Abstract

本发明公开了一种PVC塑料用3D打印喷头进料装置及3D打印喷头，涉及3D打印喷头技术领域，一种PVC塑料用3D打印喷头进料装置，包括送料管道，送料管道的外部贴合设置有限位块，限位块底端的外表面螺纹连接有散热管，散热管的内部贴合设置有喉管，喉管底端的外表面可拆卸固定安装有加热块，喉管底端的内表面螺纹连接有喷嘴，还包括设置于送料管道内部的清理组件；通过疏通杆、螺旋输送通道与支撑弹簧的设置，在3D打印完成后对喷嘴内部进行清理，进而避免喷嘴堵塞，疏通杆可顶开喷嘴内凝固的杂质，而螺旋输送通道的旋转运动能通过剪切力分解结晶体或碳化残留物，且螺旋结构在推送残渣时同步转动，可带走附着在通道内壁的微小颗粒，减少二次堆积风险。
