Gift bag label pasting machine

Technical Field

The invention relates to a labeling machine, in particular to a gift bag labeling machine.

Background

Gift bags are manufactured by manufacturers and when sold in bulk to other companies, are typically required to have labels and related product information for each company affixed to the bottom of the gift bag. In order to facilitate the storage and transportation of the gift bags, the bottom of the gift bags needs to be folded, and when the labels are pasted, the gift bags are also in a folded state, and the labels are difficult to paste due to the special shape of the bottom of the bags. In the past, labels are mostly pasted on gift bags manually, and workers peel the labels from label tapes and paste the labels on products, so that the labeling speed is low, and the working efficiency is low. With the increasing degree of industrial automation, more and more manual production assembly steps are replaced by automated equipment.

For example, patent publication No. CN105691787A discloses an automatic labeling machine, conveying mechanism is used for carrying the product, the both ends of label area are respectively around locating winding mechanism and unwinding mechanism, winding mechanism rolls up this label area, when the label area passes through the wedge end, the label is peeled off from the label area, and paste and establish on the product through wedge end below, then, conveying mechanism will paste the product of establishing the label and carry to the gyro wheel below, the gyro wheel compresses tightly label and product, then, conveying mechanism will compress tightly the product of label and carry to color mark sensor department and detect, color mark sensor judges whether the product is pasted the label through the colour of response label, thereby realize that the product pastes the mark, compress tightly and detect.
