Description

Technical Field

[0001] This utility model relates to the field of tarpaulin production technology, specifically to a tarpaulin cutting tool. Background Technology

[0002] During the production of tarpaulins, a large number of narrow strips of tarpaulin are generated after cutting according to product specifications. These narrow strips are not waste materials, but can be reused through secondary processing: for example, they can be cut into small rainproof cloths (such as rainproof covers for electric vehicles and tool storage covers), used as spare materials for tarpaulin repair, or made into narrow protective curtains (such as warehouse shelf divider curtains).

[0003] Therefore, narrow strip tarpaulins need to be rolled up and stored first, and then processed according to the needs of secondary use. The core processing steps include edge trimming to remove the rough edges left after cutting and to ensure safety in use; and precise cutting of different widths to adapt to the needs of diverse small-sized products.

[0004] Regarding the cutting requirements of narrow strip tarpaulin rolls, the inventors believe that there is currently no convenient cutting tool specifically designed for narrow strip tarpaulin rolls in the industry. Therefore, how to develop a dedicated convenient cutting tool that meets this requirement has become a technical problem that urgently needs to be solved by people in this field.
