Quantitative conveying device of 3D printer

The utility model discloses a quantitative material conveying device of a 3D printer, which comprises a nozzle assembly, the nozzle assembly comprises a spray head, and the spray head comprises a flow channel; the device further comprises plugging plates which are symmetrically arranged, the plugging plates and the runner are located in the runner, the first end of each plugging plate is fixedly connected with a rotating part arranged in the spray head, and the second end of each plugging plate horizontally slides in a guide rail groove formed in the spray head. According to the quantitative material conveying device of the 3D printer, the purpose of dynamic quantitative material conveying is achieved, and therefore the situation that due to the fact that a nozzle is too high, material stacking occurs, and consequently local material stacking occurs to a printed model is avoided. 本实用新型公开了一种3D打印机定量输料装置，包括喷嘴组件，所述喷嘴组件包括喷头，所述喷头包括流道；还包括对称布置的封堵板件，且二者均位于所述流道内，其第一端与所述喷头内设置的旋转部固定连接，第二端水平滑动与所述喷头内开设的导轨槽内。该实用新型提供的3D打印机定量
