Description

Technical Field

[0001] The invention relates to the technical field of prepreg slitting, and in particular to a cutting device of a prepreg slitting machine. Background Art

[0002] The cutting device of the prepreg slitting machine mainly cuts the carbon fiber material of the prepreg into different widths through the designed upper and lower bottom knives and the automatic knife alignment structure to ensure the cutting accuracy.

[0003] The existing cutting knife device is mainly composed of a main body base, an upper knife lifting device, an upper knife and bottom knife fixing and adjusting device, a bottom knife operation control device, etc. The upper knife is directly installed on the main shaft and fastened by a retaining ring processed on one side. The installation principle of the lower knife is the same as that of the upper knife, and the whole is installed on the base. The upper knife shaft can be raised and lowered by a turbine lift to engage the lower knife to cut the carbon fiber prepreg with equal width.
