Description

Technical Field

[0001] This utility model relates to the field of carbon fiber prepreg production equipment, and in particular to a carbon fiber prepreg stacking molding production equipment. Background Technology

[0002] Carbon fiber prepreg is a composite material in which epoxy resin is bonded to carbon fiber using a stacking technology. Carbon fiber prepreg is mainly composed of carbon fiber, epoxy resin, release paper and other materials, and is processed through impregnation, drying, coating, cooling and winding.

[0003] The carbon fibers used in carbon fiber prepregs are usually wound in bundles on a winding drum. In the production of carbon fiber prepregs, the carbon fiber bundles can be woven into carbon fiber cloth and then mixed with epoxy resin to form carbon fiber prepregs. Existing compression molding equipment is not very efficient in the production of carbon fiber prepregs and has a poor pre-expansion effect on the carbon fiber cloth, which can easily lead to poor thickness uniformity of the carbon fiber prepregs and affect the quality of the carbon fiber prepregs.

This arrangement increases the stroke and the contact area between the carbon fiber prepreg and the cooling roller 910, thereby ensuring good cooling effect. The inlets 930 and outlets 940 of the cooling rollers 910 are respectively connected to a cooling circulating water system.

[0040] Please see Figure 9 and Figure 10In one example of the carbon fiber prepreg compaction production equipment of this utility model, the winding device 1100 includes a winding bracket 1130. The top of both sides of the winding bracket 1130 is provided with upward-opening U-shaped grooves 1131. A bearing 1111 is rotatably mounted at each end of the winding shaft 1110. The two bearings 1111 are respectively installed in the two U-shaped grooves 1131. A fastening bolt 1132 is threaded onto each of the two U-shaped grooves 1131. The two fastening bolts 1132 are respectively... The first gear 1133 is rotatably mounted on the winding bracket 1130 on the lower side of the U-shaped groove 1131, and the second gear 1112 is fixedly mounted on one end of the winding shaft 1110. The first gear 1133 meshes with the second gear 1112. The first sprocket 1134 is fixedly mounted on the end face of the first gear 1133 away from the winding bracket 1130. The fourth drive motor 1120 is drivenly connected to the first sprocket 1134. The output of the fourth drive motor 1120 drives the first sprocket 1134 and the first gear 1133 to rotate. The first gear 1133 drives the second gear 1112 to rotate the take-up shaft 1110. After loosening the two fastening bolts 1132, the two bearings 1111 can be removed from the two U-shaped grooves 1131, facilitating unwinding. Then, the two bearings 1111 of the other take-up shaft 1110 are respectively placed into the two U-shaped grooves 1131, and the two fastening bolts 1132 are tightened to fix the two bearings 1111 in the two U-shaped grooves 1131. The take-up shaft 1110 is an air-expansion shaft.
