[0003] In the processing of plant fiber materials (such as straw, hemp, coconut shell fiber, etc.), compression into stacks is often used to facilitate storage and transportation.

[0004] Traditional fiber crushing equipment relies heavily on manual labor or simple machinery, resulting in problems such as low unpacking efficiency, uneven crushing, easy clogging, and discontinuous conveying.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of the present invention; based on the embodiments of the present invention, those skilled in the art can make similar improvements without departing from the spirit of the present invention, but cannot make all other embodiments obtained without creative effort, therefore the present invention is not limited to the specific embodiments disclosed below.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Please see Figures 1 to 28 In order to solve the problems of low crushing efficiency, uneven crushing, easy clogging, discontinuous conveying, low production efficiency and poor equipment stability of traditional fiber crushing equipment, the present invention provides a destacking and feeding device 1000 for plant fiber compressed stacks. The destacking and feeding device 1000 includes a destacking and crushing device 100 and a storage and blowing device 200.

[0026] In one embodiment, the destacking and crushing device 100 includes a conveying mechanism 10, a crushing component (not shown) and a first fan 35; the crushing component includes a scraping mechanism 20 and a crushing mechanism 30, the scraping mechanism 20 is disposed at the end of the conveying mechanism 10 and the crushing mechanism 30 is disposed at the bottom of the scraping mechanism 20.

[0027] In this embodiment, the conveying mechanism 10 transports the fiber compression stack to the scraping mechanism 20, and the fiber compression stack scraped by the scraping mechanism 20 falls into the crushing mechanism 30 for further crushing.

[0028] In one embodiment, the conveying mechanism 10 includes a conveying platform 11, a roller assembly 12 disposed on the conveying platform 11, and a conveyor belt 13 wound around the roller assembly 12. A third sprocket transmission mechanism 27 drives the roller assembly 12 to move the conveyor belt 13.

[0029] Furthermore, the roller assembly 12 includes an active roller 121 and a driven roller 122 respectively disposed at both ends of the conveyor 11. The output end of the third sprocket transmission mechanism 27 is connected to the active roller 121 to drive the active roller 121 to rotate. The rotation of the active roller 121 drives the driven roller 122 to rotate, thereby driving the entire conveyor belt 13 to move, and then smoothly conveying the fiber compression stack placed on the conveyor belt 13 into the scraping mechanism 20.

[0030] Specifically, the speed of the conveyor belt 13 is adjusted by controlling the operating speed of the third sprocket drive mechanism 27, so that the conveying speed of the conveyor belt 13 can match the speed of scraping and crushing.

[0031] In one embodiment, the scraping mechanism 20 includes a scraping housing 21, a drive assembly 22 disposed within the scraping housing 21, and a scraper assembly 23 mounted on the drive assembly 22. The scraping housing 21 has a scraping inlet 211 and a scraping outlet 212 located at the bottom of the scraping housing 21. The conveyor belt 13 conveys the fiber compression stack to the scraping inlet 211. The drive assembly 22 drives the scraper assembly 23 to scrape the fiber compression stack. The scraped-off fibers fall from the scraping outlet 212 into the crushing mechanism 30.

[0032] Furthermore, when the fiber compression stack enters the scraper feed inlet 211, the drive assembly 22 is activated, driving the scraper assembly 23 to scrape the fiber compression stack. The scraper assembly 23 scrapes the fiber compression stack layer by layer, and the scraped fiber fragments fall into the crushing mechanism 30 through the scraper discharge outlet 213 at the bottom of the scraper housing 21 for further processing.

[0033] Specifically, the scraper feed inlet 211 is located on the side of the scraper housing 21. The scraper feed inlet 211 is an opening in the vertical direction. The position of the drive assembly 22 matches the position of the scraper feed inlet 211 so as to drive the scraper assembly 23 to scrape the fiber.

