Description

Technical Field

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

[0002] When installing a belt scale, the load cell is connected to the idler frame base in a contact manner. However, with this contact installation, the force is transmitted between the load cell and the idler frame base through a limited number of contact points. These contact points may not distribute the force evenly, resulting in some areas experiencing excessive force while others experience less force. For example, when the material is unevenly distributed on the belt, the force on the idler frame will change. However, due to the uneven force distribution at the contact points, the load cell cannot accurately detect this change, thus affecting the measurement accuracy.

[0003] Therefore, there is an urgent need for a high-precision weighing sensor mounting structure for belt scales to solve the above problems. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 The present invention provides a weighing sensor mounting structure for a high-precision belt scale, including a fixing frame 101 for mounting the weighing sensor body 102, two sets of weighing sensor bodies 102 are symmetrically fixed on the fixing frame 101, and a bearing component is provided above the weighing sensor body 102. A load-bearing beam 2 is provided between the weighing sensor body 102 and the load-bearing component. The two sets of weighing sensor bodies 102 are fixed to the bottom of the load-bearing beam 2 by threaded connection. A connecting component for auxiliary connection and fixing is provided between the load-bearing beam 2 and the load-bearing component.

[0020] It should be noted that when the load cell is installed and used on the belt scale, the cooperation between the connecting component, the bearing component, and the load-bearing beam 2 helps to form a rigid integral structure between the installed load cell body 102 and the bearing component. This rigid connection allows the bearing component to better transfer force to the load cell body 102 when bearing the weight of eccentric materials. Furthermore, due to the high stability of the rigid integral structure, the cooperative working ability between the bearing component and the load cell body 102 is enhanced. When facing eccentric material conveying, the entire structure can more stably bear the weight, reduce measurement errors caused by structural deformation or displacement, and improve the detection accuracy of the belt scale.

[0021] The load-bearing component includes a base 301, on which multiple sets of mounting brackets 302 are fixed, and on which idler rollers 303 for lifting the belt are rotatably connected;

[0022] It should be noted here that the belt and the material on the belt are supported by the base 301, the mounting frame 302 and the idler roller 303, and the belt abuts against the upper end of the idler roller 303.

[0023] It is worth noting that the base 301, mounting bracket 302 and idler roller 303 are conventional load-bearing support components on the belt scale, and will not be described in detail in this application.

[0024] Two sets of connecting components are symmetrically arranged between the base 301 and the load-bearing beam 2. The connecting components include a connecting seat 401 fixed on the load-bearing beam 2, and a pressure plate 402 is provided above the base 301. The pressure plate 402 and the connecting seat 401 are fixed together by bolts.

[0025] It should be noted here that the connection between the connecting seat 401, the pressure plate 402 and the connecting block 403 assists in the fixed installation between the base 301 and the load-bearing beam 2.

[0026] A protective cover 5 for shielding and protecting the weighing sensor body 102 is fixed on the mounting bracket 101;

[0027] It should be noted here that the protective cover 5 is used to shield and protect the weighing sensor body 102.

[0028] The load-bearing beam 2 is provided with an identification component for identifying the state of the fixed load-bearing beam 2. The identification component includes an installation groove 601 opened on the load-bearing beam 2. A bubble level 602 is fixed inside the installation groove 601 by a limiting component.

[0029] It should be noted that during the installation and fixing of the load-bearing beam 2 and the two sets of weighing sensor bodies 102, the state of the weighing sensor bodies 102 is promptly identified by the bubble level 602 installed inside the mounting groove 601 on the load-bearing beam 2, so as to avoid the load-bearing beam 2 tilting during the installation and connection process, and further facilitate more accurate rigid connection transmission in the future.

[0030] The limiting component includes two sets of clamping plates 701 disposed inside the mounting groove 601. The mounting groove 601 is provided with a telescopic component for telescopic connection of the clamping plates 701. An arc-shaped groove 702 for abutting against the outer side of the bubble level 602 is provided on the opposite side of the two sets of clamping plates 701. An inclined surface 703 for abutting against the bubble level 602 is provided on one side of the clamping plate 701.

[0031] It should be noted that: when the bubble level 602 is pushed between the two sets of clamping plates 701, the bubble level 602 abuts against the inclined surface 703 on the clamping plate 701. During the abutment, the two sets of clamping plates 701 are pushed away from each other by the force. After the bubble level 602 moves between the two sets of clamping plates 701, the telescopic component pushes the clamping plate 701 back to its original position, so that the arc groove 702 on the clamping plate 701 abuts against the bubble level 602, thus completing the clamping and installation of the bubble level 602.

[0032] The telescopic assembly includes multiple sets of sleeves 801 fixed inside the mounting groove 601. A slide rod 802 is slidably connected to the sleeve 801. One end of the slide rod 802 is fixed to the clamping plate 701. A spring 803 is sleeved on the outside of the sleeve 801. The two ends of the spring 803 are respectively connected to the inner wall of the mounting groove 601 and the clamping plate 701.

[0033] It should be noted that the sleeve 801 and the slide rod 802 facilitate the telescopic connection of the clamping plate 701, and the spring 803 pushes the clamping plate 701 back to its original position after the contraction movement.

[0034] Working principle: When the load cells are installed on the belt scale, two sets of load cell bodies 102 are fixedly installed on the mounting bracket 101. After installation, the load-bearing beam 2 is fixed between the two sets of load cell bodies 102. After the load-bearing beam 2 is fixed, the base 301 on the bearing component is connected and fixed to the load-bearing beam 2 through the connecting component. After the connection is completed, the connection and fixing effect of the connecting component, the load-bearing beam 2 and the two sets of load cell bodies 102 helps to form a rigid integral structure between the installed load cell bodies 102 and the bearing component. This rigid connection allows the bearing component to better transmit the force to the load cell bodies 102 when bearing the weight of eccentric materials. Moreover, due to the high stability of the rigid integral structure, the cooperative working ability between the bearing component and the load cell bodies 102 is enhanced. When facing the situation of eccentric material conveying, the whole structure can more stably bear the weight, reduce the measurement error caused by structural deformation or displacement, and improve the detection accuracy of the belt scale.

[0035] During the installation and fixing of the load-bearing beam 2 and the two sets of weighing sensor bodies 102, the state of the weighing sensor bodies 102 is promptly identified by the bubble level 602 installed inside the mounting groove 601 on the load-bearing beam 2, so as to avoid the load-bearing beam 2 from tilting during the installation and connection process, and further facilitate more accurate rigid connection transmission in the future.

[0036] 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.
