Description

Technical Field

[0001] The utility model belongs to the field of packaging box production, in particular to an automatic feeding and gluing system for packaging box body pieces. Background Art

[0002] As people's living standards improve, their expectations for products are becoming increasingly higher. With the dazzling array of goods available today, the first thing that catches the eye is often the product's packaging. Good packaging can be a significant sales booster, especially for high-end products. Packaging plays an even more crucial role in sales, particularly in attracting consumers, increasing product value, satisfying their spiritual needs, and consolidating the brand and corporate image.

[0003] Traditional packaging boxes are usually one-piece molding structures. Because their edges and corners need to be cut off, they cause serious material waste and high material costs. In order to reduce material costs, more and more people use split-type combined packaging boxes in production. Existing split-type combined packaging boxes require separate feeding of the box bottom sheet and the box body sheet, and need to be glued together to firmly fix the two parts. In order to facilitate bonding, the glue used for bonding is basically applied to the two overlapping sides and the bottom edge positions of the four sides of the box body sheet with four sides. The feeding and gluing of the existing box body sheet are either done manually or by machinery. The manual method is time-consuming and labor-intensive, with low production efficiency, low placement and gluing accuracy, which easily affects the quality of the finished product, and high labor costs. The existing mechanical method either has relatively complex equipment, high equipment cost, and a large floor space, or still has low production efficiency and cannot meet the requirements of large-scale rapid production. For this reason, people hope to have equipment with high cost-effectiveness, fast single-piece feeding speed, fast gluing, and accurate gluing position to complete these tasks. Utility Model Content

[0004] The utility model aims to provide an automatic feeding and gluing system for packaging box body sheets, which has fast sheet supply speed, fast gluing speed and accurate gluing position.
