The limiter includes a sleeve 4, one end of which is provided with a limiter ring 6, which is coaxial with the sleeve 4, and can be sleeved on the outside of the glue roller nut for limiting; a limiter column 7 is provided inside the limiter ring 6, and the limiter column 7 can be engaged with the groove on the side wall of the glue roller nut. The limiter ring 6 and the limiter column 7 cooperate with each other to limit the glue roller nut and provide a fulcrum for disassembling the glue roller nut. Preferably, the outer diameter of the sleeve 4 is 12 mm, the inner diameter is 10.39 mm, the length of the sleeve 4 is 290 mm, and the overall length of the limiter is 358 mm.

[0030] The disassembly part includes a connecting rod 11 located inside the sleeve 4. A long hexagonal wrench 8 is provided at one end of the connecting rod 11. The radial cross section of the long hexagonal wrench 8 is a regular hexagon. A first handle 9 is provided at the other end. The first handle 9 is perpendicular to the axis of the connecting rod 11, which is convenient for the staff to apply force. The long hexagonal wrench 8 passes through the sleeve 4 and is located at the center of the limit ring 6. The long hexagonal wrench 8 is engaged with the screw inside the nut of the rubber roller. The distance between the first handle 9 and the long hexagonal wrench 8 is greater than the length of the sleeve 4, ensuring that the first handle 9 can rotate freely when the long hexagonal wrench 8 is engaged with the screw. Preferably, the outer diameter of the connecting rod 11 is 10 mm, the length of the connecting rod 11 is 358 mm, and the total length of the disassembly part is 366.30 mm.

[0031] The blade of the cigarette making machine for cutting cigarettes is fixed with a blade nut, and a gasket is provided between the blade nut and the blade, which makes it inconvenient to disassemble the blade nut. The utility model also includes a fixing part, which includes an outer sleeve 1 sleeved on the outside of the sleeve 4, and the outer sleeve 1 and the sleeve 4 can slide and rotate. The outer sleeve 1 is provided with a clamping device at one end away from the limiting ring 6, and the clamping device includes a semicircular ring clamping block 2, and the inner diameter of the semicircular ring clamping block 2 is larger than the outer diameter of the connecting rod 11. The remaining semicircular ring gap is convenient for the first handle 9 to rotate, and the semicircular ring clamping block 2 can clamp the gasket in front of the blade. The sleeve 4 is provided with an inner hexagonal wrench 10 at one end away from the limiting ring 6, and the outer diameter of the inner hexagonal wrench 10 is smaller than the inner diameter of the semicircular ring clamping block 2, and the inner hexagonal wrench 10 can be engaged with the outer side of the blade nut. A second handle 5 is provided on the side wall of the sleeve 4 close to the limiting ring 6, and the second handle 5 is perpendicular to the axis of the sleeve 4. A third handle 3 is provided on the side wall of the outer sleeve 1, and the third handle 3 is perpendicular to the axis of the outer sleeve 1. The length of the outer sleeve 1 is less than that of the sleeve 4, so that the outer sleeve 1 can slide on the outer surface of the sleeve 4. The distance between the two ends of the outer sleeve 1 and the sleeve 4 can be adjusted according to actual needs. Preferably, the length of the outer sleeve 1 is 185 mm, the inner diameter is 12 mm, the height of the semicircular ring pressing block 2 is 113 mm, the inner diameter of the semicircular ring pressing block 2 is 36 mm, and the outer diameter is 80 mm.

[0032] The fixing parts, limiting parts and disassembly parts are all made of metal.

[0033] Working process:

[0034] When removing the glue roller nut, extend the sleeve 4 into the glue roller rubber frame, and the limit ring 6 and the limit column 7 engage with the glue roller nut to fix it; extend the long hexagonal wrench 8 along the sleeve 4 into the middle of the limit ring 6 until it engages with the center screw of the glue roller nut, grab the first handle 9 to fix the screw through the long hexagonal wrench 8, and then rotate the limit ring 6 through the second handle 5; you can also rotate the first handle 9 and the second handle 5 at the same time to make the screw and the glue roller nut rotate relative to each other, and then remove the glue roller nut.

[0035] When changing the blade of the cigarette making machine, the disassembly part is taken out from the limit part, and then the semi-circular ring clamping block 2 is pressed against the gasket corresponding to the blade nut to be disassembled, and the sleeve 4 is slid in the outer sleeve 1 until the hexagonal wrench 10 is engaged with the blade nut to be disassembled, and then the third handle 3 is used to apply force to make the semi-circular ring clamping block 2 press the gasket, and the second handle 5 is used to rotate the hexagonal wrench 10 to remove the blade nut.

[0036] The utility model is easy to carry and has a simple and effective structure, and can accurately and quickly disassemble the glue coating roller nut and the blade nut.
