Description

Technical Field

[0001] This application belongs to the field of 3D printing technology, specifically relating to a scraper device and a printer. Background Technology

[0002] 3D printers, also known as three-dimensional printers, are a type of cumulative manufacturing technology, or rapid prototyping technology. They are machines that use a digital model file as a basis and employ special waxes, powdered metals, or plastics and other adhesive materials to create three-dimensional objects by printing layers of adhesive materials.

[0003] The scraper assembly is a key component of a 3D printer. Its function is to evenly spread the material (such as photosensitive resin) through reciprocating motion, ensuring complete material coverage and preventing printing interruptions due to localized material shortages. The performance of the scraper assembly directly affects print quality and efficiency.

[0004] In related technologies, the scraper drive mechanism of a 3D printer can drive the scraper assembly of the scraper device to reciprocate within the material box via a transmission component, so as to spread the material evenly. However, the connection method between the scraper assembly and the transmission component is cumbersome, making the disassembly and assembly of the scraper assembly cumbersome. For example, the scraper assembly is generally connected to the transmission component by multiple screws and other fasteners. When the scraper assembly is damaged or needs cleaning and maintenance, multiple fasteners need to be removed one by one with the help of tools, making the disassembly and assembly of the scraper assembly cumbersome. Utility Model Content

[0005] The purpose of this application is to provide a scraper device and printer that can solve the problem of cumbersome disassembly and assembly of scraper components in related technologies.

[0006] In a first aspect, embodiments of this application provide a scraper device, the scraper device comprising: A scraper assembly, at least a portion of which is disposed within a material box; The connecting component includes a first connector and a second connector. The first connector is connected to the scraper assembly, and the second connector is connected to the transmission component. The second connector is movably connected to the first connector, and the second connector can switch between a first state and a second state. When the second connector is in the first state, the second connector is engaged with the transmission component. When the second connector is in the second state, the second connector is disconnected from the transmission component.

[0007] Secondly, embodiments of this application also provide a printer, the printer including a material box, a transmission component and the above-mentioned scraper device, at least a portion of the scraper assembly of the scraper device is located in the material box, and a second connector of the scraper device is connected to the transmission component.

[0008] In this embodiment, the second connector is movably connected to the first connector, and the second connector can switch between a first state and a second state. When installing the scraper assembly, simply switch the second connector to the first state to engage with the transmission component, easily connecting the scraper assembly to the transmission component. When maintenance, cleaning, or replacement of the scraper assembly is required, simply switch the second connector to the second state to disconnect it from the transmission component, allowing the scraper assembly to be easily and conveniently detached from the transmission component without the need for tools.

[0009] In this way, compared to using screws and other fasteners to connect the scraper assembly and the transmission component, no tools are needed when disassembling and assembling the scraper assembly. The operator only needs to switch the state of the second connector, making the disassembly and assembly simple, convenient, and easy. Attached Figure Description

Detailed Implementation

[0012] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0013] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] The scraper device and printer provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0015] refer to Figures 1-5 The scraper device provided in this application embodiment may include a scraper assembly 100 and a connecting assembly 300.

[0016] Among them, such as Figures 1-3 As shown, at least a portion of the scraper assembly 100 can be disposed within the material box 400. Specifically, at least a portion of the scraper assembly 100 can be located within the material storage trough of the material box 400 to facilitate scraping, leveling, and smoothing operations on the material.

[0017] In this embodiment, the printer may include a scraper drive mechanism, which is connected to the scraper assembly 100 via a transmission component 200. The scraper drive mechanism, through the transmission component 200, can drive the scraper assembly 100 to move within the material box 400, enabling the scraper assembly 100 to scrape, flatten, and level the material surface within the material box 400 according to a predetermined trajectory and movement. This provides a flat foundation for each layer of printing, thereby effectively improving the quality and accuracy of 3D printing. Here, the scraper drive mechanism can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, or other linear actuator.

[0018] like Figure 1 and Figure 3 As shown, the connecting component 300 may include a first connector 310 and a second connector 320. The first connector 310 may be connected to the scraper assembly 100, and the second connector 320 may be connected to the transmission component 200. The second connector 320 may be movably connected to the first connector 310, and the second connector 320 may switch between a first state and a second state.

[0019] When the second connector 320 is in the first state, the second connector 320 is engaged with the transmission component 200, thus enabling the connection between the scraper assembly 100 and the transmission component 200.

