Description

Technical Field

[0001] This application relates to the field of carbon paper processing equipment technology, and in particular to a carbon paper impregnation device. Background Technology

[0002] The wet forming technology for carbon paper mainly includes processes such as carbon fiber dispersion, carbon paper precursor fabrication, resin impregnation, resin curing, carbonization, and graphitization. In the resin impregnation process for carbon paper preparation, in order to control the porosity of the carbon paper while taking into account its density and structural stability, and to ensure that the resin can penetrate evenly into the interior of the carbon paper, thereby improving the mechanical strength and uniformity of the carbon paper, using appropriate impregnation equipment is a necessary condition for controlling various properties of the carbon paper.

[0003] In related technologies, manual impregnation is often used. Personnel move the carbon paper to be impregnated into the impregnation tank, then inject the impregnation solution into the tank. Personnel observe and stop injecting the solution when it reaches the appropriate position. The operator then manually places the carbon paper into the impregnation solution and performs a series of operations to complete the impregnation process. After impregnation is complete, the impregnated carbon paper is removed and proceeded to the next process.

[0004] Regarding the aforementioned technologies, manual impregnation of carbon paper is possible, but manual impregnation involves manually holding the carbon paper into the solvent tank, which increases the workload and results in low impregnation efficiency. Utility Model Content

[0005] To overcome the above problems, this application provides a carbon paper impregnation apparatus.

[0006] The carbon paper impregnation equipment provided in this application adopts the following technical solution:

[0007] A carbon paper impregnation device includes an impregnation assembly, a conveying assembly, a placement assembly, and a rotating assembly. The impregnation assembly includes an impregnation tank, and the conveying assembly is located near one side of the impregnation tank. The conveying assembly is used to convey the impregnated carbon paper.

[0008] The placement assembly includes a placement frame and a placement component. The placement frame is located within the impregnation tank, and its central axis along its depth direction coincides with the central axis of the impregnation tank. The placement component includes two screens, both of which are located within the placement frame and are distributed along the depth direction of the placement frame. A sandwich for placing carbon paper is formed between the two screens. The screen near the bottom of the placement frame is connected to the placement frame, and the side of the screen near the top of the placement frame is hinged to the placement frame. The side of the screen away from the hinge end is detachably connected to the placement frame.

[0009] The rotating assembly includes a lifting member connected to the impregnation tank. The lifting member is connected to the placement frame to drive the placement frame to move closer to or further away from the interior of the impregnation tank. When the placement frame is located inside the impregnation tank, a gap is left between the side wall of the placement frame and the inner wall of the impregnation tank.

[0010] By adopting the above technical solution, when carbon paper needs to be impregnated, the operator pulls the screen near the top of the placement frame to separate one end of the screen from the placement frame. Then, the operator places the carbon paper in the interlayer and fixes the screen near the top of the placement frame to the placement frame. The lifting component then drives the placement frame to move closer to the impregnation tank to achieve carbon paper impregnation. The conveying component can transport the impregnated carbon paper, improving conveying efficiency. The placement frame can be located in the impregnation tank and its central axis can coincide with the impregnation tank, facilitating carbon paper impregnation. The interlayer formed by the two screens can hold the carbon paper, and the screen connection method makes it convenient to place and remove the carbon paper. The lifting component drives the placement frame to move and achieve carbon paper impregnation, realizing automatic carbon paper impregnation, reducing manual labor, and improving the efficiency and quality of carbon paper impregnation.

