Description

Technical Field

[0001] This invention relates to the field of 3D filament fabrication technology, specifically to a method and related equipment for preparing lavender-based biodegradable 3D filaments. Background Technology

[0002] Lavender raw materials may contain essential oils and fragrance components, which may evaporate or trigger chemical reactions at high temperatures, affecting the melt extrusion process. Volatile components in lavender may cause bubble formation, affecting print quality.

[0003] Essential oils or extracts with aroma and potential antibacterial properties are extracted from lavender plants. When these substances are mixed with other raw materials, these components may evaporate or trigger chemical reactions at high temperatures when the mixture enters a molten state, or even generate gases that affect the melt extrusion process. These gases can enter the interior of the melt extruder and participate in the melt extrusion process. Otherwise, air bubbles will be present in the melt-extruded biodegradable 3D filaments. The presence of air bubbles will cause problems with the quality of the 3D filaments and may even cause them to break during the forming process. To address this, a method for preparing biodegradable 3D filaments made from lavender and related equipment have been invented. Summary of the Invention

The telescopic end of the first telescopic component is fixedly connected to a first disc, and a folding assembly is installed on one side of the first disc. The folding assembly includes a first turntable and a second turntable. One side of the first turntable and one side of the first disc are rotatably connected. The inner wall of the first turntable is slidably connected to the outer wall of the main rod. The second turntable is fixedly installed on the main rod. Several first fixing parts are installed between the first turntable and the second turntable. Adjacent first fixing parts are slidably connected. The first fixing component is rotatably connected to the outside of the first stirring blade, and the first fixing component is rotatably connected to the inside of the first rotating component. The inner wall of the first rotating component is fixed to the first stirring blade. A torsion spring is installed at the rotatable connection between the first rotating component and the first fixing component. Through holes are opened on both sides of the first fixing component.

[0006] Furthermore, the mixing device includes a mixing tank, which is fixedly mounted on a frame. A second motor is fixedly connected to the mixing tank. An output shaft is fixedly connected to the output end of the second motor. A transmission rod is slidably connected to the outer wall of the output shaft. A stirring blade is fixedly connected to the outer wall of the transmission rod. A roller is rotatably connected to the outer wall of the transmission rod. A contour piece is fixedly connected to the top of the mixing tank. The outer wall of the roller and the top of the contour piece are adapted to each other.

[0007] Furthermore, the separating device includes a first partition plate, which is fixedly installed inside the frame. The inner wall of the first partition plate is rotatably connected to the outer wall of the main member. A second telescopic member is fixedly connected to one side of the first partition plate.

A connecting component is installed between the first and second partition plates. A folding component is installed on one side of the second partition plate.

[0008] Furthermore, the connecting component includes a first connecting pipe, and a first partition and a second partition are respectively fixedly connected to a first connecting pipe. A telescopic pipe is slidably connected inside the first connecting pipe, and an electrically controlled valve is fixedly connected inside the first connecting pipe.

[0009] Furthermore, the connecting component includes a second connecting pipe, with the second connecting pipe fixedly connected to the first partition and the second partition respectively, and a third motor fixedly connected to the second connecting pipe, with a valve plate fixedly connected to the output end of the third motor.

[0010] A method for preparing lavender-based biodegradable 3D filaments, using the aforementioned equipment for preparing lavender-based biodegradable 3D filaments, the method comprising: Lavender raw material processing: obtaining lavender raw materials, drying and grinding the lavender raw materials to obtain lavender raw materials; Raw material mixing: Lavender raw materials and biodegradable substrates are put into a mixing device and mixed in the mixing device to obtain mixed raw materials; Melt extrusion: The mixed raw materials in the mixing equipment are moved to the internal chamber of the frame, and after melting, vacuuming and extrusion, wire is obtained; Cooling and collecting: Cooling and shaping the wire and winding it up.

