Fluid material conveying device for 3D printing machine

Abstract

The invention discloses a fluid material conveying device for 3D printing machine. The fluid material conveying device comprises a discharging pipe, a connection pipe, a feeding pipe, a pneumatic pipe, a mounting plate and a bottom plate. The discharging pipe, the connection pipe and the feeding pipe are all mounted on the mounting plate through fixing parts, the mounting plate is arranged on the bottom plate, a discharging tank and a feeding tank are arranged on two sides of the bottom plate respectively, and a liquid level sensor is arranged on one side of the discharging tank. The fluid material conveying device for the 3D printing machine has advantages that by constant changing of electromagnet poles, a cylindrical magnet drives a piston to continuously move up and down so as to change internal air pressure of the pneumatic pipe, then fluid materials in the feeding tank are conveyed into the discharging tank, a user can precisely control feeding speed only by changing exchange frequency of the electromagnet poles, liquid level change of the fluid materials in the discharging tank can be sensed by the liquid level sensor on the side wall of the discharging tank, and accordingly precision in feeding quantity control is realized.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a fluid material delivery device for a 3D printer. Background technique [0002] Existing 3D printers mostly use syringe type or air pressure jet type when printing materials are fluid materials (such as pastry batter for printing, ceramic slurry, etc.). The syringe type cannot achieve continuous feeding, and at the same time cannot accurately control the extrusion volume and extrusion speed of the feed. When the syringe type is used up, the syringe needs to be replaced, which is time-consuming and difficult. Pneumatic injection requires an air pump, which is costly and bulky, and is not suitable for desktop machines. None of the existing solutions can accurately control the extrusion volume and extrusion speed. Contents of the invention [0003] The purpose of the present invention is to provide a 3D printer fluid material conveying device to solve the problems r...
