Description

Technical Field

[0001] The present invention relates to the technical field of 3D printers, and in particular to a model 3D printer for designing cultural and creative products. Background Art

[0002] With the continuous advancement of science and technology, 3D printing technology has developed rapidly in recent years. With its unique advantages, 3D printing technology has gradually emerged in various fields. In the field of cultural and creative product design, 3D printers can quickly transform designers' wild ideas into physical models, greatly improving design efficiency and the possibility of creative realization. It breaks through the limitations of traditional manufacturing processes and can accurately print various complex shapes and structures, providing strong technical support for the innovation of cultural and creative products. From the perspective of market demand, consumers' demand for personalized and unique cultural and creative products is growing. Traditional production methods often cannot meet such diverse needs. 3D printing technology can quickly customize various unique cultural and creative products according to different design requirements. Whether it is exquisite handicrafts, creative toys, or decorations with cultural characteristics, 3D printers can provide new ways for the design and production of cultural and creative products. However, the existing 3D printers for cultural and creative product design have some shortcomings in practical applications that cannot be ignored. Among them, one of the most prominent problems is that it is difficult to separate products. After printing, the products are often tightly adhered to the printing platform or support structure and are difficult to separate. This has brought many troubles to the production of cultural and creative products. First, the difficulty in separating products increases the difficulty and time cost of operation. After printing, the staff needs to spend a lot of time and energy trying to separate the products, which not only reduces production efficiency, but also may affect the entire production schedule. For some small cultural and creative enterprises or individual designers, the increase in time cost may have a certain impact on their business development. Secondly, During the separation process, the product is easily damaged, affecting its quality and appearance. Since the product is tightly adhered to the printing platform or support structure, scratches, breakages, etc. may occur during separation. For some cultural and creative products with high requirements on appearance, such damage is unacceptable. This will not only reduce the value of the product, but also may lead to customer dissatisfaction and complaints. At present, in order to solve the problem of difficult product separation, some methods have been tried, such as applying a separation agent on the printing platform. Although this method can reduce the adhesion between the product and the printing platform to a certain extent, the effect is limited. Moreover, applying a separation agent adds additional operating steps and costs, and may also cause certain pollution to the environment. Summary of the invention

The lifting column 13 slides through the limit groove 15 and its stroke is limited by the length of the limit groove 15, so that the support plate 14 at the upper end of the lifting column 13 is flush with the printing substrate 7 to ensure stable support of the product during printing.

[0030] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment discloses that the sealing box 20 is a hollow design with an opening at one end, and the outer surface of the open end of the sealing box 20 is in contact with the outer surface of the printed substrate 7, and the sealing box 20 is arranged opposite to the air guide groove 8; A tooth block is fixedly provided on the side surface of the piston gear rod 22 facing the sealing rotating seat 11, and a tooth block is fixedly provided on the outer side surface of the sealing rotating seat 11 facing the piston gear rod 22, and the sealing rotating seat 11 is meshed and connected with the piston gear rod 22 through the tooth block, and the upper end threads of the sealing rotating seat 11 on both sides of the piston gear rod 22 are in opposite directions; One end of the piston gear rod 22 penetrates the outer surface of the piston cylinder 23, and the piston gear rod 22 and the piston cylinder 23 are connected by sliding friction, and a spring is connected between the piston gear rod 22 and the piston cylinder 23; The two ends of the diversion hose 24 penetrate the piston cylinder 23 and the inner surface of the sealing box 20 respectively, and one end of the diversion hose 24 that penetrates the piston cylinder 23 is located at the end of the piston gear rod 22 away from the printing substrate 7; When printing is completed, cooling air is injected into the injection pipe 9 through the external nozzle 10 connected to the cooling air pipe. The cooling air is injected into the air guide groove 8 through the injection pipe 9. The air guide groove 8 guides the cooling air into the printed substrate 7 and discharges it from the other end of the air guide groove 8, so that the surface of the printed substrate 7 can be quickly cooled. At this time, with the inflow of cooling air, the air in the pressure chamber 12 inside the sealed rotating seat 11 is pre-cooled and contracted under the action of gas conduction in the heat conduction chamber 17, pushing the lifting column 13 to move downward until the lifting column 13 is blocked by the limit plate 16.

At this time, the cooling air injected through the air guide groove 8 is transmitted to the inside of the piston cylinder 23 through the guide hose 24 to push the piston gear rod 22 to slide. During the sliding process, the piston gear rod 22 drives the sealing rotating seat 11 to rotate by engaging with the connecting block 18. The sealing rotating seat 11 moves upward through the threaded connection with the printing substrate 7 and pushes the printed product upward off the printing substrate 7 through the support plate 14, thereby completing the separation of the product from the printing substrate 7.
