[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a book printing spraying mechanism, including a processing box 1. The front of the processing box 1 is hinged with a door 2, which can seal the inside of the processing box 1 to prevent the paint from escaping to the outside and causing pollution during the spraying process. A glass window is provided on the front surface of the door 2, allowing the operator to directly observe the processing inside the processing box 1 and accurately control the spraying of the books. A sprayer 3 is provided on the top surface inside the processing box 1. When the sprayer 3 is activated, it can quickly spray the books placed inside the processing box 1. The above structures are all existing technologies in the field and will not be described in detail here. A partition 4 is fixedly connected inside the processing box 1. A motor 5 is fixedly connected to the bottom surface of the partition 4. The top output end of the motor 5 passes through the partition 4, and the bottom surface of the motor 5 is fixedly connected to the bottom surface inside the processing box 1, which can further improve the stability of the motor 5 during use.

[0033] Reference Figure 2 - Figure 4 A rotating cylinder 6 is fixedly connected to the top output end of the motor 5. When the motor 5 starts, it can drive the rotating cylinder 6 to rotate. An air pump 7 is fixedly connected inside the rotating cylinder 6. A rotating plate 8 is fixedly connected to the upper surface of the rotating cylinder 6. When the rotating cylinder 6 rotates, it will drive the rotating plate 8 to rotate synchronously. The output end on the side wall and the air inlet end on the top of the air pump 7 pass through the rotating cylinder 6 and the rotating plate 8 respectively. When the air pump 7 starts, it can draw air from the top of the rotating plate 8 and discharge it to the outside of the rotating cylinder 6, so that a negative pressure is formed above the rotating plate 8. A placement cylinder 9 is fixedly connected to the upper surface of the rotating plate 8. A rubber ring 10 is fixedly connected to the upper surface of the placement cylinder 9. The air pump 7 is located directly below the placement cylinder 9. When the air pump 7 starts, it will draw air from the inside of the placement cylinder 9.

[0034] When spraying the book, the book can be placed above the placement cylinder 9. Then, the air pump 7 is activated to extract air from the inside of the placement cylinder 9, creating a negative pressure inside the cylinder 9. This negative pressure then adsorbs the book, ensuring its stable placement. Simultaneously, the placement cylinder 9 elevates the book, maintaining a distance between the book and the rotating plate 8. The rubber ring 10 fills the gap between the placement cylinder 9 and the bottom of the book, further enhancing the negative pressure adsorption effect. A support cylinder 11 is fitted around the outside of the placement cylinder 9. The bottom surface of the support cylinder 11 is fixedly connected to the upper surface of the rotating plate 8. The support cylinder 11 can further support and limit the book, expand the support range for the bottom of the book, and further improve the stability of the book. During the subsequent spraying process of the book, the excess paint sprayed from the edge of the book will reach the rotating plate 8 and will not remain on the outside of the book and come into contact with the book. This allows the book to be separated directly from the excess paint during the subsequent handling of the book, avoiding paint from sticking to the bottom of the book and affecting the production quality.

[0035] Reference Figure 4 - Figure 5 A through groove 12 is provided on the upper surface of the rotating plate 8, through which the paint on the rotating plate 8 can be discharged. A collection box 13 is provided below the through groove 12 to collect the paint discharged from the through groove 12. A fixing rod 14 is fixedly connected to the inner wall surface of the right side of the processing box 1. An arc plate 15 is fixedly connected to the left end of the fixing rod 14. A scraper 16 is fixedly connected to the inner wall surface of the arc plate 15. The left end of the scraper 16 is in contact with the outer wall of the support cylinder 11. The inner diameter of the arc plate 15 is the same as the outer diameter of the rotating plate 8. The bottom surfaces of the arc plate 15 and the scraper 16 are both on the same horizontal plane as the upper surface of the rotating plate 8. The arc plate 15 and the scraper 16 are fixedly connected to the inside of the processing box 1 by the fixing rod 14.

[0036] After the book is coated and removed, the motor 5 can be started to drive the rotating plate 8 to rotate clockwise. During the rotation, the scraper 16 will scrape and push the coating on the surface of the rotating plate 8, while the arc plate 15 will block the coating to prevent it from falling off the outside of the rotating plate 8. When it has rotated almost one revolution, the through groove 12 will gradually return to its initial position. At this time, the scraped and pushed coating can fall into the collection box 13 through the through groove 12 for collection and reuse.

[0037] Working principle: When spraying the book, the book can be placed above the placement cylinder 9. As the air pump 7 is started, the air inside the placement cylinder 9 is extracted, creating a negative pressure inside the placement cylinder 9, which adsorbs and fixes the book under negative pressure. At the same time, the support cylinder 11 can further support and limit the bottom of the book, which can further improve the stability of the book. Then the sprayer 3 can be started to spray the book. During the process, the motor 5 can be started to drive the book to rotate, which can further improve the spraying efficiency. After the process is completed, the book that has been raised can be directly removed to avoid the book coming into contact with the paint on the rotating plate 8. Then the motor 5 can be started again to drive the rotating plate 8 to rotate at a low speed, so that the scraper 16 can scrape and push the excess paint on the surface of the rotating plate 8. Finally, this part of the paint can fall into the collection box 13 through the channel 12 for collection and processing, which is convenient for reuse.

[0038] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
