Embodiment

[0021] Embodiment: The worker installs the automatic blade device on the gantry of the FDM 3D printer through the fixing part a7 and the fixing part b8, and the installation height of the automatic blade device is higher than the height of the platform. After the device is fixed on the gantry, it can move along the Z-axis direction and the Y-axis direction along with the gantry. When it is necessary to shovel out the forming mold, the shovel device 1 first reduces the distance from the platform in the Z-axis direction until it contacts the shovel 3 with the platform. Continue to reduce the height of the automatic shovel device afterwards, the spring 6 is compressed, and the spring 6 indirectly applies a downward force to the shovel 6, so that the shovel 6 is closely attached to the platform. The gantry then moves in the direction of the Y axis, and relative displacement occurs with the forming model on the platform, and the model is removed.

Abstract

The invention discloses an automatic scraper knife device for an FDM type 3D printer. The automatic scraper knife device for the FDM type 3D printer comprises a scraper knife device body and guide devices, and the guide devices are fixedly arranged at the two ends of the scraper knife device body; the scraper knife device body comprises a scraper knife and a cross rod, and the scraper knife is embedded and fixed into the side face of the cross rod; each guide device body comprises a vertical rod, a spring, a fixing piece a, a fixing piece b and a sliding block, and each sliding block is of a hollow structure; the vertical rods penetrate through the hollow parts of the sliding blocks and are arranged in the sliding blocks; the springs penetrate through the vertical rods and are arranged above the sliding blocks; and the fixing pieces a are fixedly arranged at the upper ends of the vertical rods, and the fixing pieces b are fixedly arranged at the lower ends of the vertical rods. According to the automatic scraper knife device, products can be shoveled off from a platform under the unattended condition, practical labor is not needed, and continuous printing of the products can be achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to an automatic blade device for an FDM 3D printer. Background technique [0002] FDM 3D printer is a printing technology of 3D printer mainly through fused deposition modeling. FDM 3D printers generally take less time to print TPU materials. After each print is completed, a human being is required to remove the finished product. This increases a lot of labor costs. Therefore, there is an urgent need in the industry for a device that can automatically remove finished products to realize continuous printing by FDM 3D printers. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an automatic shovel device for an FDM type 3D printer, including a shovel device and a guide device, and the two ends of the shovel device are fixedly provided with the guide device; The shovel device includes a sho...
