Description

1376286 VI. Description of the invention: [Technical field to which the invention pertains] • This case relates to a dustproof device, and more particularly to a dustproof skirt suitable for a three-dimensional forming mechanism. [Prior Art] Rapid Prototyping (RP technology) is developed based on the concept of building a pyramid layer stacking. Its main technical feature is the rapid molding, without any tools, molds and Automatic and fast design of arbitrarily complex shapes in the case of fixtures

The fast-to-3D solid model' greatly shortens the development cycle of new products and reduces the cost of research and development, ensuring the success rate of new products and the development of new products. It is between technicians, technicians and enterprises. Policy makers, users of products and other non-technical personnel provide a more complete and convenient product flow collection tool, which significantly improves the competitiveness of products in the market and the rapid response of enterprises to the market. At present, the technology has developed a 3D solid model using the printing technology and the precise positioning technology of the carrier. The production method is to apply a layer of powder on top of the carrier and print the Gaoqing mixture on some powders by using the ink printing technology. The liquid 'make the glue liquid adhere to the powder and solidify' - repeat the above process layer to complete the 3D solid model. However, the printing equipment used by the conventional RP technology cannot be sealed without jetting, and the residual glue will be dried 1376286 in the maintenance station of the printing job, which will result in poor subsequent functional printing. Continue to print to produce high quality 3D products. Although the current RP technology is known as rapid prototyping technology, it takes hours or tens of hours to form, regardless of the size of the molded article or how to improve the equipment of the rapid prototyping device. In the finished product, when the print head itself is blocked, if it is not immediately determined or detected, it will cause irreparable time and material waste. In addition, when forming a high-viscosity adhesive liquid, the glue point is sprayed at a speed of up to 8 m/sec. In this ultra-high-speed spray, when the droplet sticks to the powder, the next side is not droplets. Sticky nano-sized small powder will rebound and fly, and when the powder is fed or picked up, the powder will fly everywhere when the powder pile is dropped. And the conventional equipment does not have the powder supply mechanism of the Dong. Pushing excess powder into the recovery cylinder will cause pollution and energy waste when the powder is dropped. In addition, it is necessary to wait for the molding drying time after each powdering, and wait for several hours to dry after molding, that is, if the forming strength is insufficient or • Inadvertently picking up may damage the finished product, so the molded product must be strong enough to be taken out, and the printing positioning accuracy cannot be achieved. Only one-way rapid powdering and printing can be performed to increase the total molding time. . • In addition, when the machine is left standing for a long time or the print head is removed, the sheets and seals in the maintenance station will stick to the adhesive and harden. Moreover, the conventional technology uses a one-way powder coating and a one-way printing device, and the one-way printing of the printing module firstly supplies powder from the origin to the end point, and then powders from the end point to the origin. Finally, printing from the origin to the end point, the pre-operation time is too long, and the time cannot be fully utilized. m 4 1376286 Therefore, how to develop a dustproof device suitable for a three-dimensional forming mechanism which can improve the above-mentioned conventional techniques is an urgent problem to be solved.
