[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a belt scale limiting device, such as... Figure 1-4 As shown, the belt scale limiting device includes: a mounting frame 1 installed on the belt scale body 2; a limiting frame 3, which is installed on the top inner side of the mounting frame 1 and extends along the length direction of the mounting frame, with the bottom of the limiting frame 3 contacting the top of the belt scale body 2; a first support frame 4, which is fixed to the top of the mounting frame 1 along the width direction of the mounting frame, and a first limiting member 5 is movably installed on the top of the first support frame 4; a second support frame 6, which is installed on the top of the mounting frame 1 along the width direction of the mounting frame, and two second limiting members 7 are movably installed on the top of the second support frame 6; and two material collection assemblies, both of which are disposed on the mounting frame 1, and the material collection assemblies are used to collect and disperse materials.

[0022] In this embodiment, the mounting frame 1 provides a solid support platform for the limiting frame 3, the first support frame 4, and the second support frame 6, ensuring the stability and reliability of the entire limiting device. The limiting frame 3 forms a physical barrier to prevent material from shifting and falling, thereby reducing the possibility of belt misalignment. The cooperation between the first support frame 4 and the first limiting component 5, and the second support frame 6 and the second limiting component 7, can divert concentrated materials and disperse material pressure to protect the belt scale body 2. The main function of the material collection component is to concentrate dispersed materials, which facilitates subsequent material distribution and solves the problem of uneven belt force caused by uneven material loading, thereby reducing the causes of belt misalignment. Uniform material distribution also helps to improve the measurement accuracy and stability of the belt scale.

[0023] In a further preferred embodiment of the present invention, the material collection assembly includes a rotating shaft 8 and an adjusting plate 9. The rotating shaft 8 is fixed to the top of the mounting frame 1, and the adjusting plate 9 is rotatably mounted on the rotating shaft 8. The adjusting plate 9 can contact the top of the belt scale body 2.

[0024] In this embodiment, the rotating shaft 8, as one of the core components of the material collection assembly, can serve as the rotation center of the adjusting plate 9, providing reliable support for the flexible rotation of the adjusting plate 9. The adjusting plate 9 can be rotated and adjusted according to the distribution of materials on the belt, thereby achieving centralized adjustment of materials. When the material distribution is uneven, the adjusting plate 9 can change the flow direction of the materials by rotating, thereby concentrating the materials and facilitating subsequent diversion.

[0025] In a further preferred embodiment of the present invention, two mounting plates 11 are mounted on the top of the mounting frame 1, and electric telescopic rods 12 are mounted on both mounting plates 11. Abutment blocks 13 are mounted on the output rods of the two electric telescopic rods 12, and the two abutment blocks 13 can respectively contact the two adjusting plates 9.

[0026] In this embodiment, the electric telescopic rod 12 has the ability to precisely control the length of the output rod, thereby achieving precise adjustment of the position of the contact block 13. When the electric telescopic rod 12 is working, the contact block 13 will move according to the change in the length of the output rod, thereby applying a certain pressure or thrust to the adjusting plate 9. This design makes the rotation and position adjustment of the adjusting plate 9 more accurate and stable. During the operation of the belt scale body 2, when it is necessary to adjust the distribution of materials, the operator can adjust the contact state between the contact block 13 and the adjusting plate 9 by controlling the telescopic action of the electric telescopic rod 12. When the contact block 13 contacts the adjusting plate 9 and applies a certain pressure, the rotation of the adjusting plate 9 will be restricted and guided to a certain extent. By precisely controlling the telescopic length and speed of the electric telescopic rod 12, the rotation angle and position of the adjusting plate 9 can be precisely adjusted.

[0027] In a further preferred embodiment of the present invention, the top of the mounting bracket 1 is provided with a plurality of scale lines 10, and the plurality of scale lines 10 are respectively surrounding the two rotating shafts 8.

