[0001] The utility model relates to the field of copper and copper alloy processing, in particular to a paper sleeve cutting device. Background Art

[0002] For finished copper and copper alloy products, after longitudinal slitting and stripping, they are shipped in rolls. Paper sleeves are required for the finished product slitting process, and the strips are wrapped around the paper sleeves before delivery to the user.

The rotating roller 21 comprises a roller shaft, a roller body, and a bearing. It is fixed to the vertical surface of the frame 1 near the transmission side via the support 22, at a 30° angle to the vertical. The support 22 is connected to the frame 1.

[0043] In some embodiments of the present invention, the first cylinder 35 is fixed below the roller frame 34 to play a supporting role. At the same time, it can serve as a "gas spring" to convert absolute rigid contact into relatively flexible contact during use, so that the paper sleeve can be tightened under the action of the pressure roller 31 and the support roller without being stuck.

[0044] In some embodiments of the present invention, the first cylinder 35 is an SC50*50 cylinder with a maximum thrust of 80 kg. The thrust can be adjusted by a pressure reducing valve.
