Product Introduction：

The semi-automatic front-and-back roll-on labeling machine is a packaging device that integrates semi-automatic feeding with automatic labeling. Utilizing the “roll-on” process, it is specifically designed for precision labeling of products with flat, curved, concave, and irregular surfaces, and is particularly suitable for scenarios requiring simultaneous labeling on both the front and back or the top and bottom of products.

This equipment strikes a balance between investment costs and production efficiency. It ensures labeling accuracy through automated mechanisms while retaining the flexibility of manual product placement, making it highly suitable for small-to-medium batch and multi-variety production needs. It is widely used in industries such as electronics, personal care, pharmaceuticals, and food.

Features：

High-Precision Labeling: Utilizing a PLC (Programmable Logic Controller) and stepper motors to drive label feeding ensures precise labeling positioning. Mainstream models achieve a stable labeling accuracy of ±0.5 mm, meeting the stringent requirements of industries such as electronics and pharmaceuticals.

Powerful Features and Wide Range of Applications: By replacing different label application mechanisms or fixtures, the machine can easily handle labeling tasks on flat, curved, concave, and even irregular surfaces. Application examples include flat cosmetic bottles, electronic product casings, square packaging boxes, wine bottles, and various types of bottle caps.

User-Friendly Operation and Simple Maintenance: All operations—including label peeling, feeding, suction, application, and sealing—are fully automated. Operators are only responsible for loading and unloading. The PLC control system typically features a human-machine interface (HMI) with clear parameter settings and simple adjustments.

High-quality labeling: The “roll-on” method effectively removes air between the label and the product, ensuring a tight, flat, and bubble-free bond—particularly suitable for transparent labels where aesthetic appeal is critical.

Robust construction and long service life: The main body is primarily constructed from high-strength aluminum alloy and 304 stainless steel. Electrical and pneumatic systems are physically separated, which not only meets GMP and other workshop hygiene requirements but also significantly extends the equipment’s lifespan.
