Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printers, and in particular relates to a double-nozzle double-platform 3D printer. Background Art

[0002] In the field of 3D printing, dual-nozzle 3D printers are favored for their efficient printing capabilities and the ability to use two different materials at the same time. However, due to the dual-nozzle design, the heat generated during the printing process is more concentrated. If this heat cannot be dissipated in time, the temperature of the printer will be too high. Excessive temperature will not only affect the printing quality, but may also cause damage or burnout of the printer's components. For example, excessive nozzle temperature may cause other components to dissolve or deform, which in turn affects the accuracy and stability of the print. Traditional heat dissipation systems often fail to meet the needs of rapid heat dissipation, resulting in reduced print quality and shortened equipment life. In addition, the current method of installing a fan on the nozzle to cool down not only increases the weight of the print head and increases its inertia when moving, but also generally only uses smaller fans, such as 3010, 5010 and other fans, which are small in size and small in wind force, and can no longer fully meet the needs of rapid printing. Therefore, we need a new auxiliary heat dissipation method to meet the heat dissipation needs of dual-nozzle dual-platform 3D printers during printing. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0025] See also Figure 1-7As shown, the utility model is a dual-nozzle dual-platform 3D printer, including a printing box, a lifting molding platform 10, a dual-nozzle assembly 11, a feeding assembly 8 and a heat dissipation assembly, the printing box is provided with a box door 1 and a box cover 3, wherein the heat dissipation assembly includes a fan 12, an auxiliary heat dissipation member 2, a heat dissipation duct 13 and a guide blowing plate 9, the fan 12 has a group and is respectively installed on one side of the nozzle on the dual-nozzle assembly 11; the auxiliary heat dissipation member 2 has a group and is respectively installed on both sides of the printing box; the heat dissipation duct 13 is arranged inside the two sides of the printing box, and the heat dissipation duct 13 is connected to the auxiliary heat dissipation member 2; the guide blowing plate 9 is arranged at the bottom of the inside of the printing box and is located below the lifting molding platform 10, and the cold air sucked by the auxiliary heat dissipation member 2 is blown into the inside of the printing box from the guide blowing plate 9 via the heat dissipation duct 13, and then discharged through the air outlet 6 located at the top of the printing box.

[0026] In the utility model, from the overall structure point of view, the 3D printer is mainly composed of a printing box, a lifting molding platform 10, a dual nozzle assembly 11, a feeding assembly 8 and a heat dissipation assembly. The printing box is the skeleton of the entire printer, providing a closed and stable environment for the printing process. The design of the box door 1 and the box cover 3 allows the user to easily view and manage the printing process. In the core part of the printing, the dual nozzle assembly 11 and the feeding assembly 8 together constitute the print head of the printer. The dual nozzle design allows the printer to print two different materials at the same time, or increase the printing speed, greatly improving the printing efficiency. The feeding assembly 8 is responsible for accurately delivering the printing material to the nozzle.

[0027] The heat dissipation system includes a fan 12, an auxiliary heat sink 2, a heat dissipation duct 13, and a guide air blowing plate 9. The fan 12 is installed on the nozzle side of the dual nozzle assembly 11 and is responsible for cooling the nozzle. The auxiliary heat sink 2 is located on both sides of the printing box, and the auxiliary heat sink 2 can quickly cool the heat generated by the printer during operation.

[0028] The heat dissipation duct 13 is cleverly arranged inside the two sides of the printing box and is closely connected with the auxiliary heat dissipation element 2. With this design, the cold air generated by the fan can pass through the heat dissipation duct and blow evenly to the inside of the printing box. The guide blowing plate 9 is located at the bottom of the inside of the printing box, below the lifting molding platform 10. When the cold air is blown out from the heat dissipation duct 13, it will pass through the guide blowing plate 9, and through the air holes on the guide blowing plate 9, it will be further evenly distributed to ensure that the temperature inside the printing box is evenly distributed. At the same time, the cold air inhaled by the auxiliary heat dissipation element 2 is not only blown from the inside of the printing box, but also discharged through the air outlet 6 located at the top of the printing box. Such a design forms a complete heat dissipation cycle, effectively discharges the heat generated inside the printer, and ensures the stable operation of the printer.

