Problems solved by technology

[0005] The present invention provides a detachable 3D printer nozzle with convenient internal cleaning and capable of double-pass material spraying, which solves the problems of the existing 3D printer nozzles that are inconvenient for internal cleaning and can only perform single-pass material spraying
When in use, the present invention is installed on the storage box in a manner of moving perpendicular to the length direction of the nozzle body. When the present invention moves back and forth (that is, two-way), the resin can be sprayed and filled into the storage box, and the scraper can immediately discharge the resin while discharging the resin. The upper surface of the resin is scraped flat, thus avoiding the problem of the resin layer being exposed to the air for a long time and being cured by ultraviolet rays, resulting in a decrease in fluidity

Embodiment 2

[0041] Embodiment two, the difference with embodiment one is:

[0042] see image 3 , The opening and closing valve mechanism 4 also includes a motor 8 and a power switching mechanism 2 . The motor 8 includes a motor housing 81 and a motor shaft 82 . The motor housing 81 is fixedly connected with the grip bar 42 . The motor casing 81 is provided with the connection terminal 3 . The drive shaft 41 is connected to one end of the motor shaft 82 through a speed reducer 83 . The other end of the motor shaft 82 passes through the handle bar 42 .

[0043] see Figure 4 , The power switching mechanism 2 includes a switch 21 , a pressing rod 22 , a latch 23 and an insertion spring 24 . The switch 21 and the pressing rod 22 are located on both sides of the latch 23 . The switch 21 is fixed in the handle bar 42 . Switch 21 is a push switch, because the control motor 8 starts and stops. The pressing rod 22 passes through the grip rod 42 . The latch 23 is slidably connected in th...

Abstract

The invention relates to printers.A detachable 3D printer spray head comprises a spray head body, wherein the spray head body is provided with a nozzle and an inlet.The detachable 3D printer spray head is characterized in that the spray head body is in the shape of a long strip, the nozzle is a gap extending in the length direction of the spray head body, the spray head body is provided with two scrapers, an expansion groove is formed between the two scrapers, the outlet end of the nozzle is located in the expansion groove, the spray head body comprises two half portions detachably connected, and the nozzle is arranged on the connecting surface of the two half portions.According to the detachable 3D printer spray head, internal cleaning is convenient, round-trip spraying can be achieved, and the problems of existing 3D printer spray heads that internal cleaning is inconvenient, and only single-trip spraying can be achieved are solved.

Description

technical field [0001] The invention relates to a printer, in particular to a detachable nozzle of a 3D printer. Background technique [0002] A 3D printer is a device that prints based on the cumulative forming technology of the discrete accumulation principle. It integrates computer-aided design (CAD) and computer-aided manufacturing (CAM) with the help of modern means such as computer, laser, precision transmission and numerical control, and can directly manufacture products in a short time according to the three-dimensional model constructed on the computer. model or sample. [0003] There are many ways to form 3D printers. One of them is to use photosensitive resin as the raw material. The 3D model of the part designed on the computer is triangulated on the surface, stored in STL file format, and processed in layers to obtain the cross-section of each layer. The two-dimensional profile information, and then the computer controls the DLP projector to project the two-di...
