Description

Technical Field

[0001] The present invention relates to the technical field of crushing and pulping, and particularly relates to an integrated machine for recycling, crushing and pulping corrugated paper waste. Background Art

[0002] Corrugated paper is a common type of paper, which is widely used in the packaging industry for its characteristics such as firmness, light weight, and compression resistance. It is mainly made of natural plant fibers such as wood pulp, rice straw pulp, and bagasse pulp through a series of complex processes. Corrugated paper has high tensile strength, tear resistance, and wear resistance, enabling it to effectively protect products from external damage. Moreover, the low density of corrugated paper makes the packaging lighter, reducing transportation costs. It also has good compression resistance and can withstand a certain degree of heavy pressure, which makes it widely used in the packaging industry.

[0003] In the patent with the publication number CN112934395B, an integrated machine for recycling, crushing and pulping corrugated paper waste is disclosed. The waste is shredded by a cutting device, and the shredded material is sent into a pulping device by a collecting device. When stirring and pulping, a paddle is used to stir the shredded material, and blades are arranged on the paddle to further cut the shredded material during rotation, ensuring the stirring effect.

[0004] However, the prior art still has the following defects:

[0005] In the existing stirring, a whole stirring component is arranged on one stirring shaft, so that the rotation speeds of the upper and lower stirring blades are the same. When the waste is shredded and falls, in the prior art, this one stirring component rolls the fallen shredded material into the slurry during the stirring process, and the rolling and stirring speed is slow. Moreover, when there is a large amount of shredded material falling after being broken by the crushing component, the shredded material will accumulate on the surface of the slurry, and it cannot be realized that the shredded material is quickly sucked to the bottom for wetting and then stirred, so that the stirring blades at the bottom cannot timely stir the involved waste, and the stirring blades at the bottom cannot be fully utilized, thus reducing the stirring and mixing efficiency of the entire stirring component.

[0006] When the existing stirring blades are stirring and mixing, they cannot realize the rapid circulation of the slurry stirring, so that the fallen waste is stirred at its respective horizontal positions, and the upper and lower slurries cannot be mixed and circulated. Often, it will cause the accumulation of waste at the top of the slurry, and the upper and lower slurries cannot be turned and stirred, resulting in obvious stratification between the upper and lower slurries and uneven mixing, and the mixing and stirring effect is poor. Summary of the Invention

[0007] In view of the problems existing in the prior art that during the process of pulping after crushing, the rapid entrainment and mixing of the crushed materials after they fall cannot be achieved, resulting in poor mixing and stirring effects and the inability to quickly achieve uniform mixing up and down, a corrugated paper waste recycling, crushing and pulping integrated machine is proposed.

[0008] Its purpose is to enable the crushed materials to be quickly entrained to the bottom of the slurry for mixing after falling, avoiding the accumulation of the crushed materials on the top of the slurry, accelerating the circulation and mixing between the upper and lower slurries, and enhancing the mixing and stirring effect.

[0009] The technical solution of the present invention is a corrugated paper waste recycling, crushing and pulping integrated machine, which includes a crushing box body, a water inlet pipe arranged on one side of the crushing box body, and a discharge pipe arranged at the bottom of one side of the crushing box body.

The crushing rollers are arranged in the inner cavity at the top of the crushing box body, and baffles symmetrically arranged on both sides of the top of the inner cavity of the crushing box body. And the two baffles are respectively inclined above the two crushing rollers. The crushing unit is used to crush corrugated paper waste, and the pulping unit is used to stir and pulp the crushed corrugated paper waste;

[0011] The pulping unit includes an upper stirring assembly arranged inside the crushing box body, a supporting assembly arranged at the bottom of the upper stirring assembly, and a lower stirring assembly arranged at the bottom of the supporting assembly; The upper stirring assembly includes an upper stirring column and upper stirring blades annularly arranged on the top of the upper stirring column, and the upper stirring blades are in an S shape.

[0012] Further, the upper stirring blade includes an entrainment part arranged on the side wall of the upper stirring column, and the entrainment part is in the shape of an inclined protrusion, and a steady flow part arranged on one side of the entrainment part, and the steady flow part is in the shape of an inclined depression.

[0013] Further, the supporting assembly includes four support rods annularly arranged in the middle of the crushing box body, a support column arranged at the bottom of the support rod, and the bottom of the upper stirring column is rotatably connected to the support column.

[0014] Further, the lower stirring assembly includes a stirring motor arranged at the bottom of the crushing box body, a lower stirring column arranged at the top of the output shaft of the stirring motor, and the top of the lower stirring column is rotatably connected to the support column. And lower stirring blades annularly arranged on the side wall of the lower stirring column, and the lower stirring blades are in a hook shape.

