Detailed Implementation

[0025] 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.

[0026] Example 1, please refer to Figures 1-5 and Figures 11-13 The present invention provides a technical solution: a method for melt blending and molding bio-based materials with nanofiller dispersion reinforcement, comprising the following steps: S1. The nanofiller and bio-based material are added into the sleeve 100 through the hopper 101. The motor 103 is started to drive the rotating rod 200 to rotate, so that the conveying blade 201 sends the material into the extrusion chamber 109 and heats it through the heating chamber 106 during the conveying process. S2. The material is squeezed and stirred to a molten state by the cooperation of the stirring blade 202 and the stirring block 110. Then the cooling chamber 104 cools the material to prevent the material from overheating and sends the material into the diversion mechanism 300. S3. The molten material is divided and stirred again by the diversion mechanism 300 to make the material more uniformly mixed; S4. The uniformly mixed material enters the conveying chamber 111, is conveyed by the guide vane 205, and the material temperature is kept constant by the constant temperature chamber 105, and finally extruded into shape.

[0027] The diversion mechanism 300 includes a fixed sleeve 301, the outer wall of which is fixedly connected to the inner wall of the sleeve 100. A diversion hole 302 is provided on the inner wall of the fixed sleeve 301, communicating with the interior of the fixed sleeve 301. The diversion hole 302 is used to divert material. A diversion plate 303 is fixedly connected to the outer wall of the fixed sleeve 301, positioned at the gap in the diversion hole 302, and used to guide the material flow. A rotating sleeve 304 is fixedly connected to the outer wall of the rotating rod 200, located inside the fixed sleeve 301. The outer wall of the rotating sleeve 304 is fixedly connected to... There is a second stirring blade 305, which is used to guide the diverted material. A hammer-shaped head 306 is fixedly connected to the outer wall of the second stirring blade 305. The hammer-shaped head 306 contacts the inner wall of the second fixed sleeve 301 and is used to stir the molten material. The bottom of the hopper 101 is fixedly connected to the top of the first fixed sleeve 107. The inner wall of the first fixed sleeve 107 is fixedly connected to the outer wall of the sleeve 100. The hopper 101 communicates with the inside of the sleeve 100. The outer wall of the first fixed sleeve 107 is fixedly connected to the outer wall of the motor 103 through a retainer. The output end of the motor 103 is driven by the outer wall of the rotating rod 200 through a belt. The inner wall of stirring blade 202 is fixedly connected to the outer wall of rotating rod 200. The outer wall of stirring block 110 is fixedly connected to the wall of extrusion chamber 109. The inner wall of conveying blade 201 is fixedly connected to the outer wall of rotating rod 200. Stirring block 110 is disposed in the gap between stirring blade 202 for stirring and extruding materials. Buffer blade 203 is fixedly connected to the outer wall of rotating rod 200. Buffer blade 203 is disposed in the gap between stirring blade 202 and fixed sleeve 301. The end of buffer blade 203 near fixed sleeve 301 contacts the outer wall of fixed sleeve 301. Buffer blade 203 is used to buffer the molten material. The heating chamber 106 is fixedly connected to the outer wall of the fixed sleeve 107. The position of the heating chamber 106 matches the position of the conveying blade 201. The heating chamber 106 is used to heat the material conveyed by the conveying blade 201. The outer wall of the sleeve 100 is provided with a guide hole 108. The inner wall of the cooling chamber 104 is fixedly connected to the outer wall of the sleeve 100. The position of the cooling chamber 104 matches the position of the guide hole 108. Both the cooling chamber 104 and the guide hole 108 are used to guide the flow of coolant. The inner wall of the constant temperature chamber 105 is fixedly connected to the outer wall of the sleeve 100. The position of the constant temperature chamber 105 matches the position of the guide blade 205. When bio-based materials reinforced with nanofillers are melt-blended and extruded, the nanofiller melt is prone to agglomeration, affecting the uniformity of the blend. Furthermore, bio-based polymer materials have poor thermal stability and are prone to thermal degradation when heated during blending with nanofillers, reducing the strength of the nanofillers. Therefore, a flow divider 300 is set up to extrude and divide the material to prevent the nanofillers from agglomerating during the extrusion and stirring process, which would prevent them from mixing with the biomaterials and increase the uniformity of the material blend. At the same time, the flow divider 300 breaks up the agglomerated nanomaterials and further stirs them, so that the nanomaterials are fully mixed with the biomaterials, increasing the uniformity of the blended material. Meanwhile, during the material stirring and heating process, the buffer blade 203 guides the material flow, so that the material is buffered after stirring and heating, and works with the cooling chamber 104 to reduce the material temperature, preventing the material from being excessively heated due to continuous stirring in the molten state, which would cause the biomaterials to degrade due to high temperature, and increasing the stability of the material blend in the molten state. When material is fed into the sleeve 100 through the hopper 101, the start motor 103 drives the rotating rod 200 to rotate, causing the material inside the sleeve 100 to be conveyed to the extrusion chamber 109 through the conveying blade 201. During the conveying process, the material is heated by the heating chamber 106. After the material enters the extrusion chamber 109, it is intercepted by the stirring block 110, and the stirring blade 202 rotates within the gap of the stirring block 110 to extrude and stir the material, mixing the nanofiller with the bio-based material. The material is further heated by the extrusion, bringing it into a molten state. After the material has passed through the extrusion and stirring process, the material in the molten state is conveyed at a constant speed by the buffer blade 203. During the conveying process, coolant is injected into the cooling chamber 104, and the coolant enters the guide hole 108 to cool the molten material that has passed through the buffer blade 203, preventing the material from continuing to heat up after being extruded and stirred by the stirring block 110 and the stirring blade 202, which could lead to the degradation of the bio-based material. After being conveyed by the impeller 203 and cooled by the coolant, the material is squeezed by the buffer impeller 203 and guided by the diverter plate 303. It is then diverted through the diverter hole 302 and squeezed into the fixed sleeve 301. The rotating sleeve 304 drives the stirring impeller 305 and the hammer head 306 to rotate inside the fixed sleeve 301, breaking up and stirring the agglomerated nanomaterials diverted into the fixed sleeve 301 through the diverter hole 302. This prevents the nanofiller from agglomerating, which would reduce the blendability and allow the nanofiller and bio-based material to mix further. During the mixing process, the material is further heated and enters the conveying chamber 111. The guide impeller 205 conveys the mixed material, and the constant temperature chamber 105 keeps it at a constant temperature during the conveying process. This allows the material, after being stirred and mixed by the diverter 300, to be cooled after entering the conveying chamber 111 and conveyed through the guide impeller 205. Finally, the material is extruded and shaped at the extrusion outlet of the sleeve 100 by the conveying impeller 204.

