Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D printing platform which is convenient to separate from a model. Background Art

[0002] 3D printing is an additive manufacturing technology. Its principle is to manufacture solid parts by the method of layer-by-layer accumulation of materials according to three-dimensional CAD drawing data. Therefore, when performing 3D printing, it is usually necessary to use a 3D printing platform to provide an attachment area for the production raw materials, which is convenient for 3D printing to form.

[0003] The prior art such as the utility model with the publication number of CN220594087U discloses a 3D printing platform, which includes a substrate, a heating layer, a heat insulation and heat preservation layer and a base arranged in sequence from top to bottom. The substrate is a porous metal plate evenly and densely provided with adhesion through holes, and the adhesion through holes penetrate through the substrate. The heating layer is used to heat the substrate, and the heat insulation and heat preservation layer is used to ensure the heat conduction to the substrate and prevent excessive heat conduction to the base. The substrate of the 3D printing platform of the utility model is a porous structure, and the support layer can be designed to adhere in different holes, so as to adjust the bonding strength between the printing material and the substrate, and there is no need to apply a layer of glue to fix the model, which can not only prevent the printing from warping and deforming, but also easily separate the model from the printing platform.

[0004] The above-mentioned and existing related technologies often have the following defects: for the 3D printing platforms in the prior art, a porous substrate is adopted to increase the bonding strength between the 3D printing material and the printing platform, so as to avoid the use of glue and facilitate the separation of the printed model. However, since the 3D printing material penetrates into the holes opened in the substrate, the printed 3D model has redundant parts, which need to be cut, resulting in low 3D printing efficiency.

By providing the adjusting screw 403, the position of the slicer 404 can be conveniently adjusted.

[0033] A motor 409 is installed on the side of the base 1. The output end of the motor 409 is fixedly connected to a rotating screw 408. One side of the "U" - shaped plate 401 close to the rotating screw 408 is fixedly connected to an adjusting plate 406, and the rotating screw 408 is threadedly inserted into the inner wall of the adjusting plate 406. By setting the motor 409, the rotation of the rotating screw 408 can be controlled. By setting the rotating screw 408, the movement of the adjusting plate 406 can be controlled, thereby controlling the movement of the "U" - shaped plate 401. One side of the base 1 close to the motor 409 is fixedly connected to a mounting block 410, and the mounting block 410 is fixedly connected to the motor 409. One side of the base 1 close to the rotating screw 408 is fixedly connected to a fixing plate 407, and the fixing plate 407 is rotatably connected to the rotating screw 408. By setting the mounting block 410, the motor 409 can be installed on the base 1. By setting the fixing plate 407, the stability of the rotating screw 408 during rotation can be improved.

[0034] As Figure 1 and Figure 2 as well as Figure 5 shown, the limiting device 5 includes two second sliders 51. Two second chutes are opened on the upper surface of the "U" - shaped plate 401, and both of the two second sliders 51 are slidably connected to the surfaces of the second chutes on the "U" - shaped plate 401. Clamping plates 52 are fixedly connected to the upper surfaces of both of the two second sliders 51. By setting the second sliders 51, the clamping plates 52 and the "U" - shaped plate 401 can be connected. By setting the clamping plates 52, the printed model can be limited.

[0035] Fixed rods 53 are slidably connected to the inner walls of both of the two second sliders 51. The fixed rods 53 are fixedly connected to the surfaces of the second chutes on the "U" - shaped plate 401. Springs 54 are sleeved on the surfaces of the fixed rods 53, and both ends of the springs 54 are fixedly connected to the second sliders 51 and the "U" - shaped plate 401 respectively.

Arc - shaped plates 55 are fixedly connected to the mutually - remote sides of both of the two clamping plates 52.

By setting the fixing screws 56 and the pressing plates 57, the position of the clamping plates 52 can be restricted.

[0036] Working principle: When printing is required, first move the substrate 2 close to the base 1, fix the substrate 2 with the fixing clip 3, and then move the base 1 close to the printing device. After the model printing is completed, rotate the adjusting screw 403 to make it rotate on the inner wall of the "U" - shaped plate 401 and the surface of the slicing plate 404, control the sliding rod 402 to slide on the inner wall of the "U" - shaped plate 401 and the slicing plate 404 to move close to the substrate 2. Start the motor 409 to drive the rotating screw 408 to rotate on the inner wall of the adjusting plate 406 and the surface of the fixing plate 407, so as to drive the "U" - shaped plate 401 to move close to the model through the adjusting plate 406. At the same time, the first slider 405 slides on the surface of the first chute on the base 1, so that the slicing plate 404 moves close to the model to cut the model. By setting the mounting block 410, the motor 409 can be connected to the base 1. By setting the cutting device 4, after the printing material is printed on the substrate 2, it is convenient to cut the printed - completed model, so that the redundant parts on the model can be separated, improving the printing efficiency.

[0037] During the process of cutting the printed model, when moving the "U" - shaped plate 401 close to the printed model, the model pushes the clamping plate 52 through the arc surface of the clamping plate 52 to drive the second slider 51 to slide on the surface of the fixed rod 53. Then the clamping plate 52 slides on the surface of the model. When the cutting of the model is completed, move the clamping plate 52 away from the model, rotate the fixed screw 56 to make it rotate on the inner wall of the arc - shaped plate 55, so that the abutting plate 57 moves close to the "U" - shaped plate 401 to limit the position of the clamping plate 52, and then remove the model. Then rotate the fixed screw 56 to make the abutting plate 57 away from the "U" - shaped plate 401. At this time, under the action of the elastic force of the spring 54, the two clamping plates 52 move closer to each other. By setting the limiting device 5, during the process of cutting the printed - completed model, the position of the model can be limited, so as to ensure the cutting effect of the model as much as possible and facilitate the cutting of the model.
