[0018] Solution 10, based on Solution 8 or Solution 9, the base is connected to the frame by sliding in a horizontal direction.
[0019] From the above description of the utility model and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:
[0020] 1. In scheme 1 and its preferred embodiment, a printing platform includes a base, a printing table, an adjustment member and a biasing member.
[0021] The base is provided with a through hole extending along the first direction, and the through hole is used for allowing a part of the adjusting member or the printing platform to pass through to achieve the connection between the two.
[0022] At least one of the printing table and the base is provided with an arc surface abutting against the other so that the printing table is suitable for universal rotation relative to the base, so that the printing table can adjust its angle relative to the base and the printing surface of the printing table is in a horizontal state relative to the print head.
[0023] At least one of the adjusting member and the printing table extends into the through hole and is connected to the other one. The adjusting member is provided with an abutting surface facing the base. The two ends of the biasing member act on the abutting surface and the base respectively to make the base and the printing table abut against each other. By applying force to the adjusting member, the printing table connected to the adjusting member is in close contact with the base, so that there is a damping force between the two, so that the angle will not be easily changed during the printing process.
[0024] Furthermore, the adjusting member is suitable for adjusting the position relative to the printing table along the first direction and stopping, thereby changing the distance between the abutting surface and the base, thereby adjusting the force applied by the biasing member to adjust the damping force to meet the use requirements.
[0025] When leveling, the print head can be used for leveling. When the print head reaches the center of the printing table, it moves relative to the printing table in a horizontal direction perpendicular to the first direction to push the printing table, so that the printing table can rotate universally relative to the base to level the surface of the printing table.
[0026] It can be seen that in an optional leveling method of this embodiment, the user can achieve adaptive leveling of the printing platform through the movement of the print head and / or the base without manual leveling, thereby reducing the difficulty of leveling operation.
[0027] 2. In the second scheme and its preferred embodiment, the adjusting member is suitable for being screwed or multi-stagely connected with the printing table to adjust the position relative to the printing table and dock, both of which can achieve corresponding functions, among which the screw connection method can achieve stepless adjustment of the damping force.
[0028] 3. In scheme three and its preferred embodiment, the base includes an arc boss, the arc boss is provided with a first arc surface protruding toward the printing table; the printing table is provided with an arc groove, the arc groove is provided with a second arc surface recessed in a direction away from the base; the first arc surface and the second arc surface are offset against each other, thereby realizing universal rotation of the two. Compared with only one arc surface, the method of having two arc surfaces makes the contact area between the printing table and the base larger, making the printing table more stable.
[0029] 4. In scheme 4 and its preferred embodiment, the diameter of the second arc surface is greater than or equal to the diameter of the first arc surface, ensuring that the two can rotate in all directions while the difference in printing position before and after rotation does not change too much, thereby facilitating printing operations.
[0030] 5. In scheme five and its preferred embodiment, the printing platform includes a mounting post, which extends into the through hole, and the size of the through hole is larger than the size of the mounting post; the adjusting member is connected to the mounting post to achieve the connection between the two.
[0031] 6. In the sixth scheme and its preferred embodiment, the through hole is provided with a through hole and a clearance hole, and the through hole can limit the maximum adjustment angle of the printing table. The clearance hole is arranged on the side close to the printing table, and the clearance hole is in the shape of a guide cone to prevent the through hole from interfering with the mounting column when the machining error of the mounting column causes the chamfer between the mounting column and the bottom of the arc groove to be too large, so that the base and the printing table cannot realize universal rotation or the first arc surface cannot fit the second arc surface.
[0032] 7. In the seventh solution and its preferred embodiment, if the center of the printing platform is too far from the fulcrum to form a cantilever, when there is a printed object at the center of the printing platform, the printing platform will be tilted by force, affecting the printing quality. In this embodiment, the via hole is directly opposite to the center of the printing platform, so that the base can support the center of the printing platform, reducing the possibility of the printing platform tilting due to the printed object.
[0033] 8. In scheme eight and its preferred embodiment, a printer includes a frame, a print head and a printing platform as described above, wherein the print head is suitable for sliding relative to the frame along a first direction to contact or move away from the printing platform, thereby achieving high degree of forming of a three-dimensional printed object.
