[0024] The present invention is described in detail below with reference to the accompanying drawings.
[0025] like Figures 1 to 2 As shown, a 3D printing device of the present invention includes a frame 1, a printing device 2 movably arranged on the frame 1, an X-axis module 3 for driving the printing device 2 to move along the X-axis direction of the frame 1, a Y-axis module 4 driven by the X-axis module 3 and used to drive the printing device 2 to move along the Y-axis direction of the frame 1, a printing platform 5 arranged below the printing device 2, and a lifting device 6 driven by the printing platform 5, wherein the lifting device 6 drives the printing platform 5 to approach or move away from the printing device 2, so that the printing platform 5 is lifted and lowered to carry the workpiece printed by the printing device 2.
[0026] During operation, the printing device 2 is driven to move along the X-axis direction of the frame 1 by the X-axis module 3, and the printing device 2 is driven to move along the Y-axis direction of the frame 1 by the Y-axis module 4, thereby realizing that the X-axis module 3 and the Y-axis module 4 jointly drive the printing device 2 to move freely in all directions, meeting the different finished product molding and manufacturing requirements in the 3D printing process. At the same time, the lifting device 6 drives the printing platform 5 to move closer to or away from the printing device 2, which helps the printing platform 5 to rise and carry the workpiece for 3D printing by the printing device 2, and helps the printing platform 5 to descend and release the finished product printed by the printing device 2. The overall structure is compact and has a high degree of coordination and cooperation. In addition, the X-axis module 3 and the Y-axis module 4 both adopt the electric module of the existing technology, and the specific shape structure and working principle are not repeated here. The utility model has a compact structure and a reasonable design, is flexible and convenient to work, has high working stability, and improves the degree of coordination and cooperation in work.
[0027] The lifting device 6 of this embodiment includes a first screw rod 61, a servo motor 62 driven by the first screw rod 61, a second screw rod 63 spaced apart from the first screw rod 61, a first screw nut 64 threadedly sleeved on the outside of the first screw rod 61, and a second screw nut 65 threadedly sleeved on the outside of the second screw rod 63. The first screw rod 61 is provided with a driving wheel 66, and the second screw rod 63 is provided with a driven wheel 67. A transmission belt 68 is connected between the driving wheel 66 and the driven wheel 67. The driven wheel 67 is connected to the second screw rod 63. A base 51 is provided at the bottom of the printing platform 5, and a buffer spring 52 is provided between the base 51 and the printing platform 5. The first screw nut 64 and the second screw nut 65 are respectively provided on both sides of the base 51. Specifically, the servo motor 62 drives the first screw rod 61 to rotate. On the one hand, the rotating first screw rod 61 drives the first screw nut 64 to move up and down. On the other hand, the rotating first screw rod 61 drives the driving wheel 66 to rotate. The rotating driving wheel 66 drives the driven wheel 67 to rotate through the transmission belt 68. The rotating driven wheel 67 drives the second screw rod 63 to rotate. The rotating second screw rod 63 drives the second screw nut 65 to move up and down synchronously. Moreover, the first screw nut 64 and the second screw nut 65 are respectively arranged on both sides of the base 51, and then the first screw nut 64 and the second screw nut 65 are used to synchronously drive the base 51 to rise and fall smoothly relative to the frame 1. Since a buffer spring 52 is arranged between the base 51 and the printing platform 5, it has a good buffering effect on the finished product, making it convenient to take and place the finished product smoothly.
[0028] In this embodiment, a first guide rod 69 and a second guide rod 610 are respectively provided on both sides of the first screw rod 61, and a first guide sleeve 611 and a second guide sleeve 612 are respectively provided on the side of the base 51 close to the first screw rod 61. The first guide sleeve 611 and the second guide sleeve 612 are respectively slidably connected to the first guide rod 69 and the second guide rod 610. A third guide rod 613 and a fourth guide rod 614 are respectively provided on both sides of the second screw rod 63, and a third guide sleeve 615 and a fourth guide sleeve 616 are respectively provided on the side of the base 51 close to the second screw rod 63. The third guide sleeve 615 and the fourth guide sleeve 616 are respectively slidably connected to the third guide rod 613 and the fourth guide rod 614. Specifically, one side of the base 51 is slidably connected to the first guide rod 69 and the second guide rod 610 through the first guide sleeve 611 and the second guide sleeve 612 respectively, and the other side of the base 51 is slidably connected to the third guide rod 613 and the fourth guide rod 614 respectively through the third guide sleeve 615 and the fourth guide sleeve 616. The force is uniform, so that the base 51 can be smoothly raised and lowered relative to the frame 1, and the guiding effect is good, which avoids the accidental falling of the finished product due to the position displacement and tilt of the base 51.
[0029] The printing device 2 of this embodiment includes a material storage box 21, a print head 22 disposed in the material storage box 21, and a Z-axis module 7 drivingly connected to the material storage box 21. The Z-axis module 7 drives the material storage box 21 toward or away from the printing platform 5, so that the print head 22 performs three-dimensional printing on the printing platform 5. Specifically, an external injection mechanism injects an appropriate amount of plastic granular material into the material storage box 21. The plastic granular material is heated and melted at a high temperature inside the material storage box 21. The Z-axis module 7 drives the material storage box 21 downward and toward the printing platform 5. The print head 22 then squeezes out the material and performs three-dimensional printing on the printing platform 5, achieving high work efficiency.
[0030] The bottom of the frame 1 of this embodiment is provided with a telescopic support leg 11 and a universal caster 12. Specifically, preferably, the telescopic support leg 11 uses an electric hydraulic telescopic rod, which can be telescoped and adjusted according to different working requirements, thereby adjusting the use height of the frame 1. The universal caster 12 facilitates the movement of the entire frame 1, thereby improving the flexibility of use.
