[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 — Figure 5 ,in, Figure 1 A schematic diagram of the overall structure of the automatic material addition and subtraction reweighing machine provided by this utility model; Figure 2 A vertical cross-sectional view of the second funnel of the automatic material weighing machine provided by this utility model; Figure 3 A horizontal cross-sectional view of the second funnel of the automatic material addition and subtraction reweighing machine provided by this utility model; Figure 4 A partial structural schematic diagram of the automatic material addition and subtraction reweighing machine provided by this utility model; Figure 5 This is a partial top view of the automatic material addition and subtraction reweighing machine provided by this utility model.

[0023] In practical implementation, the automatic material addition and subtraction reweighing machine has the following structure: Figure 1 — Figure 5 As shown, it includes: a mounting frame 1, a first funnel 2 detachably connected to the top of the mounting frame 1, a second funnel 3 connected to the bottom of the first funnel 2 via a conduit, a pressure pump 4 threadedly connected to the other end of the conduit, a conveying assembly 5 at the bottom of the mounting frame 1, a storage bag 6 placed above the conveying assembly 5, the second funnel 3 inserted into the storage bag 6, a sealing assembly 7 detachably connected to the side wall of the mounting frame 1 to seal the storage bag 6, and a display assembly 8 for monitoring the weight of the conveying assembly 5 installed on one side of the mounting frame 1;

[0024] It should be noted that the sealing assembly 7 includes a limiting frame 701, with a heat-melting end installed on the inner wall of the limiting frame 701. Multiple electric cylinders 702 are installed on one side of the heat-melting end. An abutment block 703 is installed on the inner wall of the limiting frame 701 opposite to the heat-melting end. The heat-melting end is located below the second funnel 3. When the display component 8 indicates that the weight of the material in the storage bag 6 has reached a preset value, the multiple electric cylinders 702 will automatically activate, pushing the heat-melting end to heat-seal the storage bag 6. If the material exceeds the preset value, the suction pump 4 will be activated to partially extract the material from the storage bag 6, reducing it to less than or equal to the preset value, before refilling or sealing.

[0025] The second funnel 3 includes a shell 31, a shielding component 32 is movably connected to the inner cavity of the shell 31 near the top, a support component 33 for supporting the storage bag 6 is movably connected to the inner cavity of the shell 31 near the bottom, and a drive component 34 for opening the drive support component 33 is detachably connected to the outer wall of the shell 31.

[0026] It should be noted that the material enters the second funnel 3 from the bottom of the first funnel 2 through the conduit. At this time, the shielding component 32 will rotate into the second funnel 3 under the pressure of the material, thus forming an angle with the horizontal plane, which can shield the dust raised by the material. By activating the drive component 34, the drive component 34 will drive the support component 33 to rotate, so that the support component 33 will fully open and limit the opening of the storage bag 6, thereby preventing the material from leaking out. The display component 8 monitors the weight of the material in the storage bag 6 in real time. When the material meets the quality requirements, it is transported away by the transmission component.

[0027] The shielding assembly 32 includes a plurality of sealing plates 321 arranged opposite to each other. The plurality of sealing plates 321 are movably connected to the inner cavity side wall of the mounting frame 1. An elastic element 322 is inserted inside the sealing plate 321. One end of the elastic element 322 is fixedly connected to the sealing plate 321, and the other end of the elastic element 322 is fixedly connected to the inner side wall of the outer shell.

[0028] The support assembly 33 includes a plurality of oppositely arranged arched plates 331, each of which is fixedly connected to a connector 332 at its bottom end. Each connector 332 is rotatably connected to the inner wall of the housing 31 and fits against the inner wall of the housing.

[0029] The drive assembly 34 includes multiple drive motors 341, all of which are bolted to the outer wall of the housing. Each drive motor 341 has a connecting rod 342 welded to its output end. The multiple connecting rods 342 pass through the corresponding arched plate 331 along the long side wall of the arched plate 331.

[0030] It should be noted that, since one end of the arched plate 331 is bent inward into a hook shape, the two arched plates 331 are rotated in different directions by the drive motor 341 to flip the arched plate 331 out of the housing 31, and the storage bag 6 is hooked by the hook of the arched plate 331. Thus, while the storage bag 6 is being opened, it can also be hung on the hook of the arched plate 331 to prevent the storage bag 6 from being compressed and falling off during the filling process.

[0031] The radius of the arched plate 331 is equal to half the width of the opening at the bottom of the housing 31, and the end of the arched plate 331 away from the connector 332 is bent inward in a hook shape.

[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
