Automatic Double Side Labeling Machine

The machine adopts a double-side labeling structure. After products enter the conveyor, the bottle separation mechanism automatically spaces each container, while the alignment mechanism adjusts the product into a stable position. The top pressing and guiding devices keep the bottle upright during conveying.

When the product reaches the labeling area, the detection system identifies its position and sends a signal to the control system. The two labeling heads then dispense and apply the front and back labels according to preset parameters, helping keep both labels aligned and consistent. After labeling, the rolling mechanism presses the labels firmly onto the product surface, reducing bubbles, wrinkles, skewed labels, and edge lifting.

The main advantages of the automatic double side labeling machine are strong compatibility, stable labeling performance, and convenient adjustment.

It is suitable not only for standard square and flat bottles, but can also be adapted for round bottles, irregular containers, adjacent right-angle surface labeling, or multiple-side labeling requirements. The double-side rigid guiding conveyor helps keep products centered and reduces the difficulty of manual feeding or line integration. With PLC control and a touch screen interface, operators can store multiple sets of product parameters and quickly switch between different bottle types and label specifications.

The automatic double side labeling machine is suitable for products with a diameter range of approximately 25–120mm and a height range of 40–400mm. It supports label heights from 10–150mm and label lengths from 10–300mm, with customized specifications available according to sample products. The labeling speed can be adjusted according to product size, label size, and feeding speed, with a maximum speed of 60–150 bottles per minute.

The detection and label dispensing system supports no-bottle-no-label operation, helping reduce label waste. Alarm indication and emergency stop protection also make daily production supervision and operation safer and more convenient.

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 identified during the labeling process.

The automatic double side labeling machine is widely used in daily chemical, household chemical, food and beverage, pharmaceutical, health product, chemical, seasoning, personal care, disinfectant, and light industry packaging fields.

It is suitable for laundry detergent bottles, shampoo bottles, medicine bottles, seasoning bottles, beverage bottles, flat plastic bottles, square containers, and similar products requiring front and back labeling.

For manufacturers looking to improve automation, maintain symmetrical label placement, and reduce manual labeling errors, the automatic double side labeling machine provides a practical and reliable double-side labeling solution.
