Description

Technical Field

[0001] The present invention belongs to the technical field of loose material compaction, and particularly relates to a press for recycling loose materials. Background Art

[0002] The sawdust after sawing has a wide range of uses and can be recycled to make artificial boards, fertilizers, livestock bedding, etc. However, the sawdust is loose in texture, which is very troublesome for transportation and handling. When stacked, due to its looseness, it has a large volume and is not easy to stack vertically. To avoid the above problems, the sawdust needs to be piled up and compacted, so a press is required. The principle of the press is to use extremely high pressure to squeeze the sawdust particles together. Under the action of high pressure, the sawdust particles will undergo plastic deformation, and their limiting structures will intersect and compact with each other to form a tight whole. This process does not require an additional bonding machine and high temperature. By the extrusion of the mold, high pressure is evenly applied to the sawdust, thereby realizing the extrusion of the sawdust into blocks.

[0003] It is found that the publication (announcement) number: CN03808826.6 discloses a press for loose materials, and this technology discloses "including two rollers arranged in a plane, driven in reverse and supported on a frame. At least one of the two rollers" and other technical solutions, and has technical effects such as convenient disassembly and assembly.

[0004] However, after the sawdust is pressed into blocks, due to different requirements (for example, when used as fertilizer or livestock bedding), it needs to be disassembled and used. Therefore, the sawdust cannot be pressed into a whole, resulting in unmerged sawdust on the surface of the pressed sawdust sheet. After the existing press presses the sawdust into sheets, it is not convenient to turn over the sawdust sheets, so it is not easy to clean the unmerged sawdust remaining on the surface of the sawdust sheets. The remaining sawdust not only wastes materials but also is inconvenient for the next filling process.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] As Figure 1 shown;

[0033] Furthermore:

[0034] As Figures 1 to 8 shown;

[0035] Combined with the above content:

[0036] In order to comprehensively clean the debris on the surface of the wood chips, this press for recycling loose materials includes a tablet pressing assembly 1. The tablet pressing assembly 1 includes a pressing shell 11. Inside the pressing shell 11, a screening component 2 is provided, and inside the pressing shell 11, a material cutting component 3 is provided. On the surface of the pressing shell 11, a circulating component 4 is provided;

[0037] Inside the pressing shell 11, a screening plate A21 is provided. The screening plate A21 is inclined. Below the screening plate A21, a screening plate B24 is provided. The inclination direction of the screening plate B24 is opposite to that of the screening plate A21. One end of the screening plate A21 is fixedly connected to a limiting plate A22. The limiting plate A22 is in a convex arc structure. One end of the screening plate B24 close to the limiting plate A22 is fixedly connected to a limiting plate B23. The limiting plate B23 is located on the side of the limiting plate A22 away from the screening plate A21, and the concave surface of the limiting plate B23 faces the limiting plate A22.

[0038] In this embodiment: The wood chips completed by pressing will fall on the surface of the screening plate A21 through the internal components of the tablet pressing assembly 1. The debris on the bottom surface of the wood chips will leak downward through the screening plate A21. Due to the inclined setting of the screening plate A21, the wood chips will slide towards the lower side of the screening plate A21. During the sliding process, the screening plate A21 will exert a certain friction on the wood chips, so that the bottom surface of the screening plate A21 can be cleaned. Until the wood chips enter between the limiting plate A22 and the limiting plate B23, through the limiting of the wood chips by the limiting plate A22 and the limiting plate B23, when the wood chips fall on the surface of the screening plate B24, they have been turned over, so that the top surface of the wood chips becomes the bottom surface, thus the debris on both sides of the wood chips can be cleaned, and the comprehensive cleaning of the wood chips is realized. The cleaned wood chips will be discharged through the screening plate B24.

[0039] Even further:

[0040] In an alternative embodiment, a material feeding shell 12 is fixedly connected to the surface of the pressing shell 11, a tablet pressing shell 13 is fixedly connected to the inner wall of the pressing shell 11, a motor A 19 is installed on the surface of the pressing shell 11 through a mounting seat A, the output shaft of the motor A 19 penetrates through the pressing shell 11 and is rotatably connected to the tablet pressing shell 13. A pressing block roller 14 is arranged inside the tablet pressing shell 13, a positioning shaft 16 is fixedly connected to the surface of the pressing block roller 14, the positioning shaft 16 is fixedly connected to the pressing block roller 14, and the positioning shaft 16 and the pressing block roller 14 are not on the same axis, so that the pressing block roller 14 can move up and down while rotating, and can pound the wood chips, so that the wood chips are bonded to each other under the pounding pressure. A plurality of tooth-shaped structures are arranged on the surface of the pressing block roller 14, and the tooth-shaped structures on the surface of the pressing block roller 14 can increase the contact area with the wood chips.

