[0014] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, the components and methods of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0015] Existing printers only have one printhead. When it is necessary to change the material for printing, it is often necessary to unload the old material from the printhead and then load the new material. This material changing method is not only time-consuming, but also wastes materials.

[0016] To address the aforementioned issues, embodiments of this application provide a printer. Figure 1 This is a schematic diagram showing the printer assembled according to an embodiment of this application.

[0017] like Figure 1 As shown, the printer 100 provided in the embodiments of this application includes: a support moving component 10, a carrier 20, and a printing assembly 30. The support moving component 10 is configured to drive the printing assembly 30 and the carrier 20 to move relative to each other on the support moving component 10, so that the printing assembly 30 can extrude material to different positions on the carrier 20. The printing assembly 30 is configured to have a plurality of printheads 312, and the plurality of printheads 312 are configured to be switchable to extrude different materials to the carrier 20.

[0018] The printer 100 provided in the embodiments of this application has multiple switchable printheads 312, which can quickly switch the printheads 312 according to printing needs to extrude different materials to the carrier 20, greatly improving the efficiency of material changing and avoiding material waste.

[0019] In some embodiments, printer 100 may be a 3D printer.

[0020] Figure 2 This is a schematic diagram of the unassembled printing assembly 30 according to an embodiment of this application, see also Figure 2In some embodiments, the printing assembly 30 includes: a printing assembly 31 configured to have a plurality of printheads 312 and configured to switch between the plurality of printheads 312 to extrude different materials to the carrier 20; a cooling assembly 32 disposed on the printing assembly 31 and configured to cool the printheads 312 and the materials extruded by the printheads 312; a leveling member 33 disposed on the cooling assembly 32 and configured to determine the distance between the printheads 312 and any position on the carrier 20, and control the printheads 312 to move closer to or further away from the carrier 20 according to the distance; and the leveling member 33 is disposed on a support moving assembly 10, the support moving assembly 10 being configured to drive the leveling member 33, the cooling assembly 32 and the printing assembly 31 to move on the support moving assembly 10.

[0021] In this embodiment, the leveling component 33 can detect the distance between the print head 312 and any position on the carrier 20. Therefore, during the printing of the first layer, the leveling component 33 can control the print head 312 to move closer to or further away from the carrier 20 based on the detected distance, ensuring that the distance between the print head 312 and the carrier 20 remains at an appropriate level. This allows the material extruded from the print head 312 to be accurately coated onto the carrier 20, ensuring the successful completion of the first layer printing. The cooling component 32 can cool the material extruded from the print head 312, allowing the extruded material to quickly solidify. It also helps dissipate heat from the print head 312, enabling it to operate continuously.

[0022] In some embodiments, the printing assembly 31 includes: a mounting rotation assembly 311 disposed on the cooling assembly 32; a plurality of printheads 312 mounted on the mounting rotation assembly 311; a material conveying member 313 connected to the plurality of printheads 312 to convey different materials to each printhead 312; and a driving member 314 configured to drive the mounting rotation assembly 311 to rotate by a predetermined angle, thereby driving the plurality of printheads 312 to rotate by a predetermined angle, thereby enabling the switching of different printheads 312 to working positions to extrude different materials onto the carrier 20.

[0023] In this embodiment, the method of using the drive component 314 to drive the rotating mounting assembly 311 to rotate has high rotational accuracy. This drives the multiple printheads 312 mounted on the rotating mounting assembly 311 to rotate by a predetermined angle, enabling the printheads 312 loaded with the desired material to accurately rotate to the working position for printing. Furthermore, the process of switching printheads 312 is simple and convenient, greatly improving the efficiency of material replacement and avoiding material waste.

[0024] In some embodiments, the mounting of the rotating assembly 311 includes: a rotating assembly 3111; a fixing member 3112 disposed on the cooling assembly 32; a support member 3113 configured to mount the rotating assembly 3111 on the fixing member 3112 and enable the rotating assembly 3111 to rotate relative to the fixing member 3112; and a printhead mounting member 3114 disposed on the rotating assembly 3111 and configured to mount a plurality of printheads 312; wherein the driving member 314 is configured to drive the rotating assembly 3111 to rotate relative to the fixing member 3112 by a predetermined angle, thereby driving the plurality of printheads 312 to rotate by a predetermined angle, thereby enabling the switching of different printheads 312 to working positions to extrude different materials to the carrier 20.

