Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D printing platform cleaning device. Background Technique

[0002] When the existing 3D printers print 3D models, there are often many residual materials after printing, including powders remaining on the platform and printed skirts, etc. These waste materials often remain on the printing platform and need to be cleaned in time to avoid affecting the forming quality of the 3D printing model, etc.

[0003] The existing 3D printer platform cleaning devices all adopt manual cleaning. Manual cleaning not only has low efficiency but also is not thorough. There is still a small amount of garbage or dust on the printer platform. When using the 3D printer to print an object, the printed object will touch such dust after being transported to the printing platform, thus polluting the surface of the printed object and affecting the appearance of the printed object.

[0004] At the same time, when the existing 3D printer platform cleaning device cleans the printer platform, the dust or paper scraps adhered to the platform surface can be cleaned off by a simple cleaning brush, etc. However, when the waste material has a high adhesion strength, it is easy to occur that the cleaning moving part cannot scrape the waste material, and then the waste material continues to adhere to the surface of the printing platform, resulting in the problem of unclean cleaning. Therefore, we propose a new 3D printing platform cleaning device. Content of the Utility Model

[0005] The main purpose of the utility model is to propose a 3D printing platform cleaning device, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a 3D printing platform cleaning device, including a printing platform, four corners of the top of the printing platform are fixedly connected with vertical plates, a moving component is arranged on the top of the printing platform, the moving component includes a threaded rod, a motor, a sliding rod, and a mounting frame. The threaded rod is rotatably connected to the opposite sides of the two vertical plates, one side of the vertical plate is fixedly connected with a motor, and the output end of the motor penetrates through the vertical plate and is fixedly connected with the threaded rod. The sliding rod is fixedly connected to the opposite sides of the other two vertical plates. An installation frame is slidably sleeved on the threaded rod and the sliding rod. The installation frame is meshed with the threaded rod through a threaded groove.

A waste material collection box is fixedly connected to the bottom of the printing platform. A box door is arranged on one side of the waste material collection box. Legs are fixedly connected to the four corners of the bottom of the printing platform.

[0007] As a further description of the above technical solution, through grooves one and two are symmetrically and penetratingly formed on the two side walls of the mounting frame respectively, and the through groove one and the through groove two are on the same horizontal line.

[0008] As a further description of the above technical solution, the cleaning assembly includes a first fixing frame, a brush, and a first fixing bolt. The first fixing frame is slidably connected to the inner cavity of the mounting frame. A plurality of brushes are uniformly and fixedly connected to the bottom of the first fixing frame. The two first fixing bolts penetrate through the through groove one to fixedly connect the first fixing frame to the inner cavity of the mounting frame.

[0009] As a further description of the above technical solution, the scraping assembly includes a second fixing frame, a scraper, and a second fixing bolt. The second fixing frame is rotationally and slidably connected to the inner cavity of the mounting frame. A scraper is fixedly connected to the bottom of the second fixing frame. The two second fixing bolts penetrate through the through groove two to fixedly connect the second fixing frame to the inner cavity of the mounting frame, and the second fixing frame is located on the side of the first fixing frame away from the blanking groove.

[0012] By arranging a cleaning assembly, a scraping assembly, a moving assembly, etc., when the residues on the printing platform are powder, dust, paper scraps, etc., the motor is started, the threaded rod rotates to drive the mounting frame to move along the directions of the threaded rod and the sliding rod, and the brush and the scraper can clean the powder, dust, and paper scraps on the top of the printing platform from the blanking groove to the inner cavity of the waste collection box. The brush and the scraper are used for double cleaning, with high cleaning quality, ensuring the cleanliness of the top of the printing platform and effectively saving labor.

[0013] By setting up a cleaning component, a scraping component, a cleaning component, a moving component, etc., when the attachment strength of waste on the printing platform is high and the waste cannot be scraped by the brush and the scraper, loosen the first fixing bolt, move the first fixing frame and the brush above the inner cavity of the mounting frame through the first through groove, and then tighten the first fixing bolt.

When it is necessary to adjust the angle between the scraping plate 5.2 and the printing platform 1, loosen the fixing bolts two 5.3, move and rotate the fixing frame two 5.1. When the scraping plate 5.2 is adjusted to an angle that is more convenient for scraping the waste material on the top of the printing platform 1, tighten the fixing bolts two 5.3.
