[0047] The main shaft 31 is arranged obliquely from bottom to top relative to the horizontal plane, and the main shaft 31 is rotatably installed through a bearing and penetrates the body 1; the first drive component 33 is preferably a drive motor in the embodiment of the present application, the first drive component 33 is installed on the outside of the body 1, and the first drive component 33 is located at the upper end of the main shaft 31, and the upper end of the main shaft 31 is coaxially fixedly connected to the drive shaft of the first drive component 33.

[0048] Reference Figure 2 and Figure 3 In the embodiment of the present application, the roughing pulp board 32 is a rectangular board, the long side direction of the roughing pulp board 32 is parallel to the long side direction of the main rotating shaft 31, and the short side direction of the roughing pulp board 32 is consistent with the radial direction of the main rotating shaft 31. A plurality of roughing pulp boards 32 are distributed around the main rotating shaft 31 in an annular array.

[0049] In the embodiment of the present application, two groups of rough cutting blade groups 3 are arranged side by side in the horizontal direction, and the two groups of rough cutting blades are respectively located under the two groups of crushing rollers 2, and the rough cutting blades 32 in the two groups of rough cutting blade groups 3 are suitable for active contact. The control system controls the first driving assembly 33 to drive the two groups of main shafts 31 to rotate towards each other, which can conveniently drive the rough cutting blades 32 to roughly cut the swollen color box scraps.

[0050] Reference Figure 3 and Figure 4 The fine-cutting blade set 4 includes an auxiliary rotating shaft 41 and a fine-cutting impeller 42 installed at one end of the auxiliary rotating shaft 41 .

[0051] Specifically, the upper end of the main shaft 31 is coaxially fixedly connected with a disc-shaped mounting plate 34 for mounting the fine cutting blade group 4. The auxiliary shaft 41 and the fine cutting impeller 42 are located between any two adjacent and coaxially arranged rough cutting pulp plates 32, and the auxiliary shaft 41 is parallel to the main shaft 31, and the auxiliary shaft 41 is also inclined from bottom to top relative to the horizontal plane. The upper end of the auxiliary shaft 41 is perpendicular to the mounting plate 34, and the upper end of the auxiliary shaft 41 is slidably connected to the mounting plate 34 along its axis.

[0052] The fine-cutting impeller 42 is coaxially rotatably mounted on the secondary rotating shaft 41 , and each secondary rotating shaft 41 may be provided with one or more fine-cutting impellers 42 , and the multiple fine-cutting impellers 42 are arranged at equal intervals along the axis of the secondary rotating shaft 41 .

[0053] In the embodiments of this application, refer to Figure 3 and Figure 4There are multiple groups of auxiliary rotating shafts 41 and fine-cutting impellers 42 evenly arranged around the main rotating shaft 31, and the number of groups of auxiliary rotating shafts 41 and fine-cutting impellers 42 is consistent with the number of rough cutting pulp boards 32 in each group of rough cutting paddle groups 3. The multiple groups of auxiliary rotating shafts 41 and fine-cutting impellers 42 are evenly arranged one by one between any adjacent and coaxially arranged multiple rough cutting pulp boards 32, and the lengths of the multiple groups of auxiliary rotating shafts 41 gradually increase or decrease along the axial direction of the main rotating shaft 31, and the multiple groups of auxiliary rotating shafts 41 and fine-cutting impellers 42 spirally rise and gradually approach the mounting disk 34, or spirally descend and gradually move away from the mounting disk 34.

[0054] While the main shaft 31 rotates, on the one hand, the secondary shaft 41 and the fine-cutting impeller 42 on the mounting plate 34 can rotate along with the main shaft 31 to cut the pulp fibers; on the other hand, the fine-cutting impeller 42 can rotate around the secondary shaft 41 under the action of the flow of the slurry to further cut the pulp fibers, thereby achieving fine cutting of the pulp fibers.

[0055] Further, in order to improve the fine cutting effect of the fiber cutting mechanism on the pulp fiber, refer to Figure 3 and Figure 4 A second driving assembly 35 for driving multiple groups of auxiliary rotating shafts 41 to slide synchronously in a direction parallel to the main rotating shaft 31 is also provided between the mounting plate 34 and the main rotating shaft 31. Two groups of filter plates 8 are installed side by side at the bottom of the machine body 1, below the coarse cutting paddle group 3 and the fine cutting blade group 4. A first fiber diameter detection assembly for obtaining the diameter of fibers in the pulp is provided at the bottom of the machine body 1, below the filter plates 8.

