[0044] The blown film is deflected by multiple groups of the reversing rollers 502 and wound and collected on the surface of the collecting roller 504. The second motor 506 drives the quick-release outer shell 5051 to rotate. The quick-release outer shell 5051 drives the guide plate 5054 to rotate. The guide plate 5054 drives the fixed outer shell 5053 to rotate. The rotation of the fixed outer shell 5053 drives the collecting roller 504 to rotate. The rotation of the collecting roller 504 winds the blown film product. During disassembly and assembly, manually slide the sliding seat 5056. The sliding seat 5056 drives the limiting shaft 5057 to leave the inner wall of the limiting hole 5052, so that the fixed outer shell 5053 and the guide plate 5054 slide on the inner wall of the quick-release outer shell 5051, so that the collecting roller 504 is disengaged from the side of the quick-release outer shell 5051, thus realizing the quick disassembly of the guide plate 5054. The collection and quick disassembly of the product are realized.
