Description

Technical Field

[0001] The utility model relates to the field of pelletizing machinery, in particular to a device for preventing material leakage of a pelletizing machine. Background Art

[0002] In the production process of foam plastics and polymer particles, a pelletizer 1 is required to cut the material strips 2 into finished particles for bagging, such as Figure 1 As shown, the basic working principle of the pelletizer 1 is that the upstream roller group 3 sends out the material strips 2, and the downstream knife roller 4 rotates to cut the sent material strips 2 into particles. Combining production practice and usage experience, it is known that the distance between the feed roller group 3 and the knife roller 4 in the existing pelletizer 1 is usually 15cm-25cm, and there is a lack of downward pressure limit above the material strips 2 between the feed roller group 3 and the knife roller 4. When the knife roller 4 contacts the material strips 2, the brittle material strips 2 are prone to breakage, resulting in long particles and material leakage, and there is a certain room for improvement.
