Description

Technical Field

[0001] The utility model relates to the technical field of weighing, in particular to a fully suspended array scale. Background Art

[0002] An electronic belt scale is a weighing instrument that can dynamically and real-time weigh bulk materials transported by a conveyor, and has been widely used in fields such as mines, ports, metallurgy, tobacco, and logistics.

[0003] At present, the weighing unit of the traditional array scale adopts a scale frame structure with one weighing sensor, which is a single idler (directly bearing) or two idlers (single-point suspension type). However, since there is only 1 or 2 weighing idlers, the effective weighing range is small, and it is greatly affected by the vibration and deviation of the conveyor, resulting in low metering accuracy and poor operation stability.

[0004] The foregoing description is for the purpose of providing general background information and does not necessarily constitute prior art. Summary of the Utility Model

[0005] The main object of the utility model is to provide a fully suspended array scale, which lengthens the weighing range and improves the weighing accuracy.

[0006] To achieve the above object, the utility model provides a fully suspended array scale, including:

[0007] A support platform;

[0008] A conveying member for conveying materials;

[0009] At least two weighing units, which are arranged on the support platform at intervals along the length direction of the support platform, and each weighing unit includes a roller assembly and a weighing assembly;

[0010] The roller assembly includes a roller, the roller abuts against the conveying member, and the conveying member is configured to move along the length direction of the support platform;

[0011] The weighing assembly includes a weighing sensor and a weighing bracket, the roller and the weighing sensor are both arranged on the weighing bracket, and the weighing sensor is used to detect the tension on the weighing bracket.

[0012] The beneficial effect of the utility model is that through the setting of multiple weighing units, based on the principle of lengthening the weighing range, the influence of the change of the tension of the conveying member on the metering error is reduced, the metering error can reach ±0.1%; the long-term stability can reach ±0.2%; thereby improving the weighing accuracy.

[0013] On the basis of the above technical solution, the utility model can be further improved as follows.

[0014] In some alternative embodiments, the fully suspended array scale further includes at least two meters, which are electrically connected to the load cells;

[0015] The number of meters matches the number of weighing units to count the detection signals of the load cells in each weighing unit.

[0016] It should be noted that by introducing meters, electrically connecting them to the load cells, and having a matching number design, the accuracy, real-time performance, reliability, and flexibility of the fully suspended array scale system are further improved.

[0017] In some alternative embodiments, the rolling direction of the idler is matched with the moving direction of the conveying member.

[0018] It should be noted that the rolling direction of the idler is matched with the moving direction of the conveying member, enabling the conveying member to roll smoothly on the idler during movement, reducing friction and wear. The energy loss caused by excessive friction is reduced, ensuring that the conveying member remains stable during movement without deviation or jitter. This not only extends the service life of the idler and the conveying member but also reduces the frequency of maintenance and replacement, saving costs.

[0019] In some alternative embodiments, there are at least four load cells;

[0020] At least two load cells are arranged at intervals along the length direction of the weighing bracket, where the length direction of the support platform matches the length direction of the weighing bracket.

[0021] It should be noted that by arranging multiple load cells at intervals on the weighing bracket, the weight of the material can be more evenly distributed and detected, avoiding overloading or uneven stress on a single sensor.

[0022] It can effectively reduce the influence caused by single-point weighing error, thereby improving the overall weighing accuracy, helping to extend the service life of the load cells, and improving the reliability of the system.

[0023] In some alternative embodiments, the at least four load cells include a first load cell, a second load cell, a third load cell, and a fourth load cell;

[0024] Among them, the first load cell and the second load cell form a first load cell group, and the first load cell and the second load cell are arranged at intervals along the width direction of the weighing bracket;

The actual product of the present utility model has 4 weighing unit groups, that is, it has 16 weighing sensors. That is, 4 groups of 0.5 - level fully suspended array scales have 16 weighing sensors and 16 acquisition channels. Each acquisition channel processes the signal of 1 weighing sensor, which can realize the real - time monitoring of the working state of each weighing sensor and ensure accurate measurement.