[0011] In one specific implementation, the rotating assembly further includes a positioning element and a rotating element. The positioning element includes a rotating rod and a positioning rod, both of which are close to the inner wall of the impregnation tank near the conveying assembly. The rotating rod and the positioning rod are distributed along the conveying direction of the conveying assembly. Both the rotating rod and the positioning rod are perpendicular to the bottom wall of the impregnation tank. A gap is left between the rotating rod and the positioning rod for the placement frame to rotate through. One end of the rotating rod is rotatably connected to the bottom wall of the impregnation tank, and one end of the positioning rod is connected to the bottom wall of the impregnation tank. The top of the positioning rod is connected to the inner wall of the impregnation tank. The top of the impregnation tank is flush with the inner wall of the impregnation tank. The rotating rod and the positioning rod are both left with gaps. The placement frame is connected to two collars on one side. The two collars are located on the other two opposite side walls of the placement frame. One collar is fitted around the rotating rod, and the other collar is for the positioning rod to pass through and fit. When carbon paper needs to be placed between the two screens, the placement frame is located above the conveying assembly. The rotating rod rotates 90° so that the positioning rod fits with the collar. The central axis of the placement frame along its depth direction can coincide with the central axis of the impregnation tank.

[0012] The rotating component is connected to the immersion tank. The rotating component is connected to the rotating rod to drive the rotating rod to rotate 90° forward and backward. The lifting component is connected to the top of the rotating rod. A sliding groove is formed on the peripheral wall of the rotating rod along its length. A slider located in the sliding groove is connected to the inner side of the collar on the rotating rod. The slider can slide back and forth along the sliding groove.

[0013] By adopting the above technical solution, the rotating rod of the positioning component, in conjunction with the collar and matching groove of the placement frame, allows the central axis of the placement frame to coincide with the central axis of the impregnation tank after the rotating rod rotates 90°. This facilitates the accurate placement of carbon paper in the appropriate position within the impregnation tank for impregnation. The rotating component drives the rotating rod to rotate 90° in both directions, enabling the placement frame to switch positions above the conveying assembly and within the impregnation tank, thus facilitating the placement and impregnation of carbon paper. The sliding groove of the rotating rod, in conjunction with the inner slider of the collar, allows the placement frame to move stably towards or away from the impregnation tank under the drive of the lifting component, ensuring the smoothness and accuracy of the placement frame's movement. Overall, this improves the convenience and accuracy of the carbon paper impregnation equipment operation, enhancing the efficiency and quality of carbon paper impregnation.

[0014] In one specific implementation, the impregnation assembly further includes a support member comprising two support rods, each close to one of the two sidewalls opposite the impregnation tank. The support rods are arranged in a direction parallel to the bottom wall of the impregnation tank, and both ends of the support rods are connected to the impregnation tank. The two support rods can support the placement frame, and a gap is left between the support rods and the bottom wall of the impregnation tank.

[0015] By adopting the above technical solution, the two support rods can support the placement frame, so that the placement frame is placed in the impregnation solution without contacting the bottom of the impregnation tank, thus avoiding contamination or damage to the carbon paper. In addition, the support rods leave a gap with the bottom wall of the impregnation tank, ensuring the stability of the placement frame when it is placed.

[0016] In one specific implementation, the conveying assembly includes a conveyor frame and a conveyor component. The conveyor frame is located near the impregnation tank. The conveyor component includes two rollers, a conveyor belt, and a drive motor. The two rollers are distributed along the direction of the rotating rod and the positioning rod. The rollers are arranged perpendicular to the conveyor frame and near the side wall of the impregnation tank. Both ends of the rollers are rotatably connected to the conveyor frame. The conveyor belt is wound around the two rollers. The drive motor is located near one of the rollers. The housing of the drive motor is connected to the conveyor frame. The output shaft of the drive motor is coaxially fixed with the roller.

[0017] By adopting the above technical solution, the impregnated carbon paper is placed on a conveyor belt, and the drive motor drives the roller shaft to rotate and move the conveyor belt, which can receive the impregnated carbon paper and quickly transfer it to the next process.

[0018] In one specific implementation, the conveyor belt surface is provided with a plurality of through-holes, the plurality of holes being distributed along an array, and the diameter of the holes being smaller than the minimum particle size of the suspended particles in the impregnation solution.

[0019] By adopting the above technical solution, excess impregnation liquid can be easily drained from the carbon paper after impregnation, while particles can be effectively intercepted from flowing out through the channels, thereby ensuring the quality of the impregnated carbon paper.