[0034] 9. In scheme nine and its preferred embodiments, when the print head is against the center of the printing table, it moves relative to the printing table in a horizontal direction perpendicular to the first direction to push against the printing table, so that the printing table can be universally rotated relative to the base, so that the surface of the printing table can be leveled without manual leveling, which is simple and convenient.
[0035] 10. In Scheme 10 and its preferred embodiments, the base is connected to the frame by sliding in the horizontal direction, and also drives the printing table to slide, so as to realize the molding of the printed matter in at least one horizontal direction. When the print head also has the freedom of movement in the horizontal direction, the movement directions of the base and the print head can be perpendicular to each other, so as to realize flat printing, and can move simultaneously to increase printing efficiency.

[0049] A printer includes a printing platform, a frame, a slide frame and a printing head. Figure 1 The printing platform includes a base 1, a printing table 2, an adjusting member 3, and a biasing member 4.
[0050] The frame is used to install the printing platform and the printing head. The frame includes a guide post and a sliding rod. The guide post extends along a first direction 51, wherein the first direction 51 is Figure 5 In the up-down direction in the first direction 51, the sliding rod extends along the front-back direction 52 perpendicular to the first direction 51, and the front-back direction 52 is as shown in FIG. Figure 2 As shown. One guide post and one sliding rod may be provided, or multiple guide posts and sliding rods may be provided to ensure more stable movement. The sliding frame is slidably connected to the guide post along a first direction 51.
[0051] The print head is adapted to slide relative to the printing table 2 along a first direction 51 and also move relative to the printing table 2 along a horizontal direction perpendicular to the first direction 51. Specifically, the print head is mounted on a sliding frame, and the print head slides relative to the frame along the first direction 51 to approach or move away from the printing table 2 through the up and down movement of the sliding frame, thereby achieving high-level molding of the three-dimensional printed object. The print head is also slidably connected to the sliding frame along a left-right direction 53 perpendicular to the first direction 51, so as to achieve plane molding of the three-dimensional printed object on the printing table 2. The left-right direction 53 is as shown in FIG. Figure 5 shown.
[0052] refer to Figure 1 , Figure 2 , a printing table 2 is placed on the base 1, and the base 1 is slidably connected to the frame in the horizontal direction, and can drive the printing table 2 to move together (which will be described below); in this embodiment, the base 1 is slidably connected to the sliding rod along the front-back direction 52 to achieve movement in the front-back direction 52. Since in this embodiment, the base 1 also provides movement in one direction, the print head can achieve three-dimensional printing as long as it achieves movement in two directions.
[0053] The base 1 is provided with a through hole 11 extending along the first direction 51. The through hole 11 is directly opposite to the center of the printing table 2. The through hole 11 is provided with a through hole 111 and a clearance hole 112 which are connected to each other, wherein the clearance hole 112 is provided on a side close to the printing table 2, and the clearance hole 112 is in a guide cone shape, that is, the size of the clearance hole 112 is gradually reduced in the direction close to the through hole 111. The base 1 includes an arc boss 12, and the arc boss 12 is provided with a first arc surface 121 protruding toward the printing table 2.
[0054] refer to Figure 3, the printing table 2 is used to carry three-dimensional printed objects. At least one of the printing table 2 and the base 1 is provided with an arc surface that abuts against the other so that the printing table 2 is suitable for universal rotation relative to the base 1. In this embodiment, universal rotation means that the printing table 2 can rotate around three axes relative to the base 1 to change the angle between the printing table 2 and the base 1. In this embodiment, it is achieved by the cooperation of the ball head and the ball groove; in this embodiment, both are provided with arc surfaces. Specifically, the printing table 2 is provided with an arc groove 21, and the arc groove 21 is provided with a second arc surface 211 that is recessed in a direction away from the base 1; the second arc surface 211 and the first arc surface 121 are suitable for abutting against each other under the action of the biasing member 4 (which will be explained below). In this embodiment, preferably, the diameter of the second arc surface 211 is greater than or equal to the diameter of the first arc surface 121. The printing table 2 includes a mounting post 22, which protrudes from the bottom of the arc groove 21 and is suitable for extending into the through hole 11, and the size of the mounting post 22 is smaller than the size of the through hole 11, so that there is an adjustable gap between the two, so that the printing table 2 is suitable for being rotatable relative to the base 1, and the preferred size difference between the mounting post 22 and the through hole 11 is 0.5-1.5mm.
