Description

Technical Field

[0001] The present invention relates to the technical field of fiber forming equipment, and specifically provides an automated multi-station fiber forming equipment and its forming method. Background Art

[0002] Fiber forming equipment is the core equipment that converts various fiber raw materials into basic fiber structures such as filaments, fiber webs, and prepregs through processes such as spinning and carding, solving the preliminary forming of "raw materials to fiber materials"; while the compression molding equipment, on this basis, uses a mold as a carrier to further process the fiber material into a product with a complex three-dimensional structure by applying pressure, achieving the key leap of "fiber material to end product". The fiber compression molding equipment uses mold constraints and pressure drive to endow the fiber material with a precise three-dimensional shape, strengthen the interfacial bonding of the material, and achieve high-volume production.

[0003] However, in the prior art, the design of each functional module of traditional fiber forming equipment is scattered, lacking a systematic linkage mechanism. The slurry mixing link and the forming link of the equipment are completed by independent devices respectively. After the mixing equipment finishes stirring the slurry, it is necessary to transfer the slurry to the forming station manually or semi-automatically. There are time delays and position deviations in this process; at the same time, traditional equipment cannot achieve multiple links to respond synergistically triggered by one action, resulting in idle waiting time between processes, leading to a decrease in production efficiency. In terms of efficiency, non-continuous operation lengthens the production beat. In terms of cost, frequent manual intervention or semi-automatic transfer increases labor costs and equipment energy consumption; in terms of quality, precipitation and stratification are likely to occur during the static waiting of the slurry for forming, and the shaking during transfer may damage the mixing uniformity, resulting in an increase in the product defect rate. Summary of the Invention

The third connecting pipe is fixedly connected to the waste liquid storage tank. A fiber slurry filtering component is arranged inside the waste liquid storage tank, and a drain pipe is fixedly connected to the bottom of the waste liquid storage tank. A valve is installed on the surface of the drain pipe.

[0011] Preferably, a pre-pressing module mechanism is arranged inside the slurry tank component. A pre-pressing mechanism and a feeding mechanism are respectively installed on the upper part of the moving mechanism. The feeding mechanism is located on one side of the pre-pressing mechanism.

[0012] Preferably, the moving mechanism includes a second fixed frame. A servo moving component is fixedly connected to the upper part of the second fixed frame.

A second industrial camera is installed on the side of the pre-pressing and forming die, and a pressure sensor is installed at the bottom of the pre-pressing and forming die.

[0013] Preferably, the feeding mechanism includes a lifting frame component. An angle adjustment component is fixedly connected to the surface of the lifting frame component. And an adsorption component is rotatably connected to the lower part of the lifting frame component. The angle adjustment component is used to adjust the horizontal angle of the adsorption component. The adsorption component is used to adsorb and feed the pre-pressed fiber products.

[0014] Preferably, the forming mechanism includes a first fixed frame. A cam divider is fixedly connected to the bottom of the first fixed frame. And a first mounting frame is rotatably connected to the upper part of the first fixed frame. A plurality of first compression components are installed on the top of the first mounting frame. A first forming die is installed at the bottom of the first compression component. A plurality of second forming dies are installed on the surface of the first mounting frame. The second forming dies are located below the first forming die. A first industrial camera is arranged on the side of the second forming die. The first industrial camera is installed on the surface of the first mounting frame. The cam divider is used to drive the first mounting frame to rotate. An encoder is installed on the upper part of the first mounting frame. The encoder is used to monitor the rotation angle of the first mounting frame.

[0015] A forming method for an automated multi-station fiber forming device includes the following steps:

[0016] S1. An external fiber slurry feeding device injects fiber slurry into the inner box of the slurry tank assembly. Subsequently, the inner box is driven to move upward by the lifting mechanism, so that the fiber slurry in the inner box contacts the surface of the pre-pressing and feeding die.

[0017] S2. By starting the vacuum pump, suction is generated on the contact surface between the pre-pressing and feeding die and the fiber slurry through the first connecting pipe, and the fibers in the fiber slurry are adsorbed onto the surface of the pre-pressing and feeding die. Subsequently, the pre-pressing and feeding die is driven to flip by the flipping component, and the pre-pressing mechanism is used to pre-press the fiber slurry.

[0018] S3. Then, the pre-pressed material is placed on the second forming die by the feeding mechanism for forming processing.

