Array-type belt scales are usually calibrated using weights, which requires personnel to place multiple (e.g., 32, each weighing 25kg) weights on the scale beam. This not only takes a long time to calibrate and requires a lot of labor, but also poses safety risks during the handling of the weights. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the above-mentioned problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides a belt conveyor device with belt scale calibration function, comprising: two weight bars;

[0005] Two bar weight bases are provided, with each bar weight corresponding to a bar weight. The bottom of the bar weight base is connected to the weighing bar of the belt scale to be calibrated, and the top of the bar weight base is provided with a V-shaped groove for supporting the bar weight.

[0006] Multiple lifting components are respectively located at the ends of the bar; the lifting components include a power unit and a lifting part; the lifting part is connected to the output shaft of the power unit to drive the lifting part to move up and down; the top of the lifting part is provided with a slot, and the end of the bar is located in the slot.

[0007] In one embodiment of this utility model, the same end of the two bar codes shares a lifting component, and the top of the lifting component has two slots.

[0008] In one embodiment of this utility model, the slot is a U-shaped structure.

[0009] In one embodiment of this utility model, the bar weight base includes a base body and a support member connected to the top of the base body; the bottom of the base body is provided with a U-shaped groove, and the bottom of the U-shaped groove is provided with at least one connecting hole group along its extension direction. The connecting hole group includes two coaxial connecting holes, which are respectively provided on the two side walls of the U-shaped groove; the U-shaped groove is engaged with the top and both sides of the weighing bar, and the two connecting holes of the connecting hole group are connected by bolts, with the bolts located abutting against the bottom of the weighing bar; a V-shaped groove is provided on the top of the support member, and the extension direction of the V-shaped groove is perpendicular to the extension direction of the U-shaped groove.

[0010] In one embodiment of this utility model, the two ends of the bar are provided with grooves that cooperate with the slot.

[0011] In one embodiment of this invention, the length of the bar is greater than the width of the belt support. In another embodiment of this invention, the power unit is an electric push rod.

[0012] In one embodiment of this utility model, the output shaft of the power unit and the lifting component are connected and fixed by a pin.

[0013] This utility model also provides a belt conveyor device, including:

[0014] A belt conveyor assembly, including a belt support and a belt movably connected above the belt support;

[0018] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0019] The belt scale calibration mechanism and belt conveyor device described in this utility model, when calibration is required, use a lifting component to lower the weight bar until it falls into the V-groove. The lifting component continues to descend until it detaches from the weight bar, thus calibrating the belt scale. When calibration is not required, the power unit drives the lifting component to rise, lifting the weight bar and moving it away from the belt, thus eliminating the need for normal belt transport. Therefore, this application can achieve automated calibration directly through the power unit when calibration is needed, eliminating the need for manual weight handling, improving calibration efficiency, reducing labor costs, and eliminating safety risks.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0034] Reference Figures 1-7 As shown, this utility model embodiment provides a belt conveyor device, including:

[0035] The belt conveyor assembly 100 includes a belt support 110 and a belt 120 movably connected above the belt support 110; the belt 120 is movably connected to the belt support 110 via a belt idler 130.

[0036] Multiple belt scales 200 to be calibrated are spaced apart along the transmission direction of the belt 120; the belt scales 200 to be calibrated are connected to the belt support 110; the belt scales 200 to be calibrated include a belt scale body 210 and scale bars 220 connected to both sides of the belt scale body 210; in some embodiments, there are four scale bars 220, which are located in front, behind, left and right of the belt scale body 210.

[0037] Multiple belt scale calibration mechanisms 300 are provided, each corresponding to a belt scale 200 to be calibrated. Each calibration mechanism 300 includes two weight bars 310, two weight bar bases 320, and multiple lifting components 330. The weight bar bases 320 correspond to the weight bars 310. The bottom of each weight bar base 320 is connected to the weighing rod 220 of the belt scale 200 to be calibrated, and the top of each base has a V-groove 321 for supporting the weight bars 310. Multiple lifting components 330 are respectively located at the ends of the weight bars 310. Each lifting component 330 includes a power unit 331 and a lifting element 332. The lifting element 332 is connected to the output shaft of the power unit 331 to drive the lifting element 332 to move up and down. The top of the lifting element 332 has a slot 333, in which the ends of the weight bars 310 are located.

[0038] Among them, the bar weight 310 of the belt scale calibration mechanism 300 is located above the belt 120; the bar weight base 320 of the belt scale calibration mechanism 300 is connected to the weighing bar 220; and the power unit 331 of the belt scale calibration mechanism 300 is connected to the belt bracket 110.

[0039] Specifically, when calibration is required, this embodiment uses the lifting component 330 to lower the bar weight 310 until it falls into the V-groove 321. The lifting component 330 continues to descend until it detaches from the bar weight 310, thus enabling calibration of the belt scale 200. When calibration is not required, the power unit drives the lifting component 332 to rise, lifting the bar weight 310 and moving it away from the belt 120, thus eliminating the need for normal transport of the belt 120. Therefore, this application can achieve automated calibration directly through the power unit 331 when calibration is needed, without the need for manual handling of the bar weight 310, improving calibration efficiency, reducing labor costs, and eliminating safety risks.

[0040] Furthermore, the two bar weights 310 share a single lifting component 330 at the same end, and the top of the lifting component 332 has two slots 333. That is, there are two lifting components 330, each located at one end of the bar weight 310. Specifically, in this embodiment, the two bar weights 310 can share a single lifting component 330. This ensures the synchronicity of the lifting of the two bar weights 310, thereby guaranteeing operational stability and preventing asynchrony from affecting the accuracy and precision of the correction. It also reduces the number of power units 331, lowering costs.

