[0002] Gravure printing grinding is an important link in the gravure printing process, mainly involving the grinding and trimming of gravure printing cylinders, scraping knives and other related components to ensure printing quality and efficiency. When the existing intaglio printing plate cylinders are subjected to grinding processing, clamping devices are usually used to move and transport the intaglio printing plate cylinders. During the moving and transporting process, the outer surface of the intaglio printing plate cylinder is likely to be damaged due to rigid clamping. Moreover, when transporting intaglio printing plate cylinders of different sizes, due to the inadaptability of the equipment, accessories are often replaced to ensure transportation stability, which reduces the processing efficiency of the printing plate cylinders. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an upper plate driving device for a grinding machine for an intaglio printing plate cylinder, which is used to solve the problems existing in the background art.

[0026] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0027] As Figure 1-2 shown, a plate loading driving device for a gravure printing plate cylinder grinding machine of the present utility model includes a conveyor belt 1 and a gravure printing plate cylinder 11. A cross plate 24 is fixedly assembled on the front side of the conveyor belt 1. Support shafts 12 are fixedly assembled on both the left and right sides of the gravure printing plate cylinder 11. The support shaft 12 is a component for installing and supporting the gravure printing plate cylinder 11. A ceiling electric slide rail 13 is assembled above the conveyor belt 1. L-shaped ceiling brackets 16 are fixedly provided on both the front and rear sides of the ceiling electric slide rail 13. The ceiling electric slide rail 13 can be fixed on the top frame of the device through the L-shaped ceiling bracket 16. A corner brace 161 is fixedly assembled at the corner of the L-shaped ceiling bracket 16. The corner brace 161 can improve the support strength of the L-shaped ceiling bracket 16. A cross bar 14 is fixedly assembled at the moving end of the ceiling electric slide rail 13. By starting the ceiling electric slide rail 13, the cross bar 14 can be driven to move back and forth. A driving structure is fixedly assembled at the lower end of the cross bar 14;

[0028] As Figure 1 、 3, as shown in Figure 4, the driving structure includes a lifting cylinder 15. The lower output end of the lifting cylinder 15 is fixedly assembled with an assembly frame 151. By starting the lifting cylinder 15, the assembly frame 151 can be driven to move up and down. The upper end of the assembly frame 151 is fixedly assembled with a driving motor 152. A rotating rod is rotatably assembled in the middle of the assembly frame 151. The driving motor 152 is in transmission connection with the rotating rod. By relying on the transmission of the driving motor 152, the rotating rod rotates inside the assembly frame 151. Both the left and right ends of the rotating rod rotatably penetrate the assembly frame 151 and are fixedly connected with gears 153. During the rotation of the rotating rod, the gears 153 can be driven to rotate simultaneously. Both the left and right sides of the assembly frame 151 are fixedly assembled with telescopic cylinders 154 and insertion frames 155. A rack 156 is slidably assembled up and down inside the telescopic cylinder 154. The rack 156 meshes with the gear 153. A diagonal rod 157 is fixedly provided at the lower end of the rack 156. The rotation of the gear 153 can drive the rack 156 and the diagonal rod 157 to move up and down. Rubber gaskets 17 are fixedly provided on one side of the insertion frame 155 close to the diagonal rod 157 and on the upper side of the diagonal rod 157. A slot 158 matching the diagonal rod 157 is opened at the lower end of the insertion frame 155. By the fit of the insertion frame 155 and the diagonal rod 157, a V-shaped opening can be constructed for loading the support shaft 12;

[0029] As Figure 5 shown, baffles 21 are fixedly provided on both the left and right sides of the conveyor belt 1. Notch openings 22 are opened at the opposite ends of the two baffles 21. A number of evenly distributed rotating wheels 23 are rotatably assembled in the notch openings 22. The number of rotating wheels 23 can drive the gravure cylinder 11, avoiding contact damage between the side of the gravure cylinder 11 and the conveyor belt 1. The sides of the number of rotating wheels 23 protrude from the notch openings 22, and the number of rotating wheels 23 are all rubber rollers;

[0030] When using this device to move the gravure printing plate cylinder 11, the gravure printing plate cylinder 11 is centrally conveyed through the conveyor belt 1. After the gravure printing plate cylinder 11 is conveyed to the front end, it will lean against the cross plate 24, and the conveyor belt 1 stops moving until the device transports the gravure printing plate cylinder 11 on the front side. The ceiling electric slide rail 13 drives the cross bar 14 to move back and forth, and the lifting cylinder 15 drives the assembly frame 151 to move up and down. At this time, the drive motor 152 starts to drive the rack 156 and the inclined rod 157 to move downward, so that the inclined rod 157 disengages from the slot 158. The position of the insertion frame 155 can be quickly adjusted through the ceiling electric slide rail 13 and the lifting cylinder 15, so that the support shaft 12 is located between the insertion frame 155 and the rack 156. At this time, the drive motor 152 starts again, driving the rack 156 and the inclined rod 157 to move upward, so that the inclined rod 157 and the insertion frame 155 can frame the support shaft 12. At this time, the assembly frame 151 can be driven to move through the ceiling electric slide rail 13 and the lifting cylinder 15. The two sides of the assembly frame 151 can frame the support shaft 12 of the gravure printing plate cylinder 11 to lift the gravure printing plate cylinder 11, thus realizing the handling of the gravure printing plate cylinder 11. And due to the setting of the inclined rod 157, the gravure printing plate cylinder 11 relies on its own gravity to make the support shaft 12 located at the lowermost side between the inclined rod 157 and the insertion frame 155, avoiding the rolling of the gravure printing plate cylinder 11 during the handling and loading process. Moreover, through this structure, the gravure printing plate cylinder 11 with support shafts 12 of different sizes can be moved, without the need for operators to replace equipment components, improving the processing efficiency.

[0031] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
