Description
Technical Field
[0001] The utility model relates to the technical field of 3D printers, and particularly relates to a scraping platform for 3D printing models. Background Art
[0002] A 3D printer, that is, a three-dimensional printer, is a device that can manufacture three-dimensional objects by means of layer-by-layer stacking and accumulation according to digital model files. It melts the printing wire through a nozzle and prints it layer by layer on a printing bed to form a required model. The process of three-dimensional printing generally includes the following steps: obtaining a three-dimensional model suitable for the printer, slicing the three-dimensional model to generate G-code (instructions that the 3D printer can understand), the printer printing the model according to the G-code instructions, and trimming the printed model, where trimming the printed model includes removing the printed model from the printing bed, removing the support of the model, and polishing and buffing it.
[0003] The inventor of the present application found that when removing the printed model from the printing bed, for some difficult-to-remove printed parts, the operator needs to use a spatula or a crowbar to separate it from the printing bed. During the operation, the operator needs to control the printing bed (printing bottom plate) taken out from the printer with one hand, and operate the spatula or crowbar with the other hand to separate the model from the printing bed. During this process, the spatula or crowbar is likely to cause harm to the operator. When the model is about to be separated, the operator has no time to fix the model, and the model is likely to fall to the ground and cause damage. During this process, under the operation of the spatula or crowbar, the model is likely to generate debris and residues that are not easy to clean and pollute the working environment. Therefore, the problem that the inventor of the present application solves is how to ensure the cleanliness of the working environment when separating the model by fixing the printing bed. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a scraping platform for 3D printing models, and the specific technical solutions are as follows:
[0005] A scraping platform for 3D printing models includes: a mounting bracket, which forms a mounting surface. The height of the four-side area of the mounting surface relative to the support surface is A, and the height of the middle area of the mounting surface relative to the support surface is B, where A > B; a scraping component arranged on the mounting surface, which includes: at least three limit buckles, which form a structure for fixing the printing bed. The high area of the limit buckle is close to the four-side area of the mounting surface, and the low area of the limit buckle is close to the middle area of the mounting surface; and a residue through-hole arranged in the low area of the limit buckle.
[0006] Further, the slope formed by connecting the four-side area of the mounting surface and the middle area of the mounting surface through a smooth curve is H, and the slope of the limit buckle is I, where H = I.
[0007] Preferably, the limiting area surrounded by the limiting buckles is rectangular, and the size of the rectangle is the same as that of the printing bed. The cross-section of the limiting buckle is L-shaped, and a cavity is formed between the limiting buckle and the mounting surface. The height of the cavity is the same as the thickness of the printing bed.
[0008] Furthermore, at least a part of the residue passing area formed by the residue through holes does not coincide with the limiting area surrounded by the limiting buckles, and the residue passing area does not coincide with the lower area of the limiting buckles.
[0009] Preferably, a collection assembly is further included, and the collection assembly includes: a residue collection box disposed below the mounting surface, a cavity is formed in the residue collection box, and the cavity communicates with the rectangular area surrounded by the limiting buckles through the residue through holes; a tool collection box disposed below the mounting surface, a cavity for placing tools is formed in the tool collection box; and a garbage receiving box disposed in the middle area of the mounting surface, an open cavity is formed in the garbage receiving box. The residue collection box is slidably connected to the mounting bracket, and the tool collection box is slidably connected to the mounting bracket.
