Technical Field

[0001] The utility model belongs to the technical field of additive processing devices, in particular to an additive processing device for ship parts. Background Art

[0002] Additive manufacturing is also known as rapid prototyping, 3D printing, and solid free-form manufacturing. These terms express the characteristics of additive manufacturing technology from different aspects. It uses a method of gradually accumulating materials to manufacture solid parts. Compared with traditional material removal manufacturing methods such as turning, milling, planing, and grinding, this technology is a "bottom-up" manufacturing method. Specifically, additive manufacturing devices construct three-dimensional solid models by stacking materials layer by layer, thereby realizing the manufacture of parts or products. Additive manufacturing devices are also used in ship parts.

[0003] In the process of manufacturing ship parts through additive manufacturing, if the platform is not used for a long time, dust will accumulate on the surface of the platform, thereby reducing the adhesion of the material, easily causing the unformed ship parts to shift, and there will also be some dripping material on the surface of the platform, which will affect the quality of the processing.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1, by Figure 1-4 The utility model relates to an additive processing device for ship parts, comprising a frame 1, an additive printing mechanism is provided at the top of the frame 1, a conveying roller 2 is symmetrically rotatably provided at the middle part of the frame 1, and the two conveying rollers 2 are connected by a conveyor belt 3. A conveying motor for driving the conveying roller 2 to rotate is also fixedly provided on the frame 1, a support plate 4 for supporting the conveyor belt 3 is fixedly provided on the frame 1, a box 5 is fixedly provided on the frame 1, and the box 5 is located below the conveyor belt 3. A first rotating shaft 6 and a second rotating shaft 7 are rotatably provided inside the box 5, a cleaning brush 8 is fixedly provided on the first rotating shaft 6, and a scraper 9 is fixedly provided on the second rotating shaft 7. A transmission gear 10 is fixedly provided at one end of the first rotating shaft 6 and one end of the second rotating shaft 7, and the two transmission gears 10 are meshed with each other, and the first rotating shaft 6 and the corresponding conveying roller 2 are connected by a transmission member.

[0021] The additive printing mechanism includes a print head and a conventional three-axis drive. When in use, the printed material is transported to the interior of the print head through an external pump body and then discharged. The discharged material is stacked by the print head to achieve the additive processing of ship parts, that is, to produce ship parts through 3D printing.

[0022] However, during the additive manufacturing process, some materials may fall onto the surface of the conveyor belt 3, and dust may also adhere to the surface of the conveyor belt 3. In order to deal with them, during operation, the conveyor motor drives the conveyor roller 2 to rotate, and the conveyor belt 3 is driven to move by the conveyor roller 2. At the same time, the conveyor roller 2 drives the first rotating shaft 6 to rotate through the transmission member, and the dust on the surface of the conveyor belt 3 is cleaned by the cleaning brush 8 on the first rotating shaft 6. At the same time, the transmission gear 10 on the first rotating shaft 6 drives the transmission gear 10 on the second rotating shaft 7 to rotate by meshing, so that the scraper 9 on the second rotating shaft 7 rotates, and the material attached to the surface of the conveyor belt 3 is removed by the scraper 9, which is more convenient.

[0023] Specifically, the transmission member includes two sprockets 11, which are respectively fixed on the first rotating shaft 6 and the corresponding conveying roller 2, and the two sprockets 11 are connected by a chain 12;

[0024] This design facilitates the movement of the two sprockets 11 through the transmission of the chain 12 , so as to realize the driving of the first rotating shaft 6 .

[0025] A fan 13 and a filter box 14 are fixedly provided on the outer wall of the box body 5. One end of the fan 13 is fixedly connected to the interior of the box body 5, and the other end of the fan 13 is fixedly connected to the interior of the filter box 14.

[0026] This design makes it easy to suck the dust in the box body 5 through the fan 13 and filter it through the filter box 14. The filtered air is discharged from the filter box 14, while the dust remains inside the filter box 14. The filter box 14 is equipped with a filter net or filter cotton, which is a conventional structure and will not be described in detail.

[0027] A collection box 15 is fixedly provided at the bottom end of the box body 5. The collection box 15 is in communication with the interior of the box body 5. A plurality of telescopic springs 16 are also fixedly provided on the inner bottom wall of the box body 5. The plurality of telescopic springs 16 are fixedly provided with a guide plate 17. The guide plate 17 is tilted inside the box body 5 so that one end thereof is located above the collection box 15.

[0028] A lever 18 is also fixedly provided on the first rotating shaft 6. The lever 18 is located at an end of the box body 5 away from the collection box 15. The length of the lever 18 is less than the length of the cleaning brush 8 and is in contact with the guide plate 17.

[0029] With this design, during use, the first rotating shaft 6 drives the lever 18 to rotate, and the lever 18 continuously squeezes the guide plate 17 during the rotation. Combined with the use of the telescopic spring 16, the guide plate 17 can be continuously vibrated, so that foreign objects falling on the guide plate 17 can fall into the interior of the collection box 15.
