[0030] A belt scale is a metering device for continuously and dynamically weighing solid materials conveyed by a belt. By measuring the weight of the materials on the belt and the running speed of the belt, the flow rate of the materials is calculated through calculation.

[0031] Before using the belt scale, it is necessary to calibrate the belt scale. By hanging standard weights of known weight at specific positions on the belt scale to simulate the weight of the materials, and then comparing the value displayed by the belt scale with the actual weight of the hanging weights, the accuracy of the belt scale is verified and calibrated. The existing belt scale hanging weight calibration generally uses manual hanging weights, and the workload of hanging weights is large.

[0032] To solve the above problems, the present utility model proposes a weighing idler loading device 1000, which includes a weighing idler 1, a hanging weight mechanism 2 and a lifting mechanism 3. A roller hanging rod 11 is provided on the weighing idler 1; the hanging weight mechanism 2 includes weights 21, a weight tray 21 and a connecting member 23. The weights 21 are arranged on the weight tray 21. The connecting member 23 includes a first connecting portion 231 and a second connecting portion 232 arranged in the vertical direction. The first connecting portion 231 is located above the second connecting portion 232, and the bottom end of the second connecting portion 232 is connected to the weight tray 21; the lifting mechanism 3 is arranged on one side of the weighing idler 1. The lifting mechanism 3 includes a cross bar 31 and a driving member 32. The output end of the driving member 32 is connected to the cross bar 31. The cross bar 31 is movably matched with the first connecting portion 231. The driving member 32 can drive the cross bar 31 to move up and down in the vertical direction and has a first position and a second position; when the cross bar 31 is in the first position, the cross bar 31 cooperates with the first connecting portion 231, and the weight of the weight tray 21 is borne by the cross bar 31. When the cross bar 31 is in the second position, the cross bar 31 is disengaged from the first connecting portion 231, and the second connecting portion 232 cooperates with the roller hanging rod 11, and the weight of the weight tray 21 is borne by the roller hanging rod 11.

[0033] The technical solution of the present utility model realizes the installation and adjustment of the hanging weight mechanism 2 by setting the hanging weight mechanism 2 and the lifting mechanism 3. The driving member 32 drives the cross bar 31 to move up and down to the first position and the second position. When the cross bar 31 is in the first position, it cooperates with the first connecting portion 231 to lift the weight tray 21. At this time, the weighing idler 1 is in the unloaded state. When the cross bar 31 is in the second position, the cross bar 31 is disengaged from the first connecting portion 231, and the second connecting portion 232 cooperates with the roller hanging rod 11. The weight of the weight tray 21 is borne by the roller hanging rod 11. At this time, the weighing idler 1 is in the loaded state. The cross bar 31 moves up and down to realize the switching of the weighing idler 1 between the loaded and unloaded states, realizing the automation of hanging weights, improving the efficiency of hanging weights, and reducing the labor intensity of hanging weights.

[0034] In an optional embodiment, to facilitate the installation and adjustment of the hanging weight mechanism 2, the lifting mechanism 3 further includes an annular component 24. The annular component 24 includes two U-shaped lead screws 241 and two lead screw sleeves 242. The two ends of the lead screw sleeve 242 are provided with internal threads with opposite helix directions along the axial direction. The two ends of the U-shaped lead screw 241 are provided with external threads. The internal threads at both ends of one lead screw sleeve 242 are respectively screwed with one end of the two U-shaped lead screws 241 to connect the two U-shaped lead screws 241 end to end. The annular component 24 connects the cross bar 31 and the first connecting portion 231. Please refer to Figures 1 to 3, two U-shaped lead screws 241 are connected end to end by two lead screw sleeves 242 to form an annular assembly 24. The thread directions at both ends of the lead screw sleeve 242 are opposite. On the one hand, the installation height of the connecting member 23 below the annular assembly 24 can be adjusted by simultaneously rotating the two lead screw sleeves 242, so as to adjust the installation height of the weight 21 tray. On the other hand, the detachable connection between the U-shaped lead screw 241 and the lead screw sleeve 242 also facilitates the installation connection between the annular assembly 24 and the connecting member 23. By passing the cross bar 31 through the inner hole of the annular assembly 24, the annular assembly 24 is lapped on the cross bar 31 to lift the weight 21 tray below when the weighing roller 1 unloads.

[0035] Furthermore, to ensure the stability of the connection between the annular assembly 24 and the cross bar 31, the lifting mechanism 3 further includes two locking nuts 25. The two locking nuts 25 are respectively screwed onto the cross bar 31 and are arranged on both sides of the annular assembly 24 to fix the annular assembly 24 to the cross bar 31. Please refer to Figure 1 and Figure 3 , the annular assembly 24 is lapped on the cross bar 31. The two locking nuts 25 are respectively arranged on the opposite sides of the annular assembly 24 and are screwed onto the cross bar 31 to clamp and fix the annular assembly 24 on the cross bar 31, preventing the annular assembly 24 from shaking and disengaging from the cross bar 31 during operation, and ensuring the stability of the weighing roller loading device 1000. In addition, by adjusting the position of the locking nut 25, the installation position of the annular assembly 24 on the cross bar 31 can also be adjusted.