[0019] S4. The pre-pressing and feeding die is driven to flip by the flipping component. During the process of pre-pressing and forming the fiber slurry on the surface of one pre-pressing and feeding die by the moving mechanism, the other pre-pressing and feeding die simultaneously performs the adsorption operation of the slurry under the action of the cloth feeding mechanism.

[0020] S5. When the feeding mechanism is feeding the pre-pressed material inside a pre-pressing feeding mold, the flipping assembly drives the other pre-pressing feeding mold that has completed the slurry feeding to flip. At the same time, after the feeding mechanism feeds the pre-pressed material to the upper part of a No. 2 molding mold on the surface of the No. 1 mounting frame, the No. 1 mounting frame is driven to rotate through the cam divider, and the other No. 2 molding mold is moved to the end of the feeding mechanism, in preparation for the final pressing operation of the pre-pressed material again.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, when the servo motor drives the No. 1 lead screw to drive the inner box to rise and fall, the No. 2 lead screw is linked by the synchronous belt to move the mixing frame in the inner box; at the same time, the high-pressure air generated by the vacuum pump is introduced into the mixing frame through the No. 4 connecting pipe to realize the dynamic mixing of the fiber slurry, improve the fiber uniformity, thereby improving the molding quality of the product, and completing the integration of slurry mixing and adsorption. The moving mechanism cooperates with the lifting mechanism to make the inner box accurately dock with the pre-pressing feeding mold. After the flipping assembly completes the mold flipping, the No. 2 compression assembly drives the pre-pressing molding mold to realize pre-pressing. The adsorption assembly cooperates with the servo moving assembly and the lifting frame assembly to transfer the pre-pressed material to the No. 1 molding mold and the No. 2 molding mold to complete the final molding, forming an "adsorption-pre-pressing-molding" assembly line to improve processing efficiency;

[0023] 2. In the present invention, when the lifting mechanism is used to drive the inner box to reset, the No. 2 lead screw and the No. 2 wire block are linked to drive the mixing rack, so that the laser thickness gauge can scan the fiber slurry on the surface of the pre-pressing feeding mold to ensure the adequacy of data collection and detect the thickness in real time. When the detection value exceeds the standard, the adsorption time of the vacuum pump is dynamically adjusted to accurately control the slurry adsorption amount to ensure that the thickness tolerance is maintained within the standard. In the pre-pressing link, the servo moving component cooperates with the No. 2 industrial camera to collect the position information of the pre-pressing feeding mold. After calculation by the control system, the No. 2 compression component drives the pre-pressing molding mold to press down, and the pressure sensor monitors the pre-pressing pressure in real time to ensure uniform pre-pressing density;

[0024] 3. In the present invention, the synchronous operation of the double pre-pressing feeding die is achieved through the flipping component. When the moving mechanism performs pre-pressing forming on one of them, the other die synchronously completes the slurry adsorption through the cloth feeding mechanism. In cooperation with the linkage of the feeding mechanism and the cam divider, the second forming die on the first mounting frame is rotated to access the final pressing process, improving the efficiency. At the same time, the fiber waste liquid generated during the vacuum pump adsorption process is introduced into the waste liquid storage tank through the first connecting pipe and separated and recycled through the internal filtering component, avoiding material loss. When the pressure of the vacuum pump is insufficient, the booster pump automatically supplements the pressure to ensure that the mixing rack obtains sufficient air pressure to maintain the uniformity of slurry mixing. At the same time, the pressure difference is used to accelerate the waste liquid filtration, realizing a closed loop of "production - recycling - reuse", improving the processing efficiency, reducing material loss, and enhancing the comprehensive energy efficiency, which is applicable to the continuous and large-scale production of high-precision fiber products.

The cloth feeding mechanism 7 is used to make the preloading feeding die 62 generate suction, and the cloth feeding mechanism 7 provides power for the auxiliary mechanism 10 to mix the fiber slurry;

[0037] The fabric mechanism 7 includes a waste liquid storage tank 71, a first connecting pipe 73 and a second connecting pipe 74. A vacuum pump 72 is connected to the side of the waste liquid storage tank 71 through the second connecting pipe 74. The vacuum pump 72 is connected to the pre-pressing feeding die 62 through the first connecting pipe 73. The auxiliary mechanism 10 consists of a position adjusting component and a fourth connecting pipe 110. The fourth connecting pipe 110 is fixedly connected to the top of the waste liquid storage tank 71, and a mixing frame 111 is fixedly connected to the end of the fourth connecting pipe 110. The mixing frame 111 blows air into the inner box to mix the fiber slurry. A lifting mechanism 4 is fixedly connected to the outside of the moving mechanism 3. The lifting mechanism 4 is used to drive the inner box to move up and down, so that the fiber slurry in the inner box contacts the surface of the pre-pressing feeding die 62. And the lifting mechanism 4 drives the position adjusting component to drive the mixing frame 111 to move in the inner box.

