Description

Technical Field

[0001] The utility model relates to the technical field of cutting mechanisms, in particular to a strip cutting mechanism. Background Art

[0002] The cutting mechanism of the warning strip tape is a key component used to cut the continuous coil into strip products during the production process. This mechanism is very important when producing products such as signs, warning tapes, labels, etc. In the production of warning strip tapes, the design and performance of the cutting mechanism are directly related to production efficiency and product quality. Therefore, manufacturers need to carefully consider the characteristics of the material, production requirements and safety standards when selecting and designing the cutting mechanism.

[0003] The current strip warning tape cutting mechanism usually lacks a fixing structure for the tape body during the cutting process, which makes the tape body easy to move during the cutting process, resulting in an uneven cut; therefore, we propose a strip tape cutting mechanism to solve this problem.