[0020] When the second connector 320 is in the second state, the second connector 320 is disconnected from the transmission member 200. In this way, the scraper assembly 100 can be easily separated from the transmission member 200 by separating the second connector 320 from the transmission member 200.

[0021] In this embodiment, since the second connector 320 is movably connected to the first connector 310, and the second connector 320 can switch between a first state and a second state, when installing the scraper assembly 100, simply switching the second connector 320 to the first state and engaging it with the transmission member 200 easily connects the scraper assembly 100 to the transmission member 200. When maintenance, cleaning, or replacement of the scraper assembly 100 is required, simply switching the second connector 320 to the second state and disconnecting it from the transmission member 200 allows the scraper assembly 100 to be easily and conveniently detached from the transmission member 200 without the need for tools.

[0022] In this way, compared with the method of connecting the scraper assembly 100 and the transmission component 200 by using screws or other fasteners, the connection structure between the scraper assembly 100 and the transmission component 200 is simple, which can effectively reduce the manufacturing cost of the scraper device. Moreover, when disassembling and assembling the scraper assembly 100, no tools are needed. The operator only needs to switch the state of the second connector 320. The disassembly and assembly operation is simple and convenient, and the disassembly and assembly difficulty is low.

[0023] In optional embodiments of this application, such as Figure 3 and Figure 5As shown, the connecting assembly 300 may further include an elastic element 340. The first end of the elastic element 340 can be connected to the first connecting member 310, and the second end of the elastic element 340 can be connected to the second connecting member 320, and can be used to keep the second connecting member 320 in a first state. With this configuration, when installing the scraper assembly 100, the operator only needs to place the scraper assembly 100 in the appropriate position, and the elastic element 340 can automatically drive the second connecting member 320 to switch to the first state using its own elasticity, completing the connection between the second connecting member 320 and the transmission member 200, thereby quickly achieving the connection between the scraper assembly 100 and the transmission member 200. Furthermore, after the scraper assembly 100 is connected to the transmission member 200, the elastic member 340 can continuously apply force to the second connecting member 320, so that the second connecting member 320 is always kept in the first state, that is, the second connecting member 320 is always kept in a state of tight engagement with the transmission member 200, thereby preventing the second connecting member 320 from disengaging from the transmission member 200 due to vibration or other factors, thus ensuring the stability of the connection between the scraper assembly 100 and the transmission member 200, so as to ensure the stability of the scraper assembly 100 when moving within the material box 400.

[0024] For example, the elastic element 340 can be a spring.

[0025] In other embodiments, the connecting component 300 may also exclude the elastic element 340.

[0026] In optional embodiments, such as Figure 3 As shown, the second connector 320 can be rotatably connected to the first connector 310 via a pivot 3202, such as... Figure 5 As shown, the second connector 320 may include a first snap-fit ​​portion 321 and an operating portion 322. The first snap-fit ​​portion 321 and the operating portion 322 may be located on opposite sides of the rotating shaft 3202, respectively. The elastic member 340 is located inside the first connector 310, and the second end of the elastic member 340 may be connected to the operating portion 322.

[0027] When the second connector 320 is in the first state, the first snap-fit ​​part 321 snaps into the transmission member 200 to realize the connection between the scraper assembly 100 and the transmission member 200.

[0028] When the second connector 320 is in the second state, the first snap-fit ​​portion 321 separates from the transmission member 200 to facilitate the separation of the scraper assembly 100 from the transmission member 200.

[0029] In this embodiment, the second connector 320 is connected to the first connector 310 via a rotating shaft 3202. The first locking part 321 and the operating part 322 are located on opposite sides of the rotating shaft 3202, which allows the second connector 320 to form a lever structure. Under the action of the elastic member 340, when the second connector 320 is in the first state, the first locking part 321 can generate a large locking force with the rotating shaft 3202 as the fulcrum, and tightly engage with the transmission member 200. When disassembling the scraper assembly 100, the operator only needs to apply force to the operating part 322 to overcome the elastic force of the elastic member 340, so that the second connector 320 rotates around the rotating shaft 3202, allowing the first locking part 321 to separate from the transmission member 200, and the second connector 320 can be switched to the second state. The scraper assembly 100 can be easily and conveniently separated from the transmission member 200 without the aid of tools, reducing the difficulty of disassembly and assembly. Furthermore, the second connector 320 is rotatably connected to the first connector 310 via a pivot 3202. Compared to the slidable connection between the second connector 320 and the first connector 310, the second connector 320 requires less space to move. In the rotatable connection, relying on the lever principle, only a small force is required to separate the second connector 320 from the transmission component 200.

