The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0035] Specifically, the weight of the material on the belt is measured by the middle measuring assembly 210 and the bias measuring assemblies 220 on the two sides, and then it is judged which side of the material on the conveying belt is heavier (i.e., which side is heavier) according to the weight deviation on the two sides of the bias measuring assembly 220, and the bias weight information is generated.

[0036] The weighing mechanism 300 is used to obtain the weight of the material, and the weighing mechanism 300 comprises a mobile weighing assembly 310 and a side weighing assembly 320, wherein the mobile weighing assembly 310 is movably arranged on the mounting frame 100; the side weighing assembly 320 is arranged in two groups, and the two groups of side weighing assemblies 320 are arranged at preset angles on the mounting frame 100; and the two groups of side weighing assemblies 320 are respectively located on the two sides of the mobile weighing assembly 310.

[0037] Specifically, the mobile weighing assembly 310 adjusts the position of the mobile weighing assembly 310 according to the bias weight information obtained by the bias weight measuring mechanism 200, so that the mobile weighing assembly 310 moves to the side with more weight, so that the center of gravity of the material passes directly above the mobile weighing assembly 310, so as to reduce the weighing error caused by the bias weight of the material on the conveying belt.

[0038] The speed measuring mechanism 400 is used to measure the running speed of the conveying belt on the conveying device; the display mechanism 500 is used to display the obtained weight value; the server 600 is connected with the bias weight measuring mechanism 200, the weighing mechanism 300, the speed measuring mechanism 400 and the display mechanism 500, and the server 600 is used to obtain the bias weight information through the bias weight measuring mechanism 200, and convert it into a mobile signal to control the mobile weighing assembly 310 to move, and obtain the running speed of the conveying belt through the speed measuring mechanism 400, and display the obtained information through the display mechanism 500.

[0040] Therefore, the material conveying high-precision weighing device of the embodiment of the present application can reduce the weighing error caused by the weight deviation of the material on the conveying belt by measuring the weight deviation information of the material and timely adjusting the stress center of the weighing mechanism 300, thereby facilitating to improve the weighing precision during the material conveying.

[0042] Specifically, the middle measurement assembly 210 and the bias measurement assemblies 220 on the two sides respectively include the middle measurement gravity sensor 213 and the bias measurement gravity sensor 223 for weighing, so that the middle measurement assembly 210 and the bias measurement assemblies 220 on the two sides can cooperate to measure the total weight of the material on the belt. In addition, according to the weight deviation values on the bias measurement gravity sensors 223 on the two sides, it can be judged which side of the material on the conveying belt is heavier (i.e., which side bears more weight), and the weight deviation information can be generated.

[0043] To clearly illustrate the above embodiment, in an embodiment of the present application, as shown in Figure 3 and Figure 4 , the mobile weighing assembly 310 includes a mobile weighing roller 311, a mobile weighing bracket 312, a mobile weighing sensor 313, a mobile bracket 314, a driving motor 315, a driving screw 316, and a screw fixing piece 317, wherein the mobile weighing roller 311 is arranged on the mobile weighing bracket 312, and the mobile weighing sensor 313 is arranged below the mobile weighing bracket 312; the driving motor 315 is arranged on one side of the mounting rack 100, the output end of the driving motor 315 is connected with the driving screw 316, the driving screw 316 extends to the two sides of the mounting rack 100, the movement of the driving screw 316 is connected with the driving motor 315, the other end of the driving screw 316 is connected with the screw fixing piece 317, and the screw fixing piece 317 is installed on the other side of the mounting rack 100; the mobile bracket 314 is arranged on the driving screw 316, and the mobile weighing sensor 313 is arranged above the mobile bracket 314.

[0044] Specifically, the driving motor 315 drives the driving screw 316 to rotate, and the driving screw 316 can drive the moving bracket 314 and the components installed on the moving bracket 314 to move along the length direction of the driving screw 316.

[0045] As a possible case, as shown in Figure 2 The moving weighing sensor 313 is provided with two, which are respectively connected with the two ends of the moving weighing bracket 312.

[0046] Specifically, when the unstable bulk material is weighed, even if the center of gravity of the material changes, as long as the center of gravity is between the two moving weighing sensors 313, high-precision weighing effect can be achieved.

[0047] As another possible case, as shown in Figure 4 The moving weighing assembly 310 further includes a slide rod, which is arranged in parallel with the driving screw 316, the slide rod is inserted into the moving bracket 314, and the two ends of the slide rod are respectively connected with the two sides of the mounting frame 100.

[0048] Specifically, the slide rod is inserted into the moving bracket 314 together with the driving screw 316, which can limit the rotation of the moving bracket 314 and improve the stability during use of the embodiment.

[0049] In addition, as shown in Figure 5 The moving weighing roller 311 is provided with a plurality of rotatable balls.

[0050] Specifically, the balls on the moving weighing roller 311 can change the sliding friction between the moving weighing roller 311 and the conveying belt into rolling friction, reducing the friction between the moving weighing roller 311 and the conveying belt. This can not only reduce the friction loss of the conveying belt, but also reduce the working load of the driving motor 315, which is beneficial to improve the service life of the embodiment.

[0052] Specifically, the side weighing assembly 320 and the mobile weighing assembly 310 jointly weigh the material on the conveying belt, and according to the vertical component force of the conveying belt on the mobile weighing assembly 310 and the side weighing assembly 320 and the conveying speed of the conveying belt, the weight of the material conveyed by the conveying belt in a certain distance is obtained.

[0053] For the sake of clarity of the above embodiment, in an embodiment of the present application, the server 600 is installed on the mounting frame 100, and the speed measuring mechanism 400 is installed on the conveying device and is in contact with the return conveying belt on the conveying device. Specifically, the contact between the speed measuring mechanism 400 and the return conveying belt is convenient for installation of the embodiment of the present application, and the measured conveying speed of the conveying belt is more accurate.

[0055] The server 600 obtains the eccentric weight information, and according to the eccentric weight information, the server 600 controls the driving motor 315 to work, the driving motor 315 drives the driving screw 316 to rotate, and the driving screw 316 can drive the mobile bracket 314 and the components installed on the mobile bracket 314 to move along the length direction of the driving screw 316. The mobile weighing assembly 310 is moved to the side bearing more weight, so that the center of gravity of the material passes above the mobile weighing assembly 310.

[0056] According to the weight information measured by the adjusted weighing mechanism 300 and the conveying speed information of the conveying belt measured by the speed measuring mechanism 400, the server 600 can obtain the weight value of the material conveyed by the conveying belt in a certain distance.

[0057] For example, in combination with Figure 2 As shown in the figure, if the width of the conveying belt is 10, and the weight bearing ratio of the left side eccentric weighing measuring assembly to the right side eccentric weighing measuring assembly is 1:1.5, the mobile weighing assembly 310 is controlled to move to the right side by 0.5.

[0058] In summary, the material conveying high-precision weighing device of the embodiment of the present application measures the eccentric weight information of the material, and adjusts the force center of the weighing mechanism 300 in time according to the eccentric weight information, so as to reduce the weighing error caused by the eccentric weight of the material on the conveying belt, which is beneficial to improve the weighing precision during the material conveying.
