[0066] As shown in the drawings, Figure 1 With Figure 2 the first driving piece 25 drives the first lead screw 23 to rotate, and drives the second lead screw 24 to rotate synchronously, so as to stably move the movable piece 3. The first guide shaft 21 and the second guide shaft 22 guide the movable piece 3 to move along the width W direction, and the movable piece 3 can drive the swing piece 4 to move along the length L direction. When the swing piece 4 swings, it drives the rotating piece 5 to move synchronously, and the rotating piece 5 can rotate relative to the swing piece 4.

[0068] In work, the first driving piece 25 drives the first lead screw 23 to rotate, the first lead screw 23 drives the first pulley 28 to rotate, the first pulley 28 drives the second pulley 29 to rotate through the first transmission belt 281, and the second pulley 29 drives the second lead screw 24 to rotate, so that the first lead screw 23 and the second lead screw 24 rotate synchronously, and then drive the moving piece 3 to move, so that the movement of the moving piece 3 is more stable. Under the guidance of the first guide shaft 21 and the second guide shaft 22, the moving piece 3 moves along the width W direction.

[0069] The moving piece 3 of the scheme comprises: a third support frame 31, which is movably sleeved on the first guide shaft 21, and the first lead screw 23 is threadedly connected with the third support frame 31; a fourth support frame 32, which is movably sleeved on the second guide shaft 22, and the second lead screw 24 is threadedly connected with the fourth support frame 32; a third guide shaft 33, one end of which is inserted on the third support frame 31, and the other end of which is inserted on the fourth support frame 32; a fourth guide shaft 34, one end of which is inserted on the third support frame 31, and the other end of which is inserted on the fourth support frame 32, and the fourth guide column and the third guide column are arranged in parallel along the length L direction of the base 1; a moving frame 35, one end of which is movably sleeved on the third guide shaft 33, and the other end of which is movably sleeved on the fourth guide shaft 34; a second driving piece 36, which is arranged on the third support frame 31; and a third lead screw 37, which is connected with the output shaft of the second driving piece 36, and is threadedly connected with the moving frame 35, and the second driving piece 36 drives the third lead screw 37 to rotate, so as to drive the moving frame 35 to move along the length L direction.

[0070] As Figure 2As shown, the first screw rod 23 drives the third support frame 31 to move, and the first guide shaft 21 guides the third support frame 31 to move along the width W direction; at the same time, the second screw rod 24 drives the fourth support frame 32 to move, and the second guide shaft 22 guides the fourth support frame 32 to move along the width W direction, so as to ensure that the movable part 3 moves stably along the width W direction. The second driving part 36 drives the third screw rod 37 to rotate, and the third screw rod 37 drives the moving frame 35 to move, and under the guidance of the third guide shaft 33 and the fourth guide shaft 34, the moving frame 35 moves along the length L direction.

[0071] The moving frame 35 of the scheme extends along the height H direction to form an arc-shaped support 38, and the arc-shaped support 38 is provided with an arc-shaped first arc-shaped part 381 and a second arc-shaped part 382. The first arc-shaped part 381 and the second arc-shaped part 382 form a rotating space therebetween, and the rotating space is used to provide a space for the swing arm 41 to rotate.

[0072] The first arc-shaped part 381 and the second arc-shaped part 382 are arc-shaped structures, and a rotating space is formed between the two. When the swing arm 41 swings, the rotating space provides sufficient space for the swing arm 41 to swing, avoiding collision between the swing arm 41 and the arc-shaped support 38 when the swing arm 41 swings, thereby preventing damage to the swing arm 41 and the arc-shaped support 38.

[0073] The swing part 4 of the scheme comprises: a third pulley 42 rotatably arranged on the moving frame 35; a third driving part 43 arranged on the moving frame 35; a second transmission belt 44, one end of which is movably sleeved on the output end of the third driving part 43, and the other end of which is movably sleeved on the third pulley 42; a first bearing 45 inserted into the moving frame 35; a first connecting part 46 passing through the first bearing 45 and the swing arm 41, and connected to the third pulley 42, and the swing arm 41 is sleeved on the first connecting part 46; the third driving part 43 drives the second transmission belt 44 to rotate, for driving the third pulley 42 to rotate; the moving frame 35 extends along the width W direction to form a first support 39, and the third driving part 43 is arranged on the first support 39.

[0074] As shown in the figure, Figure 3 The third driving part 43 drives the second transmission belt 44 to rotate, the second transmission belt 44 drives the third pulley 42 to rotate, and the third pulley 42 in turn drives the first connecting part 46 and the inner ring of the first bearing 45 to rotate. The first connecting part 46 drives the swing arm 41 to swing, and the swing arm 41 in turn drives the rotating part 5 to swing synchronously, so as to change the angle of the rotating disc 51 relative to the first nozzle 61 and the second nozzle 62.

[0075] The rotating component 5 of this design includes: a second bearing 52, which is inserted into the rocker arm 41, and the inner ring of the second bearing 52 is fixedly connected to the turntable 51; a fourth pulley 53, which is sleeved on the lower end of the rotating component 5; a second connecting member 54, which is inserted into the rocker arm 41; a third bearing 55, which is inserted into the movable frame 35, and the second connecting member 54 is inserted into the third bearing 55; a second bracket 56, through which the second connecting member 54 passes in sequence and passes through the rocker arm 41 and the third bearing 55, and is connected to the second bracket 56; a fourth driving member 57, which is mounted on the second bracket 56; and a third transmission belt 58, one end of which is movably sleeved on the output end of the fourth driving member 57, and the other end of which is sleeved on the fourth pulley 53. The fourth driving member 57 drives the third transmission belt 58 to rotate, thereby driving the fourth pulley 53 to rotate.

