Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber preparation, in particular to a preparation device and a preparation process of carbon fiber solid felt. Background Art

[0002] Carbon fiber felt is a felt-like material made of carbon fiber filaments through a special process. It has excellent properties such as light weight, high strength, high temperature resistance, corrosion resistance, and good conductivity. Carbon fiber felt is widely used in aerospace, sports equipment, automobile manufacturing and other fields. It is a high-performance composite material. In the processing of carbon fiber felt, it is necessary to soak it in a soaking liquid to solidify the carbon fiber felt.

[0003] Most of the existing carbon fiber felts are directly immersed in a resin aqueous solution during the felt solidification process. The effective ingredients in the static resin aqueous solution cannot fully contact the carbon fiber felt, and the carbon fiber curing efficiency is general. In addition, the surface material of the carbon fiber felt will fall off when it is immersed in the resin aqueous solution, and the fallen impurities cannot be cleaned in real time. The debris will be adsorbed on the carbon fiber during the felt solidification process, and the effect of carbon fiber felt solidification preparation is not good. Therefore, we propose a preparation device and preparation process for carbon fiber felt solidification. Summary of the invention

After the servo motor is working, it can drive the driving gear on the rotating shaft to rotate. Since the driving gear is meshed and connected with the driven gear plate, and the driven gear plate is rotatably connected with the bottom wall of the immersion tank through the bearing, the driven gear plate drives the installation component fixedly connected at the top and the carbon fiber felt bearing component connected with the installation component to rotate, and the carbon fiber felt in the carbon fiber felt bearing component can fully contact with the resin aqueous solution, thereby improving the curing efficiency of the carbon fiber felt.

[0022] 2. The recovery pump on the purification and recovery mechanism can recover the resin aqueous solution during the curing of the carbon fiber felt body and the debris dropped during the solidification of the carbon fiber felt body into the impurity removal box. The first filter screen, the second filter screen and the activated carbon layer in the impurity removal box filter and purify the debris in the resin aqueous solution. The delivery pump delivers the filtered and purified resin aqueous solution to the inner cavity of the immersion tank again, thereby reusing the resin aqueous solution and saving costs. It can also prevent the debris from being adsorbed on the carbon fiber felt body during solidification, thereby improving the effect of preparing the solidified carbon fiber felt body. Through the rotation of the rotating rod on the limit unit, the vertical sliding of the operating rod and the elasticity of the two sets of telescopic links and the compression spring, the lower pressure plate can be kept away from the first filter screen, the second filter screen and the activated carbon layer, thereby realizing the rapid disassembly and cleaning of the first filter screen, the second filter screen and the activated carbon layer, thereby avoiding blockage and affecting the recovery efficiency of the resin aqueous solution.

[0046] A preparation device and preparation process of carbon fiber solid felt comprises the following steps:

[0047] S1: First, the electrical ends of each electrical device are electrically connected to the external power supply and the electrical ends of the controller 8 through wires, and then the carbon fiber felt body to be fixed is placed between the adjacent hollow plates 703 on the carbon fiber felt bearing assembly 7, and the distance between the adjacent hollow plates 703 is adjusted by the sliding connection between the through holes on the hollow plates 703 and the screw 702, and then the position of the hollow plates 703 is fixed by the threaded connection of the tightening nut 704 on the screw 702 to achieve the fixation of the carbon fiber felt body, and then a certain amount of resin aqueous solution is poured into the soaking tank 3, and the controller 8 controls the cylinder 6 to work, and the cylinder 6 drives the carbon fiber felt body fixed on the carbon fiber felt bearing assembly 7 into the soaking tank 3 through the piston rod;

[0048] S2: When the bottom of the lower circular plate 701 on the carbon fiber felt bearing assembly 7 fits with the top of the fixing seat 110 on the mounting component 11, the two groups of clamping grooves 705 on the lower circular plate 701 are aligned with the two groups of clamping blocks 117, and the controller 8 controls the stepper motor 111 to work. The work of the stepper motor 111 drives the bidirectional screw rod 112 to rotate. After the two groups of threaded blocks 113 threadedly connected with the bidirectional screw rod 112 pass through the sliding groove 114 and the sliding block 115, the adjacent side clamping plates 116 move in relative directions until the two groups of clamping blocks 117 are respectively connected with the two groups of clamping grooves 705.

[0049] S3: Finally, the controller 8 controls the servo motor 12 to work, and the work of the servo motor 12 drives the driving gear 9 on the rotating shaft to rotate. Since the driving gear 9 is meshed and connected with the driven gear plate 10, and the driven gear plate 10 is rotatably connected to the bottom wall of the immersion tank 3 through the bearing, the driven gear plate 10 drives the mounting component 11 fixedly connected to the top and the carbon fiber felt bearing assembly 7 connected to the mounting component 11 to rotate, and the carbon fiber felt in the carbon fiber felt bearing assembly 7 can fully contact with the resin aqueous solution, thereby improving the curing efficiency of the carbon fiber felt;

[0050] S4: While the carbon fiber felt is being cured, the controller 8 controls the recovery pump 401 and the delivery pump 404 on the purification recovery mechanism to work simultaneously. After the recovery pump 401 works, the suction pipe 402 generates suction, and the resin aqueous solution during the curing of the carbon fiber felt and the debris dropped during the solidification of the carbon fiber felt are recovered to the inner cavity of the impurity removal box 400 through the reflux pipe 403. The first filter screen 4007, the second filter screen 4008 and the activated carbon layer 4009 in the impurity removal box 400 filter and purify the debris in the resin aqueous solution.
