[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides an environmentally friendly ceramic slurry mixing device for a biological 3D printer, which has the following beneficial effects:

[0017] 1. The environmentally friendly ceramic slurry mixing device for the biological 3D printer is arranged at the bottom of the motor, and can use the power generation of the motor to drive the rotation of the first rotating shaft. The bottom of the first rotating shaft is fixedly connected to the polygonal plate, so when the first rotating shaft rotates, the polygonal plate will also rotate together. At this time, the three third gears located on the top of the polygonal plate will rotate on the outer surface of the second gear. At the same time, the three third gears also drive the fourth gear connected to the bottom to move. In addition to rotating the rotating device as a whole above the inside of the mixing tank, the stirring blades in the movable device can also rotate on their own to prevent the unevenness in the liquid components from having a negative impact on the quality of the process, thereby affecting the performance of the final product. Therefore, it will not only rotate and stir in the middle, but also increase the force to stir the slurry at the bottom in a small amplitude.

[0018] 2. The environmentally friendly ceramic slurry mixing device for the biological 3D printer, by connecting the second rotating shaft with the third gear, will drive the second rotating shaft to twist after the third gear rotates, the second rotating shaft is fixedly connected to the fourth gear, so the fourth gear will be connected to drive the outer fifth gear to rotate together, thereby realizing the internal circumferential movement of the mixing tank, and the stirring blades connected to the bottom of the three elliptical plates will also rotate with the power generation of the motor. The powder with large particle size will be deposited at the bottom of the mixing tank, while the powder with small particle size will float on it, resulting in slurry stratification. At this time, in addition to the large rotation of the three stirring blades, the separated slurries can also be mixed and stirred together by self-rotation, thereby improving the utilization rate of the slurry.

[0019] 3. The environmentally friendly ceramic slurry mixing device for the biological 3D printer can use the power of the dual-axis cylinder itself to pull the connecting blocks fixedly connected at the output shafts at both ends by arranging a dual-axis cylinder inside the support plate. Since the bottom of the connecting block is fixedly connected to the fixed plate, in addition to pushing the fixed plate to move to both sides, it will also drive the movement of the feed pipe connected to the bottom of the fixed plate, and move the slurry inside the two feed pipes to the bottom of the bottom stirring device for stirring, saving the need for manual secondary feeding, preventing the uniformity of the slurry from being affected, which will reduce the efficiency of the process and thus affect the overall efficiency of the production line.

[0020] 4. The environmentally friendly ceramic slurry mixing device used in the biological 3D printer can help the sliding block movably connected on the outer surface of the sliding rod to drive the fixed plate at the bottom to slide back and forth by setting two sliding rods at the bottom of the long strip. Under the pull of the two ends of the top double-axis cylinder, the feed pipes at the hollow parts of the two fixed plates will be stretched to both sides first. After putting in different slurries, the feed pipes will be driven to move to the top of the mixing tank by the expansion and contraction of the double-axis cylinder. Finally, the slurry inside the feed pipe will slide to the bottom of the stirring device for sufficient mixing and stirring. Good slurry uniformity can effectively improve process efficiency, save energy consumption and production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A feeding device 6 is provided on the top of the stirring device 5, and the top of the stirring device 5 is fixedly connected to the bottom of the feeding device 6. The feeding device 6 includes a double-axis cylinder 63. When the double-axis cylinder 63 extends back by its own power, it drives the fixed plate 67 connected to the bottom to slide on the sliding rod 65, thereby driving the feeding pipe 68 in the middle of the fixed plate 67 to first receive a part of the ceramic raw materials, and then return to its original position and pour it into the bottom of the corresponding stirring device 5 for unloading, so that the ceramic particles are evenly distributed in the slurry.

