An inner support cylinder sleeve 32 is inserted on the support retaining ring 312. A plurality of arc-shaped connecting pieces 321 extending leftward are formed on the left end face of the inner support cylinder sleeve 32. The connecting pieces 321 pass through the retaining disc 31 and are fixedly connected to a circular sleeve seat 34;

[0021] An outer support cylinder sleeve 33 is arranged on the right side of the inner support cylinder sleeve 32. A cutting ring groove a is arranged between the outer support cylinder sleeve 33 and the inner support cylinder sleeve 32. A connecting ring 331 extending leftward is formed on the inner circle at the left end of the outer support cylinder sleeve 33. The connecting ring 331 is inserted and fixed in the inner support cylinder sleeve 32; A connecting bracket 36 is inserted and fixedly connected in the outer support cylinder sleeve 33. A transverse adjusting stud 35 is screwed in the middle of the connecting bracket 36. The right end of the adjusting stud 35 is pivotally connected to the retaining disc 31. Thus, by rotating the adjusting stud 35, the axial movement of the outer support cylinder sleeve 33 and the inner support cylinder sleeve 32 can be driven.

[0022] The central axis of the retaining disc 31 coincides with the central axis of the support retaining ring 312. The diameter of the outer wall of the support retaining ring 312 is equal to the diameter of the inner wall of the inner support cylinder sleeve 32. The diameter of the inner wall of the inner support cylinder sleeve 32 is greater than the diameter of the inner wall of the outer support cylinder sleeve 33. The outer wall of the outer support cylinder sleeve 33 and the outer wall of the inner support cylinder sleeve 32 are in the same cylindrical surface, which is convenient for sleeving the paper barrel to be slit on the rotating head 3.

A clamping handle 350 is inserted and fixed on the externally threaded adjusting sleeve 340 on the left side of the socket 34; When the paper barrel is not sleeved, the clamping airbag 38 is in a contracted state and its outer ring does not extend out of the outer wall of the outer support cylinder sleeve 33; When the paper barrel is sleeved on the rotating head 3, by rotating the externally threaded adjusting sleeve 340, the pressing plate 330 is driven to move rightward, and then the pressing plate 330 compresses the pressure stabilizing airbag 320, enabling the gas in the pressure stabilizing airbag 320 to flow into the clamping airbag 38 through the positioning connecting pipe 310 and the air pipe 39, causing the clamping airbag 38 to expand and clamp the inner wall of the paper barrel, realizing the positioning and fixation of the paper barrel on the rotating head 3;

[0026] At the same time, an elastic reset lining member, such as a porous memory rubber member, can be arranged in the pressure stabilizing airbag 320; When the pressing plate 330 moves away from the pressure stabilizing airbag 320, the memory rubber member can cause the pressure stabilizing airbag 320 to reset, and then the clamping airbag 38 contracts and no longer clamps the paper barrel, and the cut paper barrel can be removed.

[0027] A plurality of sealing rings are inserted and fixed on the outer wall of the left end of the air pipe 39, and the sealing rings are pressed against the inner wall of the positioning connecting pipe 310.

[0028] The connecting bracket 36 includes an annular hub portion. A plurality of spokes are formed on the outer wall of the hub portion.

[0030] Working principle: This device is a slitter for making paper barrels, and the technical point of the slitter lies in the rotating head 3; the position adjustment of the cutting annular groove a can be achieved by rotating and adjusting the screw 35.

[0031] Moreover, the rotating head 3 of the device adopts an airbag structure to clamp the paper barrel loaded on the rotating head 3. The clamping airbag 38 expands to achieve the positioning and clamping of the paper barrel, facilitating the rotary slitting of the paper barrel; when the clamping airbag 38 contracts, it can be disengaged from the paper barrel, facilitating the removal or sleeving of the paper barrel from the rotating head 3.
