Description

Technical Field

[0001] The utility model belongs to the technical field of slitting machines, and in particular relates to an adjustable slitting machine for film processing. Background Art

[0002] Film printing and slitting are inseparable. Cutting the film material after printing can avoid damage to the film during the printing process. Cutting after printing can also customize the size of the product according to customer needs.

[0003] After printing, film slitting requires processing according to production requirements. Slitting machines are essential equipment for film processing, primarily used to cut large rolls of film material into strips of the desired width. Traditional slitters are mostly fixed-width and lack flexibility. Even with adjustable slitters, the blades still need to be manually changed to meet varying cutting requirements.

[0004] The existing Chinese patent publication number CN221641124U discloses a thermal paper slitting machine that is easy to adjust the slitting width, including a slitting mechanism, a squeezing mechanism fixedly mounted on the top of the slitting mechanism, and the squeezing mechanism including a bracket. In the utility model, through the cooperation of the slitting mechanism and the squeezing mechanism, when the slitting machine is in operation, after the second motor is started, it will drive the cutter to rise and cut the thermal paper above. When the cutting width needs to be adjusted, only a screw needs to be rotated to pull out or fix the cutter inserted into the placement slot. By changing the number of cutters, the cutting width can be freely adjusted to adapt to different production needs, which increases the practicality of the device, eliminates the need to purchase different slitting machines, effectively reduces production costs, and also eliminates the need to replace equipment during the thermal paper production process, thereby improving work efficiency.

[0005] In summary, in order to adapt to different production needs, the adjustable slitting machine in the existing technology needs to manually extract or fix different cutters when adjusting the cutting width. Such operation has low production efficiency, and frequent extraction of fixed cutters will accelerate the wear of the carrier. Utility Model Content
