Description

Technical Field

[0001] The utility model relates to the technical field of paper box processing, in particular to a surface paper gluing mechanism. Background Art

[0002] The top and bottom cover refers to a type of box. The top of the paper box is the "top" and the bottom is the "bottom", so it is called the top and bottom cover. The top and bottom cover, also known as the top and bottom box, is widely used in various types of packaging boxes such as hardcover gift boxes, shoe boxes, underwear boxes, shirt boxes, mobile phone boxes, etc. With the increasing awareness of environmental protection, the global paper box / carton packaging industry has developed rapidly and production capacity has increased significantly. Folding paper boxes are widely used in the packaging of tobacco, alcohol, medicine, food, beverage, daily necessities, and handicrafts because of their low processing cost, convenient storage and transportation, suitable for various printing methods, easy molding and processing, suitable for automatic packaging, easy sales, display and recycling, and conducive to environmental protection. When producing and processing the top and bottom boxes, the mounting paper is the most demanding and tedious process in the box making process.

[0003] The existing gluing mechanism includes a gluing roller and a gluing roller. Glue is injected between the gluing roller and the gluing roller through a rubber hose. A bridge plate is provided under the gluing roller. When the facial paper is transmitted, it passes through the gluing channel between the gluing roller and the bridge plate. The existing bridge plate is fixed in vertical position and cannot be adjusted. It cannot be applied to facial paper of other thicknesses, resulting in that the facial paper cannot be brushed with glue, and the subsequent process of bonding the cardboard and the facial paper cannot be carried out.
