Description

Technical Field

[0001] The utility model relates to a die-cutting device, in particular to a high-speed digital label die-cutting machine head and die-cutting equipment thereof. Background Art

[0002] Digital label cutting machine, with the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of various cutting machines must adapt to the requirements of the development of modern mechanical processing industry.

[0003] The application number is 202210959743.6, which discloses a high-speed digital label die-cutting machine head and die-cutting equipment, belonging to the field of cutting technology, including: a first position adjustment component; a second position adjustment component, connected to the first position adjustment component; a plurality of cutting heads arranged in a modular manner, connected to the second position adjustment component, wherein one of the plurality of cutting heads is used as a reference origin, and the remaining cutting heads are adjusted in sequence along the horizontal direction with respect to the relative distance between the cutting heads on the reference origin, and each cutting head includes a cutting knife, and the knife heads of two adjacent cutting knives are on the same horizontal line. The present invention realizes the synchronous cutting of multiple labels on the same horizontal line on digital label paper by setting a plurality of cutting heads, thereby improving the cutting efficiency. In addition, the movements between the two adjacent cutting heads are independent of each other, and the distance between the two adjacent cutting heads is adjustable, thereby realizing the equidistant or unequally spaced cutting between two adjacent labels on the same horizontal line.

[0004] The application number is 202210556086.0, which discloses a cutting head for a digital die-cutting machine, including: a frame; an X-axis assembly; a Y-axis assembly; a cutting knife pad; two Z-axis guide rails arranged left and right are provided on the front side of the Y-axis slider, a cutter head assembly is slidably provided on the Z-axis guide rail, a Z-axis servo motor is provided at the top of the Y-axis slider, and the Z-axis servo motor is connected to the cutter head assembly through a Z-axis lead screw. The cutting head of the digital die-cutting machine of the present invention has a reasonable structural design, and the overall cutter head assembly is lifted and lowered as a whole by a Z-axis servo motor, which improves stability. Each cutting cutter head can determine whether to cut according to the state of the knife selection cylinder; the cutting document can be automatically called by scanning the QR code with a camera; the cutting pattern is automatically positioned by a color code sensor; there is no need to customize, install and debug the cutter die, and high-speed, fully automatic digital die-cutting is achieved.

[0005] In the existing digital label cutting machines, the number of cutting heads is single or multiple. When there is a single cutting head, the single cutting head is controlled by a program to cut one by one on the cutting cardboard. On the one hand, this cutting method is relatively inefficient. On the other hand, if the program is wrong, it may cause the distance between two adjacent digital labels to be unequal, thereby reducing the cutting quality. When there are multiple cutting heads, most of them move as a whole, and it is impossible to carry out diversified production and individual adjustments according to actual needs. Even if they can be adjusted, the structure is relatively complicated. Utility Model Content