[0056] Specifically, refer to Figure 3 and Figure 4 The second driving assembly 35 includes an incomplete gear 351 , an incomplete gear ring 352 coaxially arranged on the outside of the incomplete gear 351 , and a plurality of driven gears 353 arranged between the incomplete gear 351 and the incomplete gear ring 352 .

[0057] The incomplete gear 351 is a special-shaped gear with gear teeth arranged on 1 / 2 of its outer circumference. The incomplete gear 351 is coaxially fixedly connected to the main shaft 31 .

[0058] The incomplete gear ring 352 is a special-shaped gear ring with gear teeth on 1 / 2 of the inner circumference. The incomplete gear ring 352 is coaxially fixed to the mounting plate 34, and the gear teeth of the incomplete gear ring 352 are opposite to the smooth surface portion of the outer circumference of the incomplete gear 351, and the smooth surface portion of the inner circumference of the incomplete gear ring 352 is opposite to the gear teeth of the incomplete gear 351.

[0059] Reference Figure 3 and Figure 4, multiple driven gears 353 are evenly distributed around the axis of the main shaft 31 on the outside of the incomplete gear 351, and the driven gear 353 is parallel to the mounting plate 34. The number of the driven gears 353 is consistent with the number of the secondary shaft 41, and the driven gears 353 correspond to the secondary shaft 41 one by one. The secondary shaft 41 rotates coaxially and is threadedly assembled on the middle of the driven gear 353. The driven gear 353 rotates around its axis and is connected to the mounting plate 34, and the driven gear 353 is meshed with the incomplete gear 351 and the incomplete gear ring 352 in sequence; when the driven gear 353 is meshed with the incomplete gear 351, the driven gear 353 rotates clockwise, and when the driven gear 353 is meshed with the incomplete gear ring 352, the driven gear 353 rotates counterclockwise.

[0060] While the main shaft 31 rotates, the mounting plate 34 and the incomplete gear 351 rotate synchronously with the main shaft 31, and the incomplete gear ring 352 rotates with the mounting plate 34; the incomplete gear 351 and the incomplete gear ring 352 alternate with each other and the incomplete gear 351 and the incomplete gear ring 352 are meshed with multiple driven gears 353 in sequence, so that the multiple driven gears 353 rotate synchronously, so that the auxiliary shaft 41 can slide back and forth up and down in a direction parallel to the axis of the main shaft 31, thereby making the pulp movement in the body 1 in a turbulent state, increasing the probability of pulp fibers contacting the rough cutting pulp plate 32 and the fine cutting impeller 42, and achieving more comprehensive and uniform fine cutting of the pulp fibers.

[0061] Reference Figure 3 and Figure 4 The filter plate 8 is a straight plate with an arc-shaped end surface.

[0062] Specifically, the filter plate 8 is located below the rough cutting blade group 3 and the fine cutting blade group 4, and the length direction of the filter plate 8 is parallel to the axial direction of the main rotating shaft 31, and the arc axis of the filter plate 8 coincides with the axis of the main rotating shaft 31. The filter plate 8 has a side close to the main rotating shaft 31 and is provided with multiple through grooves 811 at regular intervals along its arc direction. Each rough cutting blade plate 32 has at least one grinding block 321 protruding outward on the side away from the main rotating shaft 31. The multiple grinding blocks 321 in the same group of rough cutting blade group 3 form an outer spiral on the outer surface of the rough cutting blade group 3; during the rotation of the main rotating shaft 31, the grinding blocks 321 on the surface of the rough cutting blade group 3 can be movably arranged in the corresponding through grooves 811.

[0063] As the spirally shaped multiple grinding blocks 321 on the outer surface of the rough cutting paddle group 3 cooperate with the through grooves 811 on the limiting strip 81, during the rotation of the main shaft 31, the grinding blocks 321 and the limiting strip 81 can further cut the pulp fibers deposited on the surface of the filter plate 8, and drive the fiber pulp on the surface of the filter plate 8 to move with the rough cutting pulp plate 32, thereby further obtaining evenly broken good pulp.

[0064] Further, look back Figure 1 and Figure 2 A return pipe 5 is arranged on the outside of the machine body 1, and a first pulp outlet valve is arranged at the pulp outlet 11. The lower end of the return pipe 5 is connected to the first pulp outlet valve through a downwardly bent pipe 6, and the upper end of the return pipe 5 is connected to the machine body 1 above the fiber cutting mechanism; a first fiber diameter detection component is arranged near the pulp outlet 11, and the first fiber diameter detection component is used to monitor the diameter length of pulp fibers which are near the pulp outlet 11 and between the filter plate 8 and the machine body 1, and the first fiber diameter detection component is preset with a first diameter threshold.

