Description

Technical Field

[0001] This invention belongs to the field of bamboo fiber extrusion production technology, specifically a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation. Background Technology

[0002] The main material used in the production of bamboo fiber pipes is bamboo fiber composite particles. These particles are primarily made from bamboo fiber and PP particles (polypropylene particles). Under high temperature and pressure, bamboo fiber and resin are synthesized to form a high-strength, high-density bamboo-based fiber composite material. This synthesis process is somewhat similar to that of carbon fiber production, both involving the use of high temperature and pressure to tightly bond the fiber and resin, thereby enhancing the overall performance of the material.

[0003] In current technologies, bamboo fiber composite granules are produced with PP granules (polypropylene granules) comprising 20% ​​and bamboo fiber granule powder comprising 80%. During the mixing and extrusion process, the significant polarity difference between bamboo fiber and polypropylene resin can hinder their complete fusion, affecting the interfacial and overall properties of the final composite material. Insufficient mixing can lead to weak interfacial regions in the composite material, which are prone to stress concentration points under stress, thus reducing the strength and toughness of the composite material. Existing mixing equipment attempts to achieve sufficient fusion by increasing the mixing temperature and extending the mixing time, but this increases the overall energy consumption of the equipment, causing unnecessary economic losses and resulting in poor performance.

[0004] Therefore, in response to the above problems, a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation is proposed. Summary of the Invention

[0016] The beneficial effects of this invention are: This invention provides a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation. Through the structural design of the uniform mixing component, the first discharge hopper discharges bamboo fiber particles into a twin-screw hot extruder through an external annular discharge pipe, while the second discharge hopper discharges polypropylene particles into the twin-screw hot extruder through an internal conical discharge pipe. During the simultaneous discharge process, the uniform mixing component evenly disperses the polypropylene particles falling from the internal conical discharge pipe into the bamboo fiber particles, ensuring thorough mixing of the bamboo fiber particles and polypropylene particles entering the twin-screw hot extruder. This facilitates full fusion of the two in subsequent mixing processes, improving the interfacial and overall properties of the final composite material, reducing weak interfacial areas caused by insufficient mixing, thereby improving the strength and toughness of the composite material, reducing the overall power consumption of the device, and enhancing the overall performance of the device.

[0017] This invention provides a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation. Through the structural design of the feeding opening and closing assembly, when the moving feeding pipe is driven upward by the feeding opening and closing assembly, the opening and closing plate is driven to open on the outer annular feeding pipe. Then, when the moving feeding pipe and the outer annular feeding pipe are connected, the opening and closing plate is fully open on the outer annular feeding pipe. Conversely, when the twin-screw hot extruder completes feeding and the moving feeding pipe descends, the opening and closing assembly drives the opening and closing plate to close on the outer annular feeding pipe. This improves the efficiency linkage between the twin-screw hot extruder and the first and second feeding barrels, reduces the number of transmission components and operating keys in the device, and improves the feeding and refining efficiency of the device while reducing the production cost, thus improving the practicality and applicability of the device.

[0018] This invention provides a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation. Through the structural design of pelletizer, third servo motor, agitator column, and agitator fan, when the pelletizer driven by the third servo motor cuts the composite material that has been mixed and extruded on the extrusion seat, the third servo motor simultaneously drives the agitator column to rotate the agitator fan in the cooling box. Through the rotation of the first linkage belt seat, the coolant in the cooling box is driven to circulate efficiently outside the extrusion tube in the extrusion seat. This facilitates the displacement of the coolant in the cooling box, improves the cooling effect on the composite material in the cooling box, reduces the power of frequent coolant circulation in the cooling box, and further reduces the overall power consumption of the device.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Specific implementation examples are given below.