[0036] In an alternative embodiment, to facilitate the switching between loading and unloading of the weighing roller 1, both the first connecting portion 231 and the second connecting portion 232 are annular connecting portions, and the first connecting portion 231 is fixedly connected to the second connecting portion 232. Please refer to Figure 1, the first connecting portion 231 and the second connecting portion 232 are arranged at intervals in the vertical direction. When the weighing idler 1 unloads, the upper first connecting portion 231 cooperates with the annular assembly 24, and the cross bar 31 is in the first position, and the lower weight tray 21 is lifted by the cross bar 31. When the weighing idler 1 needs to be loaded, the cross bar 31 is driven by the driving member 32 to move downward to the second position, the first connecting portion 231 is disengaged from the upper annular assembly 24, and the lower second connecting portion 232 is lapped on the idler hanging rod 11, so that the weight of the weight tray 21 is borne by the idler hanging rod 11, realizing the loading of the weighing idler 1. Simplify the structure of the weighing idler loading device 1000. Optionally, in other embodiments, the first connecting portion 231 and the second connecting portion 232 may also be convex portions or barb structures protruding laterally along the connecting member 23, and the lap joint with the annular assembly 24 and the idler hanging rod 11 can be realized through the convex portions or barb structures. In this solution, by setting the first connecting portion 231 and the second connecting portion 232 as annular, the connection stability between the connecting member 23 and the annular assembly 24 can be improved, the safety of the weighing idler loading device 1000 can be guaranteed, and the potential safety hazard caused by the disengagement of the connecting member 23 and the annular assembly 24 can be avoided.

[0037] Optionally, to ensure the connection strength between the first connecting portion 231 and the second connecting portion 232, the first connecting portion 231 and the second connecting portion 232 are fixed by welding. In this embodiment, the bottom of the first connecting portion 231 is welded to the top of the second connecting portion 232 to ensure the connection stability between the two. In other embodiments, the first connecting portion 231 and the second connecting portion 232 may also be fixed by bolts or snap connections. For example, a plate-shaped connecting structure is provided at the junction of the first connecting portion 231 and the second connecting portion 232, and the connecting structure is penetrated by bolts and locked with nuts to realize the connection between the first connecting portion 231 and the second connecting portion 232. Or, by providing barbs and engaging structures on the first connecting portion 231 and the second connecting portion 232, the first connecting portion 231 and the second connecting portion 232 are hooked or snapped, which can be specifically selected according to actual needs.

[0038] In an alternative embodiment, to detect the position of the cross bar 31, the lifting mechanism 3 further includes a detection component. The detection component 33 is electrically connected to the driving member 32. The detection component 33 includes a first detection switch 331 and a second detection switch 332. The first detection switch 331 and the second detection switch 332 are arranged at intervals in the vertical direction. The first detection switch 331 is used to detect the first position of the cross bar 31, and the second detection switch 332 is used to detect the second position of the cross bar 31. Please refer to Figure 1, it is electrically connected to the driving member 32 through the first detection switch 331 and the second detection switch 332, so as to send a signal for reminder when the driving member 32 drives the cross bar 31 to move to the first position and the second position, control the driving member 32 to stop moving, and enable the weighing roller loading device 1000 to switch more accurately between loading and unloading.

[0039] To further improve the reliability of the detection switch 33, both the first detection switch 331 and the second detection switch 332 include two. The two first detection switches 331 are arranged side by side in the vertical direction, and the two second detection switches 332 are arranged side by side in the vertical direction. Please refer to Figure 1 , redundant detection is carried out by arranging two first detection switches 331 and two second detection switches 332 side by side. On the one hand, the reliability and accuracy of the detection data can be guaranteed by detecting simultaneously with the two detection switches 33. On the other hand, even if one detection switch 33 fails, the other detection switch 33 can continue to detect as a backup detection switch 33 to ensure the continuous and stable operation of the weighing roller loading device 1000.

[0040] In an optional embodiment, the hanging weight mechanism 2 includes two groups, and the two hanging weight mechanisms 2 are respectively arranged on both sides of the axis of the weighing roller 1. During the actual hanging weight calibration of the belt scale, hanging weights can be carried out on one side of the belt scale, or on both sides of the belt scale. When it is necessary to hang weights on both sides of the belt scale, hanging weight mechanisms 2 can be arranged on both sides of the weighing roller 1, and the driving member 32 is used to drive the cross bars 31 on both sides to move up and down to realize the loading and unloading process. Further, to realize the synchronous movement of the hanging weight mechanisms 2 on both sides, the weighing roller loading device 1000 further includes a synchronous rod 4. The synchronous rod 4 is arranged above the driving member 32, and both ends of the synchronous rod 4 in the axial direction are respectively connected to a cross bar 31. By using the synchronous rod 4, the movement states of the cross bars 31 on both sides of the weighing roller 1 are kept consistent, so as to ensure that the loading and unloading on both sides are carried out simultaneously and ensure the accuracy of the hanging weight calibration. In addition, the synchronous rod 4 can also be used as a transmission member for the hanging weight mechanisms 2 on both sides. For example, by connecting the output end of the driving member 32 to the synchronous rod 4, the synchronous movement of the cross bars 31 on both sides can be realized, and specific selection can be made according to actual needs.

[0041] In an optional embodiment, to realize the lifting movement of the cross bar 31, the driving member 32 is a lift. During the actual operation process, to realize the lift driving the cross bar 31 to move up and down, the main shaft of the lift can be driven to move linearly by a linear motor, or the movement of the main shaft of the lift can be realized by the way of turning a handwheel, and specific selection can be made according to actual needs.

[0042] The above are only exemplary embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included within the patent protection scope of the present utility model.
