[0002] Paper tubes are mainly used in the production of cores and pipes, including industrial pipes, mulch pipes, firework pipes, textile pipes, spiral pipes, pagoda pipes, parallel pipes, various paper corner protectors, cartons, honeycomb cardboard, etc.

[0003] In the prior art, patent announcement number CN217888221U discloses a hardboard shredding device for yarn tube base paper production, including a shredding device body. A second groove is formed inside the shredding device body, and a motor is fixedly connected inside the second groove. A drive shaft is fixedly connected to one end of the motor output shaft, and a disc is fixedly connected to the top of the drive shaft. This utility model, by setting a drive shaft at one end of the motor output shaft, a disc at one end of the drive shaft, a connecting rod at one end of the rack, a fixing rod inside the second groove, a power gear on the outer wall of the rotating rod, and a shredding blade on the outer wall of the stabilizing rod, presents a solution.

[0004] The aforementioned device shreds cardboard by rotating a high-speed shredder blade. During the shredding process, workers need to feed the cardboard into the feed chute. If the shredder blade is rotating at high speed when the cardboard is being fed into the shredder, this poses a risk of cutting the user. Furthermore, if the user attempts to directly feed large pieces of cardboard into the feed chute, this can easily cause the shredder blade to jam, thus affecting the normal operation of the machine and the user's safety. Utility Model Content

[0005] The purpose of this invention is to provide a paperboard shredding device for producing paperboard from yarn tube base paper, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paperboard shredding device for producing yarn tube base paper, comprising a shredding chamber, an inlet fixedly installed on the shredding chamber, an outlet fixedly installed on one side of the shredding chamber, a shredding mechanism installed inside the shredding chamber and the inlet, the shredding mechanism comprising a first conveying roller and a second conveying roller rotatably installed inside the inlet, and a shredding blade holder rotatably installed inside the shredding chamber, an annular blade fixedly installed on the first conveying roller, a blade groove opened on the second conveying roller, and an air supply mechanism connected to the bottom of the shredding chamber.

[0007] Preferably, the first conveying roller, the second conveying roller, and the crushing blade holder are all fixedly equipped with synchronous gears, and the synchronous gears mesh together in pairs. The first conveying roller and the crushing blade holder are both fixedly equipped with sprockets, and chains are installed on the sprockets.

[0008] Preferably, a rotating shaft is fixedly installed on the first conveying roller, the second conveying roller, and the crushing blade holder. The first and second conveying rollers are rotatably installed in the feed inlet via the rotating shaft, and the crushing blade holder is rotatably installed in the crushing chamber via the rotating shaft.

[0009] Preferably, the annular blade is rotatably mounted in the feed inlet via a first conveying roller, and the annular blade is embedded in the second conveying roller via a blade groove.

[0010] Preferably, the air supply mechanism includes a volute fixedly installed at the bottom of the crushing chamber and a motor fixedly installed on one side of the crushing chamber. A movable shaft is rotatably installed inside the volute, and a cross-flow fan is fixedly installed on the movable shaft. A drive shaft is fixedly installed at the output end of the motor. Pulleys are fixedly installed on both the drive shaft and the movable shaft, and a drive belt is installed on the pulleys.

[0011] Preferably, a bearing is installed on the volute, and the movable shaft is rotatably mounted on the volute via the bearing.

[0012] Preferably, the cross-flow fan blade is rotatably mounted inside the volute via a movable shaft, the bottom of the pulverizing chamber is provided with an air inlet, the volute is connected to the pulverizing chamber through the air inlet, and a protective net is provided inside the air inlet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, after the motor starts, it drives the shredder holder to rotate, thereby performing the shredding task. The rotation of the shredder holder will drive the sprocket at one end to rotate synchronously, and then the chain will cause the first conveyor roller to rotate accordingly. Under the coordinated action of the synchronous gears, the first conveyor roller and the second conveyor roller achieve synchronous rotation. Through the coordinated work of the first conveyor roller and the second conveyor roller, the cardboard can be smoothly fed into the shredding chamber, thereby improving the safety of the feeding process. At the same time, during the feeding process, the annular blades cut the cardboard into smaller strips, effectively preventing the shredder holder from jamming.

[0015] 2. In this application, during the crushing process, the motor drives the pulley to rotate, which in turn drives the movable shaft to rotate. The rotation of the movable shaft causes the cross-flow fan to move, which disturbs the external airflow and guides it into the crushing chamber. The airflow flows around the inner wall of the crushing chamber and is eventually discharged through the discharge port. During the discharge process, the airflow carries fine paper scraps through the discharge port, while larger paper scraps continue to be crushed inside the crushing chamber to ensure that the size of the discharged paper scraps meets the predetermined standard.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a paperboard shredding device for producing yarn tube base paper, including a shredding box 1, a feed inlet 2 fixedly installed on the shredding box 1, a discharge outlet 3 fixedly installed on one side of the shredding box 1, a shredding mechanism 4 installed inside the shredding box 1 and the feed inlet 2, and an air supply mechanism 5 connected to the bottom of the shredding box 1. During the feeding process, the annular blade 404 will cut the paperboard into smaller paper strips to prevent the shredding blade holder 401 from getting stuck, and can screen out smaller paper scraps for discharge.

