The horizontal moving slide plate 303 is mounted on the reference flat plate 502 through the slide rail 302 to realize the translation in a printing working area, the horizontal moving slide plate 303 is connected with the motor 301 through a synchronous belt, and the motor 301 drives the scraper device 300 to move along the slide rail 302.
The invention also includes: a blade holder 305. The squeegee frame 305 is connected to the horizontal movement sled 303 via a swivel shaft 306, i.e., the squeegee frame 305 can swing on the horizontal movement sled 303. The horizontal movement slide 303 is coupled to the slide rail 302 to translate, and the squeegee frame 305 pivots about the pivot shaft 306. The blade holders 305 are provided with blades 304 on both sides, the two blades 304 being at an angle to each other.
The scraper frame 305 is equipped with scraper 304 in both sides, and when scraper assembly 300 is to one side scraping, one side scraper 304 is worked, and another side scraper 304 improves certain altitude and does not work, and when the switching-over, scraper frame 305 swings, and another side scraper 304 drops, and former working scraper 304 promotes, realizes the tool changing function, switches scraper 304 of scraper frame both sides promptly.
Mounting grooves are formed in two sides of the scraper frame 305, a blade mounting plate 326 is arranged in the mounting grooves, and two scrapers 304 are respectively mounted on two sides of the scraper frame 305 through the blade mounting plate 326.

As shown in fig. 7, the scraper frame 305 is provided with a bar-shaped groove 319, and the shift fork roller 317 is positioned in the bar-shaped groove 319 and can roll in the bar-shaped groove 319. When the scraper frame 305 drives the scraper 304 to reach the position of the striker 314, the striker 314 impacts the shifting fork 315, so that the bottom end of the shifting fork piston rod 316 swings to drive the shifting fork roller 317 to roll in the bar-shaped groove 319, the rolling shifting fork roller 317 applies thrust to the scraper frame 305, and the left-right shifting process of the shifting fork roller 317 shifts the scraper frame 305 to rotate, namely, the scraper frame 305 swings on the horizontal moving sliding plate 303, so that the scrapers 304 on two sides of the scraper frame 305 are switched.
The fork device further includes: the compression spring 320, one end of the compression spring 320 is connected with the shifting fork 315, the other end is connected with the shifting fork piston rod 316, and the compression spring 320 is always in a compression state. Due to the action of spring force in the shifting fork piston rod, the shifting fork device can firmly prop against the scraper frame 305 in the swinging process, so that the scraper frame 305 can firmly prop against after swinging, and the positioning function is realized. The fixing mode of the scraper frame 305 is more fastened and stable and is also more reliable through the compression springs 320.
The fork device further includes: support shaft 321, bearing 322 and fixed block 323. The bearing 322 is arranged in the shifting fork 315 and fixedly connected with the shifting fork 315, the bearing 322 is sleeved on the supporting shaft 321, and two ends of the supporting shaft 321 are fixedly connected with the horizontal moving sliding plate 303 through the fixed blocks 323. Thereby realizing that the scraper frame takes the horizontal moving sliding plate 303 as a rotation supporting point, but the horizontal moving sliding plate 303 is not influenced, and the structure is simple and stable.
The shifting fork roller 317 on the shifting fork device can roll in the bar-shaped groove 319, when the upper end of the shifting fork device is subjected to external force, the shifting fork device rotates around the rotating shaft, and due to the action of spring force in the shifting fork piston rod, the shifting fork device firmly abuts against the scraper frame, so that the scraper frame firmly abuts against the scraper frame after swinging, and the positioning function is realized. When the scraper moves to the other side, the above actions are repeated, and the automatic tool changing function is realized. After the scraper 304 completely penetrates through the printing table with the slurry, the clock pendulum is realized through the structural blade, the scraper on the other side falls down, the scraper on the original side is lifted, and the scraper returns to repeat the previous action with the residual material, so that the automatic feeding problem of the 3D printer is solved through the reciprocating action. The clearance between the working table and the scraper in use in the two scrapers is 0.1-0.3 mm.
The horizontal moving slide plate 303 is provided with a positioning screw 324 for adjusting the angle of the scraper frame 305, which is used for adjusting the angle of the scraper frame 305 and has the function of accurate limiting, thus ensuring the positioning precision and repeated positioning precision of each swing.
