Detailed implementation mode

[0026] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, a material weighing machine, base 20, the base 20 is in the shape of a rectangular plate, the center of the top of the base 20 is fixedly connected with a weighing module 21, the four corners of the top of the base 20 are fixedly connected with limiting rods 22, and a limiting groove 26 is formed on the wall surface of each limiting rod 22. The weighing module 21 is a prior art (publication number: CN208420147U). This is the existing technology, so it will not be elaborated here.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a loading structure, the loading structure is arranged on the top of the base 20, and the loading structure can quickly unload the weighed materials. The loading structure includes: a moving plate 30, a frame 31 and a loading hopper 32. The moving plate 30 is movably connected to the top of the base 20, the frame 31 is symmetrically and fixedly connected to the top of the moving plate 30, and the loading hopper 32 is rotatably connected between the symmetric frames 31. The loading hopper 32 is an isosceles triangular box with an open top and a hollow cavity.

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the moving plate 30 is a rectangular plate. The four corners of the moving plate 30 can vertically slide up and down in the limiting grooves 26 on the wall surfaces of the corresponding limiting rods 22 respectively. The bottom of the moving plate 30 can contact the top of the weighing module 21. The loading hopper 32 can flip between the symmetrical frames 31. The two side wall surfaces of the loading hopper 32 are inclined planes. The loading structure further includes a rotating shaft 33, an auxiliary shaft 34 and an auxiliary groove 35. The rotating shaft 33 is symmetrically and fixedly connected to the front and rear wall surfaces of the loading hopper 32. The auxiliary shaft 34 is also symmetrically and fixedly connected to the front and rear wall surfaces of the loading hopper 32. The auxiliary groove 35 is opened on the wall surface of each frame 31 facing the loading hopper 32. The rotating shaft 33 is located at an eccentric position on the upward-facing wall surface of the loading hopper 32. The auxiliary shaft 34 is located vertically below the rotating shaft 33. Both the rotating shaft 33 and the auxiliary shaft 34 are cylindrical. The corresponding rotating shaft 33 on each wall surface can pass through the wall surface of the frame 31 and rotate on the wall surface of the frame 31. The auxiliary groove 35 is an arc-shaped groove. The corresponding auxiliary shaft 34 on each can slide along the auxiliary groove 35. An auxiliary structure is also provided above the base 20. The auxiliary structure includes an auxiliary block 36 and a vibrating rod 37. The auxiliary block 36 is symmetrically and fixedly connected to the two side wall surfaces of the loading hopper 32. The auxiliary block 36 is a rectangular block. The vibrating rod 37 is symmetrically and fixedly connected to the inclined plane in the cavity of the loading hopper 32. The vibrating rod 37 is a rod with an isosceles triangle cross-section. A plurality of vibrating rods 37 are evenly arranged on the inclined plane of the loading hopper 32;

[0030] During specific use, the materials to be weighed are poured into the top opening of the loading hopper 32. After the materials enter the cavity of the loading hopper 32, they will concentrate and accumulate at the middlemost position in the cavity of the loading hopper 32 along the inclined plane in the cavity of the loading hopper 32. At this time, the materials will press down the structure on the wall surface of the loading hopper 32. At this time, the position of the moving plate 30 will move downward between the brackets 23 and contact the top structure of the weighing module 21. At this time, the weighing module 21 can weigh the materials loaded in the cavity of the loading hopper 32. After obtaining the data and when it is necessary to unload the materials in the cavity of the loading hopper 32, a motor capable of driving the rotating shaft 33 to rotate is installed on the wall surface of the frame 31. When the power of this motor is turned on, the motor can drive the rotating shaft 33 to rotate, thereby driving the loading hopper 32 to flip with the rotating shaft 33 as the center. After the loading hopper 32 flips, the materials in the cavity of the loading hopper 32 will pour out downward along the inclined plane in the cavity of the loading hopper 32. When the materials pour out from the cavity of the loading hopper 32, they will contact the inclined plane of the vibrating rod 37. When the loading hopper 32 flips, it will drive the auxiliary shaft 34 to move along the auxiliary groove 35. After all the materials are poured out, the motor will drive the rotating shaft 33 to drive the loading hopper 32 to rotate back to its original position;

[0031] In summary, by setting the loading structure, accurate weight can be obtained and the weighed materials can be unloaded. The loading structure can automatically converge the materials towards the center of the top of the base 20 through the inclined plane in the cavity of the loading hopper 32, and the loading hopper 32 can directly pour out all the materials in its cavity by flipping. Therefore, this solution has the advantages of accurate weighing data and convenient unloading.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the auxiliary structure further includes a bracket 23, a servo motor 24 and a limiting plate 25. The bracket 23 is fixedly connected to the top of the symmetric limiting rods 22 at the rear position. The servo motor 24 is fixedly connected to the top of each bracket 23. The limiting plate 25 is rotatably connected to the wall surface of the bracket 23. The bracket 23 is in the shape of an inverted L-shaped plate. The limiting plate 25 is located between the bracket 23 and the top of the limiting rods 22. The servo motor 24 can drive the limiting plate 25 to rotate. The limiting plate 25 is in the shape of a capsule-like plate;

[0033] When in specific use, when the loading hopper 32 is fixed in the inverted state by the rotating shaft 33, the power supply of the servo motor 24 can be controlled to drive the limiting plate 25 to turn forward so that the inclined surface of the bracket 23 contacts the wall surface of the limiting plate 25. And when the material is unloaded from the cavity of the loading hopper 32, there will be a jerky feeling due to the shock rod 37, and the material fixed in the cavity of the loading hopper 32 will be shaken off;

[0034] In summary, by setting the auxiliary structure, the loading hopper 32 can be supported by the limiting plate 25 to prevent the loading hopper 32 from moving when the loading hopper 32 is turned and fixed. Through the shock rod 37, when unloading, the moving material can generate a jerky feeling in the cavity of the loading hopper 32, and the material fixed in the cavity of the loading hopper 32 can be shaken off by using the vibration brought by the jerky feeling, so that there is no need to manually rake the material piled up in the cavity of the loading hopper 32.

[0035] Working principle: Pour the material to be weighed from the top opening of the loading hopper 32. After the material enters the cavity of the loading hopper 32, it will concentrate and accumulate along the inclined surface in the cavity of the loading hopper 32 at the middlemost position in the cavity of the loading hopper 32. At this time, the material will press down the structure of the wall surface of the loading hopper 32. At this time, the position of the moving plate 30 will move downward between the brackets 23 and contact the top structure of the weighing module 21. At this time, the weighing module 21 can weigh the material loaded in the cavity of the loading hopper 32. After obtaining the data and when it is necessary to unload the material in the cavity of the loading hopper 32, a motor capable of driving the rotating shaft 33 to rotate is installed on the wall surface of the rack 31. Turn on the power supply of this motor, and the motor can drive the rotating shaft 33 to rotate, thereby driving the loading hopper 32 to turn around the rotating shaft 33. After the loading hopper 32 turns, the material in the cavity of the loading hopper 32 will pour downward along the inclined surface in the cavity of the loading hopper 32. When the material pours out of the cavity of the loading hopper 32, it will contact the inclined surface of the shock rod 37. When the loading hopper 32 turns, it will drive the auxiliary shaft 34 to move along the auxiliary groove 35. After all the material is poured out, the motor will drive the rotating shaft 33 to drive the loading hopper 32 to rotate back to the original position.
