Description

Technical Field

[0001] The utility model relates to the technical field of cutting of strapping tape processing, in particular to a cutting mechanism which is convenient for strapping tape processing. Background Art

[0002] Plastic strapping tape is widely used and promoted in the packaging industry due to its excellent physical properties such as good elastic recovery, high strength, good water resistance, strong chemical resistance, light weight and softness. In the process of strapping tape processing, a cutting mechanism that is convenient for strapping tape processing is needed to cut it;

[0003] There may be two problems when using it. First, in the prior art, the strapping tape is moved by a plurality of rotatable guide rollers, but the guide rollers can only rotate and it is difficult to adjust the position, making it difficult for the existing device to transmit strapping tapes of different thicknesses, and thus narrowing its scope of use. Second, after the strapping tape is moved, the staff needs to manually cut it according to the required length, which reduces the work efficiency. Therefore, we propose a cutting mechanism that is convenient for strapping tape processing. Utility Model Content
