The top of the platform guard plate 13 and the platform support plate 14 are provided with multiple evenly arranged small holes. The air nozzle fixing block 12 of the platform guard plate 13 is connected to the platform air nozzle 25 through the air pipe 11. The platform air nozzle 25 is fixedly connected to the sliding plate 9. The sealing cavity 23 of the platform guard plate and the sealing cavity 24 of the platform support plate are connected to the vacuum pump 1 28 and the vacuum pump 29 through the upper tee 26 and the lower tee 27, respectively. The cylinder 22 is connected to the lifting swing plate 8 through the cylinder support frame 20 and the cylinder swing ring 21, and is used to drive the lifting swing plate 8 to swing up and down.

[0031] Platform tray 14 serves to support the printing plate and provides a basic structure for mounting other components. A platform guard plate 13 is connected to one side of platform tray 14 to support the printing plate. Air nozzle fixing blocks 12 are fixedly connected to both sides of the top of platform guard plate 13 to install and secure air nozzles for a stable air path connection. Platform tray sealing cavities 24 and platform air nozzles 25 are fixedly connected to both sides of the bottom of platform tray 14 to form a sealed space for use with a vacuum adsorption system.

[0032] The platform tray 14 is equipped with a drive mechanism and a lifting mechanism on its top. The drive mechanism includes a motor 1 and a lifting swing plate 8, whereby the motor 1 is fixed to the lifting swing plate 8 to provide power for the platform's movement. The lifting swing plate 8 is located on top of the platform tray 14, serving to support and adjust the lifting position. A reducer 2 is fixedly connected to the output end of the motor 1 to reduce the motor's speed and increase its torque. A gear 4 is fixedly connected to one output end of the reducer 2, enabling linear movement of the platform tray through gear transmission. A coupling 16 is fixedly connected to the other output end of the reducer 2 to connect a drive shaft for power transmission. The drive shaft drives the gear 4 on the other side, causing synchronous movement.

[0033] The platform support plate 14 has lifting swing plates 8 on both sides of its top. The lifting swing plates 8 are linearly connected to linear guide rails 10 to guide the linear movement of the sliding assembly. A sliding plate 9 is fixedly connected to the linear guide rails 10, providing smooth sliding support. A rack 5 is fixedly connected to the top of the sliding plate 9, meshing with a gear 4, which drives the sliding plate 9 to move. Limit bearings 7 are fixedly connected to the platform support plate 14 and located on both sides of the sliding plate 9 to limit the lifting range of the sliding plate 9 and prevent excessive displacement.

[0034] The lifting mechanism includes a cylinder 22 and a rotating shaft 15. The cylinder 22 provides lifting power. The top of the cylinder support frame 20 is bolted to the bottom of the platform plate 14 to support the cylinder swing ring 21. One end of the cylinder 22 is fixed to the cylinder swing ring 21 to secure the cylinder 22. The cylinder swing ring 21 is hinged to the lower part of the cylinder support frame 20 to allow for the swing adjustment of the cylinder 22. The output end of the cylinder 22 is hinged to the bottom of the lifting swing plate 8, and the platform guard plate 13 is raised and lowered through the extension and retraction of the cylinder 22. A fixing sleeve 18 is fixedly connected to the rear of the platform plate 14 to support the rotating mechanism. An oil-free bushing 19 is installed inside the fixing sleeve 18 to reduce friction and improve the lifespan of the rotating shaft 15. The rotating shaft 15 is located inside the oil-free bushing 19, and the rotating shaft 15 is fixedly connected to the two lifting swing plates 8 via a tightening sleeve 17 to achieve synchronous lifting on both sides.

