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.

[0024] like Figures 1 to 5As shown, this utility model provides a heavy-duty corrugated cardboard packaging box recycling device, including a recycling rack 1. The recycling rack 1 is equipped with a conveyor belt 2 and a tearing belt 3. The outer surfaces of the conveyor belt 2 and the tearing belt 3 are fixedly covered with spikes. The conveyor belt 2 and the tearing belt 3 are each equipped with two left and right transmission components 4. The rear end of one of the transmission components 4 extends to the back of the recycling rack 1 and is connected to a drive motor 5.

[0025] The conveyor belt 2 is horizontal, and the tearing belt 3 is inclined. There is a gap between the ends of the tearing belt 3 and the conveyor belt 2 that are close to each other. An adjusting fastening component 6 is provided on both the front and rear sides of the recycling rack 1, which is connected to the end of the tearing belt 3 away from the conveyor belt 2. Both ends of the conveyor belt 2 and one end of the tearing belt 3 are rotatably connected to the recycling rack 1 through the corresponding transmission components 4. The other end of the tearing belt 3 is movably connected to the recycling rack 1 through the adjusting fastening component 6. Due to the arrangement of the conveyor belt 2 and the tearing belt 3, with the cooperation of the transmission component 4 and the support plate 7, the cone-shaped spikes between them can continuously tear thicker corrugated cardboard, making it gradually thinner. This not only reduces cutting energy consumption and improves crushing efficiency, but also effectively ensures the dissolution efficiency of the fragments during pulping.

[0026] like Figure 5 As shown, support plates 7 are provided on the sides of the inner cavities of the conveyor belt 2 and the tearing belt 3. The support plates 7 in the conveyor belt 2 are fixedly connected to the recycling rack 1. The two ends of the support plates 7 in the tearing belt 3 are connected to the transmission components 4 at both ends of the tearing belt 3 through bearing rings.

[0027] like Figure 5 As shown, the outer surface of the support plate 7 and the inner walls of the conveyor belt 2 and the tearing belt 3 are smooth, and the opposing surfaces of the two support plates 7 are respectively attached to the inner walls of the conveyor belt 2 and the tearing belt 3. Due to the setting of the support plate 7, the stability of the movement of the close surfaces of the conveyor belt 2 and the tearing belt 3 can be ensured, thereby ensuring that the cones between them can stably tear the corrugated cardboard.

[0028] like Figure 5 As shown, the transmission assembly 4 includes a transmission roller 41 that is movably sleeved within the conveyor belt 2 and the tearing belt 3. A transmission rod 42 is inserted inside the transmission roller 41. Both ends of the transmission rod 42 pass through the transmission roller 41 and are rotatably sleeved on the recycling rack 1 via bearings.

[0029] like Figure 2 and Figure 5As shown, the front and rear ends of the transmission rod 42 on the side of the conveyor belt 2 away from the adjusting and fastening component 6 extend to the front and rear sides of the recycling rack 1, respectively, and are fixedly connected to the first transmission gear 43. The front and rear ends of the transmission rod 42 on the side of the tearing belt 3 away from the adjusting and fastening component 6 extend to the front and rear sides of the recycling rack 1, respectively, and are fixedly connected to the second transmission gear 44. The front end of the output shaft of the drive motor 5 is fixedly connected to the rear end of the transmission rod 42 on the side of the conveyor belt 2 near the adjusting and fastening component 6. The first transmission gear 43 and the second transmission gear 44 mesh with each other. The outer diameter of the first transmission gear 43 is larger than that of the second transmission gear 44. Due to the arrangement of the first transmission gear 43 and the second transmission gear 44, the conveyor belt 2 and the tearing belt 3 can be driven to move continuously under the cooperation of the transmission roller 41, the transmission rod 42 and the drive motor 5. More importantly, the movement speed of the tearing belt 3 can be greater than that of the conveyor belt 2. This ensures that while the conveyor belt 2 is conveying the cardboard, the speed difference between the conveyor belt 2 and the tearing belt 3 can achieve the effect of tearing thicker cardboard.

[0030] like Figure 2 As shown, the adjusting fastening assembly 6 includes a connecting slide 61 opened in the recycling rack 1. A locking slot 62 is opened on the front and rear sides of the outer surface and inner cavity of the recycling rack 1, which connects the front and rear sides of the connecting slide 61. The center of the arc of the connecting slide 61 and the locking slot 62 is located on the axis of the transmission roller 41 on the side of the tearing belt 3 away from the adjusting fastening assembly 6. The connecting slide 61 and the locking slot 62 are slidably engaged with a locking adjustment member 63 inside.

[0031] like Figures 2 to 4 As shown, the locking adjustment component 63 includes a first positioning block 631 slidably connected to a locking groove 62 near the inner cavity of the recycling rack 1. A connecting sleeve 632 is fixedly sleeved inside the first positioning block 631. A positioning bearing ring 633 is rotatably sleeved inside the connecting sleeve 632. A connecting shaft 634 is rotatably sleeved inside the positioning bearing ring 633. One end of the connecting shaft 634 is fixedly connected to both ends of the corresponding transmission rod 42 inside the tearing belt 3. One end of the connecting sleeve 632 passes through the communicating groove 61 and extends into the interior of another locking groove 62. Furthermore, a locking shaft 635 is threadedly connected to the other end of the locking shaft 635, which extends to the outside of the recycling rack 1 and is integrally formed with a second positioning block 636. An adjustment groove 637 is provided on the outer surface of the second positioning block 636. Due to the setting of the adjusting fastening component 6, with the cooperation of the transmission component 4, one end of the tearing belt 3 is always close to the top of the transmission belt 2, while the other end can change the distance between itself and the transmission belt 2 with the cooperation of the adjusting fastening component 6, so that it can be used to feed corrugated cardboard of different thicknesses, thereby improving the applicability and tearing effect.

[0032] Working principle and usage process of this utility model:

[0033] Based on the thickness of the heavy corrugated cardboard for recycling, the distance between one end of the tear strip 3 and the conveyor belt 2 is adjusted by adjusting the fastening assembly 6. Specifically, the locking shaft 635 and the second positioning block 636 are rotated by adjusting the groove 637 to increase the distance between them and the first positioning block 631, thereby contacting the two and the near surfaces of the two locking slots 62. Then, the locking adjustment member 63 is slid along the inside of the connecting groove 61 and the locking slot 62 to make the upper end of the tear strip 3 swing up and down around its other end. Then, the locking shaft 635 is rotated in the opposite direction to make the locking shaft 635 and the first positioning block 631 approach each other and clamp on the near surfaces of the two locking slots 62, thereby fixing the position of the corresponding transmission rod 42.

[0034] Then, turning on the drive motor 5 will drive the transmission belt 2 through the corresponding transmission rod 42. In turn, the transmission belt 2 and the tearing belt 3 will move synchronously under the cooperation of the first transmission gear 43 and the second transmission gear 44. Then, the rear corrugated cardboard will be fed into the transmission belt 2 and the tearing belt 3 at one end of the adjusting fastening component 6. Under the cooperation of the cones on the opposing surfaces of the transmission belt 2 and the tearing belt 3, the rear corrugated cardboard will be quickly torn apart.