[0033] The rotating device 51 includes a motor 511, and the two ends of the top of the motor 511 are provided with a feeding device 6, and the two ends of the top of the motor 511 are fixedly connected to the bottom of the feeding device 6. A first rotating shaft 512 is provided at the bottom of the motor 511, and the bottom of the motor 511 is movably connected to the top of the first rotating shaft 512. A first gear 513 is provided on the outer surface of the first rotating shaft 512, and the outer surface of the first rotating shaft 512 is movably connected to the center of the first gear 513. A second gear 514 is provided at the bottom of the first rotating shaft 512, and the bottom of the first rotating shaft 512 is fixedly connected to the top of the second gear 514. Three third gears 515 are provided on the outer surface of the second gear 514, and the outer surface of the second gear 514 is meshed with the outer surfaces of the three third gears 515. A polygonal plate 516 is provided at the bottom of the second gear 514, and the top of the polygonal plate 516 is meshed with the bottom of the first rotating shaft 512 Fixed connection, by setting 512 at the bottom of the motor 511, the power generation of the motor 511 can be used to drive the rotation of the first rotating shaft 512. The bottom of the first rotating shaft 512 is fixedly connected to the polygonal plate 516, so when the first rotating shaft 512 rotates, the polygonal plate 516 will also rotate together. At this time, the three third gears 515 located at the top of the polygonal plate 516 will rotate on the outer surface of the second gear 514. At the same time, the three third gears 515 also drive the fourth gear 522 connected to the bottom to move. In addition to rotating the rotating device 51 as a whole above the inside of the mixing tank 3, the stirring blade 526 in the movable device 52 can also rotate to prevent the unevenness in the liquid components from having a negative impact on the quality of the process and thus affecting the performance of the final product. Therefore, it will not only rotate and stir in the middle, but also increase the strength to stir the slurry at the bottom in a small range. The raised part of the polygonal plate 516 is provided with a movable device 52, and the raised part of the polygonal plate 516 is movably connected to the top of the movable device 52.

[0034] The movable device 52 includes three second rotating shafts 521, and the bottom of the three second rotating shafts 521 is provided with a fourth gear 522, and the bottom of the three second rotating shafts 521 is fixedly connected to the center of the fourth gear 522, the outer surfaces of the three fourth gears 522 are provided with a fifth gear 523, and the outer surfaces of the three fourth gears 522 are meshed with the outer surfaces of the fifth gear 523, the center of the three fifth gears 523 is provided with a third rotating shaft 524, and the center of the three fifth gears 523 is fixedly connected to the bottom of the third rotating shaft 524, and the top of each second rotating shaft 521 and the third rotating shaft 524 is movably connected to the hollowed-out part of the raised part of the polygonal plate 516.

[0035] The bottom of the three third rotating shafts 524 is provided with an elliptical plate 525, and the bottom of the three third rotating shafts 524 is fixedly connected to one end of the elliptical plate 525, and the other end of the three elliptical plates 525 is provided with a stirring blade 526, and the other end of the three elliptical plates 525 is movably connected to the top of the stirring blade 526. By setting the second rotating shaft 521 to be connected with the third gear 515, the second rotating shaft 521 will be driven to twist after the third gear 515 rotates. The second rotating shaft 521 is fixedly connected to the fourth gear 522, so the fourth gear 522 will be connected to drive the outer fifth gear 523 to rotate together, thereby realizing the inner circumferential movement of the mixing tank 3. The stirring blades 526 connected to the bottom of the three elliptical plates 525 will also rotate with the power generation of the motor 511. The powder with large particle size will be deposited at the bottom of the mixing tank 3, while the powder with small particle size will float on it, thereby causing slurry stratification. At this time, in addition to the large rotation of the three stirring blades 526, the separated slurries can also be mixed and stirred together by self-rotation to improve the utilization rate of the slurry. The bottoms of the three stirring blades 526 are correspondingly connected to the top of the drain plate 4 .

[0036] The feeding device 6 includes a support plate 61, a long strip plate 62 is provided at the bottom of the support plate 61, and the bottom of the support plate 61 is fixedly connected to the top of the long strip plate 62, a double-axis cylinder 63 is provided at the center bottom of the support plate 61, and the center bottom of the support plate 61 is fixedly connected to the top of the double-axis cylinder 63, and connecting blocks 64 are provided at the output shafts at both ends of the double-axis cylinder 63. By arranging the double-axis cylinder 63 inside the support plate 61, the power of the double-axis cylinder 63 itself can be used to pull the connecting blocks 64 fixedly connected at the output shafts at both ends. Since the bottom of the connecting block 64 is fixedly connected to the fixed plate 67, in addition to pushing the fixed plate 67 to move to both sides, it will also drive the movement of the feeding pipe 68 connected to the bottom of the fixed plate 67, and move the slurry inside the two feeding pipes 68 to the bottom of the bottom stirring device 5 for stirring, which saves the need for manual secondary feeding and prevents the uniformity of the slurry from being affected, which will reduce the efficiency of the process and thus affect the overall efficiency of the production line. The output shafts at both ends of the dual-axis cylinder 63 are fixedly connected to the inner side of the connecting block 64 .

