Description

Technical Field

[0001] The invention relates to the technical field of resin prepregs, and in particular to a device for preparing special resin prepregs. Background Art

[0002] Thermoplastic prepreg refers to a composition of a resin matrix and reinforcement made by impregnating continuous fibers or fabrics with thermoplastic resin under strictly controlled conditions. Impregnation is also called coating or dipping. At the same time, thermoplastic prepreg is also an intermediate material for manufacturing thermoplastic composite materials.

[0003] Compared to thermosetting prepregs, thermoplastic resins have very high viscosities, with the lowest viscosity exceeding 100 Pa.s at typical process temperatures. This makes coating and dipping difficult, and continuous fibers or fabrics are not easily penetrated. Currently, the melt impregnation method is widely used for the preparation of thermoplastic prepregs both domestically and internationally, and is primarily categorized into direct impregnation and melt extrusion impregnation.

[0004] A search revealed Chinese patent application number CN113334629A, which discloses a high-frequency vibration continuous fiber prepreg production device. The patent discloses two ultrasonic impregnation modules, each comprising a box-shaped body. The opposing surfaces of the two boxes serve as ultrasonic transmission surfaces. Within the box-shaped body are multiple ultrasonic transducers positioned sequentially along the feed direction. The output ends of the ultrasonic transducers contact the ultrasonic transmission surfaces via ultrasonic guide rods. The ultrasonic transducers, ultrasonic guide rods, and ultrasonic transmission surfaces work together to transmit ultrasonic waves to the continuous fibers passing between the two ultrasonic transmission surfaces, thereby promoting further impregnation of the continuous fibers with the resin thereon.

[0005] However, in actual use, in order to avoid fiber contamination, non-contact air coupling, electromagnetic coupling or laser coupling of the transducer is often used instead. However, each type of transducer has limitations such as continuous vibration of harmonic sound, resulting in large sound energy loss and weak signal. This in turn causes local harmonic frequency vibration energy to be unstable when the resin and fiber are impregnated, resulting in local pre-impregnation dispersion of the fiber material during the prepreg process and uneven impregnation of wide-width fiber cloth.

[0006] Therefore, the present application provides a special resin prepreg preparation device to meet the needs. Summary of the Invention

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, the air sound waves generated by setting a second transducer are vibrated and transmitted through the second vibrator. The second vibrator and the first vibrator are distributed vertically, and a connecting cavity-like structure is formed between the first vibrator and the second vibrator. The vibration waves generated by the second vibrator and the first vibrator form a connecting cavity-like structure between the first vibrator and the second vibrator, forming superimposed vibration waves. The superimposed vibration waves interact with each other to form a double-layer vibration wave of the second vibrator. The blocking of the supporting member forms a partition cavity inside the first installation cavity. The sound wave vibration is further superimposed on the sound wave vibration of the first vibrator and the second vibrator after concentrated reflection, and acts on the top of the infiltration cavity partition, so that the vibration in the infiltration cavity is more uniform, which effectively solves the limitations of large sound energy loss and weak signal caused by continuous vibration of harmonic sound.

[0022] By setting up multiple groups of mounting parts, support blocks, first compression parts, second compression parts and connecting parts to generate consistency of action, a stable effect can be achieved more quickly under external excitation conditions, and a preliminary stable effect can be achieved by only a concentric collision between the buffer part and one side of the second compression part. It is further arranged that one side of the second compression part and the buffer part are continuously compressed between the connecting part and one side of the first compression part so that the peak displacement and peak acceleration of the vibration provide different tuning stiffnesses, and the outer side of the resonant part acts on the bottom of the second vibrating part to ensure the vibration stability of the second vibrating part, thereby causing local harmonic frequency vibration energy to be unstable when the resin and the fiber are impregnated, resulting in local pre-impregnation dispersion of the fiber material and uneven impregnation of the wide-width fiber cloth during the prepreg process.

[0023] By setting the heat generated inside the heat storage part to act on the surface of the bending part to generate a corresponding bending force, the side of the bending part is bent, and the generated bending direction is the vector direction of the contact, and it contacts the surface of the contact to generate a piezoelectric signal. The piezoelectric signal generated by the contact is transmitted to the external cooler, and the input end of the external cooler receives the piezoelectric signal from the contact and starts working. Since a cooling pipe is provided inside the heat storage part, the cooling pipe and the external cooler are connected, and the cooling medium generated cools the heat storage part as a whole, thereby achieving the cooling of the first transducer and the second transducer. Compared with the existing technology of opening holes or fan heat dissipation, this scheme has a high degree of integration, effectively stores and dissipates heat, ensures the working efficiency of the first transducer and the second transducer, improves the service life of the first transducer and the second transducer, reduces the damage to the electrical components of the first transducer and the second transducer caused by the heat generated by the continuous operation of the second transducer and the first transducer, and increases the limiting infiltration efficiency.

