【Highly Efficient and Stable】：This semi-automatic labeling machine operates semi-automatically with a high-quality motor, capable of labeling 20-50 labels per minute (depending on label type), significantly higher than manual labeling. It supports up to 50 labels per minute for non-positioning labels, with a labeling accuracy of ±1mm, easily handling various round bottles such as condiment bottles, beverage bottles, and wine bottles. 【Precise Positioning】：Equipped with an intelligent fiber optic sensor (optical eye) and two-in-one coding labeling technology, it accurately detects label position, avoiding missed labels, misalignments, and label waste. Note: This machine is not suitable for transparent, gold, or silver labels and is suitable for perfectly cylindrical bottles (no dents or protrusions on the bottle body or cap). 【Robust and Durable】：The round bottle labeling machine is made of high-quality pure aluminum alloy, integrally molded, rust-proof, and wear-resistant. The thickened swing arm is not easily deformed, and the rollers are adjustable up and down to adapt to different bottle shapes, ensuring long-term stable use. 【Easy Label Change】：Upgraded manual rotation adjustment setting allows for quick label roll changes without a wrench. With its waste paper collection wheel and automatic bottom paper feeding function, this labeling machine is time-saving, labor-saving, and easy to maintain, significantly improving changeover efficiency for multi-variety, small-batch production. 【It has a wide range of applications】：Our labeling machine is suitable for round bottles (PET, plastic, glass, metal, etc.), supporting bottle diameters of 15–130mm (approximately 0.59–5.1 inches), label roll widths of 30–130mm, and core diameters of 75mm (outer diameter <260mm). It is widely used in the food, beverage, and tea industries, providing flat, bubble-free, wrinkle-free, and edge-free labeling. Note: This product is not suitable for transparent labels.
