Abstract
Description
Technical Field
[0001] The present application relates to the technical field of molding manufacturing equipment, and in particular to a printing device for 3D printing products. Background Art
[0002] 3D printing technology is an emerging rapid prototyping technology that uses digital models as the basis and uses materials such as powdered metal or plastic to construct objects by printing layer by layer.
[0003] Common metal printing equipment mainly includes a machine body, a support table, a powder spreading device and a sintering device. The support table is used to support the product, and the powder spreading device is used to lay the raw materials layer by layer on the support table. The sintering device can move in the vertical or horizontal direction and is used to sinter the raw materials in a specific area. During the printing process, the metal powder is spread on the support table by the powder spreading device, and then the sintering device sinters at a specific position. After sintering is completed, the powder is spread again and sintered again to complete the printing of the product.
[0004] After the product is printed, it is buried in metal powder. Workers are required to use suction equipment or a bucket to remove the dust around the product and then take the product out. This process places a heavy workload on workers and reduces efficiency. Utility Model Content
[0005] In order to improve the efficiency of 3D printing of metal products, the present application provides a printing device for 3D printed products.
[0006] The present application provides a 3D printing product printing device that adopts the following technical solution:
[0007] A printing device for 3D printed products comprises a device body and a support platform arranged inside the device body, wherein the support platform comprises a fixed platform and a movable platform, wherein a plurality of leak holes are opened on the upper edge of the fixed platform in a direction parallel to the fixed platform, a plurality of the movable platform are arranged corresponding to the leak holes and embedded in the leak holes, and the movable platform can slide in a direction perpendicular to the fixed platform and detach from the leak holes.
[0008] By adopting the above technical solution, the movable table is embedded in the leak hole during the printing process to form a support table with a flat surface for spreading powder and printing. After printing is completed, the movable table is moved to disengage from the leak hole, so that the fixed table forms a mesh structure, so that the raw materials on the support table can fall under the fixed table, so that the raw materials on the movable table are dumped and fall downward. It avoids the staff from using suction equipment or funnels to clean the raw materials around the product, which makes it convenient for the staff to take out the product, reduces the labor burden of the staff, and improves production efficiency.
[0009] Optionally, a sliding assembly is provided on one side of the movable table, and the sliding assembly includes a sliding block slidably connected to the fixed table, and a plurality of sliding blocks are provided corresponding to the movable table, and the movable table is connected to the sliding block.
[0010] By adopting the above technical solution, the sliding block can drive the movable table to slide, thereby realizing the sliding connection between the movable table and the fixed table.
[0011] Optionally, the sliding assembly further includes a linkage rod, and the linkage rod is connected to the plurality of sliding blocks simultaneously.
[0012] By adopting the above technical solution, the linkage rod is connected to the multiple sliding blocks at the same time, and the sliding linkage rod can drive the multiple sliding blocks to move at the same time, thereby facilitating the staff to adjust the positions of the multiple moving platforms.
[0013] Optionally, a connecting rod is provided between the sliding block and the moving platform, one end of the connecting rod is connected to the moving platform, and the other end is rotatably connected to the sliding block, and rotating the connecting rod can drive the moving platform to rotate.
[0014] By adopting the above technical solution, the sliding block is slid to separate the movable table from the leak hole. After the movable table is separated from the leak hole, the connecting rod can be rotated to drive the movable table to rotate, so that the movable table is tilted. After the movable table is tilted, the raw materials on the movable table can automatically slide off. Reducing the residual raw materials on the movable table is convenient for printing again.
[0015] Optionally, the sliding components are provided in two groups, and the two groups of sliding components are respectively provided on both sides of the moving platform.
[0016] By adopting the above technical solution, the sliding components guide the movable table to slide on both sides of the movable table, thereby improving the stability of the movable table during sliding.
[0017] Optionally, a rotation control assembly is provided on the fixed platform, and the rotation control assembly includes a paddle and a stopper, wherein the paddle is fixedly connected to the connecting rod parallel to the movable platform, and the stopper is located below the movable platform, and the connecting rod is moved downward so that the stopper can abut against the paddle.
