[0015] Compared with the prior art, the beneficial effects of this utility model are: the high-speed five-color printing machine for metal sheet printing not only realizes the automatic transport of metal sheets and the ability to limit the metal sheets to prevent them from shifting, but also realizes the automatic drying of printing materials.

[0016] (1) By setting up a conveyor belt, drive roller, support roller and drive motor, when printing, the metal sheet to be printed is placed on one side of the top of the conveyor belt, the drive motor is started to drive the drive roller to rotate, and the drive roller rotates while driving the external conveyor belt to move. The conveyor belt then automatically sends the metal sheet to the inside of the five-color printing machine for printing. The multiple sets of support rollers inside the mounting frame are attached to the bottom of the conveyor belt to support the conveyor belt and ensure the stability of the metal sheet during the conveying process, thus realizing the automatic transport of metal sheets for printing.

[0017] (2) By setting up a fixed plate, connecting plate, limiting baffle, bidirectional screw, threaded sleeve, servo motor, belt, transmission wheel and fixed cover, when printing, after the metal sheet is placed at the top of the conveyor belt, the servo motor is started to drive the bidirectional screw to rotate. At the same time, the belt and transmission wheel drive the two sets of bidirectional screws to rotate synchronously. The bidirectional screw drives the connecting plates at both ends to move to the middle through the threaded sleeves at both ends. The connecting plates then drive the limiting baffle to move. The limiting baffle can move the metal sheet to the middle position at the top of the conveyor belt. At the same time, it can limit the metal sheet by sticking to both ends of the metal sheet, preventing the metal sheet from shifting during the printing process and affecting the printing effect. This achieves effective limiting of the metal sheet.

[0018] (3) By setting up an installation plate, drying fan, dust cover, fixed frame, air inlet, dust net, electric heating tube, grid plate and electric heating box, after the metal sheet is printed, it is conveyed to the inside of the dust cover by the conveyor belt. The drying fan inside the dust cover starts to generate wind, and at the same time the electric heating tube inside the fixed frame starts to heat the air entering from the air inlet, so that the drying fan generates hot air to dry the metal sheet at the bottom, thereby accelerating the drying of the printing material. The dust net inside the air inlet can prevent dust from contaminating the printing material, thus realizing automatic drying of the printing material. Attached Figure Description

[0025] Example: Please refer to Figure 1-4 A high-speed five-color printing machine for printing on thin metal sheets includes a five-color printing machine body 1, a mounting frame 7 fixedly connected to the bottom end of the five-color printing machine body 1, the center line of the five-color printing machine body 1 and the center line of the mounting frame 7 are on the same vertical plane, a dust cover 13 is fixedly connected to one side of the top of the mounting frame 7, and a conveying mechanism for transporting thin metal sheets is provided inside the mounting frame 7.

[0026] The conveying mechanism includes a drive roller 6, drive rollers 6 are movably connected to both sides inside the mounting frame 7, a conveyor belt 5 is movably connected to the outside of the drive roller 6, a support roller 8 is movably connected inside the mounting frame 7, and a drive motor 21 is fixedly connected to one side of one end of the mounting frame 7.

[0027] The output end of the drive motor 21 passes through one end of the mounting frame 7 and is fixedly connected to the drive roller 6, while the support roller 8 is movably connected to the conveyor belt 5.

[0028] The support rollers 8 inside the mounting frame 7 are arranged at equal intervals, and the conveyor belt 5 passes through one side of the five-color machine body 1 and extends into the interior of the five-color machine body 1.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during printing, the metal sheet to be printed is placed on one side of the top of the conveyor belt 5. The drive motor 21 is started to drive the drive roller 6 to rotate. While the drive roller 6 rotates, it drives the external conveyor belt 5 to move. The conveyor belt 5 then automatically feeds the metal sheet into the interior of the five-color printing machine body 1 for printing. In addition, the multiple sets of support rollers 8 inside the mounting frame 7 are attached to the bottom of the conveyor belt 5 to support the conveyor belt 5 and ensure the stability of the metal sheet during the conveying process, thus realizing the automatic transport of the metal sheet for printing.

