Description

Technical Field

[0001] The present invention belongs to the technical field of carbon fiber infiltration equipment. Specifically, it particularly relates to a carbon fiber infiltration equipment and a liquid amine infiltration method for carbon nanofibers. Background Art

[0002] Carbon fiber needs to undergo a pre-impregnation process to improve its performance. By mutually impregnating with thermoplastic and thermosetting resins, and then through processes such as extrusion and drawing, a new type of thermoplastic composite material with high strength, high toughness, and recyclability is formed;

[0003] When the carbon fiber wire harness is infiltrated, the infiltration solvent is a resin mixed solvent. The solvent has adhesiveness. During the movement of the infiltrated carbon fiber, it will carry the infiltration solvent. When the carbon fiber wire harness is hot-pressed, the excess resin infiltration solvent is extruded and accumulates near the extrusion point. The resin infiltration solvent accumulates and hardens at the extrusion inlet, contacts the infiltrated carbon fiber wire harness, scrapes off the infiltration solvent of the carbon fiber wire harness, reduces the infiltration solvent of the carbon fiber wire harness, and has a low hot-pressing effect, resulting in a reduction in the product qualification rate; usually, to clean the excess resin infiltration solvent, the machine needs to be stopped for cleaning, which reduces the working efficiency.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a carbon fiber wetting equipment and a liquid amine wetting method for carbon nanofibers, which have the following beneficial effects:

[0022] 1. The movement of the upper pushing plate drives the movement of the upper shoveling plate. The bottom end of the upper shoveling plate is slightly higher than the carbon fiber wire harness. During the movement of the upper shoveling plate, the excess resin wetting solvent generated by the hot pressing of the carbon fiber and the hot pressing roller is shoveled onto the top surface of the upper shoveling plate. The moving cleaning plate moves periodically to push the resin wetting solvent on the top surface of the upper shoveling plate into the collection box. The movement of the lower pushing plate drives the horizontal movement of the lower shoveling plate. During the movement of the lower shoveling plate, the excess resin wetting solvent generated by the hot pressing of the carbon fiber and the hot pressing roller is shoveled onto the bottom surface of the lower shoveling plate, and the resin wetting solvent finally falls onto the top surface of the lower moving plate; the excess resin wetting solvent extruded is cleaned to prevent the resin wetting solvent from accumulating and hardening at the extrusion inlet and contacting the wetting carbon fiber wire harness, scraping the solvent wetting the carbon fiber wire harness, reducing the wetting solvent of the carbon fiber wire harness, reducing the hot pressing effect, resulting in a decrease in the product qualification rate, and improving the processing efficiency.

[0023] 2. During discharging, the moving connecting block moves to the position closest to the material receiving cylinder. The material receiving cylinder pushes out the material receiving moving block. The material receiving moving block drives the material receiving ejector rods and the material receiving boxes to move. The material receiving ejector rods contact and squeeze the discharge moving plate and the lower moving plate respectively. The discharge moving plate moves, so that the resin wetting solvent falls from the collection box. The lower moving plate moves, and the resin wetting solvent on the top surface of the lower moving plate falls. The discharged resin wetting solvent is discharged and collected without stopping the machine, improving the working efficiency.

[0024] 3. The infiltration motor drives the infiltration brush to rotate. The infiltration brush brushes the resin infiltration solvent to the bottom end of the carbon fiber wire harness, so that the carbon fiber wire harness is ensured to be infiltrated with a sufficient amount of resin infiltration solvent, ensuring the subsequent hot pressing effect and reducing the defective rate.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The wetting motor 102 drives the wetting brush 101 to rotate, and the wetting brush 101 brushes the resin wetting solvent to the bottom end of the carbon fiber wire harness, ensuring that the carbon fiber wire harness is infiltrated with a sufficient amount of resin wetting solvent, guaranteeing the subsequent hot pressing effect and reducing the defective rate.

[0060] Example Nine, please refer to Figure 8 , Figure 9 , the outer contours of the discharging moving plate 3113 and the lower moving plate 3203 are smaller than the inner contour of the receiving box 3403;

[0061] During receiving, ensure that the resin wetting solvent does not fall outside the receiving box 3403.

