Description

Technical Field

[0001] This utility model relates to the field of 3D printers, and more particularly to a cleaning device for a 3D printer work platform. Background Technology

[0002] A 3D printer is a device that creates three-dimensional objects by adding materials layer by layer. It is widely used in various fields such as manufacturing, medical, construction, education, and art. A 3D printer's worktable cleaning device is an important component to ensure a smooth printing process. This device keeps the printing platform clean after printing, thereby improving print quality and results.

[0003] A search revealed Chinese Patent Publication No. CN221660112U, which discloses a cleaning device for a 3D printer's work platform. The device includes a base plate on which a cleaning mechanism is mounted. This cleaning mechanism comprises a bracket, mounting plate, mounting frame, telescopic rod, support rod, heating rod, scraper, brush, motor, top plate, control panel, moving mechanism, and clamping mechanism. This invention addresses the problems of desktop fused deposition modeling 3D printers manufactured in the early stages of 3D printing technology development. These printers, due to their early production and less-than-perfect functionality, often experienced model misalignment or warping on the work platform during printing. To solve this problem, these 3D printers typically applied a layer of glue to the work platform to prevent misalignment or warping. However, over time, the glue buildup on the work platform led to instability at the bottom of the platform, resulting in deformed printed models. Furthermore, cleaning the glue was extremely difficult, time-consuming, and labor-intensive.

[0004] While the aforementioned device can clean glue and other residues on the work platform, its scraper position is relatively fixed, and the cleaning device can only move along the threaded rod. Furthermore, the height of the clamping plate is significantly higher than the clamped work platform. This results in incomplete cleaning if the scraper length is greater than the work platform to be cleaned, or if the scraper length is less than the area to be cleaned on the work platform, making it impractical. Therefore, a cleaning device for the 3D printer work platform is proposed to solve the above problems. Utility Model Content

A connecting block 55 is fixedly connected to the bottom of the connecting rod 54, which is used to connect the cleaning shovel 56. Two cleaning shovels 56 are fixedly connected to the bottom of the connecting block 55. The two cleaning shovels 56 are mirror images of each other. The cleaning shovels 56 have a certain curvature so that they can better fit the work platform and clean it. Connecting frames 52 are fixedly connected to the front and rear of the second guide block 51, which are used to connect the cleaning head 53. The cleaning head 53 is fixedly connected to the middle of the connecting frame 52, which is connected to the vacuuming equipment through a hose to collect and clean the adhesive block under cleaning.

[0035] Please see Figure 4 - Figure 5 The positioning component 7 includes a housing 72 for connecting various parts. The housing 72 is fixedly connected to the base plate 1. A cover plate 71 is fixedly connected to the top of the housing 72 for engaging with the housing 72. A slider 75 is slidably connected to the middle of the housing 72 for connecting various parts. Support rods 76 are movably connected to the left and right sides of the top surface of the slider 75 for connecting various parts. A connecting plate 77 is movably connected to the side of the support rod 76 away from the slider 75 for engaging with and driving the moving block 78 to move. A moving block 78 is fixedly connected to the upper side of the two connecting plates 77 that are far apart from each other. The movable block 78 is used to move the limiting plate 79. The movable block 78 is slidably connected to the slide 61. The top of the movable block 78 is fixedly connected to the limiting plate 79, which is used to fix the work platform. The positioning component 7 also includes a cylinder 73, which is used to drive the positioning component 7. The cylinder 73 is fixedly connected to the rear side of the housing 6. The output end of the cylinder 73 is movably connected to a pneumatic rod 74, which is used to adjust the position of the slider 75. The pneumatic rod 74 passes through the housing 6 and the shell 72 and is movably connected to the housing 6 and the shell 72.

[0037] Working principle: In use, place the work platform plate to be cleaned onto the outer casing 6, then turn on the cylinder 73. The cylinder 73 will move the air rod 74, which in turn will move the connected slider 75 within the slide groove 721. The slider 75 will then move one end of the support rod 76 connected to it. Since the other end of the support rod 76 is connected to the connecting plate 77, when the support rod 76 moves, it will move the connecting plate 77 within the connecting groove 722. The moving block 78 connected to the connecting plate 77 will then slide within the slide opening 61. The two moving blocks 78 will then move the two limiting plates 79 closer together, thereby clamping and fixing the work platform plate. Then, the heating plate 4 can be turned on to heat the residual colloid on the work platform plate. This makes it easier to detach from the work platform during subsequent cleaning. After heating is complete, the heating plate 4 can be turned off. Then, the first guide block 32 moves on the longitudinal guide rail 31, thereby driving the upright 33 to move. The transverse guide rail 34 connected to the upright 33 will move forward or backward accordingly. Then, according to the size of the work platform, the second guide block 51 drives the entire cleaning assembly 5 to move to a suitable position. Then, the cleaning shovel 56 can move forward or backward on the work platform through the transverse guide rail 34 that moves back and forth. The second guide block 51 can drive the cleaning assembly 5 to move left or right, thereby thoroughly cleaning the colloid on the work platform. During cleaning, the vacuum cleaner is turned on to give the cleaning head 53 suction power, and the cleaning head 53 will then suck up and clean the colloid cleaned by the cleaning shovel 56.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
