Intelligent feeding detection mechanism of 3D printer

Abstract

The invention discloses an intelligent feeding detection mechanism of a 3D printer. The intelligent feeding detection mechanism comprises a channel as well as a feeding sensor, a feeding speed sensor and a control system, wherein a printing material passes through the channel; signal receiving ends of the feeding sensor and the feeding speed senor are both connected with the channel; the feeding sensor is used for acquiring whether the printing material passes through the channel; the feeding speed sensor is used for acquiring the feeding speed of the printing material inside the channel; the control system is used for controlling the printer to stop working and to make an alarm when the feeding sensor senses that no material is fed into the channel or the material is not sufficient and the information is transmitted to the control system, and used for controlling the printer to stop working when the feeding speed sensor senses that the feeding speed of the printing material is zero and the information is transmitted to the control system. Through the adoption of the intelligent feeding detection mechanism, whether the material is blocked or insufficient in the printing process or not can be tested, and material replacement can be promoted, so that the printing success rate is ensured.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an intelligent feeding detection mechanism of a 3D printer. Background technique [0002] 3D printer is a kind of machine applied to rapid prototyping technology. 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. [0003] In recent years, 3D printing equipment based on 3DP, SLA, SLS and other technologies has been continuously updated, and new devices such as new nozzles and mechanisms have also been introduced. The continuous emergence of new devices and new materials has promoted the rapid development of 3D printing technology, especially FDM technology has been paid more attention due to its own advantages. FDM3D printing technology is widely used in many industries, and it also has certain requirements for the feeding mechanism. In order to realize au...

AI Technical Summary

Problems solved by technology

However, the existing technology has the following defects: 1. Material blockage occurs during the printing process, the machine continues to complete the printing by default, and it is impossible to judge whether the printing is normal, resulting in printing failure

2. When the material is used up during the printing process, the printer will continue to print by default until the printing process is completed, and it is impossible to judge whether there is material, resulting in printing failure

3. During the printing process of the printer, when the motor wire is damaged, the motor works discontinuously due to external electromagnetic interference, sometimes connected and sometimes disconnected, resulting in uneven printing output, affecting the printing effect, and resulting in printing failure

4. The printer cannot detect the output speed
