[0020] The micro centralized supply and batching system in this embodiment adopts a top-down structure to fix the functional components in the tripod mechanism 1. The entire structure occupies a small area, has a simple structure, and saves costs. According to the formula requirements, the weighing device weighs different materials through the feeder 2 and puts them into the collecting hopper 4 to form the formula. In this process, since each feeder 2 is connected to a first chute 3, the feeders 2 will not affect each other when the PLC module outputs the instruction. The distributor rotates to mix the formula and puts the formula into the corresponding feeding monomer 601 through the second chute 501. Each formula corresponds to a corresponding feeding monomer 601. In this way, multiple formulas will not contaminate each other, and multiple formulas can be supplied in a short time, which speeds up the production efficiency.

[0021] Specifically, a first working platform 101 is provided on the top of the tripod mechanism 1, and a plurality of the feeders 2 are distributed in a circular array on the first working platform 101. Each of the feeders 2 is provided with a different material, and the feeder 2 includes a storage hopper 201 and a weighing hopper 202 connected up and down, and the output ends of the storage hopper 201 and the weighing hopper 202 are provided with a discharge door 203, and the weighing hopper 202 is connected to a weighing sensor 204, and the discharge door 203 and the weighing sensor 204 are both connected to the PLC module. Multiple feeders contain different materials, and each feeder 2 is independently operated. All actions are output by the PLC module, and the weighing signal enters the weighing module through the weighing sensor 204, so that the ingredients can be accurately mixed, and the storage hopper 201 is filled with materials according to the formula and actual needs.

[0022] Specifically, the top of the collecting hopper 4 is provided with a plurality of through holes matching the number and position of the first chute 3, the input end of the first chute 3 is connected to the feeder 2, and the output end of the first chute 3 passes through the through holes and extends into the collecting hopper 4. Preferably, the collecting hopper 4 is bucket-shaped, which is more conducive to the lowering of materials, and the bottom of the collecting hopper 4 is provided with an opening and closing port controlled by a solenoid valve. The tripod mechanism 1 is also provided with a second working platform 102, which is used to detect the collecting hopper 4 and the first chute 3, and the second working platform 102 and the first working platform 101 are connected by a ladder.

[0023] A central rotating shaft 503 is arranged in the center of the distributor 5, and a feed port 502 is arranged on the top of the central rotating shaft 503. The input end of the feed port 502 is connected to the output end of the collecting hopper 4, and the output end of the feed port 502 is connected to the input end of the second chute 501, and the second chute 501 is fixed on the central rotating shaft 503. As a preferred embodiment, a hose can be selected to connect the collecting hopper 4 and the distributor 5. A reducer and an absolute value encoder 506 are connected to the lower part of the central rotating shaft 503 through a reducer output shaft 504. The axis centerline of the reducer output shaft 504 and the centerline of the absolute value encoder 506 coincide with the axis centerline of the central rotating shaft 503, and the absolute value encoder 506 is connected to the PLC module.

[0024] The plurality of feeding monomers 601 are distributed in a circular array, and each feeding monomer 601 is provided with an inlet and an outlet 603. The position of the inlet matches the output end of the second chute 501 and is arranged at the top of the feeding monomer 601, and the position of the outlet 603 is arranged at the bottom of the feeding monomer 601. The distributor 5 in this embodiment has a separate bracket and is not connected to the feeding hopper 6. The central rotating shaft 503 of the distributor 5 rotates on the horizontal plane, and the second chute 501 rotates to the top of a specific feeding monomer 601 following the central rotating shaft 503. Preferably, the output end of the second chute 501 is provided with a solenoid valve to control the opening and closing of the output end. The material formula in the second chute 501 enters the feeding monomer 601, and each formula corresponds to a feeding monomer 601, and multiple formulas can be configured in a short time. The positioning limit uses an absolute encoder 506 for position verification, which is used to detect the rotation angle, and the resolution is 256.

[0025] Preferably, in the present embodiment, the feed hopper 6 provides two types, one is 8 feed monomers 601 distributed in a circular array, and the other is 22 feed monomers 601 distributed in a circular array. It should be understood that a specific number of feed monomers 601 can also be set according to production to meet the needs of configuring multiple recipes in a short period of time.

[0026] Preferably, an observation port 602 is provided on the side wall of each feeding unit 601 away from the center of the feeding hopper 6, so as to facilitate observation of whether the unloading is completed and whether there is any residue, so as to judge the fault.

[0028] Working method: the feeder 2 of the required material accurately weighs the required material according to the mixing ratio, and each feeder 2 discharges the material into the corresponding first chute 3 respectively. The required material enters the collecting hopper 4 and is mixed and then lowered to the distributor 5. The second chute 501 in the distributor 5 receives the signal and rotates to the top of the specific feeding monomer 601, and the material is lowered into the feeding monomer 601. Finally, the formula is obtained through the discharge port 603 at the bottom of the feeding monomer 601.

For those skilled in the art, without departing from the principle and spirit of the utility model, various changes, modifications, substitutions and variations are made to these implementations, which still fall within the scope of protection of the utility model.