[0018] By adopting the above technical solution, after printing is completed, the linkage rod drives the sliding block to move downward, and the movable table is separated from the leak hole, and the block abuts against the paddle. At this time, as the sliding block continues to move, the block can drive the paddle to rotate, and then drive the movable table to rotate automatically.
[0019] Optionally, the rotation control assembly also includes a reset member and a limit member, which define the rotation of the connecting rod driving the shift plate to approach the stop block as reverse rotation. The reset member is used to keep the connecting rod in the trend of reverse rotation, and the limit member is installed on the fixed platform to prevent the connecting rod from rotating in the reverse direction when the shift plate is parallel to the fixed platform.
[0020] By adopting the above technical solution, the sliding block is moved in the direction away from the stopper, and the reset member can drive the connecting rod to rotate in the opposite direction. When the dial plate is parallel to the fixed table, the movable table is also parallel to the fixed table. At this time, the limiter can prevent the connecting rod from continuing to rotate in the opposite direction, so that the movable table remains parallel to the fixed table, which facilitates the movable table to be embedded in the leak hole.
[0021] Optionally, the reset member is a spiral spring, one end of which is fixedly connected to the connecting rod, and the other end of which is fixedly connected to the fixed platform.
[0022] By adopting the above technical solution, one end of the spiral spring is fixedly connected to the connecting rod, and the other end is fixedly connected to the fixed platform, so that the connecting rod can maintain a tendency to rotate.
[0023] In summary, the present application includes the following beneficial technical effects: a plurality of leak holes are provided on the fixed table to form a mesh structure, and when the movable table is embedded in the leak holes, a support table with a flat surface is formed to support the raw materials. When the movable table is slid to separate the movable table from the leak holes, the raw materials on the support table can fall to the bottom of the fixed table with the movable table, and the product is supported by the fixed table, so that it is convenient for the staff to peel the product from the raw materials, reduce the labor burden of the staff, and improve work efficiency.

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-4 This application is described in further detail.
[0030] The embodiment of the present application discloses a printing device for 3D printing products.
[0031] Reference Figure 1 and Figure 2 A printing device for 3D printing products includes a device body 1 and a support table 2 located inside the device body 1. The support table 2 includes a fixed table 21 and a movable table 22. The fixed table 21 is a plate-like structure, and a plurality of leakage holes 23 are opened on the fixed table 21 in a direction parallel to the fixed table 21. The movable table 22 is provided with a plurality of leakage holes 23 corresponding to the leakage holes 23, and the movable table 22 is embedded in the leakage holes 23 to form a complete plate-like structure for supporting products and raw materials. The movable table 22 can move in a direction perpendicular to the fixed table 21 and detach from the leakage holes 23. After the movable table 22 detaches from the leakage holes 23, the raw materials (here, metal powder) located on the fixed table 21 can fall below the fixed table 21, so that the product leaks out automatically, reducing the labor burden of the staff and improving work efficiency.
[0032] Reference Figure 2 and Figure 3 , a sliding assembly 3 is arranged on the fixed table 21, and the sliding assembly 3 includes an extension plate 31, a plurality of sliding blocks 33 arranged corresponding to the movable table 22, and a plurality of connecting rods 34. The extension plate 31 is arranged on one side of the movable table 22 parallel to the arrangement direction of the movable table 22. The side wall of the extension plate 31 close to the movable table 22 is flush with the side wall of the leakage hole 23, and the extension plate 31 and the fixed table 21 are integrally formed. A sliding groove 32 is provided on the side of the extension plate 31 close to each other, and the length direction of the sliding groove 32 is perpendicular to the fixed table 21 and extends to the side wall of the leakage hole 23. The sliding block 33 is slidably connected in the sliding groove 32 along the length direction of the sliding groove 32, and one end of the connecting rod 34 is connected to the sliding block 33, and the other end is welded to the movable table 22. The sliding sliding block 33 can drive the movable table 22 to slide, so that the movable table 22 is separated from the leakage hole 23.
