[0002] The regenerated corrugated paper is corrugated paperboard made of recycled waste paper as the main raw material. The waste paper such as recycled cartons and newspapers is made into paper pulp through processes such as sorting, disintegration and purification, and then the pulp ratio is optimized and a reinforcing agent (such as starch and nanocellulose) is added to solve the problem of regenerated fiber strength loss, so that the compressive strength of the product approaches that of virgin paper, thereby realizing the recycling of waste paper resources and significantly reducing the dependence on virgin wood and environmental impact.

DETAILED DESCRIPTION

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present application.

[0029] REFERENCE Figures 1-10 A paper pulp preparation device for producing recycled corrugated paper, comprising a support table 1, a pulping barrel 2 and a treatment tank 3 are arranged above and below the support table 1 respectively, the pulping barrel 2 is fixed above the support table 1 by a fixed frame, and the treatment tank 3 is fixed below the support table 1 by support legs. A pulping mechanism and a cleaning mechanism are arranged on the pulping barrel 2, so that pulping work and cleaning work can be carried out in the pulping barrel 2 respectively. The pulping barrel 2 is connected with a material injection pipeline 24 at the upper end and a discharge pipe 25 at the lower end, and the material injection pipeline 24 is used to deliver the waste paper raw material after soaking into the pulping barrel 2.

[0030] The pulping mechanism comprises two device boxes 4 fixedly connected to the outer wall of the pulping cylinder 2 and communicating with the pulping cylinder 2, the two device boxes 4 are symmetrically arranged and each is internally provided with an axle 5, one end of each of the two axles 5 located in the pulping cylinder 2 is fixedly connected with a pulping blade 6, and the axle 5 and the pulping blade 6 jointly form a pulping impeller for pulping the waste paper raw material. A rotating block 7 is rotatably connected to one side wall of the device box 4 away from the pulping cylinder 2, and the rotating block 7 is movably sealed with the pulping cylinder 2. One end of the axle 5 located in the device box 4 is fixedly connected with a moving rod 8 in the shape of a regular hexagon, one end of the moving rod 8 away from the axle 5 is slidably penetrated through the rotating block 7 and is slidably sleeved with a rotating sleeve 9, and the moving rod 8 is slidably sealed with the rotating block 7. The rotating sleeve 9 is fixedly connected with a transmission gear 11 at an end away from the moving rod 8, and the axle 5, the rotating block 7, the moving rod 8, the rotating sleeve 9 and the transmission gear 11 are coaxially arranged, and when the transmission gear 11 rotates, the pulping impeller can be coaxially rotated. The device box 4 is fixedly connected with a fixed frame 10, the rotating sleeve 9 is penetrated through the fixed frame 10 and is rotatably connected therewith, and the fixed frame 10 is used for fixing the positions of the transmission gear 11 and the rotating sleeve 9. The device box 4 is fixedly connected with an extension cylinder 12 at the upper end, and the extension end of the extension cylinder 12 is fixedly connected with a push plate 13, the moving rod 8 is penetrated through the push plate 13 and is rotatably connected therewith, and the extension cylinder 12 can drive the moving rod 8 to move through the push plate 13, so as to move the pulping impeller, so that the pulping impeller can be moved from the pulping cylinder 2 to the corresponding device box 4 or from the device box 4 to the pulping cylinder.

[0031] Specifically, the two extension cylinders 12 work synchronously, and when the two pulping impellers are moved into the pulping cylinder 2, the pulping work can be carried out, and after the pulping is stopped, the two pulping impellers can be moved into the corresponding device box 4, so as to carry out the pulp discharging work.