[0011] The internal chambers of the frame include a stirring and melting chamber, a vacuum chamber, and an extrusion chamber. The stirring and melting chamber and the vacuum chamber each contain a folding assembly for stirring the mixed raw materials. The stirring and melting chamber heats the mixed raw materials to obtain a molten mixture. The folding assembly stirs the mixed raw materials. The vacuum chamber is equipped with a vacuum pump to keep the interior of the vacuum chamber in a vacuum state.

[0012] The internal chambers of the frame are divided into a stirring and melting chamber, a vacuum chamber, and an extrusion chamber by a partition device. By changing the volume inside the stirring and melting chamber, pressure is applied to the molten mixture, causing it to move from the stirring and melting chamber to the vacuum chamber. Similarly, by changing the volume inside the vacuum chamber, pressure is applied to the molten mixture, causing it to move from the vacuum chamber to the extrusion chamber. The volume of the molten mixture inside the vacuum chamber is smaller than the volume inside the vacuum chamber.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The method and equipment for preparing biodegradable 3D filaments made from lavender utilize a folding stirring device and a separating device. The separating device divides the interior of the frame into at least three chambers. Folding components are installed inside the stirring and melting chamber and the vacuum chamber. The folding components stir the mixture to facilitate rapid melting. Simultaneously, the mixture is stirred in the vacuum chamber. Volatile components in the molten mixture generate gas, which is quickly extracted by a vacuum pump. This rapid removal of gas from the molten mixture ensures the quality of the filaments after forming.

[0014] Meanwhile, the distance between turntables one and two is variable due to the folding assembly, and the folding assembly can rotate with the main rod. Since it is necessary to move the molten mixture between the chambers, the distance between turntables one and two is changed to further reduce the minimum volume inside the chamber. By changing the volume inside the stirring and melting chamber, pressure is applied to the molten mixture, causing it to move from the stirring and melting chamber to the vacuum chamber. By changing the volume inside the vacuum chamber, pressure is applied to the molten mixture, causing it to move from the vacuum chamber to the extrusion chamber. The folding assembly can change between unfolded and folded states to change the volume inside the chamber, ensuring the practicality of the preparation equipment.

[0015] With the connection pipe and telescopic pipe, the distance between the first and second partitions is variable. The telescopic pipe connects the space on one side of the first partition and the space on the other side of the second partition, thus allowing the molten mixture to pass through the separation device. This separation device is used between the vacuum chamber and the extrusion chamber, so that when the molten mixture is moved into the extrusion chamber, the second partition moves, and the telescopic pipe can still transport the molten mixture during the movement of the second partition, ensuring the stability of the pressure inside the extrusion chamber.

[0019] like Figure 1 - Figure 10 As shown, the present invention provides a technical solution: a preparation device for biodegradable 3D filaments made of lavender, including a frame 1, a main rod 2 rotatably connected to the inner wall of the frame 1, a No. 1 motor 3 for controlling the rotation of the main rod 2 fixedly connected to one end of the frame 1, a folding stirring device 4 installed inside the frame 1, a vacuum pump 7 installed inside the frame 1, and a spiral conveying blade 5 fixedly connected to the outer wall of the main rod 2.

The folding assembly includes a first turntable 403 and a second turntable 405. One side of the first turntable 403 is rotatably connected to one side of the first disc 402. The inner wall of the first turntable 403 is slidably connected to the outer wall of the main rod 2. The second turntable 405 is fixedly installed on the main rod 2. Several first fixing parts 404 are installed between the first turntable 403 and the second turntable 405. Adjacent first fixing parts 404 are slidably connected to each other. A first fixing component 404 is externally rotatably connected to a first stirring blade 406, and an internal rotating component 408 is internally rotatably connected to the first fixing component 404. The inner wall of the first rotating component 408 is fixed to the first stirring blade 406. A torsion spring 407 is installed at the rotatable connection between the first rotating component 408 and the first fixing component 404. Through holes 409 are provided on both sides of the first fixing component 404.