[0024] By setting at least two air supply grooves and a second conveying channel, a side airflow is introduced in a forced suction manner to form a vortex airflow inside the blowing part. When the blowing part is working, the vortex airflow can, on the one hand, attract the external gas into the cover body and guide it to flow to the second conveying channel and at least two air supply grooves. On the other hand, the shielding of the vortex airflow can prevent the gas in the blowing part from escaping, thereby improving the positioning efficiency when positioning the fiber bundle. By setting the arc structure of the blowing part, the suction area of ​​the second conveying channel is increased to prevent the positioning deviation of the fiber bundle.

[0047] In this embodiment, if Figure 1As shown, an embodiment of the present invention provides a special resin prepreg preparation device, comprising: a support seat 1, a fiber spreading mechanism 2 for dispersing fibers is installed on the top of the support seat 1, a conveying roller group 3 for transporting the dispersed fibers is rotatably installed on one side of the fiber spreading mechanism 2, an impregnation cavity 4 for limited impregnation after dispersion is installed on one side of the conveying roller group 3, a drying box 5 for drying the impregnated fibers is fixed on one side of the impregnation cavity 4, a cooling box 6 for cooling the dried fibers is fixed on one side of the drying box 5, and a winding rack 7 for collecting the cooled fibers is fixed on one side of the cooling box 6. During use, The fiber material to be impregnated is placed on the roller on the top of the support seat 1 and is transmitted through a driving member (not shown in the figure), wherein the driving member is a motor belt structure in the prior art and is not described in detail. The fiber material to be impregnated is spread into bundles and preheated by the fiber spreading mechanism 2 to prevent the generation of lint on the fiber surface due to contact and friction with the fiber spreading mechanism 2 during fiber transmission, and the fiber bundles are transported to the impregnation cavity 4 for impregnation through the conveying roller group 3. After impregnation, the fiber bundles are dried and cooled respectively by the drying box 5 and the cooling box 6 to obtain the shaped and impregnated finished products, and are wound and dumped by the winding rack 7.

[0048] In this embodiment, if Figure 2-Figure 4 As shown, an interlayer plate is provided in the impregnation cavity 4 to form an interlayer at the bottom of the impregnation cavity 4, and a transducer mechanism 8 is installed inside the interlayer, wherein a compression roller is provided inside the impregnation cavity 4, and the roller can be arranged parallel up and down to compress and transport the fiber bundle to be impregnated while fully mixing the liquid inside the impregnation cavity 4 into the fiber bundle. It is worth noting that the inside of the impregnation cavity 4 is filled with a colloid, which is a resin.

[0049] Among them, the transducer mechanism 8 includes a first mounting cavity 81, a second mounting cavity 82 and a locking member 83. The first mounting cavity 81 and the second mounting cavity 82 are installed vertically. The locking member 83 is locked between the first mounting cavity 81 and the second mounting cavity 82 to fix the first mounting cavity 81 and the second mounting cavity 82. In another embodiment, the first mounting cavity 81 and / or the second mounting cavity 82 include but are not limited to a threaded rotation engagement mounting structure.

