[0028] Specifically, Figures 2 to 4 As shown, the die-cutting component 2 includes an arc cutter 201, which is connected to a driving shaft 202, and both ends of the driving shaft 202 are rotatably connected to first bearings 203. The bearing component 3 includes a driven shaft 301, which is connected to a fixed cylinder 302, and the fixed cylinder 302 is rotatably connected to a second bearing 303. The arc cutter 201 and the second bearing 303 are used in correspondence. The driving component 1 includes a motor 101, which is connected to a reducer 102, which is connected to a driving wheel 103, which is connected to a belt 104, which is connected to a driven wheel 105, and which is connected to the driving shaft 202.

[0029] The arc cutter 201 includes an upper semicircular block 2011 and a lower semicircular block 2012 . A blade 2013 is provided on the upper semicircular block 2011 . The two semicircular blocks are designed to be detachably mounted on the driving shaft 202 .

[0030] The die-cutting principle of the arc rolling cutter mechanism is that after the motor 101 is started and decelerated by the reducer 102 while increasing the output torque, it drives the driving wheel 103 to rotate, the driving wheel 103 drives the belt 104 and the driven wheel 105 to rotate synchronously, the driven wheel 105 drives the driving shaft 202 to rotate, the driving shaft 202 drives the arc cutter 201 to rotate, the arc cutter 201 drives the second bearing 303 to rotate inward, and the tissue packaging film is rolled in for die-cutting, wherein the second bearing 303 not only has high hardness, but also serves the purpose of being easy to replace.

[0031] like Figures 5 and 6As shown, the support assembly 4 includes a support plate 401, the support plate 401 is provided with a through hole 4011, the first bearing 203 is arranged in the through hole 4011, a recess 4012 is arranged above the through hole 4011, and the recess 4012 is provided with an adjustment assembly 402, the adjustment assembly 402 includes an outer cylinder 4021, the outer cylinder 4021 is threadedly connected to the plate 4022, a bottom column 4023 is movably inserted in the outer cylinder 4021, the bottom column 4023 is sleeved with a pressure spring 4024, the lower end of the bottom column 4023 is connected to a mounting seat 4025, the pressure spring 4024 is arranged between the plate 4022 and the mounting seat 4025, a plurality of support springs 4026 are arranged below the mounting seat 4025, the driven shaft 301 is connected to the mounting seat 4025, a plurality of first mounting positions 4027 are arranged at the lower end of the mounting seat 4025, and a plurality of first mounting positions 4027 are arranged at the upper end of the recess 4012.

The provision of a pressure spring 4024 is conducive to the second bearing 303 being able to maintain adhesion to the tissue packaging film, and also enables the second bearing 303 to maintain a resisting force on the arc cutter 201, so that the rotation of the arc cutter 201 will drive the second bearing 303 to rotate as well, matching the transmission of the tissue packaging film, and also enhancing the stability of die-cutting, which can well protect the blade 2013 and ensure the quality of the incision. The support spring 4026 ultimately causes the second bearing 303 to lift upward, reduces the pressing force of the second bearing 303 on the arc cutter 201, and avoids excessive downward pressure on the second bearing 303, which can easily cause wear or even damage to the arc cutter 201.
