A nozzle rotating dual-nozzle cement 3D printing structure and its application method

Abstract

The invention relates to a nozzle rotating dual-nozzle type cement 3D printing structure and its use method. It includes a column, and the nozzle assembly is installed symmetrically on its side; the single-group nozzle assembly includes a support seat fixed to the column, and a feeding cylinder is fixed on the outside of the support seat. , the feeding motor is installed above the feeding cylinder, and the output end of the feeding motor facing downward is installed with a screw shaft, and the screw shaft extends downward into the feeding cylinder; the connecting extrusion cylinder is installed at the bottom of the feeding cylinder, and the bottom of the extrusion cylinder rotates through the nozzle Install the spout piece; the upper part of the side wall of the feed cylinder is provided with a feed inlet, which is connected to the external cement delivery pump through a hose; an automatic cutting and sealing mechanism is installed on the outer wall of the spout piece; cement enters through the hose under the action of the cement delivery pump In the feeding cylinder, the screw shaft rotates to extrude the cement downward, and the nozzle rotating component drives the nozzle to rotate relative to the extrusion cylinder; the two groups of nozzle components cooperate with each other or work independently, suitable for printing components of various shapes or colors, and have good practicability , High flexibility in use.

Description

technical field [0001] The invention relates to the technical field of cement 3D printing equipment, in particular to a cement 3D printing structure with rotating nozzles and double nozzles and a method for using the same. Background technique [0002] 3D printing is a rapid prototyping technology that uses some adhesive materials to construct models by printing them layer by layer. Mold manufacturing and industrial design industries are used to build models, and are gradually developing into product manufacturing, forming "direct digital manufacturing", so 3D printing is also called rapid prototyping, additive manufacturing, and laminated manufacturing. [0003] The 3D printing technology with the highest processing precision is light-curing printing technology. The printing material is usually photosensitive resin. The resin undergoes a curing reaction under a certain wavelength of laser light. To a line, and then extended from a line to a surface, so as to complete the p...

Problems solved by technology

[0004] In the existing technology, there are few equipments that can be really applied to 3D printing buildings, and they are very expensive. It is an urgent demand in the market to develop equipment matching new 3D printing building materials; the automation degree of existing 3D printing equipment is relatively low, and most of them are With manual control construction, it is necessary to set the splint of the construction model in advance, and then manually control the 3D printing equipment to pour cement; this method requires operators to have certain construction experience, and improper operation may lead to uneven cement pouring and affect the construction quality
