Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a 3D printer platform adjustment mechanism and method thereof. Background Art

[0002] A 3D printer is a device that creates three-dimensional objects by adding materials layer by layer. To achieve some complex printing requirements, the 3D printer platform adjustment mechanism can adjust the printing platform angle to achieve high-quality print output. It mainly includes a platform support frame, a cooling system, a rotating device, and a connecting bracket. The platform support frame is the overall framework that supports and fixes the printing platform, and is used to ensure the stability of the overall structure. The cooling system not only prevents material deformation caused by thermal stress, but also helps to quickly cool it down, ensuring good adhesion between layers and avoiding printing failure or delamination. The rotating device can adjust the angle of the printing platform to meet complex printing requirements. The connecting bracket is used to connect the printing platform to the adjustment mechanism. When adjusting the angle of the existing 3D printer platform adjustment mechanism, when one side descends, the platform height cannot be adjusted synchronously, resulting in a lower position on the descending side, which in turn increases the gap between the nozzle and the platform. At the same time, the cooling rate cannot be changed according to the angle of the platform. When the platform angle is tilted, the printing material will be unevenly stressed and unable to be cooled quickly, which will affect the printing quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a 3D printer platform adjustment mechanism and method thereof to solve the following technical problems: the 3D printer platform adjustment mechanism cannot synchronously adjust the platform height and cooling rate when adjusting the angle, resulting in a large gap between the nozzle and the platform. When tilting, the printing material is unevenly subjected to force and cannot be quickly cooled, which affects its printing quality.

[0013] A 3D printer platform adjustment method, comprising: Step 1: The electric telescopic rod can drive the moving plate to move, and the movement of the moving plate drives the top plate to rotate through the cooperation of the rotating plate. When the electric telescopic rod pushes the moving plate to drive the teeth to move, the teeth cannot drive the threaded rod 2 to rotate through the spur gear 1. At this time, one side of the top plate rises, and there is no problem of a large gap between the top plate and the nozzle, and there is no need to adjust the height of the top plate; Step 2: When the electric telescopic rod pulls the movable plate, the movable plate moves through the rotating plate to drive one side of the top plate to descend. After one side of the top plate descends, the gap between the print head and the top plate becomes larger, thereby affecting the printing quality. At this time, the movement of the movable plate can drive the teeth to move, and the movement of the teeth drives the spur gear 1 to rotate. The rotation of the spur gear 1 drives the threaded rod 2 to rotate. The rotation of the threaded rod 2 can make the lifting plate rise. The lifting plate can drive the top plate to rise, thereby reducing the gap between the print head and the top plate and improving the processing quality. Step 3: Start the second motor to drive the driving shaft to rotate. The rotation of the driving shaft drives the active helical gear set to rotate, and then the helical gear drives the first shaft to rotate. The rotation of the first shaft drives the belt pulley to rotate. The rotation of the belt pulley drives the second shaft to rotate. The rotation of the second shaft drives the rotating blades to rotate. The rotation of the rotating blades can draw external air into the bottom plate and flow into the top plate through the lifting plate, thereby cooling the top plate. This not only prevents the top plate from deforming the material due to heat, but also helps the product cool down quickly, ensuring good adhesion between the layers and avoiding printing failure or delamination. Step 4. When the electric telescopic rod drives the moving plate to move and the top plate rotates, the top plate presents an inclined surface, which causes uneven force on the printing material. When the moving plate moves, it can drive the connecting block to move, and the movement of the connecting block drives the rack plate to move. Through the cooperation of the two rack plates and the spur gear 2, no matter which direction the moving plate drives the connecting block to move, it can push the push plate to move. The push plate moves and drives the fixed plate to move through the connecting plate, and then drives the active helical gear set to move, so that the active helical gear set is disengaged from the helical gear 1 and engages with the helical gear 2. At this time, the speed of the rotating shaft 1 can be increased, thereby increasing the speed of the rotating blade, increasing the cooling rate, and ensuring that the printing material is cooled quickly.

[0014] Beneficial effects of the present invention: (1) The present invention drives the moving plate to move through the electric telescopic rod, and the movement of the moving plate drives the top plate to rotate through the rotating plate. After the top plate rotates, it can meet complex printing requirements. When the electric telescopic rod pulls the moving plate to move so that one side of the top plate descends and rotates, the movement of the moving plate can make the lifting plate rise through the cooperation of the teeth, the spur gear one and the threaded rod two. The lifting plate drives the top plate to rise, thereby reducing the gap between the top plate and the nozzle, preventing the problem of excessive gap between the nozzle and the top plate during the printing process, and thus improving the printing quality.

[0015] (2) In the present invention, when the moving plate moves to cause the top plate to rotate, the movement of the moving plate drives the connecting block to move, and the movement of the connecting block drives the rack plate to move. Through the cooperation of the two rack plates and the spur gear 2, no matter which direction the moving plate drives the connecting block to move, the push plate can be pushed to move. The movement of the push plate can drive the active helical gear set to move through the connecting plate and the fixed plate, so that the active helical gear set is released from engagement with the helical gear 1 and engages with the helical gear 2, thereby increasing the rotation speed of the rotating blade, increasing the cooling rate, and ensuring that the printing material is quickly cooled.

