Description

Technical Field

[0001] This invention relates to the field of PEEK composite material technology, and in particular to a continuous extrusion molding equipment and molding method for impact-resistant PEEK composite materials. Background Technology

[0002] PEEK composite material is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. It can be manufactured into various mechanical parts, such as automotive gears, oil screens, and shift starter discs. It has been widely used in aerospace, military, medical and automotive fields. PEEK composite material can be stored at room temperature, which makes it possible to produce large structures without time restrictions. PEEK composite material has high impact damage tolerance and its residual compressive strength after impact is greater than that of thermosetting composite material. Furthermore, thermoplastic composite material has good hot compressive strength and can replace thermosetting composite material to a certain extent. PEEK composite material can be made into products with complex shapes and precise dimensions. It has good environmental adaptability, is resistant to humid heat aging, acid and alkali corrosion, salt spray, and mildew.

[0003] PEEK composite materials are generally made by combining PEEK and carbon fiber. PEEK, as a typical high-performance thermoplastic resin, has outstanding properties. When combined with continuous carbon fiber, the properties of the two materials are effectively combined, resulting in superior overall performance. However, existing technologies lack equipment capable of continuous extrusion molding and mixing. If ordinary extrusion molding equipment is used, it is impossible to uniformly mix carbon fiber and resin during the extrusion process. Generally, raw materials need to be manually mixed before extrusion, which affects processing efficiency. Therefore, this invention proposes an impact-resistant continuous extrusion molding equipment and molding method for PEEK composite materials to solve the problems existing in the prior art.

[0015] A continuous extrusion molding method for impact-resistant PEEK composite materials includes the following steps:

[0016] S1: Start the motor base to drive the first spiral shaft to rotate, and transport the heated and molten resin raw material in the resin raw material bin to the mixing pipe through the first conveying pipe;

[0017] S2: Start the second spiral shaft to transport the carbon fiber raw material in the carbon fiber raw material bin downwards, and enter the mixing chamber together with the resin raw material;

[0022] The beneficial effects of this invention are as follows:

[0023] 1. In this invention, heated and molten resin raw material is transported to the mixing pipe through the first conveying pipe, and carbon fiber raw material is simultaneously transported down the mixing pipe. The carbon fiber raw material and resin raw material enter the mixing chamber together for mixing. The diameter of the mixing chamber is reduced by the diameter adjustment component to slow down the flow rate of the raw material. In conjunction with the ultrasonic generator, the raw material is ultrasonically mixed during this process, which is beneficial for homogenization of the raw material and uniform dispersion during the extrusion molding process, maintaining continuity.

[0024] 2. In this invention, after extrusion molding, the molded raw material is fed into the spraying chamber and passes between the upper and lower coating rollers. The lower coating roller coats the bottom of the raw material with zirconia coating from the zirconia coating chamber. A synchronous pressure pump transports the zirconia coating from the zirconia coating chamber to the nozzle through a suction pipe and conduit, spraying it onto the upper coating roller and coating the top of the raw material. Then, it is dried and solidified. By utilizing the characteristics of zirconia coating, the overall impact resistance of the raw material is improved, and the product quality is optimized.

[0025] 3. In the process of conveying the molten resin raw material through the first conveying pipe after heating, the sliding plate moves to drive the sleeve to be placed on the outside of the first conveying pipe. The heating wire heats the first conveying pipe to ensure the moltenness of the resin raw material inside. During the extrusion molding process, the material is shaped by the sizing nozzle.

[0033] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example 1

[0034] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a continuous extrusion molding equipment for impact-resistant PEEK composite materials, including a workbench 1 and a first conveying pipe 2. The first conveying pipe 2 is located above the workbench 1, and a mixing pipe 3 is provided at the output end of the first conveying pipe 2. A second conveying pipe 4 is provided at the middle of the upper part of the workbench 1. The output end of the mixing pipe 3 is connected to the second conveying pipe 4. A resin raw material silo 5 is connected to one side of the top of the first conveying pipe 2. A carbon fiber raw material silo 6 is connected to the upper part of one side of the mixing pipe 3. A diameter adjustment component is provided at the lower part of one side of the mixing pipe 3, and a mixing chamber 19 is provided at the lower part of the interior of the mixing pipe 3. An ultrasonic generator 7 is provided on one side of the mixing chamber 19, and a shaping component is provided on one side of the second conveying pipe 4.

