content

In addition, the contact area between the weights and the belt is small, and the pressure distribution is uneven, which affects the reading of the weighing sensor, thereby affecting the measurement accuracy of the production line and the product quality.

[0015] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0016] First: This device successfully achieves accurate calibration of the belt scale by simulating the movement of the calibration trolley and counterweights. This method not only significantly improves the convenience of calibration, but also greatly enhances the flexibility of calibration. It is particularly worth mentioning that this device can automatically increase or decrease the weighing weights. This function makes the calibration process more efficient and accurate. This calibration device and operation method ensure the accuracy and stability of the belt scale, thereby effectively meeting the stringent requirements of the production process.

[0017] Second, by introducing a clamping claw design that can be rotated arbitrarily and precisely adjusted in height, this device not only realizes the automatic increase and decrease of the counterweight, significantly improving the efficiency of the calibration work, but also abandons the traditional weight calibration method; in the traditional method, the contact area between the weight and the belt is small, which leads to a decrease in weighing accuracy; due to the limited contact area, the pressure generated by the weight on the belt is unevenly distributed, which in turn affects the reading of the weighing sensor and increases the risk of error;

DETAILED DESCRIPTION

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The utility model embodiment provides a coal feeder belt scale calibration device, such as Figure 1-4 As shown, it includes a support platform 1; a connecting body arranged beside the support platform 1; and an adjusting mechanism arranged on the connecting body; wherein the adjusting mechanism includes: a supporting shell 2; a receiving plate 3 sliding on the outside of the supporting shell 2; a screw slide 4 arranged on the bottom side of the receiving plate 3; a mechanical arm 5 arranged at the moving end of the screw slide 4; a clamping claw 6 arranged at the grasping end of the mechanical arm 5; a supporting plate 7 is arranged on the side of the supporting shell 2 away from the receiving plate 3; and a plurality of counterweights 8 are arranged on the supporting plate 7.

[0027] It should be noted that, since the traditional method requires manual addition and subtraction of weights, it is inefficient and easily affected by human factors, resulting in inaccuracy. In addition, the contact area between the weights and the belt is small, and the pressure distribution is uneven, which affects the reading of the weighing sensor 19, and thus affects the measurement accuracy and product quality of the production line. This solution introduces a clamping jaw 6 design that can be rotated arbitrarily and accurately adjusted in height, thereby realizing the automatic addition and subtraction of the counterweight weights 8. This design greatly improves the efficiency of the calibration work and reduces the time and errors of manual operation. At the same time, it abandons the traditional weight calibration method, avoids the problems of small contact area between the weights and the belt, uneven pressure distribution, etc., thereby improving the accuracy of weighing; in addition, this device also adopts the design of a calibration trolley 20, which ensures the uniform distribution of pressure on the belt by increasing the contact area with the belt. The calibration trolley 20 can move smoothly through the weighing area, highly simulating the situation of actual materials passing through the belt scale, further enhancing the accuracy and reliability of the calibration.

[0028] Specifically, in this embodiment, the scheme mainly includes a support platform 1; the support platform 1 serves as the basis of the entire calibration device and is responsible for supporting and fixing the connecting body and the adjustment mechanism; during the calibration process, the height of the lower clamping jaw 6 is first adjusted by sliding the receiving plate 3; then, the motor of the screw slide 4 drives its moving end, so that the mechanical arm 5 below can accurately move the clamping jaw 6 to the desired position and grab the counterweight 8; the clamping jaw 6 places the carried counterweight 8 in the counterweight slot 21 of the calibration trolley 20, and then the calibration trolley 20 moves through the weighing area with the movement of the conveyor belt 18; this process simulates the actual situation of coal passing through the belt scale;

[0029] During the simulation, the operator will observe and record the weighing results of the coal feeder belt scale and compare them with the standard values ​​to determine the accuracy and stability of the belt scale; if the weighing results are found to be inaccurate or unstable, the operator can recalibrate by adjusting the number and position of the counterweights 8;

[0030] This calibration method achieves accurate calibration of the belt scale by simulating the movement of the calibration trolley 20 and the counterweight 8, thereby improving the convenience and flexibility of calibration; this calibration device and operating method can effectively ensure the accuracy and stability of the belt scale and meet the needs of the production process.

[0031] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the connecting body includes: a group of side plates 9 symmetrically arranged on the outside of the support platform 1; a screw rod 10 rotating between the two side plates 9; a nut block 11 is threadedly engaged on the screw rod 10, and the nut block 11 is slidably engaged with the outer wall of the support platform 1.

[0032] In this embodiment, when the screw rod 10 rotates, it will drive the nut block 11 to move horizontally on the screw rod 10. Since there is a sliding fit between the nut block 11 and the support platform 1, this fit plays a guiding role, ensuring that the nut block 11 and the supporting shell 2 connected thereto can move synchronously and stably. This design improves the convenience and accuracy of increasing and decreasing the counterweight.

