[0002] An electronic belt scale is a device used for dynamic weighing and speed measurement, and is widely used in industrial production, especially in the processes of transportation and material handling. It combines the functions of weight measurement and speed measurement, and can accurately monitor the material weight and belt speed in real time during the transportation process.

[0003] The existing speed measuring component of the electronic belt scale is installed on a bracket and contacts the running belt through an elastic component. By accurately measuring the speed of the belt and cooperating with a weight sensor to measure the total weight of the material passing through per unit time, the total flow rate of the conveyed material is calculated.

[0004] However, when materials with a large difference in conveying weight are transported in different areas of the belt, the belt tension is uneven or there is a situation of different tightness in the speed measuring area, which causes fluctuations in the belt during the transmission process, causing the speed measuring component to lose effective contact with the belt at some moments, resulting in the situation that the speed measuring component is in the air on the belt, thus affecting the accuracy of the speed measuring component.

[0020] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The speed measuring device for an electronic belt scale according to an embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0022] As Figures 1-3 shown, the speed measuring device for an electronic belt scale according to an embodiment of the present utility model may include a belt scale body 1, a weight measuring component 2, a speed measuring component 3, and a belt leveling component 4.

[0023] Among them, the belt weigher body 1 may include a bracket 10, conveying rollers 11 and a belt 12. Among them, an installation frame 100 is provided on the bracket 10, and a support plate 1000 is provided on the installation frame 100; the conveying rollers 11 are respectively rotatably arranged on the bracket 10, and the belt 12 is rotatably sleeved on the conveying rollers 11.

[0024] In an embodiment of the present application, the belt weigher body 1 is used to convey materials. The materials are continuously placed on the belt 12. A motor (not shown in the figure) rotates to drive the conveying rollers 11 to rotate, and the conveying rollers 11 drive the belt 12 to rotate, so as to convey the materials on the belt 12.

[0025] The weight measuring assembly 2 is slidably arranged on the installation frame 100 and abuts against the top of the belt 12.

[0026] In an embodiment of the present application, the weight measuring assembly 2 is used to measure the weight of the materials on the running belt 12, so as to realize the weight measurement of the materials during transportation.

[0027] It should be noted that the top of the belt 12 described in this embodiment refers to the part of the belt 12 on the conveying roller 11 after the belt 12 is sleeved on the conveying roller 11, which is the top of the belt 12. And through the abutment of the weight measuring assembly 2 with the top of the belt 12, the weight measurement of the materials during transportation can be realized.

[0028] The speed measuring assembly 3 is arranged on the support plate 1000.

[0029] In an embodiment of the present application, the speed measuring assembly 3 is used to detect the speed of the belt 12, so that through the cooperation with the weight measuring assembly 2, the weight of the materials and the speed of the belt 12 during transportation can be monitored in real time and accurately.

[0030] The belt flattening assembly 4 may include an adjusting mechanism 40, two upper flattening rollers 41, two linkage mechanisms 42 and two lower flattening rollers 43.

[0031] Among them, the adjusting mechanism 40 is arranged on the support plate 1000. The two upper flattening rollers 41 are respectively rotatably arranged on both sides of the adjusting mechanism 40 and abut against one side of the bottom of the belt 12. The speed measuring assembly 3 is located between the two upper flattening rollers 41 and abuts against one side of the bottom of the belt 12. One ends of the two linkage mechanisms 42 are respectively slidably connected to the corresponding upper flattening rollers 41, the other ends of the linkage mechanisms 42 are respectively rotatably connected to the corresponding lower flattening rollers 43, and the linkage mechanisms 42 are rotatably connected to the bracket 10. The two lower flattening rollers 43 respectively abut against the other side of the bottom of the belt 12.

[0032] In an embodiment of the present application, the adjusting mechanism 40 is used to adjust the tension of the belt 12 between the upper flattening roller 41 and the lower flattening roller 43, so as to ensure the flatness of the belt 12 between the two upper flattening rollers 41.

[0033] It should be noted that the distance between the two lower flat rollers 43 described in this embodiment is greater than the distance between the two upper flat rollers 41, so that the two upper flat rollers 41 can press down the belt 12 within the range of the two lower flat rollers 43, and can abut and flatten the belt 12, so that the speed measuring component 3 can measure on the abutted and flattened belt 12, thereby ensuring the accurate measurement of the speed measuring component 3.

[0034] Specifically, in the actual operation process, the relevant staff operates the adjustment mechanism 40 to rotate downward, driving the upper flat roller 41 to abut against one side of the bottom of the belt 12, and the upper flat roller 41 moves downward to drive the joint control mechanism 42 to move, and the joint control mechanism 42 controls the lower flat roller 43 to move upward, so that the lower flat roller 43 abuts against the other side of the bottom of the belt 12, so that the upper flat roller 41 and the lower flat roller 43 squeeze and tension the belt 12, so that the belt 12 between the two upper flat rollers 41 is tensioned and flattened, thereby ensuring that the speed measuring component 3 measures the speed on the belt 12 flattened between the upper flat rollers 41, and will not be affected by the fluctuation of the belt 12, thereby ensuring the accurate measurement of the speed measuring component 3.

[0035] In one embodiment of the present invention, Figures 1-3 As shown, the adjustment mechanism 40 may include a fixing plate 401 , two rotating brackets 402 and an adjustment member 400 .

