Description

Technical Field

[0001] This invention relates to the field of intelligent packaging equipment technology, and in particular to an anti-bridging spiral unloading hopper device for intelligent packaging. Background Technology

[0002] In industries such as chemical engineering, thermal power generation, and building materials, RDF, straw, paper scraps, and plastic sheets are common biomass fuels. These biomass fuels typically require intelligent packaging during transportation. When using specialized intelligent packaging equipment, these lightweight biomass materials need to be conveyed into the packaging. The usual method is to use a forklift to scoop the material from the stockpile into a hopper, and then a screw conveyor under the hopper transports the material to the subsequent packaging, completing the intelligent packaging process. However, lightweight biomass materials are prone to bridging in the hopper, causing the screw conveyor in the intelligent packaging equipment to idle, preventing continuous material conveying, and leading to blockages that require manual unclogging. This not only reduces production efficiency and causes dust pollution but also poses significant personal safety hazards.

[0003] Currently, common methods to solve the problem of material arching and bridging include mechanical vibration and pneumatic arch breaking. Mechanical vibration involves installing a vibrator on the hopper to loosen and lower the material; pneumatic arch breaking involves introducing compressed air into the hopper to break the arched structure of the material. However, these methods are not very effective for lightweight biomass materials and are almost ineffective. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the mechanical vibration and pneumatic arch breaking methods used for light biomass materials in the storage hopper are not effective and are not easy to break the arch.

A speed regulating roller corresponding to the transmission roller is rotatably mounted on the inner wall of the protective box. An adjusting screw is provided through the inner wall of the protective box at a position between the transmission roller and the speed regulating roller. A guide rod corresponding to the adjusting screw is fixedly mounted on the bracket. An adjusting disc is fitted on the outer wall of the adjusting screw and the guide rod. A speed regulating ring is fitted on the outer wall of the adjusting disc. A shaft is fixedly mounted on the side of one of the rotating seats. The shaft is connected to the speed regulating roller via a driven wheel and a synchronous belt.

[0009] Preferably, both the transmission roller and the speed regulating roller are configured as frustoconical, and the outer wall of the speed regulating ring is in contact with the outer walls of the transmission roller and the speed regulating roller.

[0010] Preferably, the guide structure includes a guide opening on the inner wall of the storage hopper corresponding to the end of the arch-breaking rod, the end of the arch-breaking rod passing through the guide opening and rotatably fitted with a baffle adapted to the guide opening, the baffle being slidably connected to the side of the storage hopper, a transmission gear being fixedly installed at the end of the arch-breaking rod located on the outside of the storage hopper, and a fixed rack meshing with the transmission gear being fixedly installed on the side of the storage hopper.

[0011] Preferably, the inner side of the arch-breaking rod is hollow, a linkage rod is provided inside the arch-breaking rod, and several sets of material-pulling components are arranged in a linear array on the outer wall of the arch-breaking rod.

[0012] Preferably, the feeding assembly includes three mounting ports arranged in a ring array on the outer wall of the arch-breaking rod.

[0015] The technical effects and advantages of this invention are as follows: In this invention, the spiral blades drive the arch-breaking blades to tumble the upper material, while the arch-breaking rod simultaneously performs reciprocating sliding and rotational movements. Combined with the reciprocating rotation of the stirring blades, the material in the storage hopper is stirred and arched in multiple dimensions. Furthermore, when the arch-breaking rod slides, the baffle blocks the guide port to prevent material leakage. These multiple actions ensure that the material is fully stirred and arched, avoiding jamming and ensuring smooth unloading, thus laying the foundation for continuous material supply for intelligent packaging equipment. In this invention, by rotating the adjusting screw to change the position of the speed regulating ring, the reciprocating speed of the arch-breaking rod can be adjusted to meet the processing needs of different light biomass materials. This adjustment mechanism allows the equipment to maintain stable unloading when faced with changes in material characteristics, thus improving the equipment's adaptability to diverse working conditions. In this invention, the coordinated action of the arch-breaking rod and the stirring blade accelerates the unloading speed. The meshing of the transmission gear and the fixed rack causes the arch-breaking rod to rotate, enhancing the arch-breaking effect. The linkage structure drives the stirring blade to rotate, further optimizing the stirring and arch-breaking effect. All components are closely matched, reducing potential failures, ensuring rapid and continuous unloading, maintaining the efficient operation of the intelligent packaging equipment, and improving overall production efficiency.