[0020] In one specific implementation, the system further includes at least one stirring assembly, which includes a stirring element and a power element. The stirring element includes a stirring rod and a stirring paddle. The stirring rod is perpendicular to the side wall of the impregnation tank and passes through the side wall of the impregnation tank. The stirring paddle is located inside the impregnation tank and is coaxially fixed with the stirring rod. The stirring rod is rotatably connected to the side wall of the impregnation tank. The stirring paddle is capable of stirring the impregnation solution. The power element is connected to the impregnation tank and is used to drive the stirring rod to rotate.

[0021] The plane containing the two support rods is located above the two agitators, and the placement frame will not interfere with the agitators during their rotation.

[0022] By adopting the above technical solution, the rotation of the agitator causes the resin solution or hydrophobic agent in the impregnation tank to flow dynamically, avoiding solution sedimentation. At the same time, the flowing liquid can more easily enter the product, improving the uniformity of the impregnated product. Furthermore, the placement frame will not interfere with the rotation of the agitator, allowing the agitator assembly to operate normally and ensuring the agitation effect.

[0023] In one specific implementation, two stirring assemblies are provided, each located on one of the opposite side walls of the impregnation tank.

[0024] By adopting the above technical solution, the two stirring components located on opposite sides of the impregnation tank can make the resin solution or hydrophobic agent in the impregnation tank flow dynamically, avoid solution sedimentation, make the flowing liquid easier to enter the product, and improve the uniformity of the impregnated product.

[0025] In one specific implementation, a locking block is connected to the side of the screen near the top of the placement frame away from the hinge end, and a locking groove corresponding to the locking block is opened on the placement frame, with the locking block and the locking groove being interference fit.

[0026] By adopting the above technical solution, when placing the carbon paper in the interlayer between the two screens, pulling the locking block separates the locking block from the slot, which opens the screen near the top of the placement frame; after the carbon paper is placed, the screen is fixed by the interference fit between the locking block and the slot, which facilitates the placement and fixation of the carbon paper and improves the ease of operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The designed carbon paper impregnation equipment features a conveying component that transports the impregnated carbon paper, improving conveying efficiency; a placement frame that can be located within the impregnation tank with its central axis coinciding with the tank, facilitating carbon paper impregnation; a sandwich formed by two screens that can hold the carbon paper, with the screen connection method making placement and removal convenient; and a lifting component that drives the placement frame to achieve automatic carbon paper impregnation, reducing manual labor and improving impregnation efficiency and quality.

[0029] 2. The designed carbon paper impregnation equipment features a rotating component that drives a rotating rod to rotate 90° in both directions, enabling the placement frame to switch positions above the conveying assembly and within the impregnation tank. This facilitates the placement and impregnation of the carbon paper. The sliding groove of the rotating rod engages with the inner slider of the collar, allowing the placement frame to move stably towards or away from the impregnation tank under the drive of the lifting component. This ensures the smoothness and accuracy of the placement frame's movement, thereby improving the overall convenience and accuracy of the carbon paper impregnation equipment and enhancing the efficiency and quality of carbon paper impregnation.

[0030] 3. The designed carbon paper impregnation equipment has two stirring components located on opposite sides of the impregnation tank, which enable the resin solution or hydrophobic agent in the impregnation tank to flow dynamically, preventing solution sedimentation and making it easier for the flowing liquid to enter the product, thereby improving the uniformity of the impregnated product.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a carbon paper impregnation device.

[0039] Reference Figure 1 A carbon paper impregnation device includes an impregnation component 1, at least one stirring component 2, a conveying component 3, a placing component 4, and a rotating component 5. The stirring component 2 is connected to the impregnation component 1, the conveying component 3 is close to the impregnation component 1, the placing component 4 is connected to the rotating component 5, and the rotating component 5 is connected to the impregnation component 1.

