Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tapes, in particular to a cutting device for thermal insulation adhesive tapes in extremely cold areas. Background Art

[0002] For the thermal insulation tape used in extremely cold areas, an insulation layer will be set inside the tape to isolate the temperature. The insulation layer can be a glass fiber layer and a kraft paper layer, etc. An aluminum foil layer will also be set on the surface of the tape. Due to the arrangement of such structural layers, the strength of the tape itself is relatively high, which may cause problems such as difficulty in tearing. Therefore, the tape needs to be cut by a cutting device when in use.

[0003] The current cutting device is not suitable for the use of thermal insulation tape and cannot be cut quickly. If tools such as scissors are used, it will be inconvenient for staff to operate and affect work efficiency. Utility Model Content

The cutting device is designed in a novel manner, wherein the elastic telescopic rod between the lower base and the upper cutting seat is designed to have a telescopic clamping function, so that the cutting device can be installed on the outside of the tape body. When the outer diameter of the tape body is reduced as the tape body is used, the upper cutting seat can always be in close contact with the outer layer of the tape, thereby ensuring the tightness of the tape roll and the stability of the connection between the two.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