[0038] The lifting mechanism 4 includes a third fixing frame 41. A servo motor 42 is fixedly connected to the surface of the third fixing frame 41. The output end of the servo motor 42 is fixedly connected to a first lead screw 43. A first lead screw block 44 is threadedly connected to the surface of the first lead screw 43. A connecting frame 45 is fixedly connected to the surface of the first lead screw block 44. A second mounting frame 46 is fixedly connected to the side of the connecting frame 45. The second mounting frame 46 is fixedly connected to the bottom of the inner box. The position moving component includes a first synchronous pulley 101, a first connecting shaft 104, a second lead screw 107 and a third mounting frame 108. The first synchronous pulley 101 is fixedly connected to the first lead screw 43. One end of the first connecting shaft 104 is fixedly connected to a second synchronous pulley 103, and the other end of the first connecting shaft 104 is fixedly connected to a first bevel gear 105. A synchronous belt 102 is movably connected to the surfaces of the second synchronous pulley 103 and the first synchronous pulley 101. One end of the second lead screw 107 is fixedly connected to a second bevel gear 106. The second bevel gear 106 meshes with the first bevel gear 105. The second lead screw 107 is rotatably connected to the third mounting frame 108, and a second lead screw block 109 is threadedly connected to the surface of the second lead screw 107. The second lead screw block 109 is fixedly connected to the mixing frame 111.

[0039] In this embodiment, an external fiber slurry feeding device injects fiber slurry into the inner box of the slurry tank assembly 5. Subsequently, the servo motor 42 drives the first lead screw 43 to rotate, driving the first lead screw block 44 and the connecting frame 45 to move upward. At this time, the second mounting frame 46 will push the inner box upward, so that the fiber slurry in the inner box contacts the surface of the pre-pressing feeding die 62. During the process of the pre-pressing feeding die 62 contacting the fiber slurry, the vacuum pump 72 is started to generate suction on the contact surface between the pre-pressing feeding die 62 and the fiber slurry through the first connecting pipe 73, adsorbing the fibers in the fiber slurry onto the surface of the pre-pressing feeding die 62. Subsequently, the turning assembly 61 drives the pre-pressing feeding die 62 to turn over, and the lifting mechanism 4 drives the inner box to move downward. After the pre-pressing feeding die 62 with the fiber material is turned over, the second compression assembly 81 pushes the pre-pressing die 82 to pre-press the fiber material inside the pre-pressing feeding die 62. After pre-pressing, the second compression assembly 81 drives the pre-pressing die 82 to move upward. At the same time, the servo moving assembly 32 moves the adsorption assembly 92 above the pre-pressing feeding die 62, and the lifting frame assembly 91 drives the adsorption assembly 92 to move downward to adsorb and fix the pre-pressed fiber material. Then, the servo moving assembly 32 moves the adsorption assembly 92 above the second forming die 16, and the first compression assembly 14 pushes the first forming die 15 to move downward, and the fiber product is formed by the first forming die 15 and the second forming die 16;

[0040] During the process of the servo motor 42 driving the first lead screw 43 to rotate and the inner box moving upward, the first lead screw 43 will drive the first synchronous pulley 101 to rotate. At this time, the synchronous belt 102 drives the second synchronous pulley 103 to rotate. At the same time, the first connecting shaft 104, the first bevel gear 105 and the second bevel gear 106 will drive the second lead screw 107 to rotate, and then the second lead screw 107 drives the second lead screw block 109 to slide along the third mounting frame 108. The movement of the second lead screw block 109 will drive the mixing frame 111 to move in the inner box. During the movement of the mixing frame 111, while the vacuum pump 72 discharges the air inside the pre-pressing feeding die 62 through the first connecting pipe 73 to generate suction, the air will be injected into the waste liquid storage tank 71 through the second connecting pipe 74, increasing the air pressure inside the waste liquid storage tank 71. The high-pressure air passes through the fourth connecting pipe 110 and the mixing frame 111 into the inner box to mix the fiber slurry in the inner box, improving the uniformity of the fibers in the slurry;

