Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing nozzle assembly that can be quickly disassembled and cleaned. Background Technology

[0002] 3D printing, a type of rapid prototyping technology, uses digital model files as a basis and employs bondable materials such as plastics and metals to construct objects layer by layer. This technology breaks through the limitations of traditional manufacturing, enabling the one-time molding of complex shapes and is widely used in industrial manufacturing, medical, and construction fields. For example, it can be used to manufacture customized medical devices and design unique architectural models. Its advantages lie in saving materials and shortening production cycles. With technological advancements, it will play a crucial role in more industries in the future, reshaping the manufacturing landscape.

[0003] The existing announcement number is CN221112873U, which describes a 3D printer that is easy to maintain. Through the structural design of disassembling components, it realizes the function of disassembling the print head. This solves the problem that when using a 3D printer to print models, the print head needs to be used to spray out the printing material to form the model. After the print head has been working for a long time, some impurities will be left inside. If the inside of the print head is not cleaned regularly, the long-term accumulation will affect the printing effect of the printer.

[0004] While existing 3D printing nozzles are easy to disassemble and clean, this only addresses the external parts of the nozzle. Critical areas such as the pipes connected to the nozzle may still be inadequately cleaned. Some residual printing material may adhere to the pipes, and even after disassembling the nozzle, ordinary cleaning methods are insufficient to completely remove these impurities. Long-term accumulation can still affect printing quality, leading to problems such as uneven filament output and nozzle clogging. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 3D printing nozzle assembly that can be quickly disassembled and cleaned.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] By using a tube and nozzle that are both threadedly connected to the heating block, and a frame consisting of a vertical rod and a ring at the nozzle that extends into the tube, when the nozzle is disconnected from the heating block and moves out along with the vertical rod and ring, the vertical rod and ring can carry out the residue inside the tube and clean it thoroughly. This reduces problems such as uneven filament output and nozzle clogging caused by long-term accumulation of impurities, ensuring high-quality output from 3D printing.

[0008] Preferably, a screw is rotatably connected to the heating block, and the screw is threadedly connected to the crank.

[0009] Preferably, the crank is adapted to the contact points of the two sets of hexagonal blocks.

[0010] Preferably, two sets of sliding rods are connected to the heating block, and both sets of sliding rods are slidably connected to the crank rod.

[0011] Preferably, the contact portions of the two sets of hexagonal blocks and the heating block are bonded with rubber pads.

[0012] Preferably, the rubber pad is made of nitrile rubber.

[0013] Preferably, a handle is connected to the screw.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By coordinating the heating block, nozzle, tube, vertical rod, and ring, and utilizing the threaded connection between the tube and nozzle to the nozzle at the heating block, and the frame formed by the vertical rod and ring at the nozzle extending into the tube, when the nozzle is disconnected from the heating block and moves out along with the vertical rod and ring, the vertical rod and ring can carry out the residue inside the tube, cleaning it thoroughly. This reduces problems such as uneven filament output and nozzle clogging caused by long-term accumulation of impurities, ensuring high-quality output from 3D printing.

[0016] 2. By using the combination of the hexagonal block, the crank rod, and the screw rod, the screw rod drives the crank rod to contact the surface of the hexagonal block, which can restrict the rotation of the pipe or nozzle caused by the hexagonal block. This can stably constrain the rotation of the hexagonal block, ensuring that the pipe and nozzle remain fixed under specific working conditions, and avoiding the impact on working accuracy and effect due to accidental rotation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figures 1 to 5 A 3D printing nozzle assembly that can be quickly disassembled and cleaned includes a heating block 1 with an opening 2. One end of the opening 2 is threadedly connected to a nozzle 3 and a tube 4, respectively. One end of the nozzle 3 is connected to a vertical rod 5, and two sets of vertical rods 5 are connected to multiple sets of rings 6. Both sets of vertical rods 5 and multiple sets of rings 6 are inserted into the tube 4. Hexagonal blocks 10 are connected to both the tube 4 and the nozzle 3. Two sets of hexagonal blocks 10 are in contact with the same curved rod 8. The hexagonal blocks 10 facilitate the threaded installation or removal of the tube 4 or the nozzle 3 using a wrench or the like. The nozzle 3 and the tube 4 are both threadedly connected to the opening 2 of the heating block 1. This connection method facilitates disassembly. When the nozzle 3 is disconnected from the heating block 1 and removed, the vertical rod 5 connected to one end of the nozzle 3 and the other end are connected to multiple sets of rings 6 and all of them are inserted into the tube 4. The vertical rod 5 and the rings 6 will carry out the residue inside the tube 4, thereby achieving a thorough cleaning of the inside of the tube 4. This effectively reduces problems such as uneven filament output and nozzle clogging caused by long-term accumulation of impurities, and ensures high-quality output of 3D printing.

[0025] In this embodiment, a screw 7 is rotatably connected to the heating block 1. The screw 7 is threadedly connected to the crank 8. The crank 8 is adapted to the contact points of the two sets of hexagonal blocks 10. When it is necessary to restrict the rotation of the tube body 4 and the nozzle 3, the screw 7 is rotated. The rotation of the screw 7 is converted into the linear motion of the crank 8. During the movement, the crank 8 will closely fit the surface of the hexagonal block 10, thereby generating pressure on the hexagonal block 10, thus restricting the hexagonal block 10 from driving the tube body 4 or the nozzle 3 to rotate. Two sets of sliding rods 9 are connected to the heating block 1. Both sets of sliding rods 9 are slidably connected to the crank 8. The sliding rods 9 provide a stable guiding effect for the movement of the crank 8, so that the crank 8 will not deviate during the movement, ensuring that it can accurately contact the hexagonal block 10 and apply a stable constraint force. Rubber pads 11 are adhered to the contact parts between the two sets of hexagonal blocks 10 and the heating block 1. The rubber pads 11 are made of nitrile rubber, which has excellent oil resistance, wear resistance and good elasticity. During the 3D printing process, the printing material may contain some oily components. The nitrile rubber pad 11 can effectively resist the corrosion of these oily substances and extend the service life of the rubber pad 11. Its good wear resistance ensures that the rubber pad 11 will not wear easily when the hexagonal block 10 moves relative to the heating block 1 or is subjected to vibration, and always maintains good anti-slip and cushioning performance. The elasticity of the rubber pad 11 allows it to fit tightly against the contact surface of the hexagonal block 10 and the heating block 1, further enhancing the friction and preventing the hexagonal block 10 from accidentally rotating the tube 4 or the nozzle 3. A handle 12 is connected to the screw 7.

[0026] The working principle of this embodiment is as follows: First, turn off the 3D printer power and wait for the equipment to cool to room temperature to avoid burns. After completion, locate the heating block 1. The tube 4 and nozzle 3 are both connected to the opening 2 of the heating block 1 via threads. Using a suitable tool (such as a wrench; if the nozzle is small, needle-nose pliers can be used), rotate the nozzle 3 to separate it from the threaded connection of the heating block 1. Since the frame formed by the vertical rod 5 and the ring 6 at the nozzle 3 extends into the tube 4, as the nozzle 3 rotates to disengage from the heating block 1, slowly pull the nozzle 3 outwards. The nozzle 3 will then move the vertical rod 5 and the ring 6 out together. At this time, the vertical rod 5 and the ring 6 can remove any residue adhering to the inside of the tube 4, achieving a thorough cleaning of the inside of the tube 4. If it is necessary to reinstall the nozzle 3, align the threads of the nozzle 3 with the threads of the opening 2 of the heating block 1, rotate the nozzle 3 until it is tightened, ensuring that the nozzle 3 is securely installed.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