[0032] The cleaning mechanism comprises a cleaning ring plate 19 located in the pulping cylinder 2 and abuttingly arranged with the inner wall of the pulping cylinder 2, two vertically arranged lifting rods 20 fixedly connected with the upper end of the cleaning ring plate 19, the two lifting rods 20 are slidably penetrated through the top wall in the pulping cylinder 2 and are commonly fixedly connected with an end plate 21, a second motor 22 is fixedly installed at the upper end of the pulping cylinder 2, a threaded rod 23 is coaxially fixedly connected with the output end of the second motor 22, and the threaded rod 23 is penetrated through the end plate 21 and is threadedly connected therewith, and the second motor 22 drives the threaded rod 23 to rotate, so as to drive the end plate 21 to vertically ascend and descend, so that the cleaning ring plate 19 vertically ascends and descends in the pulping cylinder 2, and the residual paper pulp on the inner wall of the pulping cylinder 2 is cleaned.

[0033] Two device boxes 4 are slidably inserted with movable baffles 14 at both ends, and the two movable baffles 14 in the same device box 4 are provided with semicircular notches matched with the wheel shaft 5 at the opposite end. When the two movable baffles 14 are in contact, the wheel shaft 5 can be wrapped, and the rotation of the wheel shaft 5 is not affected. The lower end of the device box 4 is provided with a two-way threaded rod 15, and the two-way threaded rod 15 is threadedly connected with two moving plates 16. The two moving plates 16 are fixedly connected with the corresponding two movable baffles 14. The lower end of the device box 4 is fixedly provided with a first motor 17 for driving the two-way threaded rod 15 to rotate. The first motor 17 drives the two-way threaded rod 15 to rotate, which drives the corresponding two movable baffles 14 to move relatively, so that the two movable baffles 14 can be opened or closed.

[0034] Specifically, when the two movable baffles 14 are opened, the moving of the pulper impeller can be carried out. When the pulper impeller is working, the two movable baffles 14 remain closed, i.e. wrapped around the part of the wheel shaft 5 close to the moving rod 8. In this state, the waste paper raw material cannot enter the device box 4, so as to effectively pulp in the pulper cylinder 2. When the cleaning mechanism is working, the pulper impeller is first retracted into the corresponding device box 4, and the two movable baffles 14 remain closed, wrapping the part of the wheel shaft 5 away from the moving rod 8. In this state, not only the pulp is effectively prevented from entering the device box 4, but also the cleaning ring 19 can be smoothly moved to the bottom of the pulper cylinder 2 to complete the cleaning work.

[0035] The two device boxes 4 are communicated with water injection pipes 18, which facilitate water injection into the device box 4, so as to clean the pulper impeller in the device box 4.

[0036] The treatment tank 3 is provided with a stirring mechanism. The treatment tank 3 is funnel-shaped and is communicated with a residue collecting tank 26 at the lower end for collecting impurities such as plastic, metal and sand in the pulp. The stirring mechanism includes a rotating ring plate 28 rotatably connected to the upper end of the treatment tank 3. Four fixed rods 29 are fixedly connected to the inner circumferential wall of the rotating ring plate 28 and are inclined downward. The four fixed rods 29 are fixedly connected with a conical block 30 at the end away from the rotating ring plate 28. The conical surface of the conical block 30 is upwardly arranged and close to the upper discharge pipe 25. When the discharge pipe 25 discharges the pulp after pulping, the pulp can directly contact the conical block 30 and distribute outwardly, so as to be evenly scattered into the treatment tank 3. A plurality of stirring rods 31 vertically extending into the treatment tank 3 are fixedly connected to the four fixed rods 29. When the rotating ring plate 28 rotates, the four fixed rods 29 rotate, thereby driving the stirring rods 31 to make circular motion in the treatment tank 3.

[0037] Specifically, a certain amount of water is added to the treatment tank 3 in advance, and then the pulp entering the treatment tank 3 can be directly diluted, so that the stirring of the stirring rod 31 can quickly dilute the pulp, so that the impurities inside it are quickly separated, and under the action of the impurities' own gravity and the centrifugal force of the liquid in the treatment tank 3, the impurities can slide along the inner wall of the treatment tank 3 into the slag box 26, thereby effectively completing the impurity separation work.