[0034] In one embodiment, the drive assembly 22 is a chain structure, which includes a sprocket shaft assembly 221, a sprocket 222 disposed on the sprocket shaft assembly 221, and a chain 223 wound around the sprocket 222. The scraper assembly 23 is disposed on the chain 223. The chain 223 moves under the drive of the sprocket shaft assembly 221 to drive the scraper assembly 23 to move linearly, thereby scraping the fiber compression stack that enters the scraping feed inlet 211.

[0035] Specifically, the transmission path of the chain 223 is matched with the position of the scraper feed inlet 211, so that the scraper assembly 23 installed on the chain 223 can move in a circular linear motion close to the inner side of the scraper feed inlet 211. When the fiber compression stack is pushed to the scraper feed inlet 211 by the conveying mechanism 10, the moving scraper assembly 23, like a "comb", continuously scrapes the fibers on the surface of the fiber compression stack layer by layer to achieve efficient and continuous destacking, effectively improving the destacking efficiency of the fiber compression stack.

[0036] In one embodiment, multiple sets of sprockets 222 and chains 223 are arranged, with multiple sets of sprockets 222 being parallel and spaced apart on the sprocket shaft group 221. This not only improves the stable operation of the scraper assembly 23, but also ensures the uniformity of the scraping force of the scraper assembly 23.

[0037] When three or more sets of sprockets 222 are mounted parallel and spaced apart on the sprocket shaft assembly 221, correspondingly, three or more sets of chains 223 are wound around the corresponding sprockets 222.

[0038] Specifically, each set of chains 223 is connected in parallel with the scraper assembly 23, so that the scraping mechanism 20 can process fiber compression stacks with a large width at the same time, avoiding the problem of jamming or uneven scraping caused by single-point force, ensuring the stable operation of the de-packing and crushing device 100, and effectively improving the efficiency of the de-packing and crushing device 100 in processing fiber compression stacks.

[0039] In one embodiment, the sprocket shaft assembly 221 includes a first sprocket shaft 2211 disposed at the top of the scraper housing 21 and a second sprocket shaft 2212 disposed at the bottom of the scraper housing 21.

[0040] Furthermore, each set of sprockets 222 includes a driving sprocket 2221 passing through the first sprocket shaft 2211 and a driven sprocket 2222 passing through the second sprocket shaft 2212, with the two ends of the chain 223 respectively meshing with the driving sprocket 2221 and the driven sprocket 2222.

[0041] Specifically, a plurality of driving sprockets 2221 are fixedly mounted on the first sprocket shaft 2211, and a plurality of driven sprockets 2222 are correspondingly fixedly mounted on the second sprocket shaft 2212; the upper end of each chain 223 meshes with a driving sprocket 2221 on the first sprocket shaft 2211, and the lower end of each chain 223 meshes with a corresponding driven sprocket 2222 on the second sprocket shaft 2212, thereby forming a vertically oriented circular transmission circuit.

[0042] In one embodiment, the scraper assembly 23 includes multiple sets of scraper plates 231, each set of scraper plates 231 being equally spaced along the length of the chain 223, each set of scraper plates 231 being perpendicular to the chain 223, and the chain 223 being parallel to the sprocket shaft assembly 221.

[0043] Furthermore, the sprocket shaft assembly 221 is perpendicular to the plane where the chain 223 is located, and the scraper plate 231 is parallel to the sprocket shaft assembly 221 and perpendicular to the chain 223.

[0044] In one embodiment, each set of scraper blades 231 includes a fixed support 2311 fixedly mounted on the chain and a plurality of scrapers 2312 spaced apart on the fixed support 2311.

[0045] Specifically, several scrapers 2312 are spaced apart along the length of the fixed support 2311, and the cutting edge of each scraper 2312 faces the scraping feed port 211, so that when the scraper 2312 passes through the scraping feed port 211, it can scrape the fiber compression stack with the largest contact area and the best force angle.

[0046] In one embodiment, the crushing mechanism 30 includes a crushing chamber 31 and a roller assembly 32 disposed in the crushing chamber 31, the roller assembly 32 being used to crush fallen fibers.

[0047] Furthermore, the crushing chamber 31 is provided with a crushing discharge port 312 and a crushing inlet 311 that matches the scraping discharge port 212.