[0041] In this embodiment: When it is necessary to press the wood chips, the wood chips are poured into the inside of the pressing shell 11 through the material feeding shell 12. At the same time, the motor A 19 is connected to an external power supply and then started. The output shaft of the motor A 19 will drive the positioning shaft 16 to rotate. When the positioning shaft 16 rotates, it will drive the pressing block roller 14 to rotate. The tooth-shaped structures on the surface of the pressing block roller 14 will roll the wood chips entering the inside of the tablet pressing shell 13 downward to the lower part of the pressing block roller 14. And due to the eccentricity of the positioning shaft 16, the wood chips below the pressing block roller 14 will be extruded, so that the wood chips are extruded into blocks.

[0042] Furthermore:

[0043] In an alternative embodiment, a scraping elastic sheet 15 is fixedly connected to the surface of the tablet pressing shell 13 facing the pressing block roller 14. The self-tenacity of the scraping elastic sheet 15 can make it fit more closely to the surface of the pressing block roller 14.

[0044] In this embodiment: After the pressing block roller 14 extrudes the wood chips, the scraping elastic sheet 15 will scrape off the wood chips stuck inside the tooth-shaped structure of the pressing block roller 14 because it fits closely with the pressing block roller 14, preventing the contact area with the subsequent wood chips from being reduced due to the wood chips being stuck inside the tooth-shaped structure.

[0045] Furthermore:

[0046] In an alternative embodiment, a tablet pressing roller 110 is arranged inside the tablet pressing shell 13. One end of the tablet pressing roller 110 is fixedly connected to a sprocket B 17, and a sprocket A 111 is fixedly connected to the surface of the output shaft of the motor A 19. A chain A 18 is sleeved on the surfaces of the sprocket A 111 and the sprocket B 17 and is meshed with them.

[0047] In this embodiment: When the briquetting roller 14 conveys the extruded material backward, the sprocket A111 drives the sprocket B17 to rotate through the chain A18. The rotation of the sprocket B17 drives the tablet pressing roller 110 to rotate. The wood chips conveyed by the briquetting roller 14 towards the tablet pressing roller 110 will be re-extruded due to the mutual clearance between the tablet pressing roller 110 and the tablet pressing shell 13. While making the wood chips in the briquette be extruded more tightly, it can also make the wood chip tablets have the same thickness, which is convenient for subsequent packaging. Also, due to the rotation of the tablet pressing roller 110, the extruded wood chip tablets are conveyed backward.

[0048] Furthermore:

[0049] In an alternative embodiment, a linkage plate 29 is fixedly connected to the surface of the limiting plate B23. A chute A212 is formed in the bottom surface of the tablet pressing shell 13. The linkage plate 29 is slidably connected to the tablet pressing shell 13 through the chute A212. A positioning block 211 is fixedly connected to the surface of the linkage plate 29. A bidirectional screw 210 is threadedly connected inside the positioning block 211. A fixed rod A is fixedly connected to the surface of the bidirectional screw 210. A sprocket C28 is fixedly connected to the surface of the fixed rod A. A chain B27 is meshed with the surface of the sprocket C28. One side of the chain B27 away from the sprocket C28 is sleeved on the surface of the sprocket A111 and meshed with it. A limiting groove 218 is formed inside the limiting plate A22. A toothed plate A213 is arranged on the surface of the limiting groove 218. Both ends of the toothed plate A213 are fixedly connected to the limiting plate B23. A toothed plate B215 is arranged inside the limiting groove 218. The toothed plate B215 is fixedly connected to the limiting plate A22. A gear 214 is arranged inside the limiting groove 218. The gear 214 is meshed with the toothed plate A213 and the toothed plate B215. Two sliders 217 are symmetrically rotatably connected to the surface of the gear 214. A connecting rod 216 is arranged inside the limiting groove 218. Both ends of the connecting rod 216 penetrate through the limiting plate A22 and the limiting plate B23 and are fixedly connected to the pressing shell 11. The slider 217 is fixedly connected to the connecting rod 216.