[0023] like Figure 2 and Figure 3As shown, the crushing mechanism 4 includes a first conveying roller 403 and a second conveying roller 405 rotatably mounted in the feed inlet 2, and a crushing blade holder 401 rotatably mounted in the crushing chamber 1. A ring-shaped blade 404 is fixedly mounted on the first conveying roller 403, and a blade groove 406 is provided on the second conveying roller 405. Synchronous gears 402 are fixedly mounted at the ends of the first conveying roller 403, the second conveying roller 405, and the crushing blade holder 401, and the synchronous gears 402 mesh together in pairs. A sprocket 407 is fixedly mounted at the end of the first conveying roller 403 and the end of the crushing blade holder 401. A chain 408 is mounted on the sprocket 407. A rotating shaft is fixedly mounted on the first conveying roller 403, the second conveying roller 405, and the crushing blade holder 401. The first conveying roller 403 and the second conveying roller 405 are rotatably mounted in the feed inlet 2 through the rotating shaft, and the crushing blade holder 401 is rotatably mounted in the crushing chamber 1 through the rotating shaft.

[0024] Specifically, after the motor 501 is started, it drives the shredder holder 401 to rotate, thereby performing the shredding operation. As the shredder holder 401 rotates, it drives the sprocket 407 connected to one end of it to rotate as well. The rotation of the sprocket 407 drives the first conveyor roller 403 to rotate via the chain 408. Under the coordinated action of the synchronous gear 402, the first conveyor roller 403 and the second conveyor roller 405 can rotate synchronously. This synchronous rotation mechanism allows the first conveyor roller 403 and the second conveyor roller 405 to work together, smoothly feeding the cardboard into the shredding chamber 1, greatly improving the safety of the feeding process. Simultaneously, during the feeding process, the annular blade 404 cuts the cardboard into smaller strips, effectively preventing the shredder holder 401 from jamming due to excessively large cardboard.

[0025] like Figure 2 and Figure 4 As shown, the air supply mechanism 5 includes a volute 505 fixedly installed at the bottom of the crushing chamber 1 and a motor 501 fixedly installed on one side of the crushing chamber 1. A movable shaft 504 is rotatably installed inside the volute 505. A cross-flow fan blade 503 is fixedly installed on the movable shaft 504. A drive shaft 506 is fixedly installed at the output end of the motor 501. Pulleys 507 are fixedly installed on both the drive shaft 506 and the movable shaft 504. A drive belt 502 is installed on the pulleys 507. A bearing is installed on the volute 505. The movable shaft 504 is rotatably installed on the volute 505 through the bearing.

[0026] Specifically, during the operation of the shredder, the motor 501 drives the pulley 507 on the drive shaft 506 to rotate. As the pulley 507 rotates, it transmits power to the movable shaft 504, causing the movable shaft 504 to also rotate. The rotation of the movable shaft 504 drives the rotation of the cross-flow fan 503. During its rotation, the cross-flow fan 503 disturbs the surrounding airflow, drawing it into the shredding chamber 1. Once inside the shredding chamber 1, this airflow flows along the inner wall of the chamber. Finally, this airflow exits the shredder through the discharge port 3. During the airflow's exit, it carries some smaller paper scraps through the discharge port 3. However, larger paper scraps, unable to be easily carried by the airflow, remain inside the shredding chamber 1 and continue the shredding process. This design ensures that only paper scraps meeting the size requirements are discharged from the shredder, thus guaranteeing the uniformity and quality of the shredding effect.

[0027] Working principle: First, start the motor 501. Starting the motor 501 will drive the shredder holder 401 to rotate, thus performing the shredding operation. The rotation of the shredder holder 401 will drive the sprocket 407 at one end to rotate. After the sprocket 407 rotates, the chain 408 drives the first conveyor roller 403 to rotate. Under the action of the synchronous gear 402, the first conveyor roller 403 and the second conveyor roller 405 will rotate synchronously. Thus, the first conveyor roller 403 and the second conveyor roller 405 work together to feed the cardboard into the shredding chamber 1, improving the safety of feeding. During the feeding process, the annular blade 404 will cut the cardboard into smaller strips, preventing the shredder holder 401 from jamming. Furthermore, during the crushing process, the motor 501 drives the pulley 507 on the drive shaft 506 to rotate. After the pulley 507 on the drive shaft 506 rotates, it drives the movable shaft 504 to rotate. After the movable shaft 504 rotates, it drives the cross-flow fan 503 to rotate. After the cross-flow fan 503 rotates, it disturbs the external airflow and enters the crushing chamber 1. The airflow entering the crushing chamber 1 flows around the inner wall of the crushing chamber 1 and finally exits through the discharge port 3. When the airflow is discharged, it will carry smaller paper scraps out through the discharge port 3, while larger paper scraps will remain in the crushing chamber 1 to continue to be crushed, ensuring that the size of the discharged paper scraps meets the requirements.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
