Description

Technical Field

[0001] This invention belongs to the field of 3D printing technology, specifically relating to a multi-nozzle 3D printer with a self-cleaning idle nozzle. Background Technology

[0002] A multi-nozzle 3D printer is a device equipped with two or more independent extrusion nozzles on a single 3D printer. Each nozzle can be loaded with filaments of different colors and materials, thus enabling more complex functions in a single printing job.

[0003] When cleaning a freshly used printhead in an existing multi-nozzle 3D printer, due to the different coefficients of thermal expansion, the printhead must be unscrewed while it is still hot to avoid damaging the screws. However, since the printhead is at a high temperature, improper unscrewing may burn the operator. Therefore, unscrewing the printhead is inconvenient, increases the difficulty of disassembling the printhead, and poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a multi-nozzle 3D printer with a self-cleaning, unused nozzle. When disassembling the nozzle, the nozzle can be clamped by clamping plates on both sides of the nozzle, and then the nozzle can be twisted to remove it. This makes it easier to remove the nozzle, reduces the difficulty of nozzle removal, reduces the safety hazards of nozzle removal, and makes it easier to clean the nozzle.

[0005] The specific technical solution adopted in this utility model is as follows: A multi-nozzle 3D printer with a self-cleaning idle nozzle includes a body compartment. A motion module is located at the top of the body compartment, and an internally threaded connecting sleeve is located at the bottom of the motion module. A nozzle is internally threaded into the internally threaded connecting sleeve, and the bottom of the nozzle extends to the outside of the internally threaded connecting sleeve. A compartment door is located on the front of the body compartment. A rotating component is located on the outer wall of the motion module. An elastic component is located at the end of the rotating component away from the motion module. A clamping plate is fixedly connected to the end of the elastic component near the nozzle, and the clamping plate extends to both sides of the nozzle. An ultrasonic cleaning chamber is fixedly located at one corner of the bottom of the body compartment.

[0006] In a preferred embodiment, the rotating component includes a connecting disk, which is fixedly connected to the outer wall of the motion module. A rotating groove is formed at the top of the connecting disk near the outer side. A rotating column is slidably connected inside the rotating groove. A pushing component is damped and sleeved on the top of the rotating column. The rotating component and the elastic component are connected through the pushing component.

[0007] In a preferred embodiment, the pushing assembly includes a rotating rod with a sleeve groove at one end near the rotating column. The rotating rod is damped and sleeved onto the top of the rotating column through the sleeve groove, and the rotating rod has a "J" shaped structure. An installation cavity is formed at the end of the rotating rod away from the rotating column, and the elastic component is located inside the installation cavity.

[0008] In a preferred embodiment, the elastic component includes a spring located inside the mounting cavity, with connecting rods fixedly connected to both ends of the spring. The connecting rods are slidably connected to the inner wall of the mounting cavity, and one end of the connecting rod away from the spring extends to the outside of the mounting cavity and is fixedly connected to the clamping plate.

[0009] In a preferred embodiment, the nozzle has symmetrical lugs fixedly connected to both sides, and the bottom of the clamping plate has a sliding groove at a position corresponding to the lugs. The clamping plate is slidably engaged with the outer wall of the lugs through the sliding groove.

[0010] In a preferred embodiment, the side walls and doors of the cabin are both made of transparent glass.

[0011] The technical effects achieved by this utility model are as follows: When disassembling the nozzle, this device eliminates the need for hand contact with the hot nozzle due to the clamping plate, thus reducing the probability of burns to workers and minimizing safety hazards. It also reduces the difficulty of disassembling the nozzle, making it easier to remove and, consequently, more convenient for the ultrasonic cleaning chamber to clean it. Attached Figure Description

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0018] Please see the appendix Figures 1 to 6 As shown, this utility model provides a multi-nozzle 3D printer with a self-cleaning idle nozzle, including a body chamber 1. A motion module 3 is provided at the top inside the body chamber 1, and an internally threaded connecting sleeve 4 is provided at the bottom of the motion module. A nozzle 5 is connected to the internal thread of the internally threaded connecting sleeve 4. The bottom of the nozzle 5 extends to the outside of the internally threaded connecting sleeve 4. A chamber door 2 is provided on the front of the body chamber 1. A rotating component is provided on the outer wall of the motion module 3. An elastic component is provided at the end of the rotating component away from the motion module 3. A clamping plate 13 is fixedly connected to the end of the elastic component near the nozzle 5. The clamping plate 13 is made of a high-temperature resistant material, and an anti-slip layer made of the same high-temperature resistant material is provided on the opposite side of the two clamping plates 13. The clamping plate 13 extends to both sides of the nozzle 5. An ultrasonic cleaning chamber 17 is fixedly provided at one corner of the bottom inside the body chamber 1.

[0019] In the above structure, when the nozzle 5 needs to be cleaned, the two clamping plates 13 can be pressed, and the two clamping plates 13 can clamp the nozzle 5 through the action of the elastic component. At this time, the nozzle 5 can be rotated around the nozzle 5 as the center by the action of the rotating component, so as to remove the nozzle 5 from the inside of the internal threaded connecting sleeve 4. After the nozzle 5 is removed, the elastic component and the clamping plates 13 can be removed. At this time, the nozzle 5 clamped by the clamping plates 13 can be placed into the ultrasonic cleaning chamber 17. The ultrasonic cleaning chamber 17 automatically cleans the nozzle 5 placed inside, realizing the self-cleaning of the nozzle 5. In the above manner, when disassembling the nozzle 5, since the disassembly is carried out through the clamping plate 13, there is no need for the hands to come into contact with the high temperature of the nozzle 5, thereby reducing the probability of workers being burned when disassembling the nozzle 5, thus reducing the safety hazards of disassembling the nozzle 5, reducing the difficulty of disassembling the nozzle 5, making it easier to disassemble the nozzle 5, and thus making it easier for the ultrasonic cleaning chamber 17 to clean the nozzle 5.