[0033] Reference Figure 2 and Figure 3 The connecting rod 34 is a cylindrical rod-shaped structure, and a rotation groove 35 is provided on the sliding block 33. The end of the connecting rod 34 away from the movable table 22 is inserted into the rotation groove 35 and can rotate around its own axis. When the sliding block 33 is slid downward, when the movable table 22 is separated from the leak hole 23, the movable table 22 can be rotated to tilt the movable table 22, thereby reducing the occurrence of residual raw materials on the movable table 22.
[0034] Reference Figure 2 and Figure 3The sliding assembly 3 also includes a linkage rod 36, which is arranged parallel to the fixed platform 21, and the linkage rod 36 is welded to the multiple sliding blocks 33 at the same time. The sliding linkage rod 36 can drive the multiple sliding blocks 33 to slide at the same time, which is convenient for the staff to synchronously adjust the positions of multiple moving platforms 22. In this embodiment, the movement of the linkage rod 36 is directly driven by an electric push rod (not shown in the figure), and in other embodiments, it can also be driven by a cylinder or other driving member. In order to improve the stability of the moving platform 22 during sliding, the sliding assembly 3 is set to two groups, and the two groups of sliding assemblies 3 are respectively set corresponding to two mutually parallel sides of the moving platform 22.
[0035] Reference Figure 2 and Figure 3 A mounting cavity 4 is also provided on one side of the extension plate 31 near the movable platform 22. A rotation control assembly 5 is provided in the mounting cavity 4. The rotation control assembly 5 includes a dial plate 51 and a stopper 52. The dial plate 51 is provided along the radial direction of the connecting rod 34 and is parallel to the movable platform 22. The stopper 52 is located below the dial plate 51. When the sliding block 33 slides downward, the dial plate 51 can abut against the stopper 52. As the sliding block 33 moves downward, the stopper 52 can drive the dial plate 51 to rotate, thereby causing the movable platform 22 to rotate automatically.
[0036] Reference Figure 2 and Figure 4 The rotation control assembly 5 also includes a reset member 53 and a limit member 54. Figure 2 , the rotation of the connecting rod 34 driving the dial plate 51 to approach the stopper 52 is defined as reverse rotation, and the reset member 53 is used to keep the connecting rod 34 in the trend of reverse rotation. In this embodiment, the reset member 53 is a spiral spring, which is sleeved on the connecting rod 34, and one end of the spiral spring is welded to the connecting rod 34, and the other end is welded to the sliding block 33. When the sliding block 33 slides downward, the stopper 52 overcomes the elastic force to make the connecting rod 34 rotate forward (forward rotation refers to rotation opposite to reverse rotation). When the sliding block 33 slides upward, the reset member 53 automatically drives the connecting rod 34 to rotate in the reverse direction. The limit member 54 is fixedly connected to the sliding block 33. When the dial plate 51 is parallel to the fixed table 21, the limit member 54 is located directly below the dial plate 51, thereby preventing the connecting rod 34 from rotating in the reverse direction. Under the action of the reset member 53 and the limit member 54, when the sliding block 33 moves upward, the movable table 22 can automatically reset to a position parallel to the fixed table 21, so that the movable table 22 is conveniently embedded in the leak hole 23.
[0037] The implementation principle of a printing device for 3D printed products in an embodiment of the present application is as follows: after the product is printed, the electric push rod is controlled by the PLC program to operate, so that the linkage rod 36 moves downward. When the movable table 22 is separated from the leak hole 23 and there is a certain gap between the movable table 22 and the fixed table 21, the dial plate 51 abuts against the block 52. At this time, the linkage rod 36 continues to slide downward, which can drive the multiple connecting rods 34 to rotate forward, thereby causing the raw materials to slide off, making it convenient for the staff to clean the raw materials on the support table 2, reducing the labor burden of the staff and improving work efficiency.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
