[0023] A transparent observation window 111 is provided on the cylinder 1 to observe the internal material conditions.

[0024] In this embodiment, three sets of side cutting blades 17 are fixedly installed inside the chamber 15. They can be set at the entrance of the chamber 15. During the material entry process, they cut the side of the packaging film. After the material comes into contact with the bottom cutting blade 18, the ring motion drive assembly 14 drives the bottom cutting blade 18 to move in an arc to cut the bottom of the packaging film. After the cutting is completed, the material can be taken out. At this time, there are multiple cuts on the packaging film, and the microbial petri dishes can be easily taken out.

[0025] In this embodiment, the ring motion drive component 14 can be an electric ring guide rail or a manually driven one.

[0026] Example 2:

[0027] Unlike in Embodiment 1, in this embodiment, the side cutting blade 17 is designed to move up and down, enabling multiple up-and-down cutting movements. Specifically, as shown... Figure 1 , Figure 2 The side cutting blade 17 is connected to the vertical drive assembly 13. The vertical drive assembly 13 is used to drive the side cutting blade 17 to move in the height direction and cut the packaging film along the height direction. A vertical track 114 is provided in the chamber 15. The vertical drive assembly 13 includes a sliding frame 133 and an operating frame 131. The number of sliding frames 133 is the same as the number of side cutting blades 17. The sliding frames 133 are installed in the vertical track 114.
