Description

Technical Field

[0001] The present invention relates to the technical field of carbon felt production, and particularly relates to a production and forming device and process for carbon fiber thermal insulation felt. Background Art

[0002] Carbon fiber surface felt is a non-woven carbon fiber felt made by cutting carbon fiber short filaments, evacuating and dispersing them, and using a wet forming method. It has the characteristics of uniform fiber distribution, flat surface, high air permeability, and strong adsorption. It is applied in various fields and composite materials. It can give full play to the excellent performance of carbon fiber materials and effectively reduce costs. It is a new type of high-performance material.

[0003] The patent document with the patent number CN112503947A discloses an equipment for producing carbon fiber carbon felt, which consists of two furnace bodies, a foaming furnace and a carbonization furnace. The foaming furnace is connected to the carbonization furnace through a sealed first atmosphere buffer box to prevent external air from entering. The foaming furnace is used to prepare a high-porosity carbon fiber carbon felt precursor through a foaming process. The foaming furnace mainly consists of a screw conveying mechanism, a heating device and a gas introduction device; the carbonization furnace is used to heat-treat the carbon fiber carbon felt precursor to obtain the final product. The carbonization furnace mainly consists of a heating device and a traction device.

[0004] However, in the actual use process, during the production of carbon felt, the carbon felt needs to be impregnated with resin first.

Preferably, the gluing member includes an upper gluing roller arranged behind the cutting member and controlled to move by an electric cylinder, a supporting roller arranged obliquely below the rear side of the upper gluing roller, and a lifting plate for fixing the upper gluing roller and the supporting roller. A lower gluing roller arranged obliquely below the rear side of the supporting roller and controlled to move up and down by a telescopic cylinder, and a slide rail for driving the lower gluing roller to slide horizontally.

[0008] Preferably, the folding assembly includes a pressing member arranged behind the gluing member and two groups of fixing members for respectively fixing the front end and the rear end of the fiber cloth. Each group of fixing members includes a transfer block arranged on both sides of the conveyor belt and controlled to move up and down by an electric cylinder, a pressing rod hinged to the transfer block by a motor, and a plurality of fixing needles arranged on the lower end surface of the pressing rod. The pressing member includes a pressing plate arranged at the rear end of the fiber cloth and provided with a plurality of fixing needles at the lower end, the two ends of the pressing plate are connected to the frame by threads, and the slide rail drives the pressing plate to move up and down through the transmission mode of a gear and a rack. It also includes a needle punching roller arranged behind the pressing plate.

[0009] Preferably, the edge locking assembly is arranged in front of the needle punching machine and includes a positioning member and a edge closing member. The positioning member includes constraint plates arranged on both sides of the conveyor belt, a dial rod arranged at the end of the constraint plate, four groups of fixing plates arranged above the constraint plate, a central frame controlled to slide vertically and connected to the center of the constraint plate by a telescopic cylinder, an extension rod fixedly connected to each group of constraint plates and horizontally slidably connected to the central frame, and a support rod vertically slidably connected to the middle of the central frame.

[0010] Preferably, the edge closing member includes two groups of control frames arranged outside the constraint plates, and four groups of sliding plates are respectively slidably connected to the two groups of control frames by electric cylinders. The upper surface of the sliding plate is a smooth arc and the lower surface is closely attached to the surface of the conveyor belt.

Clamp both sides of the fiber felt with the clamping plates, then the support rod is lifted, making the middle part of the fiber felt bulge and the periphery become lower. By the rotation of the inclined roller, the resin in the middle is squeezed to the periphery. At the same time, the needling plate outside the clamping plates needles the side edges of the fiber felt.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Embodiment 1 As Figure 1 、 Figure 2 shown, a manufacturing and forming device for a carbon fiber thermal insulation felt includes a high-speed web laying machine 0, and further includes: A folding mechanism 1, which is arranged behind the high-speed web laying machine 0 and is used for processing and folding the fiber cloth formed by the high-speed web laying machine 0, including a pretreatment component 11 for cutting and gluing the fiber cloth, and a folding component 12 arranged behind the pretreatment component 11 for folding the fiber cloth; A needling mechanism 2, which is arranged behind the folding component 12 and is used for needling the folded fiber cloth, including a needling machine 21 and a hemming component 22 used in cooperation with the needling machine 21; A supplementary mechanism 3, which is arranged behind the needling mechanism 2 and is used for uniformly coating the adhesive in the needled thermal insulation felt to assist the subsequent curing work of the thermal insulation felt.

