Described elastic cushion layer and described arc match.
Beneficial effect using technique scheme is:Cylinder be circumferentially with concave slot, the section of head part is convex, top
Part is matched with concave slot, and spring is located between cylinder and head part, and head part along the circumferential movement of cylinder, works as adhesive tape in concave slot
When volume is set in cylinder, due to head part and cylinder circumference elastic movement, when adhesive strips contact head part, head part is compressed, wait tape roll
It is completely nested, head part Elastic Contact tape roll, and circumference clamping tape roll in the presence of the elastic force of spring, it is to avoid tape roll
The adhesive tape of both sides is wound around many situations few on one side on one side, greatly reduces the percent defective of production, reduces the production cost of enterprise, carry
High efficiency.

Specific embodiment
With reference to specific embodiment, content of the present utility model is described in further detail:
In order to reach the purpose of this utility model, as illustrated, in a kind of embodiment of the present utility model being:A kind of use
In the tape roll fixing device of adhesive tape cutting machine, including 1,4 head parts of cylinder 2 (be not limited only to 4, circumferentially equally distributed
Multiple is also permissible) and spring 3, cylinder 1 is cylinder, and cylinder is circumferentially with the concave slot 12 that 4 sections are convex, top
The section of part 2 is convex, and head part 2 is located in the concave slot 12 of cylinder, and head part 2 is matched with concave slot 12, and spring 3 is located at cylinder
Between 1 and head part 2, head part 2 along the circumferential movement of cylinder 1, is provided with the first spring mounting hole in concave slot 12 in concave slot 12
14, head part 2 is provided with second spring installing hole 21, and the first spring mounting hole 14 is coaxially disposed with second spring installing hole 21 and is
