The utility model relates to a mixing and feeding error prevention improvement facility, comprising: a matching bucket, comprising a bucket lid and a body having a matching space； a plurality of mixing liquid buckets for storing the compounding liquid, connecting the matching space by a plurality of pipelines, and setting the pipeline There is a valve to open or close the pipeline； a control module outputs a feeding command to control the valve to open or close the pipeline, so that the formulated liquid in the mixing tank is delivered to the mixing space； and a locking device is disposed on the body. After the mixing liquid tank delivers the mixing liquid to the mixing space according to the feeding instruction, the control module issues a locking command, the valve closes the pipeline according to the locking instruction, and the locking device locks the mixing space according to the locking instruction to seal the mixing space. This creation can avoid the problem of mismatching or incorrect feeding due to instability or negligence of personnel.一種調配投料錯誤防呆改善設施，包含：一調配桶，包含桶蓋及具有調配空間的本體；複數個用以存放調配液的調配液桶，藉由複數個管線連接調配空間，且管線上設有閥門，以開啟或關閉管線；一控制模組，輸出投料指令，以控制閥門開啟或關閉管線，使得調配液桶中的調配液輸送至調配空間中；以及一鎖定裝置，設置於本體上。於調配液桶依據投料指令輸送調配液至調配空間後，控制模組發出一鎖定指令，閥門依據鎖定指令關閉管線，且鎖定裝置依據鎖定指令鎖定桶蓋而密封調配空間。本創作可以避免因人員不穩定或疏忽導致調配異常或投料錯誤的問題。