[0041] Because the weight 310 is relatively heavy, if it falls, it could damage the conveyor belt 120 or the product, or even injure or kill the operator. Therefore, to solve this problem, the slot 333 in this embodiment is a U-shaped structure. Specifically, the U-shaped structure design limits the weight 310 as it enters the U-shaped structure, preventing it from falling off during lifting and lowering, thus ensuring the safety of the equipment and the operator. Furthermore, the U-shaped structure guides the weight 310 as it enters the structure, allowing it to enter quickly.

[0042] Furthermore, the bar weight base 320 includes a base body 322 and a support member 323 connected to the top of the base body 322; the bottom of the base body 322 is provided with a U-shaped groove 324, and the bottom of the U-shaped groove 324 is provided with at least one connecting hole group 325 along its extension direction. The connecting hole group 325 includes two coaxial connecting holes, which are respectively provided on the two side walls of the U-shaped groove 324; the U-shaped groove 324 is engaged with the top and both sides of the weighing rod 220, and the two connecting holes of the connecting hole group 325 are connected by bolts, with the bolts located abutting against the bottom of the weighing rod 220; a V-shaped groove 321 is provided on the top of the support member 323, and the extension direction of the V-shaped groove 321 is perpendicular to the extension direction of the U-shaped groove 324. Specifically, the structure of this embodiment is simple and convenient for installing the bar weight base 320 on the weighing rod 220 of the belt scale 200 to be calibrated within the narrow installation space of the belt conveyor 120.

[0043] Furthermore, the two ends of the bar 310 are provided with grooves 311 that cooperate with the slot 333. Specifically, in this embodiment, the grooves 311 can cooperate with the slot 333, thereby limiting the movement of the bar 310 in its length direction during the lifting process after it is placed on the lifting component 332, thus ensuring the stability of the lifting.

[0044] Furthermore, the length L of the bar bracket 310 is greater than the width B of the belt support 110. In some embodiments, the bar bracket 310 can be customized according to the dimensions (length) of the belt support 110. Specifically, in order to facilitate the quick installation of the lifting assembly 330 on the belt support 110, the lifting assembly 330 is installed on the outside of the belt support 110. Therefore, in order to avoid the lifting assembly 330 from interfering with other components of the belt 120 conveying device while still being able to drive the bar bracket 310 to move up and down, the length of the bar bracket 310 needs to be designed to be greater than the width of the belt support 110.

[0045] Furthermore, the lifting assembly 330 also includes a connecting component for connecting the power unit 331 and the belt support 110. The connecting component includes a housing 340 and a back plate 350 connected to the top of one side of the housing 340. The power unit 331 is placed in the housing 340, and the back plate 350 is bolted to the outside of the belt support 110. Specifically, the connection structure of this embodiment is stable and reliable. Placing the power unit 331 in the housing 340 can protect the power unit 331 and prevent it from being bumped during on-site work, thus affecting its lifespan.

[0046] Furthermore, the power unit 331 is an electric linear actuator; for example, the power unit 331 uses a DC electric linear actuator with an output of DC24V and a speed of 60mm / s. Specifically, the electric linear actuator does not require the use of liquids or gases, thus eliminating the problem of hydraulic oil or gas leakage, reducing environmental pollution, and better meeting energy-saving requirements. In addition, it has low maintenance costs and is easy to install and maintain.

[0047] Furthermore, the output shaft of the power unit 331 is connected and fixed to the lifting component 332 by a pin. In some possible embodiments, a sleeve 334 is provided on the outer side of the lifting component 332, and a through hole is provided on the side wall of the sleeve 334; the output shaft of the power unit 331 is inserted into the sleeve 334, and the output shaft is also provided with a through hole, and the through hole of the sleeve 334 and the through hole of the output shaft are connected by a pin. Specifically, this embodiment facilitates the installation and disassembly of the power unit 331 and the lifting component 332.

[0048] This application improves upon the original belt-driven 120 scale by enabling automatic lifting and lowering of weights and achieving one-button scale calibration. The original locking weights were not conducive to lifting, so this application uses bar weights 310. This application utilizes an electric push rod to lift and lower the bar weights 310, thereby achieving automatic scale calibration.

[0049] This application also includes electrical components, including an operation box, power supply, buttons, and relays. In some embodiments, the array belt scale has eight belt scales 200 to be calibrated arranged on a belt support 110, the belt support 110 being 1600mm wide and the belt 120 being 12mm wide. It has four up buttons (one button controls the lifting of two weights 310) and four down buttons, corresponding to eight relays. The weight base 320 is mounted on the scale bar 220, the power unit 331 is mounted on the belt support 110, and then the output shaft of the power unit 331 is connected to the lifting component 332. The electric push rod (power unit 331) is connected to the electrical components, see [link to relevant documentation]. Figure 8 When button #1 (Up) is pressed, relay #1 supplies +24V power, causing the electric push rods corresponding to weighing beam areas #1 and #2 to rise. When button #1 (Down) is pressed, relay #2 outputs -24V, causing the electric push rods in weighing beam areas #1 and #2 to fall onto weighing beam 220, initiating calibration. This process is repeated by pressing buttons #2 (Up), #3 (Up), and #4 (Up), which raise and lower the electric push rods accordingly. When all electric push rods are lowered and all weights 310 are on weighing beam 220, calibration is performed, and the device is in calibration mode. When all electric push rods are raised, the belt conveyor is in normal operation.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