[0033] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the connection body further includes: a first motor 12 disposed on the outside of the side plate 9 , and the first motor 12 is fixedly connected to the end key of the screw rod 10 .

[0034] In this embodiment, when the first motor 12 is started, its output torque is directly transmitted to the screw rod 10 through a key-fixed connection. Since the key connection has the fixity and torque transmission capability, the first motor 12 can effectively drive the screw rod 10 to rotate.

[0035] In a further preferred embodiment of the present invention, Figure 2-4 As shown, the support shell 2 is arranged above the nut block 11 and rotatably cooperates therewith, and a second motor 13 is arranged on the bottom side of the nut block 11 , and the output end of the second motor 13 is fixedly connected to the end key of the support shell 2 .

[0036] In this embodiment, the second motor 13 is used to drive the support shell 2 to rotate. Through its power output, the support shell 2 can rotate at an angle when needed. This design allows the support shell 2 to adjust its position more flexibly, making it easier for the clamp 6 to grab the counterweight 8.

[0037] In a further preferred embodiment of the present invention, Figure 4 As shown, a screw rod 14 is rotatably engaged inside the support shell 2, and a connecting block 15 is threadedly engaged on the screw rod 14. The connecting block 15 is slidably engaged with the inner wall of the support shell 2, and one end of the connecting block 15 extends to the outside of the support shell 2 and is fixedly connected to the receiving plate 3.

[0038] In this embodiment, when the screw rod 14 rotates, the threaded cooperation between it and the connecting block 15 will drive the connecting block 15 to move longitudinally and horizontally in the axial direction of the screw rod 14. Since a sliding cooperation is achieved between the connecting block 15 and the inner wall of the support shell 2, this cooperation plays a guiding and limiting role, ensuring the stability and accuracy of the connecting block 15 during the movement. Therefore, through the rotation of the screw rod 14, the connecting block 15 can move longitudinally and horizontally, thereby realizing the height adjustment of the receiving plate 3. This design allows the height of the receiving plate 3 to be precisely adjusted as needed to meet different work requirements.

[0039] In a further preferred embodiment of the present invention, Figure 4 As shown, a third motor 16 is disposed on the top of the support shell 2 , and an output end of the third motor 16 is fixedly connected to an end key of the screw rod 14 .

[0040] In this embodiment, the third motor 16 is started to drive the screw rod 14 to rotate, and then drives the connecting block 15 to move longitudinally and horizontally along the axial direction of the screw rod 14 through thread engagement.

[0041] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of supporting rollers 17 are rotatably mounted inside the support platform 1, and the plurality of supporting rollers 17 are connected to each other through a chain wheel set. A fourth motor 23 is arranged on the outer side of the support platform 1, and the output end of the fourth motor 23 is fixedly connected to the end key of one of the supporting rollers 17. The same conveyor belt 18 is arranged on the plurality of supporting rollers 17, and a weighing sensor 19 is arranged on the bottom side of the conveyor belt 18.

[0042] In this embodiment, the fourth motor 23 starts to drive the supporting rollers 17 connected thereto to rotate; since the supporting rollers 17 are connected to each other through the chain wheel set, when one supporting roller 17 starts to rotate, the chain wheel set ensures that the other supporting rollers 17 also rotate synchronously; this synchronous rotation ensures that the conveyor belts 18 on all supporting rollers 17 can run evenly and stably;

[0043] A conveyor belt 18 is provided on the supporting rollers 17. The conveyor belt 18 spans across all the supporting rollers 17 and is closely attached to their surfaces. When the supporting rollers 17 rotate, they jointly drive the conveyor belt 18 to circulate above the supporting rollers 17, thereby realizing the transmission of materials.

[0044] When the material is placed on the conveyor belt 18, the weight of the material will be evenly distributed on the conveyor belt 18 and transmitted to the supporting roller 17 through the belt; at this time, since a weighing sensor 19 (L6A) is provided on the bottom side of the conveyor belt 18, the weight of the material will act on the weighing sensor 19, thereby causing it to generate an electrical signal corresponding to the weight.

[0045] In a further preferred embodiment of the present invention, Figure 1 As shown, a calibration trolley 20 is provided on the conveyor belt 18 , and a plurality of counterweight grooves 21 are provided on the top of the calibration trolley 20 .

