Description

Technical Field

[0001] This utility model relates to the field of film slitting and winding technology, specifically to a heat shrink film slitting and winding assembly that is easy to adjust. Background Technology

[0002] Heat shrink film is a commonly used material in the packaging industry and is widely used in food, home appliances, logistics and other industries. In its production process, the wide master film needs to be cut into finished films of different widths through a slitting and winding assembly, and the winding is completed simultaneously. The slitting accuracy and winding stability directly determine the product quality of heat shrink film.

[0003] However, current mainstream heat shrink film slitting and winding assemblies have significant shortcomings in terms of cutter spacing adjustment, which restricts production efficiency and adaptability. The specific pain points are as follows: The adjustment operation is cumbersome and time-consuming: Most existing assemblies adopt a "single-blade independent fixing" structure, where the cutter is directly locked to the slitting shaft by bolts. When adjusting the spacing, it is necessary to loosen the bolts one by one, manually move the cutter to the target position, and then tighten the bolts again. For multi-blade slitting scenarios, it is necessary to repeatedly calibrate the position of each cutter, which seriously affects the production changeover efficiency. To address this, we propose a heat shrink film slitting and winding assembly that is easy to adjust. Utility Model Content

This assembly offers the advantage of easy adjustment and solves the significant defects in cutter spacing adjustment found in current mainstream heat shrink film slitting and winding assemblies, which restrict production efficiency and adaptability. Specific pain points are as follows: Cumbersome and time-consuming adjustment operation: Existing assemblies mostly adopt a "single-blade independent fixing" structure, where the cutter is directly locked to the slitting shaft by bolts. Adjusting the spacing requires loosening each bolt individually, manually moving the cutter to the target position, and then retightening the bolts. For multi-blade slitting scenarios, the position of each cutter needs to be repeatedly calibrated, severely impacting production changeover efficiency.