[0028] In some alternative embodiments, the weighing bracket includes a base and a support beam. The support beam is arranged on the base and extends along the width direction of the weighing bracket;

[0029] The weighing sensors are arranged inside the support beam.

[0030] It should be noted that the design of the base and the support beam provides a solid foundation and support, making the weighing bracket more stable when bearing the weight of materials, reducing failures and errors caused by unstable mechanical structures. The weighing sensors are arranged on the support beam, which can better protect the sensors from external impacts and interferences, and improve the overall reliability of the system.

[0031] In some alternative embodiments, the weighing sensor has an installation surface facing the support beam, and the support beam is a hollow structure;

[0032] It further includes a connecting piece. The connecting piece is arranged on the installation surface and extends along the support beam. Installation holes are formed on the support beam, and connection holes are formed on the base. The connecting piece passes through the installation holes and the connection holes to connect the weighing sensor to the base and is located inside the support beam.

[0033] It should be noted that the design of the connecting piece makes the installation process of the weighing sensor simpler and faster, greatly simplifies the installation steps, and saves time and labor costs.

[0034] In some alternative embodiments, it further includes a cover plate. One end of the weighing sensor is connected to the cover plate, and the other end of the weighing sensor is connected to the connecting piece;

[0035] The shape of the cover plate matches the shape of the installation hole and seals the installation hole.

[0036] In some alternative embodiments, the base includes at least two first vertical beams and a first cross - beam. The at least two first vertical beams are arranged at intervals, and the first cross - beam is arranged between two adjacent first vertical beams;

[0037] The support beam is arranged on the first vertical beam.

[0038] It should be noted that the combined design of the first vertical beam and the first cross beam provides a strong frame structure. The first vertical beams are arranged at intervals, which can effectively disperse and bear the weight of the material, while the first cross beam provides additional support and stability between two adjacent first vertical beams. The overall structure is more stable, reducing deformation or vibration caused by uneven stress.

[0039] In some alternative embodiments, it includes at least one of the following:

[0040] The idler assembly further includes an idler bracket, the idler bracket is arranged on the weighing bracket, and the idler rolls on the idler bracket;

[0065] Currently, the weighing unit of the traditional array scale adopts a scale frame structure with one weighing sensor, which is a single idler (direct bearing) or two idlers (single-point suspension). However, since there is only 1 or 2 weighing idlers, the effective weighing range is small, and it is greatly affected by the vibration and deviation of the conveyor, resulting in relatively low measurement accuracy and poor operation stability.

[0066] In order to overcome the defects in the prior art, the fully suspended array scale provided by the present utility model, through the setting of multiple weighing units, based on the principle of lengthening the weighing range, reduces the influence of the change in the tension of the conveying member on the measurement error. The measurement error can reach ±0.1%; the long-term stability can reach ±0.2%; thereby improving the weighing accuracy.

[0067] The content of the present utility model will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand the content of the present utility model more clearly and in detail.

[0068] Figure 1 It is a schematic structural diagram of the first perspective of the fully suspended array scale provided by the embodiment of the present utility model. Figure 2 It is a schematic structural diagram of the second perspective of the fully suspended array scale provided by the embodiment of the present utility model. Figure 3 is Figure 2 The cross-sectional view of A-A' in Figure 4 It is a schematic structural diagram of the weighing component in the fully suspended array scale provided by the embodiment of the present utility model. Figure 5 It is an exploded view of the weighing component in the fully suspended array scale provided by the embodiment of the present utility model.

[0069] As Figures 1 to 5 shown, the embodiment of the present utility model provides a fully suspended array scale 100, including:

[0070] A support platform 110;

[0071] It should be noted that the support platform 110 serves as the basis of the fully suspended array scale 100 and is used to carry the entire weighing unit 130 and the conveying member 120.

[0072] Of course, the support platform 110 can also be a rectangular frame welded by structural steel, and the rectangular frame has a load-bearing capacity.