[0041] When driving the first lead screw 43 by the servo motor 42 to drive the inner box to lift, the second lead screw 107 is linked through the synchronous belt 102, so that the mixing rack 111 moves in the inner box; at the same time, the high-pressure air generated by the vacuum pump 72 is introduced into the mixing rack 111 through the fourth connecting pipe 110 to realize the dynamic mixing of the fiber slurry, improve the fiber uniformity, complete the integration of slurry mixing and adsorption. The moving mechanism 3 cooperates with the lifting mechanism 4 to accurately dock the inner box with the pre-pressing and feeding die 62; after the flipping assembly 61 completes the die flipping, the second compression assembly 81 drives the pre-pressing die 82 to perform pre-pressing; the adsorption assembly 92 is coordinated by the servo moving assembly 32 and the lifting frame assembly 91 to transfer the pre-pressed material to the first forming die 15 and the second forming die 16 to complete the final forming, forming an "adsorption - pre-pressing - forming" production line.

[0042] Example 2: According to Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, a laser thickness gauge 112 is fixedly connected to the upper part of the mixing rack 111. The laser thickness gauge 112 is located above the pre-pressing and feeding die 62, and the laser thickness gauge 112 is used to detect the thickness of the fiber slurry attached to the surface of the pre-pressing and feeding die 62. A booster pump 75 is installed on the side of the waste liquid storage tank 71. The end of the booster pump 75 is fixedly connected to a third connecting pipe 76. The third connecting pipe 76 is fixedly connected to the waste liquid storage tank 71. A fiber slurry filtering component is arranged inside the waste liquid storage tank 71, and a drain pipe is fixedly connected to the bottom of the waste liquid storage tank 71. A valve is installed on the surface of the drain pipe. A pre-pressing module mechanism 6 is arranged inside the slurry tank assembly 5. A pre-pressing mechanism 8 and a feeding mechanism 9 are respectively installed on the upper part of the moving mechanism 3. The feeding mechanism 9 is located on one side of the pre-pressing mechanism 8. The moving mechanism 3 includes a second fixing frame 31. A servo moving component 32 is fixedly connected to the upper part of the second fixing frame 31. The servo moving component 32 is used to drive the pre-pressing mechanism 8 and the feeding mechanism 9 to move synchronously. The pre-pressing mechanism 8 includes a second compression component 81. The bottom of the second compression component 81 is fixedly connected to a pre-pressing die 82. A second industrial camera 83 is installed on the side of the pre-pressing die 82, and a pressure sensor is installed at the bottom of the pre-pressing die 82. The feeding mechanism 9 includes a lifting frame component 91. An angle adjusting component 93 is fixedly connected to the surface of the lifting frame component 91, and an adsorption component 92 is rotatably connected to the lower part of the lifting frame component 91. The angle adjusting component 93 is used to adjust the horizontal angle of the adsorption component 92. The adsorption component 92 is used to adsorb and feed the pre-pressed fiber product.

[0043] In this embodiment, after the pre-pressing and loading die 62 finishes loading and is flipped by the flipping assembly 61, the lifting mechanism 4 drives the inner box to move downward. At this time, the second lead screw 107 drives the second lead screw block 109 to slide, resetting the mixing rack 111. At this time, the mixing rack 111 drives the laser thickness gauge 112 to scan the fiber slurry on the surface of the pre-pressing and loading die 62 to detect its thickness. After the detection meets the pre-pressing standard, the pre-pressing mechanism 8 performs a pre-pressing operation on the fiber slurry inside the pre-pressing and loading die 62;

[0044] Before the pre-pressing mechanism 8 performs the pre-pressing operation, the position of the pre-pressing mechanism 8 is adjusted by the servo moving assembly 32. The position information of the pre-pressing and loading die 62 is collected by the second industrial camera 83. Whether the position between the pre-pressing and forming die 82 and the pre-pressing and loading die 62 is accurate is calculated by an external control system. After the pre-pressing and forming die 82 moves to the set position above the pre-pressing and loading die 62, the second compression assembly 81 pushes the pre-pressing and forming die 82 downward to perform the pre-pressing operation, and the pressure during pre-pressing is monitored by the pressure sensor installed on the surface of the pre-pressing and forming die 82;