[0050] In this embodiment, if Figure 4As shown, a bearing member 801 is installed inside the first installation cavity 81, and a first transducer 84 is fixed on the top of the bearing member 801. The first transducer 84 is fixedly supported by the bearing member 801 to provide installation conditions for the first transducer 84. The bearing member 801 is located in the middle of the first installation cavity 81. The interior of the first installation cavity 81 is separated by the bearing member 801 to form a "U"-shaped structure, and is connected to the interior of the second installation cavity 82 and formed into a "U"-shaped structure. Furthermore, the top of the first transducer 84 A first vibrating member 85 is installed, a second transducer 86 is provided on the top of the first vibrating member 85, a second vibrating member 87 is installed on the top of the second transducer 86, the top of the second vibrating member 87 is in contact with the bottom of the partition plate inside the infiltration cavity 4, a sensing member 88 is fixed on one side of the inside of the first installation cavity 81, and resonance parts 89 are respectively installed on both sides of the bottom of the second vibrating member 87. During use, an external controller (not shown) is electrically connected to the first transducer 84 and the second transducer 86 respectively, and transmits electrical signals to the second transducer 87 respectively. The output ends of the first transducer 84 and the second transducer 86 generate air sound waves based on the acoustic energy signal. The air sound waves generated by the first transducer 84 are vibrated and transmitted via the first vibrating member 85. The air sound waves generated by the second transducer 86 are vibrated and transmitted via the second vibrating member 87. The second vibrating member 87 and the first vibrating member 85 are vertically distributed, and a connecting cavity-like structure is formed between one side of the first vibrating member 85 and the second vibrating member 87. The vibration waves generated by the second vibrating member 87 and the first vibrating member 85 are vibrated and transmitted via the first vibrating member 85 and the second vibrating member 87. A connected cavity-like structure is formed between one side of the moving part 87, forming a superimposed vibration wave. The interaction of the superimposed vibration waves causes the second vibrating part 87 to form a double-layer vibration wave. The blocking of the supporting part 801 forms a partition cavity inside the first installation cavity 81. The sound wave vibration is concentrated and reflected, and further superimposed on the sound wave vibration of the first vibrating part 85 and the second vibrating part 87, and acts on the top of the partition layer of the infiltration cavity 4, making the vibration in the infiltration cavity 4 more uniform, effectively solving the limitations of large sound energy loss and weak signal caused by continuous vibration of harmonic sound.

[0051] Furthermore, a sound-absorbing layer is evenly laid on the inner walls of the first installation cavity 81 and the second installation cavity 82, wherein the sound-absorbing layer solves the phenomenon of diffusion or reflection of air sound waves in the first installation cavity 81 and the second installation cavity 82. The material structure of the sound-absorbing layer includes but is not limited to foam and\or other materials that absorb sound waves.

[0052] The sensing element 88 detects the acoustic vibration inside the first mounting cavity 81 and / or the second mounting cavity 82 and feeds it back to an external display for display, and adjusts the current output ratio of the first transducer 84 and / or the second transducer 86 according to usage.

[0053] In this embodiment, if Figure 2-Figure 4 As shown, the resonating portion 89 is an annular cavity structure, a buffer part 891 is provided inside the resonating portion 89, a mounting part 892 is evenly and movably installed inside the resonating portion 89, one side of the mounting part 892 is in sliding contact with the surface of the buffer part 891, a number of supporting blocks 893 are evenly installed inside the resonating portion 89, a first compression part 894 is movably installed on one side of the supporting block 893, a connecting part 896 is connected to one side of the first compression part 894, a second compression part 895 is movably installed on one side of the connecting part 896, and one side of the second compression part 895 is in contact with the surface of the buffer part 891.

[0054] In this embodiment, if Figure 5 The second vibrating member 87 shown vibrates with the abutting surface of the interlayer of the infiltration cavity 4 during the double-layer superposition vibration process. During the vibration process, the resonating portion 89 generates a corresponding vibration force, causing the buffer 891 to generate a shaking force inside the resonating portion 89. During the shaking process of the buffer 891, one side of the mounting member 892 movably mounted inside the resonating portion 89 slides on the surface of the buffer 891, causing the buffer 891 to move in at least three directions. During the movement of the buffer 891, the position of the buffer 891 constantly changes, and at the same time, it continuously abuts against one side of the second compression member 895, causing one side of the second compression member 895 to synchronously and continuously pass through the second compression member 895. The other side of component 895 compresses one side of connecting component 896, and the force exerted on connecting component 896 drives one side of the first compression component 894 to continuously compress toward one side of support block 893, wherein the load-bearing stiffness and compression diameter of the second compression component 895 are greater than the stiffness and compression diameter of the first compression component 894. Since the mechanical strength and compression force exerted on the first compression component 894 are the sum of the second compression component 895, buffer component 891 and connecting component 896, the mechanical strength of the first compression component 894 itself must be sufficient to ensure fault tolerance, prevent the second compression component 895 from breaking and being damaged due to insufficient bearing force, and ensure that only a concentric collision occurs between the buffer component 891 and one side of the second compression component 895.

