[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0028] Please refer to Figure 1 , Figure 5 and Figure 6 , a silk screen printing machine for making greeting card graphics: including a mounting frame 1, a servo motor 2 is fixedly connected to one side of the mounting frame 1, the output end of the servo motor 2 is fixedly connected to a gear assembly 3, the gear assembly 3 is meshed with a gear shaft 4, both ends of the gear shaft 4 are meshed with a gear threaded rod 5, a connecting block 6 is threadedly connected to the surface of the gear threaded rod 5, an electric telescopic rod 7 is fixedly connected to the bottom of the connecting block 6, a scraping plate 8 is fixedly connected to the bottom end of the electric telescopic rod 7, connecting rods 9 are fixedly connected to the four circumferences at the bottom of the mounting frame 1, and a printing frame 10 is fixedly connected to the bottom end of the connecting rod 9;

[0029] The feeding mechanism includes a storage box 11 fixedly connected to the top of the connecting block 6, a transport pipe 12 is fixedly connected to one side of the storage box 11, a telescopic rod 13 is fixedly connected to the bottom of the transport pipe 12, a push rod 14 is fixedly connected to the middle of the inner wall of the telescopic rod 13, a push plate 15 is fixedly connected to the bottom end of the push rod 14, and the bottom end of the telescopic rod 13 is fixedly connected to the top of the scraping plate 8.

[0030] When using a screen printing machine for making greeting card graphics, first add the dye into the storage box 11, then place the greeting card on the top of the workbench 17, then power on the servo motor 2. The output end of the servo motor 2 drives the gear assembly 3 to rotate. The rotation of the gear assembly 3 drives the gear shaft 4 to rotate through meshing. The rotation of the gear shaft 4 drives the gear threaded rod 5 to rotate through meshing. The rotation of the gear threaded rod 5 drives the connecting block 6 on its surface to move. Then, the electric telescopic rod 7 drives the squeegee 8 to descend, so that the bottom of the squeegee 8 fits against the top of the printing frame 10. The movement of the connecting block 6 drives the electric telescopic rod 7 at the bottom to move. The movement of the electric telescopic rod 7 drives the squeegee 8 at the bottom end to move. The dye on the top of the printing frame 10 is scraped to the middle of the top of the printing frame 10 through the movement of the squeegee 8, so that the dye penetrates through the printing frame 10 to print the greeting card. Then, the electric telescopic rod 7 drives the squeegee 8 to rise. The rising of the squeegee 8 drives the telescopic rod 13 at the top to rise. The rising of the telescopic rod 13 is squeezed by the conveying pipe 12, so that the telescopic rod 13 contracts. The contraction of the telescopic rod 13 enables the push rod 14 to push the push plate 15 to the bottom of the telescopic rod 13, thereby pushing the dye in the telescopic rod 13 to the bottom of the telescopic rod 13 and then pushing the dye at the bottom of the telescopic rod 13 into the squeegee 8. Finally, it is discharged from the bottom of the squeegee 8 and drips onto the top of the printing frame 10, thus completing the addition of the dye.

[0031] Please refer to Figure 2 and Figure 3 , at the four-week of the bottom of the installation frame 1 are fixedly connected with hydraulic cylinders 16. The bottom ends of the hydraulic cylinders 16 are fixedly connected with a workbench 17. In the middle of the top of the workbench 17 is provided with a placement groove 26. At the four-week of the bottom of the workbench 17 are fixedly connected with support frames 18. One side of the support frame 18 is fixedly connected with a reinforcing rod 19.

[0032] When printing, first place the greeting card on the top of the placement groove 26, and then drive the installation frame 1 to descend through the hydraulic cylinder 16. The descent of the installation frame 1 drives the connecting rod 9 at the bottom to descend. The descent of the connecting rod 9 drives the printing frame 10 at the bottom end to descend, so that the printing frame 10 descends into the placement groove 26, and the bottom of the printing frame 10 fixes the greeting card in the placement groove 26.

[0033] Please refer to Figure 3 , Figure 4 and Figure 7 , one side of the installation frame 1 is fixedly connected with a protective box 20, and the inner wall of the protective box 20 abuts against the surface of the servo motor 2. On the top of the storage box 11 is provided with a feed inlet 21. The inner wall of the feed inlet 21 is threadedly connected with a box cover 22.

[0034] The protective box 20 can protect the servo motor 2. When adding dye, first turn the box cover 22 to open the feed port 21, then inject the dye into the storage box 11, and then fix it to the feed port 21 by turning the box cover 22.

[0035] Please refer to Figure 3 , Figure 6 and Figure 8 As shown in, the middle parts around the push plate 15 are fixedly connected with a sealing ring 23, and the surface of the sealing ring 23 abuts against the inner wall of the telescopic rod 13. A printing groove 24 is formed in the middle of the printing frame 10, and the bottom of the squeegee 8 abuts against the top of the printing frame 10. The cross section of the squeegee 8 is an isosceles trapezoid, and a conveying groove 25 is formed in the inner wall of the squeegee 8.

[0036] When the push plate 15 descends while fitting inside the telescopic rod 13, the sealing ring 23 enables the push plate 15 to better fit against the inner wall of the telescopic rod 13. When the squeegee 8 moves, the dye can pass through the printing groove 24 and adhere to the surface of the greeting card. When supplying the dye, the dye inside the telescopic rod 13 can drip onto the top of the printing frame 10 through the conveying groove 25.

[0037] Working principle: When using a silk screen printing machine for making greeting card graphics, first inject the dye into the storage box 11, then place the greeting card on the top of the placement groove 26, and then drive the mounting frame 1 to descend through the hydraulic cylinder 16, so that the bottom of the printing frame 10 moves into the placement groove 26 to clamp and fix the greeting card. Then drive the squeegee 8 to fit against the top of the printing frame 10 through the electric telescopic rod 7, and drive the squeegee 8 to move through the servo motor 2, thereby driving the squeegee 8 to push the dye on the top of the printing frame 10 into the printing groove 24, so that the dye passes through the printing groove 24 and adheres to the top of the greeting card, thus completing the printing of the greeting card.
