Embodiment Construction

[0028] 3D printer with cleaning function, its structure and working principle are as follows: figure 1 .

[0029] 1. Equipment composition

[0030] 3D printer three-axis motion platform, ink cartridge, cleaning ink cartridge, cleaning pipe, waste liquid recovery device, related supporting control components, electro-pneumatic control part of the equipment circuit. The overall structure of the printer is as follows figure 2 shown.

[0031] 2. Working principle

[0032] (1) In order to achieve multi-material printing with one nozzle, the cleaning process is called before changing the material, and the pre-spraying process is called after cleaning, so that the printer is at the initial point of benign work. The pre-spraying process is to switch to the printing working state at the initial point, flush the pipeline and nozzle with printing materials, ensure the degree of wetting of the nozzle, and ensure the printing accuracy and effect of the printing starting point.

Abstract

The invention discloses a micro spray 3D printing device capable of automatically washing a sprayer as well as a working method of the micro spray 3D printing device. The 3D printing device comprises a printing base plate, the sprayer, an ink box, a waste liquid recycling tank and a sprayer washing device, wherein the sprayer washing device comprises a washing liquid ink box, a washing pipe and a washing tank; washing liquid is contained in the washing liquid ink box; a material box and the washing liquid ink box are arranged side by side; a detachable pipeline is arranged at the lower part of the box; a gate valve is arranged in the middle of the pipeline; a tee electromagnetic valve is arranged at the lower part of the material ink box pipeline; the other two ends of the tee electromagnetic valve are connected with pipelines, one pipeline is connected with the sprayer; a gate valve is arranged in the middle of the other pipeline and the other pipeline is connected with the pipeline at the lower end of the washing liquid ink box; the washing tank and the liquid recycling tank are movably connected on the cavity wall of the printer; the printing base plate is arranged at the center of the bottom of the cavity of the printer; the number of the material ink boxes is greater than 2; the washing liquid is contained in the ink cavity of the washing ink box; the residual printing machine in the sprayer can be dissolved by the special chemical component of the washing liquid. According to the 3D printing device, the washing ink box and the material ink boxes are arranged on the printer side by side; the work status of the control system is switched through the tee valve; the washing procedure can be invoked by a printing program to complete washing operation.

Description

technical field [0001] The invention relates to the technical field of a three-dimensional printer spray head system, a cleaning device and droplet spraying. Background technique [0002] A method and device for cleaning printer nozzles and a combined print head and printer (application number: CN 200310122891) published in Chinese patent documents are characterized in that, during the use of a digital inkjet printer, a interrupts the printing operation and moves the nozzle out Printing area; b. Use compressed air as the power to force the ink to flow out of the nozzle for a period of time to clean the nozzle; c. Wait for a period of time after the nozzle cleaning is completed, then move the nozzle back to the printing area and restart the printing operation. The compressed air is generated by an air pump, and after passing through the main air circuit, it is transported through each branch air circuit and enters the ink supply bottles of each color, and is connected with ea...
