3d printer intelligent feeding detection mechanism

Abstract

The invention discloses an intelligent feeding detection mechanism for a 3D printer, which includes a channel for printing materials to pass through, and also includes a feeding sensor and a feeding speed sensor, and the signal receiving ends of the feeding sensor and the feeding speed sensor are both Connected with the channel, the feeding sensor is used to know whether there is printing material passing through the channel, and the feeding speed sensor is used to obtain the transmission speed of the printing material in the channel; a control system is also included, and the control system is used for: When the material sensor senses that there is no material or no material in the channel, it transmits the information to the control system, and the control system controls the printer to stop working and gives an alarm; and, when the feed speed sensor senses that the transmission speed of the printing material is zero , and transmit the signal to the control system, and the control system controls the printer to stop working. The invention can test whether there is a material blockage or lack of material during the printing process, and prompts to change the material, thus ensuring the success rate of printing.

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
