Description

Technical Field

[0001] This invention belongs to the field of solid waste recycling technology, specifically referring to a fiberboard waste recycling device. Background Technology

[0002] In the field of high-density fiberboard waste recycling, the current common practice is to use crushing equipment to process waste into fine particles. These particles can then be mixed with fiber raw materials and reformed into high-density fiberboard through a high-temperature and high-pressure process, thereby achieving the goal of waste resource utilization.

[0003] However, in the actual recycling process, the waste generated from cutting high-density fiberboard varies significantly in form, covering different specifications of strips and materials of different weights. Such waste is difficult to directly meet the processing conditions of crushing equipment. On the one hand, it is constrained by the internal space of the equipment, and on the other hand, it is affected by the working principle of multi-roller collaborative crushing. Existing crushing processes are more effective at processing small pieces of uniform size. When faced with waste of larger size and weight, the processing efficiency is often low and the equipment is not adaptable enough. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to process fiberboard waste of different qualities and provide a fiberboard waste recycling device to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by the present invention is as follows: A fiberboard waste recycling device includes a multi-component material distribution assembly and a first crushing assembly, wherein each of the material distribution assemblies is disposed in the inner cavity of the first crushing assembly.

[0006] Furthermore, each of the material distribution components includes a material placement plate, which is movably disposed in the inner cavity of the first crushing component via second rotating shafts at both ends.

[0007] Furthermore, a sorting plate is formed inside the material placement plate, and one side of the sorting plate is rotatably connected to the material placement plate via a first rotating shaft. The sorting plate is used to discharge heavy fiberboard waste.

[0008] Furthermore, the other two ends of the material distribution plate are movably connected by curved sliding columns. A spring is sleeved on the outside of the curved sliding column, and the bottom of the spring is connected to the material distribution plate. The spring is configured to restrict the rotation of the material distribution plate.

[0009] Furthermore, the material distribution assembly also includes a discharge plate.

[0010] Furthermore, the discharge plate is disposed on the outside of the placement plate, and the discharge plate is used to discharge small-weight fiberboard waste.

[0011] Furthermore, the material distribution assembly also includes a third rotating shaft, a counterweight, and a baffle plate.

[0012] Furthermore, a third rotating shaft is provided at the lower part of the discharge plate, and a counterweight is sleeved on the outside of the third rotating shaft. The counterweight is used to restrict the rotation of the material plate in the inner cavity of the first crushing component, and a baffle plate is provided at the lower part of the counterweight.

[0013] Furthermore, the material distribution assembly also includes a fixed shaft, a connecting frame, a fixed block, and a connecting column.

[0014] Furthermore, each of the curved sliding columns is provided with a fixed shaft at its bottom, and a connecting frame is connected to the outside of the fixed shaft. The upper part of the connecting frame is connected to the lower part of the material placement plate. The fixing block is provided on both sides of the material distribution plate and is connected to the spring. The top of the curved sliding column is provided with a connecting column, which is fixed to the upper part of the material placement plate. The connecting column is used to fix the curved sliding column.

[0015] Furthermore, the material distribution assembly also includes a baffle and an extension plate.

[0016] Furthermore, the baffle is disposed on the upper side of the material placement plate, and the extension plate is disposed at one end of the material distribution plate. Both the baffle and the extension plate are used to restrict the movement of fiberboard waste.

[0017] Furthermore, the first crushing component includes a feed channel and a partition plate.

[0018] Furthermore, the feed channel is provided with a partition plate inside, which divides the feed channel into two cavities. The partition plate is provided with multiple sets of mounting slots inside, and the material distribution component is movably disposed inside the mounting slots.

[0019] Furthermore, the first crushing assembly also includes a material conveying channel, a first motor, and a first crushing shaft.

[0020] Furthermore, the conveying channel is located at the lower part of the feeding channel, and the first crushing shaft is located inside the conveying channel. The first crushing shaft is used to crush heavy fiberboard waste. A first motor is connected to the outside of the first crushing shaft, and the first motor is used to drive the first crushing shaft to rotate.

[0021] Furthermore, the fiberboard waste recycling device proposed in this invention includes a second crushing component, which is disposed below the first crushing component.

They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment of the invention proposes a fiberboard waste recycling device, including a multi-component material distribution assembly 1 and a first crushing assembly 2. Each of the material distribution assemblies 1 includes a material placement plate 11, a baffle 12, a placement trough 13, a first rotating shaft 14, a material distribution plate 15, an extension plate 16, a curved sliding column 17, a spring 18, a fixed shaft 19, a connecting frame 110, a fixed block 111, a connecting column 112, a second rotating shaft 113, a discharge plate 114, a third rotating shaft 115, a counterweight 116, and a baffle 117.