[0065] During the color box processing, the operator can put the collected scraps of the color boxes into the machine body 1, use the crushing mechanism to crush the scraps into fragments, and use the water pipe 13 to introduce water or chemicals into the machine body 1 to swell the fragments; and after the fragments are swollen, use the fiber cutting mechanism to perform rough and fine cutting on the fragments to obtain a fiber suspension; and after a certain time interval, use the first fiber diameter detection component to obtain the fiber diameter in the fiber suspension at the bottom of the machine body 1, and compare the fiber diameter with the first diameter threshold, so as to effectively understand whether the fiber diameter meets the requirements for reuse.

[0066] When the fiber diameter meets the reuse requirements, the slurry at the slurry outlet 11 is discharged into the downward curved pipe 6 through the first slurry outlet valve and the slurry outlet 11; when the fiber diameter does not meet the reuse requirements, the control system controls the coarse cutting blade group 3 and the fine cutting blade group 4 to cut the slurry in the machine body 1 again until the pulp fiber diameter in the slurry at the slurry outlet 11 meets the first diameter threshold requirement.

[0067] Further, see Figure 1 and Figure 2 A pulp outlet pipe 7 is connected downwardly to the middle of the downward curved pipe 6, and a second pulp outlet valve and a second fiber diameter detection component are provided at the connection point between the downward curved pipe 6 and the pulp outlet pipe 7.

[0068] In the embodiment of the present application, the second fiber diameter detection component is used to obtain the diameter of the fiber in the slurry in the downward curved pipe 6. The second fiber diameter detection component is preset with a second diameter threshold, and the second diameter threshold is smaller than the first diameter threshold.

[0069] The pulp discharged into the lower curved pipe 6 through the pulp outlet 11 can be inspected again through the second fiber diameter detection component, and discharged through the pulp outlet pipe 7 when the second diameter threshold is met, and returned to the machine body 1 through the return pipe 5 for continuous fiber cutting when the second diameter threshold is not met, so that the scraps are broken up more evenly, further improving the quality of the pulp fiber suspension, and obtaining a uniformly broken, qualified, reusable pulp fiber suspension. At the same time, the plastic impurities in the scraps can float on the surface of the fiber suspension and be blown to the plastic outlet 12 through the air duct 14 for collection, thereby effectively realizing the paper-plastic separation of the scraps of the color box and improving the utilization rate of the scraps of paper.

[0070] In summary, the implementation principle of a color box processing device in an embodiment of the present application is as follows: during the color box processing, the operator can put the collected scraps of the color box into the body 1 of the processing device of the present application, first use the crushing mechanism to crush the scraps into fragments, then introduce water or chemicals into the body 1 through the water pipe 13 to swell the fragments, and after the fragments are swollen, use the fiber cutting mechanism to perform rough cutting and fine cutting on the fragments to obtain a fiber suspension; and use the first fiber diameter detection component and the second fiber diameter detection component to compare the fiber diameter in the fiber suspension with the first diameter threshold and the second diameter threshold, respectively, to find out whether the fiber diameter meets the reuse requirements, use the down-bend pipe 6 and the pulp outlet pipe 7 to discharge the pulp that meets the reuse requirements, and use the return pipe 5, the rough cutting paddle group 3 and the fine cutting blade group 4 to process the pulp that does not meet the reuse requirements again. At the same time, by taking advantage of the differences in basic properties such as water solubility and density of pulp fibers and plastic impurities, the fiber suspension in the machine body 1 is blown using the air duct 14 so that the pulp fibers meet the recycling requirements, thereby effectively reducing paper material loss and improving the utilization rate of color box scraps.

[0075] Step 3: Using the rough cutting blade group 3 and the fine cutting blade group 4, the swollen scraps are cut in all directions to form a fiber suspension, and in this process, the air duct 14 is used to continuously blow the plastic scraps on the surface of the fiber suspension to the plastic outlet 12;

[0076] Step 4: using the first fiber diameter detection component to obtain the fiber diameter in a fiber suspension at the bottom of the machine body 1, and performing a first comparison analysis between the fiber diameter in the fiber suspension and the first diameter threshold; based on the first comparison analysis result, continue to cut the fiber suspension in all aspects or pass the fiber suspension into the lower curved pipe 6;

[0077] Step 5: Use the second fiber diameter detection component to obtain the fiber diameter in the slurry at the lower bend pipe 6, and perform a second comparison analysis on the fiber diameter in the slurry and the second diameter threshold; based on the second comparison and analysis results, the slurry in the lower bend pipe 6 is discharged from the slurry outlet pipe 7 to obtain reusable good slurry, or the slurry in the lower bend pipe 6 is passed into the return pipe, and the above steps three to five are repeated until reusable good slurry is obtained.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
