Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0029] Referring to Figures 1 - 8 , a paperboard shearing and paper separating machine for papermaking, including a paper separating machine main body 1, further including:

[0030] The first rotating shaft 2 is arranged on the paper separating machine main body 1, and a driving mechanism for driving the first rotating shaft 2 to rotate is arranged on the paper separating machine main body 1;

[0031] The wavy blade 3 has a wavy edge in the circumferential direction, and the wavy blade 3 is arranged on the outer wall of the first rotating shaft 2;

[0032] During use, when it is necessary to cut a cardboard with a wavy edge, the cardboard to be cut is arranged on the paper separating machine main body 1. The driving mechanism drives the first rotating shaft 2 to rotate, and the first rotating shaft 2 drives the wavy blade 3 to rotate, so that the cardboard passes above the wavy blade 3. The wavy blade 3 can cut the edge of the cardboard into a wavy shape, so that the shape of the cardboard edge meets the production requirements.

[0033] Refer to Figure 2 and Figure 3 As shown in [relevant figures], two shells 4 are fixedly connected to the outer wall of the first rotating shaft 2. A variety of size types of wavy blades 3 are arranged in both of the two shells 4. An installation block 5 is fixedly connected to the inner wall of the wavy blade 3, and the installation blocks 5 all slide on the outer wall of the first rotating shaft 2; when it is necessary to cut a cardboard into multiple cardboards with wavy edges, select an appropriate number and type of wavy blades 3 in the shell 4, slide the corresponding wavy blade 3 on the surface of the first rotating shaft 2 through the installation block 5, slide the installation block 5 and the wavy blade 3 to the corresponding positions, and the cardboard can be cut into multiple cardboards with wavy edges by multiple wavy blades 3.

[0034] Refer to Figure 4 and Figure 5 As shown in [relevant figures], a threaded column 6 is rotatably connected to the inner wall of the first rotating shaft 2. A rotating port is opened at the bottom end of the threaded column 6. A lifting rod 7 is threadedly connected to the outer wall of the threaded column 6. A limiting cavity 10 is opened in the first rotating shaft 2, and the lifting rod 7 is slidably connected in the limiting cavity 10. A plurality of lifting tubes 8 are fixedly connected to the lifting rod 7. An insertion block 9 is fixedly connected to the outer wall of the lifting tube 8, and a vertical channel 13 facing the insertion block 9 is opened in each of the installation blocks 5; when the wavy blade 3 slides to the corresponding position on the first rotating shaft 2 through the installation block 5, the threaded column 6 is rotated by a tool and the rotating port, the threaded column 6 drives the lifting rod 7 to move downward, the lifting rod 7 drives the lifting tube 8 and the insertion block 9 to move downward, and the insertion block 9 will be inserted into the vertical channel 13 of the installation block 5 to lock the installation block 5 and the wavy blade 3, lock the wavy blade 3 at this position, and prevent it from moving randomly.

[0035] Refer to Figure 5 、 Figure 7 and Figure 8, cooling chambers 11 are defined within the mounting blocks 5. Partition plates 12 are fixedly connected to the inner walls of the cooling chambers 11, and the cooling chambers 11 communicate with two corresponding vertical channels 13. During the high-speed rotation of the wavy blade 3 for slitting the cardboard, heat is generated by the wavy blade 3 and transferred to the mounting block 5. Cooling liquid is injected into the cooling chamber 11 through one of the vertical channels 13. The cooling liquid flows within the cooling chamber 11 and exits through the other vertical channel 13, carrying away the heat of the mounting block 5 to achieve the purpose of rapidly cooling the wavy blade 3.