[0030] In this embodiment, by setting the folding mechanism 1, the needling mechanism 2 and the supplementary mechanism 3, the forming work of a carbon fiber thermal insulation felt board is completed. The thermal insulation felt board is formed by folding a section of fiber cloth, and at the same time, resin is coated during the folding process, thus saving the subsequent long impregnation process steps for the thermal insulation felt.

[0031] Specifically, for this type of thermal insulation felt, the fiber cloth is formed by the high-speed web laying machine 0, and a section of fiber cloth is stacked back and forth. At the same time, each layer of fiber cloth is coated with a layer of resin during the stacking process. The fiber cloth is cut so that each section of fiber cloth can reserve a certain amount of excess selvage. The selvage is used to hem the four edges of the fiber cloth. On the one hand, it improves the integrity of the fiber felt. On the other hand, it avoids the resin from seeping out from the edges. Then, the needling machine 21 is used to make the fiber felt into a whole. At the same time, the needling machine 21 can also promote the diffusion of the internal resin to a certain extent, so that the resin fills the entire fiber felt. Finally, the side of the hemmed edge is processed so that the fiber cloth on the side also integrates into the whole fiber felt to avoid the dead angle of needling.

[0032] Furthermore, as Figure 3As shown, the preprocessing component 11 includes a punching member 111 for regularly punching the fiber cloth, a cutting member 112 for cutting the fiber cloth, and a gluing member 113 for cooperating with the folding component 12 to apply glue. The punching member 111 includes a punching knife 1111 arranged behind the high-speed web laying machine 0 and controlled to move up and down by an electric cylinder, and an opening cam 1112 arranged below the punching knife 1111 and controlled to rotate by a motor; In this embodiment, by arranging the punching member 111 to punch the fiber cloth, and by arranging the opening cam 1112, when the opening cam 1112 rotates to the upper side, the fiber cloth is lifted. At this time, the punching knife 1111 intermittently moves downwards to punch regular holes in the fiber cloth. When punching is not required, the opening cam 1112 rotates downwards, and at this time the fiber cloth passes through normally.

[0033] Specifically, for punching holes in the fiber cloth, precise control of the punching positions is required. After the fiber cloth is folded, the hole positions on each layer of the fiber cloth can correspond one by one, and the hole positions are designed according to the number of folded layers of the fiber cloth. For example, taking the fiber cloth in the middle position as the axis, the fiber cloth on both sides is punched, but the fiber cloth near the outer side is not punched. Thus, after the fiber felt is formed, a cavity is formed inside the fiber felt. Resin can be accommodated in the cavities formed by the holes in the multi-layer fiber cloth. The existence of the cavities can, on the one hand, accelerate the penetration of the resin between the layers and make the distribution of the resin more uniform, and on the other hand, the cavities can be filled with resin to improve the integrity after the fiber cloth is stacked and cured. The resin in the cavities after curing is equivalent to the reinforcing ribs erected in the middle of the fiber cloth, ensuring the overall direction and strength of the insulation felt and preventing the sliding between the layers of the insulation felt from causing a decrease in strength.

[0034] Further, as Figure 3 、 Figure 4 shown, the cutting member 112 includes two groups of cutting blades 1121 arranged symmetrically on both sides of the conveyor belt behind the punching member 111, a cutting knife 1122 arranged behind the cutting blades 1121, and a hinge plate 1123 for fixing the cutting blades 1121 and the cutting knife 1122 and hinged to the frame by a motor; It further includes a cutting knife 1124 arranged behind the cutting knife 1122 for overall cutting of the fiber cloth.

[0035] In this embodiment, the cutting knife 1124 is arranged to realize the slitting of each section of the fiber cloth. Each section of the fiber cloth can be used to manufacture a finished insulation felt. The cutting knife 1122 and the cutting blades 1121 are used to trim both sides of each section of the fiber cloth so that the uppermost layer can form a flange when the fiber cloth is folded.

[0036] Specifically, when the articulated plate 1123 is pressed down, the cutting disc 1121 contacts both sides of the fiber cloth, cuts both sides of the fiber cloth, and cooperates with the cutting knife 1122 to separate the waste from the fiber cloth. Finally, the rear section of each section of the fiber cloth is wider than the front section by a certain distance, and this distance should be able to completely cover the side surface of the finished heat insulation felt.

