[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0036] This invention provides a high-speed, high-throughput printing method and apparatus, such as... Figure 1-10As shown, the high-speed, high-throughput printing method and apparatus includes: a base 1, on which an adjustable placement plate 2 is provided; strong magnet blocks 3 symmetrically fixed on the placement plate 2 for adsorbing the construction plate 4; a gantry frame 5 fixed on the base 1, on which an adjustable discharge structure 6 is provided; a slot plate 37 assembled on the gantry frame 5, on which an adjustment frame 29 is provided, on which a protective shell 30 is fixed, and a rotating shaft 31 is assembled inside the protective shell 30 through a bearing for placing consumable rolls; a transverse movement mechanism disposed on the gantry frame 5 for adjusting the transverse movement of the discharge structure 6; and a lifting mechanism disposed on the gantry frame 5 for controlling the lifting of the transverse movement mechanism.
[0037] In this embodiment, the construction plate 4 is placed on the placement plate 2. The placement plate 2 can be adjusted back and forth via the base 1. The strong magnet 3 on the placement plate 2 will attract the construction plate 4, making it stable. The consumable roll is placed on the rotating shaft 31 inside the protective shell 30. The protective shell 30 is fixed on the adjusting frame 29, which is set on the slot plate 37, and can adjust the position of the consumable roll to a certain extent. The lifting mechanism controls the traverse mechanism to lift and lower on the gantry 5. At the same time, the traverse mechanism is used to adjust the traverse movement of the discharge structure 6 on the gantry 5, thereby controlling the discharge structure 6 to perform printing operations on the construction plate 4.
[0038] Through a specific structural design, the ejection structure 6 can operate stably during high-speed printing, avoiding insufficient heat supply at the hot end that prevents the filament from melting completely, thereby reducing the product defect rate. The placement plate 2 can be adjusted forward and backward. Combined with the adsorption of the construction plate 4 by the strong magnet block 3 and the lateral and vertical adjustment of the ejection structure 6, the printing process can be made more precise, ensuring the quality of the printed products. The rotating shaft 31 inside the protective shell 30 is used to place the filament roll, and the related adjustment structure facilitates the adjustment of the position of the filament roll, improving the convenience and stability of filament supply during the printing process.
[0039] In a further preferred embodiment of the present invention, the discharge structure 6 includes: a mounting box 7 disposed on one side of the gantry frame 5; an assembly shell 8 fixed to the bottom of the mounting box 7; a rotating rod 9 mounted in the assembly shell 8 via bearings, the rotating rod 9 having a conical block 10 fixed on it for guiding the consumable filament; a heating block 11 disposed below the assembly shell 8 for heating the consumable filament, the heating block 11 having a thermal break 12 disposed between it and the assembly shell 8; a nozzle 13 on the discharge end of the heating block 11; a transmission rod 14 mounted in the mounting box 7 via bearings, the transmission rod 14 having a first bevel tooth 15 fixed on it and the rotating rod 9 for meshing; and a first stepper motor 16 mounted on the mounting box 7, the output shaft of the first stepper motor 16 being fixedly connected to the transmission rod 14 via a coupling.
[0040] In this embodiment, the first stepper motor 16 is started, and the output shaft of the motor drives the transmission rod 14, which is connected to it by a coupling, to rotate. The rotation of the transmission rod 14, through the first bevel tooth 15 meshing with the rotating rod 9, drives the rotating rod 9 to rotate within the assembly housing 8, so that the cone block 10 on the rotating rod 9 rotates synchronously. When the cone block 10 rotates, its surface texture presses out grooves on the filament wire and guides the filament wire to move downward.
[0041] When the filament reaches the heating block 11, the thermostat on the heating block 11 starts working, raising the temperature of the heating block 11 to the set temperature to heat the filament. During this process, the thermocouple continuously measures the temperature of the heating block 11 and feeds it back to the thermostat. The thermostat dynamically adjusts the heating power based on the thermocouple feedback to maintain a constant temperature of the heating block 11.
[0042] Meanwhile, the thermal circuit breaker 12 plays a crucial protective role by monitoring the temperature during the heating process in real time. Once it detects an abnormal increase in the temperature of the heating block 11, it will activate to keep it under constant temperature conditions. On the other hand, the thermal circuit breaker 12 is also located between the heating block 11 and the cone block 10. By blocking the transfer of heat from the heating block 11 to the cone block 10, it prevents the consumable wire from softening and deforming before reaching the heating block 11 due to high temperature conduction, thus affecting the feeding accuracy.
