Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically a slitting machine for producing waterproof tape with easily adjustable slitting spacing. Background Technology

[0002] Adhesive tape is a sticky strip material composed of a substrate, adhesive, and auxiliary materials (such as release paper / film). It is widely used in packaging, fixing, insulation, sealing and other scenarios. Waterproof tape is a branch of adhesive tape, and it is a type of tape with waterproof, sealing and moisture-proof functions as its core functions.

[0003] Chinese Patent Publication No. CN 116715076 A discloses a high-efficiency tape slitting machine, specifically relating to the field of tape production technology. It includes a support base frame, two symmetrically distributed protective side frames fixedly installed on one side of the top of the support base frame, a connecting plate fixedly installed between the two protective side frames, a cylindrical masterbatch on one side of the protective side frame, and a tape winding mechanism fixedly installed on the side of the protective side frame away from the cylindrical masterbatch.