[0036] Example 1 like Figures 1-14As shown, this invention provides a raw material mixing device for bamboo fiber pipe extrusion with high-efficiency heat dissipation, including an accessory box 1. To facilitate the mixing and extrusion of polypropylene granules and bamboo fiber granules, a twin-screw hot extruder 2 is fixedly connected to the top of the accessory box 1. A fixed frame 3 is fixedly connected to one end of the twin-screw hot extruder 2. A fixed feed pipe 4 is fixedly connected to the top of the fixed frame 3. A movable feed pipe 5 is slidably connected to the inner side of the fixed feed pipe 4. To facilitate connecting the movable feed pipe 5 to the twin-screw hot extruder 2 for feeding, an inlet 41 is fixedly connected to the top of the twin-screw hot extruder 2 at a position corresponding to the fixed feed pipe 4. A connecting spring hose 42 is detachably connected to the top of the inlet 41. The fixed feeding pipe 4 is detachably connected to the movable feeding pipe 5. To facilitate the holding of bamboo fiber granules, a first feeding bucket 6 is provided at the top of the fixed feeding pipe 4. To facilitate the holding of polypropylene granules, a second feeding bucket 7 is provided at one end of the first feeding bucket 6. To facilitate the feeding of polypropylene granules in the second feeding bucket 7 into the bamboo fiber granules, a first fixing pipe 8 is fixedly connected to the bottom of the second feeding bucket 7. A second fixing pipe 9 is fixedly connected to the bottom of the first fixing pipe 8. A feeding inclined plate 10 is fixedly connected to the bottom of the inner side of the first fixing pipe 8 at a position corresponding to the second fixing pipe 9. The end of the second fixing pipe 9 away from the first fixing pipe 8 extends into the inner side of the first feeding bucket 6. A third fixing pipe 11 is fixedly connected to the bottom of the second fixing pipe 9 located inside the first feeding bucket 6.

[0037] To facilitate the addition of raw materials to the first discharge bin 6 and the second discharge bin 7, a vertical frame 61 is fixedly connected to one side of the accessory box base 1 near the fixed frame 3. A horizontal frame 62 is fixedly connected to the top of the vertical frame 61. The horizontal frame 62 is fixedly connected to the first discharge bin 6 and the second discharge bin 7. To facilitate workers climbing onto the horizontal frame 62, a ladder 63 is fixedly connected to the side of the vertical frame 61 away from the twin-screw hot extruder 2.

[0038] The feeding opening and closing component is located at the bottom of the first feeding hopper 6. The feeding opening and closing component is used in conjunction with the moving feeding pipe 5 and the first feeding hopper 6. The uniform mixing component evenly disperses the polypropylene particles falling from the moving feeding pipe 5 into the bamboo fiber particles, so that the bamboo fiber particles and polypropylene particles entering the twin-screw hot extruder 2 are fully mixed. This facilitates the full integration of the two in the subsequent mixing process, improves the interfacial and overall properties of the final composite material, reduces the appearance of weak interfacial areas in the composite material due to insufficient mixing, thereby improving the strength and toughness of the composite material, reducing the overall power consumption of the device, and improving the use effect of the device.

[0039] The uniform mixing component is located inside the movable feed pipe 5. It works in conjunction with the first discharge hopper 6 and the second discharge hopper 7. When the movable feed pipe 5 moves upward via the discharge opening and closing component, the second discharge hopper 7 is opened, connecting the movable feed pipe 5 to the second discharge hopper 7. Conversely, when the twin-screw hot extruder 2 finishes feeding and the movable feed pipe 5 descends, the second discharge hopper 7 closes via the discharge opening and closing component. This improves the efficiency linkage between the twin-screw hot extruder 2 and the first and second discharge hoppers 6 and 7, reduces the number of transmission components and operating keys within the device, and improves the efficiency of material feeding and processing while reducing production costs, thus enhancing the practicality and applicability of the device.

[0040] During operation, when it is necessary to mix bamboo fiber granules and polypropylene granules to produce a composite material for bamboo fiber pipes, the workers climb up the horizontal frame 62 via ladder 63, and then pour bamboo fiber granules into the first discharge bucket 6 and polypropylene granules into the second discharge bucket 7.