[0043] The conical block 10 presses out grooves to increase the heating area of the filament, and combined with the precise constant temperature heating of the heating block 11, ensures that the filament melts quickly and fully, effectively solving the problem of insufficient filament melting during high-speed printing and reducing product defect rate. The first stepper motor 16, in conjunction with the transmission structure, precisely controls the filament feed speed. Thermocouples and thermostats work together to achieve precise control of heating temperature, ensuring stability in the printing process. The thermal circuit breaker 12 serves as a safety barrier to prevent heating runaway and ensure the safety of the equipment and printing operation. The constant temperature control of the heating block 11 avoids uneven filament melting caused by temperature fluctuations, providing stable material supply conditions for printing operations, which is conducive to improving printing accuracy and product quality consistency.
[0044] In a further preferred embodiment of the present invention, the transverse movement mechanism includes: an adjustment box 24 disposed on the gantry frame 5, wherein a first screw 25 is assembled in the adjustment box 24 via bearings; an adjustment block 26 threaded onto the first screw 25, the bottom end of the adjustment block 26 being fixedly connected to the mounting box 7; a second stepper motor 28 fixed on the adjustment box 24, the output shaft of the second stepper motor 28 being fixedly connected to the first screw 25 via a coupling; and a first guide rod 27 fixed in the adjustment box 24, the first guide rod 27 passing through the adjustment block 26.
[0045] In this embodiment, the second stepper motor 28 is activated, and its output shaft drives the first screw 25 to rotate within the adjusting box 24 via a coupling. Since the adjusting block 26 is threaded onto the first screw 25, it moves axially along the first screw 25 as the first screw 25 rotates. The bottom end of the adjusting block 26 is fixedly connected to the mounting box 7, so the movement of the adjusting block 26 causes the mounting box 7 to move synchronously. The mounting box 7 is part of the discharge structure 6, thus enabling the discharge structure 6 to move laterally on the gantry frame 5.
[0046] During the movement of the adjusting block 26, the first guide rod 27 passes through the adjusting block 26, providing guidance for the movement of the adjusting block 26 and ensuring that the adjusting block 26 moves smoothly along the axial direction of the first screw 25, avoiding deviation or shaking during the movement.
[0047] The rotation angle and speed of the first screw 25 are precisely controlled by the second stepper motor 28, thereby accurately regulating the lateral movement position and speed of the adjusting block 26 and the connected discharge structure 6. This precise control enables the nozzle 13 to accurately print at different positions on the construction plate 4, meeting the printing needs of complex patterns and structures and improving printing accuracy. The guiding effect of the first guide rod 27 on the adjusting block 26 ensures the stability of the discharge structure 6 during lateral movement. Stable lateral movement avoids problems such as uneven line thickness and positional deviation caused by nozzle wobbling, making the printing process more stable and improving the quality and consistency of printed products.
[0048] In a further preferred embodiment of the present invention, the lifting mechanism includes: a third screw 38 mounted on the gantry frame 5 via bearings; a connecting block 40 threaded onto the third screw 38, one end of the connecting block 40 being fixedly connected to the adjusting box 24; and a third stepper motor 39 fixed on the gantry frame 5, the output shaft of the third stepper motor 39 being fixedly connected to the third screw 38 via a coupling.
[0049] In this embodiment, when the third stepper motor 39 is started, its output shaft drives the third screw 38 to rotate on the gantry 5 via a coupling. Since the connecting block 40 is threaded onto the third screw 38, as the third screw 38 rotates, the connecting block 40 moves up and down along the axial direction of the third screw 38. One end of the connecting block 40 is fixedly connected to the adjusting box 24, and the up-and-down movement of the connecting block 40 drives the adjusting box 24 to rise and fall synchronously. The adjusting box 24 is part of the transverse movement mechanism, which allows the entire transverse movement mechanism and the connected discharge structure 6 to rise and fall on the gantry 5. By controlling the forward and reverse rotation and the number of rotations of the third stepper motor 39, the rotation direction and angle of the third screw 38 are precisely controlled, thereby achieving precise adjustment of the lifting and lowering positions of the connecting block 40, the adjusting box 24, and the discharge structure 6.