[0048] Specifically, when the fiber fragments scraped off by the scraper assembly 23 fall into the crushing chamber 31 through the scraper outlet 212 at the bottom of the scraper housing, the roller assembly 32 moves at high speed to further crush the falling fiber fragments, and the crushed fiber fragments are discharged from the crushing outlet 312 on the crushing chamber 31.

[0049] In one embodiment, the roller assembly 32 includes a roller 321 and a plurality of rollers 322 spaced apart on the roller 321. The rollers 322 are used to crush fiber fragments that fall into the crushing chamber 31.

[0050] Specifically, several rollers 322 are fixedly mounted on the roller shaft 321 at a certain angle or radially. When the roller shaft 321 is driven to rotate at high speed, these rollers 322 repeatedly impact, shear and agitate the fiber fragments that fall from the crushing inlet 311 into the crushing chamber 31, thereby further crushing the larger fiber fragments into smaller, compliant fiber fragments.

[0051] Furthermore, the roller assembly 32 also includes several turntables 323 spaced apart along the length of the roller 321 on the roller 321, with the turntables 323 perpendicular to the length of the roller 321; multiple connecting rods 324 parallel to the roller 321 pass through the turntables 323, and several rollers 322 are spaced apart along the length of each connecting rod 324 to prevent fibers from getting tangled on their surfaces.

[0052] Specifically, multiple connecting rods 324 parallel to the roller shaft 321 pass through pre-set holes (not shown) on the turntable 323 and are fixedly connected to the turntable 323 to form a sturdy cage frame; several roller cutters 322 are evenly arranged on the connecting rods 324, so that the roller cutters 322 have stronger crushing force and higher crushing efficiency when rotating at high speed.

[0053] In one embodiment, the crushing chamber 31 includes an upper chamber 313 and a lower chamber 314 connected to the upper chamber 313. The roller cutter assembly 32 is disposed in the upper chamber 313. A plurality of hollowed-out baffles 33 are provided at equal intervals at the top opening of the upper chamber 313, and fiber fragments fall to the roller cutter assembly 32 through the baffles 33.

[0054] By installing several perforated baffles 33 at equal intervals at the top opening of the upper cavity 313 (i.e. the material feed inlet), these baffles 33 form a grid, effectively buffering the falling fiber fragments and preventing the fiber fragments from accumulating directly and in large quantities on the roller cutter assembly 32, thereby achieving uniform feeding and protecting the roller cutter assembly 32.

[0055] Furthermore, the upper cavity 313 and the lower cavity 314 are separated by a screen plate 34, and the crushed material outlet 312 is connected to the lower cavity 314. The fiber crushed by the roller cutter assembly 32 is then discharged from the crushed material outlet 312 through the first blower 35.

[0056] Specifically, by connecting the crushed material outlet 312 to the lower cavity 314, and connecting the first blower 35 at the crushed material outlet 312, the airflow generated by the first blower 35 draws qualified finely crushed fiber material out of the crushed material outlet 312 through the lower cavity 314 and transports it to the storage and blowing device 200, while large pieces of fiber material that fail to pass through the screen plate 34 continue to remain in the upper cavity 313 and are repeatedly crushed, thereby controlling the particle size of the fiber material.

[0057] In one embodiment, the storage and blowing device 200 includes a storage tank 40, an inverted conical connecting seat 50 connected to the bottom of the storage tank 40, a material conveying pipe 60, an air defense mechanism 70, a conveying pipe (not shown), and at least one set of fiber feeding components 80. The conveying pipe is connected between the storage tank 40 and the crushing mechanism 30. A first fan 35 is installed on the conveying pipe to convey the fiber fragments crushed by the crushing mechanism 30 to the storage tank 40 by the wind power of the first fan 35.

[0058] In this embodiment, the fiber fragments in the storage tank 40 fall into the connecting seat 50 and are further crushed. The crushed fiber fragments fall into the material conveying pipe 60 and are then conveyed to the air defense mechanism 70 by the material conveying pipe 60.