[0037] It should be noted that the length of each fold of the fiber cloth needs to be accurately calculated, and the length and width of the rear section should be larger. When the top layer is folded, flanges will be formed on all four sides of the top layer, that is, there will be an extra section, which is convenient for subsequent edge locking.

[0038] Furthermore, as Figure 5 、 Figure 6 shown, the gluing member 113 includes an upper gluing roller 1131 arranged behind the cutting member 112 and controlled to move by an electric cylinder, a supporting roller 1132 arranged obliquely below the rear side of the upper gluing roller 1131, and a lifting plate 1133 for fixing the upper gluing roller 1131 and the supporting roller 1132; a lower gluing roller 1134 arranged obliquely below the rear side of the supporting roller 1132 and controlled to move up and down by a telescopic cylinder, and a slide rail 1135 for driving the lower gluing roller 1134 to slide horizontally.

[0039] In this embodiment, by arranging the upper gluing roller 1131 and the lower gluing roller 1134 to coat the fiber cloth with resin, each layer of the fiber cloth can be evenly covered with resin when being folded.

[0040] Specifically, due to the folding method of the fiber cloth, which is in a sequential stacking manner, it is not possible to simply coat only one side of the fiber cloth. Also, considering the need to ensure the penetration efficiency and uniformity of the resin between layers, for each layer of the fiber cloth, the upper side of each layer of the fiber cloth is coated, so as to ensure the uniformity of the resin coated on each layer of the fiber cloth. Therefore, the upper gluing roller 1131 and the lower gluing roller 1134 are provided.

[0041] It should be noted that the upper glue roller 1131 is arranged above the fiber cloth, and the fiber cloth passes through the space between the upper glue roller 1131 and the supporting roller 1132. Taking the folding of the first, second, and third layers of fiber cloth as an example, the front end of the fiber cloth passes through the upper glue roller 1131. At this time, the upper end of the first layer of fiber cloth is coated with resin. Then, the lifting plate 1133 moves upward, and the upper glue roller 1131 disengages from the upper surface of the fiber cloth. The supporting roller 1132 lifts the fiber cloth. At this time, the lower glue roller 1134 rises and then moves forward along the slide rail 1135. While the lower glue roller 1134 moves, it drives the fiber cloth to move forward, so that the fiber cloth is folded while being coated. When the lower glue roller 1134 moves to the position, the coating is completed, and at the same time, the lower glue roller 1134 does not contact the third layer of fiber cloth located above. The lower glue roller 1134 returns to its original position. When the lower glue roller 1134 is coated to the halfway position, at this time, the third layer of fiber cloth is also brought to the folding position by the lower glue roller 1134. At this time, the upper glue pipe moves downward and approaches the supporting roller 1132 to coat the upper surface of the third layer of fiber cloth. This process is repeated.

[0042] It is worth mentioning that since the lower glue roller 1134 and the supporting roller are both located below the fiber cloth, the conveyor belt here should be set with a certain downward concave arc to accommodate the placement of the lower glue roller 1134 and the supporting rod.

[0043] Furthermore, as Figure 7 shown, the folding assembly 12 includes a pressing member 121 arranged behind the gluing member 113 and two groups of fixing members 122 respectively used to fix the front end and the rear end of the fiber cloth. Each group of fixing members 122 includes an adapter block arranged on both sides of the conveyor belt and controlled to lift by an electric cylinder, a pressing rod 1221 hinged to the adapter block by a motor, and a plurality of fixing needles 1222 arranged on the lower end surface of the pressing rod 1221; The pressing member 121 includes a pressing plate 1211 arranged at the rear end of the fiber cloth and provided with a plurality of fixing needles 1222 at the lower end. Both ends of the pressing plate 1211 are threadedly connected to the frame, and the slide rail 1135 drives the pressing plate 1211 to move up and down through a gear-rack transmission method. It also includes a needle roller 1212 arranged behind the pressing plate 1211.

[0044] In this embodiment, by setting the pressing rod 1221 and the pressing plate 1211 and cooperating with the fixing needles 1222, the fiber cloth is fixed, so that when the lower glue roller 1134 folds, the position can be ensured to be accurate and the fiber cloth at the bottom layer will not be dragged.

