Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleeve labeling machines face challenges in accurately conveying and wrapping shrink film around bottles or cans of varying thickness without causing wrinkles, as existing mechanisms struggle to adjust to changes in film thickness.
Innovation Solution
A sleeve labeling machine with a shrink film synchronous transmission device featuring label feeding and pulling rollers at the upper and lower cutter device, equipped with a linkage gear module and support frame, allowing for adjustable distance between feeding and pulling pulleys to ensure synchronous operation and prevent wrinkles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three feeding roller sets are used at upper, middle and lower center guide column to guide shrink film down, then the mechanism can accommodate different can or bottle diameters through adjustment, but the system becomes complex and cannot reliably handle shrink film of varying thickness without causing wrinkles
Solution Approach 1:
The patent divides the shrink film conveyance function into two separate roller sets: an upper feeding roller set and a lower pulling roller set. This segmentation allows each roller set to perform a specific function (feeding and pulling) rather than relying on a complex three-level system, thereby reducing overall system complexity while maintaining adaptability through adjustable roller positions and synchronous operation capability.
Solution Approach 2:
The patent implements dynamic adjustment capability where the distance between the upper feeding roller set and lower pulling roller set can be adjusted to accommodate different shrink film thicknesses. The synchronous operation of the roller sets allows the system to adapt to varying material properties, providing the necessary flexibility without requiring a fixed complex structure.
2Ease of operation
If feeding rollers are adjusted to match center guide column diameter, then the mechanism can show different setting angles for different cans or bottles, but accurate conveyance of shrink film with changing thickness remains uncertain
Solution Approach 1:
The patent provides dynamic adjustability where the distance between upper feeding rollers and lower pulling rollers can be modified to accommodate different shrink film thicknesses. This dynamic configuration ensures reliable conveyance while maintaining ease of operation for different container types through adjustable setting angles.
Solution Approach 2:
The patent enables parameter changes in the conveyance system by allowing adjustment of the vertical distance between roller sets and their horizontal positioning. These parameter adjustments ensure accurate conveyance of shrink film regardless of thickness variations, while maintaining operational ease for different container geometries.
3Speed
If shrink film is conveyed down center column with feeding rollers, then the film can be guided to move down, but wrinkles are produced that hinder conveyance and prevent accurate sleeve labeling
Solution Approach 1:
The patent segments the conveyance function into feeding (upper rollers) and pulling (lower rollers) operations. This segmentation allows controlled movement of shrink film at optimal speeds while preventing wrinkle formation through coordinated synchronous operation, thereby maintaining both conveyance speed and labeling precision.
Solution Approach 2:
The patent ensures continuous useful action through synchronous operation of upper feeding rollers and lower pulling rollers. This continuous coordinated action prevents interruptions and wrinkle formation during shrink film conveyance, maintaining both high-speed operation and precise sleeve labeling quality.

AI summary
A sleeve labeling machine includes a center column, a transmission device, and a cutter device. The center column can unfold the shrink film, and a transmission device will carry the shrink film and let the shrink film sleeve on the center column. Then, the cutter device will cut the shrink film, and the transmission device will keep pulling each cut shrink film to cover the surface of a bottle or a can. Finally, the transmission device will convoy bottles or cans to the next device, and let the shrink film combine with the bottle or the can to complete the bottle or can sleeve labeling process.