[0037] Both ends of the bottom of the long strip 62 are provided with sliding rods 65, and both ends of the bottom of the long strip 62 are fixedly connected to the top of the sliding rod 65, the outer surfaces of the two sliding rods 65 are provided with two sliding blocks 66, and the outer surfaces of the two sliding rods 65 are movably connected to the inside of the two sliding blocks 66, the bottoms of the two sliding blocks 66 are provided with fixed plates 67, and the bottoms of the two sliding blocks 66 are fixedly connected to the top of the fixed plates 67, and the middle of the two fixed plates 67 is fixedly connected to the top of the motor 511 in the rotating device 51, the tops of the two fixed plates 67 are fixedly connected to the bottoms of the two connecting blocks 64, and the bottoms of the two fixed plates 67 are hollowed out. The hollow spaces are all provided with feed pipes 68. By providing two sliding rods 65 at the bottom of the long strip 62, the sliding block 66 movably connected to the outer surface of the sliding rod 65 can help the fixed plate 67 at the bottom to slide back and forth. Under the pull of the two ends of the top double-axis cylinder 63, the feed pipes 68 at the hollow spaces of the two fixed plates 67 will be stretched to both sides first. After different slurries are put in, the double-axis cylinder 63 will extend and retract to drive the feed pipes 68 to move to the top of the mixing tank 3. Finally, the slurry inside the feed pipes 68 will slide to the bottom of the stirring device 5 for sufficient mixing and stirring. The good slurry uniformity can effectively improve the process efficiency and save energy consumption and production costs. The hollow spaces at the bottom of the two fixed plates 67 are fixedly connected to the outer surface of the feed pipes 68.

[0038] When in use, different slurries are first poured into the feeding pipe 68 in the feeding device 6, and then mixed and stirred by the stirring device 5 in the mixing tank 3, and finally filtered and filtered out through the leakage plate 4. The stirring device 5 includes a rotating device 51 and a movable device 52. The motor 511 in the rotating device 51 drives the first rotating shaft 512 connected to the bottom to rotate through electric power generation. The first rotating shaft 512 and the polygonal plate 516 are fixedly connected. Therefore, under the rotation of the first rotating shaft 512, the polygonal plate 516 will also rotate, thereby driving the three top parts of the polygonal plate 516 to rotate. The third gear 515 is meshed and movable on the outer surface of the second gear 514. The bottom of the third gear 515 is fixedly connected to a movable device 52. The second rotating shaft 521 in the movable device 52 is fixedly connected to the third gear 515, so that the second rotating shaft 521 can rotate with the fourth gear 522 and the fifth gear 523 at the bottom. The stirring blade 526 connected to the bottom of the elliptical plate 525 can not only rotate back and forth inside the mixing tank 3, but also rotate by itself when the stirring blade 256 is powered by the motor 511, so as to prevent uneven stirring of different slurries. The double-axis cylinder 63 in the feeding device 6 is fixedly connected to the connecting block 64 at both ends. When the double-axis cylinder 63 is continuously extended and retracted by its own power, it will drive the fixed plate 67 fixedly connected to the bottom of the connecting block 64 to slide on the outer surface of the sliding rod 65, which can prevent the slow speed caused by the excessive weight of the bottom device. The feeding pipe 68 is fixedly connected to the fixed plate 67, so the feeding pipe 68 will also move with the extension of the double-axis cylinder 63. First, different slurries are manually poured into the two feeding pipes 68, and then moved to the top of the stirring device 5 through the contraction of the double-axis cylinder 63. Then, the movable device 52 in the stirring device 5 first rotates one of the stirring blades 526 for simple stirring, and then continues to pour other slurries and turn on the three stirring blades 526 to rotate simultaneously, ensuring that the excellent slurry is fully stirred, thereby improving the quality of the product.