[0073] A conveying member 120 for conveying materials;

[0074] At least two weighing units 130, and at least two weighing units 130 are arranged on the support platform 110 at intervals along the length direction of the support platform 110. The weighing unit 130 includes a roller assembly 140 and a weighing component 150;

[0075] The roller assembly 140 includes a roller 141, and the roller 141 abuts against the conveying member 120. The conveying member 120 is configured to move along the length direction of the support platform 110;

[0076] The weighing component 150 includes a weighing sensor 151 and a weighing bracket 152. Both the roller 141 and the weighing sensor 151 are arranged on the weighing bracket 152, and the weighing sensor 151 is used to detect the tension on the weighing bracket 152.

[0077] Through the above settings, that is, through the setting of multiple weighing units 130, based on the principle of lengthening the weighing range, the influence of the tension change of the conveying member 120 on the measurement error is reduced. The measurement error can reach ±0.1%; the long-term stability can reach ±0.2%; thereby improving the weighing accuracy.

[0078] Specifically, in practical applications, the multiple weighing units 130 in the present utility model are in four groups. That is to say, the four groups of weighing units 130 are spaced apart on the support platform 110. Compared with the existing structure, the solution of the present utility model lengthens the weighing range, and thus, the measurement accuracy is improved.

[0079] Of course, specific values or quantities are not overly restricted here and can be adjusted according to the actual situation. Considering real products, the present utility model adopts a 4-group structure to weigh materials in real time.

[0080] It should be noted that the following will specifically describe each structure.

[0081] It should be noted that by spacing multiple weighing units 130 on the support platform 110, dynamic weighing of the conveyed materials can be achieved. The weighing sensor 151 can detect the weight of the materials on the conveyor 120 in real time, thereby improving the weighing accuracy. Since the conveyor 120 moves along the length direction of the support platform 110, the weighing sensor 151 can continuously monitor the materials. This continuous weighing method helps to promptly detect changes in the material weight and is applicable to production lines or conveying systems that require real-time weight monitoring.

[0082] In addition, the roller 141 in the roller assembly 140 abuts against the conveyor 120, ensuring the stability of the conveyor 120 during movement. The design of the weighing bracket 152 ensures that the weighing sensor 151 can accurately detect the tension on the weighing bracket 152, thereby improving the stability and reliability of the weighing system.

[0083] Among them, the modular design of the weighing unit 130 makes the installation and maintenance of the system more convenient. The number and spacing of the weighing units 130 can be adjusted according to actual needs to adapt to conveyed materials of different lengths and weights.

[0084] In some alternative embodiments, the full suspension array scale 100 further includes at least two meters 160, and the meters 160 are electrically connected to the weighing sensors 151;

[0085] The number of the meters 160 matches the number of the weighing units 130 to count the detection signals of the weighing sensors 151 in each weighing unit 130.

[0086] It should be noted that by introducing the meters 160 and electrically connecting them to the weighing sensors 151 with a matching number design, the accuracy, real-time performance, reliability, and flexibility of the full suspension array scale 100 system are further improved.

[0087] It should be noted that each weighing unit 130 is equipped with a corresponding meter 160, which can independently collect and process the detection signals of the weighing sensors 151. This one-to-one matching relationship ensures the accuracy of data collection and avoids signal confusion or interference. The number of meters 160 matches the number of weighing units 130, making the system have good flexibility and scalability.

[0088] In addition, through the independent statistics of the signals of the weighing sensors 151 by multiple meters 160, comprehensive data analysis of the entire conveying system can be achieved. In this way, not only can the independent data of each weighing unit 130 be obtained, but also the weight distribution and change trend of the entire conveying process can be obtained through data integration, providing data support for further optimizing the conveying and weighing systems. The meter 160 can statistically process the detection signals of the weighing sensors 151 in real time, enabling the system to monitor the conveyed materials in real time. The acquisition and processing of real-time data help to detect and respond to changes in the weight of the materials in a timely manner, improving the response speed and sensitivity of the system.

[0089] In some alternative embodiments, the rolling direction of the idler 141 matches the moving direction of the conveying member 120.

