[0074] In some of these examples, see Figure 8 、 Figure 9 As shown, the cache device 400 includes a cache fixing seat 410, a cache toggle 420, a rotating component 430, and a cache driving component 440. The fixing seat is used to be installed on the machine 800, and the rotating component 430 can be rotatably connected to the fixing seat. The cache toggle 420 is connected to the first end of the rotating component 430. When installed, the cache toggle 420 is located above the continuous webbing 20. The cache driving component 440 is connected to the second end of the rotating component 430. The cache driving component 440 is used to drive the rotating component 430 to rotate to drive the first end of the rotating component 430 to rise or fall. When the first end falls, the cache toggle 420 can drive part of the continuous webbing 20 to fall to achieve caching. Among them, the cache driving component 440 is electrically connected to the control device 900.

[0075] In some embodiments, the cache toggle member 420 is a rod-shaped structure, and the cache toggle member 420 is in a horizontal state when installed.

[0076] In some of these examples, see Figure 10- Figure 12 As shown, the first end portion of the rotating component 430 is bent. When the buffer fixing seat 410 is installed on the machine 800 , the bending direction of the first end portion is upward, so that the first end portion of the rotating component 430 is warped upward.

[0077] In some embodiments, the cache device 400 further includes a cache rotation shaft 450 . The rotation component 430 is connected to the cache fixing seat 410 via the cache rotation shaft 450 , and the rotation component 430 is rotatably connected to the cache rotation shaft 450 .

[0078] In some embodiments, the center of the rotation axis 450 of the rotation member 430 is closer to the second end.

[0079] In some embodiments, the length of the cache toggle 420 is 2 cm-8 cm, and the length of the cache toggle 420 is greater than the transverse width of the continuous webbing 20 .

[0080] In some embodiments, the cache device 400 further includes a cache mounting base 460 . The cache mounting base 460 is used to be mounted on the machine 800 , and the cache driving component 440 is mounted on the cache mounting base 460 .

[0081] In some of these examples, see Figure 11 As shown, a buffer guide 470 and a buffer slide 480 are provided on the buffer mounting seat 460. The buffer guide 470 is mounted on the buffer mounting seat 460. The buffer slide 480 is slidably connected to the buffer guide 470. The first end of the rotating component 430 is connected to the buffer slide 480.

[0082] In some of these examples, see Figure 10 As shown, the cache guide 470 extends in a vertical direction relative to the cache mounting seat 460. When the cache device 400 is installed on the machine 800, the cache guide 470 extends in the vertical direction. The cache device 400 also includes a cache connecting rod 490. One end of the cache connecting rod 490 can be rotatably connected to the second end of the rotating part 430, and the other end of the cache connecting rod 490 can be rotatably connected to the cache sliding member 480.

[0083] The above-mentioned buffer device 400 can realize the relaxation of the continuous webbing 20 from tension to relaxation before the continuous webbing 20 is cut, thereby solving the rebound problem of the continuous webbing 20 in the prior art when the continuous webbing 20 is cut. In operation, when the continuous webbing 20 is pulled forward, the continuous webbing 20 drives the buffer actuator 420 to rise to a horizontal state. When the continuous webbing 20 needs to be buffered, the buffer driving member 440 drives the second end of the rotating member 430 to rise, at this time, the first end is driven to descend by the rotating member 430 and the buffer actuator 420 is pressed down, the buffer actuator 420 can drive part of the continuous webbing 20 to descend to realize buffering, the length of the end of the continuous webbing 20 passively pulled up under the pressing action of the buffer actuator 420 is the length of the buffered part, at this time, the continuous webbing 20 is in a tension state under the action of the buffer actuator 420.