[0055] By setting up multiple groups of mounting parts 892, support blocks 893, first compression parts 894, second compression parts 895 and connecting parts 896 to generate consistency of action, a stable effect can be achieved more quickly under external excitation conditions, and a preliminary stable effect is achieved by only a concentric collision between the buffer part 891 and one side of the second compression part 895. It is further arranged that one side of the second compression part 895 and the buffer part 891 are continuously compressed between the connecting part 896 and one side of the first compression part 894, so that the peak displacement and peak acceleration of the vibration provide different tuning stiffnesses, and the outer side of the resonant part 89 acts on the bottom of the second vibrating part 87 to ensure the vibration stability of the second vibrating part 87, thereby causing local harmonic frequency vibration energy to be unstable when the resin is impregnated with the fiber, resulting in local prepreg dispersion of the fiber material and uneven impregnation of the wide-width fiber cloth during the prepreg process.

[0056] In another embodiment, the interior of the resonating portion 89 is filled with fluid, which includes but is not limited to a magnetic medium. The magnetic flow through the medium continuously impacts the surface of the buffer member 891, causing it to be displaced. The above structure can be used as an anti-vibration structure for installing the first mounting cavity 81 and the second vibrating member 87 and the second mounting cavity 82.

[0057] The internal installation of the mounting member 892 and the resonating portion 89 includes but is not limited to a ball-and-shaft connection.

[0058] This solution has a compact structure, is easy to implement, and is easy to use. It effectively reduces the number of replacements due to cracking of the pipe wall and reduces the cost of use.

[0059] In this embodiment, if Figure 3 、 Figure 6As shown, one side of the first energy conversion member 84 and the second energy conversion member 86 passes through the first mounting cavity 81 and the second mounting cavity 82 and is connected to a heat conducting member 91. The first energy conversion member 84 and the second energy conversion member 86 are thermally connected to the heat conducting member 91 to transfer the heat generated by the first energy conversion member 84 and the second energy conversion member 86 to the heat conducting member 91. A heat storage portion 9 is fixed to one side of the first mounting cavity 81 and the second mounting cavity 82. The other side of the heat conducting member 91 is installed in the interior of the heat storage portion 9. The interior of the heat storage portion 9 is vertically parallel and is respectively provided with a baffle 92 and a bent member 94. One side of the baffle 92 is filled with a flowing medium. A bent member 94 is provided on one side of the interior of the heat storage portion 9. The baffle 92 and the bent member 94 are It is bidirectionally movable, and one side of the bending part 94 can be bent. When the bending part 94 is in the open state, the baffle 92 is in the closed state. An energy storage part 93 is provided inside the heat storage part 9, and the energy storage part 93 is composed of a honeycomb-shaped thermal insulation material. The present invention utilizes the energy storage part 93 to be composed of a honeycomb-shaped thermal insulation material, and the volume can be reduced by more than half, and can even be reduced to 1 / 10 of the traditional heat storage volume, so that it can be designed as a compact energy storage system, reducing costs, protecting the mechanical integrity of the heat storage part 9, and improving high temperature resistance and compressive strength. A contact 95 is installed inside the heat storage part 9, and the surface on one side of the contact 95 and the surface on one side of the bending part 94 can abut, and the contact 95 is connected to the external cooler for communication.

[0060] In the above scheme, if Figure 6 As shown, the heat generated by the first transducer 84 and the second transducer 86 is transferred to the heat conductor 91, and heat energy is transferred inside the heat storage part 9 and inside the baffle 92. The heat transferred by the heat conductor 91 is stored by the energy storage part 93. The heat generated inside the heat storage part 9 acts on the surface of the bending part 94 to generate a corresponding bending force, so that the side of the bending part 94 bends. The generated bending direction is the vector direction of the contact 95, and it contacts the surface of the contact 95 to generate a piezoelectric signal. The piezoelectric signal generated by the contact 95 is transmitted to the external cooler. The input end of the external cooler receives the piezoelectric signal from the contact 95 and generates Working, since a cooling pipe is provided inside the heat storage part 9, and the cooling pipe is connected to the external cooler, the cooling medium generated cools the heat storage part 9 as a whole, thereby cooling the first energy conversion element 84 and the second energy conversion element 86. Compared with the opening or fan heat dissipation in the prior art, this solution has a high degree of integration, effectively stores and dissipates heat, ensures the working efficiency of the first energy conversion element 84 and the second energy conversion element 86, improves the service life of the first energy conversion element 84 and the second energy conversion element 86, and reduces the damage to the electrical components of the first energy conversion element 84 and the second energy conversion element 86 caused by the heat generated by the continuous operation of the second energy conversion element 86 and the first energy conversion element 84.

[0061] In this embodiment, the first transducer 84 and the second transducer 86 are transducer elements that convert electrical energy into acoustic energy, and generate acoustic waves through mechanical vibration.