[0035] A spraying chamber 8 is provided on one side of the top of the workbench 1, and a zirconia coating chamber 9 is provided below the interior of the spraying chamber 8. A lower coating roller 10 is rotatably provided inside the spraying chamber 8 above the zirconia coating chamber 9. A support 11 is provided above the interior of the spraying chamber 8, and an upper coating roller 12 is rotatably provided below the support 11. A nozzle 13 is provided on the support 11, and the nozzle 13 is connected to the zirconia coating chamber 9 through a connecting part. A drying part is provided on one side of the top of the spraying chamber 8. In use, heated and molten resin raw material is conveyed to mixing pipe 3 through first conveying pipe 2. Simultaneously, carbon fiber raw material is conveyed from mixing pipe 3 and mixed together with resin raw material into mixing chamber 19. The diameter of mixing chamber 19 is reduced by diameter adjustment component to slow down the flow speed of raw material. With the help of ultrasonic generator 7, the raw material is ultrasonically mixed during this process, which is beneficial to homogenization of raw material and uniform dispersion during extrusion molding. After extrusion molding by shaping component, the molded raw material is sent to spraying chamber 8 and passes between upper brush roller 12 and lower brush roller 10. Lower brush roller 10 coats the bottom of raw material with zirconia coating in zirconia coating chamber 9. Simultaneous pressure pump 32 conveys zirconia coating in zirconia coating chamber 9 to nozzle 13 through suction pipe 33 and conduit 31, sprays it onto upper brush roller 12, coats the top of raw material, and then dries and solidifies. The characteristics of zirconia coating are used to improve the overall impact resistance of raw material.

[0036] The drying section includes a fan 14 and a heating grid. The heating grid is located at the input end of the fan 14, and the output end of the fan 14 extends into the interior of the spraying chamber 8. The coated material passes through the output range of the fan 14, is heated by the heating wire, and the fan 14 blows out hot air to dry and solidify the coating.

[0037] The first conveying pipe 2 has a first rotatable spiral shaft 15 inside. A motor base 16 is located on one side of the workbench 1, and the output end of the motor base 16 is connected to the first spiral shaft 15. The mixing pipe 3 has a second rotatable spiral shaft 17 inside, and the second conveying pipe 4 has a third rotatable spiral shaft 18 inside. Both the second spiral shaft 17 and the third spiral shaft 18 are driven to rotate by a motor. In use, the raw materials are conveyed by the rotation of the first spiral shaft 15, the second spiral shaft 17, and the third spiral shaft 18.

[0038] The caliber adjustment assembly includes a control box 20 and a partition 22. One side of the control box 20 communicates with the mixing chamber 19 via a passage cavity 21. The partition 22 is movably disposed within the passage cavity 21 and is adapted to the mixing chamber 19. A drive chamber 23 is located on the side of the control box 20 away from the passage cavity 21. A nut tube 24 is located on one side of the partition 22, extending into the drive chamber 23. A threaded rod 25 is rotatably disposed inside the drive chamber 23, threadedly adapted to the nut tube 24. The threaded rod 25 is driven to rotate by a motor. Guide rails 26 are located at both ends of the drive chamber 23. Guide blocks 27 adapted to the guide rails 26 are located on one side of both ends of the nut tube 24. A sealing filler 28 is located at the point where the nut tube 24 passes through the passage cavity 21 and the drive chamber 23. In use, the motor drives the threaded rod 25 to rotate, pushing the nut tube 24 to move. The guide block 27, along the guide rail 26, improves the stability of movement, allowing the partition 22 to move into the mixing chamber 19, reducing the diameter of the mixing chamber 19, slowing down the flow of raw materials, and starting the ultrasonic generator 7. During this process, the raw materials are ultrasonically mixed.

[0039] Both ends of the bottom of the support 11 are hinged with spring arms 29, and a spring 30 is connected between the upper part of the spring arms 29 and the support 11. The upper coating roller 12 is rotatably positioned between the two sets of spring arms 29. The shaped raw material enters the spraying chamber 8 and passes between the upper coating roller 12 and the lower coating roller 10. The spring 30 compresses the spring arms 29, causing the upper coating roller 12 to press down on the raw material, resulting in the upper coating roller 12 and the lower coating roller 10 adhering to the raw material for coating.