[0090] It should be noted that the rolling direction of the idler 141 matches the moving direction of the conveying member 120, enabling the conveying member 120 to roll smoothly on the idler 141 during movement, reducing friction and wear. The energy loss caused by excessive friction is reduced, ensuring that the conveying member 120 remains stable during movement and does not deviate or vibrate. This not only extends the service life of the idler 141 and the conveying member 120, but also reduces the frequency of maintenance and replacement, saving costs.

[0091] In addition, the matching rolling direction enables the conveying member 120 to move more smoothly and efficiently.

[0092] In some embodiments, there may be 3 idlers 141 provided on each weighing bracket 152. The axis of the middle idler 141 is parallel to the horizontal plane, and the centerlines of the idlers 141 on both sides are inclined with respect to the horizontal plane, so that the multiple idlers 141 form an inwardly concave structure, enabling the idlers 141 to fit with the conveying member 120 and the idlers 141 to rotate along with the transmission direction of the conveying member 120. The idlers 141 provide support for the conveying member 120 and reduce the friction during the transmission of the conveying member 120.

[0093] In some alternative embodiments, there are at least four weighing sensors 151;

[0094] At least two weighing sensors 151 are arranged on the weighing bracket 152 at intervals along the length direction of the weighing bracket 152 , wherein the length direction of the supporting platform 110 matches the length direction of the weighing bracket 152 .

[0095] It should be noted that by arranging a plurality of weighing sensors 151 at intervals on the weighing bracket 152, the weight of the material can be more evenly distributed and detected, avoiding overloading or uneven force on a single sensor.

[0096] The influence caused by single-point weighing error can be effectively reduced, thereby improving the overall weighing accuracy, helping to extend the service life of the weighing sensor 151 and improving the reliability of the system.

[0097] In addition, multiple weighing sensors 151 are arranged at intervals along the length direction of the weighing bracket 152, so that the weighing bracket 152 is more stable when subjected to force, reducing deformation or vibration caused by uneven force, thereby improving the stability and accuracy of weighing data, and multiple weighing sensors 151 provide more detection points, which can achieve more detailed real-time monitoring and data analysis. Through the comprehensive processing of multiple sensor data, the weight distribution and changes of the material can be more comprehensively understood, providing data support for optimizing the conveying and weighing system.

[0098] It should be noted that X represents the length direction of the support platform 110 and the length direction of the weighing bracket 152 .

[0099] like Figure 4 and Figure 5 As shown, in some optional embodiments, the at least four weighing sensors 151 include a first weighing sensor 1511, a second weighing sensor 1512, a third weighing sensor 1513, and a fourth weighing sensor 1514;

[0100] The first weighing sensor 1511 and the second weighing sensor 1512 form a first weighing sensor group, and the first weighing sensor 1511 and the second weighing sensor 1512 are arranged at intervals along the width direction of the weighing bracket 152;

[0101] The third weighing sensor 1513 and the fourth weighing sensor 1514 form a second weighing sensor group, and the third weighing sensor 1513 and the fourth weighing sensor 1514 are arranged at intervals along the width direction of the weighing bracket 152;

[0102] The first weighing sensor group and the second weighing sensor group are respectively arranged at intervals along the length direction of the weighing bracket 152 .

[0103] It should be noted that the settings of the first weighing sensor 1511, the second weighing sensor 1512, the third weighing sensor 1513, and the fourth weighing sensor 1514 can be understood as having 4 weighing sensors 151 in each weighing unit 130. The actual product of the present invention has 4 groups of weighing units 130, that is, there are 16 weighing sensors 151. That is, 4 groups of 0.5-level fully suspended array scales 100 have 16 weighing sensors 151 and 16 acquisition channels. Each acquisition channel processes the signal of 1 weighing sensor 151, which can realize the real-time monitoring of the working state of each weighing sensor 151 and ensure accurate measurement.

[0104] Specifically, by arranging a plurality of weighing sensors 151 at intervals in the width direction and the length direction of the weighing support 152, the weight of the material can be more evenly distributed and detected.