[0050] The third stepper motor 39 can precisely control the rotation of the third screw 38, thereby accurately adjusting the lifting height of the connecting block 40, and ultimately achieving precise adjustment of the height of the discharge structure 6. This ensures that each layer of material is accurately laid out, greatly improving printing accuracy and reducing product defects caused by height deviations, especially in scenarios requiring precise control of printing height, such as multi-layer printing and printing of materials of different thicknesses.
[0051] In a further preferred embodiment of the present invention, an electric guide rail 41 is symmetrically fixed on the base 1, and the output block of the electric guide rail 41 is fixedly connected to the bottom of the placement plate 2.
[0052] In this embodiment, the symmetrically arranged electric guide rails 41 on the start base 1 are activated. Once powered on, the electric guide rails 41 begin operation, and their internal drive mechanism operates. The output block of the electric guide rails 41 moves linearly along the predetermined direction of the guide rail under the action of the drive mechanism. Since the output block is fixedly connected to the bottom of the placement plate 2, the movement of the output block causes the placement plate 2 to move synchronously. By controlling the energizing duration, current magnitude, or specific control commands of the electric guide rails 41, the moving distance and speed of the output block can be precisely adjusted, thereby achieving precise control of the position of the placement plate 2. The electric guide rails 41 can precisely control the moving distance and speed of the placement plate 2, making the position adjustment of the build plate 4 during the printing process more accurate. This greatly improves printing accuracy and ensures the accuracy of the printed patterns and models, especially in situations where the printing start position needs to be precisely placed on the build plate 4, or where the build plate 4 needs to be precisely moved during the printing process to match the printing path of the output structure 6.
[0053] In a further preferred embodiment of the present invention, a telescopic guide tube 23 for guiding consumable filaments is fixedly installed on the adjustment frame 29, and the filament outlet end of the telescopic guide tube 23 is connected to the mounting box 7.
[0054] In this embodiment, after the filament filament is released from the filament roll placed on the rotating shaft 31 inside the protective shell 30, it first enters the telescopic guide tube 23 fixedly installed on the adjusting frame 29. The telescopic guide tube 23 maintains smooth filament feeding by extending and retracting according to the position change of the discharge structure 6 on the gantry 5. When the discharge structure 6 is adjusted horizontally or vertically, the telescopic guide tube 23 extends or retracts accordingly to ensure that the filament filament is stably fed from its filament outlet to the position connected to the mounting box 7. After the filament filament enters the mounting box 7 through the filament outlet of the telescopic guide tube 23, it continues along the path of the discharge structure 6, guided by the cone block 10 on the rotating rod 9, heated by the heating block 11, and finally extruded from the nozzle 13 for printing.
[0055] The telescopic guide tube 23 can adaptively extend and retract as the position of the discharge structure 6 changes, effectively avoiding problems such as tangling and jamming of the filament filament during the conveying process due to changes in the position of the discharge structure 6. This ensures a continuous and stable supply of filament filament to the discharge structure 6, which is crucial for maintaining the continuity and stability of the printing process and reduces printing interruptions and product defects caused by poor filament delivery.
[0056] In a further preferred embodiment of the present invention, a first bracket 17 and a second bracket 21 are symmetrically arranged inside the mounting box 7. The first bracket 17 is fixedly connected to the mounting box 7. Guide wheels 22 are rotatably mounted on both the first bracket 17 and the second bracket 21 for guiding consumable filaments. An mounting cylinder 18 is fixed on the inner wall of the mounting box 7. A damping block 19 and a spring are arranged inside the mounting cylinder 18. A sliding rod 20 is fixed on the spring. One end of the sliding rod 20 is fixedly connected to the second bracket 21.
[0057] In this embodiment, after the filament enters the mounting box 7, it first contacts the guide wheels 22 rotatably mounted on the first bracket 17 and the second bracket 21. During the conveying process, the filament moves along the circumferential surface of the guide wheel 22, which rotates accordingly, guiding the filament's direction. The second bracket 21 is connected to the damping block 19 and spring inside the mounting cylinder 18 via a slide rod 20. When the tension of the filament changes during conveying, such as when the movement of the discharge structure 6 causes a change in the filament's conveying speed, the second bracket 21 will move under force. At this time, the slide rod 20 slides inside the mounting cylinder 18, compressing or stretching the spring, while the damping block 19 dampens the movement of the slide rod 20, slowing down the movement speed of the second bracket 21 and preventing it from rapidly displacing due to sudden changes in force.