[0038] The lower end of the slag box 26 is connected to a waste pipe 27 for discharging impurities, and the outer wall of the treatment tank 3 is connected to a slurry delivery pipe for delivering the treated slurry in the treatment tank 3. It should be noted that the slurry delivery pipe, the discharge pipe 25 and the waste pipe 27 are all equipped with electric valves, which are prior art and are not shown in the figure.

[0039] A driving mechanism is provided on the support platform 1. Two hydraulic cylinders 45 are fixedly installed on the outer circumference of the processing pool 3. The upper ends of the two hydraulic cylinders 45 are respectively provided with movably arranged contact balls 46. The driving mechanism includes an annular guide rail 32 fixedly installed on the support platform 1 and concentrically arranged with the pulping tube 2. Four sliding members 33 distributed in a rectangular shape are slidably connected to the annular guide rail 32. The inner sides of the four sliding members 33 are commonly fixedly connected with an annular rotating box 34. A bevel gear ring 35 is fixedly sleeved on the outer circumference of the rotating box 34. A third motor 36 is fixedly installed on the upper end of the support platform 1. The output end of the third motor 36 is coaxially fixedly connected with a bevel gear 37. The bevel gear 37 is vertically meshed with the bevel gear ring 35. The third motor 36 can drive the rotating box 34 to rotate through the bevel gear 37 and the bevel gear ring 35. Four connecting blocks 38 distributed in a rectangular shape are fixedly connected between the inner peripheral wall of the rotating box 34 and the rotating ring plate 28. Under the connecting action of the connecting blocks 38, when the rotating box 34 rotates, the rotating ring plate 28 rotates synchronously with it, and then the third motor 36 directly controls the stirring work of the stirring mechanism.

[0040] The upper end of the rotating box 34 is rotatably connected to an annular gear plate 39, which meshes with the two transmission gears 11. When the annular gear plate 39 rotates, it can simultaneously drive the two transmission gears 11 to rotate, thereby enabling the pulping mechanism to perform pulping work.

[0041] Four contact blocks 40 evenly distributed on the circumference are fixedly connected to the lower end of the annular gear plate 39. An annular top plate 43 is provided below the rotating box 34. Four lifting columns 41 evenly distributed on the circumference are fixedly connected to the upper end of the top plate 43. The four lifting columns 41 all pass through the lower end of the rotating box 34 and are slidably connected thereto. One end of the four lifting columns 41 located in the rotating box 34 is fixedly connected to a push block 42. Two contact balls 46 are both provided in contact with the lower end of the top plate 43. A spring 44 is fixedly connected between the top plate 43 and the lower end of the rotating box 34 to facilitate the effective downward resetting of the top plate 43. The lower end of the contact block 40 is blade-shaped to prevent the contact block 40 and the push block 42 from being opposed to each other.

[0042] Specifically, when the shredding mechanism needs to be driven to work, two hydraulic cylinders 45 need to work synchronously to drive two contact balls 46 to move upwards to top the top plate 43. The upward movement of the top plate 43 can make the four push blocks 42 move to the position height of the contact block 40. Then, when the third motor 36 drives the rotating box 34 to rotate, the contact block 40 in the rotating box 34 can contact the corresponding contact block 40, thereby pushing the annular tooth plate 39 to rotate synchronously with the rotating box 34 by the contact block 40. When the annular tooth plate 39 rotates, it can drive the two transmission gears 11 to rotate at high speed, so that the shredding impeller reaches a high-speed shredding state.

[0043] Further, the upper state allows the driving mechanism to drive the stirring mechanism and the shredding mechanism to work simultaneously. In this state, the shredding work and the impurity separation work are synchronized. Since the shredding time is short, only two hydraulic cylinders 45 need to work synchronously to perform multiple shredding operations under the condition that the driving mechanism continues to run. The process will not affect the continuous work of the stirring mechanism, greatly saving the power cost, and without the need for additional impurity separation equipment. After shredding, the impurities can be separated quickly and effectively, and the paper pulp after impurity removal and dilution can be obtained directly, which is convenient for subsequent ink removal and beating work.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