[0105] It should be noted that Y represents the width direction of the weighing support 152.

[0106] In some alternative embodiments, the weighing support 152 includes a base 1521 and a support beam 1522. The support beam 1522 is arranged on the base 1521 and extends along the width direction of the weighing support 152;

[0107] The weighing sensor 151 is arranged inside the support beam 1522.

[0108] It should be noted that the designs of the base 1521 and the support beam 1522 provide a solid foundation and support, making the weighing support 152 more stable when bearing the weight of the material, reducing faults and errors caused by unstable mechanical structures. The weighing sensor 151 is arranged on the support beam 1522, which can better protect the sensor from external impacts and interferences and improve the overall reliability of the system.

[0109] The weighing sensor 151 is arranged on the support beam 1522, which can detect the weight of the material more directly and accurately. The design that the support beam 1522 extends along the width direction enables the weighing sensors 151 to be evenly distributed on the entire weighing support 152, thereby improving the overall weighing accuracy.

[0110] In addition, the modular designs of the base 1521 and the support beam 1522 make the installation and maintenance of the weighing sensor 151 more convenient. The sensor can be directly fixed on the support beam 1522, simplifying the installation process and also facilitating later maintenance and replacement, reducing the maintenance cost and time.

[0111] In some embodiments, the base 1521 and the support beam 1522 can be assembled by a detachable installation method. For example, bolt connection is used, and the distance between each structure can be adjusted.

[0112] In some alternative embodiments, the load cell 151 has a mounting surface facing the support beam 1522, and the support beam 1522 is a hollow structure;

[0113] It further includes a connecting member 170, which is disposed on the mounting surface and extends along the support beam 1522. Mounting holes 15221 are formed on the support beam 1522, and connection holes are formed on the base 1521. The connecting member 170 passes through the mounting holes 15221 and the connection holes, so that the load cell 151 is connected to the base 1521 and is located inside the support beam 1522.

[0114] It should be noted that the design of the connecting member 170 makes the installation process of the load cell 151 simpler and faster, greatly simplifies the installation steps, and saves time and labor costs.

[0115] The mating design of the connecting member 170 and the connection holes ensures the firm connection between the load cell 151 and the base 1521, prevents the sensor from loosening or falling off due to vibration or external forces during use, enables the load cell 151 to better resist the influence of the external environment, such as vibration, impact, etc., improves the overall reliability and stability of the system, and ensures the safety of long-term operation.

[0116] Such as Figure 5 shown, in some alternative embodiments, it further includes a cover plate 180. One end of the load cell 151 is connected to the cover plate 180, and the other end of the load cell 151 is connected to the connecting member 170;

[0117] The shape of the cover plate 180 matches the shape of the mounting holes 15221 and seals the mounting holes 15221.

[0118] It should be noted that such a setting can make the load cell 151 stably located inside the support beam 1522, and by sealing the mounting holes 15221 with the cover plate 180, it can prevent dust from entering the support beam 1522, thereby causing damage to the load cell 151 in a long-term environment.

[0119] In some embodiments, the load cell 151 can also be installed through a snap member. Among them, the snap member can have a snap portion and an extension portion connected in sequence. The cross-sectional dimension of the snap portion is larger than that of the extension portion, so that the snap portion forms a stable snap point in the connection hole. This design ensures that the load cell 151 will not easily loosen or fall off after installation, and improves the firmness and stability of the connection.

[0120] The smaller cross-sectional dimension of the extension portion enables the snap member to easily pass through the mounting hole, while the larger cross-sectional dimension of the snap portion ensures the fixation of the snap member in the mounting hole.

[0121] In some embodiments, the buckle portion and the extension portion are connected by an integral connection method. In other embodiments, the buckle portion and the extension portion can also be connected by other connection methods. As long as the connection method can fixedly connect the buckle portion and the extension portion, the purpose of this embodiment can be achieved. Here, the connection method of the buckle portion and the extension portion is not limited.