[0015] Further, the lower stirring piece includes a pushing part arranged on the side wall of the bottom of the lower stirring column, a flowing part arranged on one side of the pushing part, and a circulating part arranged on one side of the flowing part.

[0016] Further, the pushing part is in the shape of an inclined protrusion, the flowing part is in the shape of a twisted depression, and the circulating part is in the shape of an inclined deflection in the vertical direction.

[0017] Further, the pulping unit further includes a differential component arranged inside the support column. The differential component includes a differential assembly arranged between the upper stirring column and the lower stirring column, and a reset assembly arranged above the differential assembly on the upper stirring column;

[0018] The differential assembly includes a driving block arranged on one side of the top of the lower stirring column, a rotating groove opened on one side of the bottom of the upper stirring column, a driven block arranged on one side of the rotating groove, and the driving block is slidably connected in the rotating groove. A sliding groove is opened on the top of the lower stirring column, and the bottom of the upper stirring column is rotatably connected to the sliding groove. Limiting rods symmetrically arranged on both sides of the bottom of the upper stirring column, and a limiting groove opened on the inner wall of the support column;

[0019] The limiting groove includes an annular groove opened on the inner wall of the support column, and the annular groove is horizontal. A jacking groove is arranged on one side of the annular groove, a moving groove is arranged on one side of the jacking groove, and a falling-back groove is arranged on one side of the moving groove. The annular groove, the jacking groove, the moving groove and the falling-back groove are sequentially connected end to end to form a complete ring, and both limiting rods are slidably connected in the limiting groove.

[0020] Further, the reset assembly includes a reset groove opened on the inner wall of the support column and located above the limiting groove, a reset plate arranged in the reset groove, and the middle part of the reset plate is fixedly connected to the upper stirring column, and a reset piece sleeved on the upper stirring column, and both ends of the reset piece are respectively abutted against the reset plate and the bottom of the reset groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. During pulping, the upper stirring assembly rotates and stirs the falling waste materials. The upper stirring assembly is in the slurry. When the upper stirring column drives the upper stirring piece to rotate, the waste materials falling on the surface of the slurry will be stirred into the slurry, so as to be soaked and stirred. The two stirring assemblies arranged in the crushing box can make the slurry be fully mixed. The rapid mixing can effectively avoid the stratification of the slurry, ensure the uniformity and quality of the product, and improve the product quality.

[0023] 2. The flow stabilizing part on the upper stirring blade can stabilize the flow of the slurry pushed upward by the circulating part, preventing excessive agitation of the internal slurry caused by the too high agitation speed of the lower stirring blade, which may lead to splashing. Moreover, it can push the circulated slurry to the middle part of the upper stirring blade, that is, the middle position at the top of the slurry, enabling the slurry to form a complete top-down cycle within the entire crushing box. This not only improves the overall stirring and mixing efficiency of the slurry but also accelerates the speed at which the waste participates in the stirring and pulping process after it has just fallen.

[0024] 3. Through the differential component provided, an obvious pressure difference will occur between the upper and lower parts of the slurry, enabling the lower stirring assembly to quickly suck the slurry at the top into the lower part for stirring. Under the stirring action of the lower stirring assembly, the slurry is evenly mixed to form the required pulp. The stirring speed of the lower stirring assembly is fast, which can quickly stir the slurry evenly, improving the mixing efficiency and shortening the production cycle. Description of the Drawings

Detailed implementation manner

[0037] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manner of the present invention with reference to the drawings in the specification.

[0038] Example 1, refer to Figures 1 - 5 , which is the first embodiment of the present invention, provides a corrugated paper waste recycling and crushing pulping integrated machine, including a crushing box body 1, a water inlet pipe 11 installed on one side of the crushing box body 1, and a discharge pipe 12 installed at the bottom of one side of the crushing box body 1. It also includes a crushing unit 2 installed inside the crushing box body 1 and a pulping unit installed at the bottom of the crushing unit 2; the crushing unit 2 includes a crushing motor 21 installed on one side of the top of the crushing box body 1, two crushing rollers 22 rotating in opposite directions installed at one end of the output shaft of the crushing motor 21, the crushing rollers 22 are rotatably connected to the inner cavity at the top of the crushing box body 1, and baffles 23 symmetrically and fixedly connected to both sides of the inner cavity at the top of the crushing box body 1, and the two baffles 23 are respectively inclined and installed above the two crushing rollers 22. The crushing unit 2 is used to crush corrugated paper waste, and the pulping unit is used to stir and pulp the crushed corrugated paper waste; the pulping unit includes an upper stirring assembly 3 installed inside the crushing box body 1, a support assembly 4 installed at the bottom of the stirring assembly, and a lower stirring assembly 5 installed at the bottom of the support assembly 4; the upper stirring assembly 3 includes an upper stirring column 31 and upper stirring blades 32 fixedly connected to the top of the upper stirring column 31 in an annular array, and the upper stirring blades 32 are in an S shape.

