The spring 452 is sleeved on the bolt 451 between the chassis 44 and the positioning plate 46. When the end face of the incoming product is not a vertical surface, the positioning plate 46 automatically levels the end face of the product through the floating assembly 45, fits tightly with the end face of the product, and positions the product properly.

[0035] When the fully enclosed biochemical medical film cutting machine of the present invention is working, the lifting door 6 is opened, the protective door 272 of the protective assembly 27 is lowered, the worker places the product to be cut on the V-shaped seat of the feeding mechanism 3, and the pressing cylinder 35 drives the pressing plate 36 to move down and press the product to complete the loading. The lifting door 6 is closed, the protective door 272 is raised, and the feeding mechanism 3 drives the product to move toward the positioning mechanism 4 until the end face of the product is against the positioning plate 46 to position the product. The heating of the heating rod 47 can preheat the product to be cut in preparation for subsequent cutting. The heating module 26 preheats the cutting knife 25. After reaching the cutting temperature, the cutting power source 22 drives the cutting knife 25 to move down and cut the product. The cut product slides from the guide chute 9 to the finished product box 10, and the cutting knife 25 moves up.