[0031] The first crushing component 2 includes a feed channel 21, a partition plate 22, a material guard plate 23, a mounting groove 24, a conveying channel 25, a transmission belt 26, a connecting shaft 27, a first motor 28, a support plate 29, and a first crushing shaft 210.

[0032] In embodiments of the present invention, such as Figure 5 and Figure 6 As shown, multiple sets of mounting slots 24 are provided inside the partition plate 22. Each mounting slot 24 is equipped with a material distribution component 1. A placement slot 13 is opened inside the placement plate 11. The size of the placement plate 11 is basically the same as the size of one of the cavities of the feed channel 21. A material distribution plate 15 is provided inside the placement slot 13. One end of the material distribution plate 15 is connected to a first rotating shaft 14. The first rotating shaft 14 is installed inside the placement plate 11. The material distribution plate 15 can be rotated along the first rotating shaft 14 by the action of the first rotating shaft 14. The size of the material distribution plate 15 is also basically the same as the size of the placement slot 13. Therefore, when the uppermost part of the material distribution plate 15 is at the same level as the uppermost part of the placement plate 11, the material distribution plate 15 can block the placement slot 13. A baffle 12 is provided on the upper part of the placement plate 11 to prevent the overflow of fiberboard waste.

[0033] Fixed blocks 111 are attached to both ends of the bottom of the other side of the distribution plate 15. The outer side of the fixed blocks 111 is fixed to the bottom of the spring 18. The spring 18 is sleeved on the outside of the curved sliding column 17. That is, when the distribution plate 15 rotates around the first rotating axis 14, the bottom of the distribution plate 15 can pull the spring 18 along the direction of the curved sliding column 17 through the fixed blocks 111. The top of the curved sliding column 17 is fixed to the upper surface of the placement plate 11 through the connecting column 112. In the initial position, the spring 18 is at the upper part of the placement plate 11. At this time, the upper surfaces of the distribution plate 15 and the placement plate 11 are on the same horizontal plane. When the waste enters the distribution plate 15, the distribution plate 15 is pressed down by gravity. When the weight of the waste is large, the spring 18 can be pulled to make the distribution plate 15 rotate along the first rotating axis 14. Then the waste will enter the first crushing shaft from the extension plate 16 on one side of the distribution plate 15. In the upper cavity of 210, the entire material placement plate 11 is located on one side of the partition plate 22. A discharge plate 114 is connected to one end of the material placement plate 11. The discharge plate 114 can transport lighter waste materials. The discharge plate 114 is located on the other side of the partition plate 22. The two sides of the partition plate 22 handle waste materials of different weights respectively. The two ends of the material placement plate 11 are connected to the second rotating shaft 113. The second rotating shaft 113 is connected to the inside of the mounting groove 24. The material placement plate 11 can rotate around the second rotating shaft 113 inside the mounting groove 24. A third rotating shaft 115 is provided at the lower part of the discharge plate 114. The third rotating shaft 115 is movably connected to the discharge plate 114. A counterweight 116 is also movably provided in the middle of the third rotating shaft 115. The counterweight 116 can rotate along the axis of the third rotating shaft 115. A baffle plate 117 is connected at the lower part of the counterweight 116. The baffle plate 117 can prevent the movement of waste materials.

[0034] like Figure 5 and Figure 6As shown, in the initial position, due to the pulling action of the counterweight 116 on the feeding plate 11, the feeding plate 11 will be tilted. All waste generated during the fiberboard production process first enters the upper part of the feeding plate 11. If the waste is too light to pull the spring 18, it will pass through the discharge plate 114 and the mounting groove 24 into the cavity where the counterweight 116 is located. The baffle plate 117 can prevent the waste from entering other cavities. If the waste is too heavy, its own weight can press the spring 18 downward. At this time, the distribution plate 15 moves along the first rotation axis 1. 4. Rotating downwards, the waste material can enter the cavity below the material distribution plate 15 as the material distribution plate 15 rotates. By applying different degrees of stretching to the material distribution plate 15 with different weights, the waste material generated during the fiberboard production process can be classified. By crushing and pre-treating the heavier waste material, the waste material that finally enters the second crushing component 3 can be small pieces that are easy to process, which greatly improves the efficiency and quality of crushing, avoids the problem of large pieces of material entering the second crushing component 3, and saves the step of removing large pieces of waste material and crushing them again.