[0058] Throughout the process, the first bracket 17 remains fixed, providing stable support for the guide wheel 22, while the second bracket 21, through the synergistic action with the spring and damping block 19, can adaptively adjust its position according to the changes in the tension of the consumable filament, ensuring that the two guide wheels 22 can always stably guide the consumable filament.
[0059] The guide roller 22 can accurately guide the filament filament within the mounting box 7, preventing it from becoming tangled or shifting in the complex internal environment of the mounting box 7. This ensures that the filament filament can be stably and accurately delivered to subsequent components such as the heating block 11, laying the foundation for the stability of the printing process and reducing printing failures caused by chaotic filament filament delivery paths.
[0060] The structure consisting of a spring and a damping block 19 allows the second support 21 to adaptively adjust its position according to changes in filament tension. When the filament tension is too high, the spring is compressed, and the second support 21 moves to relieve the tension; when the tension is too low, the spring rebounds, and the second support 21 returns to its original position. This adaptive adjustment maintains constant filament tension during the feeding process, preventing problems such as filament jamming and uneven feeding caused by unstable tension, thus improving printing quality and ensuring higher precision and more stable product quality.
[0061] In a further preferred embodiment of the present invention, a second screw 32 is assembled in the groove plate 37 via a bearing, and the second screw 32 is threaded through the adjusting frame 29.
[0062] In this embodiment, when the position of the adjusting frame 29 needs to be adjusted, the second screw 32, which is mounted in the rotating slot plate 37 via a bearing, is rotated. Since the second screw 32 is threaded through the adjusting frame 29, according to the principle of threaded transmission, as the second screw 32 rotates, the adjusting frame 29 will move along the axial direction of the second screw 32. To move the adjusting frame 29 in a specific direction, the clockwise or counterclockwise rotation of the second screw 32 can be controlled. For example, rotating the second screw 32 clockwise will move the adjusting frame 29 in one direction; rotating it counterclockwise will move it in the opposite direction.
[0063] By continuously rotating the second screw 32, the movement distance of the adjustment frame 29 can be precisely controlled until it is adjusted to the desired position, thus completing the setting of the position of the adjustment frame 29. Rotating the second screw 32 allows for precise adjustment of the position of the adjustment frame 29, on which a protective shell 30 for holding the filament roll is fixed. Therefore, this structure can precisely control the position of the filament roll, ensuring the accuracy of the filament filament's position during the initial feeding stage. This facilitates the stable and smooth feeding of the filament filament to the output structure 6, improving the stability of filament supply during printing and thus enhancing print quality. The adjustable position of the adjustment frame 29 allows the equipment to adapt to filament rolls of different sizes and shapes, as well as the specific requirements of different printing models for the initial filament position. Whether using filament rolls with larger or smaller diameters, or when fine-tuning the filament position is required when printing complex models, the second screw 32 allows for flexible adjustment of the adjustment frame 29, enhancing the printing equipment's adaptability to diverse printing tasks.
[0064] In a further preferred embodiment of the present invention, the base 1 is provided with symmetrical through slots, which are adapted to the output block of the electric guide rail 41.
[0065] In this embodiment, when installing the output block of the electric guide rail 41, the output block is aligned with the symmetrical through slots on the base 1. Since the through slots are compatible with the output block, when the electric guide rail 41 is working, the output block moves linearly along the direction of the through slot, driving the placement plate 2 fixedly connected to it to move synchronously, thus completing the adjustment operation of the position of the placement plate 2.
[0066] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:
[0067] In another embodiment of the present invention, a linkage mechanism is provided on the gantry frame 5, the first screw 25, and the adjusting box 24 for driving the second screw 32 to rotate. The linkage mechanism includes: a spline rod 33 vertically mounted on one side of the gantry frame 5 via a bearing seat; a spline sleeve 34 sleeved on the spline rod 33; a bearing seat provided on the spline sleeve 34; the bearing seat being fixedly connected to the adjusting box 24; two second bevel teeth 35 respectively fixed on the spline rod 33 and the first screw 25, the two second bevel teeth 35 meshing for transmission; and third bevel teeth 36 respectively fixed on the spline rod 33 and the second screw 32, the two third bevel teeth 36 meshing for transmission.