[0030] In other embodiments, the second connector 320 may not be rotatably connected to the first connector 310. For example, the second connector 320 is slidably connected to the first connector 310. By moving the second connector 320, the second connector 320 can be engaged with or separated from the transmission member 200.

[0031] In an optional embodiment, when the second connector 320 is in the first state, the operating part 322 protrudes from the first connector 310. This configuration allows the operator to apply external force to the operating part 322 more conveniently and directly, reducing the difficulty of operation and improving the efficiency and accuracy of operation.

[0032] When the second connector 320 is in the second state, the operating part 322 is located inside or flush with the first connector 310. This arrangement provides the operator with feedback indicating that the operation is complete, allowing the operator to intuitively determine that the second connector 320 has reached the correct position.

[0033] In other embodiments, when the second connector 320 is in the first state, the operating part 322 may not protrude from the first connector 310. When the second connector 320 is in the second state, the operating part 322 may protrude from the first connector 310.

[0034] For example, the operating unit 322 can be a pressing unit. This design allows operators to trigger the operation simply by pressing it lightly with their fingers, just like pressing any other object, without needing to learn complex operating techniques. This effectively reduces the difficulty of operation and improves convenience and efficiency. Furthermore, when the operator presses the operating unit, they will feel clear tactile feedback. During the pressing process, the operator can feel the downward pressure and rebound of the operating unit. This tactile feedback allows the operator to clearly know whether their operation has been effective.

[0035] Optionally, a portion of the second connector 320 may be located within the first connector 310, thereby making the entire connecting assembly 300 more compact and effectively reducing its volume. Furthermore, the elastic member 340 may be located within the first connector 310, thus preventing it from being exposed to the external environment and easily damaged, and extending its service life.

[0036] For example, the first connector 310 may be provided with a cavity 313 and an opening 314, the opening 314 may communicate with the cavity 313, a portion of the second connector 320 may be located inside the cavity 313, and when the second connector 320 is in the first state, the operating part 322 of the second connector 320 may protrude from the first connector 310 through the opening 314 so that the operator can press the operating part 322.

[0037] Optionally, such as Figure 3 As shown, a limiting post 312 can be provided inside the first connecting member 310, and a portion of the elastic member 340 is sleeved outside the limiting post 312. The extending direction of the limiting post 312 can be consistent with the pressing direction of the operating part 322. With this configuration, the limiting post 312 can limit and guide the elastic member 340, ensuring that the elastic member 340 can only deform along the pressing direction of the operating part 322, and that the elastic member 340 can only apply elastic force to the operating part 322 in the opposite direction of the pressing direction, thereby ensuring that the second connecting member 320 can accurately switch between the first state and the second state.

[0038] In optional embodiments of this application, such as Figure 3 As shown, the scraper assembly 100 may include a scraper 110 and a scraper connector 120. The scraper 110 can be disposed within the material box 400; the scraper connector 120 can be connected to both the scraper 110 and the first connector 310. This arrangement facilitates the connection between the scraper 110 and the first connector 310.

[0039] Of course, the scraper assembly 100 may also exclude the scraper connector 120, with the scraper 110 directly connected to the first connector 310.

[0040] Optionally, the scraper connector 120 can be detachably connected to the scraper 110 and the first connector 310, respectively. This configuration allows for easy replacement of the damaged component when any one of the scraper 110, scraper connector 120, or first connector 310 is damaged, eliminating the need for complete replacement and thus reducing the maintenance cost of the scraper assembly.

[0041] In other embodiments, the scraper connector 120 may also be non-detachably connected to the scraper 110 and the first connector 310, respectively. Exemplarily, the scraper connector 120, the scraper 110, and the first connector 310 may be welded, cast, injection molded, or bonded into a single structure.

[0042] Optionally, such as Figure 3 and Figure 5 As shown, the scraper 110 can be provided with multiple through holes 111, and the through holes 111 can be distributed at intervals along the length of the scraper 110. This arrangement facilitates the passage of uncured material in the material box 400 through the scraper 110 when it moves, thereby reducing the resistance to the scraper 110.

