Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, specifically a heat dissipation device for a 3D printer. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology. It is a technology that uses digital model files as a basis and employs powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital material printers, which are called 3D printers.

[0003] 3D printing involves heating and melting materials, then expelling them through nozzles, followed by cooling and solidification. However, when printing large objects or printing for extended periods, the large size of the object hinders heat dissipation and reduces airflow. As a result, the air absorbs heat and cannot dissipate quickly during heat exchange, preventing the object from cooling down. This excessively high temperature prevents the printing material from solidifying, easily leading to deformation and defective products. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model discloses a heat dissipation device for a 3D printer, including a printer structure 1, a spray gun heat dissipation structure 2 provided at the movable end of the printer structure 1, and a platform heat dissipation structure 3 provided at the side end of the printer structure 1.

[0022] An external power supply 4 and a control panel 5 are provided on the outside of the printer structure 1. The printer structure 1, the spray gun heat dissipation structure 2 and the platform heat dissipation structure 3 are electrically connected to the external power supply 4 and the control panel 5, respectively.

[0023] On the control panel 5, users can easily control the operating status of the entire cooling system, including turning the spray gun cooling structure 2 and the platform cooling structure 3 on or off, and adjusting the fan speed of the cooling fan 310. This design allows users to flexibly adjust the cooling strategy according to actual conditions, ensuring that the 3D printer maintains a suitable operating temperature throughout the printing process.

[0024] The printer structure 1 includes a mounting frame 101, a displacement device 102 is provided at the top of the mounting frame 101, a spray gun device 104 is provided at the movable end of the displacement device 102, a printing platform 103 is provided on the inner side of the displacement device 102, and the spray gun device 104 is located above the printing platform 103.

[0025] The displacement device 102 can drive the spray gun device 104 to move horizontally, thereby enabling precise spraying and material extrusion of the printed object at different positions on the printing platform 103. At the same time, the printing platform 103 is used to carry and support the object being printed, ensuring its stability during the printing process.

[0026] The platform heat dissipation structure 3 has two mounting platforms 301, which are located on both sides of the printer structure 1. A vertical slide rail 302 and a servo motor 304 are fixedly mounted on the top of each mounting platform 301. A transmission wheel 303 is rotatably connected to the inner side of the vertical slide rail 302. The output shaft of the servo motor 304 is connected to the transmission wheel 303 via a transmission belt 305. A sleeve block 306 is fixedly sleeved on the surface of the transmission belt 305. A lifting platform 307 is fixedly mounted on the front side of the sleeve block 306. A fixed frame 309 is provided on the front side of the lifting platform 307. A cooling fan 310 is provided on the inner side of the fixed frame 309.

[0027] Specifically, the spray gun heat dissipation structure 2 includes an external frame 201, the inner side of which is movably engaged with the outer side of the spray gun device 104, the inner side of which is provided with an installation recess 202, the inner side of which is rotatably connected with a hinged frame 203, and the inner side of the hinged frame 203 is provided with a cooling fan 204.

[0028] In this embodiment, when the cooling fan 204 is working, it generates airflow to cool the spray gun assembly 104, effectively reducing the temperature of the spray gun assembly 104 during operation and preventing overheating from affecting print quality. The design of the hinged frame 203 allows the cooling fan 204 to adjust its angle as needed, ensuring that the airflow can be evenly distributed across the surface of the spray gun assembly 104, thus improving heat dissipation efficiency.

[0029] Specifically, a follower block 308 is slidably connected to the surface of the vertical slide rail 302, and the front side of the follower block 308 is fixedly connected to the back side of the lifting platform 307.

[0030] In this embodiment, the sliding of the follower block 308 on the vertical slide rail 302 provides a stable lifting path for the lifting platform 307.

[0031] When the servo motor 304 starts, it drives the transmission wheel 303 to rotate through the transmission belt 305, which in turn drives the socket block 306 and the lifting platform 307 to move up and down along the vertical slide rail 302.

[0032] This design not only ensures the stability of the lifting platform 307 during the lifting process, but also achieves precise adjustment of the position of the cooling fan 310 through precise transmission control, enabling it to flexibly adapt to the height and shape of the printed object, thereby improving the targetedness and efficiency of heat dissipation.

[0033] Specifically, a protective net 311 is provided on the front side of the fixed frame 309, and the protective net 311 is located on the outside of the air outlet of the cooling fan 310.

[0034] In this embodiment, the protective net 311 is made of corrosion-resistant, high-strength material, capable of withstanding the airflow impact generated by the cooling fan 310 for extended periods, while preventing deformation or damage due to prolonged use. This design not only extends the service life of the protective net 311 but also ensures the stability and safety of the cooling fan 310 during operation. Furthermore, the mesh size of the protective net 311 is carefully calculated to effectively block external debris from entering without creating excessive resistance to the airflow generated by the cooling fan 310, thus maximizing the heat dissipation effect.

[0035] When in use, first input the printing information into the control panel 5, start the displacement device 102, the displacement device 102 drives the spray gun device 104 to move in the horizontal direction according to the preset printing path, and at the same time, the spray gun device 104 starts to perform material extrusion and spraying operations.

[0036] When heat dissipation is required, the user can start the servo motor 304 via the control panel 5. The output shaft of the servo motor 304 then begins to rotate, transmitting power to the transmission wheel 303 via the transmission belt 305. Upon receiving power, the transmission wheel 303 also begins to rotate, thereby driving the transmission belt 305 and its sleeve block 306 to move.

[0037] Since the socket block 306 is fixedly connected to the lifting platform 307, the lifting platform 307 will move up and down as the socket block 306 moves.

[0038] This lifting action is smooth and controllable, thanks to the cooperation of the vertical slide rail 302 and the follower block 308, which provide precise guidance and support for the lifting platform 307.

[0039] As the lifting platform 307 moves up and down, the cooling fan 310 inside the fixed frame 309 also changes position. The cooling fan 310 installed inside the fixed frame 309 at the front of the lifting platform 307 starts working, generating a strong airflow. The cooling fan 310 can flexibly adjust according to the height and shape of the printed material, ensuring that the airflow can be evenly blown on the surface of the printed material, achieving comprehensive and efficient heat dissipation. At the same time, the protective net 311 effectively prevents external debris from entering the cooling fan 310, ensuring its operational stability and safety.

[0040] In summary, this 3D printer's heat dissipation device, through the platform heat dissipation structure 3, utilizes a servo motor 304 to precisely control the transmission belt 305, thereby driving the socket block 306 to perform precise lifting and lowering movements. This allows the lifting platform 307 to adjust its height, enabling it to move up and down as needed. Through this reciprocating motion, the cooling fan 310 can comprehensively and evenly cool the entire outer wall of the printed object. This comprehensive cooling measure not only improves the heat dissipation effect but also significantly enhances heat dissipation efficiency. Therefore, the printed object can achieve better temperature control during production, better meeting actual production needs and ensuring a dual improvement in product quality and production efficiency.

[0041] It should be noted that the specific models and specifications of the displacement device 102, spray gun device 104, cooling fan 204, servo motor 304, cooling fan 310, external power supply 4 and control panel 5 in the 3D printer heat dissipation device need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] Furthermore, the power supply and principles of the displacement device 102, spray gun device 104, cooling fan 204, servo motor 304, cooling fan 310, external power supply 4 and control panel 5 in the 3D printer heat dissipation device are clear to those skilled in the art, and will not be described in detail here.