[0025] In such an embodiment, the support member 3113 places the rotating component 3111 on the fixing member 3112, and enables the rotating component 3111 to rotate relative to the fixing member 3112. The driving member 314 drives the rotating component 3111, enabling the rotating component 3111 to rotate relative to the fixing member 3112, thereby driving multiple printheads 312 to also rotate relative to the fixing member 3112.

[0026] In some embodiments, the rotating assembly 3111 includes: a first rotating member 31111, a support member 3113 configured to mount the first rotating member 31111 on a fixing member 3112 and enable the first rotating member 31111 to rotate relative to the fixing member 3112, a printhead mounting member 3114 connected to the first rotating member 31111; a second rotating member 31112 cooperating with the first rotating member 31111; and a driving member 314 configured to drive the second rotating member 31112 to rotate, thereby causing the first rotating member 31111 to rotate relative to the fixing member 3112.

[0027] In such an embodiment, by setting the first rotating member 31111 to cooperate with the second rotating member 31112, the driving member 314 drives the second rotating member 31112 to rotate, which in turn drives the first rotating member 31111 to rotate.

[0028] In some embodiments, the first rotating member 31111 and the second rotating member 31112 are configured to be threadedly engaged.

[0029] In some embodiments, the drive element 314 may be a motor.

[0030] In some embodiments, the support member 3113 is sleeved on the first rotating member 31111, the fixing member 3112 is sleeved on the support member 3113, and the first rotating member 31111 is rotatable relative to the fixing member 3112.

[0031] In this embodiment, the support member 3113 is disposed between the first rotating member 31111 and the fixed member 3112, providing support for the first rotating member 31111. This allows the first rotating member 31111 to rotate stably within the fixed member 3112 relative to the fixed member 3112 when driven to rotate by the driving member 314, without radial or axial displacement, thus ensuring the stability of the rotational motion. Furthermore, the first rotating member 31111 and the fixed member 3112 are coaxially arranged, integrating a rotating structure, which allows space to be provided for the material conveying member 313 and the driving member 314 near the installation location of the rotating assembly 311.

[0032] In some embodiments, the support member 3113 is a bearing, the fixing member 3112 is fixedly connected to the outer ring of the bearing, and the first rotating member 31111 is fixedly connected to the inner ring of the bearing. In such an embodiment, the support member 3113 can reduce the friction between the first rotating member 31111 and the fixing member 3112, extend the service life of the first rotating member 31111 and the fixing member 3112, and also improve the rotation accuracy, so that the print head 312 loaded with the expected material can be accurately rotated to the working position.

[0033] In some embodiments, the first rotating member 31111 includes: a rotating part 311111, a connecting part 311112, and a mating part 311113, wherein the rotating part 311111, the connecting part 311112, and the mating part 311113 are integrally formed; the connecting part 311112 is disposed between the rotating part 311111 and the mating part 311113, respectively connecting the rotating part 311111 and the mating part 311113, wherein the radial dimensions of the rotating part 311111 and the mating part 311113 are larger than those of the connecting part 311112; the support member 3113 is sleeved on the connecting part 311112; the printhead mounting member 3114 is connected to the mating part 311113; and the second rotating member 31112 mates with the rotating part 311111.

[0034] In this embodiment, the radial dimension of the connecting portion 311112 between the rotating portion 311111 and the mating portion 311113 is smaller than that of the rotating portion 311111 and the mating portion 311113. The support member 3113 is sleeved outside the connecting portion 311112, which helps to reduce the size of the support member 3113, thereby reducing the size of the rotating assembly 311 and preventing the rotating assembly 311 from being too heavy or too large, thus saving space.

[0035] Figure 3 This is a schematic diagram showing the assembled printing assembly 30 according to an embodiment of this application. See also... Figure 3 In some embodiments, the printhead 312 is configured to be perpendicular to the carrier 20 when it is in the working position.

[0036] See also Figure 3 In some embodiments, the cooling assembly 32 is disposed perpendicular to the carrier 20, and the fixing member 3112 and the rotating assembly 3111 are disposed at an angle away from the carrier 20 relative to the cooling assembly 32; the printhead mounting member 3114 is configured as a cone, and a plurality of printheads 312 are mounted on the side surface of the cone, such that the printheads 312 in the working position are perpendicular to the carrier 20.