[0045] After pre-pressing is completed, when the feeding mechanism 9 is loading, when the angle adjustment assembly 93 moves the pre-pressed fiber material above the second forming die 16, the placement angle and position information of the fiber material adsorbed by the lower part of the adsorption assembly 92 are collected by the first industrial camera 2. The placement angle and position information of the fiber material are judged by an external control system. The position of the fiber collection is adjusted by moving the servo moving assembly 32. The angle adjustment assembly 93 drives the adsorption assembly 92 to rotate to adjust the angle of the fiber material. At the same time, the rotation angle of the first mounting frame 12 is adjusted by the cam divider 13, and the rotation angle of the first mounting frame 12 is monitored by the encoder 17 to ensure the accurate position of the second forming die 16 after rotation, so that the lifting frame assembly 91 can accurately place the fiber material into the second forming die 16;

[0046] The thickness of the fiber slurry adsorbed on the surface of the pre-pressing and loading die 62 is detected by the laser thickness gauge 112. When the thickness is too thick, the adsorption operation time of the fiber slurry on the surface of the pre-pressing and loading die 62 is reduced by the vacuum pump 72, and vice versa, the adsorption operation time is increased.

[0047] When using the lifting mechanism 4 to drive the inner box to reset, the linkage second lead screw 107 and the second lead block 109 drive the mixing rack 111, so that the mounted laser thickness gauge 112 scans the surface fiber slurry of the pre-pressing and feeding die 62 to detect the thickness in real time; when the detected value exceeds the standard, the adsorption duration of the vacuum pump 72 is dynamically adjusted to accurately control the slurry adsorption amount, ensuring that the thickness tolerance is maintained within the standard. In the pre-pressing link, the servo moving component 32 cooperates with the second industrial camera 83 to collect the position information of the pre-pressing and feeding die 62. After being calculated by the control system, the second compression component 81 drives the pre-pressing and forming die 82 to press down, and the pressure sensor monitors the pre-pressing pressure in real time to ensure uniform pre-pressing density. In the feeding and forming stage, the first industrial camera 2 cooperates with the angle adjustment component 93 and the servo moving component 32 to calibrate the position and angle of the fiber material adsorbed by the adsorption component 92; at the same time, the cam divider 13 combines with the encoder 17 to accurately control the rotation of the first mounting frame 12, ensuring accurate positioning of the second forming die 16 and realizing high-precision alignment of the fiber material and the die.

[0048] Embodiment 3: Figure 1 、 Figure 2 and Figure 3 As shown in, the forming mechanism 1 includes a first fixed frame 11. The bottom of the first fixed frame 11 is fixedly connected with a cam divider 13, and the upper part of the first fixed frame 11 is rotatably connected with a first mounting frame 12. Multiple groups of first compression components 14 are installed on the top of the first mounting frame 12. The bottom of the first compression component 14 is installed with a first forming die 15. A plurality of second forming dies 16 are installed on the surface of the first mounting frame 12. The second forming die 16 is located below the first forming die 15. A first industrial camera 2 is arranged on the side of the second forming die 16. The first industrial camera 2 is installed on the surface of the first mounting frame 12. The cam divider 13 is used to drive the first mounting frame 12 to rotate. An encoder 17 is installed on the upper part of the first mounting frame 12. The encoder 17 is used to monitor the rotation angle of the first mounting frame 12.

[0049] In this embodiment, during the entire process of forming and processing the fiber material, the pre-pressing and feeding die 62 is driven to flip by the flipping assembly 61. During the process of pre-pressing and forming the fiber slurry on the surface of one pre-pressing and feeding die 62 by the moving mechanism 3, the other pre-pressing and feeding die 62 simultaneously performs the slurry adsorption operation under the action of the cloth feeding mechanism 7. During the process of feeding the pre-pressed and formed material inside one pre-pressing and feeding die 62 by the feeding mechanism 9, the flipping assembly 61 drives the other pre-pressing and feeding die 62 that has completed the slurry feeding to flip, saving the time for slurry feeding. At the same time, after the feeding mechanism 9 feeds the pre-pressed and formed material to the upper part of a second forming die 16 on the surface of the first mounting frame 12, the first mounting frame 12 is driven to rotate by the cam divider 13, and the other second forming die 16 is moved to the end of the feeding mechanism 9 to prepare for the final pressing operation of the pre-pressed and formed material again, improving the overall processing efficiency;

[0050] While generating suction force on the pre-pressing and feeding die 62 by the vacuum pump 72, some fibers will be sucked into the waste liquid storage tank 71 through the first connecting pipe 73 by the pre-pressing and feeding die 62. The fiber slurry filtering assembly inside the waste liquid storage tank 71 filters the fiber slurry to avoid material loss caused by the discharge of fibers with the sucked liquid. When the pressure provided by the vacuum pump 72 inside the waste liquid storage tank 71 is insufficient, the pressure is supplemented to the waste liquid storage tank 71 by the booster pump 75 to ensure that there is sufficient gas in the mixing rack 111 to mix the fiber slurry. At the same time, by supplementing the pressure inside the waste liquid storage tank 71, there is a pressure difference between the upper and lower parts of the fiber slurry filtering assembly, enabling the fiber slurry filtering assembly to quickly filter the fibers;