[0020] In a preferred embodiment, please refer to Figure 3 The rotating component includes a connecting plate 6, which is fixedly connected to the outer wall of the motion module 3. A rotating groove 7 is provided at the top of the connecting plate 6 near the outer side. A rotating column 8 is slidably connected inside the rotating groove 7. A pushing component is damped and sleeved on the top of the rotating column 8. The rotating component and the elastic component are connected through the pushing component.

[0021] In this embodiment, when the nozzle 5 is disassembled, the pushing component can be pushed so that the pushing component drives the rotating column 8 to rotate along the trajectory of the rotating groove 7 inside the rotating groove 7. During the rotation of the pushing component and the rotating column 8, the pushing component drives the clamping plate 13 to rotate. Thus, the nozzle 5 is disassembled from the inside of the internal threaded connecting sleeve 4 by the clamping plate 13 that holds the nozzle 5 during the rotation, thereby completing the disassembly of the nozzle 5.

[0022] Secondly, please refer to it again. Figures 3 to 5 The pushing component includes a rotating rod 9. A sleeve groove 15 is provided at one end of the rotating rod 9 near the rotating column 8. The rotating rod 9 is damped and sleeved to the top of the rotating column 8 through the sleeve groove 15. The rotating rod 9 has a "J" shaped structure. An installation cavity 10 is provided at one end of the rotating rod 9 away from the rotating column 8. The elastic component is located inside the installation cavity 10.

[0023] In the above structure, when the nozzle 5 is disassembled, the rotating rod 9 can be pushed to rotate along the trajectory of the rotating groove 7. The rotating rod 9 drives the rotating column 8 to rotate inside the rotating groove 7. The rotating rod 9 drives the clamping plate 13 that holds the nozzle 5 to rotate, thereby causing the clamping plate 13 to drive the nozzle 5 to rotate, thus completing the disassembly of the nozzle 5.

[0024] Secondly, please refer to the following as well. Figure 4 and Figure 5 The elastic component includes a spring 12, which is located inside the mounting cavity 10. Connecting rods 11 are fixedly connected to both ends of the spring 12. The connecting rods 11 are slidably connected to the inner wall of the mounting cavity 10. The end of the connecting rod 11 away from the spring 12 extends to the outside of the mounting cavity 10 and is fixedly connected to the clamping plate 13.

[0025] With the above structure, when disassembling the nozzle 5, the clamping plates 13 located on both sides of the nozzle 5 can be pressed, so that the opposite ends of the two clamping plates 13 slide inside the mounting cavity 10, and the spring 12 is compressed. At this time, the two clamping plates 13 clamp the nozzle 5 on the side close to the nozzle 5. Then, the clamping plates 13 can be rotated along the rotating groove 7, so that the clamping plates 13 drive the nozzle 5 to rotate, thereby completing the disassembly of the nozzle 5.

[0026] In a preferred embodiment, please refer to Figure 5 and Figure 6 The nozzle 5 has symmetrical lugs 16 fixedly connected to both sides. The bottom of the clamping plate 13 is provided with a sliding groove 14 at the position corresponding to the lugs 16. The clamping plate 13 is slidably engaged with the outer wall of the lugs 16 through the sliding groove 14.

[0027] In this embodiment, the clamping plate 13 near the nozzle 5 can be mounted by the cooperation of the sliding groove 14 and the lug 16. At the same time, when the two clamping plates 13 are pressed, the clamping plates 13 drive the sliding groove 14 to slide on the outer wall of the lug 16, and the clamping plate 13 is guided by the cooperation of the sliding groove 14 and the lug 16.

[0028] Secondly, please refer to it again. Figure 1 and Figure 2 The side walls of the fuselage compartment 1 and the compartment door 2 are both made of transparent glass.

[0029] The above structure allows observation of the working process inside the fuselage compartment 1 through the side wall and door 2, making it easier to understand the working situation inside the fuselage compartment 1.

[0030] The working principle of this utility model is as follows: When it is necessary to disassemble the nozzle 5, the nozzle 5 can be heated to a high temperature. After heating, the two clamping plates 13 can be pressed, causing the clamping plates 13 to move the connecting rods 11 closer to each other. At this time, the opposite ends of the two connecting rods 11 slide inside the mounting cavity 10, the spring 12 is gradually compressed, and the end of the connecting rod 11 close to the nozzle 5 clamps the nozzle 5. At this time, the clamping plates 13 can be rotated along the trajectory of the rotating groove 7, thereby unscrewing the nozzle 5 from the internal threaded connecting sleeve 4. After unscrewing the nozzle 5, the clamping plates 13 can be pushed upward, thereby causing the clamping plates 13 to push the rotating rod 9 upward and disengage from the rotating column 8. At this time, the ultrasonic cleaning chamber 17 can be opened, and the nozzle 5 clamped by the clamping plates 13 can be placed inside the ultrasonic cleaning chamber 17. The ultrasonic cleaning chamber 17 automatically cleans the nozzle 5, realizing the self-cleaning of the nozzle 5.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model shall be implemented according to conventional methods in the art unless otherwise specified or limited.