[0016] (3) The present invention starts the second motor to drive the driving shaft to rotate, and the rotation of the driving shaft drives the active helical gear set to rotate, and then drives the rotating blades to rotate through the cooperation of the helical gear one, the first rotating shaft, the belt pulley and the second rotating shaft. The rotation of the rotating blades can draw external air into the interior of the bottom plate and flow into the interior of the top plate through the lifting plate, thereby cooling the top plate. This can not only prevent the top plate from deforming due to heat, but also help the product cool down quickly, ensure good adhesion between the layers, and avoid printing failure or delamination.

The movement of the movable plate 33 drives the top plate 31 to rotate through the cooperation of the rotating plate 32. When the electric telescopic rod 34 pushes the movable plate 33 to drive the teeth 24 to move, the movement of the teeth 24 cannot drive the threaded rod 2 22 to rotate through the spur gear 1 23.

Starting the electric telescopic rod 34 can drive the movable plate 33 to move, and the movement of the movable plate 33 drives the rotating plate 32 to rotate, and the rotating plate 32 drives the top plate 31 to rotate. When the electric telescopic rod 34 pushes the movable plate 33, one side of the top plate 31 rises. When the electric telescopic rod 34 pulls the movable plate 33 to move, one side of the top plate 31 falls. The top plate 31 When one side of the nozzle falls, the gap between the nozzle and the top plate 31 becomes larger, thereby affecting the printing quality. At this time, the movement of the movable plate 33 can drive the teeth 24 to move, and the movement of the teeth 24 drives the spur gear 1 23 to rotate. The rotation of the spur gear 1 23 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 can make the lifting plate 21 rise.

The movement of the active helical gear set 47 can release the engagement between the active helical gear set 47 and the helical gear 1 51, so that the active helical gear set 47 is engaged with the helical gear 2 52, thereby increasing the rotation speed of the rotating blade 55. When the top plate 31 is in an inclined state, the cooling rate can be increased to ensure that the printing material is cooled quickly.

10. A 3D printer platform adjustment method using the 3D printer platform adjustment mechanism of claim 9, characterized in that: include: Step 1: The electric telescopic rod (34) can drive the movable plate (33) to move, and the movement of the movable plate (33) drives the top plate (31) to rotate through the cooperation of the rotating plate (32). When the electric telescopic rod (34) pushes the movable plate (33) to drive the teeth (24) to move, the movement of the teeth (24) cannot drive the threaded rod (22) to rotate through the spur gear (23). At this time, one side of the top plate (31) rises, and there is no problem of a large gap between the top plate (31) and the nozzle, and there is no need to adjust the height of the top plate (31); Step 2: When the electric telescopic rod (34) pulls the movable plate (33), the movable plate (33) moves through the rotating plate (32) to drive one side of the top plate (31) to descend. After one side of the top plate (31) descends, the gap between the nozzle and the top plate (31) becomes larger, thereby affecting the printing quality. At this time, the movement of the movable plate (33) can drive the teeth (24) to move, and the movement of the teeth (24) drives the spur gear 1 (23) to rotate. The rotation of the spur gear 1 (23) drives the threaded rod 2 (22) to rotate. The rotation of the threaded rod 2 (22) can make the lifting plate (21) rise. The lifting of the lifting plate (21) can drive the top plate (31) to rise, thereby reducing the gap between the nozzle and the top plate (31) and improving the processing quality. Step 3: Start the second motor (49) to drive the driving shaft (48) to rotate. The rotation of the driving shaft (48) drives the active helical gear set (47) to rotate, and then drives the rotating shaft (50) to rotate through the helical gear (51). The rotating shaft (50) rotates and drives the belt pulley (53) to rotate. The belt pulley (53) rotates and drives the second rotating shaft (54). The rotating shaft (54) rotates and drives the rotating blade (55). The rotating blade (55) rotates and draws the external air into the interior of the bottom plate (11) and flows into the interior of the top plate (31) through the lifting plate (21), thereby cooling the top plate (31). This not only prevents the deformation of the material of the top plate (31) due to heat, but also helps the product to cool quickly, ensuring good adhesion between the layers and avoiding printing failure or delamination. Step 4: When the electric telescopic rod (34) drives the moving plate (33) to move so that the top plate (31) rotates, the top plate (31) presents an inclined surface, thereby causing uneven force on the printing material. When the moving plate (33) moves, it can drive the connecting block (41) to move. The movement of the connecting block (41) drives the rack plate (42) to move. Through the cooperation of the two rack plates (42) and the spur gear 2 (43), no matter which direction the moving plate (33) drives the connecting block (41) to move, it can push the push plate (44) to move. The push plate (44) moves through the connecting plate (45) to drive the fixed plate (46) to move, and then drives the active helical gear set (47) to move, so that the active helical gear set (47) releases the meshing with the helical gear 1 (51) and meshes with the helical gear 2 (52). At this time, the rotation speed of the rotating shaft 1 (50) can be increased, thereby increasing the rotation speed of the rotating blade (55), increasing the cooling rate, and ensuring that the printing material is quickly cooled.