Detailed Implementation

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figure 1-3As shown, the present invention provides a technical solution: an intelligent packaging anti-bridging spiral unloading hopper device, including a spiral trough 11 and a storage hopper 12 fixedly installed on the top surface of the spiral trough 11. A discharge port 13 is provided at the bottom end of the spiral trough 11. Two spiral blades 14 are rotatably installed on the inner wall of the spiral trough 11. Two reduction motors 15 corresponding to the spiral blades 14 are provided at the end of the spiral trough 11. A coupling 16 is provided between the output end of the reduction motor 15 and the spiral blades 14. Four evenly distributed rotating seats 21 are rotatably installed on the inner wall of the storage hopper 12. Several anti-bridging blades 22 arranged in a ring array are fixedly installed on the outer wall of the rotating seats 21.

[0020] In use, the entire spiral unloading hopper is located at the discharge end of the intelligent packaging equipment. It can be used for intelligent packaging and conveying of light biomass materials. Specifically, the material is unloaded into the storage hopper 12 by a loader or grab bucket. The geared motor 15 is started, which drives the coupling 16 to rotate. The coupling 16 drives the spiral blades 14 to rotate. The rotating spiral blades 14 can push the anti-bridging blades 22 to rotate, turning the material in the storage hopper 12. The upper layer of material in the storage hopper 12 is continuously turned and pushed into the spiral conveyor trough 11 to prevent the material from bridging or arching in the storage hopper 12. At the same time, the rotating spiral blades 14 push the material in the spiral conveyor trough 11 into the discharge port 13 so that the material can be intelligently packaged later.

[0021] Reference Figure 1 and Figure 7 As shown, the inner wall of the storage hopper 12 is provided with an arch-breaking component. The arch-breaking component includes a push shaft 31 that passes through the inner wall of the storage hopper 12. One end of the push shaft 31 is fixedly installed with an installation sleeve 32. An arch-breaking rod 33 is rotatably installed on the inner wall of the installation sleeve 32. The outer wall of the push shaft 31 is fitted with a spring 34, the two ends of which are fixedly connected to the push shaft 31 and the storage hopper 12 respectively. One end of the arch-breaking rod 33 is provided with a guide structure. Reference Figure 3-5 As shown, a linkage component is provided between the arch-breaking component and a rotating seat 21. The linkage component includes a bracket 41 fixedly installed on the side of the storage hopper 12. A rotating shaft 42 is rotatably installed on the inner wall of the bracket 41. A cam 43 corresponding to the push shaft 31 is fixedly fitted on the outer wall of the rotating shaft 42. A driven bevel gear 44 is fixedly fitted on the outer wall of the rotating shaft 42. A protective box 46 corresponding to the bracket 41 is fixedly installed on the side of the storage hopper 12. A drive bevel gear 45 meshing with the driven bevel gear 44 is provided on the inner wall of the protective box 46. A corresponding counterweight box 47 is fixedly installed on the side of the storage hopper 12 at a position symmetrical to the protective box 46. A speed regulating structure is provided between the rotating shaft 42 and the rotating seat 21.

[0022] When the drive bevel gear 45 is driven to rotate, it can drive the rotating shaft 42 to rotate through the driven bevel gear 44. When the rotating shaft 42 rotates, it can drive the cam 43 on it to rotate. During the rotation of the cam 43, the use of the spring 34 can make the push shaft 31 slide back and forth, and drive the arch-breaking rod 33 to move back and forth inside the storage hopper 12 through the mounting sleeve 32.

[0023] Reference Figure 3 and Figure 4 As shown, the speed regulating structure includes a transmission roller 51 rotatably mounted on the inner wall of the protective box 46, with the end of the transmission roller 51 fixedly connected to the side of the drive bevel gear 45. A speed regulating roller 52 corresponding to the transmission roller 51 is rotatably mounted on the inner wall of the protective box 46. Both the transmission roller 51 and the speed regulating roller 52 are truncated cone-shaped. An adjusting screw 53 is provided through the inner wall of the protective box 46 at the position between the transmission roller 51 and the speed regulating roller 52. A guide rod 54 corresponding to the adjusting screw 53 is fixedly mounted on the bracket 41. An adjusting disc 55 is fitted on the outer wall of the adjusting screw 53 and the guide rod 54. A speed regulating ring 56 is fitted on the outer wall of the adjusting disc 55. The outer wall of the speed regulating ring 56 is in contact with the outer walls of the transmission roller 51 and the speed regulating roller 52. A shaft 23 is fixedly mounted on the side of a rotating seat 21. The shaft 23 is connected to the speed regulating roller 52 through a driven wheel and a synchronous belt.

