Description

Technical Field

[0001] The utility model relates to the technical field of packaging and printing, in particular to an integrated concave-convex die-cutting and glue line applying device. Background Art

[0002] In the packaging and printing industry, die-cutting and glue line application are key process steps in making packaging boxes, labels and other products.

[0003] The traditional process usually performs die-cutting and glue line application as two separate steps, that is, die-cutting is performed first, and then glue line application is applied using a glue knife. However, this traditional process has exposed many drawbacks in actual application.

[0004] First, due to the separation of the die-cutting and gluing blades in the process sequence, the wear of the two is often inconsistent. In particular, the pressure of the gluing blade directly affects the pressure of the subsequent die-cutting blade, resulting in poor die-cutting results, paper fuzz, and machine jams. These issues not only affect product yields but also increase customer complaints, dealing a double blow to the manufacturer's reputation and economic benefits.

[0005] Secondly, when applying glue, the pressure distribution of the glue knife is often affected by the die-cutting knife, resulting in uneven pressure and varying depths. This uneven pressure distribution directly affects the glue application, resulting in poor glue absorption by the serrated knife, which can cause the glue to delaminate after molding. This not only reduces product quality but also increases the risk of customer complaints.

[0006] Furthermore, due to the interaction between the glue knife and the die-cutting knife during the production process, the pressure of both needs to be frequently adjusted to maintain a stable process effect. This frequent adjustment not only increases the complexity of production operations, but also accelerates the wear of the blade, resulting in prints that fail to meet process requirements, further increasing production costs.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0021] In the drawings, the same reference numerals all refer to the same components.

[0022] like Figure 1-2 As shown, the present invention provides an integrated concave-convex die-cutting and glue line application device, comprising a device body 1, which is composed of a paper feed unit 2 and a die pressing unit 3. The paper feed unit 2 is designed to be mounted at one end of the die pressing unit 3 and is used to stably feed the paper material to be processed to the die pressing unit 3. A paper feed port is provided at one end of the paper feed unit 2 to facilitate the continuous input of paper.

[0023] The embossing unit 3 is the core component, featuring an innovative internal layout. Specifically, it includes an embossing assembly 301, a half-cutting assembly 302, and a die-cutting assembly 303. The embossing assembly 301 is mounted on the far right side of the embossing unit 3, adjacent to the paper feed unit 2. It performs a preliminary embossing process on the paper, enhancing its three-dimensional effect and aesthetics.

[0024] Following the embossing assembly 301 is the half-cut assembly 302, which serves as a pre-treatment step before applying the glue line to the paper. This half-cut process provides a more precise surface for subsequent glue application, while also minimizing glue spillage and maintaining a neat product. The design of the half-cut assembly 302 cleverly pre-positions the glue line, preventing direct contact between the glue and the die-cutting blade 3031, thereby reducing wear.

[0025] Following the half-cutting assembly 302 is the die-cutting assembly 303, located at the very end of the die-stamping unit 3, near the discharge port. The die-cutting assembly 303 houses a high-precision die-cutter 3031, responsible for completing the final die-cutting operation, cutting the paper, which has undergone the embossing and glue-line treatment, into the desired shape and size. Because the die-cutting process occurs after the glue line is applied, the glue effectively prevents the die-cutter 3031 from being affected by the glue, ensuring the stability and accuracy of the die-cutting effect.

[0026] Furthermore, the outer surface of the molding unit 3 is equipped with a main control panel 305, which integrates all necessary control buttons and display screens, making it convenient for operators to monitor and adjust the entire device in real time, thereby improving production efficiency and operational convenience.

[0027] This utility model is an integrated concave-convex die-cutting and glue line application device. By adjusting the process sequence, the invention avoids direct contact between the glue knife and the die-cutting knife 3031, thereby reducing tool wear, extending the tool life, and lowering production costs. This change also ensures the stability and accuracy of the die-cutting process, effectively avoiding problems such as paper tearing and incomplete die-cutting, thereby improving product quality.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