[0041] Example 2 like Figures 2-8 As shown, in order to facilitate the control of the feeding of the first feeding bucket 6 and the second feeding bucket 7, the feeding opening and closing assembly includes an external annular feeding pipe 12, an internal conical feeding pipe 13, an opening frame 14, an opening and closing seat 15, and an opening and closing plate 16. The bottom end of the first feeding bucket 6 is fixedly connected to the external annular feeding pipe 12, and the bottom end of the third fixed pipe 11 is fixedly connected to the internal conical feeding pipe 13. Both ends of the external annular feeding pipe 12 are fixedly connected to the opening frame 14, and the opening and closing seat 15 is rotatably connected to the inner side of the opening frame 14. In order to facilitate the closing of the external annular feeding pipe 12, the corresponding ends of the two opening and closing seats 15 are fixedly connected to the opening and closing plate 16, and the top end of the opening and closing plate 16 is in contact with the external annular feeding pipe 12 and the internal conical feeding pipe 13.

[0042] To facilitate the opening and closing of the opening and closing plate 16 on the external annular feed tube 12, a first transmission column 18 is rotatably connected to the inner side of the first opening and closing frame 17. The end of the first transmission column 18 near the opening and closing seat 15 passes through the opening frame 14 and is fixedly connected to the opening and closing seat 15. To facilitate the rotation of the first transmission column 18 and the opening and closing seat 15, a first bevel gear 21 is fixedly connected to the end of the first transmission column 18 away from the opening and closing seat 15. A second opening and closing frame 19 is fixedly connected to one side of the external annular feed tube 12. A second transmission column 20 is rotatably connected to the inner side of the second opening and closing frame 19. A second bevel gear 22 is fixedly connected to both ends of the second transmission column 20. The first bevel gear 21 and the second bevel gear 22 are meshed together. To facilitate the rotation of the second transmission column 20, a first lifting belt seat 23 is fixedly connected to the center position of the second transmission column 20.

[0043] The feeding opening and closing assembly also includes a transmission seat 24, a lifting rack 25, a first rotating column 26, a third bevel gear 27, a second lifting belt seat 28, and a lifting opening and closing belt 29. To facilitate the opening and closing of the opening and closing plate 16 on the external annular feeding pipe 12 when moving on the movable feeding pipe 5, a transmission seat 24 is fixedly connected to the top of the fixed feeding pipe 4 at a position corresponding to the second opening and closing frame 19. To facilitate the movement of the movable feeding pipe 5 within the fixed feeding pipe 4, the outer side of the movable feeding pipe 5 and the transmission seat 24 are also connected. A lifting rack 25 is fixedly connected to the corresponding position. A first rotating column 26 is rotatably connected to one end inside the transmission seat 24. A third bevel gear 27 is fixedly connected to the end of the first rotating column 26 near the lifting rack 25. In order to facilitate the rotation of the first lifting belt seat 23 and the second transmission column 20 through the first rotating column 26, a second lifting belt seat 28 is fixedly connected to the end of the first rotating column 26 away from the lifting rack 25. A lifting opening and closing belt 29 is provided between the second lifting belt seat 28 and the first lifting belt seat 23.

[0044] To facilitate the rotation of the first rotating column 26, the feeding opening and closing assembly also includes a first servo motor 30, a second rotating column 31, a fourth bevel gear 32, and a transmission gear 33. The first servo motor 30 is fixedly connected to the inner side of the transmission base 24 at a position corresponding to the first rotating column 26. The output end of the first servo motor 30 is fixedly connected to the first rotating column 26. The second rotating column 31 is rotatably connected to the inside of the transmission base 24 at a position corresponding to the lifting rack 25. The transmission gear 33 is fixedly connected to the end of the second rotating column 31 located inside the transmission base 24. To facilitate the rotation of the second rotating column 31, the transmission gear 33 is meshed with the third bevel gear 27. The fourth bevel gear 32 is fixedly connected to the end of the second rotating column 31 located outside the transmission base 24. To facilitate the movement of the lifting rack 25 and the moving feeding tube 5 within the fixed feeding tube 4, the fourth bevel gear 32 is meshed with the lifting rack 25.