[0040] The connecting part includes a conduit 31 and a pressure pump 32. The conduit 31 is connected above the nozzle 13, and the pressure pump 32 is located on one side of the spraying chamber 8. The input end of the conduit 31 is connected to the pressure pump 32, and the input end of the pressure pump 32 is connected to a suction tube 33. The lower end of the suction tube 33 is connected to the zirconia coating chamber 9. The shaped raw material enters the spraying chamber 8 and passes between the upper coating roller 12 and the lower coating roller 10. The lower coating roller 10 coats the zirconia coating in the zirconia coating chamber 9 onto the bottom of the raw material. Simultaneously, the pressure pump 32 starts and transports the zirconia coating in the zirconia coating chamber 9 to the nozzle 13 through the suction tube 33 and the conduit 31, spraying it onto the upper coating roller 12 and coating the top of the raw material.

[0041] The shaping assembly includes a shaping nozzle 34, a metal plate 35, and a semiconductor plate 36. The semiconductor plate 36 is disposed outside the shaping nozzle 34, and the metal plate 35 is disposed outside the semiconductor plate 36. The metal plate 35 is connected to a power source. Raw material is fed to the shaping nozzle 34 and extruded. During this process, the metal plate 35 is energized, and the semiconductor plate 36 is cooled, causing the raw material to cool and solidify. The metal plate 35 and the semiconductor plate 36 are in contact, forming a Schottky junction. When driven by electricity, one side heats up and the other side cools down due to the principle of electron movement. Together with the semiconductor plate 36, the Peltier effect is formed, which cools the metal. The principle of the Schottky junction is that the work function of the semiconductor is generally smaller than that of the metal. Therefore, when the metal and the semiconductor are in contact, electrons flow from the semiconductor into the metal, forming a space charge region composed of positively charged, immobile impurity ions in the surface layer of the semiconductor. The principle of the Peltier effect is that when current flows through a circuit composed of different conductors (metal and semiconductor), in addition to generating irreversible Joule heating, heat absorption and heat release phenomena will occur at the junction of different conductors depending on the direction of the current, thereby achieving cooling.

[0042] A plate 37 is provided on the workbench 1 located below the first conveying pipe 2, and guide rods 38 are provided on both sides of the plate 37. Slide plates 39 are movably mounted on both ends of the guide rods 38. Each of the two slide plates 39 is provided with a sleeve 40 adapted to the first conveying pipe 2, and a heating wire 41 is provided inside the sleeve 40. A bidirectional screw rod 42 is rotatably mounted on the middle of the plate 37, and the bidirectional screw rod 42 is driven by a motor. Nut blocks adapted to the threads at both ends of the bidirectional screw rod 42 are respectively provided under the two slide plates 39. During the process of conveying the molten resin material through the first conveying pipe 2, the bidirectional screw rod 42 drives the two sets of slide plates 39 to move relative to each other along the guide rods 38, causing the two sets of sleeves 40 to be mounted on the outside of the first conveying pipe 2. The heating wire 41 heats the first conveying pipe 2, ensuring the moltenness of the resin material inside. Example 2

[0043] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a continuous extrusion molding method for impact-resistant PEEK composite materials, including the following steps:

[0044] S1: Start the motor base 16 to drive the first spiral shaft 15 to rotate, and transport the heated and melted resin raw material in the resin raw material bin 5 to the mixing pipe 3 through the first conveying pipe 2;

[0045] S2: Start the second spiral shaft 17 to transport the carbon fiber raw material in the carbon fiber raw material bin 6 down and into the mixing chamber 19 together with the resin raw material;

[0046] S3: The threaded rod 25 rotates, pushing the nut tube 24 to move, causing the partition 22 to move into the mixing chamber 19, reducing the diameter of the mixing chamber 19, slowing down the flow of raw materials, and starting the ultrasonic generator 7 to ultrasonically mix the raw materials during this process;

[0047] S4: The mixed raw materials enter the second conveying pipe 4, and the third spiral shaft 18 is started to convey the raw materials to the shaping nozzle 34 and extrude them. During this process, the metal plate 35 is energized and the semiconductor plate 36 is cooled, so that the raw materials are cooled and shaped.

