Abstract

The invention discloses an intelligent glue spreading device for fused deposition modeling 3D printing. The intelligent glue spreading device has the main function of controlling the glue output speed; meanwhile, the glue output is stopped when the glue spreading device is shut down, and the glue is spread when the glue spreading device is turned on; the glue output is controlled accurately, and the key point lies in the accuracy of the glue spreading device; through control of the rotation speed of a screw extrusion rod by a transmission, the glue output speed can be controlled strictly; under the condition that the thread edge of the lower end of the screw extrusion rod is precisely attached to the inner pipe wall of a nozzle, the glue hardly flows out during shutdown of the glue spreading device, and the glue output can be accurately controlled by the control of the rotation speed of the screw extrusion rod according to articles to be printed and the type of glue stock when the gluespreading device is turned on.

Description

technical field [0001] The invention relates to the technical field of 3D printing forging molds, in particular to a fuse deposition 3D printing intelligent gluing device. Background technique [0002] Fused deposition modeling uses a hot-melt spray head to make semi-fluid materials extrude and deposit at designated positions to solidify and form according to the path controlled by CAD layered data. After layer-by-layer deposition and solidification, the entire prototype or part is formed. This technology is also known as For melt stacking, melt extrusion molding, etc. [0003] One spray head is used to deposit model material and one spray head is used to deposit support material. Generally speaking, the material wire of the model material is fine and the cost is high, and the deposition efficiency is low, while the support material wire is thick and the cost is low, and the deposition efficiency is also high. In addition to high deposition efficiency and reduced model pro...
