Embodiment Construction
[0020] like Figure 1~Figure 3 As shown, the present invention includes a mechanical part and an electronic part, wherein the mechanical part includes a roller 1 , a roller bracket 2 , a bearing 3 and a bearing bracket 4 ; the electronic part includes a circuit board 9 , an infrared transmitter 7 and an infrared receiver 8 .
[0021] The roller 1 is installed on the roller bracket 2 through the roller shaft, and the roller 1 is connected with the bearing 3 through the roller shaft, and the bearing 3 is installed on the bearing bracket 4 . A through hole 6 is respectively opened in the directions of 0°, 90°, 180°, and 270° of the roller 1, and the diameters of the four through holes 6 are the same. In other embodiments, six or eight through holes can be provided. The roller 1 is a passive wheel, which rotates with the normal movement of the filament 5 during the working process of the 3D printer. When the roller 1 rotates normally, its speed is constant. If the filament 5 is ab...

The invention provides a digital information flow command and control device in a 3D printer. The structure of the digital information flow command and control device comprises a bearing support, a bearing, a roller support, a roller, an infrared transmitter, an infrared receiver and a circuit board. The roller is uniformly provided with a plurality of through holes. The infrared transmitter and the infrared receiver are located on two sides of the roller respectively, and the connection line of the infrared transmitter and the infrared receiver passes through the through holes in the roller. When the roller is in normal rotation, the time that the infrared receiver can be used to receive infrared light signals through any through hole in the roller is a fixed time, and the time that the infrared receiver cannot be used to receive the infrared light signals through the portion of any two adjacent through holes in the roller is also a fixed time, the circuit board is used to control the mainboard to stop reading or normally read data in a SD card according to the time length that the infrared receiver can be used to receive the infrared light signals and the time length that the infrared receiver cannot be used to receive the infrared light signals so as to control the suspended transmission or normal transmission of the digital information flow to realize the printing stopping or printing starting.
Description
technical field [0001] The invention relates to a control device in a 3D printer, in particular to a digital information flow command and control device in a 3D printer. Background technique [0002] A 3D printer is a machine with rapid prototyping technology. It is based on a digital model file and uses bondable materials such as powdered metal or plastic to construct the shape of an object by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and now it is gradually being used in the direct manufacture of some products. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. Its working principle is: put data and raw materials (or consumables) into the 3D printer, and the machine will build the product layer by layer according to the program. The printed product can be used immediately. [0003] When the 3D printer is working, th...