[0048] S5: The shaped raw material enters the spraying chamber 8 and passes between the upper coating roller 12 and the lower coating roller 10. The lower coating roller 10 coats the zirconia coating in the zirconia coating chamber 9 onto the bottom of the raw material. The synchronous pressure pump 32 starts and transports the zirconia coating in the zirconia coating chamber 9 to the nozzle 13 through the suction pipe 33 and the guide pipe 31, and sprays it onto the upper coating roller 12 to coat the top of the raw material.

[0049] S6: The coated material passes through the output range of fan 14, is heated by heating wire, and fan 14 blows out hot air to dry and solidify the coating.

[0050] This invention delivers heated and molten resin raw material to mixing pipe 3 via first conveying pipe 2. Simultaneously, carbon fiber raw material is delivered from mixing pipe 3 and enters mixing chamber 19 together with the resin raw material for mixing. The diameter of mixing chamber 19 is reduced by the orifice adjustment component to slow down the flow rate of the raw material. In conjunction with ultrasonic generator 7, the raw material is ultrasonically mixed during this process, which is beneficial for homogenization of the raw material and uniform dispersion during extrusion molding, maintaining continuity. After extrusion molding, the molded raw material is sent to spraying chamber 8, passing between upper coating roller 12 and lower coating roller 10. Lower coating roller 10 coats the bottom of the raw material with zirconia coating from zirconia coating chamber 9. Simultaneously, pressure pump 32 delivers the zirconia coating from zirconia coating chamber 9 to nozzle 13 through suction pipe 33 and conduit 31, spraying it onto upper coating roller 12 and coating the top of the raw material. Then, it is dried and solidified. Utilizing the properties of zirconia coating, the overall impact resistance of the raw material is improved, optimizing product quality. Meanwhile, during the process of conveying the molten resin raw material through the first conveying pipe 2 after heating, the slide plate 39 moves to drive the sleeve 40 to be fitted on the outside of the first conveying pipe 2, and the heating wire 41 heats the first conveying pipe 2 to ensure the moltenness of the resin raw material inside. During the extrusion molding process, the material is shaped by the shaping nozzle 34, and the metal plate 35 is energized and the semiconductor plate 36 is cooled, so that the raw material is cooled and shaped. This is conducive to accurate control of heating and cooling, and has diversified functions.

A continuous extrusion molding method for impact-resistant PEEK composite materials, characterized in that, Includes the following steps: S1: Start the motor base (16) to drive the first spiral shaft (15) to rotate, and transport the heated and melted resin raw material in the resin raw material bin (5) to the mixing pipe (3) through the first conveying pipe (2); S2: Start the second spiral shaft (17) to transport the carbon fiber raw material in the carbon fiber raw material bin (6) down and enter the mixing chamber (19) together with the resin raw material. S3: The threaded rod (25) rotates, pushing the nut tube (24) to move, causing the partition (22) to move into the mixing chamber (19), reducing the diameter of the mixing chamber (19), slowing down the flow of raw materials, and starting the ultrasonic generator (7) to ultrasonically mix the raw materials during this process; S4: The mixed raw material enters the second conveying pipe (4), the third spiral shaft (18) is started, and the raw material is conveyed to the shaping nozzle (34) and extruded. During this process, the metal plate (35) is energized and the semiconductor plate (36) is cooled, so that the raw material is cooled and shaped. S5: The shaped raw material enters the spraying chamber (8) and passes between the upper brush roller (12) and the lower brush roller (10). The lower brush roller (10) coats the zirconia coating in the zirconia coating chamber (9) onto the bottom of the raw material. The synchronous pressure pump (32) is started and transports the zirconia coating in the zirconia coating chamber (9) to the nozzle (13) through the suction pipe (33) and the conduit (31) to spray onto the upper brush roller (12) and coat the top of the raw material. S6: The coated material passes through the output range of the fan (14), is heated by the heating wire, and the fan (14) blows out hot air to dry and solidify the coating.
