Continuous feeding device of internal mixer

The continuous feeding device comprises an internal mixing chamber body, an electronic scale body and a feeding bin, the internal mixing chamber body is transversely arranged, and the top of the internal mixing chamber body is vertically and fixedly communicated with a feeding pipe. The electronic scale has the beneficial effects that the charging bin and the electronic scale body are detachably fixed at the top of the internal mixing chamber body in a manner that the matching seat is in vertical sliding fit with the matching groove and the limiting rod is in transverse sliding fit with the limiting hole, and a discharging pipe of the charging bin and a feeding pipe of the internal mixing chamber body are coaxially contrasted; in this way, metering can be conducted through the electronic scale body in the process of pouring rubber raw materials into the feeding bin, then the material amount meeting the feeding weight is obtained in the feeding bin, and the material amount meeting the feeding weight is conveni