[0059] In one embodiment, the storage bin 40 includes a bin body 41 and a cover plate 43. The cover plate 43 covers the top of the bin body 41. A storage inlet 42 is provided on the side of the bin body 41. The bottom of the bin body 41 has an open structure. A conveying pipe (not shown) is connected to the storage inlet 42. The conveying pipe is used to convey the fiber scraps conveyed by the first fan 35 from the storage inlet 42 into the bin body 41.

[0060] Furthermore, the material inlet 42 is located on the side of the barrel 41. The material inlet 42 is a rectangular opening in the horizontal direction (not shown in the figure). In order to further stabilize the material conveying pipe, a triangular prism-shaped fixed support 45 is welded on the outer wall of the barrel 41 at the position of the material inlet 42.

[0061] Specifically, one right-angled surface of the fixed support 45 is attached to the outer wall of the barrel 41, with its inclined surface facing upwards and a circular fixing hole 46 opened on the bottom surface; the outlet section of the conveying pipe passes through this fixing hole 46 and is then inserted into the storage inlet 42, so that the conveying pipe can be tightly connected to the storage inlet 42 through the fixed support 45, thereby enhancing the stability and sealing of the connection between the conveying pipe and the barrel 41 through the fixed support 45.

[0062] The fixed support 45 effectively bears part of the weight of the conveying pipe and the vibration caused by wind conveying, preventing fatigue loosening or leakage at the connection. Thus, the fixed support 45 enhances the stability and sealing of the connection between the conveying pipe and the barrel 41.

[0063] In one embodiment, the storage bin 40 further includes an exhaust vent (not shown) located at the center of the top of the cover plate 43 and an exhaust assembly 44 connected to the exhaust vent.

[0064] Specifically, the exhaust component 44 promptly discharges the air blown into the barrel 41 along with the fiber scraps, thereby maintaining a slightly negative pressure or normal pressure inside the storage barrel 40. This prevents dust from escaping through gaps due to positive pressure and also prevents excessive negative pressure from affecting the feeding air velocity and efficiency.

[0065] Furthermore, the exhaust assembly 44 includes an exhaust duct 441 and a plurality of exhaust openings (not shown) opened on the exhaust duct 441, the exhaust openings being spaced apart along the length of the exhaust duct 441.

[0066] Specifically, the main body of the exhaust pipe 441 is a vertical circular exhaust pipe, with multiple exhaust openings evenly distributed along the length of the exhaust pipe 441. This evenly distributed design with multiple exhaust openings replaces a single large outlet, allowing the exhaust airflow to be dispersed more gently and evenly into the atmosphere. This reduces the disturbance of the settled fiber material layer in the storage bin 40 caused by the turbulence formed by concentrated exhaust, which is beneficial for the stable accumulation of materials in the storage bin 40.

[0067] Furthermore, the exhaust assembly 44 also includes a bag connector 442 and an exhaust bag (not shown in the figure), the bag connector 442 being fixedly connected to the exhaust opening, and the exhaust bag being fixedly connected to the bag connector 442.

[0068] By welding a short tubular bag connector 442 to the outer port of each exhaust opening, and fitting a cylindrical exhaust bag made of non-woven fabric or polyester filter cloth onto each bag connector 442, and securing it with an elastic clamp; the exhaust bag can efficiently filter the fine fiber dust entrained in the exhaust gas to achieve environmentally friendly exhaust.

[0069] Specifically, the exhaust filter bag features a quick-release design, facilitating regular cleaning or replacement and ensuring stable exhaust resistance and long-lasting filtration.

[0070] In one embodiment, the connecting seat 50 includes an inverted conical hollow connecting shell 51, a stirring chamber 52 formed by the connecting shell 51, and a stirring assembly 54 disposed in the stirring chamber 52. The bottom of the stirring chamber 52 is provided with a material storage outlet 53, and the top of the stirring chamber 52 is connected to the bottom of the storage tank 40.

