[0036] The outer surface of the dust suction hard pipe 213 is fixedly connected to the inside of the fixing piece 216 , and the adjusting nut 217 is arranged below the movable sleeve 215 .

[0037] The top of the low-angle inclined plate 701 is fixedly connected to the outer surface of the fixing seat 101. The low-angle inclined plate 701 is arranged on the side of the fixing seat 101 away from the support frame 3. The rotating shaft 704 is linearly arranged along the upper surfaces of the low-angle inclined plate 701 and the high-angle inclined plate 702.

[0038] The third cylinder 705 is symmetrically arranged on both sides of the low-angle inclined plate 701 , the third push plate 707 is arranged above the rotating shaft 704 , and the second pressure sensor 706 and the second ultrasonic sensor 708 are both electrically connected to the third cylinder 705 .

[0042] When in use, the motor 103 drives the active roller 104 to rotate through the conveying device 1 and the pre-processing device 2, and drives the conveyor belt 106 to convey with the cooperation of the driven roller 105. The book with the electronic label side facing up is placed on the conveyor belt 106, and the book moves with the conveyor belt 106. When the first ultrasonic sensor 205 detects the book, it transmits the signal to the second cylinder 202 and the fan 208, and the two groups of second cylinders 202 extend at the same time, driving the two second push plates 204 to move, so that the book is pushed straight by the two second push plates 204, and the first pressure sensor 205 detects the book. The sensor 203 monitors the thrust of the second push plate 204 on the book. When the thrust reaches the threshold set by the first pressure sensor 203, the first pressure sensor 203 transmits a signal to the second cylinder 202, causing the second cylinder 202 to retract to its original position. At the same time, the fan 208 is started, so that airflow is generated inside the fixed box 206. According to the Bernoulli principle, the pressure is small where the flow rate is large. Under the action of the air pressure difference, the outside air will enter the fixed box 206 along the dust collection hard pipe 213 and the hose 212, so that the hose 212 and the dust collection hard pipe 213 are internally generated. The dust on the surface of the book is absorbed by the wind shield 214, so that the subsequent electronic tag scanner 6 can clearly identify the electronic tag on the book. The absorbed dust falls into the dust box 211 along the dust suction hard pipe 213 and the hose 212. The dust box 211 can be taken out regularly to clean the dust inside. The height of the dust suction hard pipe 213 and the wind shield 214 can be adjusted by moving the movable sleeve 215 up and down, and then the adjusting nut 217 is screwed to the bottom of the movable sleeve 215, so that the movable sleeve 215 is limited to the current height, so that The wind hood 214 is placed at a suitable distance from the books as needed to facilitate dust absorption. The calibrated and dust-cleaned books are moved along the conveyor belt 106 to the bottom of the electronic label scanner 6, and the electronic label scanner 6 scans the electronic labels on the books. By setting up multiple groups of electronic label scanners 6, each group of electronic label scanners 6 corresponds to a category of books. When the electronic label scanner 6 scans a book belonging to this category, the corresponding first cylinder 4 extends, driving the first push plate 5 to move, and pushing the book to the corresponding secondary classification device 7, thereby preliminarily completing the sorting operation.

[0043] The books that have been initially sorted by category are pushed onto the rotating shaft 704 on the low-angle inclined plate 701 by the secondary classification device 7. With the cooperation of a plurality of rotatable rotating shafts 704, the books move downward along the low-angle inclined plate 701. When the second ultrasonic sensor 708 detects the books, it transmits a signal to the third cylinder 705. The two groups of third cylinders 705 extend at the same time, driving the two groups of third push plates 707 to move, and correcting the position of the books. When the second pressure sensor 706 detects that the thrust reaches a preset threshold, it transmits a signal to the third cylinder. 705, so that the third cylinder 705 retracts to the initial position. Since the slope of the low-angle inclined plate 701 is relatively gentle, the speed at which the books move downward is relatively slow, which facilitates the third push plate 707 to correct the position of the books. The corrected books continue to move downward along the rotating shaft 704 to the high-angle inclined plate 702. Smaller books first fall into the small through slot 709, medium-sized books continue to move downward and fall into the middle through slot 710, and larger books fall into the large through slot 711, thereby realizing secondary classification of books according to their sizes.

[0044] Through the collecting device 8 and the positioning device 9, the books entering the small through slot 709 fall into the small limiting frame 805, the books entering the middle through slot 710 fall into the middle limiting frame 806, and the books entering the large through slot 711 fall into the large limiting frame 807. Under the action of the small limiting frame 805, the middle limiting frame 806 and the large limiting frame 807, the fallen books are stacked up in sequence. When the third pressure sensor 903 detects that the pressure value from the collection box 801 reaches the preset threshold, it means that the collection box 801 is full, and the indicator light 908 lights up to remind the staff to move the collection box 801 away and Replace the empty collection box 801, pull the push rod 803 outward to make the moving wheel 802 move outward along the guide groove 902 until the collection box 801 leaves the positioning base 901, push the collection box 801 to the bookshelf, lift the small limiting frame 805, the middle limiting frame 806 and the large limiting frame 807 upward, so that the positioning plate 808 leaves the positioning groove 804, which is convenient for the staff to place the three piles of books. After all the books in the collection box 801 are taken out, align the positioning plates 808 on the small limiting frame 805, the middle limiting frame 806 and the large limiting frame 807 and insert them into the positioning groove 804, and lift the small limiting frame 805, the middle limiting frame 806 and the large limiting frame 807 upward. 05. The limiting middle frame 806 and the limiting large frame 807 are installed back into the collection box 801. When the collection box 801 is moved onto the positioning device 9, the moving wheel 802 is aligned with the guide groove 902, and the push rod 803 is pushed to move the moving wheel 802 onto the positioning base 901 until the moving wheel 802 moves to the innermost side of the guide groove 902. At this time, the moving wheel 802 is just above the third pressure sensor 903, the limiting small frame 805 is just below the small through groove 709, the limiting middle frame 806 is just below the middle through groove 710, and the limiting large frame 807 is just below the large through groove 711. In order to facilitate the falling of books, when the collection box 801 moves to the positioning base 901, the clamping plate 906 is pushed by the collection box 801 and moves toward the second side plate 904, and the movable rod 905 moves accordingly, and the spring 907 is compressed. When the collection box 801 stops at the required position on the positioning base 901, since the spring 907 is in a compressed state, the elastic force of the spring 907 makes the two clamping plates 906 clamped on both sides of the collection box 801, so that the collection box 801 is stably stopped at this position to prevent the impact force on the collection box 801 generated during the falling of the books from causing the collection box 801 to be displaced.