[0028] In this embodiment, the scale lines 10 are arranged at certain intervals, providing clear visual reference for the operator. By observing the scale lines 10, the operator can quickly determine the current position of the adjusting plate 9 or the rotating shaft 8, thereby making more precise adjustments. When adjusting the material distribution or adjusting the position of the adjusting plate 9, the operator can first observe the scale lines 10 to determine the current reference position, and then change the position of the adjusting plate 9 by rotating the adjusting plate 9 or adjusting the electric telescopic rod 12. During the adjustment process, the operator can continuously observe the scale lines 10 to confirm the accurate position of the adjusting plate 9, thereby ensuring the uniformity of material distribution and the stability of the belt scale.

[0029] In a further preferred embodiment of this utility model, rubber blocks are installed on both of the two abutting blocks 13, and the two rubber blocks can contact the two adjusting plates 9 respectively. Multiple balls are embedded in the bottom of the two adjusting plates 9, and the multiple balls can contact the top of the limiting frame 3.

[0030] In this embodiment, the rubber block has good elasticity and wear resistance, which can provide buffering and shock absorption between the contact block 13 and the adjusting plate 9. This design helps to reduce the impact and noise caused by direct contact, while protecting the adjusting plate 9 and the contact block 13 from wear. The ball bearing design enables the adjusting plate 9 to achieve rolling contact when rotating or moving, thereby greatly reducing frictional resistance and wear. This design not only improves the flexibility and response speed of the adjusting plate 9, but also extends the service life of the equipment. When adjusting the material distribution or adjusting the position of the adjusting plate 9, the rubber block on the contact block 13 contacts the adjusting plate 9 to achieve shock absorption and noise reduction.

[0031] In a further preferred embodiment of the present invention, the first limiting member 5 and the second limiting member 7 are both composed of a limiting plate 15, a diverting plate 16 and a handle 17. The diverting plate 16 is fixed to the bottom of the limiting plate 15, and the handle 17 is installed on the top of the limiting plate 15. The first support frame 4 and the second support frame 6 are both provided with a bayonet, and the diverting plate 16 is movably installed in any one of the bayonet slots.

[0032] In this embodiment, the limiting plate 15 provides a stable support surface for fixing and installing other components. The handle 17 installed on its top facilitates the operator to grasp and move the limiting component, while the diversion plate 16 fixed at the bottom directly participates in the process of material diversion and limiting. During the operation of the belt scale body 2, the first limiting component 5 and the second limiting component 7 guide and limit the material through their diversion plate 16. The operator can adjust the position of the limiting component by grasping the handle 17 according to the distribution of the material and production needs, thereby realizing the diversion of the material.

[0033] In a further preferred embodiment of the present invention, a feeding hopper 14 is installed on the top of the mounting frame 1. The feeding hopper 14 is located directly above the belt scale body 2. The feeding hopper 14, two material collection components, the first support frame 4 and the second support frame 6 are arranged in sequence on the mounting frame 1.

[0034] In this embodiment, the main function of the feed hopper 14 is to receive and guide materials into the belt scale system, ensuring that the materials can be accurately and smoothly transported onto the belt for weighing and conveying. The belt scale body 2 is responsible for carrying and conveying the materials, and continuously and dynamically weighs the materials through the internal weighing mechanism. The materials first enter the belt scale system through the feed hopper 14. After being guided and distributed by the feed hopper 14, the materials fall evenly onto the belt. Subsequently, the belt scale body 2 continuously and dynamically weighs the materials and transmits the weighing results to the control system.

[0035] In summary, compared with related technologies, this device can concentrate the material located on the belt scale body 2 by setting up a material collection component. The concentrated material can be dispersed again by the cooperation of the first limiting component 5 and the second limiting component 7. Concentrating the material first and then dispersing the material can ensure the uniform distribution of the material. By setting up the limiting frame 3, the material can be prevented from falling from both sides of the belt scale body 2, thereby increasing the stability of material conveying.

[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
