In cultural creative gifts, garment accessories and food packaging, demand keeps growing for top-surface labeling of flat materials such as cards, hang tags and unformed cartons. However, many glossy or laminated thin materials are easily scratched or scuffed by roller friction or hard contact during conventional sheet feeding and conveying, which seriously affects appearance yield. Manual sheet-by-sheet loading is also slow and prone to missing or empty labels. Balancing scratch protection with efficiency is a pain point in line upgrades.

1. Pain points in labeling scratch-prone flat materials

Conventional labelers handling thin products such as cards and plastic bags mostly use friction sheet feeding. Although inexpensive, this produces considerable hard friction between the material surface and the separating belts and conveyor belts at high speed, leaving scratches on laminated or glossy surfaces. For flat materials of uneven thickness or soft texture, friction feeding also causes jams and multiple sheets feeding at once, which in turn causes label shift or missing labels.

To address this industry problem, Wanzhi Automation developed the WZ-123 vacuum pick-and-place sheet-feeder labeling machine. Designed for scratch-prone flat materials, it uses an innovative vacuum negative-pressure pick-and-place feeding mechanism that physically eliminates hard friction contact, providing reliable automation for volume labeling of products with high appearance requirements.

2. The WZ-123 vacuum pick-and-place sheet-feeder labeling machine in technical detail

As a professional automatic labeling machine, the WZ-123 is deeply optimized for scratch protection and stability. Its core technical advantages are:

  • Vacuum pick-up scratch protection:Vacuum suction cups separate and convey stacked material one sheet at a time, with no roller friction or squeezing at any point, fully protecting the appearance of glossy and laminated products.
  • Automatic loading and precise sensing:A full stack of material is loaded at once, photoelectric sensing detects material position in real time and precisely triggers dispensing and labeling. Labeling error is held within ±1mm, effectively preventing missing and empty labels.
  • Broad material compatibility:The machine handles flat products from 0.5-5mm thick and 80-400mm long, with conveyor belt speed adjustable between 20-35M/min, easily matching different production paces.
  • Modular expandability:As a multifunction labeling machine, the WZ-123 can be fitted with multi-head modules, a coding unit or an inline printer as needed, completing sheet-fed labeling and printing of traceability information such as production dates and barcodes in one process.

The visual touch screen allows parameters to be stored and recalled, changeover is convenient, and long continuous production runs are supported, greatly improving the overall efficiency of the line.

3. Selection essentials and application advice

When introducing the WZ-123, configure it to suit your own line:

  • Assess material properties:If the product surface is glossy, laminated or scratch-prone, vacuum pick-and-place feeding is essential; also confirm that the material falls within the 0.5-5mm thickness and 80-400mm length range.
  • Optional function modules:If the product needs labels on several surfaces, specify multi-head modules; if batch numbers or QR codes must be printed at the same time, add a coding unit or thermal transfer printer.
  • Typical applications:The machine is widely used for card labeling in cultural creative gifts, hang tag labeling in garment accessories, carton and plastic bag labeling in food packaging, and volume production of all kinds of thin printed paper products.

With the right selection and configuration, companies can lower labor costs, improve appearance yield and standardize and automate the labeling process.

FAQ

1. Will the WZ-123 damage the material surface?

No. The machine uses a vacuum negative-pressure pick-and-place mechanism: suction cups separate and convey the material, with no hard friction or squeezing at any point, effectively protecting glossy, laminated and other scratch-prone surfaces.

2. How thick a flat material can the machine handle?

The WZ-123 has broad material compatibility, handling flat products from 0.5mm to 5mm thick and 80mm to 400mm long, such as cards, hang tags and unformed cartons.

3. Can production dates or barcodes be printed at the same time as labeling?

Yes. The modular design allows a coding unit or inline printer to be added, so traceability information is printed during sheet-fed labeling.