[0040] Reference Figure 1 and Figure 2The impregnation assembly 1 includes an impregnation tank 11 and a support member 12. In this embodiment, the impregnation tank 11 is a rectangular tank, and an inlet / outlet 111 is provided on the side wall of the impregnation tank 11. The inlet / outlet 111 is close to the bottom wall of the impregnation tank 11 and can be used for the entry and exit of the impregnation solution, which improves the convenience of operation. The material of the impregnation tank 11 can be a corrosion-resistant metal material, such as stainless steel, to ensure that it will not be corroded when in contact with the impregnation solution for a long time. The support member 12 includes two support rods 121 symmetrically arranged on the bottom edge of the impregnation tank 11. Each of the two support rods 121 is close to the two side walls of the impregnation tank 11 directly opposite each other. The support rod 121 is arranged parallel to the bottom wall of the impregnation tank 11. Both ends of the support rod 121 are welded to the impregnation tank 11. The support rod 121 can be a cylindrical rod, and its material can be metal, such as stainless steel, to provide sufficient support force, or it can be a rigid plastic rod. The function of the support rod 121 is to support the carbon paper, so that the carbon paper is placed in the impregnation solution without contacting the bottom of the impregnation tank 11, thus avoiding contamination or damage to the carbon paper. A handle 112 is provided on each of the two sides of the outer wall of the impregnation tank 11, and the handle 112 is welded to the impregnation tank 11 to facilitate the movement of the impregnation tank 11 by personnel.

[0041] Reference Figure 1 and Figure 2 In this embodiment, two stirring components 2 are provided, each located on one of the two opposite side walls of the impregnation tank 11. Each stirring component 2 includes a stirring element 21 and a power element 22. The stirring element 21 includes a stirring rod 211 and a stirring paddle 212. The stirring rod 211 is perpendicular to the side wall of the impregnation tank 11 and passes through the side wall. The stirring paddle 212 is located inside the impregnation tank 11 and is coaxially welded to the stirring rod 211. The stirring rod 211 is rotatably connected to the side wall of the impregnation tank 11. The two stirring paddles 212 can rotate in the same direction and alternately. The cyclic and reverse rotations allow the resin solution or hydrophobic agent in the impregnation tank 11 to flow dynamically, preventing solution sedimentation. On the other hand, the flowing liquid is more likely to enter the product, improving the uniformity of the impregnated product. The plane of the two support rods 121 is located above the two stirring paddles 212. The power component 22 corresponds one-to-one with the stirring rod 211. In this embodiment, the power component 22 is a motor. The motor housing is fixedly connected to the outer wall of the impregnation tank 11 by screws. The output shaft of the motor is coaxially fixedly connected to the stirring rod 211 by a coupling. The motor drives the stirring rod 211 to rotate.

[0042] Reference Figure 1 and Figure 2The conveying assembly 3 includes a conveying frame 31 and a conveying component 32. The conveying frame 31 is located near one side wall of the impregnation tank 11. The conveying component 32 includes two rollers 321, a conveyor belt 322, and a drive motor 323. The two rollers 321 are distributed parallel to the conveying frame 31 near the side wall of the impregnation tank 11, and are also arranged perpendicular to the conveying frame 31 near the side wall of the impregnation tank 11. Both ends of the rollers 321 are rotatably connected to the conveying frame 31. The conveyor belt 322 is wound around the two rollers 321. The top of the conveyor belt 322 is slightly higher than the top of the impregnation tank 11. The surface of the conveyor belt 322 is provided with multiple through guide holes 32. 21. Multiple guide holes 3221 are distributed along the array to facilitate the outflow of excess impregnation liquid after impregnation. The diameter of the guide holes 3221 is smaller than the minimum particle size of suspended particles in the impregnation solution, which can effectively intercept particles from flowing out through the channels. The function of the conveyor belt 322 is to receive the impregnated product and quickly transfer it to the next process. The drive motor 323 is close to one of the rollers 321. The housing of the drive motor 323 is fixedly connected to the conveyor frame 31 by screws. The output shaft of the drive motor 323 is coaxially fixedly connected to the roller 321 by a coupling. The drive motor 323 drives the roller 321 to rotate, thereby driving the conveyor belt 322 to move.

