and one end of the connecting rod 5c3 is fixedly connected with the output end of the right-angle reducer 5c2, and the other end of the connecting rod 5c3 is rotationally connected with the weighing hopper 3a1.
Specifically, when the materials in the weighing hopper 3a1 are fed, the second servo motor 5c1 is started, and under the action of the right-angle speed reducer 5c2 and the connecting rod 5c3, the weighing hopper 3a1 starts to rotate around the mounting frame 3a2 until the materials in the weighing hopper 3a1 fall onto the feeding chute 5b 2.
The working principle of the invention is as follows:
step one, a worker starts an automatic weighing device, and materials fall into a material placing component 3a of the weighing device 3 from a discharge port of the feeding device 2.
Step two, when the material falls into the material setting subassembly 3a from the discharge port of loading attachment 2, the material produces impact force to the material setting subassembly 3a of below to the weighing effect of the electronic scale 3b of fixing in material setting subassembly 3a below is influenced, therefore the elastic component 3c that sets up in electronic scale 3b below can absorb the impact force that produces when the material falls, improves the accuracy that the material was weighed to the maximum extent.
And thirdly, when the numerical value on the electronic scale 3b reaches a preset numerical value, the electric controller starts to control the lifting device 4a to start, and the lifting device 4a drives the weighing device 3 fixed above to descend until the weighing device reaches the working range of the blanking device 5.
In order to maintain the stability of the weighing device 3 during the descending process, a plurality of supporting components 4b are installed below the working end of the lifting device 4a, and the supporting components 4b uniformly distributed at the bottom of the lifting device 4a maintain the stability of the working end of the lifting device 4 a.
And step five, simultaneously, the working end of the lifting device 4a can provide power for the closing component 4c when the working end of the lifting device 4a descends, and the closing component 4c can pull the discharge hole blocking object of the feeding device 2 until the discharge hole is completely closed.
Step six, after the materials are weighed, the working end of the blanking device 5 can turn the materials in the material placing component 3a into the feeding and blanking device 5, and the weighed materials are conveyed into the next working procedure by the blanking device 5. After the weighing process is finished, the lifting device 4a can drive the weighing device 3 to reset, and meanwhile, the closing component 4c fixedly connected with the working end of the lifting device 4a can reversely pull the blocking object arranged at the discharge port of the feeding device 2 until the discharge port of the feeding device 2 is completely opened.