[0037] In this embodiment, the cooling assembly 32 is perpendicular to the support member 20, and the fixing member 3112 is disposed on the cooling assembly 32. The fixing member 3112 and the rotating assembly 3111 are inclined away from the support member 20 relative to the cooling assembly 32, so that there is sufficient space between the printhead mounting member 3114 mounted on the rotating assembly 3111 and the cooling assembly 32 for mounting the printhead 312. Furthermore, the printhead mounting member 3114 is configured as a cone, and multiple printheads 312 are disposed on the side surface of the cone, such that the multiple printheads 312 are angled to the axis of the rotating assembly 3111. The inclination of the side surface of the cone can compensate for the inclination of the rotating assembly 3111, so that the printheads 312 rotated to the working position can be perpendicular to the support member 20, which is beneficial for printing. Meanwhile, the nozzles of the printheads 312 in other positions are at a certain distance from the carrier 20 and the printed structure, so they will not interfere with printing. This allows multiple printheads 312 to switch freely without affecting the printhead 312 that is printing or the printed structure.

[0038] In some embodiments, the carrier 20 is arranged horizontally, the cooling assembly 32 is arranged vertically, and the printhead 312 in the working position is arranged vertically.

[0039] In some embodiments, the printhead mount 3114 forms a plurality of mounting portions 31141, and a plurality of printheads 312 are correspondingly mounted on the plurality of mounting portions 31141. In such embodiments, the plurality of mounting portions 31141 of the printhead mount 3114 are adapted to the plurality of printheads 312, and the plurality of printheads 312 can be correspondingly mounted on the plurality of mounting portions 31141.

[0040] In some embodiments, the central angles corresponding to the lines connecting two adjacent mounting portions 31141 are equal. In such embodiments, setting the central angles corresponding to the lines connecting two adjacent mounting portions 31141 to be equal allows the printheads 312 to be evenly distributed on the printhead mounting member 3114. Each time the first rotating member 31111 rotates by the same angle, the next printhead 312 can rotate to the working position, reducing the complexity of controlling the rotation angle of the printhead 312.

[0041] Figure 4 This is a top view of the printing assembly 30 according to an embodiment of this application, see also Figure 4 In some embodiments, the material conveyor 313 and the plurality of printheads 312 are located on both sides of the printhead mount 3114. The material conveyor 313 is connected to the portion of the plurality of printheads 312 mounted on the plurality of mounting portions 31141, and the material conveyor 313 is configured to abut against the printhead mount 3114.

[0042] In this embodiment, the material conveyor 313 is connected to multiple printheads 312 and abuts against the printhead mounting member 3114. The printhead mounting member 3114 can provide support for the material conveyor 313, making the connection between the material conveyor 313 and the multiple printheads 312 tighter and more stable, and preventing the conveyed material from protruding from the joint between the material conveyor 313 and the printheads 312.

[0043] See Figure 2 and Figure 4 In some embodiments, the material conveying component 313 includes: a plurality of parallel conveying sections 3131, which are interconnected and parallel to each other; a plurality of extended conveying sections 3132, which are correspondingly connected to the plurality of parallel conveying sections 3131 and are at a certain angle to their correspondingly connected parallel conveying sections 3131; a plurality of supporting sections 3133, which are respectively connected to the plurality of extended conveying sections 3132 and are connected to the same position; the plurality of extended conveying sections 3132 are correspondingly connected to the portions of the plurality of printheads 312 mounted on the plurality of mounting portions 31141, and different materials are respectively conveyed to the plurality of parallel conveying sections 3131 and conveyed to different printheads 312 through the plurality of extended conveying sections 3132; and the plurality of supporting sections 3133 abut against the printhead mounting portion 3114.

[0044] In this embodiment, multiple support portions 3133 are respectively connected to multiple extended conveying portions 3132, and the multiple support portions 3133 are connected at the same position, which makes the structure of the material conveying component 313 more stable. When rotating together with the first rotating component 31111, the material conveying component 313's ability to withstand external loads is improved. The multiple support portions 3133 abut against the printhead mounting component 3114, which can provide support for the material conveying component 313, making the connection between the material conveying component 313 and the printhead 312 tighter and more stable.

[0045] In some embodiments, the cooling assembly 32 includes: a mounting member 321 connected to a fixing member 3112 of the printing assembly 31; a material cooling assembly 322 disposed on the mounting member 321 and configured to cool the material extruded by the print head 312; a print head cooling member 323 disposed on the mounting member 321 and configured to cool the print head 312; and a leveling member 33 disposed on the mounting member 321.