[0030] Mounting bracket 7 has two fixed plates 2 fixedly connected to the top two ends. One end of the fixed plate 2 is movably connected to a bidirectional lead screw 9. The two ends of the bidirectional lead screw 9 are movably connected to threaded sleeves 10. One end of the threaded sleeve 10 is fixedly connected to a connecting plate 3. The bottom end of the connecting plate 3 is fixedly connected to a limit baffle 4. The other end of the fixed plate 2 is fixedly connected to a fixed cover 24. The bidirectional lead screw 9 passes through the fixed plate 2 and extends into the interior of the fixed cover 24, where a transmission wheel 23 is fixedly connected. The outside of the transmission wheel 23 is movably connected to a belt 22. The other end of the fixed plate 2 is fixedly connected to a servo motor 20.

[0031] The output end of the servo motor 20 passes through the fixed plate 2 and is fixedly connected to the bidirectional lead screw 9. The center line of the transmission wheel 23 and the center line of the bidirectional lead screw 9 are on the same horizontal plane.

[0032] The threaded sleeves 10 at both ends of the double-ended lead screw 9 are arranged symmetrically, and the fixing plate 2 is fixedly connected to the main body 1 of the five-color machine;

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during printing, after the metal sheet is placed at the top of the conveyor belt 5, the servo motor 20 is started to drive the bidirectional lead screw 9 to rotate. At the same time, the belt 22 and the transmission wheel 23 drive the two sets of bidirectional lead screws 9 to rotate synchronously. The bidirectional lead screw 9 drives the connecting plates 3 at both ends to move towards the middle through the threaded sleeves 10 at both ends. The connecting plates 3 then drive the limiting baffles 4 to move. The limiting baffles 4 can move the metal sheet to the middle position at the top of the conveyor belt 5.

A fixing frame 14 is fixedly connected to the top of the dust cover 13. Electric heating boxes 19 are fixedly connected to both sides inside the fixing frame 14. An electric heating tube 17 is fixedly connected to one side of the electric heating box 19. A mesh plate 18 is fixedly connected to the bottom of the fixing frame 14. An air inlet 15 is fixedly connected to the top of the dust cover 13. A dustproof net 16 is fixedly connected to the inside of the air inlet 15.

[0035] The air inlet 15 is connected to the interior of the dust cover 13, and the center line of the drying fan 12 is on the same vertical plane as the center line of the mounting bracket 7.

[0036] Specifically, such as Figure 1As shown, after the metal sheet is printed, it is conveyed by the conveyor belt 5 to the inside of the dust cover 13. The drying fan 12 inside the dust cover 13 starts to generate airflow. At the same time, the electric heating tube 17 inside the fixed frame 14 starts to heat the air entering from the air inlet 15, so that the drying fan 12 generates hot air to dry the metal sheet at the bottom, thereby accelerating the drying of the printing material. The dustproof net 16 inside the air inlet 15 can prevent dust from contaminating the printing material, thus realizing automatic drying of the printing material.

[0037] Working Principle: In use, during printing, the metal sheet to be printed is placed on one side of the top of the conveyor belt 5. The drive motor 21 is started, driving the drive roller 6 to rotate. Simultaneously, the drive roller 6 rotates, causing the external conveyor belt 5 to move. The conveyor belt 5 then automatically feeds the metal sheet into the main body 1 of the five-color printing machine for printing. Multiple sets of support rollers 8 inside the mounting frame 7 are attached to the bottom of the conveyor belt 5 to support it, ensuring the stability of the metal sheet during transport. During printing, after the metal sheet is placed at the top of the conveyor belt 5, the servo motor 20 is started, driving the bidirectional lead screw 9 to rotate. Simultaneously, the belt 22 and transmission wheel 23 drive two sets of bidirectional lead screws 9 to rotate synchronously. The bidirectional lead screws 9 are connected to the external... The threaded sleeves 10 at both ends drive the connecting plates 3 at both ends to move towards the middle. The connecting plates 3 then drive the limiting baffles 4 to move. The limiting baffles 4 can move the metal sheet to the middle position at the top of the conveyor belt 5. At the same time, they can be attached to both ends of the metal sheet to limit it and prevent the metal sheet from shifting during the printing process and affecting the printing effect. After the metal sheet is printed, it is sent to the inside of the dust cover 13 by the conveyor belt 5. The drying fan 12 inside the dust cover 13 starts to generate air. At the same time, the electric heating tube 17 inside the fixed frame 14 starts to heat the air entering from the air inlet 15, so that the drying fan 12 generates hot air to dry the metal sheet at the bottom, thereby accelerating the drying of the printing material. The dustproof net 16 inside the air inlet 15 can prevent dust from contaminating the printing material.
