[0002] With the rapid development of the packaging industry and the intensification of market competition, technological innovation is the key driving force for the development of the tape slitting and winding device industry. Tape slitting and winding technology is a technology that accurately divides and rewinds large rolls of packaging tape according to specific lengths and widths. With the improvement of automation and the rapid development of the packaging industry, tape slitting and winding technology has gradually become a key link in improving production efficiency and reducing labor costs. The slitting and winding process requires precise control of cutting length, speed and angle to ensure that each piece of tape meets product packaging requirements.

[0003] When adjusting the cutter of the existing tape slitting and winding device, most of the devices need to replace the cutter rod with different spacings as a whole, and the fixing operation is cumbersome.