[0051] The synchronous operation of the double pre-pressing feeding mold 62 is realized by the flip assembly 61. When the moving mechanism 3 performs pre-pressing molding on one of them, the other mold completes the slurry adsorption synchronously through the cloth mechanism 7. With the linkage of the feeding mechanism 9 and the cam divider 13, the second molding mold 16 on the No. 1 mounting frame 12 is rotated to the final pressing process, forming an "adsorption-pre-pressing-molding" assembly line operation to improve efficiency. At the same time, the fiber waste liquid generated during the adsorption process of the vacuum pump 72 is introduced into the waste liquid storage box 71 through the No. 1 connecting pipe 73, and is separated and recovered through the internal filtering assembly to avoid material loss; when the pressure of the vacuum pump 72 is insufficient, the booster pump 75 automatically supplements the pressure to ensure that the mixing frame 111 obtains sufficient air pressure to maintain the uniformity of slurry mixing, and at the same time, the pressure difference is used to accelerate the filtration of the waste liquid to realize the closed loop of "production-recycling-reuse". Through the parallel station design and the waste liquid circulation system, this solution reduces material costs and environmental pollution while improving production capacity, and is suitable for large-scale fiber product production. The automated multi-station fiber forming equipment significantly improves production efficiency and material utilization through parallel operation and resource recycling mechanism: the flip assembly 61 is used to cooperate with the moving mechanism 3 to realize the "pre-pressing-adsorption" synchronous operation of the two pre-pressing feeding molds 62. When one mold is pre-pressing, the other is synchronously adsorbing the slurry, shortening the single batch processing time; the feeding mechanism 9 is linked with the cam divider 13. After completing the loading of a No. 2 forming mold 16, it immediately switches to the next station by rotating the No. 1 mounting frame 12 to reduce waiting time. In terms of resource recycling, when the suction force generated by the vacuum pump 72 absorbs the slurry through the No. 1 connecting pipe 73, the filter component in the waste liquid storage box 71 intercepts the fiber. When the vacuum pressure is insufficient, the booster pump 75 supplements the pressure, which not only ensures that the mixing frame 111 fully mixes the slurry, but also accelerates the separation efficiency of the filter component through the pressure difference. The scheme improves processing efficiency, reduces material loss, and improves comprehensive energy efficiency through the "multi-station parallel + material recovery" mode, and is suitable for continuous and large-scale production of high-precision fiber products.

[0052] Working principle and usage method of this device: An external fiber slurry feeding device injects fiber slurry into the inner box of the slurry tank assembly 5. Subsequently, the servo motor 42 drives the first lead screw 43 to rotate, driving the first lead block 44 and the connecting frame 45 to move upward. At this time, the second mounting frame 46 will push the inner box upward, causing the fiber slurry in the inner box to come into contact with the surface of the pre-pressing and feeding die 62. During the process of the pre-pressing and feeding die 62 coming into contact with the fiber slurry, start the vacuum pump 72 to generate suction on the contact surface between the pre-pressing and feeding die 62 and the fiber slurry through the first connecting pipe 73, adsorbing the fibers in the fiber slurry onto the surface of the pre-pressing and feeding die 62. Subsequently, drive the pre-pressing and feeding die 62 to flip through the flipping assembly 61, and the lifting mechanism 4 drives the inner box to move downward. After the pre-pressing and feeding die 62 with the fiber material flips, the second compression assembly 81 pushes the pre-pressing and forming die 82 to pre-press and form the fiber material inside the pre-pressing and feeding die 62. After pre-pressing and forming, the second compression assembly 81 drives the pre-pressing and forming die 82 to move upward. At the same time, the servo moving assembly 32 moves the adsorption assembly 92 above the pre-pressing and feeding die 62, and drives the adsorption assembly 92 to move downward through the lifting frame assembly 91 to adsorb and fix the pre-pressed fiber material. Then, the servo moving assembly 32 moves the adsorption assembly 92 to the upper part of the second forming die 16, and the first compression assembly 14 pushes the first forming die 15 to move downward, and the fiber product is formed through the first forming die 15 and the second forming die 16.
