For the ease of stirring, described slice device is located at the following rear of blanket roller.

Described cross-brace sliver transvers section is " ∏ " shape, the lower end of its vertical edge is welded on the supporting plate, on horizontal sides, open described bar hole, after described bolt is worn this through hole of crossing bar hole and level board from lower to upper, by nut check, above structure is being convenient to adjust under the prerequisite of level board position, and energy firm fixation, accurate position level plate are so that obtain the satisfactory film of width.

Described slice cutter is discoid, and the edge of its card has blade, and the center line of slice cutter is parallel with the center line of described blanket roller.

Compare with the strip structure of traditional slice cutter, this structure has effectively been improved stressed distribution situation, can effectively avoid the flexural deformation of slice cutter, and the blade that prevents the slice cutter breaks away from the blanket roller barrel, thereby guarantee that further cutting glue, slice carries out smoothly, has significantly improved reliability of the present utility model.

Beneficial effect: the utility model is skillfully constructed, simple in structure, under the effect of corresponding cylinder, can compensate the wear extent that each goes out knife-blade automatically, and they are close on the blanket roller barrel, and then guarantee that cutting glue, slice carries out smoothly.