[0043] In optional embodiments, such as Figure 4 and Figure 5 As shown, the scraper 110 may be provided with a connecting groove 112, and one end of the scraper connector 120 may be provided with a connecting shaft 123. The connecting shaft 123 can be embedded in the connecting groove 112, and in a first direction, the connecting groove 112 and the connecting shaft 123 are mutually restrictive and engaged. Here, the first direction may intersect the moving direction of the scraper assembly 100 and the length direction of the scraper 110. For example, the first direction is perpendicular to the moving direction of the scraper assembly 100 and perpendicular to the length direction of the scraper 110. In this embodiment, the connection between the scraper connector 120 and the scraper 110 is achieved through the restrictive engagement of the connecting shaft 123 and the connecting groove 112, making the connection structure between the scraper connector 120 and the scraper 110 simple and easy to assemble and disassemble. Furthermore, when the scraper 110 moves within the material box 400, the connecting shaft 123 is not easily dislodged from the connecting groove 112 due to the limiting effect of the groove wall, allowing the scraper connector 120 to stably drive the scraper 110 to move. Moreover, when disassembling the scraper assembly 100, the connecting shaft 123 is not easily dislodged from the connecting groove 112. Therefore, when separating the first connector 310 from the transmission component 200, the scraper 110 can be pulled out of the material box 400 along with the scraper connector 120, eliminating the need to separately remove the scraper 110 from the material box 400, making the disassembly operation simple and convenient.

[0044] In other embodiments, the connecting groove 112 may not be provided on the scraper 110, and the scraper connector 120 and the scraper 110 may be connected by fasteners such as screws.

[0045] In optional embodiments, such as Figure 4 and Figure 5 As shown, a limiting groove 113 can be provided on the scraper 110, and a portion of the scraper connector 120 can be located within the limiting groove 113, and will be limited and engaged with the groove wall of the limiting groove 113 in the moving direction of the scraper assembly 100. This arrangement can further improve the connection strength and stability between the scraper connector 120 and the scraper 110.

[0046] In other embodiments, the limiting groove 113 may not be provided on the scraper 110, and part of the scraper connector 120 may not be located within the limiting groove 113.

[0047] Optionally, such as Figure 5 As shown, the scraper connector 120 may include a first connecting plate 121 and a second connecting plate 122 connected to the first connecting plate 121. The first connecting plate 121 may be connected to the connecting shaft 123, and the second connecting plate 122 may be connected to the first connector 310. Furthermore, the first connecting plate 121 may be located in the limiting groove 113 and may engage with the groove wall of the limiting groove 113 in the moving direction of the scraper assembly 100.

[0048] In this embodiment, the length direction of the first connecting plate 121 can intersect with the length direction of the second connecting plate 122, and the length direction of the first connecting plate 121 can be the same as the length direction of the scraper 110. For example, the length direction of the first connecting plate 121 can be perpendicular to the length direction of the second connecting plate 122, and the length direction of the second connecting plate 122 can be parallel to the insertion direction of the first connecting member 310 and the transmission member 200. Here, the insertion direction of the first connecting member 310 and the transmission member 200 can be parallel to the depth direction of the material storage groove of the material box 400. This arrangement facilitates the scraper 110 to extend into the material box 400.

[0049] In some embodiments, such as Figure 1 and Figure 3 As shown, the connecting assembly 300 may further include a third connector 330. The third connector 330 may include a first part and a second part connected to the first part. The first part may be connected to the first connector 310, and the second part may extend into the material box 400 and be connected to the second connecting plate 122. This arrangement facilitates the connection between the scraper connector 120 and the third connector 330. Optionally, a space may be formed between the first part and the first connector 310 to avoid obstructing the side wall of the material box 400, so as to prevent the material box 400 from hindering the connection between the second connecting plate 122 and the third connector 330 and the movement of the scraper assembly 100.

[0050] For example, the second part and the second connecting plate 122 can be connected by means of bonding, riveting, insert connection, welding or snap-fitting.

[0051] In optional embodiments, such as Figures 3-5 As shown, the scraper assembly 100 may include a scraper 110, a first boss 130, and a second boss 140. The scraper 110 may be connected to the first connector 310. The first boss 130 and the second boss 140 may be respectively disposed near the two ends of the scraper 110 in the length direction. The first boss 130 and the second boss 140 may be used to slide in contact with two steps 410 inside the material box 400. In this embodiment, the sliding contact between the first boss 130 and the second boss 140 and the two steps 410 inside the material box 400 can provide guidance for the movement of the scraper assembly 100 inside the material box 400. Furthermore, during the movement of the scraper assembly 100, the sliding contact between the first boss 130 and the second boss 140 and the steps 410 can provide a certain buffering and stabilizing effect on the scraper assembly 100, preventing the scraper assembly 100 from shifting due to vibration or other factors, and helping to maintain the smoothness of the scraper assembly 100's movement.