[0020] The mixing device 6 includes a mixing tank 601, which is fixedly mounted on the frame 1. A second motor 602 is fixedly connected to the mixing tank 601. An output shaft is fixedly connected to the output end of the second motor 602. A transmission rod 603 is slidably connected to the outer wall of the output shaft. A stirring blade is fixedly connected to the outer wall of the transmission rod 603. A roller 604 is rotatably connected to the outer wall of the transmission rod 603. A contour piece 605 is fixedly connected to the top of the mixing tank 601. The outer wall of the roller 604 and the top of the contour piece 605 are compatible.

[0021] The separating device 8 includes a first partition 801, which is fixedly installed inside the frame 1. The inner wall of the first partition 801 is rotatably connected to the outer wall of the main rod 2. A second telescopic member 802 is fixedly connected to one side of the first partition 801. A second partition 803 is fixedly connected to the telescopic end of the second telescopic member 802. Material passage holes are respectively opened on the first partition 801 and the second partition 803. A connecting component is installed between the first partition 801 and the second partition 803. A folding component is installed on one side of the second partition 803.

[0022] The connecting assembly includes a first connecting pipe 804, a first partition 801 and a second partition 803 respectively fixedly connected to the first connecting pipe 804, a telescopic pipe 805 slidably connected inside the first connecting pipe 804, and an electrically controlled valve fixedly connected inside the first connecting pipe 804.

[0023] The connecting component includes a second connecting pipe 806, a first partition 801 and a second partition 803 respectively fixedly connected to the second connecting pipe 806, a third motor 807 fixedly connected to the second connecting pipe 806, and a valve plate 808 fixedly connected to the output end of the third motor 807.

[0024] A method for preparing lavender-based biodegradable 3D filaments, using the aforementioned equipment for preparing lavender-based biodegradable 3D filaments, includes the following steps: Lavender raw material processing: obtaining lavender raw materials, drying and grinding the lavender raw materials to obtain lavender raw materials; Raw material mixing: Lavender raw materials and biodegradable substrates are fed into mixing device 6 and mixed in the mixing device to obtain mixed raw materials; Melt extrusion: The mixed raw materials in the mixing equipment are moved to the internal chamber of frame 1, and after melting, vacuuming and extrusion, wire is obtained; Cooling and collecting: Cooling and shaping the wire and winding it up.

[0025] The internal chambers of frame 1 include a stirring and melting chamber, a vacuum chamber, and an extrusion chamber. The stirring and melting chamber and the vacuum chamber each contain a folding assembly for stirring the mixed raw materials. The stirring and melting chamber heats the mixed raw materials to obtain a molten mixture. The folding assembly stirs the mixed raw materials. The vacuum chamber is equipped with a vacuum pump 7 to maintain a vacuum inside the vacuum chamber.

[0026] The internal chamber of frame 1 is divided into a stirring and melting chamber, a vacuum chamber, and an extrusion chamber by a partition device 8. By changing the volume inside the stirring and melting chamber, pressure is applied to the molten mixture, causing it to move from the stirring and melting chamber to the vacuum chamber. By changing the volume inside the vacuum chamber, pressure is applied to the molten mixture, causing it to move from the vacuum chamber to the extrusion chamber. The volume of the molten mixture inside the vacuum chamber is smaller than the volume inside the vacuum chamber.

[0027] The lavender raw material is dried and ground to remove moisture. The lavender powder is then used as the lavender raw material. This lavender raw material is mixed with other biodegradable substrates, including but not limited to polylactic acid and polyhydroxyalkanoates (PHA) or mixtures thereof. These materials are biodegradable in the natural environment. After processing, the lavender is dehydrated to prevent the formation of gas within the frame 1 due to high temperatures, as the presence of gas would affect the quality of the 3D filaments. The lavender raw material and other biodegradable substrates are then transferred to a mixing container. In the mixing device 6, the raw materials are mixed to obtain a mixed raw material. After mixing, the discharge end of the mixing tank 601 is opened, and the mixed material is transferred to the stirring and melting chamber. The stirring and melting chamber heats and stirs the mixed raw material to obtain a molten mixture. The molten mixture is transferred to the vacuum chamber. The vacuum pump 7 can suck out the gas inside the vacuum chamber and make the vacuum chamber a negative pressure state. Then the molten mixture is transferred from the vacuum chamber to the extrusion chamber. The extrusion chamber is used to extrude the wire. After that, the wire is cooled and collected to complete the preparation of the biodegradable 3D wire.