[0039] Specifically, during pulping, the corrugated paper waste is shredded by the shredding unit 2, and the shredded corrugated paper falls into the pulping unit inside the shredding box 1. A certain amount of water is previously introduced into the pulping unit. The pulping unit stirs the shredded corrugated paper fragments, making the corrugated shredded material into a fibrous paste. Finally, the well-stirred slurry is discharged through the discharge pipe 12. During shredding, the shredding motor 21 starts to drive the two opposite shredding rollers 22 to rotate, shredding the corrugated paper waste that falls into them. The two baffle plates 23 are provided to guide the waste after being put in, making the waste slide into the middle of the two shredding rollers 22 and preventing the falling waste from falling from both sides of the shredding rollers 22. During pulping, the upper stirring assembly 3 rotates and stirs the falling waste. The upper stirring assembly 3 is in the slurry. When the upper stirring column 31 drives the upper stirring blades 32 to rotate, the waste falling on the surface of the slurry will be stirred into the slurry, so as to be soaked and stirred. The two stirring assemblies provided inside the shredding box 1 enable the slurry to be fully mixed. The rapid mixing can effectively prevent the slurry from stratifying, ensuring the uniformity and quality of the product and improving the product quality.

[0040] Referring to Figure 5 , the upper stirring blade 32 includes a rolling-in part 321 opened on the side wall of the upper stirring column 31, and the rolling-in part 321 is in the shape of an inclined protrusion, and a flow-stabilizing part 322 opened on one side of the rolling-in part 321, and the flow-stabilizing part 322 is in the shape of an inclined depression.

[0041] Specifically, when the upper stirring blade 32 rotates counterclockwise, the rolling-in part 321 is in the shape of a protrusion, and the side is inclined upward along the rotation direction, which can stir the waste falling on the surface of the slurry, enabling the waste to quickly enter the slurry for fusion and stirring. And during the rotation process, the part of the slurry where the rolling-in part 321 rotates will be in a depressed shape, facilitating the waste to come into contact with and mix with the slurry as soon as it falls, and also preventing the accumulation of a large amount of waste on the surface of the slurry. The flow-stabilizing part 322 is used to stabilize the flow direction of the slurry formed by the stirring of the lower stirring assembly 5 during rotation.

[0042] Referring to 6, the support assembly 4 includes four support rods 41 fixedly connected in a circular array in the middle of the shredding box 1, a support column 42 fixedly connected to the bottom of the support rod 41, and the bottom of the upper stirring column 31 is rotatably connected to the support column 42.

[0043] Specifically, the support assembly 4 is used to support the stirring of the upper stirring assembly 3 and the lower stirring assembly 5. During stirring, the upper stirring column 31 and the lower stirring column 52 rotate inside the support column 42, which can improve the stability of rotation and further improve the stability during the pulping and stirring process.

[0044] Referring to Figures 1 - 7, the lower stirring assembly 5 includes a stirring motor 51 fixedly connected to the bottom of the crushing box body 1, a lower stirring column 52 fixedly connected to the top of the output shaft of the stirring motor 51, the top of the lower stirring column 52 is rotatably connected to the support column 42, and lower stirring blades 53 fixedly connected to the side wall of the lower stirring column 52 in an annular array, and the lower stirring blades 53 are hook-shaped.

[0045] Specifically, when the lower stirring assembly 5 works, the stirring motor 51 rotates to drive the lower stirring column 52 to rotate, and the lower stirring column 52 drives the lower stirring blades 53 to rotate, so that the lower stirring blades 53 further stir the waste materials that have been stirred into the slurry by the upper stirring blades 32. The hook-shaped lower stirring blades 53 can push the slurry entering the bottom upward to the upper part of the crushing box body 1 during stirring, so that the slurry can circulate in the crushing box body 1, accelerating the circulation of the slurry during stirring, and further accelerating the stirring speed of the falling waste materials involved.

[0046] Refer to Figures 1 - 8 , the lower stirring blade 53 includes a pushing part 531 opened on the bottom side wall of the lower stirring column 52, a flowing part 532 opened on one side of the pushing part 531, and a circulating part 533 opened on one side of the flowing part 532.