[0071] Specifically, when the fiber fragments in the storage hopper 40 fall into the mixing chamber 52, the mixing component 54 on the mixing chamber 52 further mixes the fiber fragments, and then they fall into the material conveying pipe 60 through the storage outlet 53 at the bottom of the mixing chamber 52 for the next processing step.

[0072] Furthermore, the mixing assembly 54 includes multiple sets of mixing elements 55 arranged laterally along the mixing chamber 52. Each set of mixing elements 55 includes a mixing shaft 551 fixedly connected in the mixing chamber 52 and several mixing blades 552 arranged axially along the mixing shaft 551. The multiple sets of mixing elements 55 are spaced apart in the mixing chamber 52, and each mixing element 55 is parallel to the axis of the mixing chamber 52, so that the mixing element 55 as a whole is parallel to the material conveying pipe 60, thereby achieving uniform mixing and guiding of the material.

[0073] Specifically, the stirring shaft 551 of each set of stirring components 55 extends longitudinally through the stirring chamber 52, and the two ends of the stirring shaft 551 are fixedly mounted on the side wall of the stirring chamber 52 through bearing seats (not shown); the stirring blades 552 of the multiple sets of stirring components 55 are staggered in the axial and circumferential directions of the stirring shaft 551.

[0074] When the stirring shaft 551 and the stirring blade 552 rotate synchronously, they can cut, turn over and guide the falling fiber fragments, thereby effectively preventing the fiber material from becoming loose and clogged in the conical connecting seat 50, and ensuring that the fiber material can fall evenly to the storage outlet 53.

[0075] In one embodiment, the connecting seat 50 includes a cone top 56 with a larger size and a cone bottom 57 with a smaller size. The cone top 56 is connected to the bottom of the barrel 41. The top of the material conveying pipe 60 is provided with a connection port 61, and the cone bottom 57 is connected to the connection port 61. The anti-aircraft mechanism 70 is connected to the end of the material conveying pipe 60. The fiber material falls into the material conveying pipe 60 through the cone bottom 57, and is then conveyed to the anti-aircraft mechanism 70 through the material conveying pipe 60 for the next processing step.

[0076] Specifically, the bottom of the cone 57 is the material outlet 53, which is fixedly connected to the connection port 61.

[0077] In one embodiment, the material conveying pipe 60 is a hollow cylindrical structure, and a conveying component 62 is also provided inside the material conveying pipe 60. The conveying component 62 is used to convey fiber scraps to the air defense mechanism 70.

[0078] Furthermore, the conveying assembly 62 includes a conveying shaft 621 and a spiral conveying plate 622. The conveying shaft 621 passes through the conveying plate 622 so that it can form a spiral feeding channel (not shown) in the material conveying pipe 60, through which the fiber scraps are conveyed to the air defense mechanism 70.

[0079] Specifically, the conveying shaft 621 is coaxially arranged with the material conveying pipe 60, and the outer edge of the conveying plate 622 is close to the inner wall of the material conveying pipe 60, thereby forming a continuous spiral feeding channel in the material conveying pipe 60; when the conveying shaft 621 rotates, the conveying plate 622 pushes the fiber fragments to move along the spiral feeding channel of the material conveying pipe 60 toward the air defense mechanism 70.

[0080] In one embodiment, the air defense mechanism 70 includes an air defense housing 71 and an air defense component 72 disposed within the air defense housing 71. The air defense component 72 is arranged parallel to the material conveying pipe 60. When the material conveying pipe 60 conveys fiber fragments into the air defense housing 71, the air defense component 72 is used to stir the fiber fragments to achieve the air defense effect.

[0081] Furthermore, the air defense component 72 includes a rotating shaft 721 and a number of rotating blades 722 spaced apart on the rotating shaft 721. The rotating blades 722 are used to stir the air defense fiber fragments.

[0082] Specifically, the air defense component 72 is driven by the second drive mechanism 73.

[0083] When the fiber fragments in the material conveying pipe 60 are being conveyed normally, the rotary cutter 722 follows the rotating shaft 721 to idle or rotate at low speed; when there is insufficient material or blockage in the material conveying pipe 60, the second drive mechanism 73 drives the rotary cutter 722 to rotate at high speed to forcibly break up any possible fiber clumps or tangled clumps in order to clear the feeding channel and prevent blockage.

