Description

Technical Field

[0001] This utility model relates to the field of 3D printer accessories technology, specifically a melting component for melting 3D printer consumables. Background Technology

[0002] 3D printing, a type of rapid prototyping technology, is a technique that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. In short, 3D printing is a technology that creates three-dimensional objects by depositing materials layer by layer. It utilizes computer-generated 3D model data, and a 3D printer can stack powdered, liquid, or filamentary materials layer by layer to ultimately form a complete three-dimensional entity.

[0003] The 3D printer nozzle assembly is a crucial component of the printer. The nozzle melts the incoming filament and ejects it through the nozzle. When the filament enters the nozzle assembly, it only melts near the nozzle. If the filament melts above the heating element, it can easily cause blockage in the filament delivery path. Therefore, a heat dissipation structure is needed at the filament inlet area above the nozzle assembly. Traditional cooling methods, such as fan cooling, have limited heat dissipation, leading to insufficient melting of the filament above the heating element and subsequent nozzle blockage. To address this, we propose a 3D printer filament melting assembly with significantly improved heat dissipation, thus preventing the filament above the heating element from melting. Utility Model Content

[0004] This invention provides a melting component for melting 3D printer consumables, which has the advantage of rapidly cooling the feed tube and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A melting component for melting 3D printer consumables includes a heating base with a mounting hole. A nozzle is detachably provided at the bottom of the mounting hole. This application also includes a sealing shell disposed on the top of the heating base. A feed pipe is provided in the middle of the sealing shell. Both ends of the feed pipe are connected to the sealing shell and extend to the outside of both ends of the sealing shell. The bottom of the feed pipe is placed inside the top of the mounting hole. An exhaust port is provided on one side of the sealing shell, and a blower is provided on the other side. The blower is connected to the sealing shell through multiple ports. The free end of the blower is connected to a blower device through a pipe.

[0006] Preferably, one side of the sealed housing is an opening, and a sealing cap is detachably provided at the opening.

[0007] Preferably, the heating base is provided with a cylindrical hole for mounting a temperature sensor.

[0008] Preferably, the bottom of the sealed housing is mounted on the mounting base, and the edge of the mounting base is detachably connected to the heating base.

[0009] Preferably, the feed pipe is located between the blower pipe and the exhaust port, and multiple layers of heat sinks are provided on the surface of the feed pipe.

[0010] Preferably, the free end of the blower pipe is connected to the heat exchange tube via a pipe, and the free end of the heat exchange tube is connected to the blower via a pipe. The heat exchange tube is installed in the refrigeration device so that the air passing through the heat exchange tube is cooled.

[0011] Preferably, the refrigeration device includes two heat-conducting plates that can be detachably installed together. Each of the two heat-conducting plates has a curved receiving groove on its opposite surface, and a heat exchange tube is disposed in the receiving groove. At least one cooling plate is disposed on the surface of one of the heat-conducting plates, and a heat sink is disposed on the surface of the cooling plate.

[0012] Preferably, the surface of the heat-conducting plate is provided with a mounting groove corresponding to the cooling element.

[0013] Preferably, the two heat-conducting plates are placed inside the insulation shell, and the heating surface of the cooling element is located outside the insulation shell.

[0014] Compared with the prior art, when this utility model is used, the airflow generated by the blowing device is blown into the blowing pipe, and then the airflow is blown onto the surface of the feeding pipe through various ports.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a melting component for melting 3D printer consumables, including a heating seat 1, which is an aluminum heating seat or a steel heating seat. The heating seat 1 is provided with a mounting hole 13, and a nozzle 15 is detachably provided at the bottom of the mounting hole 13. Specifically, the top of the nozzle 15 is threadedly installed below the mounting hole 13.

[0024] The heating base 1 has a sealing shell 4 on top. The bottom of the sealing shell 4 is installed on the mounting base 2, and then the edge of the mounting base 2 is detachably connected to the heating base 1. Specifically, the four corners of the mounting base 2 are fixed to the heating base 1 with bolts, so that the sealing shell 4 and the heating base 1 can be fixed.

[0025] During use, the sealed housing 4 experiences rapid airflow. Therefore, a feed pipe 5 is located in the center of the sealed housing 4, coaxial with the sealed housing 4. The feed pipe 5 exchanges heat with the airflow. During installation, both ends of the feed pipe 5 must be connected to the sealed housing 4, with both ends extending outside the sealed housing 4. The bottom of the feed pipe 5 is positioned inside the top of the mounting hole 13, meaning the bottom of the feed pipe 5 is inserted into the top of the mounting hole 13. This ensures that once the mounting base 2 is fixed to the heating base 1, the bottom of the feed pipe 5 is stably positioned inside the top of the mounting hole 13, preventing any loosening or displacement even after prolonged use.