[0076] like Figure 3 As shown, the third driving member 43 drives the second transmission belt 44 to rotate, the second transmission belt 44 drives the third pulley 42 to rotate, and the third pulley 42 in turn drives the inner ring of the first connecting member 46 and the first bearing 45 to rotate. The first connecting member 46 drives the rocker arm 41 to swing, and the rocker arm 41 in turn drives the second bracket 56 and the fourth pulley 53 to swing synchronously, thereby ensuring that the relative position of the fourth driving member 57 and the fourth pulley 53 set on the second bracket 56 remains unchanged, and preventing the third transmission belt 58 from getting tangled or knotted. The fourth driving member 57 drives the third transmission belt 58 to rotate, the third transmission belt 58 drives the fourth pulley 53 to rotate, the fourth pulley 53 in turn drives the inner ring of the third bearing 55 to rotate, and the inner ring of the third bearing 55 drives the turntable 51 to rotate.

[0078] The fifth drive unit 64 drives the fourth lead screw 65 to rotate, and the fourth lead screw 65 drives the support block 66 to move. Under the guidance of the guide post 67, the support block 66 moves along the height H direction, and drives the first nozzle 61 and the second nozzle 62 to move together along the height H direction. The first nozzle 61 and the second nozzle 62 can spray materials of different colors, thereby realizing the two-color printing function.

[0079] This solution also includes a sensor 7, which comprises:

[0080] The first sensor 71 is arranged on the base 1 and faces the fourth support frame 32, and is used to detect the position of the fourth support frame 32; the second sensor 72 is arranged on the fourth support frame 32 and faces the moving frame 35, and is used to detect the position of the moving frame 35; the first sensing block 73 is formed by the extension of the rocker arm 41 along the height H direction; the third sensor 74 is arranged on the moving frame 35 and corresponds to the first sensing block 73; the second sensing block 75 is formed by the extension of the fourth pulley 53 along the length L direction; the fourth sensor 76 is arranged on the rocker arm 41 and corresponds to the second sensing block 75; and the fifth sensor 77 is arranged on the fifth support frame 63 and faces the support block 66, and is used to detect the position of the support block 66.

[0081] Before the printer prints, the rotary disc 51, the first nozzle 61, the second nozzle 62, the movable part 3 and the rocker arm 41 need to be zeroed.

[0082] The first sensor 71 detects the position of the fourth support frame 32. The first driving part 25 drives the first lead screw 23 to rotate, and the second lead screw 24 is synchronously rotated, so as to drive the fourth support frame 32 to move and zero it.

[0083] The second sensor 72 detects the position of the moving frame 35. The second driving part 36 drives the third lead screw 37 to rotate, and the moving frame 35 is moved, so as to zero the moving frame 35 and finally zero the movable part 3.

[0084] The third sensor 74 detects the position of the first sensing block 73. The third driving part 43 drives the second transmission belt 44 to rotate, and the third pulley 42 is rotated, so as to drive the first connecting part 46 and the inner ring of the first bearing 45 to rotate, the first connecting part 46 drives the rocker arm 41 to swing, so as to align the first sensing block 73 with the third sensor 74, and thus zero the rocker arm 41.

[0085] The fourth sensor 76 detects the position of the second sensing block 75. The fourth driving part 57 drives the third transmission belt 58 to rotate, and the fourth pulley 53 is rotated, so as to drive the inner ring of the third bearing 55 to rotate, and the inner ring of the third bearing 55 drives the rotary disc 51 to rotate, so as to align the second sensing block 75 with the fourth sensor 76, and thus zero the rotary disc 51.

[0086] The fifth sensor 77 is used to detect the position of the support block 66. The fifth driving member 64 drives the fourth screw rod 65 to rotate, and the fourth screw rod 65 drives the support block 66 to move, and the support block 66 in turn drives the first nozzle 61 and the second nozzle 62 to move along the height H direction, so as to be zeroed.

[0087] Through the above steps, it is ensured that all key components return to the preset starting position, and the printing task is ready to start.

[0088] The first driving member 25 is arranged to drive the first screw rod 23 to rotate, and the second screw rod 24 is synchronously rotated, so as to stably move the movable member 3. The first guide shaft 21 and the second guide shaft 22 guide the movable member 3 to move along the width W direction, and the movable member 3 can drive the swing member 4 to move along the length L direction. When the swing member 4 swings, it drives the rotating member 5 to synchronously move, and the rotating member 5 can rotate relative to the swing member 4. The first nozzle 61 and the second nozzle 62 on the printing member 6 can move along the height H direction. Through the cooperation of the swing member 4 and the rotating member 5, the angle of the rotating disc 51 relative to the first nozzle 61 and the second nozzle 62 can be adjusted in real time, so as to ensure that the printing surface always maintains a horizontal or nearly horizontal state, avoids the newly deposited material from collapsing due to the action of gravity, thereby not needing to consume additional materials to print a support structure, and enables the printer to realize the integral high-precision forming of an internal and external hollow complex workpiece. The first nozzle 61 and the second nozzle 62 can spray different colors of materials, so as to realize a double-color printing function.
