Problems solved by technology

These waste waxes may block the nozzles and cause the print nozzles to fail to eject, so the print nozzles need to be cleaned regularly
The existing nozzle cleaning method uses manual cleaning.

Example Embodiment

[0053] Example 1

[0054] Such as Figure 1 to Figure 5 The nozzle cleaning system of a 3D printer shown is installed in a 3D printer. The 3D printer includes a printing platform 1, an x-axis component that realizes the movement of the printing platform 1 back and forth, a printing nozzle 3, and a z-axis component that realizes the up and down movement of the printing nozzle 3 4. Including a cleaning component for cleaning the nozzle and a collection component for collecting waste wax. The cleaning component is slidably connected to the x-axis component 2, and the collection component is installed on the z-axis component 4. After the cleaning assembly cleans the nozzle, adjust the positions of the collection assembly and the cleaning assembly through the x-axis assembly 2 and the z-axis assembly 4. The collection assembly automatically collects the waste wax in the cleaning assembly. The entire cleaning process is controlled by the control system, no manual operation is required...

Example Embodiment

[0073] Example 2

[0074] A nozzle cleaning system for a 3D printer based on Embodiment 1, the difference lies in the structure of the cleaning components. Such as Picture 10 As shown, the cleaning assembly also includes an autonomous motion mechanism. The autonomous motion mechanism includes a rotating motor 30 mounted on the support frame 7 and a rack 32 mounted on the X-axis assembly 2. The bottom of the rotating motor 30 is provided with a gear 31, and the rotating motor 30 The gear 31 is driven to rotate on the rack 32, thereby driving the cleaning assembly to move back and forth on the X-axis assembly 2. The top of the support frame 7 is fixed with a lifting motion component for lifting the waste pool 5, the lifting motion component is a jack structure, the opposite ends of the diamond bracket 34 are installed on the screw motor 33, when the screw motor 33 is working, the diamond bracket 34 is opposite The two ends of the two move inward or outward, thereby controlling th...

Abstract

The invention discloses a 3D printer spray head cleaning system, and is installed on a 3D printer. The 3D printer spray head cleaning system comprises a cleaning component used for cleaning a spray head, wherein the cleaning component comprises scraping plates used for cleaning the spray head, and a waste material pool used for containing waste materials cleaned from the spray head; and the scraping plates are installed in the water material pool. A cleaning method comprises the following steps that: under the driving of a printing platform or through an automatic movement mechanism, the cleaning component moves to be below the printing platform; the printing spray head extrudes waste wax in a wax cavity through air; the scraping plates scrape the waste materials on the bottom of the printing spray head; the cleaning component moves to be below the printing platform; and new wax enters the wax cavity to be subjected to printing injection, and the new wax is injected to the waste material pool. A whole cleaning process is controlled through a control system, a manual operation is not required, and cleaning efficiency is high.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a 3D printer nozzle cleaning system and a cleaning method thereof. Background technique [0002] 3D printers build three-dimensional models through additive manufacturing methods. Wax type 3D printer is a kind of additive manufacturing equipment. It uses blue wax as printing material and white wax as supporting material. It sprays high-temperature heated wax onto the printing platform, and builds models by layer-by-layer stacking. Due to the advantages of high precision and smooth surface of wax-sprayed 3D printing models, wax-sprayed 3D printers are widely used in jewelry, aerospace, engine and other manufacturing industries. The printing materials used in the wax spray 3D printer are white wax and blue wax. The wax is packed in a container, and the container is put into the ink supply assembly. The blue wax in the container flows into the ink supply assembly, and flows i...