[0036] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 8 , two cooling channels 15 are defined within the inner wall of the first rotating shaft 2. Fixed tubes 14 communicating with the corresponding cooling channels 15 are fixedly connected within the first rotating shaft 2. The lifting tubes 8 are slidably inserted within the corresponding fixed tubes 14. Two hollow ring blocks 16 are rotatably connected to the outer wall of the first rotating shaft 2, and the two hollow ring blocks 16 communicate with the corresponding cooling channels 15 respectively. Connectors 17 are mounted on the hollow ring blocks 16. During the process of inserting the insert block 9 into the vertical channel 13 to lock the wavy blade 3, the insert block 9 drives the lifting tube 8 to move downward, causing the lifting tube 8 to slide within the fixed tube 14. The lifting tube 8 extends into the vertical channel 13. When it is necessary to cool the wavy blade 3, cooling liquid is injected into one of the connectors 17 and the hollow ring block 16 by an external driving pump. The cooling liquid sequentially passes through one of the cooling channels 15, the lifting tube 8, the vertical channel 13 and enters the cooling chamber 11, then returns from the other vertical channel 13, the lifting tube 8, the cooling channel 15 to the other hollow ring block 16 and is discharged from the corresponding connector 17 to form a cooling circulation path.

[0037] Refer to Figure 6 , a circular plate 18 is fixedly connected to the inner wall of the lifting tube 8. A vertical cylinder 19 is slidably inserted through the middle of the circular plate 18. The part of the vertical cylinder 19 below the circular plate 18 is provided with round holes 20. A circular piece 21 is fixedly connected to the top end of the vertical cylinder 19. A spring 22 sleeved outside the vertical cylinder 19 is fixedly connected between the circular piece 21 and the circular plate 18;

[0038] A fixing seat 23 is fixedly connected inside the vertical channel 13. A through hole is formed in the middle of the fixing seat 23. A blocking block 24 facing the vertical cylinder 19 is arranged in the through hole. A plurality of elastic connecting ropes 25 are fixedly connected between the blocking block 24 and the inner wall of the vertical channel 13. A connecting pipe 26 is fixedly connected to the fixing seat 23. The connecting pipe 26 faces the circular plate 18, and the diameter of the connecting pipe 26 is the same as that of the circular plate 18. During the process of the insertion block 9 being inserted downward into the vertical channel 13, the lifting pipe 8 drives the vertical cylinder 19 to move downward. The vertical cylinder 19 first contacts the blocking block 24. The vertical cylinder 19 can press the blocking block 24 to move downward, causing the blocking block 24 to leave the through hole, and the connecting ropes 25 are stretched. When the blocking block 24 descends to a certain position, the vertical cylinder 19 moves upward relative to the circular plate 18, and the spring 22 is stretched, enabling some circular holes 20 to enter above the circular plate 18. Finally, the lifting pipe 8 will be sleeved on the outer wall of the connecting pipe 26. The cooling liquid can enter the vertical channel 13 through the lifting pipe 8, the circular holes 20, and the vertical cylinder 19. When the lifting pipe 8 moves upward and leaves the vertical channel 13, under the action of the connecting ropes 25 and the spring 22, the blocking block 24 re-blocks the through hole, the vertical cylinder 19 moves downward, and the circular holes 20 return to below the circular plate 18, automatically closing the lifting pipe 8 and the vertical channel 13.

[0039] Referring to Figure 1 , a second rotating shaft 27 is arranged on the paper separating machine main body 1. A plurality of circular blocks 28 are arranged on the outer wall of the second rotating shaft 27. The circular blocks 28 can be fixed on the second rotating shaft 27 through bolts. When it is necessary to cut a cardboard into a plurality of cardboards with wavy edges, after adjusting the position of the wavy blade 3, move and adjust the position of the circular block 28 on the surface of the second rotating shaft 27 to make the circular block 28 correspond to the wavy blade 3. The driving mechanism can drive the first rotating shaft 2 and the second rotating shaft 27 to rotate towards each other to cut the cardboard.