[0068] In this embodiment, when the second stepper motor 28 starts and drives the first screw 25 to rotate within the adjusting box 24, the rotation of the first screw 25 is transmitted to the spline rod 33 through these two meshing second bevel teeth 35, since the first screw 25 is fixed with a second bevel tooth 35 and this second bevel tooth 35 meshes with the second bevel tooth 35 on the spline rod 33. This causes the spline rod 33 to begin rotating. When the spline rod 33 rotates, the spline sleeve 34 fitted on it also rotates. Simultaneously, the bearing seat on the spline sleeve 34 is fixedly connected to the adjusting box 24, ensuring stable rotation of the spline sleeve 34. The rotation of the spline rod 33 then transmits power to the second screw 32 through the third bevel tooth 36 meshing with it, causing the second screw 32 to rotate within the slot plate 37. As the second screw 32 rotates, the adjusting bracket 29 threaded through it moves along the axial direction of the second screw 32, thereby adjusting the position of the adjusting bracket 29.
[0069] The linkage mechanism enables the rotation of the first screw 25 to drive the rotation of the second screw 32, linking the action of the transverse movement mechanism with the adjustment of the position of the adjusting frame 29. This means that while adjusting the transverse position of the discharge structure 6, the position of the consumable roll placed on the adjusting frame 29 can be adjusted simultaneously, making the operation between the various components of the equipment more coordinated and improving the continuity and automation of the printing process. Through the linkage mechanism, the power of the transverse movement mechanism is used to drive the adjustment of the position of the adjusting frame 29, eliminating the need for an additional independent drive device to control the adjusting frame 29.
[0070] This invention proposes a printing method for a high-speed, high-throughput printing device, comprising the following steps:
[0071] Step S1: Place the construction board on the placement plate 2 of the base 1, fix it with strong magnets 3, and adjust the front and back position of the placement plate 2 by electric guide rail 41.
[0072] Step S2: Install the consumable roll on the rotating shaft 31 inside the protective shell 30, limit it with a nut, and introduce the consumable wire into the installation box 7 through the telescopic guide tube 23;
[0073] Step S3: Start the third stepper motor 39 and adjust the height of the discharge structure 6 through the third screw 38 and connecting block 40; start the second stepper motor 28 and adjust the lateral position of the discharge structure 6 through the first screw 25, adjusting block 26 and first guide rod 27.
[0074] Step S4: Turn on the first stepper motor 16, which drives the transmission rod 14, and through the first bevel gear 15, causes the rotating rod 9 and the cone block 10 to rotate, guiding the consumable wire forward; the consumable wire is guided by the guide wheel 22 on the first bracket 17 and the second bracket 21 in the mounting box 7, and the spring and damping block 19 in the mounting cylinder 18 stably feed the wire.
[0075] Step S5: The filament enters the heating block 11 to melt, is protected by the thermal breaker 12, and is extruded by the nozzle 13. The discharge structure 6 moves horizontally and rises and falls according to the preset path, and is adjusted back and forth with the placement plate 2 to print layer by layer on the construction plate 4.
[0076] Step S6: Power off heating block 11 stops working;
[0077] Step S7: After the product has cooled down, remove the build plate 4 to obtain the printed product, clean the equipment of any remaining consumables, and put all components back in their original positions.
[0078] In summary, compared with related technologies, the adjustable placement plate 2 on the base 1, combined with the strong magnet block 3 to stabilize the building plate 4, the flexible transverse movement mechanism on the gantry 5 including the adjustment box 24, the first screw 25, and the lifting mechanism including the third screw 38, precisely controls the position of the discharge structure 6; the cone block 10 inside the discharge structure 6, combined with the heating block 11 including the thermostat, thermocouple, and thermal circuit breaker 12, efficiently melts the filament; the telescopic guide tube 23 and guide wheel 22 ensure stable delivery of the filament; and the second screw 32 precisely adjusts the position of the adjustment frame 29, achieving high-speed, high-throughput printing, reducing product defect rate, improving printing accuracy and stability, and enhancing the equipment's adaptability to diverse printing tasks.
