[0088] Bracket 110;

[0089] A double-ended hopper 120, the double-ended hopper 120 is arranged on the bracket 110;

[0090] A plurality of hopper assemblies 130, wherein the plurality of hopper assemblies 130 are arranged on the bracket 110, the plurality of hopper assemblies 130 are all located above the double-head hopper 120, and the plurality of hopper assemblies 130 have a feeding end;

[0091] A material discharge assembly 140, the material discharge assembly 140 is disposed on the bracket 110, and a discharge end of the material discharge assembly 140 corresponds to a feed end of a plurality of hopper assemblies 130;

[0092] The blanking assembly 150 is disposed on the double-headed hopper 120 , and the blanking assembly 150 is located at the discharge end of the double-headed hopper 120 .

[0093] In this embodiment,

[0094] During use, materials are added into the unloading assembly 140, and the materials are input into several hopper assemblies 130 through the unloading assembly 140. The uppermost layer of the hopper assembly 130 is fed by the principle of screw conveying, so that the viscous materials can be easily conveyed into the hopper assembly 130. The hopper assembly 130 is divided into three layers, and the materials can be weighed and pre-stored respectively through the three-layer hopper assembly 130. When the materials need to be taken, they can be directly conveyed through the hopper assembly 130, thereby reducing the time required for unloading and increasing the weighing speed of the materials. After processing, the materials in the hopper assembly 130 are conveyed into the double-headed hopper 120 according to the required quality, and then the materials are output from the double-headed hopper 120 by controlling the unloading assembly 150;

[0095] By setting the hopper assembly 130 into three layers, the three-layer hopper assembly 130 can be used to weigh and pre-store materials respectively. When the material needs to be taken, it can be directly transported through the hopper assembly 130, thereby increasing the time required for unloading and the weighing speed of the material. The material is input into several hopper assemblies 130 through the unloading assembly 140, and the uppermost layer of the hopper assembly 130 is fed by the principle of screw conveying, thereby facilitating the transportation of viscous materials into the hopper assembly 130.

[0096] like Figure 2 As shown, in one embodiment,

[0097] The hopper assembly 130 includes:

[0098] A feeding assembly 131, which is disposed on the bracket 110, and corresponds to a discharge end of the blanking assembly 140;

[0099] A first hopper assembly 132, which is disposed on the bracket 110, and is located below the feed assembly 131. The feed assembly 131 conveys the material into the first hopper assembly 132;

[0100] A second hopper assembly 133, the second hopper assembly 133 is disposed on the bracket 110, and the second hopper assembly 133 is located below the first hopper assembly 132;

[0101] A third hopper assembly 134, which is disposed on the bracket 110 and is located below the second hopper assembly 133;

[0102] The material dropping channel 135 is arranged on the bracket 110 , the material dropping channel 135 is arranged below the third hopper 1342 , and the material dropping channel 135 is located above the double-headed hopper 120 .

[0103] In this embodiment, after the material is added into the unloading component 140, the viscous material is conveyed into the first hopper component 132 through the spiral conveying of the feeding component 131, and the material is pre-stored through the first hopper component 132. When unloading is required, the first hopper component 132 is opened, and the material falls into the second hopper component 133 under the action of gravity, and is weighed according to the demand through the second hopper component 133. When the required amount of material is reached, the first hopper component 132 is closed. When the first hopper component 132 is closed, the second hopper component 133 is opened, and the weighed material falls into the third hopper component 134, and the weighed material is stored in the third hopper component 134. When needed, the third hopper component 134 is opened, and the weighed required material is conveyed to the corresponding hopper through the unloading channel 135.

[0104] By adding a second hopper assembly 133, materials can be pre-conveyed to the first hopper assembly 132. Before unloading, materials can be pre-conveyed to the second hopper assembly 133 through the first hopper assembly 132. After weighing according to the required mass, the second hopper 1331 conveys the materials to the third hopper assembly 134 for storage. When batching is required, the materials are directly conveyed to the double-headed hopper 120 through the feeding channel 135 through the third material assembly, thereby increasing the weighing speed and reducing the time for replenishing materials.

[0108] The second spiral feeding member 1312 is disposed on the bracket 110 , and the second spiral feeding member 1312 is located above the first spiral feeding member 1311 .

[0109] In this embodiment, the first spiral feed member 1311 is driven by a motor, and the motor is arranged on the bracket 110. The first spiral feed member 1311 is a rotating rod with a thread, and the viscous material is rotated and transported by the rotation of the rotating rod. The second spiral feed member 1312 is driven by a motor, and the motor is also arranged on the bracket 110. The second spiral feed member 1312 is also a rotating rod with a thread. The length of the second spiral feed member 1312 is smaller than that of the first spiral feed member 1311. The viscous material is transported from the unloading component 140 to the first spiral feed member 1311 through the second spiral feed member 1312. When there is too much material at the first spiral feed member 1311, the rotation direction of the second spiral feed member 1312 can also be set to be opposite to the rotation direction of the first spiral feed member 1311, thereby controlling the amount of material at the first spiral feed member 1311.

[0120] In this embodiment, two first connecting frames 1321 are provided, and the two first connecting frames 1321 are symmetrical about the first hopper 1322. One end of the first transmission member 1323 is rotatably provided on one of the connecting frames, and the first transmission member 1323 is located on one side of one of the first connecting frames 1321. A connecting rod 13281 is provided on the first transmission member 1323, and one end of the connecting rod 13281 extends to the other first connecting frame 1321, and a corresponding movable block is provided. When the first driving component 1328 is started, the first driving component 1328 makes the connecting rod 13281 move, thereby making the first transmission member 132 The first transmission member 1323 is rotated with the connection point of the first transmission member 1323 as the axis, so that the first transmission member 1323 is movable, and the first stopper 1325 is controlled to rotate with the connection point of the first hopper 1322 as the center. Under the action of the meshing of the teeth on the first stopper 1325 and the second stopper 1326, the first stopper 1325 and the second stopper 1326 move simultaneously, so that the first hopper 1322 is opened. Through the setting of the first spring 1327, when the first driving component 1328 is not in contact with the connecting rod 13281, the first spring 1327 pulls the first transmission member 1323, so that the first stopper 1325 and the second stopper 1326 are reset.

[0121] Furthermore, two first transmission members 1323 may be provided to facilitate the normal movement of the connecting rod 13281 when the first driving assembly 1328 applies pressure to the connecting rod 13281;

When the motor rotates, the rotating rod 13282 is driven to rotate, thereby rotating the adjusting roller 13283. When the adjusting roller 13283 rotates, it contacts the connecting rod 13281 for a period of time, and then the connecting rod 13281 is pressed down by the adjusting roller 13283, thereby driving the rotation of the first transmission member 1323.