[0050] In this embodiment: When the sprocket A111 rotates, it drives the sprocket C28 to rotate through the chain B27. The sprocket C28 drives the bidirectional screw 210 to rotate through the fixed rod A. The positioning block 211 that is threadedly connected to the bidirectional screw 210 reciprocates due to being threadedly connected to the bidirectional screw 210. The linkage plate 29 connected to the positioning block 211 is driven to reciprocate inside the chute A212. The limiting plate B23 connected to the linkage plate 29 drives the screening plate B24 to swing back and forth, accelerating the falling speed of the wood chips on the surface of the screening plate B24. When the limiting plate B23 swings, it drives the toothed plate A213 to move inside the limiting groove 218. When the toothed plate A213 moves, it drives the gear 214 meshing with it to rotate inside the slider 217, thereby driving the limiting plate A22 to swing back and forth through the toothed plate B215. Due to the fact that the limiting plate A22 and the screening plate B24 swing in opposite directions each time, the wood chips will not get stuck when entering between the limiting plate A22 and the limiting plate B23.

[0051] Furthermore:

[0052] In an alternative embodiment, a diversion plate 25 is fixedly connected to the surface of the limiting plate A22. The diversion plate 25 is in a triangular structure, and baffle plates 26 are fixedly connected to both sides of the diversion plate 25. Both baffle plates 26 are located outside the screening plate B24.

[0053] In this embodiment: The wood chips falling through the screening plate A21 will land on the surface of the diversion plate 25. Due to the characteristics of the shape of the diversion plate 25, the wood chips will slide into the bottom layer of the pressing shell 11. The two baffle plates 26 are made of rubber. While preventing debris from entering the surface of the screening plate B24, they can also prevent the screening plate B24 from swinging.

[0054] Furthermore:

[0055] In an alternative embodiment, a chute B36 is opened inside the tablet pressing shell 13. A sliding shell 34 is arranged inside the chute B36. The sliding shell 34 is slidably connected to the pressing shell 13 through the chute B36. A limiting rod 33 is slidably connected inside the sliding shell 34. One end of the limiting rod 33 away from the sliding shell 34 is fixedly connected to a fixed rod B. One end of the fixed rod B away from the limiting rod 33 is fixedly connected to a sprocket D32. A chain C31 is meshingly connected to the surface of the sprocket D32. One side of the chain C31 away from the sprocket D32 is meshingly connected to the sprocket B17. A slicing knife 35 is fixedly connected to the surface of the sliding shell 34. The limiting rod 33 is in a Z-shaped structure, so that when the limiting rod 33 rotates around the fixed rod B as the axis, it can drive the sliding shell 34 to slide inside the chute B36.

[0056] In this embodiment: When the sprocket B17 rotates, it will drive the sprocket D32 to rotate through the chain C31. The sprocket D32 will drive the limit rod 33 to rotate through the fixed rod B. The rotation of the limit rod 33 will drive the sliding shell 34 to slide inside the chute B36 due to the shapes of the limit rod 33 and the sliding shell 34 itself. When the sliding shell 34 moves up and down, it will drive the slicing knife 35 to move up and down, thereby cutting off the wood chips, making the specifications of each wood chip the same and facilitating subsequent packaging.

[0057] Furthermore:

[0058] In an alternative embodiment, the recycling assembly 4 includes a linkage shell 41 fixedly connected to the surface of the pressing shell 11. A through groove 44 is formed on the surface of the linkage shell 41 that is connected to the pressing shell 11. A motor B42 is mounted on the surface of the linkage shell 41 through a mounting seat B. A auger 43 is disposed inside the linkage shell 41. The output shaft of the linkage shell 41 penetrates the surface of the linkage shell 41 and is fixedly connected to the auger 43. A feeding pipe 45 is fixedly connected to the surface of the linkage shell 41, and the feeding pipe 45 faces the feeding shell 12.

[0059] In this embodiment: The wood chips entering the bottom of the pressing shell 11 will slide into the inside of the linkage shell 41 through the through groove 44 due to the inclination of the inner wall of the pressing shell 11. Then, connect the motor B42 to an external power source and start it. The auger 43 will rotate inside the linkage shell 41. Due to the characteristics of the shape of the auger 43, the wood chips entering the inside of the linkage shell 41 will be coiled and moved upward until the wood chips are coiled to the feeding pipe 45. The wood chips will enter the inside of the feeding shell 12 again through the feeding pipe 45, realizing re-pressing and forming, thereby realizing the cyclic pressing of the wood chips.