[0045] Specifically, after the fiber cloth moves to the folding position, the pressing rod 1221 presses down to fix the fiber cloth. The pressing rod 1221 is rotatably connected to the adapter block. Each time it folds, the pressing rod 1221 rises and then rotates, moves out of the fiber cloth, and then resets to re-fix. When the lower glue applicator roller 1134 moves to the farthest position, the pressing plate 1211 is driven to move upward through the transmission mode of the gear and rack, moving the fiber cloth under the pressing plate 1211. When the lower glue applicator roller 1134 returns to its position, the pressing plate 1211 moves downward to press and fix the newly folded fiber cloth.

[0046] It should be noted that while the pressing rod 1221 is set to play a fixing role, the pressing rod 1221 and the pressing plate 1211 are used to squeeze the folding and bending part of the fiber cloth to avoid the appearance of a hollow at the bending part.

[0047] It is worth mentioning that fixing needles 1222 are provided on both the pressing rod 1221 and the pressing plate 1211. The fixing needles 1222 are used to further fix the fiber cloth to avoid the resin on the surface of the fiber cloth coming into contact with the pressing rod 1221 and the pressing rod 1221, resulting in the lack of resin at the fixing position and affecting the molding.

[0048] A needling roller 1212 is arranged at the rear to pre-needle the folded fiber cloth, allowing the fiber cloth to pass through the middle of the needling roller. On the one hand, the needling roller 1212 forms extrusion on the fiber cloth to reduce the appearance of wrinkles or edge protrusions. On the other hand, through needling, the internal layers of the fiber cloth are initially fused to reduce the possibility of separation of each layer during the movement.

[0049] Furthermore, as Figure 8 、 Figure 9 shown, the edge-locking assembly 22 is arranged in front of the needling machine 21 and includes a positioning member 221 and a edge-closing member 222. The positioning member 221 includes restraint plates 2211 arranged on both sides of the conveyor belt. A lever is arranged at the end of the restraint plate 2211. Four groups of fixing plates 2212 arranged above the restraint plate 2211, a central frame 2213 vertically slidably connected to the center of the restraint plate 2211 controlled by a telescopic cylinder, an extension rod 2214 fixedly connected to each group of restraint plates 2211 and horizontally slidably connected to the central frame 2213, and a support rod 2215 vertically slidably connected to the middle of the central frame 2213.

[0050] The edge-closing member 222 includes two groups of control frames 2221 arranged outside the restraint plate 2211. Four groups of sliding plates 2222 are respectively slidably connected to the two groups of control frames 2221 through electric cylinders. The upper surface of the sliding plate 2222 is a smooth arc and the lower surface closely adheres to the surface of the conveyor belt.

[0051] In this embodiment, by setting the fixed plate 2212 and the sliding plate 2222, the treatment of the top layer frayed edge of the fiber cloth is realized, and the measured frayed edge is pressed down to form a hem, which is convenient for subsequent needle punching of the machine type.

[0052] Specifically, the folded fiber cloth enters the restraint plate 2211, stops moving after contacting the lever, and at this time the fiber cloth is located below the fixed plate 2212. The central frame 2213 moves downward, and both the support rod 2215 and the fixed plate 2212 contact the fiber cloth and continue to move. At this time, the fiber cloth jacks up the support rod 2215. As the support rod 2215 is jacked up, the extension rod 2214 slides outwards. At this time, the fixed plate 2212 moves outwards. The fixed plate 2212 pushes the wrinkles or protrusions on the edge of the fiber cloth flat and then moves downward along the edge of the fiber cloth, pressing down the frayed edge of the top layer of the fiber cloth. Then, the surrounding sliding plates 2222 move closer to the fiber cloth, and the pressed frayed edge is squeezed into the bottom of the fiber cloth by the sliding plates 2222 to complete the edge closing.

[0053] It should be noted that for hemming the four sides of the fiber cloth using the frayed edge, considering that the fiber cloth is stacked at this time, even if coated with resin, the bent parts of the fiber cloth still cannot be well combined together, and resin is coated between each layer. The resin is likely to seep out from the edge, resulting in an uneven and rough edge position of the finished product, which is not conducive to curing and forming.

[0054] Furthermore, as Figure 10 、 Figure 11 shown, the supplementary mechanism 3 is arranged behind the needle punching, and includes clamping plates 31 arranged on both sides of the conveyor belt for clamping the fiber felt, a support rod 32 arranged in the middle of the conveyor belt and controlled to lift by an electric cylinder, and an inclined roller 33 arranged above the support rod 32 and controlled to rotate along one end by a motor.

