Printing material interruption detection device for 3D printer and 3D printer

Abstract

The invention belongs to the technical field of 3D printers, and discloses a printing material interruption detection device for a 3D printer. The printing material interruption detection device comprises a detection pipe, wherein an infrared emitter and an infrared receiver are symmetrically installed on the two side walls of the detection pipe, a material guide pipe is installed inside the detection pipe, first through holes are symmetrically formed in the lower ends of the two side walls of the material guide pipe, first inserting grooves are symmetrically formed in the front end and the rear end of the inner wall of the detection pipe, and first inserting strips matched with the first inserting grooves are symmetrically fixed to the lower ends of the front wall and the rear wall of thematerial guide pipe. According to the printing material interruption detection device, by additionally arranging the first inserting grooves and the first inserting strips, when the material guide pipe is installed inside the detection pipe, the first inserting strips can be inserted into the first inserting grooves, the material guide pipe can be effectively limited and prevented from being dislocated, it is guaranteed that the first through hole right faces the infrared emitter and the infrared receiver, the accuracy of interruption detection is improved, and in addition, by additionally arranging a fastening assembly, the stability of the material guide pipe installed inside the detection pipe can be further improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a 3D printer printing material intermittent detection device and a 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. , 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacture of some products. There are already zero parts printed using this technology. 3D printer is a three-dimensional printer based on 3D printing technology. It is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital mo...