[0024] As the anti-bridging blade 22 rotates with the rotating seat 21, it drives the shaft 23 to rotate synchronously. The rotation of the shaft 23 drives the speed regulating roller 52 to rotate via the driven wheel and synchronous belt. The rotation of the speed regulating roller 52 drives the speed regulating ring 56 to rotate, which in turn drives the transmission roller 51 to rotate. The drive bevel gear 45 is fixedly connected to the end of the transmission roller 51, thus allowing the drive bevel gear 45 to rotate synchronously. When the anti-bridging rod 33 reciprocates, the operator can adjust the reciprocating speed of the anti-bridging rod 33 according to the actual material condition in the storage hopper 12 to ensure normal material unloading and normal operation of the intelligent packaging equipment. Specifically, the operator... The operator can rotate the adjusting screw 53. The adjusting disk 55 is screwed to the adjusting screw 53 and slidably connected to the guide rod 54. Therefore, when the adjusting screw 53 rotates, it can drive the adjusting disk 55 to slide along the guide rod 54, thereby adjusting the position of the adjusting disk 55 and the speed regulating ring 56. Since the transmission roller 51 and the speed regulating roller 52 are both frustoconical and are arranged opposite each other, the speed regulating ring 56 can change the speed ratio between the transmission roller 51 and the speed regulating roller 52 when adjusting the position between them. This allows for the adjustment of the rotation speed of the transmission roller 51, and in turn, the speed of the reciprocating movement of the arch-breaking rod 33 can be adjusted to cope with different materials.

[0025] Reference Figure 1 , Figure 5 and Figure 6As shown, the guide structure includes a guide opening 61 on the inner wall of the storage hopper 12 corresponding to the end of the arch-breaking rod 33. The end of the arch-breaking rod 33 passes through the guide opening 61 and is rotatably fitted with a baffle 62 adapted to the guide opening 61. The baffle 62 is slidably connected to the side of the storage hopper 12. A transmission gear 63 is fixedly installed on the end of the arch-breaking rod 33 located on the outside of the storage hopper 12. A fixed rack 64 that meshes with the transmission gear 63 is fixedly installed on the side of the storage hopper 12.

[0026] During the reciprocating sliding of the arch-breaking rod 33, its end can reciprocate along the guide opening 61. During the sliding process, the baffle 62 can always block the guide opening 61 to prevent material from leaking out of the storage hopper 12. At the same time, the transmission gear 63 can reciprocate along with the arch-breaking rod 33. The transmission gear 63 meshes with the fixed rack 64. Therefore, during the reciprocating sliding process, under the action of the fixed rack 64, the transmission gear 63 and the arch-breaking rod 33 can reciprocate to rotate, so as to stir the material in the storage hopper 12 and further improve the arch-breaking effect.

[0027] Reference Figure 7-9 As shown, the inner side of the arch-breaking rod 33 is hollow, and a linkage rod 71 is installed inside the arch-breaking rod 33. The outer wall of the arch-breaking rod 33 is provided with several sets of material-feeding components arranged in a linear array. The material-feeding components include three mounting ports 74 arranged in a ring array on the outer wall of the arch-breaking rod 33. A rotating plate 75 is rotatably installed on the inner wall of the mounting port 74. A stirring blade 76 is fixedly installed on the outer wall of the rotating plate 75. A connecting telescopic rod 77 is provided between the rotating plate 75 and the linkage rod 71. The fixed end of the connecting telescopic rod 77 is connected to the linkage rod 71. The outer wall is fixedly connected, and the telescopic end of the telescopic rod 77 is hinged to the outer wall of the rotating plate 75. A fixed sleeve 72 is fixedly installed on the inner wall of the end of the arch-breaking rod 33 away from the guide port 61. The linkage rod 71 is slidably connected to the inner wall of the fixed sleeve 72, and a spring 73 is fixedly installed between the end of the linkage rod 71 and the inner wall of the fixed sleeve 72. The end of the linkage rod 71 away from the fixed sleeve 72 passes through the arch-breaking rod 33 and the transmission gear 63 in sequence. A guide plate 78 corresponding to the linkage rod 71 is fixedly installed on the side of the storage hopper 12.

[0028] During the reciprocating sliding of the anti-arch rod 33, the end of the linkage rod 71 can contact the side of the guide plate 78 as the anti-arch rod 33 moves. When passing the protrusion at the end of the guide plate 78, the linkage rod 71 can be pushed to slide on the inner wall of the fixed sleeve 72. During the process of sliding and resetting the linkage rod 71 in the opposite direction, the linkage rod 71 can slide in the opposite direction under the action of the spring 73, thereby realizing the reciprocating sliding of the linkage rod 71 along the fixed sleeve 72. During this process, since one end of the connecting telescopic rod 77 is fixedly connected to the linkage rod 71 and the other end is hinged to the rotating plate 75, the linkage rod 71 can drive the rotating plate 75 through the connecting telescopic rod 77, so that the rotating plate 75 can reciprocate on the inner wall of the mounting port 74, thereby driving the stirring blade 76 to reciprocate. In conjunction with the reciprocating rotation of the anti-arch rod 33, it is ensured that the material in the storage hopper 12 can be fully stirred, increasing the anti-arching effect while ensuring that the material will not be stuck, so as to quickly unload the material and maintain the normal operation of the intelligent packaging equipment.

