Description

Technical Field

[0001] The utility model relates to the technical field of paper product processing, in particular to a hot die-cutting device for paper product processing. Background Art

[0002] The hot die-cutting technology heats the special mold to a high temperature, and then brings it into contact with the paper material to be cut. Under the combined action of high temperature and high pressure, the paper is precisely cut. Hot die-cutting has a fast cutting speed and high production efficiency, which is a great advantage in mass production.

[0003] Since paper materials are light in weight, they are easily displaced during the hot die-cutting process, resulting in inaccurate cutting. To avoid this, the materials are currently mostly fixed manually, and the waste paper produced by cutting can only be cleaned by staff, but this operation method is very likely to cause injuries to workers.

[0004] In order to solve the above problems, we have made improvements and proposed a hot die-cutting device for paper product processing. Utility Model Content

[0023] The first movable plate 3 and the second movable plate 24 are pushed outward along the slide groove 2, and the end of the rotating rod 4 can be pushed out of the first movable plate 3 and the second movable plate 24. At this time, the space for replacing the paper roll can be increased and the difficulty of replacing the paper roll can be reduced. After the replacement is completed, the rotating rod 4 is clamped by pressing down with the clamping member 5 to prevent the rotating rod 4 from shifting without affecting its rotation.

[0029] Working principle: When using this hot die-cutting device for paper product processing, the paper material to be processed is wound on the feed roller shaft 6, and the paper material enters from the limit frame 12 on one side. After passing through the limit frame 12 on the other side, its end is fixed on the discharge roller shaft 25. The first movable plate 3 and the second movable plate 24 are pushed outward along the slide groove 2, and the end of the rotating rod 4 can be pushed out of the first movable plate 3 and the second movable plate 24.
