Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to a novel roll film slitting mechanism for a multi-row packaging machine. Background Technology

[0002] In the current roll film processing industry, traditional slitting equipment has several significant shortcomings. First, the slitting blades of traditional roll film slitting mechanisms cannot be lifted as a whole, causing considerable difficulty for operators during film threading, wasting time and effort, and reducing production efficiency. Second, when the slitting blades wear out and need replacement, due to unreasonable structural design, maintenance personnel are prone to accidentally bumping the blades during disassembly and installation, damaging the new blades and increasing maintenance costs. Furthermore, during equipment transportation, because the slitting blades cannot be lifted and secured as a whole, bumps and vibrations during transport often damage the blades, affecting the equipment's lifespan and cutting quality.

The electric cylinder 400 stops moving after reaching its stroke limit. The entire slitting blade assembly 100 is then lifted.

[0037] At this point, the membrane slitting blade 1300 can be inserted, maintained, or replaced. After completion, the guide rod of the electric cylinder 400 retracts in the same manner. Once it retracts to its travel limit and the slotted photoelectric switch 700 illuminates, it indicates that the membrane slitting blade 1300 is properly pressed; otherwise, insufficient pressure will prevent the membrane slitting blade 1300 from cutting the film roll. The slotted photoelectric switch 700 ensures that the membrane slitting blade 1300 is properly pressed after each insertion or maintenance, preventing the membrane slitting blade 1300 from applying insufficient pressure and failing to cut the film roll.

[0038] This utility model eliminates the drawbacks of the entire slitting mechanism and improves the efficiency and convenience of the equipment by adding a slitting blade assembly that can be lifted as a whole and using it in conjunction with a photoelectric switch.
