[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1 , 2 As shown in Figure 3, in this embodiment, a packaging printing ink plate roller scraper correction device is proposed, including an adjustment plate 1, with a first wall plate 2 and a second wall plate 3 at both ends of the adjustment plate 1, and the lower ends of the first wall plate 2 and the second wall plate 3 are fixedly connected to the upper end of the adjustment plate 1.

[0021] An assembly plate 7 is provided between the first wall plate 2 and the second wall plate 3, and the assembly plate 7 is placed above the adjusting plate 1. Both ends of the assembly plate 7 are rotatably connected to the first wall plate 2 and the second wall plate 3 through a rotating pin 9. A scraper 8 is provided on each side of the assembly plate 7, and the scraper 8 is detachably connected to the assembly plate 7. The assembly plate 7 is mounted above the adjusting plate 1 through the first wall plate 2 and the second wall plate 3, and can be rotated above the adjusting plate 1. Two scrapers 8 are respectively mounted on both sides of the assembly plate 7. When the assembly plate 7 rotates, the two scrapers 8 will also move accordingly.

[0022] A lifting assembly for adjusting the height of the adjusting plate 1 is provided at the lower end of the adjusting plate 1, and a transmission box 4 is provided on the side of the second wall plate 3 away from the first wall plate 2, and a self-locking transmission mechanism for controlling the rotation of the assembly plate 7 is provided in the transmission box 4. The height of the assembly plate 7 is controlled by the lifting assembly, and when the scraper 8 deviates from the ink roller, the lifting assembly will cooperate with the self-locking transmission mechanism to correct the scraper 8.

[0023] When one of the scrapers 8 on the assembly plate 7 has a problem, the assembly plate 7 is controlled to rotate 180 degrees through the self-locking transmission mechanism, and the other scraper 8 will take over the work. After the replaced scraper 8 is removed, a new scraper 8 is reassembled. During the entire process of replacing the ink scraper, there is no need to stop the entire equipment, which is convenient for disassembly and maintenance, and improves work efficiency.

[0024] Regarding the connection and assembly between the scraper 8 and the assembly plate 7: the scraper 8 is provided with a knife seat 10 on the side facing the assembly plate 7, and the assembly plate 7 is provided with a slot 12 on the side facing the scraper 8. The knife seat 10 is inserted into the slot 12 and plugged with the slot 12. A positioning component is provided at the matching position between the slot 12 and the knife seat 10. The knife seat 10 is fixed to the scraper 8. When the scraper 8 is assembled to both sides of the assembly plate 7, the knife seat 10 is inserted into the slot 12 and the knife seat 10 is locked using the positioning component.

[0025] Specifically, the positioning assembly includes positioning bolts 11 mounted on the four corners of the assembly plate 7. The positioning bolts 11 are inserted into the slots 12 and are threadedly connected to the assembly plate 7. The positioning bolts 11 are threadedly connected to the positioning holes 13 provided at both ends of the knife holder 10. When the knife holder 10 is pulled out of the slots 12 and the scraper 8 is replaced, the positioning bolts 11 are rotated to unscrew the positioning bolts 11 from the positioning holes 13. Two positioning bolts 11 are fixed at both ends of the knife holder 10.

[0026] When inserting the knife seat 10 into the slot 12, the positioning bolt 11 is used to fix the knife seat 10. Since the positioning bolts 11 are arranged at both ends of the knife seat 10, during the assembly process, the unfixed end of the knife seat 10 will slide out of the slot 12, and the staff needs to hold it continuously. In this regard, the assembly plate 7 is provided with a second magnetic block 15 on the side facing the knife seat 10. The second magnetic block 15 is fixedly connected to the assembly plate 7, and the second magnetic block 15 is attracted to the first magnetic block 14 fixed to the upper end of the knife seat 10. After the knife seat 10 is pushed into the slot 12, the second magnetic block 15 on the assembly plate 7 will be attracted to the first magnetic block 14 on the knife seat 10, and the knife seat 10 pushed into the slot 12 will remain fixed.

[0027] About the self-locking transmission mechanism: the self-locking transmission mechanism includes a worm 16 and a worm wheel 17 arranged in the transmission box 4, the worm wheel 17 is fixedly connected to the rotating pin 9, the worm 16 is placed below the worm wheel 17 and meshes with the worm wheel 17, and a motor 18 is arranged on the outside of the transmission box 4, and the output end of the motor 18 is fixedly connected to the worm 16. The motor 18 drives the worm 16 to rotate, and the worm 16 meshes with the worm wheel 17 during rotation, thereby driving the worm wheel 17 to rotate. When the worm wheel 17 rotates, the assembly plate 7 will also rotate. The worm wheel 17 and worm 16 transmission has self-locking properties. When the worm 16 stops rotating, the assembly plate 7 will not deflect under the meshing of the threaded surfaces between the worm wheel 17 and the worm 16, and the scraper 8 is more stable when working.

[0028] The assembly plate 7 is sleeved on the outside of the worm 16 and the worm wheel 17, which can prevent the worm 16 and the worm wheel 17 from being exposed to the outside, thereby increasing the service life of the worm 16 and the worm wheel 17. To facilitate maintenance of the worm 16 and the worm wheel 17, a plurality of mounting bolts 19 are mounted on both sides of the transmission box 4. The mounting bolts 19 pass through the transmission box 4 and are threadedly connected to the bolt holes provided on both sides of the second wall plate 3. When the transmission box 4 is removed from the second wall plate 3, the mounting bolts 19 can be screwed out of the bolt holes.

[0029] About the lifting assembly: The lifting assembly includes a fixed plate 5, which is placed below the adjustment plate 1. Electric push rods 6 are provided at both ends of the fixed plate 5. The mounting end of the electric push rod 6 is fixedly connected to the fixed plate 5, and the output end of the electric push rod 6 is fixedly connected to the adjustment plate 1. The output ends of the two electric push rods 6 are respectively fixed to the two ends of the adjustment plate 1. When the electric push rods 6 push the adjustment plate 1 to rise, the assembly plate 7 and the scraper 8 will also rise together.

[0030] Working principle: The height of the assembly plate 7 is controlled by the lifting assembly. When there is a deviation between the scraper 8 and the ink roller, the lifting assembly will cooperate with the self-locking transmission mechanism to correct the scraper 8. When one of the scrapers 8 on the assembly plate 7 has a problem, the assembly plate 7 is controlled by the self-locking transmission mechanism to rotate 180 degrees, and the other scraper 8 will take over its work. After the replaced scraper 8 is removed, a new scraper 8 is reassembled. During the entire process of replacing the ink scraper, there is no need to stop the entire equipment, which is convenient for disassembly and maintenance, and improves work efficiency.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above implementation book only describes the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