[0047] Specifically, when the lower stirring blade 53 rotates, the pushing part 531 forms a vortex at the bottom of the slurry, so that the waste materials in the upper part of the slurry can flow downward, and stir the waste materials flowing into the bottom of the slurry. During the stirring process, the pushing part 531 pushes the waste materials to rotate at the bottom of the crushing box body 1, and makes the waste materials flow along the flowing part 532 to the circulating part 533. The circulating part 533 pushes the flowing waste materials upward, so that the waste materials can flow to the upper part of the slurry after being stirred into a paste-like state, forming a cycle. And the steady flow part 322 on the upper stirring blade 32 can steady the slurry flowing upward pushed by the circulating part 533, avoiding excessive agitation of the internal slurry caused by the too high agitation speed of the lower stirring blade 53, resulting in splashing, and can also push the circulated slurry to the middle part of the upper stirring blade 32 again, that is, the middle position at the top of the slurry, so that the slurry can form a complete cycle from top to bottom in the whole crushing box body 1, that is, improving the overall stirring and mixing efficiency of the slurry, and also accelerating the speed of the waste materials participating in the stirring and pulping after just falling.

[0048] Refer to Figure 8 , the pushing part 531 is in the shape of an inclined protrusion, the flowing part 532 is in the shape of a twisted depression, and the circulating part 533 is in an inclined deflection shape in the vertical direction.

[0049] Specifically, the convex pushing part 531 can form a rotating eddy current at the bottom to push and stir the waste materials falling to the bottom. The concave and pipeline-shaped flowing part 532 is used to push the slurry agitated by the pushing part 531 during rotation, so that the slurry can flow from the middle to the side. Furthermore, the circulating part 533 can push the slurry flowing to the side upward to form a cycle. The deflected shape can not only realize the upward pushing cycle of the slurry, but also avoid excessive resistance when the circulating part 533 rotates, causing violent up and down turning of the slurry, thus improving the stability during the pulping process.

[0050] Embodiment 2, refer to Figures 1 - 9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the pulping unit further includes a differential component installed inside the support column 42. The differential component includes a differential assembly 6 installed between the upper stirring column 31 and the lower stirring column 52, and a reset assembly 7 installed above the differential assembly 6 on the upper stirring column 31; the differential assembly 6 includes a driving block 61 fixedly connected to one side of the top of the lower stirring column 52, a rotating groove 62 opened on one side of the bottom of the upper stirring column 31, a driven block 63 fixedly connected to one side of the rotating groove 62, and the driving block 61 is slidably connected in the rotating groove 62, a sliding groove 64 opened on the top of the lower stirring column 52, and the bottom of the upper stirring column 31 is rotatably connected to the sliding groove 64, symmetrically fixedly connected limiting rods 65 on both sides of the bottom of the upper stirring column 31, and a limiting groove 66 opened on the inner wall of the support column 42; the limiting groove 66 includes an annular groove 661 opened on the inner wall of the support column 42, and the annular groove 661 is horizontal, a jacking groove 662 opened on one side of the annular groove 661, a moving groove 663 opened on one side of the jacking groove 662, and a falling groove 664 opened on one side of the moving groove 663, and the annular groove 661, the jacking groove 662, the moving groove 663 and the falling groove 664 are connected end to end in sequence to form a complete ring, and both limiting rods 65 are slidably connected in the limiting groove 66.

[0051] Specifically, the differential component is used to achieve the differentiation of the rotational stirring speeds of the upper stirring component 3 and the lower stirring component 5, such that the rotational speed of the lower stirring component 5 is faster than that of the upper stirring component 3. As a result, the waste materials being stirred at the upper stirring component 3 can be quickly pushed downward. Since the pressure is lower where the flow rate is greater, the pressure of the slurry at the lower stirring component 5 will be lower than that at the upper stirring component 3. That is, when the stirrer is operating, first the upper stirring component 3 will push the slurry forward, and then it will be subjected to the secondary stirring action of the lower stirring component 5. During the downward flow of the slurry from top to bottom, the speed of the lower stirring component 5 is much higher than that of the upper stirring component 3, which results in the pressure around the lower stirring component 5 being much lower than the pressure around the upper stirring component 3. Therefore, during the stirring process, there will be a significant pressure difference between the upper and lower parts. Since the pressure around the lower stirring component 5 is relatively low, the slurry will flow downward under the action of gravity and will ultimately be caught by the lower stirring component 5. Under the stirring action of the lower stirring component 5, the slurry is evenly mixed to form the required slurry. The lower stirring component 5 has a fast stirring speed and can quickly stir the slurry evenly, improving the mixing efficiency and shortening the production cycle.