[0046] In this embodiment, after the calibration trolley 20 is placed on the conveyor belt 18, the counterweights 8 can be selectively added or removed from the counterweight slot 21 as needed to simulate different material weights; once the counterweight is completed, the conveyor belt 18 can be started to move the calibration trolley 20 on the belt; at this time, the total weight of the calibration trolley 20, including the weight of the trolley itself and the weight of the counterweights 8, will act on the conveyor belt 18 and be evenly transferred to the supporting rollers 17 below through the belt; since the supporting rollers 17 are connected to the weighing sensors 19, the load changes of these supporting rollers 17 will be detected by the weighing sensors 19 and converted into corresponding electrical signals; this signal can then be captured and processed by the control console 22 for calibrating and verifying the measurement accuracy of the system; in this way, it can be ensured that the conveyor belt 18 system can work accurately and reliably during the actual material transmission and weighing process.

[0047] In a further preferred embodiment of the present invention, Figure 1 As shown, a control console 22 is disposed on the outer side of the support platform 1 , and the control console 22 is electrically connected to the weighing sensor 19 and the adjustment mechanism.

[0048] In this embodiment, the operator can set parameters or issue instructions on the console 22 as needed. The console 22 will convert these instructions into electrical signals and transmit them to the adjustment mechanism through an electrical connection. After receiving the electrical signals, the adjustment mechanism will perform corresponding actions according to the instructions.

[0049] Working principle: The support table 1 serves as the foundation of the entire calibration device, firmly supporting and fixing the connecting body and the adjustment mechanism; during the calibration process, the calibration trolley 20 is placed on the conveyor belt 18, and the fourth motor 23 is started to drive the supporting roller 17 connected to it to rotate; since the supporting rollers 17 are connected to each other through the chain wheel set, when one supporting roller 17 starts to rotate, the chain wheel set will ensure that the other supporting rollers 17 also rotate synchronously and smoothly; this synchronous rotation ensures that the conveyor belts 18 on all supporting rollers 17 can run evenly and stably; the conveyor The belt 18 spans across all the supporting rollers 17 and is in close contact with their surfaces; when the supporting rollers 17 rotate, they jointly drive the conveyor belt 18 to perform a circular motion above the supporting rollers 17, thereby achieving stable transmission of the material; when the material is placed on the conveyor belt 18, the weight of the material is evenly distributed on the conveyor belt 18 and is transmitted to the supporting rollers 17 through the belt; at this time, since a high-precision weighing sensor 19 is provided on the bottom side of the conveyor belt 18, the weight of the material acts on the counterweight 8, thereby causing it to generate an electrical signal that accurately corresponds to the weight;

[0050] Secondly, the third motor 16 starts to drive the screw rod 14 to rotate. When the screw rod 14 rotates, it drives the connecting block 15 to perform precise longitudinal horizontal movement in the axial direction of the screw rod 14; since the connecting block 15 and the inner wall of the supporting shell 2 are slidably matched, this match plays a precise guiding and limiting role, ensuring the stability and accuracy of the connecting block 15 during the movement; therefore, through the rotation of the screw rod 14, the connecting block 15 can move longitudinally and horizontally, thereby realizing the height adjustment of the receiving plate 3. This design enables the height of the receiving plate 3 to be accurately adjusted according to actual needs to meet different work requirements;

[0051] When the first motor 12 is started, it is directly and stably transmitted to the screw rod 10 through a key fixed connection, ensuring that the first motor 12 can effectively drive the screw rod 10 to rotate; when the screw rod 10 rotates, it drives the nut block 11 to move accurately horizontally on the screw rod 10; since the nut block 11 and the support platform 1 are slidably matched, this match plays a precise guiding role, ensuring that the nut block 11 and the supporting shell 2 connected thereto can move synchronously and stably, greatly improving the convenience and accuracy of increasing and decreasing the counterweight;

[0052] The second motor 13 is specially used to drive the support shell 2 to rotate. The support shell 2 can realize flexible angle rotation, which further facilitates the gripper 6 to grab the counterweight 8. After the gripper 6 successfully grabs the counterweight 8, it is placed in the counterweight slot 21 of the calibration trolley 20. Then, the calibration trolley 20 moves smoothly through the weighing area with the movement of the conveyor belt 18. This process highly simulates the actual situation of coal passing through the belt scale.

[0053] During the simulation, the operator will carefully observe and record the weighing results of the coal feeder belt scale, and compare them with the standard values ​​to determine the accuracy and stability of the belt scale. If the weighing results are found to be deviated or unstable, the operator will respond quickly by adjusting the number and position of the counterweights 8 and recalibrating until a satisfactory calibration effect is achieved.

[0054] This calibration method cleverly achieves accurate calibration of the belt scale by simulating the movement of the calibration trolley 20 and the counterweight 8, which not only improves the convenience of calibration, but also greatly enhances the flexibility of calibration; this calibration device and operation method can effectively ensure the accuracy and stability of the belt scale, thereby meeting the stringent requirements in the production process.