[0045] During operation, when raw materials need to be added to the twin-screw hot extruder 2, the operator starts the first servo motor 30. The output of the first servo motor 30 drives the first rotating column 26 to rotate. The first rotating column 26 then drives the third bevel gear 27 and the second lifting belt seat 28 to rotate. The third bevel gear 27 drives the transmission gear 33 and the second rotating column 31 to rotate. The fourth bevel gear 32 then drives the lifting rack 25 and the fixed feed tube 4 to move towards the external annular feed tube 12. At the same time, the rotating second lifting belt seat 28 drives the first lifting belt seat 23 and the second transmission column 20 to rotate via the lifting opening and closing belt 29. The second transmission column 20 then drives the first bevel gear 21 and the first transmission column via the second bevel gear 22. The first drive column 18 rotates, and the two opening and closing plates 16 on the outer annular feed tube 12 of the opening and closing seat 15 open relative to each other with the opening and closing seat 15 as the center. As the moving feed tube 5 moves towards the outer annular feed tube 12, the opening and closing plates 16 open on the outer annular feed tube 12. When the moving feed tube 5 moves to the position connected with the outer annular feed tube 12, the opening and closing plates 16 are fully opened on the outer annular feed tube 12. The opening and closing plate 16 is driven to close on the outer annular feed tube 12 by the feed opening and closing assembly, which improves the efficiency linkage between the twin-screw hot extruder 2 and the first discharge hopper 6 and the second discharge hopper 7, reduces the number of transmission parts and operation keys in the device, and improves the efficiency of feeding and refining the device while reducing the production cost of the device, thus improving the practicality of the device.

[0046] Example 3 like Figure 8 and Figure 9 As shown, in order to fully and uniformly mix polypropylene granules and bamboo fiber granules during feeding, the uniform mixing component includes a dispersing frame 34, a conical dispersing column 35, a dispersing wheel 36, a ring rack 37, a second servo motor 38, a first dispersing gear 39, and a second dispersing gear 40. The dispersing frame 34 is fixedly connected to the bottom of the inner side of the moving feed pipe 5. In order to disperse the falling polypropylene granules, the top of the dispersing frame 34 is fixedly connected to the conical dispersing column 35. To facilitate the continuous and uniform dispersion of the falling polypropylene granules onto the falling bamboo fiber granules... In the pellet, a flying wheel 36 is rotatably connected to the bottom ring side of the conical dispersing column 35. A ring rack 37 is fixedly connected to the inner side of the flying wheel 36. In order to facilitate the rotation of the flying wheel 36, a second servo motor 38 is fixedly connected to the inner side of the conical dispersing column 35. A first stirring gear 39 is fixedly connected to the output end of the second servo motor 38. A second stirring gear 40 is rotatably connected between the ring rack 37 and the first stirring gear 39 and the conical dispersing column 35. The second stirring gear 40 is meshed with both the ring rack 37 and the first stirring gear 39.

[0047] During operation, the operator starts the first servo motor 30 and the second servo motor 38 simultaneously. The output of the second servo motor 38 drives the first agitation gear 39 to rotate. The first agitation gear 39, through the second agitation gear 40 and the ring rack 37, drives the flywheel 36 to rotate at high speed on the conical dispersing column 35. The high-speed rotation of the flywheel 36 causes the polypropylene particles falling on it to fly outward, thus scattering the polypropylene particles into the bamboo fiber particles falling into the moving feed pipe 5. This allows the bamboo fiber particles and polypropylene particles entering the twin-screw hot extruder 2 to be uniformly mixed, facilitating their full integration in subsequent mixing processes. This improves the interfacial and overall properties of the final composite material, reduces weak interfacial areas in the composite material caused by insufficient mixing, thereby improving the strength and toughness of the composite material and reducing the overall power consumption of the device.

[0048] Example 4 like Figures 11-14 As shown, to facilitate the extrusion of the composite material mixed by the twin-screw hot extruder 2 into granules, an extrusion seat 43 is provided at the end of the twin-screw hot extruder 2 away from the fixed frame 3. To facilitate the cooling of the extrusion tube inside the extrusion seat 43, a cooling box 44 is provided on the circumferential side of the extrusion seat 43. The cooling box 44 is fixedly connected to the twin-screw hot extruder 2. A pelletizer 45 is fixedly connected at the end of the accessory box seat 1 away from the fixed frame 3. A pelletizer column 46 is rotatably connected at the center position of the pelletizer 45 near the end of the twin-screw hot extruder 2. To facilitate the cutting of the composite material extruded by the extrusion seat 43 into granules, multiple pelletizer blades 47 are detachably connected to the end of the pelletizer column 46 near the end of the twin-screw hot extruder 2. The pelletizer blades 47 are in contact with the extrusion seat 43. To facilitate the rotation of the pelletizer column 46, a third servo motor 48 is fixedly connected to the end of the pelletizer 45 away from the twin-screw hot extruder 2. The output end of the third servo motor 48 is fixedly connected to the pelletizer column 46.