[0052] During specific operation, the rotation of the lower stirring column 52 drives the rotation of the driving block 61. The driving block 61 will abut against the driven block 63 during rotation, thereby driving the rotation of the upper stirring column 31 through the driven block 63. During the rotation of the upper stirring column 31, the limiting rods 65 on both sides will rotate within the limiting slots 66. The limiting rods 65 will first rotate within the annular slot 661. At this time, the lower stirring column 52 and the upper stirring column 31 rotate synchronously. When the limiting rod 65 moves to the lifting slot 662, the limiting rod 65 will drive the upper stirring column 31 to move upward. When the limiting rod 65 reaches the moving slot 663, at this time the driving block 61 disengages from abutting against the driven block 63, and at this time the driving block 61 no longer drives the driven block 63 to rotate, that is, the lower stirring column 52 no longer drives the upper stirring column 31 to rotate synchronously. The top of the driving block 61 is slidably connected to the bottom of the driven block 63. When the limiting rod 65 moves to the falling-back slot 664, the driving block 61 disengages from abutting against the bottom of the driven block 63, causing the upper stirring column 31 to start to reset and move downward under the action of the reset component 7. At this time, the limiting rod 65 is located at the bottom of the falling-back slot 664, and the lower stirring column 52 continues to drive the driving block 61 to rotate another full circle. When it abuts against the driven block 63 again, it drives the driven block 63 to move along the annular slot 661 to the moving slot 663. In this way, the above cycle is completed, such that when the lower stirring column 52 rotates two circles, it can drive the upper stirring column 31 to rotate one circle, that is, the rotational speed of the lower stirring component 5 is twice that of the upper stirring component 3, achieving a faster stirring speed of the lower stirring component 5 at the bottom than that of the upper stirring component 3, thereby forming a pressure difference between the upper and lower slurries, enabling the slurry at the top to be quickly sucked to the bottom, accelerating the entrainment and mixing of the just-dropped waste materials, and improving the mixing efficiency. The two limiting rods 65 are used to improve the stability of the upper stirring component 3 during rotation.

[0053] Reference Figures 1 - 10 The reset assembly 7 includes a reset groove 71 opened on the inner wall of the support column 42 and located at the top of the limiting groove 66, a reset plate 72 slidably connected in the reset groove 71, and the middle part of the reset plate 72 is fixedly connected to the upper stirring column 31, and a reset member 73 sleeved on the upper stirring column 31, and the two ends of the reset member 73 are respectively fixedly connected to the reset plate 72 and the bottom of the reset groove 71.

[0054] Specifically, the reset component 7 is used to realize the automatic reset of the upper stirring component 3 after being lifted up. When the upper stirring column 31 is lifted up, the reset member 73 is stretched. The reset member 73 can be a spring. When the top of the driving block 61 no longer abuts the bottom of the driven block 63, that is, the upper stirring column 31 is no longer subjected to the extrusion force, the reset member 73 needs to be reset and shortened, driving the entire upper stirring column 31 to move downward, preparing for the subsequent driving block 61 to be abutted and rotated again, thereby realizing differential rotation. The remaining structure is the same as that of Example 1.

[0055] In summary, the working principle of the present invention is as follows: the corrugated paper waste is torn and crushed by the crushing unit 2, so that the crushed waste directly falls into the crushing box 1, the stirring motor 51 rotates to drive the lower stirring column 52 to rotate, thereby driving the lower stirring blade 53 to rotate, the lower stirring column 52 drives the driving block 61 to rotate, and the driving block 61 will resist the driven block 63 during the rotation process, thereby synchronously driving the upper stirring column 31 to rotate, the upper stirring column 31 drives the upper stirring blade 32 to rotate, and the upper stirring column 31 synchronously drives the lower stirring blade 32 to rotate during the rotation process. The limiting rod 65 rotates in the limiting groove 66. When the limiting rod 65 moves to the moving groove 663, the upper stirring column 31 will be lifted up, thereby driving the driven block 63 to gradually disengage from the abutment of the driving block 61. When it is completely disengaged, the driving block 61 will no longer drive the driven block 63 to rotate. After the driving block 61 rotates one more circle, it abuts against the driven block 63 again, causing it to rotate one circle in the annular groove 661, thereby achieving a rotation speed of the lower stirring component 5 that is faster than the upper stirring component 3, thereby achieving rapid involvement of waste in mixed pulping and improving pulping efficiency.
