Line upgrades for cultural-creative products and garment accessories: how to feed and label scratch-prone sheet materials without scratching them – WZ-123 application analysis

In recent years, the cultural-creative gift and garment accessory industries have imposed increasingly strict requirements on packaging appearance. However, many scratch-prone sheet materials, such as laminated cards and high-gloss hang tags, are often scratched during automated packaging because of conventional mechanical friction. To address this industry pain point, Wanzhi Automation has recently delivered WZ-123 vacuum pick-and-place sheet-feeder labeling machines to several well-known packaging companies for production, providing a reliable solution for batch production of products with high appearance requirements.

Limitations of conventional friction feeding and the need for non-contact separation

On conventional packaging lines, standard labeling machines usually separate and convey materials by friction from rollers or belts. This hard contact easily causes irreversible scratches and wear on smooth, laminated, or high-gloss coated sheet materials. In addition, uneven friction makes thin materials prone to double feeds, jams, and labeling wrinkles during high-speed feeding. This increases defect rates and leads to frequent downtime for cleaning, seriously affecting throughput. The industry has therefore reached a consensus to move away from conventional friction feeding toward non-contact separation, and vacuum pick-and-place sheet feeding emerged as the answer.

WZ-123 vacuum pick-and-place sheet-feeder labeling machine: technology and production deployment

To solve these problems, Wanzhi Automation developed the WZ-123 vacuum pick-and-place sheet-feeder labeling machine. Its core innovation is a vacuum negative-pressure pick-and-place feeding mechanism that uses vacuum suction cups to separate and convey stacked materials one sheet at a time, with no hard friction contact at any point, fundamentally eliminating surface scratches and wear. In terms of technical specifications, the model is WZ-123, and labeling accuracy is stable with error strictly controlled within ±1mm, effectively preventing missed labels and misalignment. The conveyor belt speed is steplessly adjustable from 20-35M/min to suit different companies’ production cycles. A photoelectric sensing system detects material position in real time and triggers label dispensing precisely, ensuring efficient and stable labeling.

Selection considerations and practical line recommendations

When introducing this type of equipment, companies should consider the following selection and operational points:

• Confirming material compatibility: Confirm that material dimensions and thickness are within the machine’s compatible range. The WZ-123 handles sheet products from 0.5-5mm thick and 80-400mm long.
• Modular functional expansion: For lines that require traceability, we recommend adding an inline coding machine or printer module so that labeling and date and barcode printing are integrated.
• Parameter presets and line changeover: Wanzhi recommends that companies use the touch screen’s parameter storage function before production starts to preset setup parameters for each product, greatly shortening changeover time and improving continuous production efficiency.

FAQ

With slightly porous materials, will vacuum pick-and-place feeding fail to hold or drop the material?

No. The WZ-123 is equipped with a high-vacuum generator and custom suction cups that automatically adjust holding force according to the material’s porosity, ensuring stable single-sheet pickup and separation.

If the line needs to switch between hang tags or cards of different sizes, is setup cumbersome?

The machine uses a visual touch screen interface with parameter recipe storage. To change products, simply recall the corresponding program and make minor mechanical limit adjustments, and production resumes quickly.

Can the machine apply multiple labels or print information at the same time?

Yes. The machine offers modular expansion and can be equipped with multi-head modules, a coding machine, or an inline printer as needed, completing multi-head labeling and traceability printing in one pass.