[0029] In summary, the utility model dual-nozzle dual-platform 3D printer not only improves printing speed and efficiency, but also makes innovative design in the heat dissipation system. While cooling the printer, the auxiliary heat dissipation parts can reduce the burden of the nozzle heat dissipation system. This design ensures that the printer can maintain a stable temperature during operation, improves the printing quality, extends the service life of the printer, and ensures the normal operation of the dual-nozzle printer. At the same time, the dual-nozzle design also provides users with more printing options and flexibility.

[0030] like Figure 6-7 As shown: the auxiliary heat sink 2 includes a fixing seat 21 and a fan 22, the fixing seat 21 is fixedly connected to the outside of the printing box; the fan 22 is installed on the fixing seat 21, and a duct 23 is installed on one side of the fan 22, and the other side is connected to the heat dissipation duct 13 inside the printing box, and the duct 23 is externally connected to the cold air outlet of the refrigeration fan.

[0031] In this embodiment, the auxiliary heat sink 2 is mainly composed of a fixing base 21 and a fan 22. The fixing base 21 not only supports the fan 22, but also ensures the stability of the entire heat dissipation system by being fixedly connected to the outside of the printing box. This connection method can be screw fixing, welding or other mechanical connection methods, and the specific selection depends on the material and design requirements of the printing box.

[0032] The fan 22 is the core component of the auxiliary heat sink 2. It is installed on the fixing seat 21 and is responsible for introducing cold air into the interior of the printing box. An air duct 23 is installed on one side of the fan 22. This design allows the cold air to be guided through the air duct 23 to form a clear cold air channel. The other side of the air duct 23 is connected to the heat dissipation air duct 13 inside the printing box, ensuring that the cold air can smoothly enter the internal space of the printing box.

[0033] At the same time, the air duct 23 can be used for the cold air outlet of the external cooling fan, which means that the entire heat dissipation system not only relies on the natural convection generated by the fan 22, but also can provide additional cold air through the external cooling fan. This design can significantly improve the heat dissipation efficiency, especially when printing high-strength and high-temperature materials, it can effectively reduce the temperature in the printing box and prevent the influence of thermal stress on the printing quality and equipment life.

[0034] like Figure 1-2 As shown: transparent observation ports 4 are provided on both sides of the printing box, and heat dissipation fins 5 are provided on both sides of the observation ports 4. One end of the heat dissipation fins 5 is located inside the printing box, and the other end is located outside the printing box.

[0035] In this embodiment, transparent observation ports 4 are provided on both sides of the printing box. This design not only provides an intuitive observation window for the user, but also increases the convenience of operation of the device. The material of the observation port 4 is selected from a high-transparency material, so that the details of the printing process are clearly visible, and the user can monitor the printing progress and status at any time.

[0036] On both sides of the viewing port 4, heat dissipation fins 5 are carefully arranged. One end of the heat dissipation fin 5 extends deep into the interior of the printing box, and the other end extends to the outside of the box. This layout enables the heat dissipation fin 5 to effectively transfer the heat generated during the printing process from the inside of the box to the outside, thereby ensuring that the printing device can maintain a stable temperature during continuous operation and avoiding performance degradation or failure due to overheating.

[0037] In addition, the shape and arrangement of the heat dissipation fins 5 have also been carefully designed and optimized. They adopt a large-area thin-sheet structure to increase the heat dissipation area and improve the heat dissipation efficiency. At the same time, the spacing between the heat dissipation fins 5 has also been accurately calculated to ensure smooth air circulation, further enhancing the heat dissipation effect.

[0038] like Figure 1-2 As shown: there are two air outlets 6 and they are arranged on both sides of the box cover 3, a dust shield 7 is arranged above the air outlet 6, and a detachable filter is arranged inside the air outlet 6.

[0039] In this embodiment, there are two air outlets 6, which are located on both sides of the box cover 3. This layout not only ensures the uniformity of air circulation, but also makes the heat dissipation effect more outstanding. A dust shield 7 is cleverly arranged above the air outlet 6. This design not only effectively blocks the entry of dust and impurities, but also prolongs the service life of the equipment. A detachable filter is also arranged inside the air outlet 6. The filter can filter the air, effectively reducing the dispersion of particles inside the printer into the external environment, and reducing the pollution to the surrounding environment.
