Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a film slitting machine. Background Art

[0002] Film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by the deposition of atoms, molecules or ions on the surface of a substrate. The width of plastic film is relatively wide when it is produced, but in the finished product stage, different widths of film are required according to different packaging requirements, so the wide plastic film needs to be cut into finished products of different widths.

[0003] After searching the Chinese patent with publication number CN218614451U, a film slitting machine is disclosed. The annular sleeve is pushed to move on the top slitting roller, moved to the appropriate position, and after measuring the size, the handle is rotated in the opposite direction again, which can drive multiple strip positioning strips to be stuck in the corresponding strip positioning grooves, so that the position of the convex adjustment block after movement can be fixed, and the position of the slitting pressure wheel can be fixed, so as to facilitate the rapid adjustment of the position of the slitting pressure wheel. Compared with the traditional disassembly of multiple bolts, it is more convenient and quick, reduces the adjustment time, and avoids the disassembly of multiple bolts back and forth, which causes thread slippage.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The cutting size is adjusted by adjusting the position of the slitting wheel, but a single slitting wheel can only divide the film into two parts at most. When multiple slitting is required, repeated operations are required, and there is no limiting structure, the film is easy to deflect, and the spacing adjustment operation is still not simple enough, which reduces the use efficiency of the film slitting machine.