[0043] Reference Figure 2 and Figure 3The placement component 4 includes a placement frame 41 and a placement element 42. The placement frame 41 has a placement groove 411 at its top. The placement element 42 includes two screens 421, both located within the placement groove 411. The two screens 421 are distributed along the depth direction of the placement frame 41, forming a sandwich layer for placing carbon paper. The screen 421 near the bottom of the placement frame 41 is fixedly connected to the placement frame 41 by screws. One side of the screen 421 near the top of the placement frame 41 is hinged to the placement frame 41, and the other side is fixedly connected to a locking block 4211 by screws. The placement frame 41 has a locking groove 412 corresponding to the locking block 4211, and the locking block 4211 and the locking groove 412 are press-fitted. The surface of the screen 421 has a mesh structure with a reasonable aperture, which facilitates carbon paper impregnation and allows the impregnation solution to better penetrate the carbon paper. 21. Metal or plastic wire mesh can be used. When carbon paper needs to be placed, the operator pulls the locking block 4211 to separate the locking block 4211 from the slot 412. Then, the operator places the carbon paper in the interlayer and fixes the screen 421 near the top of the placement frame 41 to the placement frame 41. Resin impregnation can then be performed. When the placement frame 41 is in the impregnation tank 11, the two support rods 121 contact the bottom of the placement frame 41 to support the placement frame 41. There is a gap between the side wall of the placement frame 41 and the inner wall of the impregnation tank 11. During the rotation of the two stirring paddles 212, the placement frame 41 will not interfere with the stirring paddles 212. After impregnation, the placement frame 41 is rotated onto the conveyor belt 322. The operator pulls the locking block 4211 to separate the locking block 4211 from the slot 412. The operator then takes out the impregnated carbon paper and places it on the conveyor belt 322.

[0044] Reference Figure 2 , Figure 4 and Figure 5The rotating assembly 5 includes a positioning component 51, a rotating component 52, and a lifting component 53. The positioning component 51 includes a rotating rod 511 and a positioning rod 512. Both the rotating rod 511 and the positioning rod 512 are close to the side wall of the impregnation tank 11 near the conveyor belt 322. Both the rotating rod 511 and the positioning rod 512 are located inside the impregnation tank 11 and are distributed along the conveying direction of the conveyor belt 322. Both the rotating rod 511 and the positioning rod 512 are perpendicular to the side wall of the impregnation tank 11. The bottom wall is vertically set, and a gap is left between the rotating rod 511 and the positioning rod 512 for the placement frame 41 to rotate through. One end of the rotating rod 511 is rotatably connected to the bottom wall of the impregnation tank 11, and one end of the positioning rod 512 is welded to the bottom wall of the impregnation tank 11. The top of the positioning rod 512 is flush with the top of the impregnation tank 11. A gap is left between the rotating rod 511 and the positioning rod 512 and the inner wall of the impregnation tank 11. Two collars 413 are welded to one side of the placement frame 41. Each of the 413 is located on one of the two opposite sides of the placement frame 41. One of the collars 413 is fitted onto the circumferential wall of the rotating rod 511, and the other collar 413 is fitted onto and passes through the positioning rod 512. When the carbon paper is placed between the two screens 421, the rotating rod 511 rotates 90°, allowing the positioning rod 512 to pass through the corresponding collar 413. At this time, the central axis of the placement frame 41 coincides with the central axis of the impregnation tank 11. The circumferential wall of the rotating rod 511 has a sliding groove 5111, which is set along the length of the rotating rod 511. A slider 4131 is provided inside the collar 413 on the rotating rod 511. The slider 4131 is located in the sliding groove 5111 and can slide back and forth along the sliding groove 5111. At this time, the collar 413 in contact with the positioning rod 512 slides along the length of the positioning rod 512 until the bottom of the placement frame 41 contacts the support rod 121, so that the carbon paper is impregnated with resin.

