Description

Technical Field

[0001] The invention relates to the technical field of three-roller gluing, in particular to an improved three-roller gluing mechanism and a use method thereof. Background Art

[0002] The three-roller gluing mechanism is a gluing module commonly used in laminating machines. The three-roller gluing mechanism is mainly composed of a glue roller, a transmission roller and a glue reducing roller. The three-roller gluing mechanism is widely used in production equipment in industries such as poster printing, paper making, and furniture interior decoration. The three-roller gluing mechanism has a long development time and has the advantages of evenly and stably applying glue and improving product production efficiency. The three-roller gluing mechanism can also meet the production needs of different products by adjusting the coating amount, and has a wide range of applications.

[0003] For example, a paper production compound machine with a quick-cutting mechanism is recorded in the patent document with announcement number CN114228167B. The scheme recorded therein releases the paper and the film respectively through a paper release device and a film release device, and then glue is applied through a gluing device. During the gluing process, the tightness of the paper can be adjusted by adjusting the height of the second guide roller, thereby adjusting the pressure of the paper on the trigger rod and controlling the speed of the gluing device to output glue. This paper production compound machine with a quick-cutting mechanism cannot maintain consistent glue application on the paper at different speeds, and gaps are easily generated when the gluing device outputs glue. When the speed is slow, the paper is subjected to long-term pressure on the trigger rod for gluing, which easily leads to excessive glue application, making it inconvenient to adjust the amount of glue applied to the paper, thereby reducing the quality of gluing.

[0004] Based on this, an improved three-roller gluing mechanism and a method of use are now provided, which can eliminate the disadvantages of the existing device. Summary of the invention
