The fixing strip 5 is integrally formed on the inner wall of the base sleeve 4. A collar 6 is fixed at the opening of the tube, and a lug plate 7 protrudes from the inner ring of the collar 6. The lug plate 7 is locked to the outer end of the support shaft 2 by bolts. A tubular airbag 9 is attached to the outer tube of the base sleeve 4. Metal protective strips 10 are fixed in a ring-shaped distribution on the outer wall of the tubular airbag 9. An inner bladder layer 13 and a core bladder layer 14 are arranged in sequence from the inner wall of the tubular airbag 9 near the metal protective strips 10. A layer of ribs 15 is integrally formed between the inner bladder layer 13 and the core bladder layer 14. A pneumatic quick connector 12 is installed on the body of the tubular airbag 9 near the collar 6.
[0027] The inner bladder layer 13 is connected to the inner bladder wall of the tubular airbag 9, and twelve sets of ribs 15 are arranged in a ring between the inner bladder layer 13 and the core bladder layer 14.
[0028] By adopting the above technical solution, the inner bladder layer 13 and the inner bladder wall of the tubular airbag 9 can be connected by adhesive bonding. Then, the inner bladder layer 13 can be connected to the core bladder layer 14 by means of a number of layer ribs 15 to form an internal support structure, thereby improving the support thickness and strength of the tubular airbag 9 when it expands towards the metal protective protrusion 10.
[0029] Among them, the fixed strip 5 is provided in three sets on the inner tube wall of the base sleeve 4, and the fixed groove 8 is provided in three sets on the shaft surface of the support shaft 2.
[0030] By adopting the above technical solution, the base sleeve 4 can be positioned and locked in the three sets of fixed grooves 8 of the support shaft 2 by the three sets of fixed strips 5, so as to ensure that the base sleeve 4 can obtain stable support at the support shaft 2.
[0031] The lug plate 7 has a through hole on its surface and a screw hole on the end face of the support shaft 2 on one side of the lug plate 7. A bolt is screwed between the through hole of the lug plate 7 and the screw hole of the support shaft 2.

[0034] By adopting the above technical solution, the tubular airbag 9 can be screwed onto the pneumatic quick connector 12 via the rigid pipe 11, so that the tubular airbag 9 can be connected to the pipeline of the external air supply equipment through the pneumatic quick connector 12 to obtain a controllable expansion air source, so that compressed gas can be introduced into or discharged from the tubular airbag 9.
[0035] The metal protective strip 10 is an arc-shaped strip, and the metal protective strip 10 is bonded and fixed to the outer wall of the tubular airbag 9 with its inner arc surface.
[0036] By adopting the above technical solution, the arc-shaped strip of the metal guard 10 is bonded to the outside of the tubular airbag 9 to form an expanded outer protective layer, so that the tubular airbag 9 has an outer protective structure when it expands to support the industrial paper tube for slitting, preventing the paper tube slitting tool from cutting the tubular airbag 9.
[0037] It should be noted that this utility model is an anti-deformation device for industrial paper tube slitting. After the support cutting mechanism 3 is set at the support shaft 2 of the main shaft box 1 of the paper tube slitting machine, the base sleeve 4 of the support cutting mechanism 3 can be positioned and fitted outside the support shaft 2 with the help of the fixing strip 5. Then, the lug plate 7 at the collar 6 is attached to the shaft end of the support shaft 2. The bolt can pass through the through hole of the lug plate 7 and be screwed into the screw hole of the support shaft 2, thereby installing the lug plate 7, the collar 6 and the base sleeve 4 outside the support shaft 2. Then, the tubular airbag 9 can be screwed to the pneumatic quick connector 12 with the rigid pipe 11, so that the tubular airbag 9 can be connected to the pipeline of the external air supply equipment through the pneumatic quick connector 12 to obtain a controllable expansion air source, so that compressed gas can be introduced into or discharged from the tubular airbag 9. Different diameter industrial paper tubes need to be fitted. When the paper tube is being cut by the paper tube slitting machine outside the support shaft 2, the paper tubes of the same batch can first be taken out as individual tubes and put on the outside of the tubular air bag 9. Then, an external controllable air source is connected at the pneumatic quick connector 12 to inflate the tubular air bag 9. After the tubular air bag 9 is inflated, the supporting metal guard 10 expands outward to contact the inner wall of the paper tube for support. Then, the air pipe at the pneumatic quick connector 12 is pulled out. The cutter of the paper tube slitting machine can cut the paper tube step by step under the control of the CNC system. During the cutting, the support of the tubular air bag 9 and the metal guard 10 makes the paper tube less likely to be deformed at the cutting position due to cutting force. The expansion range of the tubular air bag 9 is adjustable, so that the support shaft 2 can adapt to the support of paper tubes of different diameters. After the cutting is completed, multiple sections of paper tube can be pulled away from the support shaft 2 from the outside of the metal guard 10.
