Automatic Bottom Labeling Machine

It is suitable for applying barcode labels, price labels, production information labels, traceability labels, anti-counterfeit labels, or instruction labels to the underside of packaging boxes. Compared with manual turning and labeling, this machine reduces operation steps, improves labeling efficiency, and keeps label placement consistent and neat. During operation, products enter the labeling area through the conveyor.

Once the photoelectric detection system identifies the product, the signal is sent to the control system, and the bottom labeling mechanism automatically dispenses and applies the label. After the label is attached to the bottom surface, the pressing roller smooths it firmly onto the product, helping reduce label deviation, edge lifting, bubbles, wrinkles, and missed labeling.

The entire process is completed continuously, allowing labeled products to move directly to the next packaging, inspection, or collection stage. The automatic bottom labeling machine uses a PLC control system and touch screen interface, making parameter setting clear and convenient. Operators can adjust the machine according to different box sizes, label specifications, and production speeds.

The automatic bottom labeling machine supports operation status prompts, fault display, label management, and product counting, making on-site production management easier. Its stable stepper-driven label feeding system, wear-resistant driving roller, and self-adjusting pressure roller help reduce label slipping, label deviation, and unstable dispensing, ensuring consistent accuracy during long-term operation. The machine is suitable for products with a height range of 20–300mm, label heights from 10–150mm, and label lengths from 15–300mm.

Customized specifications are available according to customer samples. The labeling speed can be adjusted according to product size, label length, feeding speed, and upstream or downstream line requirements, with a capacity of up to 30–100 pieces per minute. With its compact structure, it can be used as a stand-alone machine or integrated into an existing packaging line for automation upgrades.

Optional functions such as a thermal coding printer, inkjet printer, transparent label sensor, and QR code or barcode reader can be added according to production needs. These options allow production dates, expiry dates, batch numbers, supervision codes, and traceability codes to be printed or read during bottom labeling, helping reduce downstream packaging steps and improve product information management.

The automatic bottom labeling machine is widely used in food and beverage, grain and oil, pharmaceutical, health product, daily chemical, chemical, electronics, stationery, plastic box, paper box, gift box, card product, and flat packaging industries.

For manufacturers looking to improve bottom labeling efficiency, maintain consistent label placement, reduce manual labeling errors, and enhance packaging standardization, the automatic bottom labeling machine provides a stable, practical, and easy-to-integrate automatic labeling solution.