[0062] A liquid amine wetting method for carbon nanofibers uses the above carbon fiber wetting equipment.

[0063] In summary, by means of the above technical solution of the present invention, when using this device, the impregnation tank 1 soaks the carbon fiber wire harness. After impregnation, the carbon fiber wire harness is removed from the impregnation tank 1. When passing through the roller, the bottom end of the carbon fiber wire harness will contact the roller, reducing the resin impregnation solvent at the bottom end of the carbon fiber wire harness. The impregnation motor 102 drives the impregnation brush 101 to rotate, and the impregnation brush 101 brushes the resin impregnation solvent onto the bottom end of the carbon fiber wire harness; the hot pressing roller 2 rotates to hot press the carbon fiber wire harness. During the hot pressing process, the excess resin mixed solvent will be extruded and accumulate at the upper and lower ends of the carbon fiber wire harness on the side of the hot pressing roller 2 close to the impregnation tank 1. The moving motor 3303 drives the moving screw rod 3302 to rotate, driving the moving connection block 3304 to move. The moving connection block 3304 drives the collection box 3104 to move. The collection box 3104 drives the upper push plate 3101 to move. The upper push plate 3101 drives the upper shovel plate 3102 to move. The bottom end of the upper shovel plate 3102 is slightly higher than the carbon fiber wire harness. During the movement of the upper shovel plate 3102, the excess resin impregnation solvent generated by the hot pressing of the carbon fiber and the hot pressing roller 2 is shoveled onto the top surface of the upper shovel plate 3102. The rotation motor 3112 drives the rotation screw rod 3111 to rotate, driving the cleaning moving block 3105 to move in the direction close to the rotation motor 3112. The cleaning moving block 3105 drives the moving cleaning plate 3103 to move through the cleaning moving rod 3106, pushing the resin impregnation solvent on the top surface of the upper shovel plate 3102 into the collection box 3104. When the cleaning moving block 3105 moves to one end of the collection moving port, the cleaning cylinder 3110 drives the cleaning pull rod 3109 to move upward. The cleaning pull rod 3109 pulls the cleaning moving rod 3106 to move, and the moving cleaning plate 3103 moves upward. The cleaning pull spring 3108 stretches. The rotation screw rod 3111 rotates, driving the cleaning moving block 3105 to move in the direction away from the rotation motor 3112. When the cleaning moving block 3105 moves to the other end of the collection moving port, the cleaning pull spring 3108 resets, the cleaning moving rod 3106 moves downward, and the moving cleaning plate 3103 contacts the upper shovel plate 3102. Through the periodic movement of the moving cleaning plate 3103, the resin impregnation solvent is pushed into the collection box 3104. The moving motor 3303 drives the moving screw rod 3302 to rotate, driving the moving connection block 3304 to move. The moving connection block 3304 drives the lower connecting plate 3204 to move. The lower connecting plate 3204 drives the lower push plate 3201 to move. The lower push plate 3201 pushes the lower shovel plate 3202 to move. During the movement of the lower shovel plate 3202, the excess resin impregnation solvent generated by the hot pressing of the carbon fiber and the hot pressing roller 2 is shoveled onto the bottom surface of the lower shovel plate 3202. The resin impregnation solvent slides along the lower arc plate 3205 to the top surface of the lower moving plate 3203;During discharging, the movable connecting block 3304 moves to the position closest to the material receiving cylinder 3404. The material receiving cylinder 3404 pushes out the material receiving movable block 3401. The material receiving movable block 3401 drives the material receiving ejector rod 3402 and the material receiving box 3403 to move. The material receiving ejector rod 3402 contacts and presses against the discharging movable plate 3113 and the lower movable plate 3203 respectively. The discharging movable plate 3113 moves, and the upper discharging spring 3115 stretches, causing the resin-infiltrated solvent to fall from the collection box 3104. The lower movable plate 3203 moves, and the lower discharging spring 3208 stretches, causing the resin-infiltrated solvent on the top surface of the lower movable plate 3203 to fall.