[0122] In some alternative embodiments, the base 1521 includes a first vertical beam 15211 and a first cross beam 15212. There are at least two first vertical beams 15211, and the at least two first vertical beams 15211 are spaced apart. The first cross beam 15212 is disposed between two adjacent first vertical beams 15211;

[0123] The support beam 1522 is disposed on the first vertical beam 15211.

[0124] It should be noted that the combined design of the first vertical beam 15211 and the first cross beam 15212 provides a sturdy frame structure. The first vertical beams 15211 are spaced apart, which can effectively disperse and bear the weight of the material, while the first cross beam 15212 provides additional support and stability between two adjacent first vertical beams 15211. The overall structure is more stable, reducing deformation or vibration caused by uneven stress.

[0125] The support beam 1522 is disposed on the first vertical beam 15211, which can more directly and accurately transfer the weight of the material to the load cell 151. The sturdy structure of the base 1521 ensures the stability of the weighing bracket 152 when bearing the material, thereby improving the accuracy and reliability of the weighing data.

[0126] In some embodiments, the first vertical beam 15211 and the first cross beam 15212, and the support beam 1522 and the first vertical beam 15211 can be assembled by a detachable installation method. For example, bolt connection is used, and the distance between each structure can be adjusted.

[0127] In some alternative embodiments, it at least includes one of the following:

[0128] The roller assembly 140 further includes a roller bracket 142. The roller bracket 142 is disposed on the weighing bracket 152, and the roller 141 is rotatably disposed on the roller bracket 142;

[0129] It should be noted that the roller bracket 142 is disposed on the weighing bracket 152, making the installation of the roller 141 more stable. The roller 141 is rotatably disposed on the roller bracket 142, ensuring that the contact between the roller 141 and the conveyor 120 is smoother and more stable.

[0130] The support platform 110 includes at least two second vertical beams 111. A hook member 1523 is provided on the weighing bracket 152. The hook member 1523 has a hook portion, and the structure of the hook portion is matched with the structure of the second vertical beam 111. The hook portion is hooked on the second vertical beam 111 so that the weighing bracket 152 is connected to the support platform 110.

[0131] It should be noted that through the matching structure of the hook portion and the second vertical beam 111, the weighing bracket 152 can be firmly connected to the support platform 110, thereby improving the stability and safety of the entire structure. This design can adapt to support platforms 110 of different sizes and shapes, increasing the flexibility and adaptability of the system.

[0132] The design of the hook member 1523 enables the weighing bracket 152 to be quickly and conveniently connected to the support platform 110, reducing the installation time and complexity. This connection method makes disassembly and maintenance easier, facilitating the replacement or repair of components of the weighing bracket 152 or the support platform 110.

[0133] Exemplarily, the support platform 110 may include second vertical beams 111 that are parallel and spaced apart. The extending direction of the second vertical beams 111 is parallel to the extending direction of the conveying member 120. Specifically, the second vertical beams 111 can be cut from I-beams or channel steels.

[0134] The conveying member 120 is a belt.

[0135] It should be noted that belt transmission can cover a long transmission distance and is suitable for material transmission requirements that need to span a large space. Moreover, it can transmit various types of materials, including bulk materials, packaged materials, granular materials, etc., and has high adaptability.

[0136] The full-suspension array scale provided by the embodiment of the present utility model includes a support platform; a conveying member for conveying materials; at least two weighing units that are spaced apart along the length direction of the support platform on the support platform. The weighing unit includes a roller assembly and a weighing assembly; the roller assembly includes rollers that abut against the conveying member, and the conveying member is configured to move along the length direction of the support platform; the weighing assembly includes a weighing sensor and a weighing bracket, and both the roller and the weighing sensor are provided on the weighing bracket, and the weighing sensor is used to detect the tension on the weighing bracket.

[0137] Through the setting of multiple weighing units, based on the principle of lengthening the weighing area, the influence of the change in the tension of the conveying member on the measurement error is reduced. The measurement error can reach ±0.1%; the long-term stability can reach ±0.2%; thereby improving the weighing accuracy.