[0052] It should be noted that both steps 410 are located inside the material box 400 and at the bottom of the material box 400. The two steps 410 are located on opposite sides of the material box 400. Along the direction from the two sides of the material box 400 to the center of the material box 400, the two steps 410 are inclined downward to avoid material accumulation or residue on the steps 410.

[0053] In other embodiments, the scraper assembly 100 may also include only the scraper 110.

[0054] Optionally, the first boss 130 and the second boss 140 can be detachably connected to the scraper 110. This arrangement facilitates replacement when the first boss 130 and the second boss 140 suffer wear, deformation, or other damage due to frequent sliding contact with the step 410.

[0055] Of course, the first boss 130 and the second boss 140 can also be non-detachably connected to the scraper 110.

[0056] Alternatively, both the first boss 130 and the second boss 140 can be made of plastic material, specifically PTFE (Polytetrafluoroethylene), to reduce friction during sliding. Of course, both the first boss 130 and the second boss 140 can also be made of metal.

[0057] In some embodiments, the first boss 130 and the second boss 140 can be detachably connected to the scraper 110 by means of fasteners such as screws.

[0058] And, as Figure 3 and Figure 5 As shown, both the first boss 130 and the second boss 140 may be provided with protrusions 131 extending along the length of the scraper 110. The scraper 110 may be provided with a first groove and a second groove. The first boss 130 may correspond to the first groove, and the protrusion 131 on the first boss 130 may be embedded in the first groove. Similarly, the second boss 140 may correspond to the second groove, and the protrusion 131 on the second boss 140 may be embedded in the second groove. In this embodiment, the cooperation between the protrusion 131 and the groove can improve the connection stability between the first boss 130 and the second boss 140 and the scraper 110. Furthermore, when installing the first boss 130 and the second boss 140, the protrusion 131 of the first boss 130 and the protrusion 131 of the second boss 140 can be first embedded into the first groove and the second groove respectively to pre-fix the first boss 130 and the second boss 140 onto the scraper 110. Then, the first boss 130 and the second boss 140 can be connected to the scraper 110 by screws or other fasteners. This helps to reduce the difficulty of disassembling and assembling the first boss 130 and the second boss 140. Precise alignment is not required when assembling the first boss 130 and the second boss 140, which simplifies the assembly operation.

[0059] Based on the scraper device provided in the embodiments of this application, the embodiments of this application also provide a printer. The printer may include a material box 400, a transmission member 200 and the scraper device described in any of the above embodiments. At least a portion of the scraper assembly 100 of the scraper device is located in the material box 400, and the second connector 320 of the scraper device may be connected to the transmission member 200.

[0060] The beneficial effects achieved by the printer provided in this application embodiment are consistent with the beneficial effects achieved by the scraper device provided in this application embodiment, and will not be repeated here.

[0061] In an optional embodiment of this application, one of the first connecting member 310 and the transmission member 200 of the scraper device may be provided with a slot 210, and the other may be provided with a plug-in part 311, which can be inserted into the slot 210. With this configuration, the first connecting member 310 and the transmission member 200 can be connected through the cooperation of the slot 210 and the plug-in part 311, thereby further improving the connection strength and stability between the scraper assembly 100 and the transmission member 200.

[0062] In other embodiments, the first connector 310 and the transmission member 200 may also omit the slot 210 and the plug-in portion 311.

[0063] In one way, such as Figure 3As shown, along the insertion direction of the plug-in portion 311, the width of the plug-in portion 311 gradually decreases in the second direction, and the width of the slot 210 also gradually decreases in the second direction. Here, the second direction can be perpendicular to the insertion direction of the plug-in portion 311 and can also be perpendicular to the moving direction of the scraper assembly 100. This arrangement facilitates the insertion of the plug-in portion 311 into the slot 210 during installation.

[0064] In other embodiments, the width of the plug portion 311 in the second direction may remain unchanged in the insertion direction of the plug portion 311, and the width of the slot 210 in the second direction may also remain unchanged.

[0065] In optional embodiments, such as Figure 3 As shown, the second connector 320 may include a first snap-fit ​​portion 321, and the transmission member 200 may be provided with a second snap-fit ​​portion 220. The first snap-fit ​​portion 321 may engage with the second snap-fit ​​portion 220 to make the second connector 320 engage with the transmission member 200.
