When the number recorded by the counter 4 reaches the requirement of the booklet, the counter 4 drives the first motor 8 to start through the external controller. At this time, the rotation of the output shaft of the first motor 8 drives the rotation of the threaded rod 6, and the rotation of the threaded rod 6 drives the four connecting plates 7 to slide synchronously inside the sliding groove 5, and the paper will be counted by the counter 4. The movement of the connecting plate 7 drives the partition plate 9 and the guide frame 10 to move synchronously, so that after the paper passes through the partition plate 9 and falls into the guide frame 10, it is misaligned with the paper on the lower side located on the upper part of the workbench 3. Subsequently, the threaded rod 6 is repeatedly rotated forward and reversed, so that the partition plate 9 and the guide frame 10 can be driven to move back and forth left and right, and finally the function of dividing the books is realized. The practicality of the device is further improved through the above structure, and there is no need for staff to perform manual dividing, which saves manpower as much as possible, avoids the occurrence of dividing errors to a certain extent, and improves the accuracy of dividing the books.

[0029] In the above embodiment, the staff can set the counter 4 according to the number of sheets to be divided. When the number of sheets delivered reaches the specified number, the counter 4 can control the operation of the first motor 8 through the external controller.

[0030] Furthermore, a bidirectional threaded rod 15 is rotatably connected to the inside of the guide groove 13, and a second positioning plate 16 is threadedly sleeved on the outer surface of the rear end of the bidirectional threaded rod 15.

The second positioning plate 16 is slidably connected to the inside of the guide groove 13, and a connecting component is provided on the outer surface of the front end of the bidirectional threaded rod 15. A driving component is provided on the left surface of the workbench 3. When the staff organizes the papers completed by the volume, the bidirectional threaded rod 15 is driven to rotate by the driving component, and the rotation of the bidirectional threaded rod 15 drives the movement of the connecting component and the movement of the second positioning plate 16 respectively, and the movement of the connecting component drives the movement of the first positioning plate 14, and finally the first positioning plate 14 and the second positioning plate 16 are realized. The above structure further reduces the operating steps of the staff, thereby reducing the workload of the staff, and there is no need for the staff to organize the papers completed by the volume, which is convenient for the subsequent organization and collection of the papers, and has high practicality.

[0031] Furthermore, the driving assembly includes a second motor 24, which is fixedly connected to the left side surface of the workbench 3. A cavity is provided inside the workbench 3, and the cavity inside the workbench 3 is located on the rear side of the guide groove 13. The rear ends of the four bidirectional threaded rods 15 rotate and penetrate into the cavity inside the workbench 3. A driving shaft 25 is rotatably connected in the cavity inside the workbench 3. The driving shaft 25 is fixedly connected to the output shaft of the second motor 24. A bevel gear 26 is sleeved on the outer surface of the driving shaft 25. A bevel gear 26 is also sleeved on one end of the bidirectional threaded rod 15 located inside the workbench 3. The two bevel gears 26 are meshingly connected. The staff starts the second motor 24 to drive the rotation of the driving shaft 25, and the rotation of the bevel gear 26 is driven by the rotation of the driving shaft 25. At this time, because the bevel gear 26 on the surface of the driving shaft 25 is meshed with the bevel gear 26 on the surface of the bidirectional threaded rod 15, the four bidirectional threaded rods 15 will rotate synchronously, thereby driving the first positioning plate 14 and the second positioning plate 16 to sort the paper.

[0032] Further, the connecting assembly includes a connecting block 17, which is threadedly sleeved on the rear end outer surface of the bidirectional threaded rod 15, and the connecting block 17 is slidably connected to the inside of the guide groove 13. A first groove 18 is provided on the upper surface of the connecting block 17, and the first positioning plate 14 is rotatably connected to the inside of the first groove 18 through an axis. The lower end of the first positioning plate 14 is set to an arc surface, and two first through grooves 19 are provided on the side of the first positioning plate 14. The insides of the two first through grooves 19 are both slidably connected with sliding blocks 20. A second through groove 21 is provided inside the first positioning plate 14, and the second through groove 21 is connected to the first through groove 19. A fixing plate 22 is slidably connected inside the second through groove 21, and the fixing plate 22 is fixedly connected to the two sliding blocks 20.

The rotation of the bidirectional threaded rod 15 can drive the movement of the connecting block 17, and the movement of the connecting block 17 can drive the first positioning plate 14 connected to the inside of the first groove 18 through the rotation of the shaft to move. Later, when the sorted paper needs to be transported, by pressing the upper sliding block 20, the upper sliding block 20 will slide inside the upper first through groove 19, and the fixed plate 22 will slide inside the second through groove 21, and the spring 23 will contract, thereby driving the movement of the lower sliding block 20, and finally the lower sliding block 20 will be out of the slot 28. At this time, the first positioning plate 14 will be able to rotate freely, and then the first positioning plate 14 can be rotated to the inside of the second groove 27, and then the paper that has been sorted and sorted can be transported by setting the pulley 12.

[0033] Working principle:

[0034] When the automatic paper sorting mechanism of the printing press is in use, first, the paper to be sorted is transported through the conveying assembly 2 inside the conveying box 1. At this time, the paper will be counted by the counter 4 set on the upper part, and then the paper will be transported between the partition plates 9. The subsequent paper will fall into the inside of the guide frame 10, and then fall to the upper side of the fixed block 11 through the inclined groove inside the guide frame 10, and the front end of the paper will be blocked by the first positioning plate 14. When the number recorded by the counter 4 reaches the requirement for sorting, the counter 4 drives the first motor 8 to start through the external controller. At this time, the rotation of the output shaft of the first motor 8 drives the rotation of the threaded rod 6, and the rotation of the threaded rod 6 drives the four connecting plates 7 to slide synchronously inside the sliding groove 5. The movement of the connecting plate 7 drives the partition plate 9 and the guide frame 10 to move synchronously, so that after the paper falls into the inside of the guide frame 10 through the partition plate 9, it is misaligned with the paper on the lower side located on the upper part of the workbench 3. Subsequently, the threaded rod 6 is repeatedly rotated forward and reversed, so that the partition plate 9 and the guide frame 10 can be driven to move back and forth left and right, and finally the function of sorting is realized;

[0035] Then, when the staff sorts the separated papers, the staff starts the second motor 24 to drive the rotation of the driving shaft 25, and the rotation of the driving shaft 25 drives the rotation of the bevel gear 26. At this time, because the bevel gear 26 on the surface of the driving shaft 25 is meshed with the bevel gear 26 on the surface of the two-way threaded rod 15, the four two-way threaded rods 15 will rotate synchronously, and the rotation of the two-way threaded rod 15 will respectively drive the movement of the connecting assembly and the movement of the second positioning plate 16, and the movement of the connecting assembly will drive the movement of the first positioning plate 14, and finally the first positioning plate 14 and the second positioning plate 16 can sort the papers;

[0036] Finally, when the staff needs to transfer the paper, they press the upper sliding block 20. At this time, the upper sliding block 20 will slide inside the upper first through groove 19, and the fixed plate 22 will slide inside the second through groove 21. The spring 23 will shrink, thereby driving the movement of the lower sliding block 20. Finally, the lower sliding block 20 will be disengaged from the inside of the card slot 28. At this time, the first positioning plate 14 will be able to rotate freely, and then the first positioning plate 14 can be rotated to the inside of the second groove 27. Then, the pulley 12 can be set to transfer the completed divided and sorted paper.