[0046] In this embodiment, both the material cooling assembly 322 and the printhead cooling component 323 are disposed on the mounting component 321, so that the material cooling assembly 322 and the printhead cooling component 323 are integrated on the mounting component 321, making the structure of the printing assembly 30 more compact.

[0047] In some embodiments, the material cooling assembly 322 includes a material cooling element 3221 and a guide element 3222, which are disposed on the mounting member 321. The material cooling element 3221 is disposed at the end of the mounting member 321 away from the printhead 312, and the printhead cooling element 323 is disposed at the end of the mounting member 321 close to the printhead 312. The material cooling element 3221 is configured to generate a cooling medium, and the guide element 3222 is configured to communicate with the material cooling element 3221 and extend toward the nozzle of the printhead 312 to guide the cooling medium generated by the material cooling element 3221 to the vicinity of the nozzle of the printhead 312 to cool the material extruded from the nozzle of the printhead 312.

[0048] In this embodiment, the printhead cooling element 323 is positioned at the end of the mounting member 321 near the printhead 312, allowing it to directly cool the printhead 312. The material cooling element 3221 is positioned at the end of the mounting member 321 away from the printhead 312. The guide element 3222 guides the cooling medium generated by the material cooling element 3221 to the vicinity of the nozzle of the printhead 312, ensuring that the cooling medium passes evenly over the freshly extruded material and the printed structure, achieving rapid and uniform cooling of both. Furthermore, this reasonable positioning of the material cooling element 3221 and the printhead cooling element 323 allows them to cool the extruded material and the printhead 312 respectively, without any conflict between their positions.

[0049] In some embodiments, the guide 3222 includes a connecting portion 32221, an outlet portion 32222, and two extension portions 32223, wherein the connecting portion 32221, the outlet portion 32222, and the extension portions 32223 are integrally formed; one end of each of the two extension portions 32223 is connected to both ends of the connecting portion 32221 and extends toward the nozzle of the print head 312, and the other end of each of the two extension portions 32223 is connected to both ends of the outlet portion 32222; the connecting portion 32221... The material cooling component 3221 is connected to the material cooling component 3221. The cooling medium generated by the material cooling component 3221 enters from the connecting part 32221 and exits from the outlet part 32222 to cool the material extruded from the nozzle of the print head 312. A channel is formed between the connecting part 32221, the outlet part 32222 and the two extension parts 32223. The print head cooling component 323 and the print head 312 are disposed on both sides of the channel. The cooling medium generated by the print head cooling component 323 can pass through the channel to cool the print head 312.

[0050] In this embodiment, since the material cooling component 3221 is located at the end of the mounting component 321 away from the printhead 312, and the printhead cooling component 323 is located at the end of the mounting component 321 close to the printhead 312, the guide component 3222 communicates with the material cooling component 3221 and extends towards the nozzle portion of the printhead 312, thus blocking the space between the printhead cooling component 323 and the printhead 312. Therefore, by forming a channel between the connecting portion 32221, the outlet portion 32222, and the two extension portions 32223 of the guide component 3222, the cooling medium generated by the printhead cooling component 323 can cool the printhead 312 through the channel. This achieves a reasonable design of the material cooling component 3221, the guide component 3222, and the printhead cooling component 323, allowing the material cooling component 322 for cooling the extruded material and the printhead cooling component 323 for cooling the printhead 312 to perform their respective functions without interfering with each other.

[0051] In some embodiments, the length of the outlet portion 32222 can be set as needed.

[0053] In such an embodiment, by setting the first moving member 12 to drive the printing assembly 30 to move along the first direction, the second moving member 13 to drive the carrier 20 to move along the second direction, and the third moving member 14 to drive the first moving member 12 to move along the third direction, the print head 312 and the carrier 20 are moved relative to each other along the first, second and third directions.

[0054] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other.

[0055] In some embodiments, the printer 100 further includes a first connector 40 configured to connect the leveling member 33 and the first moving member 12.

[0056] In some embodiments, the printing assembly 30 further includes a second connector 34, which is connected to the leveling member 33 and the mounting member 321 respectively, and the material cooling member 3221 and the printhead cooling member 323 are disposed between the second connector 34 and the mounting member 321.
