Description

Technical Field

[0001] The utility model relates to the technical field of round knives, in particular to an inlaid type round carving knife. Background Art

[0002] A circular die cutter, or circular knife for short, is a type of die cutting tool that has a faster die cutting speed than a flat die cutting knife, can produce more precise and complex products, and has higher efficiency. It was first used in the post-press processing field, and later has made great progress in the electronics, pharmaceutical, daily chemical and other industries.

[0003] From simple single-knife die-cutting to multi-knife cooperation, from single-material die-cutting to a variety of special processes, from labor-saving to extremely high production efficiency, the circular knife has demonstrated its irreplaceable advantages.

[0004] In the production process of die-cut products, die-cut products are cut from raw materials by die-cutting knives. Therefore, waste is often generated in the production process of die-cut products. After the waste is generated, it is usually impossible to separate it from the die-cut product. Subsequent process steps are required to remove the generated waste, which reduces work efficiency and has poor practicality. Therefore, a block-type engraving circular knife is needed to improve the above problem. Utility Model Content

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

[0024] Example

[0025] See also Figure 1-3A block-type engraving circular knife comprises a circular knife 1, a first connecting shaft 2 and a second connecting shaft 3 are fixedly mounted on the circular knife 1, and a plurality of protrusions 4 are fixedly mounted on the outer wall of the circular knife 1.

[0026] See also Figure 1-4 A waste discharge mechanism is arranged in the circular knife 1, and the waste discharge mechanism includes an insert 6 and a vacuum pump 8. A plurality of through holes 5 are provided on the circular knife 1 and the insert 6, and a slide groove is provided on the insert 6. The insert 6 is slidably connected with the circular knife 1. A connecting pipe 9 is connected and installed on the vacuum pump 8. The connecting pipe 9 is located inside the insert 6. One end of the connecting pipe 9 is placed inside the insert 6 through the second connecting shaft 3. By starting the vacuum pump 8, the waste after cutting is sucked and discharged through the cooperation of the vacuum pump 8 and the connecting pipe 9, thereby realizing the waste discharge operation, achieving the effect of removing the waste, and improving the work efficiency.

[0027] See also Figure 1-3 The circular knife 1 and the insert 6 are connected by a limiting mechanism, and the insert 6 is slidably connected to the circular knife 1. The circular knife 1 and the insert 6 are fixed by the limiting mechanism. The limiting mechanism includes two bolts 7. The circular knife 1 and the insert 6 are provided with two threaded holes corresponding to the two bolts 7. The two bolts 7 are respectively threadedly connected with the corresponding threaded holes. The setting of the two bolts 7 makes the connection between the circular knife 1 and the insert 6 more stable.

[0028] See also Figure 1 and Figure 2 Two handles 10 are symmetrically fixedly mounted on the insert 6, and the arrangement of the two handles 10 facilitates the movement of the insert 6.

[0029] See also Figure 1-3 It should also be noted that each protrusion 4 is provided with a sharp corner, and the setting of the sharp corner makes each protrusion 4 sharper, thereby facilitating the die-cutting operation.