[0036] Among them, one end of the adjusting member 400 is threadedly connected to the supporting plate 1000, and the other end of the adjusting member 400 is fixedly connected to the fixing plate 401. Two rotating brackets 402 are respectively arranged at both ends of the fixing plate 401, and the upper flat roller 41 is rotatably connected to the corresponding rotating brackets 402.

[0037] It is understandable that, by disposing the rotating bracket 402 , the upper flat roller 41 is rotatably connected to the rotating bracket 402 , and the upper flat roller 41 is rotatably connected to the belt 12 , thereby reducing the sliding friction between the upper flat roller 41 and the belt 12 .

[0038] In one embodiment of the present invention, Figures 1-3 As shown, the adjustment member 400 may include a bolt 4000 and a rotating block 4001 .

[0039] The bolt 4000 is threadedly connected to the support plate 1000 , one end of the rotating block 4001 is rotatably connected to the bolt 4000 , and the other end of the rotating block 4001 is fixedly connected to the fixed plate 401 .

[0040] It can be understood that, by setting the rotating block 4001 and the bolt 4000 to be rotatably connected, when the bolt 4000 rotates downward to adjust the upper flat roller 41, the upper flat roller 41 does not rotate along with the rotation of the bolt 4000, thereby facilitating the relevant staff to debug the device.

[0041] In one embodiment of the present utility model, as Figures 1-3 shown, the joint control mechanism 42 may include a connecting plate 420, a joint control plate 421 and a connecting rod 422.

[0042] Wherein, one end of the connecting plate 420 is connected to the rotating bracket 402, and a limit bolt 4200 is provided at the other end of the connecting plate 420. A sliding groove 4210 is formed at one end of the joint control plate 421, and the limit bolt 4200 is slidably arranged in the sliding groove 4210. The other end of the joint control plate 421 is connected to the lower flat roller 43. One end of the connecting rod 422 is connected to the middle of the joint control plate 421, and the other end of the connecting rod 422 is rotatably connected to the bracket 10.

[0043] It should be noted that the joint control plate 421 described in this embodiment is arc-shaped, so as to realize the lifting control of the lower flat roller 43 by the joint control plate 421.

[0044] It can be understood that through the arrangement of the connecting rod 422, the joint control plate 421 can be rotatably connected to the rotating bracket 402.

[0045] It can be understood that through the arrangement of the connecting plate 420, when the bolt 4000 rotates downward to control the downward movement of the rotating bracket 402 and the upper flat roller 41, the connecting plate 420 is driven to move downward. Through the arrangement of the limit bolt 4200 sliding in the sliding groove 4210, the connecting plate 420 presses down to control the rotation of the joint control plate 421, so as to drive the lower flat roller 43 to lift and abut against the other side of the bottom of the belt 12, thereby realizing the tensioning of the belt 12.

[0046] In one embodiment of the present utility model, as Figures 1-3 shown, the speed measuring assembly 3 may include an elastic support frame 30, a speed measuring wheel 31 and a speed sensor 32.

[0047] Wherein, the elastic support frame 30 is arranged on the support plate 1000;

[0048] The speed measuring wheel 31 is rotatably arranged on the elastic support frame 30. The speed measuring wheel 31 is located between the two upper flat rollers 41 and abuts against one side surface of the bottom of the belt 12;

[0049] The speed sensor 32 is arranged on the elastic support frame 30 and is connected to the speed measuring wheel 31.

[0050] It should be noted that the speed sensor 32 described in this embodiment is electrically connected to the speed measuring wheel 31. The speed sensor 32 and the weight measuring assembly 2 transmit the measured signals to the display panel of the controller (not shown in the figure), so as to display the real-time conveying situation of the material.

[0051] It can be understood that by arranging the speed measuring wheel 31 between the two upper flat rollers 41, it is possible to prevent the large fluctuations of the belt 12 from causing the speed measuring assembly 3 to become airborne on the belt 12. Moreover, through the arrangement of the elastic support frame 30, it is ensured that the speed measuring wheel 31 is not affected by small-amplitude vibrations and continuously abuts against the belt 12, thereby ensuring the accuracy of the speed measuring assembly 3.

[0052] Specifically, during the actual operation, the relevant staff operate the bolt 4000 to rotate downward, driving the rotating bracket 402 and the upper flat roller 41 to abut against one side of the bottom of the belt 12, and driving the connecting plate 420 to move downward. Through the arrangement of the limit bolt 4200 sliding in the chute 4210, the connecting plate 420 presses down to control the rotation of the control linkage plate 421, thereby driving the lower flat roller 43 to lift and abut against the other side of the bottom of the belt 12, so that the lower flat roller 43 abuts against the other side of the bottom of the belt 12, so that the upper flat roller 41 and the lower flat roller 43 squeeze and tension the belt 12, making the belt 12 between the two upper flat rollers 41 taut and flat. In this way, it is ensured that the speed measuring wheel 31 measures the speed on the flat belt 12 between the upper flat rollers 41 and is not affected by the fluctuations of the belt 12, thereby ensuring the accurate measurement of the speed measuring assembly 3.

[0053] In summary, the speed measuring device of the electronic belt scale according to the embodiment of the present invention can avoid the fluctuations of the belt during the conveying of materials, thereby avoiding the situation that the speed measuring assembly becomes airborne on the belt, and thus ensuring the accuracy of the speed measuring assembly.
