[0046] In some embodiments, the waste film roll cutting device further comprises a pre-pressing assembly 6. The pre-pressing assembly 6 comprises a pre-pressing block 62 and an elastic member 61. One end of the elastic member 61 is fixedly arranged on the side of the plate 31 close to the limiting groove 22, and the other end of the elastic member 61 is connected with the pre-pressing block 62. The distance from the pre-pressing block 62 to the plate 31 is greater than the distance from the cutting edge of the cutting knife 32 to the plate 31, and the pre-pressing block 62 can press against the fixed waste film roll 100. Specifically, a set of pre-pressing assemblies 6 is arranged on each side of the cutting knife 32. During the downward movement of the plate 31 driven by the driving assembly 5, the pre-pressing block 62 first presses against the waste film roll 100. During the continuous downward movement of the plate 31, the cutting knife 32 starts to cut the waste film roll 100. At this time, the elastic member 61 is compressed, and the pre-pressing block 62 tightly presses against the waste film roll 100 under the action of the elastic restoring force, so as to prevent the waste film roll 100 from rotating, thereby ensuring the smooth cutting work. In order to ensure that the pre-pressing block 62 can tightly fit the waste film roll 100, the lower end surface of the pre-pressing block 62 is designed as an arc surface, so that the pre-pressing block 62 can effectively fit the waste film roll 100, thereby tightly pressing the waste film roll 100.
