Description

Technical Field

[0001] The utility model relates to the technical field of printing plate cylinder production, in particular to a printing plate cylinder engraving machine. Background Technique

[0002] Printing plate cylinders are important components used to transfer inks, coatings, or other printing materials onto printing substrates during the printing process. They are widely used in various printing equipment, such as intaglio printing, flexographic printing, and screen printing. During the production of the cylinder body, it is necessary to engrave it to complete the printing function.

[0003] When the existing printing plate cylinders are engraved, a clamping device is used to clamp a cylinder body. After that, the rotation of the cylinder body is required to cooperate with the engraving machine for the engraving work. After the engraving is completed, the cylinder body needs to be disassembled and then another cylinder body is put in. Since the cylinder body needs to rotate during engraving, most engraving machines can only process the reciprocating disassembly and assembly of individual cylinders. Therefore, during a large amount of cylinder body engraving work, the engraving efficiency will be reduced to a certain extent.

[0004] Therefore, it is necessary to design a printing plate cylinder engraving machine to solve the above problems. Content of the Utility Model

Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4, the present utility model provides a printing plate roller engraving machine, including a collection box 1. A workbench 2 is fixedly connected to the top of the collection box 1, and a reciprocating mechanism is arranged on the top of the workbench 2. Two symmetrically arranged threaded sleeve plates 9 are threadedly sleeved on the reciprocating mechanism. A first servo motor 8 is fixedly connected to the outer surface of one of the threaded sleeve plates 9, and an output shaft of the first servo motor 8 is fixedly connected to a third rotating shaft 23. One end of the third rotating shaft 23 is fixedly connected to a first disc 10, and two symmetrically arranged connecting columns 11 are fixedly connected to one side of the first disc 10. One end of the two connecting columns 11 is commonly fixedly connected to a second connecting disc 12. A third servo motor 24 is fixedly connected to the outer surface of the second connecting disc 12 on one side of the first servo motor 8, and an output shaft of the third servo motor 24 is fixedly connected to a fourth rotating shaft 25. One end of the fourth rotating shaft 25 is fixedly connected to a second gear 15. A second rotating shaft 17 is rotatably connected to the outer surface of the other threaded sleeve plate 9 on one side of the second gear 15. One end of the second rotating shaft 17 is fixedly connected to a third disc 16. Four first rotating shafts 13 distributed in a cross shape are rotatably connected to the adjacent sides of the second connecting disc 12 and the third disc 16. First gears 14 are fixedly sleeved on the outer surfaces of the four first rotating shafts 13 on one side of the second gear 15, and the four first gears 14 are all meshed with the second gear 15. One end of each of the eight first rotating shafts 13 is fixedly connected to a sleeve shaft block 21. An engraving device is arranged directly above the workbench 2. By means of the reciprocating mechanism, the distance between the two threaded sleeve plates 9 can be adjusted. Then, by adjusting the distance between the eight sleeve shaft blocks 21 on the two threaded sleeve plates 9, four printing plate rollers for engraving can be clamped. After the roller bodies are installed on the eight sleeve shaft blocks 21, by starting the third servo motor 24, the rotation of the fourth rotating shaft 25 is used to drive the second gear 15 to rotate. Thus, the rotation of the second gear 15 drives the four first gears 14 meshed with it to rotate synchronously. Then, by the rotation of the eight first rotating shafts 13, the four printing plate rollers between the eight sleeve shaft blocks 21 can be rotated synchronously. Then, the engraving device can be used to engrave the printing plate roller sent below the engraving device. By starting the first servo motor 8, the rotation of the third rotating shaft 23 and the two connecting columns 11 are used to drive the second connecting disc 12 to rotate. Thus, when each printing plate roller is engraved, the position of the printing plate roller is exchanged. After all the printing plate rollers are engraved, the distance between the two threaded sleeve plates 9 can be adjusted by means of the reciprocating mechanism to replace the printing plate rollers, so that the four printing plate rollers are engraved in a group of four, greatly improving the engraving work of the printing plate rollers.

[0021] It should be noted that the reciprocating mechanism in the above description includes a second servo motor 18. By turning on the second servo motor 18, the rotation of the bidirectional threaded rod 19 inside the two grooves at the top of the workbench 2 can be utilized to adjust the distance between the two threaded sleeve plates 9 that are inside the two grooves and are threadedly sleeved at both ends of the bidirectional threaded rod 19.

[0022] Furthermore, in order to facilitate the stability of the sliding of the two threaded sleeve plates 9 inside the two grooves, the two threaded sleeve plates 9 are respectively slidably arranged inside the two grooves, and both sides of the two threaded sleeve plates 9 are respectively in contact with both sides inside the two grooves.

[0023] Even further, in order to avoid pollution caused by debris generated during engraving, an opening is provided at the top of the collection box 1, and a plurality of openings are formed on the outer surface of the workbench 2. The plurality of openings communicate with the top of the collection box 1. One side of the collection box 1 is fixedly connected with an L-shaped square plate 26. One side of the L-shaped square plate 26 is fixedly connected with a fixing plate 6. The top of the fixing plate 6 is fixedly connected with an electronic telescopic rod 5. The top of the L-shaped square plate 26 is slidably inserted with a transparent cover 3. The top of the transparent cover 3 is fixedly connected with a connecting plate 4. The bottom of the connecting plate 4 is fixedly connected to the top end of the electronic telescopic rod 5. The engraving device is fixedly connected to the bottom of the connecting plate 4. When the engraving device at the bottom of the connecting plate 4 performs engraving, the debris will fall into the interior of the collection box 1 through the openings at the top of the workbench 2 under the shielding of the liftable transparent cover 3.

[0024] In order to facilitate the collection and cleaning of the debris collected inside the collection box 1, a material taking port is provided on one side of the collection box 1, and a plug 22 is movably installed outside the material taking port. Adjacent sides of the eight sleeve shaft blocks 21 are all provided with jacks.

However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0026] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable manner. In order to avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