[0055] refer to Figure 4 , Figure 5 At least one of the adjusting member 3 and the printing table 2 extends into the through hole 11 and is connected to the other. In this embodiment, both have a portion extending into the through hole 11. The adjusting member 3 is provided with an abutting surface 311 facing the base 1. The adjusting member 3 is suitable for adjusting the position relative to the printing table 2 along the first direction 51 and docking to change the distance from the abutting surface 311 to the base 1. In this embodiment, the adjusting member 3 is screwed with the mounting post 22 to achieve position adjustment and docking along the first direction 51. Specifically, the adjusting member 3 includes a gasket 31 and a screw connection 32. The gasket 31 is provided with an abutting surface 311 and is seated on the screw connection 32. The screw connection 32 passes through the gasket 31 and is screwed with the mounting post 22 of the printing table 2.
[0056] The biasing member 4 applies a force to the printing table 2 to make it approach the base 1. In this embodiment, the biasing member 4 is a spring, and the two ends of the biasing member 4 act on the abutting surface 311 and the surface of the base 1 facing away from the printing table 2 respectively to make the base 1 and the printing table 2 abut against each other, so that the second curved surface 211 abuts against the first curved surface 121. In other embodiments, the biasing member 4 can also be composed of two mutually repelling magnets to act on the base 1 and the printing table 2 respectively. The closer the two magnets are, the greater the force, and vice versa, the smaller the force, which can also achieve a spring-like effect.
[0057] During leveling, the print head descends and contacts the center point of the printing table 2. The print head moves in the left-right direction 53 relative to the printing table 2. By pushing against the printing table 2, the printing table 2 is universally rotated relative to the base 1, so that the surface of the printing table 2 is leveled left-right. Similarly, the base 1 is moved in the front-back direction 52. During this process, the hole wall of the through hole 11 pushes against the mounting column 22 to make the printing table 2 move forward and backward, so that the surface of the printing table 2 is leveled front-back until the leveling action is completed. The adjustment member 3 can be adjusted before or after leveling to adjust the force of the biasing member 4. Under the force of the biasing member 4, the printing table 2 and the base 1 are in close contact, so that there is a large damping force, so that the angle will not change easily.
[0058] When printing, the print head first descends to the center point of the printing platform 2, stops descending after reaching the center point, and then moves back and forth and left and right relative to the printing platform 2 to start printing, and gradually rises until printing is completed.
[0059] Compared with the prior art, this embodiment has the following beneficial effects:
[0060] In an exemplary embodiment, a printing platform includes a base 1, a printing table 2, an adjustment member 3 and a biasing member 4.
[0061] The base 1 is provided with a through hole 11 extending along the first direction 51, and the through hole 11 is used for the adjustment member 3 or part of the printing table 2 to pass through to achieve the connection between the two. At least one of the printing table 2 and the base 1 is provided with an arc surface that abuts against the other so that the printing table 2 is suitable for universal rotation relative to the base 1, so that the printing table 2 can adjust the angle relative to the base 1, so that the printing surface of the printing table 2 is in a horizontal state relative to the print head. At least one of the adjustment member 3 and the printing table 2 extends into the through hole 11 and is connected to the other. The adjustment member 3 is provided with an abutting surface 311 facing the base 1, and the two ends of the biasing member 4 act on the abutting surface 311 and the base 1 respectively to abut the base 1 against the printing table 2. By applying force to the adjustment member 3, the printing table 2 connected to the adjustment member 3 is in close contact with the base 1, so that there is a damping force between the two, so that the angle will not be easily changed during the printing process. Furthermore, the adjusting member 3 is suitable for adjusting the position relative to the printing table 2 along the first direction 51 and stopping, thereby changing the distance between the abutting surface 311 and the base 1, thereby adjusting the force applied by the biasing member 4 to adjust the damping force to meet the use requirements. When leveling, the print head can be used for leveling. When the print head abuts against the center of the printing table 2, it moves relative to the printing table 2 in a horizontal direction perpendicular to the first direction 51 to push against the printing table 2, so that the printing table 2 can be universally rotated relative to the base 1, so that the surface of the printing table 2 is leveled. It can be seen that in an optional leveling method of this embodiment, the user can achieve adaptive leveling of the printing table 2 through the movement of the print head and / or the base 1 without manual leveling, thereby reducing the difficulty of leveling operation.
