Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber impregnation cloth rolling, in particular to a carbon fiber impregnation cloth rolling device. Background Art

[0002] Carbon fiber prepreg is produced by processes such as spinning, hot pressing, cooling, and laminating of carbon fiber yarn impregnated with resin, release paper, etc. In the production process of carbon fiber prepreg, the pressing mechanism is an important equipment, which makes the carbon fiber prepreg bonded together and forms a carbon fiber prepreg of a certain thickness through the heating and pressure of the pressing roller.

[0003] The traditional pressing mechanism is generally composed of a plurality of pressing roller groups, each of which includes an upper pressing roller and a lower pressing roller. The carbon fiber prepreg in production is carried on the release paper and moves along the joint surface between the upper pressing roller and the lower pressing roller. Since the contact time between the carbon fiber prepreg carried on the release paper and the pressing roller is short, the carbon fiber prepreg is heated for a short time. To a certain extent, the bonding temperature of the carbon fiber prepreg is low, affecting the quality of the final carbon fiber prepreg cloth. Generally, a heating plate is set between the pressing roller groups, and the prepreg cloth is contacted with the heating plate for secondary heating. However, since the fiber prepreg cloth has a certain water content when it is rolled, the more contact surface with the equipment, the greater the probability of stains adhering to it.
