The working principle of the three-dimensional Braille bump printing method provided by the embodiment of the application is as follows:

inserting one end of the screen 100 to be manufactured into the strip-shaped groove 365, screwing the locking bolt 364, and pushing the clamping strip 362 to vertically move by the locking bolt 364 so that the clamping block 363 and the clamping strip 362 fix the screen 100 on the clamping plate 361; the rotating motor 230 drives the first drill 240 and the second drill 250 to rotate simultaneously, the lifting motor drives the rotating motor 230, the first drill 240 and the second drill 250 to move vertically, the first motor 310 drives the first screw 330 to rotate, the first screw 330 drives the supporting block 350 to move horizontally, the second motor 320 drives the second screw 340 to rotate, and the second screw 340 drives the clamping plate 361 to move horizontally, so that the positions of the screen 100, which need to be drilled and the concave points, move to the lower side of the second drill 250.

The first drill 240 and the second drill 250 slide to approach the screen 100, the second drill 250 drills a hole on the screen 100 to fix the positions of the screen 100 and the first drill 240, and the lifting motor drives the first drill 240 to move downwards to drill a concave point on the position of the hole by the first drill 240; both ends of the screen 100 are respectively wound around and fixed to the two turntables 431, so that the screen 100 is in a circular tube shape, and the lower wall of the squeegee 440 is in sliding contact with the inner wall of the screen 100.

Paper is placed on a feeding plate 761 in a feeding box 760, a pushing spring 762 pushes the feeding plate 761 to move upwards, so that the paper is contacted with a rubber roller 730, a driving motor 720 drives the rubber roller 730 to rotate, the rubber roller 730 pushes the topmost paper onto a conveyor belt 710, a fifth motor 711 drives a rotating shaft to rotate, the rotating shaft drives the conveyor belt 710 to rotate, the conveyor belt 710 conveys the paper below a screen 100,

the third motor 610 drives the third screw 620 to rotate, so that the driving block 630 moves on the bar-shaped rod 640, the driving block 630 drives the rotating rod 441 to move, the rotating gear 430 on the rotating rod 441 rotates on the rack 420, the rotating gear 430 drives the rotating disc 431 and the screen 100 to rotate, and simultaneously the scraper 440 horizontally translates on the rack 420, and the rectangular block 450 can limit the rotation of the scraper 440, so that the scraper 440 and the inner wall of the screen 100 relatively slide.

When the ink inlet 511 is communicated with the first inking channel 461, the ink pump 530 is started, the ink pump 530 presses ink into the ink inlet pipe 520, the ink enters the first inking channel 461 through the ink inlet 511, the ink flows out from the first ink outlet 463 and falls onto the inner wall of the screen 100, the scraper 440 presses the ink into the hole, and when the screen 100 rotates on a paper, the ink flows out of the hole and is coated on the paper.

When the rectangular block 450 moves to one end of the strip-shaped hole 651, the fixing rod 543 penetrates into the rectangular groove 451 and pushes the slider 510 to move, the balls 542 overcome the elastic force of the locking spring 541 and enter the accommodating groove 512 from the circular groove, so that the fixing rod 543 pushes the slider 510 to move, when the accommodating groove 512 aligns with another circular groove, under the action of the locking spring 541, the balls 542 are connected in the aligned circular groove, so that the ink inlet 511 is communicated with the second ink feeding channel 462, and therefore, ink can be coated on paper in the reciprocating rolling process of the screen 100, and the coating speed of the ink is increased.

After the paper is coated with the ink, the conveyor belt 710 conveys the paper to the lower side of the drying box 744, the electric fan 741 is started, the electric fan 741 conveys hot air formed in the drying box 744 downwards, the hot air downwards penetrates through the air deflectors 743, the hot air is blown to the ink through the air deflectors 743, the drying of the ink is accelerated, meanwhile, the paper with the dry ink is blown into the material receiving box 751, and the manufactured braille paper is collected.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