[0045] Reference Figure 2 , Figure 4 and Figure 5The rotating component 52 includes a fixed base 521 and a rotating motor 522. The fixed base 521 is fixedly connected to the outer wall of the impregnation tank 11 by screws, and the fixed base 521 is close to the rotating rod 511. The housing of the rotating motor 522 is fixedly connected to the fixed base 521 by screws. The output shaft of the rotating motor 522 is coaxially fixedly connected to the rotating rod 511 by a coupling. The rotating motor 522 drives the rotating rod 511 to rotate 90° forward and backward. The lifting component 53 includes a fixed plate 531 and a lifting cylinder 532. The fixed rod is fixedly connected to the end of the rotating rod 511 away from the bottom wall of the impregnation tank 11 by screws. The setting direction of the lifting cylinder 532 is parallel to the length direction of the rotating rod 511. The cylinder body of the lifting cylinder 532 is fixedly connected to the fixed plate 531 by screws. The piston rod of the lifting cylinder 532 is connected to the top of the placement frame 41 by screws. With the wire fixed connection, when the rotating motor 522 drives the rotating rod 511 to rotate 90°, the central axis of the placement frame 41 coincides with the central axis of the impregnation tank 11. Then, the lifting cylinder 532 is activated, and the lifting cylinder 532 pushes the placement frame 41 towards the inside of the impregnation tank 11 until the bottom of the placement frame 41 contacts the support rod 121, thus impregnating the carbon paper. After impregnation, the lifting cylinder 532 is activated again, and the lifting cylinder 532 pulls the placement frame 41 away from the bottom wall of the impregnation tank 11 until the bottom of the placement frame 41 is slightly higher than the top of the impregnation tank 11. Then, the rotating motor 522 is activated, and the rotating motor 522 drives the rotating rod 511 to rotate 90° in the opposite direction, so that the placement frame 41 is above the conveyor belt 322. The personnel can then take out the carbon paper and place it on the conveyor belt 322 to continue the impregnation of the next carbon paper.

[0046] The implementation principle of the carbon paper impregnation equipment in this application embodiment is as follows: When carbon paper needs to be impregnated, firstly, the operator moves the impregnation tank 11 close to the conveyor assembly 3, so that the top of the impregnation tank 11 is flush with the top of the conveyor belt 322. Then, the impregnation solution is injected into the impregnation tank 11 through the inlet / outlet 111. After the injection is completed, the solution in the impregnation tank 11 is stirred by the stirring assembly 2. Then, the carbon paper is placed in the placement assembly 4, and the rotating assembly 5 is started. The rotating part 52 and the lifting part 53 in the rotating assembly 5 cooperate to insert the placement assembly 4 containing the carbon paper into the impregnation solution for impregnation. After impregnation is completed, the placement assembly 4 is moved above the conveyor belt 322, and the operator takes out the carbon paper and places it on the conveyor belt 322. After that, the remaining carbon paper can be impregnated. The entire equipment has a reasonable structural design and is easy to operate. It effectively solves the problems existing in the carbon paper impregnation process in the prior art and improves the production quality and efficiency of carbon paper.

[0047] When carbon paper needs to be placed in the placement assembly 4, the operator activates the rotating component 52, which drives the rotating rod 511 to rotate, positioning the placement frame 41 above the conveyor belt 322. The operator then pulls the locking block 4211 to separate it from the locking slot 412. The operator then places the carbon paper in the interlayer and secures the screen 421 near the top of the placement frame 41 to the frame. Subsequently, when the rotating motor 522 drives the rotating rod 511 to rotate 90°, the central axis of the placement frame 41 coincides with the central axis of the impregnation tank 11, and the lifting cylinder 532 pushes... The placement frame 41 moves into the impregnation tank 11 until the bottom of the placement frame 41 contacts the support rod 121, thus impregnating the carbon paper. After impregnation, the lifting cylinder 532 is activated again, pulling the placement frame 41 away from the bottom wall of the impregnation tank 11 until the bottom of the placement frame 41 is slightly higher than the top of the impregnation tank 11. Then, the rotating motor 522 is activated, driving the rotating rod 511 to rotate 90° in the opposite direction, so that the placement frame 41 is positioned above the conveyor belt 322. Personnel can then remove the carbon paper and place it on the conveyor belt 322.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
