Description

Technical Field

[0001] This utility model relates to the technical field of raw material tape processing equipment, and more specifically, to a raw material tape slitting thickness online adjustment device. Background Technology

[0002] Raw material tape, also known as water-based adhesive tape or raw rubber tape, is a white film-like sealing material with polytetrafluoroethylene (PTFE) as its main component. It is widely used for sealing pipe connections. Raw material tape slitting machines are used to cut wide raw material tape materials (such as PTFE raw material tape) into narrow tapes of a specific width. Their core function is to achieve efficient and precise slitting processing.

[0003] In existing technologies, most slitting machines can only produce raw material tape of a fixed thickness, thus requiring the purchase of multiple slitting machines with different thicknesses, which greatly increases production costs. Furthermore, after cutting large raw material tapes into tapes of the required thickness, the slitting tapes can only be wound up individually, and the edge material cannot be wound up at the same time. The resulting edge material cannot be effectively recycled, and the spacing of the slitting blades cannot be adjusted online in real time. Operators need to repeatedly start the slitting equipment, which greatly reduces work efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
