Description

Technical Field

[0001] This utility model relates to a weighing belt scale, belonging to the technical field of weighing belt scales. Background Technology

[0002] A belt-type dynamic weighing scale is a device used to measure the mass or weight of an object. Compared with static weighing equipment, belt-type dynamic weighing scales continuously measure the weight of an object during transportation. Its basic principle is to determine the weight of the object by detecting changes in the gravity or pressure of the object on the belt through sensors.

[0003] In existing technologies, belt-type dynamic weighing scales are generally connected in series with a conveyor line. Weighing is completed during the belt drive process as the material to be weighed is conveyed onto the weighing belt. In existing belt-type weighing scales, load cells are fixedly installed at the lower ends of the driving and driven rollers for weighing. However, because the material to be weighed is being weighed while in motion, the belt drive cannot guarantee a uniform speed, and the belt speed differs depending on whether there is a load or not. This causes the belt scale to sway back and forth, and generates torque at the load cells, resulting in unstable weighing values ​​and significant errors.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a weighing belt scale that can reduce the impact of lateral forces caused by the swaying of the belt scale, making the weighing data more accurate and extending the service life of the weighing sensor.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A weighing belt scale includes a drive roller and a driven roller, with a weighing belt wound around the drive roller and the driven roller. Support columns are provided at both ends of the drive shafts of the drive roller and the driven roller.

[0008] Each support column is equipped with external fixing plates on both the front and rear sides to limit the front and rear movement of the support column;

[0009] The bottom of the support column is provided with multiple bullseye bearings, which cooperate with a weighing sensor located on its lower side. The weighing sensor is fixedly installed on the upper surface of the bracket.

[0010] Furthermore, multiple cylindrical rollers are provided on the front and rear sides of the support column along its length, and the cylindrical rollers cooperate with the inner side of the outer fixing plate.

[0011] Furthermore, an inner baffle is provided on the inner side of the outer fixing plate, and a sliding rod is provided on the outer side of the inner baffle. The sliding rod is slidably mounted on the outer fixing plate, and a compression spring is fitted on the portion of the sliding rod located between the outer fixing plate and the inner baffle.

[0012] Furthermore, the bottom of the supporting column is provided with a base plate horizontally, the top of the weighing sensor is provided with a top plate horizontally, the bullseye bearing is installed on the base plate, and the bullseye bearing cooperates with the top plate.

[0013] Furthermore, a drive motor is installed on the active roller, and the drive motor drives the weighing belt transmission.

[0014] Furthermore, the bottom of the outer fixing plate is fixedly installed on the upper surface of the bracket.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0016] Each support column has an external fixing plate on its front and rear sides. The bullseye bearing at the bottom of the support column cooperates with the load cell located on its lower side to prevent the support column from generating lateral force on the load cell during transmission, thereby making the weighing data more accurate and extending the service life of the load cell.

[0017] The cylindrical rollers of the support column cooperate with the inner side of the inner baffle. When the support column moves back and forth, the compression spring acts as a buffer, making the transmission of heavy objects on the weighing belt more stable, thus further ensuring more accurate weighing.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1-2 As shown, this utility model provides a weighing belt scale, including a driving roller 1 and a driven roller 2, with a weighing belt 8 wound on the driving roller 1 and the driven roller 2. Support columns 3 are respectively provided at both ends of the drive shafts of the driving roller 1 and the driven roller 2.

[0025] Each support column 3 has an outer fixing plate 7 on its front and rear sides to limit the front and rear movement of the support column 3 and prevent it from moving forward or backward. The bottom of the outer fixing plate 7 is fixedly installed on the upper surface of the bracket 14.

[0026] The bottom of the support column 3 is provided with multiple bullseye bearings 10. The bullseye bearings 10 cooperate with the weighing sensors 12 located on their lower side. The weighing sensors 12 are fixedly installed on the upper surface of the bracket 14.

[0027] The outer fixing plates 7 on the front and rear sides of the support column 3 block the support column 3 to prevent the support column 3 from generating lateral force on the weighing sensor 12 during the transmission process, so as to make the weighing sensor 12 bear torque and make the measurement data inaccurate.

[0028] Multiple cylindrical rollers 4 are respectively provided on the front and rear sides of the support column 3 along its length. The cylindrical rollers 4 cooperate with the inner side of the outer fixing plate 7. This causes the support column 3 and the outer fixing plate 7 to have rolling friction, which reduces the external force on the support column 3 in the vertical direction when the support column 3 moves slightly up and down.

[0029] Furthermore, an inner baffle 5 is provided on the inner side of the outer fixing plate 7, and a sliding rod is provided on the outer side of the inner baffle 5. The sliding rod is slidably mounted on the outer fixing plate 7, and a compression spring 6 is fitted onto the portion of the sliding rod located between the outer fixing plate 7 and the inner baffle 5. The cylindrical roller 4 of the supporting column 3 cooperates with the inner side of the inner baffle 5. When the supporting column 3 moves back and forth, the compression spring 6 acts as a buffer, making the transmission of the heavy object on the weighing belt 8 more stable, thereby further ensuring more accurate weighing.

[0030] The bottom of the support column 3 is provided with a base plate 9, and the top of the weighing sensor 12 is provided with a top plate 11. The bullseye bearing 10 is installed on the base plate 9 and cooperates with the top plate 11.

[0031] The drive roller 1 is equipped with a drive motor 13, which drives the weighing belt 8 for transmission.

[0032] The specific working principle of this utility model:

[0033] The drive shafts of the active roller 1 and the passive roller 2 are respectively provided with support columns 3 at both ends. Each support column 3 is provided with an outer fixing plate 7 on its front and rear sides. The bullseye bearing 10 at the bottom of the support column 3 cooperates with the weighing sensor 12 located on its lower side to prevent the support column 3 from generating lateral force on the weighing sensor 12 during the transmission process, so as to make the weighing data more accurate and extend the service life of the weighing sensor.

[0034] An inner baffle 5 is provided on the inner side of the outer fixing plate 7, and a sliding rod is provided on the outer side of the inner baffle 5. The sliding rod is slidably mounted on the outer fixing plate 7, and a compression spring 6 is fitted on the part of the sliding rod located between the outer fixing plate 7 and the inner baffle 5. When the support column 3 moves back and forth, the compression spring 6 acts as a buffer, making the transmission of the heavy object on the weighing belt 8 more stable, thereby further ensuring more accurate weighing.