[0049] To improve the cooling effect on the extruder 43, a stirring column 49 is provided at the top of the extruder 43. Both ends of the stirring column 49 are rotatably connected to fixing strips. The fixing strip closer to the accessory box 1 is fixedly connected to the cooling box 44, and the fixing strip further away from the accessory box 1 is fixedly connected to the pelletizer 45. Multiple fifth bevel gears 50 are fixedly connected to the circumferential side of the stirring column 49 inside the cooling box 44. An agitator column 51 is rotatably connected inside the cooling box 44 at a position corresponding to the fifth bevel gears 50. A sixth bevel gear 52 is fixedly connected to the top of the agitator column 51, thus facilitating the driving of the agitator fan 5 through the stirring column 49. 3. The device rotates inside the cooling box 44. The sixth bevel gear 52 meshes with the fifth bevel gear 50. To facilitate the rotation of the stirring column 49, a stirring fan 53 is fixedly connected to the bottom of the stirring column 51. The end of the pelletizing column 46 away from the twin-screw hot extruder 2 is fixedly connected to the first linkage belt seat 54. The end of the stirring column 49 away from the twin-screw hot extruder 2 is fixedly connected to the second linkage belt seat 55. A linkage stirring belt 56 is provided between the first linkage belt seat 54 and the second linkage belt seat 55. To facilitate the composite material after pelletizing, a collection box 57 is provided at the bottom of the pelletizing frame 45.

[0050] During operation, when it is necessary to pelletize the composite material extruded in the extrusion seat 43, the third servo motor 48 is started, and the output end of the third servo motor 48 drives the pelletizing column 46 and the pelletizing blade 47 to rotate. The pelletizing blade 47 then pelletizes the cooled composite material extruded through the extrusion tube in the extrusion seat 43. While the third servo motor 48 drives the pelletizing blade 47 to shear the composite material that has been compounded and extruded on the extrusion seat 43, the third servo motor 48 drives the stirring column 49 to rotate through the linkage stirring belt 56 on the pelletizing column 46. The stirring column 49 drives the stirring fan 53 to rotate in the cooling box 44. Through the rotation of the first linkage belt seat 54, it drives the coolant in the cooling box 44 to circulate efficiently outside the extrusion tube in the extrusion seat 43. This facilitates the displacement of the coolant in the cooling box 44, improves the cooling effect of the composite material in the cooling box 44, reduces the power of frequent circulation of coolant in the cooling box 44, and further reduces the overall power consumption of the device.

[0051] Example 5 like Figure 2 and Figure 14 As shown, in order to facilitate the circulation of the coolant used for cooling in the cooling tank 44, a cold circulation tank 58 is provided on one side of the accessory box base 1 near the end of the collection box 57. A circulating water pump 59 is fixedly connected to the top of the cold circulation tank 58. The first circulation port of the circulating water pump 59 is fixedly connected to the cold circulation tank 58, and a circulating water pipe 60 is fixedly connected to the second circulation port of the circulating water pump 59. The end of the circulating water pipe 60 away from the cold circulation tank 58 is plugged into the cooling tank 44.

[0052] During operation, when the temperature sensor built into the cooling box 44 detects that the coolant temperature in the cooling box 44 is high, it starts the cold circulation box 58 and the circulating water pump 59 through the signal module. Then, the circulating water pump 59 replaces the coolant with a higher temperature in the cooling box 44 and the coolant with a lower temperature in the cold circulation box 58 through the circulating water pipe 60, thereby improving the cooling effect of the cooling box 44 on the composite material in the extrusion seat 43.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