[0062] In this embodiment, if Figure 7-Figure 9 As shown, the fiber spreading mechanism 2 includes a fiber spreading roller 21, a heating component 22 and a support roller 23. The surface of the fiber spreading roller 21 is provided with several protrusions, and the surface of the support roller 23 is smooth. A blowing portion 27 is provided in parallel at the bottom of the support roller 23, and at least two air supply grooves are provided inside the blowing portion 27. The bottom of the blowing portion 27 is connected to a first conveying channel 28, and several second conveying channels 29 are symmetrically opened on both sides of the bottom of the other side of the blowing portion 27, and are connected to at least two air supply grooves. A telescopic part 24 is fixed on one side of the heating component 22, and a first connecting part 25 is movably installed at one end of the telescopic part 24. Second connecting parts 26 are respectively installed on both sides of the fiber spreading roller 21, and one side is in an arc-shaped structure and is adapted to one side of the first connecting part 25.

[0063] In the above scheme, during use, the fiber material to be impregnated is placed on the roller on the top of the support seat 1 and the fiber material to be impregnated is spread and transported through the protrusions on the surface of the fiber spreading roller 21, wherein the protrusions on the surface of the fiber spreading roller 21 are adjustable, and fibers of different materials are dispersed and processed into bundles, and the surface of the heating component 22 is preheated to prevent the contact and friction with the fiber spreading roller 21 during the fiber spreading and transmission to produce lint on the fiber surface, and then transported through the support roller 23 installed on one side of the heating component 22, and transferred through the conveying roller group 3 for subsequent impregnation operations. When the fiber bundle after fiber spreading passes between the conveying roller group 3 and the support roller 23, the blowing part 27 at the bottom end of the support roller 23 sucks air into the bundle, so that the bundle always remains in a parallel position, preventing the bundle from being offset during transportation and causing the bundle to be dispersed.

[0064] In this embodiment, Figure 8 As shown, when the fiber spreading roller 21 is transporting the wire harness, the first connecting member 25 on one side is driven isotropically by the telescopic drive of the output end of the telescopic member 24 installed on one side of the heating component 22. When the first connecting member 25 moves in the vector direction of the second connecting member 26 installed on one side of the fiber spreading roller 21, one side of the first connecting member 25 presses against one side of the fiber spreading roller 21 and moves in an arc shape inside the second connecting member 26, so that the fiber spreading roller 21 is lifted up, and vice versa, it is lowered to adjust the tension of the wire harness on the surface of the fiber spreading roller 21.

[0065] It is worth noting that in the above solution, the telescopic member 24 includes but is not limited to equipment structures that can move linearly, such as a cylinder and an electric cylinder.

[0066] In this embodiment, Figure 9 The direction indicated by the arrow is the direction of air flow.

[0067] In this embodiment, if Figure 7 、 Figure 9 As shown, the first conveying channel 28 and at least two air supply grooves provided in the blowing part 27 are respectively connected to the external suction equipment by pipes. At least two air supply grooves generate corresponding suction force in the groove through the external suction equipment, and at the same time, the first conveying channel 28 also generates corresponding suction force through the external suction equipment. The two-way adsorption of the second conveying channel 29 enables the external suction equipment to be provided with auxiliary airflow along the at least two air supply grooves and the second conveying channel 29. Figure 9 The air flow direction indicated by the arrow is passed into the first conveying channel 28 in a perpendicular or intersecting direction to strengthen the vortex airflow. Furthermore, by setting at least two air supply grooves and a second conveying channel 29, the side airflow is introduced in a forced suction manner to form a vortex airflow inside the blowing part 27. When the blowing part 27 is working, the vortex airflow can, on the one hand, attract the external gas into the cover body and guide it to flow to the second conveying channel 29 and at least two air supply grooves. On the other hand, through the shielding of the vortex airflow, it can prevent the gas in the blowing part 27 from escaping, thereby improving the positioning efficiency when positioning the fiber bundle. The suction area of ​​the second conveying channel 29 is increased by setting the arc structure of the blowing part 27 to prevent the positioning deviation of the fiber bundle.

[0068] In this embodiment, the heating method of the heating component 22 includes but is not limited to electric heating, water circulation heating and other heating methods. The surface of the support roller 23 is a smooth structure, which can increase the fiber passing efficiency after fiber spreading, reduce the friction coefficient, and further prevent the occurrence of lint.