[0062] In an exemplary embodiment, the adjusting member 3 is suitable for being screwed to the printing table 2 to adjust the position relative to the printing table 2 and to stop, and the screwing method can realize the stepless adjustment of the damping force.
[0063] In an exemplary embodiment, the base 1 includes an arc boss 12, which is provided with a first arc surface 121 protruding toward the printing table 2; the printing table 2 is provided with an arc groove 21, which is provided with a second arc surface 211 recessed along a direction away from the base 1; the first arc surface 121 and the second arc surface 211 are offset against each other, thereby realizing universal rotation of the two. Compared with only one arc surface, the method in which both arc surfaces are provided makes the contact area between the printing table 2 and the base 1 larger, making the printing table 2 more stable.
[0064] In an exemplary embodiment, the diameter of the second arc surface 211 is greater than or equal to the diameter of the first arc surface 121, ensuring that the two can be universally rotated while the difference in printing position before and after rotation does not change too much, thereby facilitating printing operations.
[0065] In an exemplary embodiment, the printing platform 2 includes a mounting post 22, which extends into the through hole 11, and the size of the through hole 11 is larger than the size of the mounting post 22; the adjustment member 3 is connected to the mounting post 22 to achieve the connection between the two.
[0066] In an exemplary embodiment, the through hole 11 is provided with a through hole 111 and a clearance hole 112, and the through hole 111 can limit the maximum adjustment angle of the printing table 2. The clearance hole 112 is arranged on a side close to the printing table 2, and the clearance hole 112 is in a guide cone shape to prevent the through hole 11 from interfering with the mounting column 22 when the machining error of the mounting column 22 causes the chamfer between the mounting column 22 and the bottom of the circular arc groove 21 to be too large, so that the base 1 and the printing table 2 cannot achieve universal rotation or the first arc surface 121 and the second arc surface 211 cannot fit together.
[0067] In an exemplary embodiment, if the center of the printing table 2 is too far from the fulcrum to form a cantilever, when there is a printed object at the center of the printing table 2, the printing table 2 will be tilted by force, affecting the printing quality. In this embodiment, the through hole 11 is directly opposite to the center of the printing table 2, so that the base 1 can support the center of the printing table 2, reducing the possibility of the printing table 2 tilting due to the printed object.
[0068] In an exemplary embodiment, a printer includes a frame, a print head and a printing platform as described above, wherein the print head is adapted to slide relative to the frame along a first direction 51 to approach or move away from the printing platform 2, thereby achieving highly formed three-dimensional printed objects.
[0069] In an exemplary embodiment, when the print head is against the center of the printing table 2, it moves relative to the printing table 2 in a horizontal direction perpendicular to the first direction 51 to push against the printing table 2, so that the printing table 2 can rotate universally relative to the base 1, so that the surface of the printing table 2 is leveled without manual leveling, which is simple and convenient.
[0070] In an exemplary embodiment, the base 1 is connected to the frame in a horizontal sliding direction, and also drives the printing table 2 to slide, so as to realize the molding of the printed matter in at least one horizontal direction. When the print head also has the freedom of movement in the horizontal direction, the movement directions of the base 1 and the print head can be perpendicular to each other, so as to realize flat printing, and can move simultaneously to increase printing efficiency.
[0071] While in other embodiments:
[0072] The adjusting member 3 is adapted to be connected with the printing table 2 through multiple levels to adjust the position and stop relative to the printing table 2, such as the mounting column 22 is provided with multiple clamping positions arranged along the first direction 51; the adjusting member 3 is provided with a plurality of clamping parts arranged around an axis extending along the first direction 51, each clamping part is spaced apart, and each clamping part is adapted to deform in a direction close to the axis when pressed, so as to pass over the clamping position of the previous level and be connected with the clamping position of the next level. Of course, in addition to this method, other methods can also be used, such as a ratchet structure, etc.
[0073] In other embodiments, the adjusting member 3 may also be integrally formed.
[0074] In other embodiments, the print head can move horizontally relative to the frame in a manner with more degrees of freedom, such as a motion trajectory that can be a straight line, such as left-right motion and / or front-back motion and / or oblique motion, or an arc, to perform printing or leveling of the printing table 2. Of course, the print head can also achieve motion in more dimensions.
