[0019] like Figure 1 As shown, this embodiment proposes a 3D printer cleaning device, including a mixing tank body 1, with an inlet pipe connected to the top of the mixing tank body 1, a cleaning mechanism 2 for cleaning the 3D printer tray being provided on the outside of the mixing tank body 1, and a driven component 3 for improving the cleaning effect of the cleaning mechanism 2 being provided inside the cleaning mechanism 2. like Figure 1 , Figure 3 and Figure 5As shown, the cleaning mechanism 2 includes a water pump 201 fixedly connected to the bottom of the mixing tank body 1. The input end of the water pump 201 is connected to the inside of the mixing tank body 1. The water pump 201 is used to draw liquid out of the mixing tank body 1. The output end of the water pump 201 is connected to a connecting pipe 202. A hose 203 is threadedly connected to the top of the connecting pipe 202. A horizontal pipe 204 is connected to the top of the hose 203. A nozzle 205 is connected to one end of the horizontal pipe 204. The nozzle 205 is used to discharge the cleaning liquid drawn out by the water pump 201. A baffle frame 206 is fixedly connected to the outer wall of the horizontal pipe 204 near the nozzle 205. A motor 207 is bolted to the top of the baffle frame 206. A first turntable 208 is fixedly connected to the output end of the motor 207. Several first bristles 209 are fixedly connected to the bottom of the first turntable 208. The first turntable 208 and the first brush 209 are rotated to clean the external tray. A scraper 210 is provided on one side of the blocking frame 206. The scraper 210 is used to scrape off the attachments that are difficult to clean. An adjustment component 211 for adjusting the height of the scraper 210 is provided on the outside of the scraper 210. When it is necessary to clean the external tray, the cleaning liquid can be poured into the mixing tank body 1 through the liquid inlet pipe. Then, the water pump 201 is started. The water pump 201 draws the cleaning liquid into the connecting pipe 202, the hose 203, the horizontal pipe 204 and the nozzle 205 in sequence. Then, it is discharged to the surface of the tray through the nozzle 205. Then, the motor 207 is started. The motor 207 drives the first turntable 208 and the first brush 209 to rotate, thereby cleaning the tray. If there are some attachments on the tray that are difficult to clean, they can be scraped off by the scraper 210.

[0020] like Figure 5 As shown, the adjustment assembly 211 includes a horizontal plate 21101 fixedly connected to the outer wall of the blocking frame 206. A lead screw 21102 is threadedly connected to the inside of the horizontal plate 21101. Rotation of the lead screw 21102 can drive the scraper 210 to rise or fall. Stable rods 21103 are fixedly connected to both ends of the top of the scraper 210. The bottom of the lead screw 21102 is rotatably connected to the top of the scraper 210. The top of the stable rod 21103 passes through the horizontal plate 21101 and is slidably connected to the horizontal plate 21101. When cleaning hard-to-clean attachments with the scraper 210, it is only necessary to manually rotate the lead screw 21102 to drive the scraper 210 down along the stable rod 21103 to the designated position. Then, the horizontal tube 204 can be moved to quickly scrape off the attachments through the scraper 210. When the scraper 210 is no longer needed, the lead screw 21102 is rotated in the opposite direction to make the scraper 210 rise.

[0021] like Figure 4As shown, the driven component 3 includes a rotating rod 301 rotatably connected to the bottom of the blocking frame 206. A first pulley 302 is fixedly connected to the outer wall of the rotating rod 301. A second turntable 303 is fixedly connected to the bottom of the rotating rod 301. A plurality of second bristles 304 are provided at the bottom of the second turntable 303. A second pulley 305 is fixedly connected to the output end of the motor 207. A belt 306 is provided on the outside of the first pulley 302 and the second pulley 305. When the motor 207 drives the first turntable 208 to rotate, the second turntable 303 and the second bristles 304 can be driven to rotate through the cooperation of the first pulley 302, the second pulley 305 and the belt 306, thereby increasing the cleaning area and thus increasing the cleaning speed.

[0022] like Figure 3 As shown, a cylinder 4 is provided at the end of the horizontal tube 204 away from the blocking frame 206. An electric push rod 5 is fixedly connected to the inner wall of the cylinder 4. The telescopic end of the electric push rod 5 is fixedly connected to one end of the horizontal tube 204. If the worker feels that the horizontal tube 204 is too short during use, the electric push rod 5 can be activated. The electric push rod 5 drives the horizontal tube 204 to move along the inside of the cylinder 4, which makes it easier for the worker to operate the device.

[0023] like Figure 1 As shown, a protective shell 6 is bolted to the bottom of the mixing tank body 1. Four self-locking casters 7 are provided at the bottom of the protective shell 6. The water pump 201 is located inside the protective shell 6. The device can be easily moved by the self-locking casters 7.

[0024] like Figure 1 As shown, an observation window 8 is provided on the side wall of the mixing tank body 1 to facilitate workers to observe the remaining water level inside the mixing tank body 1. Through the observation window 8, workers can easily understand the remaining water level inside the mixing tank body 1 so that they can add cleaning fluid to it in a timely manner.

[0025] like Figure 3 As shown, a stirring rod 9 is rotatably connected inside the mixing tank body 1, and a motor 10 is bolted to the top of the mixing tank body 1. The output end of the motor 10 is fixedly connected to the top of the stirring rod 9. When the cleaning liquid is added, the motor 10 is started, and the motor 10 drives the stirring rod 9 to rotate, thereby uniformly mixing the cleaning liquid and water.

[0026] Specifically, when using this 3D printer cleaning device: if cleaning of the external tray is required, the cleaning fluid can be poured into the mixing tank body 1 through the inlet pipe. Then, the water pump 201 is started, and the water pump 201 sequentially draws the cleaning fluid into the connecting pipe 202, hose 203, horizontal pipe 204, and nozzle 205. The fluid is then discharged onto the tray surface through the nozzle 205. Next, the motor 207 is started, driving the first turntable 208 and the first brush 209 to rotate. Through the coordinated use of the first pulley 302, the second pulley 305, and the belt 306, the second turntable 303 and the second brush 304 can be rotated, thereby increasing the cleaning area (e.g., ...). Figure 3 and Figure 4 (As shown), if there are some difficult-to-clean attachments on the tray, simply rotate the screw 21102 manually to lower the scraper 210 along the stabilizer 21103 to the designated position. Then, move the horizontal tube 204 to quickly scrape off the attachments using the scraper 210. To cancel the use of the scraper 210, rotate the screw 21102 in the opposite direction to raise the scraper 210 (as shown). Figure 5 (As shown).

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
