[0025] Specifically, referring to Figure 3 The cleaning mechanism includes a concave rod 310, a sliding rod 320, a connecting plate 330, a mounting box 340, a compression spring 350, a sliding plate 360, and a cleaning scraper 370. One side of the front and rear connecting rods 300 is fixedly connected with the concave rod 310. The outer side wall of the concave rod 310 is slidingly connected with the sliding rod 320. The top of the left and right sliding rods 320 is fixedly connected with the connecting plate 330. The bottom middle part of the connecting plate 330 is fixedly connected with the mounting box 340. The inner cavity top of the mounting box 340 is uniformly fixedly connected with the compression spring 350. The bottom end of the compression spring 350 is fixedly connected with the sliding plate 360. The bottom middle part of the sliding plate 360 is fixedly connected with the cleaning scraper 370. By pulling the connecting plate 330 forward, one side of the printing table 200 extrudes the inclined surface of the cleaning scraper 370, causing the cleaning scraper 370 to move upward and extrude the compression spring 350. When the cleaning scraper 370 contacts the top of the printing table 200, the cleaning scraper 370 tightly adheres to the printing table 200 due to the counterforce of the compression spring 350. Continue to pull the connecting plate 330 forward to cause the cleaning scraper 370 to scrape off the impurities on the printing table 200, thereby avoiding cleaning after finding tools manually, making cleaning simple and convenient, and cleaning more quickly, improving cleaning efficiency and the practicality of the device.

When the inclined surface of the cleaning scraper 370 contacts one side of the printing table 200, the cleaning scraper 370 is extruded to shrink.

[0027] Notably, referring to Figure 4 The heat dissipation mechanism includes a filter screen 420, a heat dissipation fin 430, a heat conduction plate 440, a connecting frame 450, and a heat dissipation fan 460. The inner side wall of the ventilation opening 410 is fixedly connected with the filter screen 420. The top of the installation cavity 400 is uniformly penetrated by the heat dissipation fin 430. The top of the heat dissipation fin 430 is fixedly connected with the heat conduction plate 440. The front and rear of the inner side wall of the installation cavity 400 is fixedly connected with the connecting frame 450. The mutually far sides of the two connecting frames 450 are uniformly fixedly connected with the heat dissipation fan 460. Through the contact of the heat conduction plate 440 and the printing table 200, the heat of the workpiece is transmitted to the heat conduction plate 440 through the printing table 200 during printing. The heat on the heat dissipation fin 430 is taken out through the ventilation opening 410 by starting the heat dissipation fan 460, thereby dissipating the heat of the workpiece during printing, accelerating the cooling efficiency of the workpiece, facilitating the rapid forming of the workpiece, improving the printing efficiency, filtering the gas by the filter screen 420 to avoid impurities from entering, and ensuring safety. The input end of the heat dissipation fan 460 is electrically connected with the output end of the external power supply. The air directions of the heat dissipation fans 460 at the front and rear are the same, so that the gas flows in one direction to generate a flow channel to take out the heat.

[0028] Working principle: during printing, the heat of the workpiece is transmitted to the heat conduction plate 440 through the printing table 200, and then transmitted to the heat dissipation fin 430. By starting the heat dissipation fan 460, gas flow is generated to generate an air duct to take out the heat on the heat dissipation fin 430, thereby dissipating the heat of the workpiece during printing, accelerating the cooling efficiency of the workpiece, facilitating the rapid forming of the workpiece, and improving the printing efficiency. After printing is completed, the workpiece is disassembled. When it is necessary to clean the printing table 200, the connecting plate 330 is pulled forward to move the sliding rod 320 on the recessed rod 310, and simultaneously drive the installation box 340 to move, so that one side of the printing table 200 extrudes the inclined surface of the cleaning scraper block 370 to move the cleaning scraper block 370 upward, drive the sliding plate 360 to move, and extrude the compression spring 350 to deform. When the cleaning scraper block 370 contacts the top of the printing table 200, the cleaning scraper block 370 is tightly attached to the printing table 200 by the reaction force of the compression spring 350. The cleaning scraper block 370 scrapes off the impurities on the printing table 200 by continuously pulling the connecting plate 330 forward, and cleaning is completed.