[0029] Working principle: During use, the entire spiral unloading hopper is located at the discharge end of the intelligent packaging equipment. It can be used for intelligent packaging and conveying of light biomass materials. Specifically, the material is unloaded into the storage hopper 12 by a loader or grab bucket. The reduction motor 15 is started, which drives the coupling 16 to rotate. The coupling 16 drives the spiral blades 14 to rotate. The rotating spiral blades 14 can push the anti-bridging blades 22 to rotate, turning the material in the storage hopper 12. The upper layer of material in the storage hopper 12 is continuously turned and pushed into the spiral conveyor trough 11 to prevent the material from bridging or arching in the storage hopper 12. At the same time, the rotating spiral blades 14 push the material in the spiral conveyor trough 11 into the discharge port 13 so that the material can be intelligently packaged later. As the arch-breaking blade 22 rotates with the rotating seat 21, it can drive the shaft 23 to rotate synchronously. When the shaft 23 rotates, it can drive the speed regulating roller 52 to rotate through the driven wheel and the synchronous belt. When the speed regulating roller 52 rotates, it can drive the speed regulating ring 56 to rotate, and through the speed regulating ring 56, it can drive the transmission roller 51 to rotate. The drive bevel gear 45 is fixedly connected to the end of the transmission roller 51, so the drive bevel gear 45 can rotate synchronously, and can drive the rotating shaft 42 to rotate through the driven bevel gear 44. When the rotating shaft 42 rotates, it can drive the cam 43 on it to rotate. During the rotation of the cam 43, with the use of the spring 34, the push shaft 31 can slide back and forth, and through the mounting sleeve 32, it can drive the arch-breaking rod 33 to move back and forth inside the storage hopper 12. When the arch-breaking rod 33 slides back and forth, the operator can adjust the reciprocating speed of the arch-breaking rod 33 according to the actual situation of the material in the storage hopper 12, so as to ensure the normal unloading of the material and the normal operation of the intelligent packaging equipment. Specifically, the operator can rotate the adjusting screw 53. The adjusting plate 55 is screwed to the adjusting screw 53 and slidably connected to the guide rod 54. Therefore, when the adjusting screw 53 rotates, it can drive the adjusting plate 55 to slide along the guide rod 54, thereby adjusting the position of the adjusting plate 55 and the speed regulating ring 56. Since the transmission roller 51 and the speed regulating roller 52 are both frustoconical and are arranged opposite each other, the speed regulating ring 56 can change the speed ratio between the transmission roller 51 and the speed regulating roller 52 when the position is adjusted between the transmission roller 51 and the speed regulating roller 52, thereby adjusting the rotation speed of the transmission roller 51, and thus adjusting the reciprocating speed of the arch-breaking rod 33 to cope with different materials. During the reciprocating sliding of the arch-breaking rod 33, its end can reciprocate along the guide opening 61. During this sliding process, the baffle 62 can always block the guide opening 61 to prevent material leakage from the storage hopper 12. Simultaneously, the transmission gear 63 can reciprocate along with the arch-breaking rod 33. The transmission gear 63 meshes with the fixed rack 64. Therefore, during the reciprocating sliding process, under the action of the fixed rack 64, the transmission gear 63 and the arch-breaking rod 33 can reciprocate and rotate to agitate the material in the storage hopper 12, further improving the arch-breaking effect. During the reciprocating sliding of the arch-breaking rod 33, the end of the linkage rod 71 can contact the side of the guide plate 78 as the arch-breaking rod 33 moves. When passing the protrusion at the end of the guide plate 78, the linkage rod 71 can be pushed. During the process of sliding on the inner wall of the fixed sleeve 72 and the linkage rod 71 sliding back in the opposite direction, the linkage rod 71 can slide in the opposite direction under the action of the second spring 73, thereby realizing the reciprocating sliding of the linkage rod 71 along the fixed sleeve 72. During this process, since one end of the connecting telescopic rod 77 is fixedly connected to the linkage rod 71 and the other end is hinged to the rotating plate 75, the linkage rod 71 can drive the rotating plate 75 through the connecting telescopic rod 77, so that the rotating plate 75 can reciprocate on the inner wall of the mounting port 74, thereby driving the stirring blade 76 to reciprocate. With the reciprocating rotation of the arch-breaking rod 33, the material in the storage hopper 12 can be fully stirred, increasing the arch-breaking effect while ensuring that the material will not get stuck, so as to quickly unload the material and maintain the normal operation of the intelligent packaging equipment.

[0030] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
