Description

Technical Field

[0001] The utility model relates to the technical field of paper box processing, in particular to a gluing mechanism capable of adjusting the amount of adhesive. 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 gluing mechanism applies a layer of adhesive on the face paper to be mounted so that the face paper is bonded to the top and bottom box board through the adhesive. However, the commonly used top and bottom box gluing equipment cannot control the amount of adhesive applied to the top and bottom box surface during use, resulting in too much or too little adhesive applied to the top and bottom box board surface, which can easily affect the bonding effect between the face paper and the top and bottom box, causing bubbles and wrinkles on the surface of the face paper or the face paper to fall off.