[0035] A vacuum pump 28 is placed at the bottom of the platform tray 14 to provide negative pressure for adsorbing the printing plate. The input end of the vacuum pump 28 is fixedly connected to an upper tee 26 via an air pipe 11, which distributes the vacuum pressure to multiple adsorption points. An air pipe 11 is fixedly connected to the outside of the upper tee 26, connecting to the platform air nozzle 25, which connects to the platform tray sealing cavity 24 and forms negative pressure adsorption. Multiple evenly arranged small holes are opened at the top of the platform tray 14 to make vacuum adsorption more uniform.

[0036] Another vacuum pump 29 is placed under the platform tray 14 to provide negative pressure for adsorbing the printing plate. The input end of the vacuum pump 29 is fixedly connected to a solenoid valve 30. The solenoid valve 30 is fixedly connected to a lower tee 27 through an air pipe 11 to distribute the vacuum pressure to multiple adsorption points. An air pipe 11 is fixedly connected to the outside of the lower tee 27. The other end of the air pipe 11 is fixedly connected to the outside of the sealing cavity 23 of the platform guard plate, so that the sealing cavity 23 of the platform guard plate forms a negative pressure adsorption. The top of the platform guard plate 13 has multiple evenly arranged small holes, which makes the vacuum adsorption more uniform.

[0037] The limiting plate 6 is fixedly connected to the limiting bearing 7 to limit the sliding plate 9, thereby restricting the lifting range of the sliding plate 9 and preventing excessive displacement. The linear guide rail 10 is linearly connected to the lifting swing plate 8 to ensure smooth sliding of the platform mechanism. The reducer 2 is fixedly connected to the top of the platform support plate 14 via the connecting plate 3, providing stable installation support.

[0038] Working principle: When the operator cuts the printing plate and double-sided tape, the cylinder 22 in the lifting mechanism drives the lifting swing plate 8 to rise and fall through the cylinder support frame 20 and the cylinder swing ring 21, ensuring that the platform guard plate 13 can reach the correct working height. The rotating shaft 15 is fixedly connected to the lifting swing plates 8 on both sides through the expansion sleeve 17 to ensure that the lifting of the platform guard plate 13 on both sides is consistent. During this process, the limit bearing 7 between the limit plate 6 and the sliding plate 9 plays a supporting and limiting role, preventing the platform guard plate 13 from rising excessively. The motor 1 starts to work, driving the reducer 2, which meshes with the rack 5 through the gear 4, so that the platform guard plate 13 moves backward along the linear guide rail 10, making room for the movement of the cutter.

[0039] When the operator initiates the plate mounting process, the platform guard plate 13 retracts to the vicinity of the platform tray, places the printing plate, and the vacuum pump 28 starts, drawing air into the platform tray sealing cavity 24 through the upper tee 26 and air pipe 11 to create negative pressure. This negative pressure is evenly distributed through multiple small holes at the top of the platform tray 14, adsorbing and firmly fixing the printing plate to the platform tray 14. During the adsorption process, the platform air nozzle 25 cooperates with the platform tray sealing cavity 24 to further enhance the adsorption effect, ensuring the printing plate remains stable and does not slip.

[0040] Vacuum pump 29 starts simultaneously, drawing air into the sealing cavity 23 of the platform guard plate through the lower tee 27 and the air pipe 11, creating a negative pressure. The negative pressure is evenly distributed through multiple small holes at the top of the platform guard plate 13, adsorbing the printing plate and making it firmly adhered to the platform guard plate.

[0041] The platform locates the printing plate using visual inspection. Vacuum pump 29 stops, solenoid valve 30 cuts off the air supply, and motor 1 starts working, driving reducer 2. Through gear 4 and rack 5, the platform guard plate 13 moves outward along linear guide rail 10, providing space for the printing roller to rise. Motor 1 reduces its speed and increases its torque through reducer 2, ensuring the platform can move smoothly and accurately to the required position. After the printing roller approaches the printing plate, the pressure roller presses down, achieving automatic plate application. The plate application operation is completed under precise control. This completes the workflow of the automatic plate application platform of the plate-mounting machine. The entire process is efficient and automated, ensuring accurate plate installation and stable operation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
