Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and in particular to a 3D printing device for metal buttons. Background Technology

[0002] Against the backdrop of the booming development of modern manufacturing, metal buttons, as key components in industries such as clothing, bags, and accessories, have extremely wide applications and play an important role in the functionality and aesthetics of products. Traditional metal button manufacturing processes rely on specific molds. From mold design and manufacturing to debugging, this not only significantly increases production costs and extends the production cycle, but also makes it difficult for traditional processes to meet the manufacturing requirements of metal buttons with complex shapes and stringent precision requirements. Even if they can be achieved, it comes at a high cost.

[0003] With the rise of 3D printing technology, its significant advantages, such as no need for molds, precise manufacturing of complex shapes, high material utilization, and short production cycles, have brought new directions to the manufacture of metal buttons. However, in practical applications, existing metal 3D printing equipment still faces technical bottlenecks when used for metal button manufacturing. One major bottleneck is that the containers holding the metal powder are usually stationary. During prolonged storage and use, the metal powder is prone to clumping. Clumped metal powder has significantly reduced fluidity, making it difficult to achieve ideal powder delivery and spreading during the printing process. This severely reduces the print quality of the metal buttons and also hinders the improvement of production efficiency. Therefore, addressing this deficiency in existing metal 3D printing equipment is key to improving the level of 3D printing manufacturing of metal buttons. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a 3D printing device for metal buttons, which can achieve the purpose of rotating the printing placement disk during printing and reciprocating the placement box, so as to agitate the free-flowing metal powder inside and prevent it from clumping and affecting the printing quality.

[0005] The technical solution adopted by this utility model is as follows: It includes a printing device body, the lower end of which is a hollow structure. A mounting box is provided on one side of the printing device body, and the mounting box is connected to the lower end of the printing device body.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0019] like Figures 1-5 As shown, this embodiment provides a 3D printing device for metal buttons, including a printing device body 1. The lower end of the printing device body 1 has a hollow structure. The printing device body 1 is model FS271M. The working principle is as follows: during printing, the piston of the powder cylinder rises and pushes out powder. The powder spreading device evenly spreads the powder on the printing placement disk 5. The printing placement disk 5 rotates to make the powder distribution more uniform. The laser system emits a laser beam to scan the powder layer according to the preset three-dimensional model slice data of the metal button. The scanned powder is heated and melted and fused with the lower layer. The printing placement disk 5 can also slowly rotate according to the program to assist the laser in multi-angle scanning and improve the printing quality. After each layer is scanned and melted, the printing placement disk 5 descends by one layer thickness. The powder spreading, scanning and melting process is repeated. The process involves layering and stacking metal powder until the metal button is formed. A mounting box 2 is provided on one side of the printing equipment body 1. The mounting box 2 is connected to the lower end of the printing equipment body 1. A reciprocating rotating component 3 is provided inside the mounting box 2 and the lower end of the printing equipment body 1. A motor 4 is provided at the lower end of the printing equipment body 1 to drive the reciprocating rotating component 3. A printing placement tray 5 is rotatably mounted on the printing equipment body 1. The printing placement tray 5 rotates in cooperation with the reciprocating rotating component 3. A placement box 6 for placing free-flowing metal powder is provided on the reciprocating rotating component 3. A pump body 7 is connected to the printing equipment body 1. The feed end of the pump body 7 is connected to the placement box 6. The output end of the pump body 7 is connected to a conveying pipe 8. The other end of the conveying pipe 8 is connected to the output end of the printing equipment body 1.

[0020] The reciprocating rotating assembly 3 includes a rotating shaft 301, a rotating shaft 302, and a fixed rod 303. The rotating shaft 301 is rotatably installed inside the lower end of the printing equipment body 1. The upper end of the rotating shaft 301 is fixedly connected to the printing placement tray 5, and the other end of the rotating shaft 301 is fixedly connected to the output end of the motor 4. The rotating shaft 302 and the fixed rod 303 are rotatably installed inside the mounting box 2. The rotating shaft 302 is fixedly connected to the placement box 6. A sprocket 304 is connected to the fixed rod 303 and the rotating shaft 301. A chain 305 meshes between the sprockets 304. A transmission gear 306 is connected to the fixed rod 303. The transmission gears 306 mesh with each other. A half gear 307 is fixedly installed on the fixed rod 303 and above the transmission gear 306. A rotating gear 308 is connected to the rotating shaft 302. The rotating gear 308 meshes with the half gear 307. The conveying pipe 8 is made of flexible hose. A sealing block 9 is plugged into the upper surface of the placement box 6.

[0021] In use, this invention involves connecting an external power source, removing the sealing block 9, pouring strictly screened and pre-treated free-flowing metal powder into the placement box 6, plugging the sealing block 9 into the placement box 6, starting the printing device body 1, and starting the pump body 7. The pump body 7 begins operation, drawing the free-flowing metal powder from the placement box 6 into the pump body 7 through the feed end. Subsequently, under the pressure of the pump body 7, the metal powder is transported along the conveying pipe 8 to the output end of the printing device body 1. After receiving the metal powder, the printing device body 1 processes it according to the pre-set 3D... The model data and printing parameters are used to precisely deposit metal powder layer by layer onto the print placement disk 5 through the internal print nozzle. Simultaneously, the motor 4 is activated, driving the rotating shaft 301 to rotate, which in turn rotates the print placement disk 5 fixedly connected to its upper end. This provides a suitable rotating platform for the printing operation, ensuring that the print placement disk 5 rotates to meet printing requirements. The sprocket 304 on the rotating shaft 301 rotates synchronously with the shaft 301, driving the sprocket 304 on the fixed rod 303 via the chain 305. This causes the fixed rod 303 to rotate, and the half gear 307 above the transmission gear 306 also rotates accordingly. When the toothed part of the half gear 307 meshes with the rotating gear 308 on the rotating shaft 302, it will drive the rotating shaft 302 to rotate, thereby causing the placement box 6, which is fixedly connected to the rotating shaft 302, to start rotating. As the fixed rod 303 continues to rotate, the toothless part of the half gear 307 gradually disengages from the rotating gear 308, and the placement box 6 stops rotating. The other half gear 307 meshes with the rotating gear 308, and the rotating gear 308 rotates in the opposite direction, thereby causing the placement box 6 to rotate in the opposite direction. This cycle repeats, realizing the reciprocating rotation of the placement box 6, effectively preventing the metal powder inside the box from clumping and always maintaining the good flowability of the metal powder.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