[0028] Example 2, based on Example 1, please refer to... Figures 6-10The present invention provides a technical solution as follows: A sliding plate 207 is slidably connected to the outer wall of a rotating rod 200. The sliding plate 207 is disposed at the gap of the guide vane 205. An adjusting vane 208 is fixedly connected to the outer wall of the sliding plate 207. The adjusting vane 208 is used to guide the molten material. The sliding plate 207 is used to drive the adjusting vane 208 to adjust the guiding gap. A guide groove 206 is formed on the outer wall of the rotating rod 200. The guide groove 206 penetrates the outer wall of the rotating rod 200 and communicates with the interior of the rotating rod 200. A connecting rod 210 is slidably connected to the wall of the guide groove 206. The end of the connecting rod 210 near the sliding plate 207 is fixedly connected to the inner wall of the sliding plate 207. The guide groove 206 is used to limit the movement of the connecting rod 210. A sliding rod 209 is dynamically connected. The outer wall of the sliding rod 209 is fixedly connected to the end of the connecting rod 210 near the sliding rod 209. A hydraulic cylinder 102 is fixedly connected to the end of the rotating rod 200 away from the guide vane 205. The output end of the hydraulic cylinder 102 is rotatably connected to the end of the sliding rod 209 near the hydraulic cylinder 102 through a bearing. The hydraulic cylinder 102 is used to drive the sliding rod 209 to slide on the inner wall of the rotating rod 200. A second conveying vane 204 is fixedly connected to the outer wall of the rotating rod 200. The second conveying vane 204 is located on the side of the rotating rod 200 away from the guide vane 205. The second conveying vane 204 is used to guide the material. The width of the sliding plate 207 is greater than the length of the guide groove 206. The sliding plate 207 is used to isolate the material outside the guide groove 206. When bio-based materials reinforced with nanofillers are melt-blended and extruded, the nanofiller melt is prone to agglomeration, affecting the uniformity of the blend. Furthermore, the bio-based polymer material has poor thermal stability, and the nanofiller is prone to thermal degradation during the blending process, reducing the strength of the nanofiller. In addition, during the conveying process at the melting critical point, local cooling can cause the material to agglomerate prematurely, affecting the uniformity of the material forming. Therefore, the regulating blade 208 is set to change the conveying gap of the guide blade 205 to the material, so that the material maintains its own fluidity and temperature uniformity during the conveying process, and prevents the material from agglomerating and adhering due to local temperature drop during the conveying process at the melting critical point, which would affect the conveying and extrusion forming of the material. After being mixed by the diversion mechanism 300, the material enters the conveying chamber 111. The rotating rod 200 drives the guide vanes 205 to rotate within the conveying chamber 111, thus conveying the material. During conveying, the hydraulic cylinder 102 drives the sliding rod 209 to slide back and forth on the inner wall of the rotating rod 200. This causes the sliding rod 209 to drive the connecting rod 210 to slide within the guide groove 206. The connecting rod 210, guided by the guide groove 206, drives the sliding plate 207 to slide on the outer wall of the rotating rod 200. Simultaneously, the sliding plate 207 drives the adjusting vanes 208 to move between the guide vanes 205. The material conveyed by the guide vane 205 is squeezed in the gap, while the material pressure in the gap between the other side of the regulating vane 208 and the guide vane 205 is reduced, so that the material with high pressure flows to the side with low pressure. This prevents the material from agglomerating and adhering due to a local temperature drop during the conveying process at the melting critical point, which would affect the conveying of the material. As the sliding plate 207 slides on the outer wall of the guide vane 205 driven by the connecting rod 210, it blocks the material and prevents the material from entering the guide groove 206, thus limiting the sliding range of the connecting rod 210 in the guide groove 206.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
