Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, integrally connected, or detachably connected; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art will understand the specific meaning of the above terms in the present invention in specific situations.

The anti-extraction die-cutting blade is shown in figures 1 to 3 and comprises a blade body 1, the upper end of the blade body 1 is a cutting edge, and the cutting edge cuts a paper shell to perform die-cutting operation during operation. The side end faces of the front side end face and the rear side end face of the blade body 1 are provided with a plurality of outward protruding anti-pulling protrusions 10, after the blade body 1 is installed in the installation groove of the die cutting die, large extrusion force can be generated between the anti-pulling protrusions 10 and the inner wall of the installation groove, accordingly, large friction force is obtained when the blade body 1 is subjected to outward pulling force, and the problem that the blade body 1 is prevented from being pulled out is effectively solved.

The height of the anti-pullout protrusion 10 is gradually increased from the bottom side of the blade body 1 to the blade edge side. The scheme is set based on the stress condition of the blade body 1 during installation, when the blade body 1 is installed, the height of the anti-pulling-out protrusion 10 in contact with the installation groove is gradually increased from low to high, the pressure between the installation groove and the anti-pulling-out protrusion is slowly increased, and the installation is more convenient.

Specifically, the anti-pulling-out projection 10 is a thin sheet, the thin sheet is tilted outwards, and the upper end of the thin sheet is a swingable free end. The tilting height of the thin sheet is gradually increased from bottom to top, when the blade body 1 is installed, the free end of the thin sheet swings to one side of the blade body 1 after being extruded, and extrusion force generated between the thin sheet and the installation groove is small, so that the generated obstruction is small; and after the installation, the slice outwards perks and extrudes the mounting groove inner wall, and when blade body 1 received the power of being pulled out outward, the slice had the trend of turning over a book downwards, and the frictional force of slice and the reaction force that resists turning over a book can effectively prevent that blade body 1 from being pulled out. When the blade body 1 needs to be taken down, since the mounting groove of the die cutting die is a through groove in general, the blade body 1 can be taken out only by applying force in the direction of mounting the blade body 1, and the thin sheet does not obstruct the blade body 1 from being taken out. Moreover, the processing of the thin sheet is very convenient, namely, a thin sheet can be externally fixed, and the anti-pulling-out protrusion 10 can also be formed by directly bending after cutting a part on the blade body 1.

The anti-pulling-out protrusions 10 are arranged on the end faces of the two sides of the blade body 1, so that the blade body 1 is guaranteed to be stressed evenly. Furthermore, the anti-pulling-out protrusions 10 on the two sides are arranged at intervals, so that the processing is convenient, and the blade body 1 can be uniformly stressed when in use.

This scheme still provides a cross cutting mould, and cross cutting mould includes the bottom plate and installs a plurality of on the bottom plate prevent extracting the die-cutting blade, be equipped with a plurality of mounting grooves on the bottom plate, prevent extracting the die-cutting blade install in the mounting groove. When the paper case cutting device is used, the die cutting die is connected with the power driving device and is driven to impact the lower die, so that the paper case placed on the lower die is cut into a required shape. In the use, when the paper case applyed the pulling force to blade body 1, the produced reaction force of the protruding 10 extrusion mounting groove inner wall of preventing extracting can effectively avoid blade body 1 to be extracted to make the cross cutting mould can keep normal work for a long time.