[0040] Working principle: When in use, when it is necessary to cut a cardboard with a wavy edge, place the cardboard to be cut on the paper separating machine main body 1. Drive the first rotating shaft 2 to rotate through the driving mechanism. The first rotating shaft 2 drives the wavy blade 3 to rotate, enabling the cardboard to pass above the wavy blade 3. The wavy blade 3 can cut the edge of the cardboard into a wavy shape, making the shape of the cardboard edge meet the production requirements.

[0041] When it is necessary to cut a cardboard into a plurality of cardboards with wavy edges, select the appropriate number and type of wavy blades 3 in the housing 4. Slide the corresponding wavy blade 3 on the surface of the first rotating shaft 2 through the mounting block 5, and slide the mounting block 5 and the wavy blade 3 to the corresponding positions. The cardboard can be cut into a plurality of cardboards with wavy edges through a plurality of wavy blades 3.

[0042] When the wavy blade 3 slides to the corresponding position on the first rotating shaft 2 through the mounting block 5, the threaded column 6 is rotated by the tool and the rotating mouth, the threaded column 6 drives the lifting rod 7 to move downward, the lifting rod 7 drives the lifting tube 8 and the insert block 9 to move downward, and the insert block 9 is inserted into the vertical channel 13 of the mounting block 5 to lock the mounting block 5 and the wavy blade 3, and the wavy blade 3 is locked in this position to prevent it from moving at will;

[0043] When the wavy blade 3 rotates at high speed to cut the cardboard, the wavy blade 3 generates heat, which is transferred to the mounting block 5. A cooling liquid is injected into the cooling chamber 11 through one of the vertical channels 13. The cooling liquid flows in the cooling chamber 11 and leaves from the other vertical channel 13. The cooling liquid takes away the heat of the mounting block 5, thereby achieving the purpose of rapidly cooling the wavy blade 3.

[0044] When the insert block 9 is inserted into the vertical channel 13 to lock the wavy blade 3, the insert block 9 drives the lifting tube 8 to move downward, so that the lifting tube 8 slides in the fixed tube 14, and the lifting tube 8 extends into the vertical channel 13. When the wavy blade 3 needs to be cooled, a cooling liquid is injected into one of the connectors 17 and the hollow circular ring block 16 through an external driving pump. The cooling liquid passes through one of the cooling channels 15, the lifting tube 8, and the vertical channel 13 in sequence and enters the cooling cavity 11, and then returns to the other hollow circular ring block 16 from the other vertical channel 13, the lifting tube 8, and the cooling channel 15, and is discharged from the corresponding connector 17 to form a cooling circulation passage;

[0045] When the plug block 9 is inserted downward into the vertical passage 13, the lifting pipe 8 drives the vertical cylinder 19 to move downward. The vertical cylinder 19 first contacts the blocking block 24. The vertical cylinder 19 can press the blocking block 24 to move downward, so that the blocking block 24 leaves the opening, and the connecting rope 25 is stretched. When the blocking block 24 drops to a certain position, the vertical cylinder 19 moves upward relative to the circular plate 18, and the spring 22 is stretched, so that part of the circular hole 20 enters above the circular plate 18. Finally, the lifting pipe 8 will be sleeved on the outer wall of the connecting pipe 26, and the cooling liquid can enter the vertical passage 13 through the lifting pipe 8, the circular hole 20, and the vertical cylinder 19. When the lifting pipe 8 moves upward to leave the vertical passage 13, under the action of the connecting rope 25 and the spring 22, the blocking block 24 blocks the opening again, the vertical cylinder 19 moves downward, and the circular hole 20 returns to the bottom of the circular plate 18, so that the lifting pipe 8 and the vertical passage 13 are automatically closed.

[0046] When a cardboard needs to be cut into multiple cardboards with wavy edges, after adjusting the position of the wavy blade 3, the position of the adjustment block 28 is moved on the surface of the second rotating shaft 27 so that the block 28 corresponds to the wavy blade 3. The driving mechanism can drive the first rotating shaft 2 and the second rotating shaft 27 to rotate towards each other to cut the cardboard.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