[0060] Working principle and usage process of the present invention: The wood chips completed by pressing will fall on the surface of the screening plate A21 through the internal components of the tablet pressing component 1. The debris on the bottom surface of the wood chips will leak downward through the screening plate A21. Due to the inclined setting of the screening plate A21, the wood chips will slide towards the lower side of the screening plate A21. During the sliding process, the screening plate A21 will apply a certain friction to the wood chips, so as to clean the bottom surface of the screening plate A21 until the wood chips enter between the limiting plate A22 and the limiting plate B23. Through the limitation of the wood chips by the limiting plate A22 and the limiting plate B23, when the wood chips fall on the surface of the screening plate B24, they have been turned over, so that the top surface of the wood chips becomes the bottom surface, thus enabling the cleaning of the debris on both sides of the wood chips, achieving a comprehensive cleaning of the wood chips. The cleaned wood chips will be discharged through the screening plate B24. When it is necessary to press the wood chips, the wood chips are poured into the interior of the pressing shell 11 through the feeding shell 12. At the same time, the motor A19 is connected to an external power supply and then started. The output shaft of the motor A19 will drive the positioning shaft 16 to rotate. When the positioning shaft 16 rotates, it will drive the pressing block roller 14 to rotate. The tooth-shaped structure on the surface of the pressing block roller 14 will roll the wood chips entering the interior of the tablet pressing shell 13 downward. And due to the eccentricity of the positioning shaft 16, the wood chips below the pressing block roller 14 will be extruded, so that the wood chips are extruded into blocks. After the pressing block roller 14 extrudes the wood chips, the scraping elastic piece 15 will scrape off the wood chips stuck inside the tooth-shaped structure of the pressing block roller 14 due to the mutual fitting with the pressing block roller 14, preventing the reduction of the contact area with the subsequent wood chips due to the wood chips being stuck inside the tooth-shaped structure. When the pressing block roller 14 extrudes and conveys the formed wood chips backward, the sprocket A111 will drive the sprocket B17 to rotate through the chain A18. The rotation of the sprocket B17 will drive the pressing roller 110 to rotate. The wood chips conveyed by the pressing block roller 14 towards the pressing roller 110 will be further extruded due to the mutual gap between the pressing roller 110 and the tablet pressing shell 13. While making the wood chip blocks be extruded more tightly, it can also make the wood chips have the same thickness, which is convenient for subsequent packaging. And due to the rotation of the pressing roller 110, the extruded wood chips are conveyed backward. When the sprocket A111 rotates, it will drive the sprocket C28 to rotate through the chain B27. The sprocket C28 will drive the bidirectional screw 210 to rotate through the fixed rod A. The positioning block 211 threadedly connected to the bidirectional screw 210 will reciprocate due to being threadedly connected to the bidirectional screw 210. The linkage plate 29 connected to the positioning block 211 will be driven to reciprocate inside the chute A212. The limiting plate B23 connected to the linkage plate 29 will drive the screening plate B24 to shake back and forth, accelerating the falling speed of the wood chips on the surface of the screening plate B24. When the limiting plate B23 shakes, it will drive the tooth plate A213 to move inside the limiting groove 218. When the tooth plate A213 moves, it will drive the gear 214 meshing with it to rotate inside the slider 217, thereby driving the limiting plate A22 to shake back and forth through the tooth plate B215.Due to the fact that the limiting plate A22 and the screening plate B24 shake in opposite directions each time, the wood chips will not get stuck when entering between the limiting plate A22 and the limiting plate B23. The wood chips falling through the screening plate A21 will land on the surface of the diversion plate 25. Due to the characteristics of the shape of the diversion plate 25, the wood chips will slide into the bottom layer of the pressing shell 11. The two baffle plates 26 are made of rubber. While preventing debris from entering the surface of the screening plate B24, they can also prevent the screening plate B24 from shaking. When the sprocket B17 rotates, it will drive the sprocket D32 to rotate through the chain C31. The sprocket D32 will drive the limiting rod 33 to rotate through the fixed rod B. The rotation of the limiting rod 33 will drive the sliding shell 34 to slide inside the chute B36 due to the shape of itself and the shape of the sliding shell 34. When the sliding shell 34 moves up and down, it will drive the slicing knife 35 to move up and down, thereby cutting off the wood chips, making the specifications of each wood chip the same, which is convenient for subsequent packaging. The wood chips entering the bottom of the pressing shell 11 will slide into the inside of the linkage shell 41 through the through groove 44 due to the inclination of the inner wall of the pressing shell 11. Then, connect the motor B42 to an external power supply and start it. The auger 43 will rotate inside the linkage shell 41. Due to the characteristics of the shape of the auger 43, the wood chips entering the inside of the linkage shell 41 will be coiled and moved upward until the wood chips are coiled to the discharge pipe 45. The wood chips will enter the discharge shell 12 again through the discharge pipe 45, realizing re-pressing and forming, thus realizing the cyclic pressing of the wood chips.