[0028] The output end of motor 602 rotates, the transmission rod 603 rotates, and the roller 604 contacts the top contour of the contour part 605 under the action of gravity. During the rotation of the transmission rod 603, the roller 604 rotates, and the top contour causes the transmission rod 603 to move up and down during the rotation, thereby ensuring the uniformity of mixing.

[0029] The folded stirring device 4 in the stirring and melting chamber is in the unfolded state, which can realize the stirring of the mixture. The first motor 3 controls the main rod 2 to rotate. The rotation of the main rod 2 causes the folded stirring device 4 to rotate, and the first fixed part 404 moves. The first rotating part 408 inside is affected by other first fixed parts 404. When the first rotating part 408 and the first fixed part 404 come into contact, the first fixed part 404 continues to move. When the contact position between the first fixed part 404 and another adjacent first fixed part 404 moves to the through hole 409, the torsion spring 407 causes the first rotating part 408 to have a rotation tendency. One end of the first rotating part 408 will rotate to the other end under the rotation tendency. Inside the first fixed component 404, the change in the rotation angle of the first rotating component 408 causes the rotation angle of the first stirring blade 406 to change synchronously. The rotation of the main rod 2 causes the folding stirring device 4 to rotate. Through the setting of the folding assembly, the distance between the first turntable 403 and the second turntable 405 is variable. At the same time, the folding assembly can rotate with the rotation of the main rod 2. Since it is necessary to move the molten mixture between the chambers, by changing the distance between the first turntable 403 and the second turntable 405, the minimum volume inside the chamber is further reduced, so that the folding assembly can achieve two states of unfolding and folding, so as to change the volume inside the chamber and ensure the practicality of the preparation equipment.

[0030] The telescopic end of the first telescopic component 401 moves, causing the first disc 402 to move. The folding stirring device 4 changes from an unfolded state to a folded state. The first turntable 403 and the second turntable 405 rotate with the rotation of the main rod 2. The first disc 402 and the first turntable 403 move synchronously, while the position of the second turntable 405 on the main rod 2 is fixed. By changing the distance between the first turntable 403 and the second turntable 405, the two states of the folding stirring device 4 can be changed.

[0031] like Figure 9As shown, the positions of the first rotating component 408 and the first stirring blade 406 are fixed. The first rotating component 408 always has a tendency to rotate under the action of the torsion spring 407. The first rotating component 408 passes through the through hole 409 of the first fixed component 404, but is restricted by the adjacent first fixed component 404, so that the first rotating component 408 and the first stirring blade 406 remain in the current position. When the adjacent first fixed components 404 move, the folding assembly is unfolded. When the positions of the through holes 409 on the two adjacent first fixed components 404 coincide, one end of the first rotating component 408 passes through... The overlapping position of the two through holes 409 will come into contact with the first rotating part 408 in another first fixing part 404. Due to the design of the through holes 409, when the two through holes 409 begin to overlap, the first rotating part 408 is not restricted by the adjacent first fixing part 404. The first rotating part 408 moves under the action of the torsion spring 407. When folding, the adjacent first fixing parts 404 move in opposite directions. Due to the inclined surface on the first rotating part 408, the adjacent first rotating part 408 contacts the inclined surface and applies a force to it, thereby causing the first rotating part 408 to move in opposite directions to complete the storage.

[0032] like Figure 6 As shown, the second connecting pipe 806 on partition 1 801 and the second connecting pipe 806 on partition 2 803 can be fitted together. This design allows the mixed molten material to move through the interior of the connecting pipe on partition 1 801 to the inner wall of the connecting pipe on partition 2 803 during the movement between chambers. This allows the mixed molten material to move from a spatial position on the side of partition 1 801 to a spatial position on the side of partition 2 803. There is a valve in the second connecting pipe 806. Motor 3 807 controls the valve plate 808 to rotate, and the valve plate 808 closes the connecting pipe. Valves are respectively installed on the connecting pipes of partition 1 801 and partition 2 803. When the valve closes the connecting pipe, the telescopic end of the second telescopic member 802 moves, controlling the movement of partition 2 803, which compresses the chamber to move the molten material inside the chamber to the next chamber. Motor 3 807 then controls the valve plate 808 to rotate, thus closing the connecting pipe.

