Specifically, the dust collecting mechanism 70 includes a plurality of dust collecting trays 71 connected in series, and the dust collecting trays 71 are disposed obliquely so as to guide the collected dust downward. From this, the material area is cut into many small strips, many via cutting the mechanism the small strip moves towards winding mechanism, when the dust that carries on the small strip drops, just can fall into collection dirt dish 71.

Referring to fig. 1 or 2, in an embodiment, the splitting machine includes two sets of winding mechanisms, and the two sets of winding mechanisms are disposed along a vertical direction, so that a dust collecting mechanism 70 is disposed between the two sets of winding mechanisms to prevent dust entering the small strips of the upper winding mechanism from interfering with the small strips below.

Further, a waste bin may be provided below the dust collection tray 71 to better collect dust.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