[0055] In this embodiment, by setting the support rod 32 and the inclined roller 33,; the fixed inclined roller 33 squeezes the excess resin towards the edge position, thereby promoting the resin to flow to the position of the frayed edge hemming.

[0056] Specifically, since only the folding surface is coated with resin during the folding stage, and the frayed edge position is not coated with resin, even after being needled by the needle punching machine 21, the side and the inside of the fiber felt still cannot be well combined together, and there may be a hollow phenomenon or the edge does not fit well with the inside, which is not conducive to subsequent curing and forming.

[0057] It should be noted that the support rod 32 is used to lift the middle of the fiber felt, and then the inclined roller 33 is used for rolling extrusion. With the cooperation of gravity, the resin flows to the surroundings and flows to the edge, combining with the fiber cloth at the edge.

[0058] Furthermore, as Figure 10 、 Figure 11As shown, the supplementary mechanism 3 further includes a top ring 34 disposed outside the support rod 32 and controlled by a motor to lift and lower, with a fixing needle 1222 provided on the upper surface, a turntable 35 for controlling the rotation of the top ring 34, and a needle punching plate 36 disposed outside the two groups of clamping plates 31 and controlled by an electric cylinder to move horizontally.

[0059] In this embodiment, the needle punching of the edge position of the fiber felt is achieved by setting the top ring 34 and the needle punching plate 36, which cooperates with the operation of the inclined roller 33 to make the combination of the resin and the fiber cloth closer.

[0060] Specifically, after the clamping plates 31 clamp the fiber felt, the needle punching plate 36 starts to move horizontally to punch the side surface of the edge of the fiber felt, and cooperates with the inflow of the resin to achieve the close combination of the resin and the fiber cloth. When the needle punching is completed, the top ring 34 rises to fix the fiber felt, then rotates 90°, turns the edge, and performs the same operation on the other two sides.

[0061] It should be noted that through needle punching, the combination of the flash and the interior is made closer, improving the integrity of the finished product and avoiding the phenomena of delamination and hollowing.

[0062] It is worth mentioning that this device adopts the method of applying glue first and then needle punching. The needle punching machine 21 uses the repeated puncture of the needles to realize the entanglement of the fibers. By applying glue first, the resin can better penetrate into the fibers by needle punching and be more evenly distributed.

[0063] Embodiment 2 As Figure 12 shown, the same or corresponding components as those in Embodiment 1 are labeled with the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 2 and Embodiment 1 is as follows: Furthermore, as Figure 12 shown, a carbon fiber heat insulation felt manufacturing and forming process is applied to a carbon fiber heat insulation felt manufacturing and forming device, including the following steps: Step 1, cutting step: Use the punching member 111 to punch regularly arranged holes in the middle of the fiber cloth, and then use the cutting member 112 to cut and trim the edge of the fiber cloth, cut off the excess parts on both sides of the fiber cloth, and perform slitting after cutting. One section of the cut fiber cloth completes the production of one heat insulation felt. Step 2, folding step: Fold the cut fiber cloth. First, apply resin to the upper surface of the bottom fiber cloth, then fix it with the fixing member 122, and then through the movement of the lower glue applicator roller 1134, while applying glue to the fiber cloth, fold the fiber cloth into a whole. Step 3: Needling step. The folded fiber cloth enters the edge-locking assembly 22. The central frame 2213 moves downward to fix the center of the fiber cloth. At the same time, the driving fixed plate 2212 presses down the excess flanges around the fiber cloth. Then, the flanges pressed downward are squeezed under the fiber cloth through the slide plate 2222 to achieve the tightening and edge-locking of the four peripheries. Then, it is input into the needling machine 21 for needling. Step 4: Supplementary step. The needled fiber cloth has become a complete fiber felt. The two sides of the fiber felt are clamped by the clamping plates 31, and then the strut 32 is propped up to make the fiber felt dry for heavy armor girls. The periphery becomes lower. By the rotation of the inclined roller 33, the resin in the middle is squeezed to the periphery. At the same time, the needling plate 36 outside the clamping plate 31 needles the side edges of the fiber felt. After the needling of the two sides is completed, the top ring 34 is propped up, the clamping plate 31 is loosened, the fiber felt is rotated 90°, and the fiber felt is clamped and needled again to complete the production and molding.
