Near-end feeding three-inlet one-outlet color mixing spray head of 3D printer

Abstract

The invention discloses a near-end feeding three-inlet one-outlet color mixing spray head of a 3D printer. The spray head comprises small gears, cooling fans, cooling fins, big gears, a fixed platform, a stepping motor, throat pipes, a three-color mixing nozzle, a sliding rail, clamping bearings, a fixed joint and a gasket. The near-end feeding three-inlet one-outlet color mixing spray head has the beneficial effects that each small gear and the corresponding big gear are closely engaged to form a group, and the small gears and the big gears are divided into three groups; a fixator belongs toa metal handle made of a metal material; a threaded column is welded to the bottom end of the handle; a threaded through hole which is completely through is formed in a rotary rod; the cooling fins are fixed to the outer sides of the clamping bearings in a welding mode, and the upper and lower sides of the cooling fins are welded to the fixed platform; the three throat pipes are made of a corrosion-resistant plastic material and constitute feed inlets connected with threaded holes of the three-color mixing nozzle; the upper portion of the sliding rail is connected with a sliding block; the sliding rail of the sliding block is welded to the lower surface of the fixed platform, and the gasket is bonded to a connecting base of the fixed joint through corrosion-resistant glue.

Description

technical field [0001] The invention relates to a 3D printer near-end feeding three-input-one-out mixed-color nozzle, in particular to a 3D printer near-end feeding three-input-one-out mixed-color nozzle, belonging to the technical field of mechanical structures. Background technique [0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even In the spacecraft, the astronauts can print the shape of any required items, but the 3D printing is the model of the object, and the function of the object cannot be printed. On February 3, 2016, the 3D printing project of Fujian Institute of Material Structure, Chinese Academy of Sciences The Lin Wenxiong research group of the technology research and development center broke through the key technology of rapid prototyping of three-dimensional objects that can be printed continuously for the first time in China, and developed ...

[0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even In the spacecraft, the astronauts can print the shape of any required items, but the 3D printing is the model of the object, and the function of the object cannot be printed. On February 3, 2016, the 3D printing project of Fujian Institute of Material Structure, Chinese Academy of Sciences The Lin Wenxiong research group of the technology research and development center broke through the key technology of rapid prototyping of three-dimensional objects that can be printed continuously for the first time in China, and developed a super fast continuous printing digital projection (DLP) 3D printer. The recorded 600mm / s can "pull" a three-dimensional object with a height of 60mm from the resin tank in just 6 minutes, while the same object takes about 10 Hours, the speed has increased by a full 100 times! 3D printing industrializes space

[0003] The existing installation structure is relatively simple, and there are many hidden dangers. First, there is no heat dissipation treatment. When the temperature is too high, the internal parts will be melted by high temperature, resulting in damage to the instrument. Second, the materials cannot be fed synchronously, resulting in The uneven mixing prevents the unevenness of the produced objects from causing damage to the objects. Third, the conveying process is long, and the storage bin is set far away from the nozzle, which is easy to block when the material is conveyed