[0033] like Figure 5As shown, the telescopic tube 805 is slidably connected to the first connecting tube 804. The telescopic tube 805 allows for variable-distance transport between the first partition 801 and the second partition 803. The separator 8 using this structure is mainly used in the extrusion chamber and the vacuum chamber. When the molten mixture in the vacuum chamber is moved to the extrusion chamber, the electrically controlled valve opens the first connecting tube 804, and the telescopic end of the second telescopic member 802 inside the separator 8 between the extrusion chamber and the vacuum chamber contracts, increasing the internal volume of the extrusion chamber. This increases the speed at which the internal volume of the extrusion chamber increases and the molten mixture flows into the extrusion chamber. With the same feeding speed, the distance between the first partition 801 and the second partition 803 is variable through the setting of the first connecting pipe 804 and the telescopic pipe 805. The telescopic pipe 805 enables communication between the space on one side of the first partition 801 and the space on one side of the second partition 803, thereby enabling the molten mixture to pass through the separating device 8. This separating device 8 is used between the vacuum chamber and the extrusion chamber, so that when the molten mixture is moved into the extrusion chamber, the second partition 803 moves, and the telescopic pipe 805 can still complete the conveying of the molten mixture during the movement of the second partition 803, ensuring the stability of the pressure inside the extrusion chamber.

[0034] When extruding wire in the extrusion chamber, the spiral conveyor blade 5 rotates, and at the same time, the telescopic end of the second telescopic component 802 controls the movement of the second partition 803, which generates stable pressure on the material in the extrusion chamber, so that the material can be extruded in a stable pressure state. Afterwards, the external cooling device and winding device realize the cooling and collection of the wire.

[0035] The frame 1 contains at least two partition devices 8, which divide the interior of the frame 1 into three chambers: a stirring and melting chamber, a vacuum chamber, and an extrusion chamber. The number of chambers is related to the number of partition devices 8. In practical use, the number of partition devices 8 can be increased to increase the number of chambers and improve the effect of the original chambers. For example, two chambers can be set up for secondary stirring and melting or two chambers can be set up for secondary vacuuming. The vacuum pump 7 is a prior art device. The vacuum pump 7 achieves a vacuum state inside the frame 1 through the operation of an internal pump. The molten material is placed in a vacuum chamber. The vacuum pump 7 evacuates the vacuum chamber, making the inner wall of the vacuum chamber a vacuum state and maintaining the vacuum state, thereby sucking out the gas inside the molten material. By controlling the movement of the second partition 803, the internal volume of the vacuum chamber is controlled so that the internal volume of the vacuum chamber is greater than the volume of the molten material inside the vacuum chamber. This design can prevent the molten material from being extracted by the vacuum pump 7 during vacuuming. Moreover, the port of the vacuum pump 7 is located at the top of the vacuum chamber, and the molten material will not come into contact with the port under the influence of gravity.

[0036] To improve the rapid extraction of gas from the molten mixture, a folding stirring device 4 is installed inside the vacuum chamber. The folding stirring device 4 stirs the molten mixture to quickly extract the gas. Through the folding stirring device 4 and the dividing device 8, the frame 1 is divided into at least three chambers. Folding components are installed inside the stirring and melting chamber and the vacuum chamber. The folding components stir the mixture to quickly melt it. At the same time, the mixture is stirred in the vacuum chamber. The volatile components in the molten mixture generate gas, which is quickly extracted by the vacuum pump 7. This rapid removal of gas from the molten mixture ensures the quality of the wire after forming.

[0037] 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 embodiments and their equivalents.
