[0022] like Figure 1As shown, a screen printing device for household appliance panels includes a frame 1, a conveyor belt 2 installed at the bottom of the frame 1, and a printing assembly on one side of the upper end of the frame 1. The printing assembly includes a squeegee mechanism and a screen mechanism, with the screen mechanism located below the squeegee mechanism. The printing assembly, consisting of the squeegee mechanism and the screen mechanism, performs printing. The squeegee mechanism includes a squeegee 4 and a return ink plate 5. A mounting frame 6 is slidably mounted on one side of the upper end of the frame 1 via a rodless cylinder. The rodless cylinder drives the mounting frame 6 to slide up and down. A slide rail 7 is mounted on one side of the mounting frame 6. A moving frame 8 is driven by a motor to slide on the slide rail 7. A moving frame 8 is slidably mounted on one side of the slide rail 7. Two sets of drive cylinders 9 are mounted on the moving frame 8. Each drive cylinder 9 has a clamp 10 mounted at its lower end. The squeegee 4 and the return ink plate 5 are clamped at the lower ends of the two sets of drive cylinders 9 via the clamps 10. The two sets of drive cylinders 9 drive the squeegee 4 and the return ink plate 5 to rise and fall for printing and inking, respectively. The wire mesh mechanism includes a wire mesh frame 11, with wire mesh installed in the middle. Fixing frames 12 are connected to both sides of the lower end of a mounting frame 6. Mounting slots are provided on opposite sides of the fixing frames 12. The wire mesh frame 11 is snapped onto the fixing frames 12 through the mounting slots. A locking mechanism is provided on the fixing frames 12 to lock the wire mesh frame 11. The locking mechanism includes a first bolt 13 threaded onto the fixing frames 12. A locking block 14 is rotatably connected to the end of the first bolt 13. The locking block 14 is slidably disposed within the mounting slot. The first bolt 13 drives the locking block 14 to move and clamp and fix the wire mesh frame 11. Engaging teeth are provided on the opposite surfaces of the locking block 14 and the wire mesh frame 11. The engagement of the engaging teeth makes the locking block 14 more stably lock the wire mesh frame 11.

[0023] A positioning mechanism is provided on the lower side of the wire mesh mechanism. The positioning mechanism positions the conveyed material. The positioning mechanism includes a guide plate 15 rotatably connected to the lower side of the wire mesh frame 11. Multiple sets of guide plates 15 are provided. The guide plates 15 are respectively set on both sides of the two ends of the wire mesh frame 11. The guide plates 15 on both sides limit and guide the material in the middle. The distance between the ends of the guide plates 15 on both sides can be adjusted by rotating the guide plates 15, which is suitable for limiting materials of different sizes. The wire mesh frame 11 can be provided with scale lines on the side, which can quickly identify the size information.

[0024] As shown in the figure, the surface of the wire mesh frame 11 is provided with an arc-shaped groove 16, and a second bolt 17 is slidably disposed in the arc-shaped groove 16. The lower end of the second bolt 17 is threadedly connected to the guide plate 15. The second bolt 17 slides in the arc-shaped groove 16 as the guide plate 15 rotates. After rotating to the correct position, the position of the guide plate 15 is locked by tightening the second bolt 17.

[0025] like Figure 3As shown, the guide plate 15 is composed of multiple telescopic plates, which are slidably fitted together in sequence. The thickness difference between the telescopic plates is small and negligible. Springs 18 connect the telescopic plates. The guide plate 15 can extend and retract with the height of the wire mesh frame 11, and the bottom of the guide plate 15 is tightly attached to the conveyor belt 2 by the action of the springs 18, reducing the gap between the guide plate 15 and the conveyor belt 2, facilitating stable material conveying and reducing the occurrence of deviation.

[0026] A cleaning brush 3 is installed on one side of the frame 1. The cleaning brush 3 cleans the conveyed material, reduces the dirt attached to the surface, and facilitates the improvement of printing quality.

[0027] During production, the panel film to be printed is released from the take-up roller and placed on the conveyor belt 2 for conveying. The panel film is conveyed between the guide plates 15 on both sides, and the printing component prints on the panel film. When printing panel films of different sizes, the guide plates 15 are rotated to adjust the distance between the ends of the guide plates 15 on both sides, thereby adapting to the size of the panel film and effectively limiting the panel film, which greatly improves the positioning accuracy.
