Because books in the library are placed and stored for a long time, the books turn yellow due to long-time oxidation, the books are not easy to store due to brittleness, and acid generated by oxidation of the books due to long-time use can be neutralized through the calcium bicarbonate solution, so that the possibility of book yellowing is reduced, and the photographing and scanning effects are guaranteed.

Referring to fig. 5, 7, and 8, preferably, the centering device includes a shaking module for making the air nozzle 19 swing on the hanging plate 11 for blowing air, the shaking module includes a sliding seat 35, the sliding seat 35 is provided with four and equi-circumferential angles distributed on the hanging plate 11, the pull rope 8 is fixedly connected to one side of the sliding seats 35 located on the left and right sides away from the clamping plate 37, the lower surfaces of the sliding seats 35 located on the left and right sides are provided with guide rail plates 38, guide rail grooves 44 are formed through the guide rail plates 38, the upper surface of the hanging plate 11 is fixedly connected with an installation block 45, the upper surface of the hanging plate 11 is slidably connected with a swing rod 41 through the installation block 45, the upper surface of the swing rod 41 located at the guide rail grooves 44 is fixedly connected with guide rail columns 47, the guide rail columns 47 are slidably connected in the guide rail grooves 44, two ends of the swing rod 41 are rotatably connected with loop 42, and the loop 42 is rotatably connected with the air nozzle 19.

The blowing effect can be further improved, and the blowing area is ensured.

Example two:

referring to fig. 14, in the present embodiment, other structures are not changed, the present invention further provides a structural form of a rotating device, preferably, the blowing device further includes a rotating device for rotating the air nozzle 19 to blow air, the rotating device includes an air pot 34, a lower end of the air pot 34 is rotatably connected to the air nozzle 19, the upper surface of the hanging plate 11 is provided with a downwardly through swinging groove 31, the air nozzle 19 penetrates through the hanging plate 11 through the swinging groove 31, one end of the air nozzle 19 located in the air pot 34 is fixedly connected to a limiting plate 40, the upper surface of the limiting plate 40 is provided with a plurality of air hoppers 39, the air nozzle 19 is bent, the air hoppers 39 are made of plastic, and the air hoppers 39 are rectangular and have an inner hollow portion.

The working principle is as follows: when taking a picture scan, the smartphone is placed on the hanger plate 11 between the clamping plates 37. The book is opened and placed on the placing table 9 and clamped by the pressure lever 20, and the pressure lever 20 plays a role in fixing the book through the tension spring 21.

The correction work is carried out: motor 6 drives bevel gear 7 through the output shaft and rotates, bevel gear 7 drives bevel gear 3 and rotates, bevel gear 3 rotates and can promote slide 5 to slide in cross 32 through pushing away groove 4, thereby slide 5 can promote connecting plate 33 and move, all connecting plates 33 all can move to the center simultaneously, thereby drive slide 35 simultaneously to the intermediate motion, slide 35 can drive litter 36 to the intermediate motion, litter 36 can promote splint 37 to the intermediate motion, a plurality of splint 37 promote simultaneously can play the function of mobile phone correction, can push the mobile phone to the centre, thereby the mobile phone can be with abundant the shooting of books when guaranteeing to shoot. This while the motion of slide 35 still can stimulate 8 simultaneous motions of stay cord, and stay cord 8 can stimulate and draw a 52 lateral motion, when drawing a 52 lateral motion, can spread out the book completely, can also be floating the fold of book simultaneously, when drawing a 52 motion to the outside of placing cabinet 1, can press pressure switch 50 to make lamp strip 30 open, thereby play the effect of light filling, guaranteed the better going on of scanning work.

The work of the blowing device: when the pulling frame 52 is used for paving, the gear 26 is driven to rotate through the rack 22 at the lower end, the gear 26 rotates to drive the rotating rod 25 to rotate on the placing cabinet 1, the rotating rod 25 rotates to drive the rocker 24 to reciprocate, the rocker 24 drives the piston rod 53 to drive the piston in the air cylinder 23 to reciprocate back and forth, the air in the air cylinder 23 can be continuously conveyed into the communicating pipe 12 by matching with the two one-way valves 28, the communicating pipe 12 can convey the air into the air pot 34, the air pot 34 can blow out downwards through the air tap 19, dust and other foreign matters on the surface of a book can be blown down, and therefore the phenomenon that the blocking of characters affects the scanning effect of photos is prevented.

Operation of the rotating device: when the air in the air cylinder 23 is sent into the air pot 34 through the communicating pipe 12, because the air hopper 39 is arranged in the air pot 34, when the air enters the air pot 34, the air hopper 39 is blown to move reversely, and the directional movement of the air hopper 39 drives the air faucet 19 to rotate by driving the limiting disc 40, so that the air blowing coverage area of the air faucet 19 is greatly increased, and the air blowing effect can be improved.

The operation of the dithering module: when the slide 35 drives the clamping plate 37 to realize the centering function, the lower ends of the slide 35 at the left end and the right end are provided with the guide rail plate 38, and the guide rail plate 38 is provided with the guide rail groove 44, so that along with the movement of the slide 35, the guide rail plate 38 can push the guide rail column 47 to move leftwards and rightwards ceaselessly in the guide rail groove 44 through the guide rail groove 44, so that the guide rail column 47 can pull the swing rod 41 to move leftwards and rightwards at the same time in a reciprocating manner, so that the swing rod 41 can drive the ring sleeve 42 to drive the air pot 34 to rotate on the hanging plate 11 through the fixing plate 43, and the air blowing effect is further improved through the matching rotating device.

And (3) working of the maintenance module: when the pulling frame 52 moves outwards, the pulling frame 52 drives the gear 26 to rotate through the rack 22, and simultaneously drives the cam 29 to rotate, the pushing column 15 can be pushed to slide up and down on the placing cabinet 1 once every time the cam 29 rotates for one circle, so that the pushing column 15 can upwards press the button 14 once, the button 14 can spray the calcium bicarbonate solution diluted by alcohol in the spray bottle 13 through the nozzle 17, the calcium bicarbonate solution is spread on the book, the acid in the book can be neutralized through the calcium bicarbonate solution, and the function of maintenance is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
