[0025] Example 1: As Figures 1-3 The present invention provides the following technical solution: a 3D printing advertising letter curing extrusion mechanism, comprising: a magnetic suction sheet 5, nested on the upper surface of a movable base 2, with a dustproof component 6 magnetically connected to the upper side of the magnetic suction sheet 5, and a flexible sheet 7 installed in the middle section of the inner surface of the dustproof component 6, through which the printing material 3 passes; and the movable base 2 is provided with an extrusion conveying mechanism; the movable base 2 forms a magnetic suction structure with the magnetic suction sheet 5 and the dustproof component 6, and the dustproof component 6 forms a through-structure with the printing material 3 through the flexible sheet 7.

[0026] In use, the position of the print head 4 is controlled by the movable base 2 assembled by the printer bracket 1. The position of the print head 4 can be controlled according to the shape of the advertising lettering to form the melted printing material 3 layer by layer. The dustproof component 6 is installed with the flexible sheet 7 nested on the outside of the printing material 3. The dustproof component 6 is positioned on the upper surface of the movable base 2 with the magnetic suction piece 5. The dustproof performance of the movable base 2 in conveying the printing material 3 can be controlled. When the print head 4 is working, the heating component 9 with heat dissipation fins 8 can be used to effectively melt the printing material 3.

[0027] Example 2: Figures 1-4The technical solution shown, based on Embodiment 1, further discloses a stable delivery of printing material 3 by the movable seat 2, the specific details of which are as follows: A print head 4 is installed on the lower side of the inner surface of the movable seat 2, and a heating element 9 is connected to the outer surface of the print head 4. A heat dissipation fin 8 is installed on the outer surface of the heating element 9. A side plate 17 is installed on the outer surface of the movable seat 2, and the side plate 17 is equipped with an angle adjustment mechanism. The extrusion delivery mechanism includes a threaded rod 10 rotatably connected to the inner surface of the movable seat 2, and a movable element 11 is threadedly connected to the outer surface of the threaded rod 10. A limiting strip 12 is installed on the outer surface of the movable element 11, and a slider 13 is slidably connected to the outer surface of the limiting strip 12, limiting the slider 13 to slide within the movable seat 2. A compression spring 14 is elastically connected between the slider 13 and the moving part 11, and a support frame 15 is installed on the outer surface of the slider 13. At the same time, a compression roller 16 is rotatably connected to the inner surface of the support frame 15, and the compression roller 16 is limited and squeezed onto the outer surface of the printing material 3. The moving seat 2 forms a threaded structure with the moving part 11 through the threaded rod 10, and the moving part 11 forms an elastic limiting sliding structure with the slider 13 through the limiting strip 12 and the compression spring 14.

[0028] In use, a small synchronous motor assembled on the outside of the movable base 2 controls the threaded rod 10 with a bidirectional thread structure to control the moving part 11 for centering adjustment. When the moving part 11 moves, it cooperates with the externally nested compression spring 14 to control the support frame 15 mounted on the slider 13 to slide elastically. After the compression roller 16 assembled on the support frame 15 contacts the printing material 3, the moving part 11 can be controlled to move continuously for a certain distance and then stop centering and conveying.

The moving base 2 and the side plate 17 form an integrated structure. A base plate 18 is rotatably connected to the lower outer surface of the side plate 17, and a moving block 19 is threadedly connected to the inside of the side plate 17. A diagonal brace 20 is rotatably connected to the outer surface of the moving block 19, and the lower surface of the diagonal brace 20 is rotatably connected to the base plate 18. A curing fan 21 is nestedly connected to the inner surface of the base plate 18. The side plate 17 and the base plate 18 form a positioning and rotating structure, and the side plate 17 forms a deflection structure with the base plate 18 through the moving block 19 and the diagonal brace 20. The base plate 18 and the curing fan 21 form a nested structure.

[0030] When the print head 4 is forming the advertising text, the curing fan 21 nested in the side plate 17 installed on the outside of the movable seat 2 and the bottom plate 18 that rotates at the bottom of the outer surface of the side plate 17 accelerates the curing of the material. In conjunction with the motor installed on the top of the side plate 17, the movable block 19 can be driven to slide and adjust by thread, and the inclined support 20 connected to the movable block 19 can be controlled to adjust the angle of the bottom plate 18 on the side plate 17, thereby controlling the angle of the curing fan 21. The angle of the curing fan 21 can be controlled according to the printing time and the printing position of the advertising text to improve the curing efficiency.