[0026] Furthermore, an exhaust port 17 is provided on one side of the sealed housing 4. There are multiple exhaust ports 17 arranged in a row. An air blowing pipe 7 is provided on the other side of the sealed housing 4. The air blowing pipe 7 is connected to the sealed housing 4 through multiple ports 6. The free end of the air blowing pipe 7 is connected to the air blowing device through a pipe. The air blowing device is specifically an air pump. The air blowing device blows the airflow generated by it into the air blowing pipe 7 through a conduit. Then the airflow blows into the interior of the sealed housing 4 through each port 6. Since the feed pipe 5 is located between the air blowing pipe 7 and the exhaust port 17, the airflow direction blows directly onto the surface of the feed pipe 5. The feed pipe 5 has a heat conduction function and is made of steel. The airflow can quickly blow the heat on the feed pipe 5 out of the exhaust port 17, so that the feed pipe 5 is cooled down.

[0027] like Figure 5 As shown, in order to better allow the surface of the feed pipe 5 to come into contact with the airflow, multiple layers of heat sinks 14 are provided on the surface of the feed pipe 5. The heat sinks 14 can quickly transfer the heat on the feed pipe 5 to the outside.

[0028] Furthermore, in practical applications, in order to lower the temperature of the air entering the sealed housing 4 and thus better cool the surface of the feed pipe 5, the free end of the blower pipe 7 is connected to the heat exchange pipe 9 through a pipe. The heat exchange pipe 9 is an aluminum or copper pipe, and its free end is connected to the blower device through a pipe. Since the heat exchange pipe 9 is located in the refrigeration device, the air passing through the heat exchange pipe 9 is cooled. This allows the airflow generated by the blower device to be cooled through the heat exchange pipe 9 before entering the sealed housing 4. Since the airflow temperature is relatively low, the cold airflow can better cool the feed pipe 5.

[0029] The specific components of the refrigeration device are described below, such as... Figure 3 As shown, the refrigeration device includes two detachably mounted heat-conducting plates 10, which are made of copper or aluminum. Specifically, the edges of the two heat-conducting plates 10 are fastened together with bolts. Curved receiving grooves 19 are provided on the opposing surfaces of the two heat-conducting plates 10. The receiving grooves 19 are arranged in an S-shape. During installation, the heat exchange tube 9 is placed inside the receiving groove 19. That is, when the two heat-conducting plates 10 are joined together, the receiving grooves 19 on the two heat-conducting plates 10 can fix the heat exchange tube 9, and at this time, the heat exchange tube 9 is located inside the receiving groove 19.

[0030] like Figure 1 and Figure 2As shown, after the two heat-conducting plates 10 are connected into a whole, they are placed inside the insulation shell 8, which is specifically a box made of foam, sponge, or other insulation material. At least one cooling fin 11 is provided on the surface of one of the heat-conducting plates 10, with the heating surface of the cooling fin 11 located outside the insulation shell 8. A heat sink 12 is provided on the surface of the cooling fin 11; the heat sink 12 is a heat pipe type heat sink, specifically the type used for motherboards in computer cases. During installation, the heat-conducting base at the bottom of the heat sink is placed on the heating surface of the cooling fin 11, and then the edge of the heat-conducting base is tightened to the heat-conducting plate 10 with bolts. It should be noted that the heat sink 12 is a heat pipe type heat sink, which has a good cooling effect, but a regular fan can also be used as the heat sink 12, as long as the surface temperature of the cooling fin 11 does not exceed 80℃.

[0031] Furthermore, to facilitate the installation of the cooling chips, mounting slots 18 corresponding to the cooling chips 11 are provided on the surface of the heat-conducting plate 10. The number of cooling chips 11 can be determined according to the actual situation. During installation, the cooling chips 11 are arranged in a matrix. When the heat-conducting seat of the radiator 12 is fixed, the heat-conducting seat can also press the cooling chips into the mounting slots 18.

[0032] Based on the above embodiments, further optimization can be made. In order to facilitate maintenance of the sealed housing 4, one side of the sealed housing 4 is made open, and a sealing cover 3 is detachably provided at the opening. The edge of the sealing cover 3 is fastened to the edge of the opening by bolts.

[0033] Based on the above embodiments, further optimizations can be made. To facilitate monitoring the heating temperature of the material by the heating seat 1, a cylindrical hole 16 for mounting a temperature sensor is provided on the heating seat 1. Furthermore, a temperature sensor is also provided on the heat-conducting plate 10 to monitor the cooling temperature of the heat-conducting plate 10.

[0034] Based on the above embodiments, further optimizations can be made. To facilitate the installation of the entire device, two mounting holes are provided on the mounting base 2. The mounting holes can be fastened to the printer with bolts, and the edge of the heat insulation shell 8 is also fastened to the printer with bolts.

[0035] The specific process is as follows: In actual application, the top of the feed tube 5 is connected to the feed pipe. The printed filament can be fed into the feed tube 5 through the feed pipe, and then the filament enters the heating seat 1, is melted, and is extruded from the nozzle 15. In reality, the diameter of the feed tube 5 must match the diameter of the filament. Since the temperature of the heating seat 1 will heat the filament in the feed tube 5, the rapidly flowing airflow inside the sealed outer shell 4 can quickly cool down the feed tube 5, preventing the filament inside the feed tube 5 from melting and causing the nozzle 15 to become clogged.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
