[0028] Reference Figures 1 to 3 This invention describes a waste cardboard crushing and mixing device according to an embodiment of the present invention.

[0029] Reference Figures 1 to 3 In some embodiments, the waste paperboard crushing and mixing device includes a body 10, a crushing mechanism 20, an eddy current separation mechanism 30, and a stirring magnetic attraction mechanism 40. The body 10 has a feed inlet 11 at the top and a discharge outlet 12 at the bottom for inputting and outputting waste paperboard. The crushing mechanism 20 is located inside the body 10, below the feed inlet 11, and is used for initial crushing of the waste paperboard. The eddy current separation mechanism 30 is located below the crushing mechanism 20 and is used to separate metal impurities from the waste paperboard. The stirring magnetic attraction mechanism 40 is located below the eddy current separation mechanism 30 and is used to further stir the crushed waste paperboard and remove metallic iron from the waste paperboard through the magnetic attraction component 43.

[0030] It should be noted that, referring to Figures 1 to 3 In some embodiments, the crushing mechanism 20 includes two sets of toothed rollers 21 and two first motors 22. The two sets of toothed rollers 21 are rotatably mounted on the machine body 10, and the crushing gears of the two sets of toothed rollers 21 are staggered. The two first motors 22 drive the two sets of toothed rollers 21 respectively. When waste paperboard enters from the feed inlet 11, the toothed rollers 21 efficiently crush the waste paperboard through the staggered crushing gears. The crushed waste paperboard falls into the eddy current separation mechanism 30 below.

[0031] Reference Figures 1 to 3 In some embodiments, the eddy current separation mechanism 30 includes an eddy current magnetic roller 31, a second motor 32, a discharge port 33, and a collection box 34. The eddy current magnetic roller 31 is rotatably mounted on the machine body 10, and the second motor 32 drives the eddy current magnetic roller 31 to rotate. The shredded waste paperboard enters the eddy current separation mechanism 30 through the shredding discharge channel 35. The eddy current magnetic roller 31 separates the metal impurities from the waste paperboard through the eddy current generated by its rotation. The separated metal impurities are collected by the collection box 34, while the shredded waste paperboard is discharged through the discharge port 33 and enters the stirring magnetic suction mechanism 40.

[0032] Reference Figures 1 to 3In some embodiments, the stirring and magnetic attraction mechanism 40 includes a third motor 41, a stirring assembly 42, and a magnetic attraction assembly 43. The third motor 41 is disposed inside the machine body 10 and is used to drive the stirring assembly 42 to rotate. The stirring assembly 42 is rotatably disposed inside the machine body 10 and is used to stir the shredded waste paperboard to ensure that the waste paperboard is uniformly mixed. The magnetic attraction assembly 43 is distributed in a ring on the inner wall of the bottom of the machine body 10 and is used to further magnetically attract the metal iron in the waste paperboard. The bottom of the machine body 10 is designed with a conical structure to facilitate the waste paperboard to concentrate towards the discharge port 12 during the stirring process, while the ring distribution of the magnetic attraction assembly 43 ensures that the metal iron is completely removed.

[0033] Reference Figure 3 In some embodiments, the feed inlet 11 at the top of the machine body 10 is designed with a sloped structure to facilitate the smooth entry of waste paperboard. The crushing discharge channel 35 adopts a sloped design to ensure that the crushed waste paperboard can smoothly slide into the eddy current separation mechanism 30. The collection box 34 is located at the end away from the crushing discharge channel 35, which facilitates the centralized collection and cleaning of metal impurities.

[0034] Through the above-mentioned multi-level synergistic effect, the waste paperboard crushing and mixing device of this utility model embodiment achieves efficient crushing of waste paperboard and complete separation of metal impurities, significantly improving the purity and recycling efficiency of subsequent pulp preparation.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