[0010] It can be seen from the above technical solutions that the present utility model has the following beneficial effects:
[0011] The present utility model limits the planar movement of the printing strip through the limiting buckles at the left and right and front and rear positions, and limits the spatial movement of the printing strip through the L-shaped structure of the limiting buckles, so that the relative position between the printing strip and the mounting surface remains unchanged. It can free the hands of the operator to separate the model on the printing strip, improving the stability and safety during the separation process. Secondly, H = I and the residue through holes are formed in the lower area of the limiting buckles, so that the residues generated during the separation process can roll from the printing bed towards the middle area of the mounting surface by themselves. During this process, the residues can fall into the residue collection box through the residue through holes, improving the efficiency and quality of collecting residues in this embodiment.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", "upper", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0017] As Figure 1 shown, the embodiment of the present utility model includes a mounting bracket 1. The mounting bracket 1 is formed with a mounting surface 11. The height of the four-side region of the mounting surface 11 relative to the supporting surface is A, and the height of the middle region of the mounting surface 11 relative to the supporting surface is B, where A > B. A scraping component 2 is provided on the mounting surface 11. The scraping component 2 includes: at least three limit buckles 21, which are formed with a structure for fixing the printing bed. The high region of the limit buckle 21 is close to the four-side region of the mounting surface 11, and the low region of the limit buckle 21 is close to the middle region of the mounting surface 11. And a residue through-hole 22 is provided in the low region of the limit buckle 21.
[0018] Specifically, the top surface of the mounting bracket 1 is the mounting surface 11, and the mounting surface 11 is in a shape that is low in the middle and high around. This can make the residues falling on the mounting surface 11 tend to roll towards the middle region. Secondly, in this embodiment, six limit buckles 21 are provided at each station. Two on the left are used to limit the left movement of the printing bed, two on the right are used to limit the right movement of the printing bed, and two close to the middle region are used to limit the movement of the printing bed towards the middle region. It can fix the printing bed on the mounting surface 11, facilitating the operator to use a spatula or a crowbar with both hands to separate the model on the printing bed, improving the flexibility and safety of the operation.
[0019] When the printing bed is fixed on the installation surface 11 by the limit buckle 21, the lower area of the limit buckle 21 is the lower area of the printing bed, which is close to the middle area with a lower height of the installation surface 11. The higher area of the limit buckle 21 is the higher area of the printing bed, which is close to the four-sided area with a higher height of the installation surface 11, so that the inclination angle of the printing bed is the same as that of the limit buckle 21. Furthermore, during the process of separating the model, the generated residues can roll along the inclined surface of the printing bed towards the middle area of the installation surface 11 by themselves.
[0020] Immediately afterwards, the residue through-hole 22 is arranged in the lower area of the limit buckle 21, that is, in the lower area of the printing bed. It enables the residues generated during the process of separating the model to fall into the residue through-hole 22 during the process of rolling towards the middle area, playing a role in collecting residues and avoiding the situation of working environment pollution during the process of separating the model.
[0021] Furthermore, there are six scraping components 2, and the scraping components 2 are symmetric about any middle line of the installation surface 11.
[0022] Specifically, the six limit buckles 21 are axisymmetric, and the residue through-holes 22 are also axisymmetric and have the same axis of symmetry as the limit buckles 21. The distribution of the six scraping components 2 is one on the left, one on the right, and two on the front side and the rear side respectively, which makes the multi-station distribution of the operation platform more reasonable. Furthermore, the slope of each scraping component 2 is the same as the slope of the installation surface 11.
[0023] Furthermore, it further includes a collection component 3. The collection component 3 includes: a residue collection box 31 arranged below the installation surface 11, the residue collection box 31 forms a cavity, and the cavity communicates with the rectangular area surrounded by the limit buckle 21 through the residue through-hole 22; a tool collection box 32 arranged below the installation surface 11, the tool collection box 32 forms a cavity for placing tools; and a garbage storage box 33 arranged in the middle area of the installation surface 11, the garbage storage box 33 forms an open cavity.
[0024] Specifically, in this embodiment, the collection component 3 includes six residue collection boxes 31, two tool collection boxes 32 and one garbage storage box 33. The distribution mode of the residue collection boxes 31 corresponds to the positions of the scraping components 2. The scraping components 2 correspond to the middle areas of the residue collection boxes 31, so that the residues falling into the residue collection boxes 31 through the residue through-holes 22 all fall into the middle areas of the residue collection boxes 31, which makes the accumulation of residues in them more concentrated, facilitating the operator to scrape the residues accumulated in the middle to the surrounding areas and improving the residue-containing capacity of the residue collection boxes 31.