[0035] A protective plate 23 is provided outside the feed channel 21. The protective plate 23 is located on the upper part of the distribution plate 15. The cavity where the distribution plate 15 is located is close to the conveyor belt 41 in the feeding assembly 4. The waste material conveyed from the conveyor belt 41 will first enter the upper part of the distribution plate 15. The protective plate 23 can prevent the waste material from splashing. A conveying channel 25 is connected to the lower part of the feed channel 21. Multiple sets of first crushing shafts 210 are arranged inside one cavity of the conveying channel 25. The first crushing shafts 210 are located on the lower part of the distribution plate 15. Connecting rods are provided outside the first crushing shafts 210. Connecting shaft 27, and each connecting shaft 27 is connected to the other via a transmission belt 26. A first motor 28 is connected to the outside of the connecting shaft 27. The first motor 28 can drive the first crushing shaft 210 to rotate, thereby crushing the larger waste material falling from the top of the first crushing shaft 210. The first motor 28 is fixed to the outside of the conveying channel 25 via a support plate 29. The conveying channel 25 is installed above the feed inlet 31. Finally, the large material crushed by the first crushing shaft 210 and the small material screened by the material separating component 1 will enter the feed inlet 31.

[0036] like Figure 1 , Figure 8 and Figure 9 As shown, this embodiment of the invention proposes a fiberboard waste recycling device, including a second crushing component 3, which is disposed below the first crushing component 2. The second crushing component 3 is used to crush small-weight waste materials and waste materials processed by the first crushing shaft 210.

[0037] The feeding component 4 is disposed outside the material distribution component 1 and is used to feed the waste generated during the fiberboard production process to the material distribution component 1.

[0038] The second crushing component 3 includes a feed inlet 31, a second crushing shaft 32, a crushing chamber 33, a second motor 34, and a discharge outlet 35.

[0039] The feeding assembly 4 includes a conveyor belt 41, a spacer plate 42, vertical bars 43, a scraper 44, a third motor 45, a base 46, a transmission device 47, and a main shaft 48.

[0040] In this embodiment of the invention, the upper part of the feed inlet 31 is connected to the conveying channel 25, and the lower part of the feed inlet 31 is provided with a second crushing shaft 32. The second crushing shaft 32 is located inside the crushing chamber 33. The waste material entering the crushing chamber 33 from the feed inlet 31 will eventually be completely crushed by the second crushing shaft 32. The second crushing shaft 32 is driven by a second motor 34 located on its side. Finally, the completely crushed waste material is discharged from the discharge port 35 at the lower part of the crushing chamber 33 for subsequent recycling.

[0041] In this embodiment of the invention, multiple sets of partition plates 42 are provided on the surface of the conveyor belt 41, and the partition plates 42 are arranged at equal intervals. Vertical strips 43 are provided at both ends of the partition plates 42, and scrapers 44 are connected between the vertical strips 43. The scrapers 44 are close to the outside of the partition plates 42 and can move up and down along the inside of the vertical strips 43. During the process of conveying waste by the conveyor belt 41, the scrapers 44 are at the bottom of the partition plates 42 due to gravity. When the conveyor belt 41 drives the partition plates 42 to one end, the partition plates 42 discharge the waste stored therein to the position of the material guard plate 23. At this time, the partition plates 42 are in an inclined state, and the scrapers 44 will move outward of the partition plates 42 due to gravity. With the movement of the scrapers 44, the waste residue adhering to the surface of the partition plates 42 can be scraped away, preventing the waste from accumulating on the inside of the partition plates 42, thereby improving the conveying capacity of the conveyor belt 41 for waste.

[0042] One end of the conveyor belt 41 is connected to the main shaft 48. The outer side of the main shaft 48 is connected to the third motor 45 through the transmission device 47. The third motor 45 can drive the transmission device 47 to move and thus drive the main shaft 48 to rotate, so as to complete the conveying of the conveyor belt 41. The lower part of the conveyor belt 41 is provided with a base 46, which can support the operation of the feeding assembly 4.

[0043] In existing technologies, recycling fiberboard waste typically requires crushing it into fine particles using pulverizing equipment. These particles are then incorporated into high-density fiberboard (HDF) production and subjected to high-temperature and pressure molding, thus enabling waste reuse. However, the diverse shapes and weights of waste generated from HDF cutting make it difficult to directly adapt to the processing requirements of pulverizing equipment. Due to space limitations within the equipment and the multi-roller synergistic crushing principle, existing pulverizing processes are more suitable for processing small, uniformly sized boards, while exhibiting low processing efficiency and poor adaptability for waste of mixed sizes and shapes. This invention addresses this by using a multi-component material processing assembly 1 to classify and process waste in stages. Larger waste is initially crushed by the first pulverizing shaft 210, while the waste entering the second pulverizing assembly 3 consists entirely of smaller, lighter pieces. This improves the crushing efficiency of the second pulverizing assembly 3 on fiberboard waste, eliminates the need for removing and crushing large waste, and saves recycling time.