[0084] In one embodiment, each fiber feeding assembly 80 includes a feeding pipe 81 and a second fan 82. The feeding pipe 81 is connected to the outlet of the air raid shelter 71 to convey the fiber fragments agitated by the air raid shelter 72 out by the second fan 82.

[0085] In one embodiment, the storage blowing device 200 further includes a support component 90, which includes a support frame 91, a support platform 92, and a support base 93. The support frame 91 is fixedly connected to the outer side of the barrel 41, and the air defense mechanism 70 is disposed on the support base 93.

[0086] Specifically, the support frame 91 is welded together from four uprights (not shown) and several cross braces (not shown), tightly clamping the outer periphery of the storage tank 40 to provide it with primary support; on one side of the connecting seat 50, a horizontal support platform 92 is welded to the support frame 91; below the end of the material conveying pipe 60, an independent support seat 93 is welded through channel steel to support and fix the relatively heavy air defense mechanism; so that the entire support system is stable and reliable, and the entire support assembly 90 effectively distributes the weight of each piece of equipment and the vibration during operation, thereby ensuring the stable operation of each piece of equipment.

[0087] Furthermore, the storage blowing device 200 also includes a first drive mechanism 58 for driving the stirring shaft 551 of the stirring assembly 54 in the connecting seat 50 to move, and a second drive mechanism 73 for driving the rotating shaft 721 of the air defense assembly 72 in the air defense mechanism 70 to move.

[0088] Specifically, the first drive mechanism 58 is horizontally mounted on the support platform 92, and its output shaft is connected to the input end of the stirring shaft 551 of the stirring assembly 54, thereby driving the stirring shaft 551 to move. The movement of the stirring shaft 551 drives the movement of 552, thereby further crushing the fiber fragments. The second drive mechanism 73 is directly and vertically mounted on the support base 93 next to the air defense mechanism 70, and its output shaft is coaxially and directly connected to the rotating shaft 721 of the air defense assembly 72 through a coupling.

[0089] The first drive mechanism 58 and the second drive mechanism 73 are controlled independently, and the speed of stirring and anti-air crushing can be adjusted according to the specific conditions of the fiber material, thereby achieving precise operation.

[0090] The specific workflow of this invention is as follows: The fiber compression stack is fed into the scraping mechanism 20 via the conveying mechanism 10. The scraper assembly 23 scrapes off the surface fiber, and the fiber fragments fall into the crushing mechanism 30 and are further crushed by the roller assembly 32. Then, the first fan 35 sucks the fiber fragments into the storage tank 40 through the conveying pipe. After being stirred by the stirring assembly 54 in the storage tank 40, the fiber fragments fall into the material conveying pipe 60 through the connecting seat 50, and are then pushed to the air defense mechanism 70 by the spiral conveying assembly 62. Finally, the fiber feeding assembly 80 outputs the fiber fragments by air force.

[0091] Compared with the prior art, the present invention has at least the following technical effects: 1. The present invention provides a destacking and feeding device 1000 for plant fiber compressed stacks, which integrates a destacking and crushing device 100 and a storage and blowing device 200 into one unit, thereby realizing the automation, continuous destacking, crushing, temporary storage and conveying of plant fiber compressed stacks.

[0092] 2. The unpacking and crushing device 100 of the present invention employs a scraping mechanism 20 and a crushing mechanism 30 to scrape and crush the compressed stack layer by layer, and then convey it to the storage tank 40 for temporary storage by wind power.

[0093] 3. The stirring component 54 and the anti-air mechanism 70 in the material storage and blowing device 200 of the present invention effectively prevent the accumulation and bridging of fiber fragments during the conveying process, ensuring continuous, uniform and efficient material conveying.

[0094] 4. The present invention provides a destacking and feeding device 1000 for compressing plant fiber stacks. The device has a compact structure, is easy to operate, and effectively improves production efficiency and material utilization.
