After the product passes the quality inspection, it needs to be packaged to protect the product during transportation and prevent damage caused by bumps. After the product is placed in the packaging box, different labels need to be attached to the packaging box. Labeling machines are often used in labeling. Labeling machines are devices that use adhesive to attach paper or metal foil labels to specified products. The labels are attached to a label tape in advance. The label tape is driven to move by a label pulling assembly. The product that needs to be labeled also moves with the device. When the label tape moves to the product, the label on the label tape is peeled off from the label tape and attached to the product. Then, the label is pressed by a roller to make it stick to the product.
