Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, specifically to a conveyor roller structure for a high-precision belt scale. Background Technology

[0002] A belt scale is a dynamic metering device installed on a belt conveyor to continuously measure the weight of conveyed materials. It is widely used in material conveying and metering scenarios in industries such as mining, metallurgy, power, and chemicals. It can monitor the instantaneous flow rate (transport volume per unit time) and cumulative transport volume of materials in real time. Its core principle is to detect the weight of material per unit length of the belt through a detection component between the belt scale frame and the conveyor roller assembly, while a speed sensor measures the belt's running speed. After the signals from both are processed by the instrument, the instantaneous flow rate is calculated by "weight * speed", and the total transport volume is obtained after accumulation, thus realizing dynamic metering of continuously conveyed materials.

[0003] When belt scales are in use, the conveyor roller structure assists in conveying and supporting the belt. During use, the conveyor rollers are installed by bolts and bearings. This method makes the angle of the conveyor rollers relatively fixed after installation, which is not convenient to adjust the conveying status according to the actual situation, and further affects the high-precision use of the belt scale.

[0004] Therefore, there is an urgent need for a high-precision conveyor roller structure for belt scales to solve the above problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 The present invention provides a conveyor roller structure for a high-precision belt scale, including a conveyor roller component disposed above two sets of belt scale frames 1. A detection component for load identification is disposed between the conveyor roller component and the belt scale frame 1. The conveyor roller component includes a base 201, and two sets of first mounting brackets 202 are fixedly fixed on the base 201. A first conveyor roller 203 is rotatably connected between the two sets of first mounting brackets 202. A speed sensor for belt conveying speed identification is disposed on the belt scale frame 1.

[0022] It should be noted that when the belt scale is in use, the belt is supported and assisted in conveying by the first conveyor roller 203 and the two sets of second conveyor rollers 302 on the two sets of supporting conveyor components. During the conveying process, the weight of the material per unit length of the belt is detected by the detection component between the belt scale frame 1 and the conveyor roller components. At the same time, the speed sensor measures the running speed of the belt. After the two signals are processed by the instrument, the instantaneous flow rate is calculated by "weight * speed". The total conveying volume is obtained after accumulation, realizing the dynamic measurement of continuously conveyed materials.

[0023] Additionally, it is worth noting that the belt scale frame 1, speed sensor, and detection components are conventional technical components in the technical field of this application, and their working principles and operation methods will not be elaborated in detail here.

[0024] Also includes:

[0025] Symmetrically arranged on both sides of the first conveyor roller 203 are support conveying components for assisting belt support. The support conveying components include a second mounting frame 301 fixed on the base 201. Two sets of second conveyor rollers 302 for assisting support conveying are arranged between the second mounting frame 301 and the first mounting frame 202. The two sets of second conveyor rollers 302 are telescopically connected by a telescopic component. A slide plate 303 is slidably connected to the second mounting frame 301. A connecting component for auxiliary connection is arranged between the second conveyor roller 302 and the first mounting frame 202 and between the other set of second conveyor rollers 302 and the slide plate 303. A limiting component for limiting the sliding position is arranged on the slide plate 303.

[0026] It should be noted that when the belt scale is in use, the angle of the two sets of second conveyor rollers 302 on the support conveyor assembly is adjusted by the cooperation of the support conveyor assembly, telescopic assembly, connecting assembly and limiting assembly. By adjusting the angle of the second conveyor rollers 302 on both sides of the support conveyor assembly, it is convenient to adjust and control the conveying status according to the actual situation, and further facilitate the high-precision use of the belt scale.

[0027] The connecting assembly includes a mounting base 501 fixed on the first mounting frame 202 and the slide plate 303. A spherical groove 502 is provided on the mounting base 501. A ball 503 is rotatably connected inside the spherical groove 502. The ball 503 is connected and fixed to the end of the second conveying roller 302 by a connecting rod 504.

[0028] It should be noted here that the spherical groove 502, the ball 503 and the connecting rod 504 facilitate the auxiliary steerable connection.

[0029] The inner side of the spherical groove 502 and the outer side of the sphere 503 are smoothed.

[0030] It should be noted here that smoothing reduces friction, which facilitates subsequent rolling support.

[0031] Two sets of limiting components are symmetrically arranged on both sides of the slide plate 303;

[0032] It should be noted here that the limiting effect is ensured by using two sets of limiting components.

[0033] The limiting component includes a side plate 601 fixed to one side of the slide plate 303, a threaded sleeve 602 fixed on the side plate 601, and a threaded pin 603 threadedly engaged with the threaded sleeve 602.

[0034] It should be noted that after adjustment, the threaded pin 603 is rotated. During the rotation of the threaded pin 603, the mutual meshing transmission between the threaded pin 603 and the threaded sleeve 602 causes one end of the threaded pin 603 to move toward and abut against the second mounting bracket 301. Through the abutting action between one end of the threaded pin 603 and the second mounting bracket 301, the moved slide plate 303 is fixed. By fixing the slide plate 303, it is easy to maintain the adjusted state of the second conveyor roller 302.

[0035] The telescopic assembly includes an opening 401 at the end of the second conveying roller 302, a slide rod 402 slidably connected to the opening 401, and one end of the slide rod 402 being fixedly connected to the end of another set of second conveying rollers 302.

[0036] It should be noted here that the opening 401 and the slide bar 402 facilitate the retractable connection between the two sets of second conveyor rollers 302.

[0037] Working principle: When the belt scale is in use, the belt is supported and assisted in conveying by the first conveying roller 203 and the two sets of second conveying rollers 302 on the two sets of supporting conveying components. During the conveying process, the weight of the material per unit length of the belt is detected by the detection component between the belt scale frame 1 and the conveying roller components. At the same time, the speed sensor measures the running speed of the belt. After the two signals are processed by the instrument, the instantaneous flow rate is calculated by "weight * speed". The total conveying capacity is obtained by accumulating the data, thus realizing the dynamic measurement of continuously conveyed materials.

[0038] During the process of using the second conveyor roller 302 to support the belt and assist in the conveying operation, the angle of the second conveyor rollers 302 on both sides can be adjusted as needed. During the adjustment process, the slide plate 303 slides on the second mounting frame 301. Through the sliding of the slide plate 303 and the connecting component, the slide plate 303 and the second conveyor roller 302 and the first mounting frame 202 and the second conveyor roller 302 can be steered together, so that the angle of the two sets of second conveyor rollers 302 on the supporting conveying assembly can be adjusted. By adjusting the angle of the second conveyor rollers 302 on both sides of the supporting conveying assembly, it is convenient to adjust and control the conveying status according to the actual situation, and further facilitate the high-precision use with the belt scale.

[0039] After adjustment, the threaded pin 603 is rotated. During the rotation of the threaded pin 603, the mutual meshing transmission between the threaded pin 603 and the threaded sleeve 602 causes one end of the threaded pin 603 to move toward and abut against the second mounting bracket 301. Through the abutting action between one end of the threaded pin 603 and the second mounting bracket 301, the moved slide plate 303 is fixed. By fixing the slide plate 303, it is easy to maintain the adjusted state of the second conveying roller 302.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