[0025] Secondly, the tool collection box 32 is respectively placed in the middle positions of the residue collection boxes 31 on the front and back sides. This distribution method enables the tool collection box 32 to obtain a larger installation space without affecting the distribution of the scraping component 2 and the residue collection boxes 31, thereby increasing the accommodation space of the tool collection box 32, enabling it to hold more tools for scraping and repairing the outer surface of the model, and improving the working efficiency of the operator.
[0026] Secondly, the garbage containment box 33 is placed in the middle area. The operator uses the flat-nose pliers in the tool collection box 32 to remove the support structure on the model. The removed support structures are centrally placed in the garbage containment box 33, which facilitates the cleanliness of the operation platform. The garbage containment box 33 forms a detachable connection with the mounting bracket 1 through an outward folding structure, which facilitates the operator to take out the garbage containment box 33 at any time to centrally process the removed support structures inside it.
[0027] Furthermore, the residue collection box 31 is slidably connected to the mounting bracket 1, and the tool collection box 32 is slidably connected to the mounting bracket 1.
[0028] Specifically, the residue collection box 31 is slidably connected to the mounting bracket 1 through a slide rail, which enables the residue collection box 31 to be conveniently separated from the mounting bracket 1, so as to take out the residue in the residue collection box 31. The tool collection box 32 is also slidably connected to the mounting bracket 1 through a slide rail, which enables the operator to conveniently take out the tools inside it to process the model. However, the slide rail of the tool collection box 32 has a limiting function, and the tool collection box 32 cannot be separated from the mounting bracket 1, but can only be pulled out or retracted from the mounting bracket 1 to prevent the tool collection box 32 from falling and injuring the operator's feet when it is pulled out, causing an accident.
[0029] Furthermore, the slope formed by connecting the four-side area and the middle area of the mounting surface 11 through a smooth curve is H, and the slope of the limit buckle 21 is I, where H = I.
[0030] Specifically, the shape of the mounting surface 11 is a smooth downward convex curve, which enables the residue to roll towards the middle area unobstructed. H = I enables the inclination angle of the limit buckle 21 to reach the maximum within the range specified by the mounting bracket 1, thereby enabling the inclination angle of the printing bed to reach the maximum within the structural range, enabling the residue on the printing bed to obtain as large a component of gravity as possible, and enabling as much residue as possible to roll off and fall into the residue through hole 22 by itself, improving the efficiency of collecting residue in this embodiment.
[0031] As Figure 2 shown, the limiting area surrounded by the limit buckles 21 is rectangular, and the size of this rectangle is the same as the size of the printing bed.
[0032] Specifically, the rectangular size is equal to the size of the printing bed, enabling close contact between the printing bed and the limit buckle 21. When an operator uses a spatula or a crowbar to separate the model on the printing bed, the printing bed will not move back and forth within the rectangular area surrounded by the limit buckle 21, which may affect the separation process and may damage the model. Therefore, the same size of the two can improve the efficiency and quality of separating the model.
[0033] Further, the cross-section of the limit buckle 21 is L-shaped, and a cavity is formed between the limit buckle 21 and the mounting surface 11, and the height of the cavity is the same as the thickness of the printing bed.
[0034] Specifically, the printing bed is fixed on the mounting surface 11 by the long side of the L-shaped limit buckle 21, and the height of the cavity is equal to the length of the short side of the L-shaped limit buckle 21. The same height of the two enables the limit buckle 21 to restrict the movement of the printing bed in the direction of the mounting surface 11, further restricting the degree of freedom of the printing bed and improving the stability of the printing bed during the process of an operator separating the model.
[0035] Further, at least a part of the residue passing area formed by the residue through-hole 22 does not coincide with the limit area surrounded by the limit buckle 21, and the residue passing area does not coincide with the lower area of the limit buckle 21.
[0036] Specifically, the residues generated by separating the model all roll from the rectangular area surrounded by the limit buckle 21 towards the middle area. The position of the residue through-hole 22 relative to the limit buckle 21 needs to satisfy that all the residues rolling out of the rectangular area can pass through the residue through-hole 22, so that they fall into the residue collection box 31 through the residue through-hole 22, improving the efficiency and quality of collecting residues in this embodiment.
[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
