Description

Technical Field

[0001] This application relates to the field of ultrathin nano-insulation board production technology, specifically a material supply structure for the production of 3D printed ultrathin nano-insulation boards. Background Technology

[0002] Ultrathin nano-insulation panels have wide applications in energy conservation, and their high performance relies on the precise control of the material's microstructure and distribution through 3D printing technology. These panels are widely used in construction, aerospace, and electronic equipment. 3D printing technology, due to its ability to precisely control complex structures and material distribution, has become a key process for producing such high-performance insulation panels. However, in the process of 3D printing ultrathin nano-insulation panels, the performance of the material supply structure directly determines the uniformity, structural integrity, and thermal insulation performance of the finished product.

[0003] Current mainstream feeding technologies mostly employ a single discharge port, controlling the material flow rate at the port for precise feeding. However, because the discharge ports are uniform in shape, often cylindrical, their uniform cross-section design makes it difficult to meet diverse printing needs. When filling high-resolution areas, the excessively large discharge cross-section easily leads to material overflow, while at sharp edges, the rigid cross-section causes material shortages at the turning points. This severely restricts the efficiency of 3D printing ultrathin nano-insulation panels. Utility Model Content

[0004] This application provides a feeding structure for the production of 3D printed ultrathin nano-insulation panels, which can freely switch the feeding port and realize free feeding according to demand, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a feeding structure for the production of 3D printed ultrathin nano-insulation panels, including a linear motor one; a linear motor two is connected to the linear motor one via a slide table one, the linear motor two is arranged perpendicularly to the linear motor one, a cylindrical feeding cylinder is installed on the slide table of the linear motor two, a screw conveyor is installed inside the cylindrical feeding cylinder, a raw material box is installed at one end of the outer side of the cylindrical feeding cylinder, and a discharge cylinder that can be actively rotated is installed at the right end of the outer side of the raw material box, and a discharge nozzle one and a discharge nozzle two are provided on the outer side of the discharge cylinder, and a solenoid valve is installed on both the discharge nozzle one and the discharge nozzle two.

[0006] Specifically, the dual-nozzle and rotating design: the active rotation of the discharge cylinder 8 enables rapid switching between the conical nozzle and the strip nozzle, solving the problem that a single cylindrical discharge port cannot adapt to high-resolution filling and printing with sharp edges.

[0007] The screw conveyor 3 provides a constant pressure feeding foundation, and the solenoid valve 14 independently regulates the flow of the two nozzles, effectively reducing the discharge error and ensuring the uniformity of the ultra-thin sheet.

[0008] Preferably, there are two linear motors, which are arranged symmetrically one behind the other, and an electrically controlled telescopic rod is installed on the lower surface of each linear motor.

[0009] Specifically, the dual linear motor 12, linear motor 21, and electrically controlled telescopic rod 1 form a three-axis linkage system that tracks the print head position in real time, eliminates material accumulation or stringing defects at path turning points, and reduces the surface roughness of the board.

[0010] Preferably, the raw material box is installed on the upper left side of the outer side of the cylindrical feeding cylinder, and the upper surface of the raw material box is provided with an openable sealing cover.

[0011] Specifically, the top-mounted, openable, sealed cover facilitates cleaning of the silo and unblocking of the nano-slurry, reducing the problem of uneven composition caused by filler settling.

[0012] Preferably, the feed nozzle is a conical nozzle.

[0013] Specifically, the tapered tapered structure limits the material output section when printing micro-grooves / holes, preventing material overflow and effectively ensuring the forming accuracy of detailed structures.

[0014] Preferably, the second discharge nozzle is a strip-shaped nozzle.

[0015] Specifically, the flat strip nozzle expands the material coverage width, maintaining continuous material supply when printing sharp-angled transition areas, eliminating the risk of interlayer peeling caused by insufficient material at the edges.

[0016] Preferably, the right end face of the cylindrical feeding cylinder is provided with a sealing cover and a stepper motor, a gear one is installed on the outer side of the discharge cylinder, a gear two is installed on the output shaft of the stepper motor, the gear two meshes with the gear one, and both the gear two and the gear one are located inside the sealing cover.

[0017] Preferably, the discharge cylinder is sealed to the inner side of the cylindrical feeding cylinder via a sealing ring, and the discharge cylinder is rotatably connected to the sealing cover via a bearing.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1. This application achieves precise adaptive feeding: by integrating a conical discharge nozzle one and a strip-shaped discharge nozzle two through an actively rotatable discharge cylinder, combined with gear transmission and stepper motor control, the discharge nozzle can be switched according to the path requirements during the printing process;

[0020] 2. This application adopts a screw conveyor with dual solenoid valves for separate control: the screw conveyor provides basic constant pressure feeding to avoid flow fluctuations caused by pneumatic drive; the solenoid valves independently control the opening and closing of each discharge nozzle and the flow rate, matching the linear motor's moving speed;

[0021] 3. The discharge cylinder of this application achieves dynamic sealing with the cylindrical feeding cylinder through a sealing ring to prevent nanoparticles from entering the rotating mechanism; a three-degree-of-freedom motion system is composed of linear motor one (X-axis) → slide table one → linear motor two (Y-axis) → electrically controlled telescopic rod (Z-axis) to drive the feeding cylinder to track the position and posture of the print head in real time.
