[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0025] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0026] Please refer to Figure 1-Figure 2 As shown, the present invention discloses a die-cutting assembly, which is used to produce the die-cut paper 200. The die-cut paper 200 forms a three-dimensional mesh structure 21 after being stretched. The die-cut paper 200 is formed by directly die-cutting paper. Specifically, the die-cut paper 200 includes die-cutting marks 22, which include multiple rows of die-cutting lines 221 arranged in rows. The die-cutting lines 221 are provided with multiple die-cutting openings 222 at intervals. The die-cutting openings 222 form openings 211 after being stretched. The multiple openings 211 formed after stretching constitute the three-dimensional mesh structure 21.

[0027] Please refer to Figure 3-Figure 6As shown, the utility model discloses a cross-cutting cutting assembly including a rotating shaft 10 and a blade assembly 30. The blade assembly 30 is mounted on the rotating shaft 10. The blade assembly 30 includes a plurality of disc blades 31. The disc blades 31 are evenly spaced along the axis of the rotating shaft 10. The disc blades 31 include an integral sleeve body 311 and a plurality of cutting edges 312. The sleeve body 311 is sleeved on the rotating shaft 10. The plurality of cutting edges 312 are evenly spaced around the central axis of the sleeve body 311. In this embodiment, the cutting edges 312 of two adjacent disc blades 31 are staggered to cut out Figure 1 Cross-cut marks inside.

[0028] The original cutting solution used a wheel-type bottom knife and a wheel cutter for cutting. When installing the wheel bottom knife and wheel cutter, the distance between them needed to be adjusted very precisely for normal cutting. In addition, the wheel bottom knife and wheel cutter could get stuck during production. This application uses only one set of cutters, which can quickly cut during the paper tape conveyance, improve production efficiency, and is easy to install without the problem of knife jamming.

[0029] The cutting edge 312 comprises a cutting head 3121 and a connecting portion 3122. One end of the connecting portion 3122 is connected to the sleeve body 311, and the other end is connected to the cutting head 3121. In this embodiment, the entire disc blade 31 is a one-piece structure formed by stamping. The width of the cutting head 3121 gradually decreases as it moves away from the axis of the disc blade 31, thereby forming a pointed shape at the outermost side of the cutting head 3121 to facilitate cutting.

[0030] In an optional embodiment, a through hole portion 3111 in the shape of a regular polygon is provided on the sleeve body 311, and the shape of the rotating shaft 10 is adapted to the shape of the through hole portion 3111. This structure allows the disc blade 31 to rotate synchronously with the rotating shaft 10 after being installed on the rotating shaft 10, thereby avoiding the undesirable situation of relative rotation between the disc blade 31 and the rotating shaft 10. Raised positioning portions 3112 are provided on two opposite surfaces of the sleeve body 311, and the raised positioning portions 3112 of two adjacent disc blades 31 abut against each other. The raised positioning portions 3112 are provided to fix the distance between two adjacent disc blades 31. In another optional embodiment, a barrier is provided between two adjacent disc blades 31, and the barrier is used to fix the distance between two adjacent disc blades 31.

[0031] In this embodiment, the die-cut paper cutting assembly further includes two fixed plates 40, which are fixedly mounted on both ends of the rotating shaft 10 and fixed to the rotating shaft 10 by a plurality of locking bolts 50. During the assembly process, one of the fixed plates 40 is first fixed to one end of the rotating shaft 10, and then the disc blades 31 are placed one by one on the rotating shaft 10. After the disc blades 31 are placed, another fixed plate 40 is fixed to the other end of the rotating shaft 10 to compress all the disc blades 31 and position the disc blades 31. It should be noted that the blade edges 312 of two adjacent disc blades 31 are offset from each other.

[0032] In this embodiment, the cutting assembly also includes a connecting shaft 60 and a motor (not shown in the figure). The connecting shaft 60 is installed on the fixed plate 40, and the connecting shaft 60 is synchronously connected to the rotating shaft of the motor. The motor drives the disc blade 31 to rotate to cut the paper tape transmitted.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
