Title
(EN) Sprinkler for high precision automatic leveling and 3D printer
(ZH) 一种高精度自动调平用喷头和3D打印机
Abstract
(EN) The invention discloses a sprinkler for high precision automatic leveling and a 3D printer, and belongs to the field of 3D printing. The sprinkler for high precision automatic leveling comprises heatsinks, a throat pipe, limiting tables and position sensors, wherein the heat sinks are used for installing on the 3D printer, loading plates are connected to the heat sinks, heating blocks are furtherarranged on the loading plate, and the heat sinks and the heating blocks are arranged on the same sides of the loading plates; one end of the throat pipe is arranged in the heat sinks in a penetrating mode, the other end of the throat pipe is arranged in the heating blocks in a penetrating mode, the throat pipe is arranged in the heat sinks and the heating blocks in the axis direction of the throat pipe in a slidably moving mode, the throat pipe is connected to the inner walls of the heating blocks in an abutting mode, and a nozzle is further arranged at one end, near the heating blocks, of the throat pipe; the limiting tables for the throat pipe or the nozzle to abutting connect are arranged on the heating blocks, and the limiting tables are arranged on one side, near the nozzle, of thethroat pipe; the position sensors are arranged on the heat sinks, a trigger piece is arranged on the throat pipe for connecting to the position sensors in an abutting mode, and the position sensors are arranged on the side, away from the nozzle, of the trigger piece. The possibility of deformation of a printing platform is reduced, and the leveling accuracy of the printing platform is increased.
(ZH) 本发明公开了一种高精度自动调平用喷头和3D打印机,涉及3D打印领域。包括:用于安装在3D打印机上的散热片,散热片上连接有载板,载板上还设有加热块,散热片与加热块设置于载板的同一侧;喉管,喉管的一端穿设在散热片内,喉管的另一端穿设在加热块内,喉管沿其轴线方向滑移设置在散热片内及加热块内,喉管抵接于加热块的内壁上,喉管靠近加热块的一端还设有喷嘴;加热块上设有用于喉管或喷嘴抵接的限位台,限位台设置于喉管靠近喷嘴的一侧;散热片上设有位置传感器,喉管上设有用于抵接于位置传感器的触发片,位置传感器设置于触发片远离喷嘴的一侧。减小了打印平台形变的可能,增加了打印平台的调平精度。
